The new GLC-Class combines functionality and

responsi-veness in a modern SUV design The on-road and off-road

transmission modes and the AIR BODY CONTROL air

suspen-sion mean that the new GLC-Class can also offer driving

plea-sure off the asphalt Compared to the GLK-Class, the space

available in the interior compartment has also increased

Furthermore, the load compartment features a more variable

design thanks to the new cargo position

A PLUG-IN HYBRID variant with M274 and the new 4MATIC

transfer case are used in the new GLC-Class alongside the

M274 and OM651 engines

The new GLC-Class features telematics generation 5 A

sound system with front bass, amongst other features, is

available as special equipment

Voltage dip limiter

A voltage dip limiter is installed as standard on the new Class The GLC 350 e 4MATIC is an exception here The vol-tage dip limiter has the task of preventing the battery voltage from dropping below a defined voltage value during the inter-nal combustion engine starting procedure This is achieved

GLC-by temporarily limiting the starter current

and equipped with a three-part backrest The division ratio is

40:20:40 and is therefore more flexible than the predecessor

model series' 60:40 division For the new backrest in the

rear, the central element can be folded down individually or

in combination with the outer element on the driver side (for

left-hand drive vehicles)

The outer backrests in the rear can be electrically unlocked Activation buttons are installed next to the backrests in the area of the left and right side trim of the load compartment for this purpose In the special equipment stowage space package, additional activation buttons are included in the rear next to the backrests After unlocking, the backrests are folded forwards To bring the backrests into their original position, they must be manually folded back into place

Maintenance strategy/Assyst

New technical features

Model series 253, as with model series 205, is subject to

maintenance according to the new maintenance logic The

maintenance packages, especially Service A and Service B,

have been recompiled according to procedural and vehicle

technology-related criteria This has made it possible to

signi-ficantly reduce annual fluctuations in maintenance costs

However, the fixed maintenance interval of "every 25 000 km

(15 500 mi)/12 months", e.g for ECE, in addition to

kilo-meter intervals potentially deviating in the case of individual

countries, remains Furthermore, the A and B services

con-tinue to apply alternately and there is also a "PLUS package"

that the customer can choose at any time

Additional maintenance operations

Vehicle-specific additional maintenance work is subject to

the intervals described in the table The other maintenance

intervals remain unchanged

Maintenance strategy/Assyst

Which service contract suits me best? The vehicle-specific

service contracts enable the car customer to choose

indivi-dual protection while also allowing him/her to select the best

of the different product variants which are available

The purchasable warranty extension as an entry-level

pro-duct is geared towards security-oriented, price-conscious

customers These customers are protected against

unexpec-ted repair costs in the long-term even after the manufacturer

warranty expires

With the maintenance contract, the focus is on cost

trans-parency and reliable planning In this case, all maintenance

costs are covered for the agreed term The services include

all maintenance operations as per the service booklet

inclu-ding additional operations "subject to separate invoice"

The full service contract, as a premium product, combines all previously mentioned maintenance and repair work in ad-dition to all wear-related work With this all-in-one protection package, the customer can be sure that their Mercedes-Benz will stay in top form for a long time

The availability and product names for the Mercedes-Benz service contracts are defined on a country-specific basis

In the models GLC 250 4MATIC, GLC 300/300 4MATIC and

GLC 350 e 4MATIC, the familiar 4-cylinder M274 gasoline

en-gine from the C-Class is offered in several variants

The GLC 350 e 4MATIC, as a PLUG-IN HYBRID, contains an

electric motor in addition to an internal combustion engine

This helps to achieve a significant improvement in exhaust

and consumption figures In the other models, an

improve-ment was achieved by converting the charge air cooling The

charge air is no longer cooled by the air stream as usual; it is

instead cooled by a separate low-temperature circuit which

also flows through the transmission cooler

The special considerations of engine M274 are described below:

