Function of the air bag systemAir bags are a supplemental safety system. Your
primary protection comes from your safety belts.
The front air bags are triggered during a frontal
collision of sufficient force and direction.
In the event of a side impact of corresponding
force, the side air bag on the impact side is
triggered.
The inflation process generates the amount of gas
required to fill the air bags at the necessary
pressure in fractions of a second.
Air bags help to protect the head and 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
collisions which can cause death and serious
injury, air bags 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 air
bags are not expected to deploy. These include
accidents where the air bags would provide no
benefit, such as a rear impact against your
vehicle. Other accidents where the air bags are
designed not to deploy are those where the risk of
injury from the air bag deployment could exceed any protective benefits, such as in low speed
accidents or higher speed accidents where the
vehicle decelerates over a longer time. Since air
bag deployment does not occur in all accidents,
this further emphasizes 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 air bags and/or belt
tentioner are triggered.
Precondition for activating the restraint systems:
f
Ignition is switched on.
Advanced air bagYour vehicle is equipped with occupant sensing for
the passenger's seat in accordance with
U.S. Federal Motor Vehicle Safety Standard 208.
Depending on the weight, body positioning and
shape acting on the passenger's seat, the
passenger's air bag will automatically be switched
on and off.
Depending on the angle and force of impact, the
passenger's air bag which is switched-on will be
triggered during a collision.
Precondition for switching the passenger's air bag
on and off, depending on weight, body positioning
and shape:
fIgnition is switched on.
Danger!
Risk of serious personal injury or death due
to the passenger air bag not triggering.
Improper handling of occupant sensing can
unintentionally impair switching the
passenger's air bag off and on.
If the weight on the passenger's seat is
reduced significantly, e.g., by supporting
weight on the armrest, the passenger's air
bag can be switched off.
f Select an upright seat position, and do not
support weight on the armrests or lean out of
the window.
Always 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.
f If a child restraint system is installed on the passenger’s seat, do not adjust the seat.

Danger!
Risk of serious personal injury or death to the
child.
f Follow all child restraint instructions and warnings in this manual.
– When using an infant or child restraint system, be sure to follow all manufacturer's
instructions on installation and use.
– Infants and small children should neither 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 must use regular safety belts. A shoulder belt
can be used providing it does not cross the
face or the neck of the child.
– Choose a child restraint system according to the age and size of the child.
– Child restraint systems that are damaged or have been heavily stressed in an accident must
be replaced immediately.
– Children could be endangered in a crash if their child restraints are not properly secured in
vehicle.
– Do not affix objects to child restraint systems or cover them with other materials.
f For maximum safety and protection, do not
use a child restraint system in the front
passenger seat.
Direction of installation for child restraint
systemsAccording to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Under all normal circumstances, the child seat
must be placed in the rear.
fDo not use a child restraint system in the front
passenger seat.
Group 0 and 0+: Children up to 29 lbs
(13 kg)
Children of this weight must be transported in a
restraint system which is fitted facing
backwards .
Group I: Children in between 20 lbs (9 kg)
and 40 lbs (18 kg)
Children of this weight are transported in child
restraint systems facing forward.
Group II: Children in between 33 lbs (15 kg)
and 55 lbs (25 kg)
Children of this weight are transported in child
restraint systems facing forward.
Group III: Children in between 49 lbs (22 kg)
and 80 lbs (36 kg)
Children of this weight are transported in child
restraint systems facing forward.
Using child restraint systems in the front
passenger 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
air bag deployment.
To reduce risk of injury from an inflating air
bag in an accident, Porsche strongly
recommends:
f Under all normal circumstances, the child seat
must be placed in the rear.
Do not use a child restrai nt system in the front passenger seat.
However, there may be se rious situations where it
might be necessary to pl ace a child in the front
seat so that he/she can be kept under direct
observation to prevent an immediate risk to the
child (for example, while driving to the doctor or
hospital). The following in structions are provided
to you solely for that purpose.
f Seek appropriate advice from your authorized
Porsche dealer about the possible installation
of a Porsche child restraint system.
f If a child restraint system must be fastened to
the passenger's seat, adjust the passenger's
seat as far away from the air bag as possible.

(type and size of fitted tire)
Warning!
Risk of accident due to excessive speed. This
could lead to serious personal injury or
death.
f Always observe the permissible maximum
speed of the respective tire.
f Exceeding maximum tire speed could result in
a tire burst, causing loss of control of the
vehicle. This could lead to serious personal
injury or death.
Moreover, Porsche recommends obeying all
traffic laws at all times to maintain the safety of yourself and all vehicle occupants. Warning!
Incomplete entries or selection of the wrong
tires on the multi-function display affect
correct indication of warnings and
messages.
f The settings must be updated in the “Tire
pressure ” menu after changing a wheel, filling
with tire sealant or adding air (after previous
warning “ Tire pressure!”).
f Please see the chapter “RED WARNING – TIRE PRESSURE!” on page 133. The new tire type and tire
size must be selected
even if the settings for the new set of wheels are
the same as for the old wheels.
Available setting options:
–“ 18 inch ”
–“ 19 inch ”
–“ 20 inch ”
Tire selection has only been successfully
completed when the following message appears
on the multi-function display (example).
“Summer tires 19-inch was set. No monitoring,
system is learning”.
f Please see the chapter “SYSTEM LEARNING”
on page 134. Notes
The message “Action cancelled” appears if the
setting process is interrupted. All entries made up
to this point are lost, and the original settings
remain in effect.
Before fitting tires with dimensions that are not
already stored in the mult
i-function display, the
missing information should be added to the
multi-function display.
f Please contact a qualified specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools.
f Use only tires approved by Porsche.
The available items in the tire pressure menu
depend on the model type. For this reason it is
possible that some of the selection options shown
here are not available on your multi-function
display.

Example of a tire pressure plateTire Pressure plateInformation on the tire pressure plate
A Seating capacityMaximum number of vehicle occupants,
including the driver.
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
passengers and cargo that can be loaded into
the vehicle.
Please see the chapter “LOADING
INFORMATION” on page 236. C Original tire size
Size of tires mounted at the factory.
D Recommended cold tire inflation pressure These values are for cold tires (68 °F/20 °C).
Tire traction
Warning!
When driving on wet or slushy roads, a
wedge of water may bu ild 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.
f Reduce speed on wet surfaces to prevent this.
Tire lifeTire life depends on various factors, i.e., road
surfaces, traffic and weather conditions, driving
habits, type of tires and tire care.
f Inspect 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 wearThe 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.

Minor Repairs
Snow chains
Warning!
Risk of damage to body, axle or brake
components.
f Use only the fine-link snow chains recom-
mended and authorized by Porsche so that
sufficient clearance between the wheel well
and the chain is assured.
f Please see the chapter “WHEELS, TIRES” on
page 325.
f Follow instructions issued by the supplier of the chains.
Fit snow chains only on the rear axle.
f Remove spacers if snow chains are mounted.
f Before fitting chains, remove accumulated ice
and snow from the wheel well.
f Vehicles with snow chains must not be driven
faster than 30 mph (50 km/h) .
Different states and countr ies have varying statu-
tory requirements regarding maximum speed.
f Check with local authorities for possible
restrictions.
f Remove chains as soon as the roads are free
of ice and snow.
