Sunroof

For the 911 Carrera (996) an electrically operated,

infi-nitely adjustable tilt-slide sunroof is available as an optional

equipment (RDW) and standard equipment for the North

American market The tilt function integrated in the

sunroof (opening height 28 mm) allows low-noise

ventila-tion of the vehicle's passenger compartment, even at high

speed

In contrast to the previous model 911 Carrera (993), the

roof opening is 18% larger (longitudinal direction) with

virtually the same width The small installation height of the

system increases head room by 36mm Direct coupling of

the actuator transmission to the sunroof motor has

resulted in a considerable reduction in operating noise

The sunroof is actuated via an illuminated rocker switch

which is integrated in the cover of the drive unit at the

front of the roof

Sunroof – 911 Carrera (997) (optional)

The electric sliding/tilting roof is available as an option on

the 911 Carrera/S (997) and is similar to the 911 Carrera

(996)

It is characterized by a low height and quiet running when

operated The noise optimized end position to which the

roof opens in response to "one-touch" opening has been

modified slightly to reduce the noise level (approx -10

mm) It can be opened beyond this point to its full extent,

if desired It is operated via the rear control unit

The switch has three switch settings corresponding to thefinal positions:

Close - Open - Tilt

The tilt-slide sunroof will operate:

l if the ignition is switched on (engine on or off)

l if the door is open

l if the door is closed and the ignition key is removed (butonly until the door is opened for the first time)

Similar to the window lifters, there are two operatingmodes for the sunroof:

1 One-touch function for open, close, and tilt.

Briefly pressing (approx < 300 ms) the appropriatebutton triggers automatic operation The sunroof can

be stopped at any position by briefly pressing thebutton again

2 Continuous operation for open, close, tilt, and lower.

The sunroof can be moved to the desired position bypressing the rocker switch The sunroof opens until itreaches a final low-noise position However, it can beopened completely by pressing the rocker switch again.Further closing functions are possible with the vehicle key:

l The roof can be moved to the desired position bypressing button in the remote control unit (at least 3seconds)

l The roof can be moved to the desired position byholding the vehicle key in the door lock at the lockingposition

Anti-jam Device

An anti-jam device which, if necessary, stops the motion ofthe sunroof and causes it to open again is integrated inthe closing cycle of the roof

Note:

If the vehicle is left unlocked for more than 2 hours, thesunroof can no be actuated (this is to protect the vehicle'sbattery)

Emergency Operation

The fuse D 3 should be checked before emergency

operation is performed

1 Using your fingernails or a screwdriver, carefully unclip

both panels covering the infrared passenger

compart-ment monitors

2 Remove both screws.

3 Lower the rear end of the cover over the tilt/slide

sunroof drive Remove the angled hexagon socket

wrench from its holder

4 Insert the hexagon socket wrench into the drive axle.

Sunroof Emergency Operation

5 Push and hold down the hexagon socket wrench into

the drive axle Then rotate the wrench clockwise until

the tilt/slide sunroof is closed

6 Remove the hexagon socket wrench Close the cover

and screw in the screws

Note:

The tilt/slide sunroof must not be operated if emergency

operation has been performed

The sunroof is opened, closed, tilted, and lowered by theelectric drive (1) The system functions using a gearwheeland cables The cables are flocked The entire sunroof is asingle assembly unit (2) and is attached to the appropriatemounting points of the vehicle's roof frame using the bolts(3) The mounting points (6) which are screwed to the sidebrackets (8) with the bolts (7) are attached to the sunroofcover (5) The sunroof panel liner (9) is attached and made

of plastic

The side brackets form the connection between the cablesand actuate the wind deflector (10) When the sunroof isopened, the spring-loaded wind deflector raises automati-cally When the roof is closed, the guide slide pushes thewind deflector down by means of a wire Water drainagenozzles to which drainage pipes are connected areattached to the front and rear of the assembly unit

Note:

If the sunroof cover has been removed, the sunroof drivemust not be operated electrically

Trang 9

“Hard” Roof & Body Systems Page 1.5

Adjustment

The height and opening gap of sunroof cover can be adjusted at the

labeled screws.