• Combination of direct injection with turbocharging

• Further developed combustion system and extended trolled ranges

con-• Fast-acting Piezo injectors for multiple injection of the fuel

• Demand-based multiple ignition

• Use of an electrical coolant pump with considerable

CO2 reduction potential thanks to led operation in the models GLC 250 4MATIC and GLC 350 e 4MATIC

demand-control-• Wide open throttle tank purging via venturi extraction

• Fulfillment of EU 6

The reliable OM651 4-cylinder diesel engine with 2.2 l

dis-placement is also used in the new GLC-Class with the output

variants 120 kW (Belgium), 125 kW and 150 kW

The characteristic features of this engine include the

following:

• Fuel injectors with 2000 bar injection pressure

• Two-stage turbocharging

• High-pressure exhaust gas recirculation

• Charge air bypass flap and an additional boost pressure sensor

• Volume-controlled oil pump with two pressure stages

• Switchable coolant pump

• Fulfillment of EU 6 in combination with AdBlue® exhaust aftertreatment

• In-engine friction loss optimization

Diesel engine OM651

Depending on the engine variant, the new GLC-Class is

equipped with various cooling systems which are comprised

of two independently operating coolant circuits

The high-temperature circuit (HT) cools the engine and

cy-linder head The HT also cools the exhaust gas turbocharger

(ATL) and the valves of the exhaust gas recirculation

Via the electrical circulation pump, the low-temperature

circuit (NT) cools the charge air, the automatic transmission

fluid and the power electronics of the PLUG-IN HYBRID

In the GLC 300/300 4MATIC with engine

M274 E20 DEH LA LS, a mechanical coolant pump is

instal-led in place of the electrical coolant pump

For engine variants M274 and OM651, a fan louver is used

The GLC 350 e 4MATIC is an exception here The fan louver

is also dropped if the vehicle is equipped with a trailer hitch

Because of the separate HT and LT cooling circuits, it

is necessary to fill and bleed the system twice when carrying out repair work

The hybrid vehicle contains additional components which

must be cooled in the form of the high-voltage battery,

char-ger and DC/DC converter Due to their requirements, they

need very low coolant temperatures, which may even be

below the ambient temperature The high-voltage battery and

the charger therefore require their own low-temperature

cir-cuit This principally consists of the following components:

• Low-temperature cooler

• Chiller, heat exchanger between refrigerant and coolant,

for cooling the high-voltage components at high ambient

temperatures

• Electronic circulation pump for appropriate regulation of

the coolant mass flow

• Electronic regulating valve for the appropriate distribution

of the coolant mass flow between the high-voltage battery

and charger

• Electronic switchover valve for the

temperature-depen-dent switchover between the low-temperature cooler and

chiller

• Expansion reservoir

The coolant temperature is kept below the ambient rature by using the switchover valve to completely divert the coolant from the low-temperature cooler to the chiller The chiller transfers heat to the refrigerant of the air conditioning system Its temperature is kept significantly below the am-bient temperature by means of the refrigerant circuit

tempe-For efficient cooling of the high-voltage battery, the phases

of the chiller cooling are kept as short as possible nal energy-saving potential in the low-temperature circuit is found in the interaction between the electronic regulating valve and the circulation pump Even here, only the currently required coolant mass flow is set to adhere to the tempera-ture limits

The exhaust system for vehicles with a 4-cylinder M274

gasoline engine is designed in three parts, and in four parts

for vehicles with a 4-cylinder OM651 diesel engine The

con-necting points are located downstream of the exhaust gas

turbocharger, the respective exhaust treatment components

and upstream of the rear muffler

Exhaust aftertreatmentThe BlueTEC technology means that the exhaust emissions

of vehicles with diesel engines can be substantially reduced

A water-cooled AdBlue® metering valve for metering the duction agent AdBlue® is installed directly downstream of the diesel particulate filter on the exhaust pipe

Further information about BlueTEC can be found in the system description "BlueTEC exhaust aftertreatment with AdBlue®"

