er in the passenger compartment (e.g. on or in
front of the seats).
fSupport the cargo on the seat backrests when-
ever possible. Always lock the backrests into
place.
fPlace the cargo behind unoccupied seats
whenever possible.
fStow heavy objects as close to the front of the
cargo area as possible, with lightweight ob-
jects behind them.
fThe cargo must never project over the top
edge of the seat backrest.
fAlways protect the passenger compartment
with a luggage safety net and a luggage
compartment cover.
Do not drive with objects on top of the luggage
compartment cover.fIf the rear seats are not occupied, the back-
rests can be additionally secured with the safe-
ty belts. Simply cross the outer safety belts
and insert each into the opposite buckle.
fMake sure that the cargo cannot damage the
heating filaments of the rear window and the
TV antenna of the side window.

Towing a trailer
Warning!
Driving with a trailer
fAlways observe the permissible towing capac-
ity, vertical coupling load and rear-axle load.
Please observe the chapter “WEIGHTS” on
Page 363.
fWhen connected, the trailer must always be
horizontal behind the towing vehicle. If neces-
sary, use a trailer with an adjustable drawbar.
fWhen the vehicle is driven in the mountains, the
engine output decreases as altitude increases.
The maximum weights stated are the values at
sea level. The total permissable weight of the
car-trailer combination must therefore be re-
duced by 10% for each increment of 3,280 ft.
(1,000 meters) altitude. A fractional increment
counts as the full 3,280 ft. (1,000 meters).
Please take this into consideration when plan-
ning your route.Distributing the load
fDistribute the load in the trailer so that heavy
objects are as close to the axle as possible.
Always safeguard all objects against slipping
and tie them down securely.
fYou should make the best possible use of the
trailer coupling's rated vertical coupling load
when loading the trailer, but never exceed it.
Tire pressure
fSelect the vehicle tire pressure for full load
when towing a trailer.
fPlease observe the chapter “Tire pressure ta-
bles”.
fCheck the tire pressure of the trailer's wheels
according to the manufacturer's instructions.Door mirrors
fIf the width of the trailer obstructs your view of
the traffic behind the trailer, you must have ad-
ditional door mirrors fitted.
Headlights, lights
fAlways check the headlight adjustment before
driving with a trailer.
If necessary, correct with the headlight beam
adjustment function.
fCheck whether the plug of the trailer is
plugged into the towing vehicle and whether all
lights function.

Warning!
Risk of accident.
fDo not obstruct the pedal travel with floor mats or other objects.
Floor mats of the correct size and with the
appropriate fasteners are available from your
authorized Porsche dealer.The positions of the gears are shown on the shift
diagram on the gearshift lever.
fWhen shifting gears, always ensure that the
clutch pedal is fully depressed and the gear
has fully engaged.
fSelect reverse only when vehicle is stationary.
fSelect an appropriately low gear on upward
and downward slopes.
This will ensure optimum use of engine power
and engine braking.
When reverse gear is selected and the ignition is
on, the reversing lights are lit.
Permitted engine speedfYou should change into a higher gear before
the needle reaches the red mark on the
tachometer, or ease off the accelerator.
If the red zone is reached during acceleration, fuel
feed is interrupted.
Caution!
Risk of engine damage (overrevving) when
shifting down to a lower gear.
fTake care not to exceed the maximum permit-ted engine speed when down-shifting.

StoppingfFor a brief stop (e.g. at a traffic light), leave the
selector lever in drive position and hold the ve-
hicle with the brake pedal.
fDo not hold the car on a slope using the accel-
erator. Use the brake pedal or the parking
brake instead.
fBefore leaving the vehicle, always apply the
handbrake and move the selector lever to
positionP.
Tip on driving
In selector lever positions D and M, the Hillholder
prevents the car from rolling backward when it has
been stopped on an upward slope with the engine
running.
fPlease observe the chapter “HILLHOLDER” on
Page 224.
ParkingfGo easy on the accelerator.
fWhen parking or maneuvring in a small space,
control the speed by careful use of the foot-
brake.Driving in winterIn wintry road conditions it is advisable to take
steep inclines in manual mode M. This prevents
the occurrence of gear changes that could cause
wheelspin.
Reduced driving programIf there is a fault in the transmission:
–An X appears instead of the current gear
indicator on the multi-purpose display of the in-
strument panel.
The transmission no longer shifts.
fTo remedy the fault, immediately consult an au-
thorized Porsche dealer.
Warning!
Reverse gear lock monitoring is disabled in
the emergency running program.
Damage to the vehicle may result as well as
loss of control, if the vehicle is moving for-
ward fast enough to cause rear wheel lockup.
fDo not shift into R while the vehicle is moving forward.
Tip on driving
3rd or 5th gear in selector position D and reverse
gearR are now available and will allow you to
reach the nearest authorized Porsche dealer.
fPlease go to your authorized Porsche dealer

ABS
(Anti-lock Brake System)
Safety notes!
In spite of the advantages of ABS, it is still the driv-
er’s responsibility to adapt his driving style and
maneuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not in-
duce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed can-
not be reduced by ABS.
ABS ensures:
–Full steering control
The vehicle remains steerable
–Good driving stability
No skidding due to locked wheels
–Optimum braking distance
Shorter stopping distances in most cases
–Lock prevention
No flat spots on the tiresFunction
The decisive advantage of ABS is in the driving
stability and maneuvrability of the vehicle in
hazardous situations, even during heavy braking
while cornering.
ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable to
extremely rapid cadence braking.
The pulsating brake pedal and a “rattling noise”
warn the driver to adapt his driving speed to the
road conditions.Warning light
If the ABS warning lights light up in the instrument
panel and on the multi-purpose display of the in-
strument panel while the engine is running, the
ABS has switched off because of a fault.
In this event, the braking system will operate with-
out lock prevention,as in cars without ABS.
fAdapt your driving style to the changed brak-
ing behavior.
The ABS must be checked immediately at an
authorized Porsche dealer in order to prevent
the occurrence of further faults the effects of
which cannot be defined.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with non-approved dimensions can
lead to different wheel speeds, causing the ABS to
switch off.