Initialization

The position of the sunroof is detected using Hall-effect

sensors The tilt position is used as the zero position and

stored in the EEPROM The drive calculates the number of

motor revolutions required for the “closed” and “open”

positions to be reached from the zero position

If the sunroof is being commissioned or the contents of

the memory have been lost, the drive unit must be

reinitial-ized Interruptions in the voltage supply, e.g if the

vehicle's battery is changed, will not result in memory loss

if the motor was not being operated at the same time

However, if the voltage is interrupted while the motor is

being actuated, reinitialization is required

Reinitialization can be performed at any time This is done

by holding down the rocker switch in the “close” position

for 10 seconds with the sunroof already closed The roof

then goes through the initialization procedure

Body – 911 Targa (996)

General

The 911 Targa (996) is basically the same as the 911

Carrera below the window line To achieve this the side

section, starting with the 911 Carrera Coupé, had to be

shortened below the window line The roof module (glass

sun roof, folding rear window, the roller blind for heat and

cold protection, including attachments and fasteners) is

at-tached to the basic bodyshell Both the windshield filler

panel between the windshield and the glass sun roof and

the side roof moldings are always finished in highly

polished black, regardless of the exterior body color

Luggage Compartment

With its vertically positioned high-pressure spare tire, the

911 Targa has the same luggage compartment as the

911 Carrera Coupé (996) with a capacity of 4.6 cu.ft

(130 liters) As a result of accessibility through the folding

rear window, the interior space is considerably more

useable and can be made more versatile by folding down

the rear seat backs In addition, the maximum storage

capacity of 8.1 cu.ft (230 liters) resulting from the

change in the roof line shape compared with the Coupé

Body Shell

The body structure of the 911 Targa is basically the same

as that of the Coupé The modifications and the changesmade to the Coupé for the 2002 model year to improverigidity were adopted

Targa Body Shell

The side roof frames have been improved in strength andrigidity Along with the reinforcing tubes integrated into theroof rails this results in an extremely strong passengercompartment

Front Water Drain

The drain pipe is located to the side at the assemblyframe for the roof module The hose for the water drain ispushed on and runs along the inner edge of the windshieldframe to the discharge opening at the hinge pillar

Trang 11

“Hard” Roof & Body Systems Page 1.7

Rear Water Drain

The outer rear water drain hose is pushed onto the roof

module drain support The inner rear water drain hose is

pushed onto the upper drain channel of the roof module

Both hoses are run in the rear side area

Deformation Member

Page 1.8 “Hard” Roof & Body Systems

Glass Sun Roof

The glass roof consists of 7.45 mm thick VSG/TVG glass

(laminated safety glass/partially tempered glass) The

benefit of the types of glass used is first of all the splinter

characteristics of laminated safety glass The plastic foil

sandwiched between two sheets of glass prevents the

glass from splintering and thus eliminates the risk of injury

from glass fragments in the event of breakage Tempered

glass is used on the other hand to ensure meeting

required quality standards with its high dimensional

accuracy

To ensure low wind noise at the Coupé level even at high

speeds, a sealing system was developed that seals from

below The benefit of this sealing system is the increasing

sealing function at high speeds As a result of the

increas-ing vacuum on the outer contour of the roof, the large

glass roof is pushed farther into the sealing strip and is

thereby additionally sealed With the rest of the extensive

sealing measures an extremely high degree of tightness

and complete suitability for automatic car washes has

The wind deflector extends across the entire width of theroof opening The extension height, the design shape andthe approach angle were optimized with respect to draft-free driving, wind noise and drumming

The wind deflector itself consists of a black coated metal airfoil and is controlled automatically bymeans of a spring-loaded rotation and sliding mechanismwhen the glass roof is opened and closed

Body – 911 Targa (997)

General

The new 911 Targa 4/4S (997) has an unique glass roof

design, which combines the benefits of turbulence-free

“open-top driving” with the comfort and safety features of

a Coupé – in other words: a more rigid body combined

with a greater sense of safety When closed, the new 911

Targa 4/4S models with their bright, light immersed

inte-rior guarantee a unique driving experience

The new 911 Targa 4/4S unmistakeably bears the

features of the current 911 generation For the first time

ever, the new 911 Targa 4/4S models are available

exclu-sively with full time four-wheel drive and a body that is 44

mm wider in the rear area than the rear wheel drive 911

Carrera models

Body Shell

The body shell of the new 911 Targa 4/4S (997)

corresponds below the window line to the ‘wide body’

shape of the four-wheel drive 911 Carrera 4 Coupés The

rear quarter panels, which are 22 mm wider on both sides

in the rear area, and the adapted rear and side skirts are

characteristic of this body shape

The bodyshell is constructed as a light-weight design with

high strength and ultra-high strength steel Despite the

glass roof assembly and the additional body

reinforcements, the new 911 Targa 4 weighs only 3329

lbs (1510 kg) while the Targa 4S weighs 3384 lbs (1535

kg) (empty weight with manual transmission)

The roof assembly is bolted all the way around to thestructurally optimized and higher-strength bodyshell Gusset plates connect the roof structure to the adopted

911 Carrera 4 Coupé base Together with the 30 mmthick, high-strength steel reinforcement tubes, which areintegrated in the A-pillar and in the roof pillars, excellentbody rigidity is achieved that is almost on a par with theCoupé models The B-pillar goes from the body side panel

to the roof pillar, where it is welded in The roof pillarsform a continuous line from the A-pillar to the end of the C-pillar – with no gaps or connection points whatsoever