OM651 BlueTEC exhaust system

The plastic fuel tank is installed in front of the rear axle and

below the rear bench seat In order to satisfy the

require-ments for permeation behavior, it is equipped with an

emissi-ons barrier layer

The volume of the small fuel tank is 50 l, the capacity of the

large fuel tank is 66 l The reserve volume is identical at 7 l

for both versions

The diesel incorrect fueling protection, which prevents filling the vehicle with gasoline, is new A special flap at the tank opening, which can only be opened using the larger diameter

of a diesel nozzle, prevents incorrect fueling with gasoline

The vehicles with diesel engines also have a tank for the supply of reduction agent AdBlue® (SCR) The process for external filling of AdBlue® is analogous to model series 205; i.e by means of a filling connection behind the fuel filler flap The supply module and the AdBlue® tank are located behind the right rear wheel

A PLUG-IN HYBRID is offered in the GLC 350 e for the new

GLC-Class The additional "E" on the liftgate is the easiest

way to recognize the hybrid vehicle version The hybrid drive

system allows the high-voltage battery to be externally

char-ged using a charge socket

ComponentsThe combined drive system consists of the 4-cylinder gaso-line engine M274 E20 DEH LA with 1 993 cm3 and the elect-rical machine

Intelligent HYBRID is the intelligent operating strategy for

hy-brid vehicles In order to implement the energy from the

high-voltage battery in the most efficient way while driving, the

Intelligent HYBRID monitors the road's course and the traffic

situation in a preventive way

Preventive functions

For the preventive functions, information from several

sys-tems is used The following preventive functions are available:

• Preventive driving strategy

• Radar-assisted regenerative braking

• Route-based operating strategy

• Haptic accelerator pedal

Preventive driving strategy

When approaching a vehicle driving in front, an upshift

pre-vention is initiated, i.e upshifting when releasing the

accele-rator is prevented If a faster vehicle is let past, for example,

it is possible to subsequently accelerate in a more suitable

gear Upshifting when releasing the accelerator and

down-shifting when operating the accelerator pedal are thereby

prevented If it is not possible to overtake, a higher vehicle

deceleration is provided by the engine overrun torque The

driver does not need to brake so much in order to avoid a

rear-end collision with the vehicle in front The aim of the

preventive driving strategy is to increase ride comfort and

im-prove vehicle agility The function is active in all transmission

modes, albeit in different versions The respective rotational

speed thresholds have been adapted to the individual

trans-mission modes

Radar-assisted regenerative brakingThe consumption of the vehicle is optimized by the radar-assisted regenerative braking system The electrical range is increased by more pronounced and prolonged regenerative braking and by sailing operation Greater convenience bene-fits are provided in the form of the support in deceleration mode for clearance and speed regulation tasks

No radar-assisted regenerative braking takes place under the following conditions:

• No vehicle is detected driving in front

• Vehicle driving in front too far away

• Vehicle driving in front is acceleratingWhen approaching a slower vehicle, deceleration is caused

by the regenerative braking system

Route-based operating strategy

The driver can use the various manually selectable PLUG-IN

operating modes for their routes They can thereby determine

where they would like to drive electrically or when the

high-voltage battery will be discharged

The route-based operating strategy takes the decision for

route-optimized operating mode sequences out of the

dri-ver's hands

The choice of operating mode therefore does not occur in an

event oriented way, but rather also taking into consideration

that the use of electrical energy takes effect in a way which

Haptic accelerator pedal

The haptic accelerator pedal supports the driver in

achie-ving an economic and convenient driachie-ving style Here, the

variable actuation point in the E-MODE operating mode and

the double pulse in the Economy transmission mode are

available

A tangible actuation point in the haptic accelerator pedal

sig-nals the maximum available electrical driving power available

at that point If the haptic accelerator pedal is depressed

past the actuation point, the internal combustion engine

swit-ches on

If the vehicle speed is higher than the vehicle driving in front, the driver will receive a recommendation to release the haptic accelerator pedal This is provided in the form of

a tangible double pulse in the haptic accelerator pedal The internal combustion engine can be switched off and decou-pled from the drivetrain The vehicle switches to sailing mode

or to radar-based regenerative braking In the transmission mode Individual, the double pulse can be switched on or off

