Operation, Safety
Child Restraint SystemsfDo not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be
equipped with the LATCH system.
Porsche recommends that all infants and children
be restrained in child restraint systems at all times
while the vehicle is in motion in accordance with
applicable laws.
Use only child restraint systems with the LATCH-
system recommended by Porsche. These sys-
tems have been tested and adjusted to the interior
of your Porsche and the appropriate child weight
groups. Other systems have not been tested and
could entail an increased risk of injury or death.
You can obtain child seats that are LATCH compa-
tible at your authorized Porsche dealer.
f Always see the separate installation
instructions for your child seat.
The use of infant or child restraints is required by
law in all 50 states of the U.S. and all Canadian
provinces. The child restraint system should be
one that complies with U.S. Federal Motor Vehicle
Safety Standards and should be secured by a lap
belt or lap belt portion of a lap-shoulder belt or for
child seats equipped with the LATCH sytem ( Lo-
wer Anchorage and Tether for Children, also
known as ISOFIX) to the LATCH anchorages.
A statement by the seat manufacturer of compli-
ance with this standard can be found on the in-
struction label on the restraint and in the instruc- tion manual provided with the restraint.
Danger!
The use of a child restraint system in the pas-
senger seat can result in serious personal in-
jury or death to the child from an airbag
deployment.
To reduce risk of injury from an inflating air-
bag in an accident, Po rsche strongly recom-
mends:
f Please see the chapter “PASSENGER AIRBAG
OFF INDICATOR LAMP DOES NOT LIGHT UP”
on Page 47.
f Please see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 50.
f Do not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be equipped with the LATCH system.
Note
The key switch for switching off the passenger’s
airbag and the LATCH attachment bracket are not
installed at the factory. Th ey can be retrofitted (not
on vehicles with Sports bucket seats).
f Please see your authorized Porsche dealer.
Danger!
Risk of serious personal injury or death to the
child.
f Follow all child restraint instructions and warnings in this manual.
– When using an infant or child restraint system, be sure to follow all manufacturer's instruc-
tions on installation and use.
– Infants and small children should never be held on the lap, nor should th ey share a safety belt
with another occupant while the vehicle is in
motion.
– Children too big for child restraint systems should use regular safety belts. A shoulder belt
can be used providing it does not cross the
face or the neck of the child.
– Choose a child restraint system according to the weight of the child.
– Child restraint systems that are damaged or h a v e b e e n h e a v i l y s t r e s s e d i n a n a c c i d e n t m u s t
be replaced immediately.
– Children could be endangered in a crash if their child restrains are not properly secured in the
vehicle.
– Do not affix things to child restraint systems or cover it with other materials.

Sports Exhaust SystemSwitching on and offThe sports exhaust system can be switched on
and off when the ignition is switched on using the
button.
When the sports exhaust system is switched on,
the light-emitting diode in the button lights up.
Parking Brake Parking brake force is mechanically transferred to
the rear wheels by means of cables.
f Use the parking brake only after the vehicle
has come to a full stop.
Setting the parking brake f Pull the lever all the way up (arrow ).
With the ignition on, the parking brake warning
lights in the instrume nt panel and on-board
computer will come on if the lever is even
slightly raised. A firm pull upward is required to
properly engage the parking brake.
If the brake is not fully set, the vehicle may roll
without control.
f Move the selector lever to “P” (PDK) or move
the gearshift lever to reverse or first gear
(Manual transmission).
f Before exiting the vehicle, make sure that the
parking brake is fully se t and the vehicle is not
moving at all.
Danger!
Risk of serious personal injury or death. A
partially engaged parking brake may allow
the vehicle to roll, ca using serious personal
injury or death to any person in its path.
f Engage the parking brake fully.Releasing the parking brakefPull the lever slightly up as you depress the re-
lease button, and then push the lever all the
way down.

