Automatic locking retractorfDo not install a child restraint system in
the Sports bucket seat.
The Sports bucket seat cannot be
equipped with the LATCH system.
The safety belt for the passenger is equipped with
an automatic locking retractor for securing the
child restraint system. When activated, this retrac-
tor allows you to securely fasten the child restraint
system in place so that inadvertent movements
will not occur.
Before transporting a child on the passenger seat:
f Please see the chapter “CHILD RESTRAINT
SYSTEMS” on Page 50.
Danger!
Risk of serious personal injury or death to the
child, when excessive force is acting on the
passenger's seat due to the seat belt.
In such cases, the passenger's airbag can be
switched on unintentionally.
f After fastening the child restraint system, do
not adjust the seat.
f Check the condition of the passenger’s airbag
shown by the indicator lamp in the central con-sole. Activating the automatic locking retractor

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.

Operation, Safety
When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes o
ut when the engine is
started if the check is not yet complete.
If the ABS warning lamp fails to go out, this indi-
cates that ABS has been deactivated due to a
fault. If the warning lights in the instrument panel
and on-board computer light up while you are driv-
ing, this indicates that a fault has occurred. In both
cases, normal braking, as in vehicles without ABS,
is still retained.
The ABS system should, however, be examined at
an authorized Porsche dealer immediately to pre-
vent the occurrence of further faults.
f If the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
The control unit of the ABS brake system is
set for standard tire size. If non-standard
tires are installed, the control unit may mis-
interpret the speed of th e vehicle, because of
the variant data it rece ives from the sensors
on the axles.
f Use only tire makes and types tested by Porsche.
Clutch Pedal The clutch pedal must be depressed fully
before the starter will engage.
Warning!
Risk of an accident, resulting in serious per-
sonal injury or death.
f Always check the movement of the clutch ped-
al before driving and make sure that it is not
obstructed by a floor mat 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.
To avoid damage to the clutch and transmis-
sion:
f Always depress the clutch pedal fully when
changing gears.
f Do not hold the car on a steep grade with the clutch pedal partially depressed.
Should the free travel of the clutch pedal suddenly
become larger, it could me an a malfunction of the
clutch.
f See your Porsche dealer for correction.

Sport ModeA sportier car set-up is obtained when Sport mode
is switched on. Interventions by the Porsche
control systems are intentionally shifted towards
greater agility and driving performance:
– PASM (Porsche Active Suspension Manage-ment) is automatically changed to Sport mode,
resulting in a stiffer suspension setup.
– When Sport mode is active, the PDK transmis- sion switches to a sporty gear-changing map
and shortens the gear shifting times. Gear
changes take place faster, but fuel consump-
tion is also increased.
PSM (Porsche Stability Management) control
gives a sportier road-feel to the vehicle. PSM
interventions take place later than in Normal
mode. The driver can maneuver the vehicle
with greater agility at its performance limits,
without having to dispense with the assistance
of PSM in emergency situations. This helps to
achieve optimal lap times, particularly on race
circuits with a dry road surface.
– The electronic accelerator pedal reacts sooner, and the engine is more responsive to
throttle inputs. When Sport mode is switched
on, this function is ac tivated only after the
driver has floored the accelerator pedal or
released it briefly.
– The rpm limiter characteristic is “harder”, i.e. the engine is immediately throttled when the
performance limits are reached (only in manual selection mode for vehicles with PDK transmis-
sion).
f Please observe the chap ters on PSM, PASM
and PDK.
Switching Sport mode on and offSwitching Sport mode on and off simultaneously
activates and deactivate s the Sport mode in
PA S M .
If PASM Sport mode was activated with the PASM
button, PASM remains active.
After the ignition is switched off, Sport mode is
automatically reset to Normal mode.
