Note
fAfter switching on the ignition, the
PASSENGER AIR BAG OFF warning light lights
up for a few seconds as a check.
PASSENGER AIR BAG OFF indicator lamp
lights up
The passenger’s air bags are switched off.
PASSENGER AIR BAG OFF indicator lamp
does not light up
The passenger’s air bags are active and ready for
operation.
Danger!
Risk of serious personal injury or death due
to the passenger air bag triggering
unintentionally.
When the ignition is on and the up to one-
year old child is seated in the child restraint
system on the passenger seat the indicator
lamp “PASSENGER AIR BAG OFF“ must be
on.
If the “PASSENGER AIR BAG OFF” indicator
lamp does not light up, it could indicate a
fault in the system, and the air bag could
inflate in a collision, placing the child at risk
of death or severe injury from the inflating air
bag.
In this case:
f Fasten the child restraint system on one of the
rear seats immediately.
f Have the fault remedied at your nearest authorized Porsche dealer. Faults are indicated by a warning light in the
instrument panel.
The air bag warning light illuminates when the
electronic monitoring of the air bag system
detects a malfunction of the
sensors, safety belt
system, occupant detection system, PASSENGER
AIR BAG OFF indicator lamp, related wiring, air bag
modules and control units.
f In the following cases you should
immediately consult an authorized
Porsche dealer in order to assure the air
bag system is functioning properly:
– If the warning light does not light up when the ignition is switched on or
– If the warning light does not go out once the engine is running or
– If the warning light appears while driving.

Warning!
f Do not obstruct the pedal travel with floor mats
or other objects.
The brake booster is ready for operation only
while the engine is running.
If the engine is switched off or there is a defect in
the brake booster, much greater force has to be
applied to the pedal when braking.
f Vehicles with defective brakes must not
be towed and must be transported on a flat
bed.
For information on towing and tow-starting:
f Please see the chapter “TOWING” on
page 316.
In heavy rain, while driving through water or after
leaving a car wash, the braking action may be
delayed and increased pressure may be required.
f For this reason, keep further back from the
vehicle in front and “dry” the brakes by
applying them at interval s. Make sure that the
traffic behind you is not affected. After a long drive over salted or gritted roads,
a coating may form on the brake discs and pads
that significantly reduces
friction and therefore
also braking effect.
f Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to
corrode if your vehicle is parked for an
extended period. The brakes will tend to “rub”
as a result.
The nature, extent and effects of corrosion
depend on the amount of time the vehicle was
parked, whether road salt or grit was spread
and whether grease-dissolving agents were
used in car washes (not on vehicles with
Porsche Ceramic Composite Brake).
To prevent corrosion of the brake discs,
“brake them dry” before parking the vehicle
(not on vehicles with Porsche Ceramic
Composite Brake).
If braking comfort is no ticeably impaired, we
recommend that you have the brake system
checked by an authorized Porsche dealer. f
To relieve the brake system on downhill
stretches, change down to a lower gear in
good time (engine braking).
If engine braking is insufficient on steep
stretches, operate the footbrake at intervals.
Avoid continuous braking as it overheats the
brakes and reduces the braking effect.
For information on brake fluid and checking the
brake fluid level:
f Please see the chapter “BRAKE FLUID” on
page 258.

Driving and Driving Safety

ABS Brake System
(Anti-Lock Brake System)
Warning!
In spite of the advantages of ABS, it is still the
driver’s responsibility to adapt his driving style and
maneuvers in line with road and weather
conditions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physic s of driving cannot be
overcome, even with ABS.
Risk of accidents due to inappropriate speed
cannot 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 distance in most cases
– Prevention of wheel locking
No flat spots on the tires Function
The decisive advantage of ABS lies in the driving
stability and maneuverability of the vehicle in
hazardous situations.
ABS prevents locking of
the wheels during full
braking, on almost all road surfaces, until just
before the vehicle stops.
ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f If full braking is necessary, press the brake
pedal fully during the whole braking operation,
even though the pedal is pulsating. Do not
reduce brake pressure. If the ABS warning light lig
hts up on the instrument
panel while the engine is running, the ABS has
switched off because of a fault.
The warning message “ABS failure” appears on
the multi-function display in the instrument panel.
For information on warning messages on the
multi-function display:
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
In this case, the brake system will operate without
lock prevention, as on vehicles without ABS.
f Adapt your driving style to the changed
braking behavior.
The ABS must be checked by your authorized
Porsche dealer in order to prevent the
occurrence of further faults with unpredictable
consequences.
Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
The ABS control unit is adjusted for the approved
tire dimensions.
The use of tires with no n-approved dimensions can
lead to different wheel speeds, causing ABS to
switch off. Warning light USA