Passive Safety

Both 911 Targa 4/4S (997) models have a body shell

structure designed to suit the specific requirements of a

vehicle with a large roof opening area This body shell

structure is light-weight, has extremely high torsional

rigid-ity and includes all the design features required to provide

excellent passive safety

High-strength steel tubes and panels were used to

guaran-tee the required body rigidity despite the large body shell

opening in the roof, particularly in the event of a rollover

These 30 mm thick reinforcement tubes run through the

A-pillar, then through the entire roof pillar and end at the

C-pillar, where they are joined to the body base by strong

gusset plates

B-pillar Tube Reinforcement

The joint between the B-pillar reinforcement and inner

wheel housing has been modified by inserting a gusset

plate In addition to the 3-point automatic seat belts with

belt pre-tensioners and force limiters on the front seats,

the new 911 Targa 4/4S is equipped with six airbags as

standard These include two-stage full-size front airbags

for driver and front-seat passenger and the Porsche Side

Impact Protection system (POSIP) comprising one thorax

airbag in the front seat backrests, a separate head airbag

in the door trim panels and side impact protection in the

doors on each side of the vehicle.The linings on the side

roof pillars are designed as energy absorbing elements

and provide even greater protection for the occupants

The glass in the sliding sunroof is made of two-sheets of

partially prestressed laminated safety glass and complies

with DOT requirements With the 6.3 mm thick laminated

safety glass, a plastic film sandwiched between two 2.6

mm thick panes of laminated safety glass prevents the

glass from shattering, thereby reducing the risk of injury to

occupants in the event of an accident

Body Equipment, Exterior – 911 Targa (997)

General

The glass roof assembly integrated in the body gives the

911 Targa 4/4S (997) models a unique look Thesilhouette appears elegantly long thanks to the rear sidewindows, which converge in a point towards the rear, anddifferentiates it from the 911 Carrera models The sidedrip mouldings and the cowl panel cover are alwaysfinished in high-gloss black regardless of the exteriorcolor This Plexiglas cowl panel cover is located betweenthe windshield and glass sliding roof and gives a continu-ous glass-roof look all the way from the windshield to theback window The elegant design of the rigid roof line isfurther accentuated by the polished and anodizedaluminum side trim strip along the roof frame

Roof Assembly

The completely pre-assembled roof assembly is installedand bolted to vehicle bodyshell A sealing strip runs all theway around seals the joint between the roof assembly andbody

Trang 40

Page 2.8 “Hard” Roof & Body Systems

The roof line and the division of glass areas is designed to

achieve as flat a look as possible when the glass sliding

roof is moved back under the rear window A compact

guide mechanism in the sliding sunroof ensures

comfort-able interior dimensions without forfeiting the roof line that

is typical of the 911

The maximum transport volume in the interior with the rear

seat backrests folded down is 8.1 cu.ft (230 liters),

thanks to the modified roof line guide and the further

recessed trim panel on the rear cross member, thereby

offering almost 1 cu.ft (25 liters) more space than in the

Coupé

The backbone of the glass roof assembly is an integral

steel-plate assembly frame, which accommodates the

glass sliding roof with drive mechanism, air deflector,

roller blind and hinged rear window as well as the closing

aid

The design and mechanics of the roof assembly areessentially the same as on the previous model 911 Targa(996) The assembly frame has an integrated water man-agement system, which clears away any water that dropsdown when the sliding sunroof or rear window is open Abar between the glass sliding roof and rear window is usedfor fitting center-joint and rear lid seals and for securingthe sliding roof seal

The complete roof assembly is secured to the roof pillars,the windshield frame and the rear cross members from below Black tinted Plexiglas covers, with their thinly pro-truding rubber lips overlapping the glass elements, form aflush transition to the body They not only minimize windnoise, but their black, high-gloss surface also adds to theglass look

The lift mechanism joins the glass sliding roof to theassembly frame and its guides On the new 911 Targa4/4S (997) models, this lift mechanism has an optimizedspring mechanism with three cup springs, which absorbstransverse acceleration caused by vehicle movements andprevents noises, particularly on bad road surfaces Whenlowering the roof, the lift mechanism is guided in a two-section plastic gate link, which is riveted to the sides ofthe assembly frame

Guide rails are riveted to the retaining frame of the roof assembly at the left and right to facilitate longitudinalmovement of the glass sliding roof Two sliding blocks,which carry the sliding roof, run to the left and right ineach of these aluminum rails Damping with respect to thevertical axis has been improved by using a new limit stop

in the guide rail
