Controls, Safety, Instruments
Dear Porsche OwnerA lot has gone into the manufacture of your
Porsche, including advanced engineering, rigid
quality control and demanding inspections. These
engineering and safety features will be enhanced
by you...the safe driver...– who knows his car and all controls,
– who maintains the vehicle properly,
– who uses driving skills wisely and always
drives within her/his own capabilities and the
level of familiarity with the vehicle.
You will find helpful hints in this manual on how to
perform most of the checks listed on the following
pages. If in doubt, have these checks performed
by your authorized Porsche dealer.
Before driving off...Check the following items firstfTurn the engine off before you attempt any
checks or repairs on the vehicle.
fBe sure the tires are inflated correctly.
Check tires for damage and tire wear.
fSee that wheel bolts are properly tightened
and not loose or missing.
fCheck engine oil level, add if necessary. Make
it a habit to have engine oil checked with every
fuel filling.
fCheck all fluid levels such as windshield wash-
er and brake fluid levels.
fBe sure the vehicle battery is well charged and
cranks the engine properly.
fCheck all doors and lids for proper operation
and latch them properly.
fCheck and if necessary replace worn or
cracked wiper blades.
fSee that all windows are clear and unobstruct-
ed.
fCheck air intake slots and area between en-
gine compartment lid and windshield are free
of snow and ice, so the heater and the wind-
shield wipers work properly.fIf a child will be riding in the vehicle, check
child seat/child seat restraint system to ensure
that restraints are properly adjusted.
fCheck all exterior and interior lights for opera-
tion and that the lenses are clean.
fCheck the headlights for proper aim, and if
necessary, have them adjusted.
fCheck under the vehicle for leaks.
fBe sure all luggage is stowed securely.
Emergency equipmentIt is good practice to carry emergency equipment
in your vehicle.
Some of the items you should have are: window
scraper, snow brush, container or bag of sand or
salt, emergency light, small shovel, first-aid kit,
etc.

Safety Belts
Danger!
Always make sure your and your passengers'
safety belts are properly fastened while the
vehicle is in motion.
Failure to follow safety belt warnings may re-
sult in serious personal injury or death.
fFor your and your passengers' protection, use
safety belts at all times while the vehicle is in
motion.
fUse appropriate child restraint systems for all
small children.
Proper wearing of safety belts
fSafety belts must be positioned on the body as
to restrain the upper body and lap from sliding
forward. Improperly positioned safety belts
can cause serious personal injury in case of an
accident.
fThe shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fFor maximum effectiveness, the lap belt
should be worn low across the hips.
fPregnant women should position the belt as
low as possible across the pelvis. Make sure it
is not pressing against the abdomen.
fBelts should not be worn twisted.fDo not wear belts over rigid or breakable ob-
jects in or on your clothing, such as eye glas-
ses, pens, keys, etc. as these may cause inju-
ry.
fSeveral layers of heavy clothing may interfere
with proper positioning of belts.
fBelts must not rub against sharp objects or
damage may occur to the belt.
fTwo occupants should never share the same
belt at the same time.
Care and maintenance
fKeep belt buckles free of any obstruction that
may prevent a secure locking.
fBelts that have been subjected to excessive
stretch forces in an accident must be inspect-
ed or replaced to ensure their continued effec-
tiveness in restraining you.
The same applies to belt tensioner systems
which have been triggered. In addition, the an-
chor points of the belts should be checked.
fIf safety belts do not work properly, see your
authorized Porsche dealer immediately.
fI f t h e b e l t s s h o w d a m a g e t o w e b b i n g , b i n d i n g s ,
buckles or retractors, they should be replaced
to ensure safe operation.
fDo not modify or disassemble the safety belts
in your vehicle.fThe belts must be kept clean or the retractors
may not work properly.
Please observe the chapter “CAR CARE IN-
STRUCTIONS” on Page 265.
fNever bleach or dye safety belts.
fDo not allow safety belts to retract until they
are completely dry after cleaning or this may
cause damage to the belt.