Minor Repairs
Self-adhesive weights must not come into contact
with cleaning agents, since they could drop off.
Uneven tread wear indica
tes wheel imbalance. In
this event, the vehicle should be checked at an
authorized Porsche dealer.
Danger!
If, during a trip, uneven running or vibrations
occur that could be caused by damage to
tires or the car, the speed must be reduced
immediately, but without braking sharply. If
you continue your trip without having the
cause of the fault reme died, you might lose
control of your vehicle which could cause
serious personal injury or death.
f Stop the vehicle and check the tires.
f If no cause for the fault can be found, drive
carefully to the nearest authorized Porsche dealer.
Wheels with Tire Pressure Monitoring
(TPM) sensorsBefore changing wheels, make sure that the
wheels are compatible with your vehicle’s TPM.
fCheck this with your authorized Porsche
dealer.Removing and storing tiresfAfter changing, adjust tire pressure and torque
wheel bolts diagonally.
Please see the chapter “CHANGING A WHEEL”
on page 291.
f Store tires in a co ol and dry place. Rotate
periodically to avoid flat spots.
f Avoid contact with fuel, oil and grease.
Tires must always remain on the same side of
the vehicle.
When wheels are removed, the direction of
rotation and position of each wheel should be
marked. Example
FR (front right), FL, RR and RL.
Wheels must always be fitted in accordance with
their marking.
The perception that tire durability and
performance are not affected by storage and age
is unfounded.
Chemical additives, which make the rubber
elastic, lose their effectiveness over the course of
time and the rubber becomes brittle and cracks.
Therefore, the tires should be inspected from
time to time.
Note
Under no circumstances should tires older than
6 years be used on your Porsche.
The age of the tire can be obtained from the ”DOT“
code number. If, for example, the last three
numbers read 1208, then the tire was produced in
the 12th week of 2008.

1. Switch ignition on.
2. Switch on low beam.
3. Open engine compartment lid.
4. Place allen key (6 mm) on adjusting screw.
5. Adjust low beam in direction of the arrow.
TowingCertain state statutes and local ordinances
prohibit towing with a chain, rope or even a tow
bar. In addition, damage to your vehicle may result
from improper precedures. Consult your
authorized Porsche dealer for details.
Flat bed towing is the pref
erred type of towing to
be used on Porsche vehicles.
Tips on driving
f Always observe the laws governing towing and
tow-starting.
f Exercise extreme care when your vehicle is
being towed.
– If a turn signal is operated when the ignition and emergency flasher is switched on, only the
turn signal on the corresponding side of the
vehicle lights up. The emergency flasher is
switched back on again when the turn signal is
switched off.
Warning!
Risk of accidents. No power assistance is
available on the towed vehicle when its
engine is not running. Greater force is
therefore required when braking and
steering.
f Exercise extreme care when your vehicle is being towed.
When the engine is not running, adequate
lubrication of the transmission is not guaranteed.
Observe the following points to avoid damage to
the transmission.
Panamera STowing a vehicle with PDK transmission on all
four wheels
Caution!
We urge that wherever possible, a car
transporter or trailer be used to transport a
Panamera vehicle that cannot move under
its own power. This is the safest way to
transport a down vehicle.
For those instances where a car transporter or
trailer is not available, the vehicle may be towed
on all four axles only, provided the following
conditions are strictly me t. Failure to meet these
conditions will result in serious and expensive
damage to the PDK transmission.
