Seats, Mirrors and Steering Wheel 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 to be impaired.
fDo not squeeze objects, such as the fire
extinguisher, 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, seats)
may be disassembled only by an authorized
Porsche dealer.
fWhen 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 in-
juries, including facial and arm abrasions, bruising
and broken bones. You can help minimize such in-
juries 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 would provide no be-
nefit, 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 exceed any pro-
tective benefits, such as in low speed accidents or higher speed accidents where the vehicle decele-
rates over a longer time. Since airbag deployment
does not occur in all accidents, this further em-
phasizes the need for you and your passengers 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 front passenger when the airbags and/or belt
tentioner are triggered.
Precondition for activating the restraint systems:
fIgnition is switched on.
Advanced AirbagYour vehicle is equipped with weight sensing for
the passenger's seat in accordance with
U.S. Federal/Canadian 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 switched-on will be
triggered during a collision.
Precondition for switching the passenger's airbag
on and off, depending on weight:
fIgnition is switched on.

Correct tire pressure.
Functional description of Tire Pressure
MonitoringTire Pressure Monitoring continuously monitors
tire pressure and tire temperature on all four
wheels and warns the driver when the tire
pressure is too low.The display as well as the settings for Tire
Pressure Monitoring take place on the multi-
purpose display in the sub-menu
TYRE PRESSURE.
However, the tire pressure must still be set
manually on the wheel.
The deviations in the tire pressures from the
required pressures are shown in the sub-menu
TYRE PRESSURE.
Example:
If the tire pressure display shows “–4 psi
(–0.3 bar)”, you must increase the tire pressure by
4 psi (0.3 bar).
The tire pressures to be monitored are fixed in the
Tire Pressure Monitoring system and cannot be
changed.
The following settings must be made to permit
correct monitoring.
–Tires
Select the type and size of the tires fitted on
the vehicle.
–Load
Select the type of loading.
Note on operation
Settings can be made only when the vehicle is
stationary.
fFor information on tires and wheels:
Please see the chapter “TIRES/WHEELS” on
Page 281.
Warning!
Your vehicle has also been equipped with a TPM
malfunction indicator to indicate when the system
is not operating properly.
The TPM malfunction indicator is combined with
the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended.
TPM malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPM from functioning properly.
Always check the TPM malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate
tires and wheels allow the TPM to continue to
function properly.Warning light

Notes on minor repairsTool kit
The tool kit is accommodated in the spare-wheel
well under the cover of the loadspace floor.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids, folding
wedges) are only supplied with the vehicle if the
vehicle comes with a collapsible spare wheel or
full-size spare wheel as standard. Your authorized
Porsche dealer will be pleased to advise you.
Tires/WheelsThe original equipment tires and wheel rims on
your Porsche comply with all applicable Federal
Motor Vehicle Safety Standards.For your safety remember the following:– Wheel rims and wheel bolts are matched to fit
your Porsche.
– If you intend to use other than original equip-
ment wheels, be sure that they conform to
Porsche specifications for your model. Only
tires with the same make and with the same
specification code (e.g. “N0”, “N1”...) can be
mounted.
– The use of wheel rims and wheel bolts that do
not meet specifications of the original factory
installed equipment will affect the safe opera-
tion of your vehicle and affect warranty
coverage.
– Before you plan on exchanging wheels, or
snow tires already mounted on the wheel rims,
consult your authorized Porsche dealer.
Your dealer has the technical information
necessary to advise you which wheel rims and
wheel bolts are compatible with the original
factory installations.
Danger!
Risk of loss of control and serious personal
injury or death.
fIf while driving, your vehicle experiences a sud-
den vibration or ride disturbance, and/or you
suspect that possible damage to your tires or
vehicle has occurred, you should immediately
reduce your speed without excessive use of
the brakes.
fStop the vehicle as soon as possible, and
inspect the tires.
If you cannot determine the cause for the
disturbance, have your vehicle towed to the
nearest Porsche or tire dealer to have your
vehicle or tire(s) inspected.
fContinuing to operate the vehicle without
correction could result in a loss of control and serious personal injury.