Controls, Safety, Instruments
Fastening the safety beltfAssume a comfortable sitting position.
Adjust the backrest of the front seat so that the
belt always rests on your upper body and runs
across the middle of your shoulder.
fGrasp the belt tongue and pull the belt in a
slow, continuous motion across your chest and
lap.
Note on operation
The belt can be blocked if the vehicle is standing
at an angle or if the belt is pulled out using a jerk-
ing movement.fThe belt cannot be pulled out while accelerat-
ing and slowing down, when cornering and
when driving uphill.
fInsert the belt tongue into the appropriate
buckle on the inboard side of the seat, until it
locks securely with an audible click.
fMake sure that belts are not trapped or twist-
ed, and that they are not rubbing on sharp edg-
es.
fThe horizontal section of the belt should al-
ways fit snugly across the pelvis. Therefore, af-
ter fastening the belt, always pull the diagonal
part of the belt upwards.
Pregnant women should position the belt as
low as possible across the pelvis, and ensure
that it is not pressing against the abdomen.
fPull on the diagonal section of the belt now and
again during the journey to ensure that the
horizontal section remains tight.fMake sure that the belts and buckles fit
correctly on the rear seat bench.

Automatic locking retractorThe safety belts for the passenger and rear seats
are equipped with an automatic locking retractor
for securing the child restraint system. When acti-
vated, this retractor allows you to securely fasten
the child restraint system in place so that inadvert-
ent movements will not occur.

1. Pull the safety belt retractor completely out. At
this point the locking mechanism is activated.
2. Insert the safety belt tongue into the buckle
and make certain that it is properly latched.
3. 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.
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.

Child Restraint SystemsPorsche 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.
The use of infant or child restraints is required by
law in all 50 states and the Canadian provinces.
The child restraint system should be one that com-
plies with U.S. Federal/Canadian Motor Vehicle
Safety Standards 213 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
(LowerAnchorage 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!
Risk of serious personal injury or death to the
child.
fFollow 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 they 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.
– For maximum safety and protection, do not
use a child restraint system in the front passen-
ger seat.
Danger!
The use of a child restraint system in the
front passenger seat can result in serious
personal injury or death to the child from an
airbag deployment.
To reduce risk of injury from an inflating air-
bag in an accident, Porsche strongly recom-
mends:
fDo not use a child restraint system in the front passenger seat.
fSeek appropriate advice from your authorized
Porsche dealer about the possible installation
of a Porsche child restraint system.
Rearward facing child restraint system:
fUse only in the rear seat. Must not ever be
used in the front seat.
Forward facing child restraint system:
fUse only in the rear seat. Must not ever be
used in the front seat.

48
Controls, Safety, Instruments Use only child restraint systems with the LATCH
system recommended by Porsche.
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-compatible at your authorized Porsche
dealer.
fAlways observe the separate installation in-
structions for your child seat.
Installing an LATCH child seat systemMarkings on the right and left for the LATCH child
seat anchorage can be found on the backrests of
the outer rear seats.
The anchor bars A for the LATCH child seat
anchorage can be found directly under the
markings between backrest and seat cushion.
Danger!
The use of a child restraint system in the
front passenger seat can result in serious
personal injury or death to the child from an

Parking BrakeThe parking brake acts on the rear wheels and
serves to secure the car while parked.
fUse the parking brake only after the vehicle
has come to a full stop.
Applying the parking brakefPress down firmly on the foot pedal.
The warning light in the instrument panel lights
up.
A message will be displayed on the multi-pur-
pose display of the instrument panel if the
parking brake is not released before moving
off.
If the brake is not fully set, the vehicle may roll
without control.
fBefore exiting the vehicle, make sure that the
parking brake is fully applied and the vehicle is
not moving at all.
Danger!
Risk of serious personal injury or death. A
partially engaged parking brake may allow

Brake pedal
Warning!
Risk of an accident.
Any obstruction of the brake pedal could in-
crease 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
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 boosterThe 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, road salt or grit on brakes affects brak-
ing. When the vehicle is driven on salted or gritted
roads for extended periods, the brakes should be
washed down thoroughly about every 2 weeks. An
automatic carwash facility cannot do this job prop-
erly. Brakes will dry after a few cautious brake ap-
plications.
Warning!
Driving through water may reduce the trac-
tion. Moisture on brakes from road water, car
wash, or a coating of road salt or grit may af-
fect braking efficiency.
fCautiously apply brakes to test brakes after being exposed.