56
Operation, Safety
The warning lights in the
instrument panel and on-
board computer will go out after the parking brake
is fully released.
The warning lights are not an indicator that the
parking brake is fully set; it is only intended to be
a warning to release the parking brake before
driving the car. Caution!
A partially engaged brake will overheat the
rear brakes, reduce their effectiveness and
cause excessive wear.
f Release the parking brake fully.
f When parking your car, always set the parking
brake by pulling all the way up on the lever.
f Move the selector lever to “P” (PDK) or move
the gearshift lever to reverse or first gear
(Manual transmission).
f On hills also turn the front wheels towards the
curb.
Brakes fMake it a habit to chec k the operation of your
brakes before driving.
Keep in mind that the braking distance increases
very rapidly as the speed increases. At 60 mph or
100 km/h, for example, it is not twice but four
times longer than 30 mph or 50 km/h. Tire trac-
tion is also less effective when the roads are wet
or slippery.
f Therefore, always maintain a safe distance
from the car in front of you.
Vehicles without Porsche Ceramic Compos-
ite Brake (PCCB)
Even though the brake discs consist of alloyed
grey cast iron, they will unavoidably start to cor-
rode if your car is parked for an extended period.
The brakes will tend to “rub” as a result.
The nature, extent and effects of corrosion de-
pend on the amount of time the vehicle was
parked, whether granular or liquid road salt was
spread and whether grease-dissolving agents
were used in car washes.
To prevent corrosion of the brake discs, ”brake
them dry“ before parking the car.
If the braking comfort is noticeably impaired, we
recommend having the brake system checked by
experts at an authorized Porsche dealer.
Brake system function Your Porsche is equipped with a power assisted
hydraulic dual circuit brake system with disc
brakes at the front and rear.
Both circuits function independently. One brake
circuit operates the front and the other operates
the rear.
If one brake circuit has failed, the other will still op-
erate. However, you will notice an increased pedal
travel when you apply the brakes.
Failure of one brake circuit will cause the stopping
distance to increase.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
In the unlikely event of hydraulic failure of
one brake circuit:
f Push the brake pedal down firmly and hold it in
that position.
A mechanical linkage activates the second cir-
cuit, and you will be able to bring the vehicle to
a stop.
f After bringing your vehicle to a complete stop,
avoid driving the vehicle and instead have it
towed to the nearest authorized Porsche deal-er for repair.

Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the "On" position and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer go on while driving, the brake flu-
id level may be too low, or (if the brake pedal travel
has increased) one of the two brake circuits may
have failed.
A greater braking pressure will be required, stop-
ping distances will be longer and the braking be-
havior will change, particularly in curves.
With correctly adjusted brakes, and a correctly
working brake system, the pedal travel to the
point of brake actuation should be 1-3/16 in. to
1-9/16 in. or 30 to 40 mm.
Whenever the brake pedal travel exceeds this dis-
tance, have the brake system checked.
Brake pedal
Warning!
Risk of an accident, re sulting in serious per-
sonal injury or death.
Any obstruction of the brake pedal could
increase the stopping distance.
f Always check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor ma t or any other object.
f Secure the floor mat to prevent it from sliding
into positions that could interfere with the safe
operation of your vehicle.
Your Porsche dealer will be glad to offer you nonskid floor mats of the correct size.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your
vehicle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
f Before descending a steep grade, reduce
speed and shift the tran smission into a lower
gear or driving position to control speed.
f Do not “ride the brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
f Do not hold the pedal down too long or too
often.
This could cause the brakes to get hot and not function properly.
f Please see the chapter “DRIVE-OFF ASSIS-
TANT” on Page 177.

Operation, Safety
Brake booster The brake booster assists braking only when
the engine is running.
When the car is moving while the engine is not run-
ning, or if the brake boos ter is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
If this happens, ABS and PSM will also not oper-
ate.
Moisture or road salt on brakes affects braking.
Brakes will dry after a fe w cautious brake applica-
tions.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
Driving through water may reduce the trac-
tion.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
f Cautiously apply brakes to test brakes after ex-posure to road water, etc.
Brake wear Your car has excellent brakes, but they are still
subject to wear. The rate at which they wear de-
pends on how the brakes are used.
f Have the brake system inspected at the
intervals recommended in your Maintenance
Booklet.
Brake system warning light
You can check the functionality of the brake
system warning light by switching the ignition to
the "On" position and verifying that the warning
light illuminates.
If the warning lights in the instrument panel and on-
board computer stay on when the engine is run-
ning or come on while driv ing, the brake pads are
worn excessively.
f Do not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads and brake discsWear on the brake pads and brake discs depends
to a great extent on the driving style and the con-
ditions of use and therefore cannot be expressed
in actual miles on the road.
The high-performance brake system is designed
for optimal braking effect at all speeds and tem-
peratures.
Certain speeds, braking forces and ambient
conditions (such as temperature and humidity)
therefore might cause “brake noises”.
New brake pads or linings
New brake pads and brake discs have to be “bro-
ken in”, and therefore only attain optimal friction
when the car has covered several hundred miles
or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced.
