Operation, Safety fAlways keep feet in the footwell while driving.
Do not put feet on the dashboard or the seat
area. Do not lean against the inside of the door
or outside the window while the vehicle is
moving.
fUsing accessories not approved by Porsche
can cause the weight sensing system to be
impaired.
fDo not squeeze objects, such as the fire extin-
guisher, or first aid kit under the seat.
fOnly have seats removed and installed by an
authorized Porsche dealer so that weight
sensing components will not be damaged.
fGive your passenger all of the information in
this chapter.
Note
Airbag components (e.g. steering wheel, door
lining, seats) may be disassembled only by an
authorized Porsche dealer.
When disposing of a used airbag unit, our safety
instructions must be followed. These instructions
can be obtained at any authorized Porsche dealer.
Function of the airbag systemAirbags are a supplemental safety system. Your
primary protection comes from your safety belts.
The front airbags are triggered during a frontal
collision of sufficient force and direction.
In the event of a side impact of corresponding force, the side airbag on the impact side is
triggered.
The inflation process generates the amount of gas
required to fill the airbags at the necessary
pressure in fractions of a second.
Airbags help to protect the head and upper body,
while simultaneously damping the motion of the
driver and passenger in the impact direction in the
event of a frontal impact or side impact.
In order to help provide protection in severe colli-
sions which can cause death and serious injury,
airbags must inflate extremely rapidly. Such high
speed inflation has a negative but unavoidable
side effect, which is that it can and does cause
injuries, including facial and arm abrasions,
bruising and broken bones. You can help minimize
such injuries by always wearing your safety belts.
There are many types of accidents in which
airbags are not expected to deploy. These include
accidents where the airbags whould provide no
benefit, such as a rear impact against your
vehicle. Other accidents where the airbags are
designed not to deploy are those where the risk of
injury from the airbag deployment could exeed any
protective benefits, such as in low speed
accidents or higher speed accidents where the
vehicle decelerates over a longer time. Since
airbag deployment does not occur in all accidents,
this further emphasizes the need for you and your
passenger to always wear safety belts.Your vehicle is equipped with a crash sensing and
diagnostic module. This module will record the
use of the seat belt restraint system by the driver
and passenger when the airbags and/or belt tensi-
oner work.
Advanced AirbagYour vehicle is equipped with a weight sensing
system for the passenger's seat in accordance
with U.S. Federal Motor Vehicle Safety Standard
208.
Depending on the weight acting on the
passenger's seat, the passenger's airbag will
automatically be switched on and off.
Depending on the angle and force of impact, the
passenger's airbag which is activated will be
triggered during a collision.
Precondition for switching the passenger's airbag
on and off, depending on weight:
– Vehicles equipped with key-operated airbag
deactivation device:
Switch position AUTO.
– Ignition key is inserted.
Improper handling of the weight sensing
system can unintentionally impair switching
the passenger’s airbag off and on.

Operation, Safety
53
Clutch Pedal The clutch pedal must be depressed fully
before the starter will engage.
Warning!
Risk of an accident, resulting in serious
personal injury or death.
fAlways check the movement of the clutch
pedal 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.

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 (arrow).
With the ignition on, the parking brake warning
lights in the instrument panel and on-board

Alcantara fDo not use a leather care product to clean
Alcantara.
For regular care it is sufficient to clean the cover
with a soft brush.
Heavy abrasion or rubbing when cleaning causes
a lasting change in the surface.
Cleaning when lightly soiled
fWet a soft cloth with water or a neutral soap
solution and wipe off the dirt.
Cleaning when heavily soiled
fWet a soft cloth with lukewarm water or
thinned white spirit and dab the dirt from the
outside in. Safety belts If it becomes necessary to clean the belts, you
can use any mild washing agent.

B Vehicle load limit
Is the maximum total weight limit specified of
the load (passengers and cargo) for the
vehicle. This is the maximum weight of passen-
gers and cargo that can be loaded into the
vehicle.
Please see the chapter “LOADING INFORMA-
TION” on Page 195.
C Tire size for the front axle
Check with your authorized Porsche dealer
about the current release status.
D Recommended tire pressure for the front axle
These values are for cold tires (68 °F/20 °C).
E Tire size for the rear axle
Check with your authorized Porsche dealer
about the current release status.
F Recommended tire pressure for the rear axle.
These values are for cold tires (68 °F/20 °C).
G In vehicles with collapsible spare wheel:
Size and tire pressure of the spare wheel.
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may build up between the
tires and the road. This phenomenon is
known as “hydroplane” and may cause
partial or complete loss of traction, vehicle
control or stopping ability.
fReduce speed on wet surface to prevent this. Tire life Tire life depends on various factors, i. e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
fInspect your tires for wear and damage before
driving off. If you notice uneven or substantial
wear, wheels might need alignment or tires
should be balanced or replaced.
Tire wear The original equipment tires on your Porsche have
built-in tire wear indicators. They are molded into
the bottom of the tread grooves and will appear as
approximately 1/2 in. (12 mm) bands when the
tire tread depth is down to 1/16 of an in.
(1.6 mm).
When the indicators appear in two or more
adjacent grooves, it is time to replace the tires.
We recommend, however, that you do not let the
tires wear down to this extent.
Worn tires cannot grip the road surface properly
and are even less effective on wet roads.
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

Tire and rim sizesExtensive tests are performed before specific tires and wheels are approved by Porsche. Your Porsche dealer has informa-
tion about approved tires and wheels and is happy to assist you.
If aftermarket tires and/or wheels are installed which are not approved by Porsche, the vehicle’s driveability, stability while
in motion and handling characteristics might be impaired. Since Porsche has no data on such combinations, Porsche cannot
stand behind the safety or durability of these aftermarket combinations.
Danger!
Installation of sizes not authorized by
Porsche may have a dangerous effect on
the driving stability and could result in
severe personal injury or death.
fBefore mounting new tires, check with your Porsche dealer about the current release status.