The following conditions determine when the double pulse is triggered:

• Vehicle speed

• Clearance to the vehicle driving in front

• Speed relative to the vehicle driving in front

The hybrid vehicle permits purely electrical driving after the

key has been inserted The internal combustion engine is

started if the operating strategy decides that the driver's

requests can no longer be fulfilled purely by using electrical

power The requested power is detected by the accelerator

pedal module Silent Start takes place depending on the

out-side temperature and operating temperature of the internal

combustion engine No restrictions arise in terms of the

hea-ting comfort of the interior compartment or disadvantages in

terms of emissions The operational readiness of the hybrid

system is signalized by the READY indicator in the instrument

cluster

Starting and driving with a low load takes place either purely

electrically or in combination with the internal combustion

engine, depending on the operating strategy When

accelera-ting with an increased or full load, additional acceleration is

performed by the electrical machine

Electrical drivingDue to the large capacity of the high-voltage battery, purely electrical driving is possible over a distance of approximately

30 km The maximum speed for purely electrical driving is approx 140 km/h

If the performance of the electric motor is no longer cient, the internal combustion engine is switched-in This happens due to the following conditions:

suffi-• The limit speed is achieved

• Rapid acceleration

• High performance requirements

• Charge level of high-voltage battery below limit valueBefore closing the wet clutch in the automatic transmission, the vehicle electronics synchronize the rotational speeds of the internal combustion engine and the electric motor The switching-in takes place smoothly, so as to be unnoticeable for the driver

Furthermore, there are driving conditions in which the nal combustion engine is automatically started or not swit-ched off when the automatic air conditioning is switched in,

inter-or to heat the vehicle at low outside temperatures

Hybrid functions

ECO start/stop function

The ECO start/stop function switches the internal

combus-tion engine off when the vehicle is at a standstill The

elec-trically driven vacuum pump generates the required vacuum

for the brake system The steering and the refrigerant

com-pressor are also electrically driven This means that optimum

climate comfort is still possible when the internal combustion

engine is switched off Under certain operating conditions,

e.g in the transmission modes Sport or Sport Plus, the ECO

start/stop function is deactivated If the state of charge of

the high-voltage battery is below a certain value, the ECO

start/stop function is also deactivated

Regenerative brakingRegenerative braking has a considerable effect on the reduc-tion of fuel consumption In all phases of deceleration, the internal combustion engine is systematically switched off and the braking power is replaced by a charging torque generated

by the electrical machine

When the hybrid vehicle decelerates, there is a differentiation between three possible operating states:

• When coasting with pure deceleration, regeneration is already performed The electrical machine then functions

as a generator Recovered energy is then stored in the high-voltage battery

• If the brake pedal is only lightly actuated, the vehicle is decelerated more rapidly by the electrical machine and the regenerative braking is increased

• If the brake pedal is actuated more heavily, the wheel kes are also used to decelerate the vehicle In this driving condition, both systems work in combination with each other

in-External charging of the high-voltage batteryThe high-voltage battery can be charged at charging stations and using household sockets.

Sailing and radar-assisted regenerative braking

The sailing operating condition is possible in the Comfort

transmission mode below 130 km/h or in the Economy

transmission mode below 160 km/h

In the ECO transmission mode, energy production is reduced

to a minimum for the benefit of the radar-assisted

regene-rative braking The internal combustion engine also remains

switched off in this case The regenerative braking display

is reduced to a minimal value In this operating condition,

the energy is converted into a higher rolling speed and/or

into a longer rolling distance This is advantageous for longer

descents or for a preventive approach to traffic

lights/inter-sections The vehicle rolls more freely and is less rapidly

de-celerated than a conventional vehicle If a higher deceleration

rate is requested using the brake, the radar-assisted

regene-rative braking system switches off and the non-driven and

re-generative torque is automatically made available again

Further details can be found in the Technology Guide

for the ECO Start/Stop Function
