Using child restraint systems in the
passenger seat
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 de-
ployment.
To reduce risk of injury from an inflating air-
bag in an accident, Porsche strongly recom-
mends:
fPlease observe the chapter “PASSENGER
AIRBAG OFF INDICATOR LAMP DOES NOT
LIGHT UP” on Page 47.
fPlease observe the chapter “CHILD RES-TRAINT SYSTEMS” on Page 49.Child restraint system for up to one-year old
children
– Make sure that the PASSENGER AIRBAG OFF
indicator lamp lights up.
– Adjust the passenger's seat as far away from
the airbag as possible.
Danger!
Risk of serious personal injury or death due
to the passenger’s airbag triggering uninten-
tionally.
When the ignition is on and the up to one-
year old child is seated in the child restraint
system on the passenger’s seat the indicator
lamp „PASSENGER AIRBAG OFF“ must be on.
If the “PASSENGER AIRBAG OFF” indicator
lamp does not light up, it could indicate a
fault in the system.
In this case:
fDo not use a child restraint system on the pas-
senger’s seat.
fOn vehicles with key-operated airbag deactiva-
tion device: Switch to position OFF.
fHave the fault remedied at your nearest author-ized Porsche dealer.Child restraint system for children older than
one year
Your vehicle is equipped with a weight sensing sys-
tem for the passenger's seat in accordance with
U.S. Federal Motor Vehicle Safety Standard 208.
Depending on the weight acting on the passen-
ger's seat, the passenger's airbag will automati-
cally be switched on or off.
Small adult passengers
Make sure that the PASSENGER AIRBAG OFF indi-
cator lamp does not light up.
Danger!
Risk of serious personal injury or death due
to the passenger’s airbag not triggering.
When the ignition is on and the small adult
passenger is seated on the passenger’s seat,
the indicator lamp “PASSENGER AIRBAG
OFF” must be off.
If the “PASSENGER AIRBAG OFF” indicator
lamp lights up, it could indicate a fault in the
system.
In this case:
fDo not carry a passenger in the passenger’s
seat.
fHave the fault remedied at the nearest author-ized Porsche dealer.

Automatic locking retractorThe 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’s
seat:

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.
fAfter fastening the child restraint system, do
not adjust the seat.
fCheck the condition of the passenger’s airbag
system shown by the indicator lamp A in the central console.Activating the automatic locking retractor
1. If a child restraint system must be fastened to
the passenger's seat, adjust the passenger's
seat as far away from the airbag as possible.
2. Fasten child seat.
3. Pull the safety belt retractor completely out. At
this point the locking mechanism is activated.
4. Insert the safety belt tongue into the buckle
and make certain that it is properly latched.
Make no more adjustments to the seat.
5. Allow the safety belt to retract until it is tight on
the child restraint system. You may further
tighten the belt by pulling on it to allow more of
it to retract.
Make sure that excessive seat belt forces do
not occur by moving the seat with the child
seat installed.
Releasing the safety belt
1. Unbuckle the safety belt latch.
2. Then make certain that the belt has fully re-
tracted. At this point the automatic locking fea-
ture will be disengaged.
Seek appropriate advice from your authorized
Porsche dealer about the possible installation
of a Porsche child restraint system.

LATCH SystemChild seat bracket on the passenger’s
seatThe key switch for switching off the passenger’s
airbag and the LATCH attachment bracket are not
installed at the factory. They can be retrofitted.
fPlease see your authorized Porsche dealer.
Porsche recommends the use of a Porsche Child
Seat with Lower Anchorage and Tether for Chil-
dren system (LATCH).
These systems have been tested and adjusted to
the interior of your Porsche and the appropriate
child age groups. Other systems have not been
tested and could entail an increased risk of injury.
You can obtain child seats that are LATCH compat-
ible at your authorized Porsche dealer.
fAlways observe the separate installation in-
structions for your child seat.
fPlease observe the chapter “CHILD
RESTRAINT SYSTEMS” on Page 49.
Installing a LATCH child seat system1. Secure the child seat to retaining lugs A as
outlined in the instruction manual for the child
seat.
2. Pull the child seat to check that both fastening
points are engaged correctly.
Note
Make sure that the key switch is switched to AUTO
once the child seat has been removed, in order to
provide protection to the adult occupants.

Child Restraint AnchoragefPlease observe the chapter “AUTOMATIC LO-
CKING RETRACTOR” on Page 52.
If your child restraint seat requires the use of a
tether strap, you will want to use the anchor point
behind the passenger’s seat under the carpet.
fTo ensure proper installation, see your author-
ized Porsche dealer.Note
If a child seat with top tether is adapted for use on
the passenger’s seat, the anchor point must be
used for anchoring the top tether.
Warning!
The child restraint anchorage is designed to
withstand only the load imposed by a cor-
rectly fitted child restraint. Under no circum-
stances is the anchorage to be used for adult
safety belt or harness. Such use could result
in serious injury or death.
fDo not misuse the child restraint anchorage.
This is not designed to withstand a load im-posed by an adult.

Clutch Pedal The clutch pedal must be depressed fully be-
fore the starter will engage.
Warning!
Risk of an accident.
fAlways 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.
fSecure 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:
fAlways depress the clutch pedal fully when
changing gears.
fDo 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 mean a malfunction of the
clutch.
fSee your Porsche dealer for correction.
Parking Brake Parking brake force is mechanically transferred to
the rear wheels by means of cables.
fUse the parking brake only after the vehicle
has come to a full stop.
Setting the parking brake fPull the lever all the way up (see arrow).
With the ignition on, the parking brake warning
lights in the instrument 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.
fMove the selector lever to “P” (Tiptronic) or
move the gearshift lever to reverse or first
gear (Manual transmission).
fBefore exiting the vehicle, make sure that the
parking brake is fully set 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, causing serious personal
injury or death to any person in its path.
fEngage the parking brake fully.Releasing the parking brake fPull the lever slightly up as you depress the re-
lease button, and then push the lever all the
way down.

56
Controls, Instruments The parking brake warning lights 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 driv-
ing the car. Caution!
A partially engaged brake will overheat the
rear brakes, reduce their effectiveness and
cause excessive wear.
fRelease the parking brake fully.
fWhen parking your car, always set the parking
brake by pulling all the way up on the lever.
fMove the selector lever to “P” (Tiptronic) or
move the gearshift lever to reverse or first
gear (Manual transmission).
fOn hills also turn the front wheels towards the
curb.
Brakes fMake it a habit to check 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.
fTherefore, always maintain a safe distance
from the car in front of you.
Vehicles without Porsche Ceramic
Composite 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.
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.
In the unlikely event of hydraulic failure of
one brake circuit:
fPush 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.
fAfter 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.

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" to
1-9/16" 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.
Any obstruction of the pedal could increase
the stopping distance.
fAlways check the movement of the brake pedal
before driving and make sure that it is not ob-
structed by a floor mat or any other object.
fSecure 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
floor mats of the correct size including a secur-ing possibility.
Note
In case one of the two brake circuits fails, in-
creased pedal travel is required to bring your vehi-
cle to a full stop.
Warning!
To avoid overheating and premature wear of
the brakes:
fBefore descending a steep grade, reduce
speed and shift the transmission into a lower
gear or driving position to control speed.
fDo not ride the “brakes” by resting your foot on
the pedal when not intending to apply brake
pressure.
fDo not hold the pedal down too long or too of-
ten.
This could cause the brakes to get hot and not function properly.

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 booster is defective, more
pressure on the brake pedal is required to bring
the car to a stop.
Moisture or road salt on brakes affects braking.
When the vehicle is driven on salted roads for ex-
tended periods, the brakes should be washed
down thoroughly about every 2 weeks. An auto-
matic carwash facility cannot do this job properly.
Brakes will dry after a few cautious brake applica-
tions.
Warning!
Driving through water may reduce traction.
Moisture on brakes from road water, car
wash, or coating of road salt may affect
braking efficiency.
fCautiously apply brakes to test brakes after being exposed.
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.
fHave the brake system inspected at the inter-
vals recommended in your Maintenance Book-
let.
If the lights in the instrument panel and on-board
computer stay on when the engine is running or
come on while driving, the brake pads are worn,
excessively.
fDo not continue to operate the vehicle.
Have your authorized Porsche dealer inspect
or replace the brake pads.
Brake pads Wear 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 the brakes to squeal.
New brake pads or linings
New brake pads have to be “broken in”, and there-
fore 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.

ABS Brake System
(Antilock Brake System) The ABS system represents a major contribution
to the enhancement of active safety in your vehi-
cle. This system prevents the wheels from locking
in a panic stop on almost all road surfaces. With the ABS system in your vehicle, the fol-
lowing areas are enhanced:
Steering, vehicle remains steerable under all
braking forces when ABS is engaged.
Good directional control, no swerving caused
by locking of wheels under braking conditions.
Shorter stopping distance, stopping distances
are usually reduced because controlled braking is
maximized.
Prevention of wheel lock up, no brake- induced
sliding and thus no localized tire wear from emer-
gency braking.
The crucial advantage of the ABS system over a
conventional brake system is in the area of main-
taining directional control and maneuverability of
the car in emergency situations during normal driv-
ing, including panic braking in turns.
Warning!
The increased control that is provided should
not induce you to take greater risks with your
safety. The limits dictated by the laws of
physics cannot be overcome, even with ABS.
The risk of accidents due to inappropriate
speed cannot be reduced, even by the ABS.
The driver bears the responsibility for all
driving maneuvers.
fAdapt your driving style to the prevailing road
and weather conditions.
fObey all traffic laws.
Other vehicles not equipped with the ABS
system may not be able to maintain control,
especially on wet or poor road surfaces and
thus may be more likely to impact you from
behind.
fTo minimize that risk, use your ABS system to
increase your ability to maneuver to avoid dan-
gerous situations and not merely to try to stop in the shortest distance possible.

Controls, Instruments
Operation of the ABS system A wheel speed sensor is mounted to each of the
four wheels. If wheel lock-up of either of the front
wheels or the rear wheels is sensed during brak-
ing, the brake pressure is adjusted automatically
until the wheel no longer slips. The brake pressure
is regulated for each front wheel individually and
for both of the rear wheels together.
On a road surface which is slippery on only one
side, the rear wheel which is braking on the slip-
pery surface determines the brake pressure which
will be applied equally to both rear wheels. This en-
sures that directional stability is maintained. How-
ever, if braking forces approach the wheel lock-up
point for all wheels (panic braking) the ABS system
will intervene to provide a rapid rhythmic braking.
The proper operation of ABS is perceived by the
driver as a pulsating brake pedal in conjunction
with audible noise and perhaps some vibration.
fIf you experience these sensations while driv-
ing or a road surface with questionable trac-
tion, reduce vehicle speed appropriate for the
prevailing road conditions.
The functional readiness of all the main electrical
components of the ABS is checked by an electron-
ic monitoring system both before and while you
drive. When the ignition is switched on the ABS warning
light will light up while the system is electronically
interrogated and goes out 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.
fIf the ABS system becomes inoperative, take
your vehicle to your authorized Porsche dealer
immediately.
Warning!
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 the vehicle, because of
the variant data it receives from the sensors
on the axles.
fUse only tire makes and types tested by Porsche.
