Two car keys are supplied with your Porsche.
These keys operate all the locks on your vehicle.
f Be careful with your car keys: do not part with
them except under exceptional circumstances.
f To avoid battery run-down, always remove the
ignition key from the ignition lock. Emergency operationfPlease see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 74.
Replacement keys Replacement car keys can be obtained only from
your authorized Porsche dealer, and this can
sometimes be very time-consuming.
You should therefore always keep a spare key on
your person.
Keep it in a safe place (e.g. wallet), but under no
circumstances in or on the vehicle.
The key codes of new keys have to be “reported”
to the car control unit by your authorized Porsche
dealer.
A total of 6 car keys can be reported to the control
unit.
Disabling key codes
If a key is lost, the key codes can be disabled by
an authorized Porsche dealer.
All the remaining car keys are required for this pur-
pose.
Disabling the code ensures that the car can be
started only using authorized keys.
Note
f Please note that the other locks can still be
opened with the disabled key.
Immobilizer There is a transponder (an electronic component)
in the key grip, conta ining a stored code.
When the ignition is switch ed on, the ignition lock
checks the code.
The immobilizer can be deactivated and the en-
gine started only using an authorized ignition key.
Switching off the immobilizer
f Insert the ignition key into the ignition lock.
If the ignition is left on for more than 2 minutes
without the engine being started, the immobilizer
is switched on again.
f If this happens, turn the ignition key back to
position 3 (ignition off) before starting the
engine. The immobilizer is switched off again,
and the engine can be started.
f Please see the chapter “IGNITION/STARTER
SWITCH WITH ANTI-THEFT STEERING LOCK”
on Page 72.
Switching on the immobilizer
f Remove ignition key.Security Wheel Bolts fIf wheels have to be removed during a work-
shop visit, do not forget to hand over the sock-
et for the security wheel bolts along with the
car key.

Maintenance, Car Care
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
f The engine compartment of any motor vehicle
is a potentially hazardou s area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution also applies to the entire vehicle.
f O n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
f Ensure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
f Before working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
f Be alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral position
or the PDK selector lever in position P or N . f
In particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.),
jewelry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The engine-compartment blower is mounted in
the engine-compartment.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off, the ignition switched off, and exercise
extreme caution.
f Your Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise ex-
treme caution when working on any part of the
engine while the ignition is on or the engine is
running.
f Always support your car with safety stands if it
is necessary to work under the car.
f When working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine
cannot be started.
Remove the ignition key. f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher in close reach.
f Incomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your
authorized Porsche dealer.
Improper maintenance during the warranty
period may affect your Porsche warranty cov-
erage.
f Supplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
f Some countries require additional tools and
special spare parts to be carried in your vehi-
cle.
Please make enquiries before driving abroad.

B Vehicle load limit
Is the maximum total weight limit specified of
the load (passengers and cargo) for the vehi-
cle. This is the maximum weight of passengers
and cargo that can be loaded into the vehicle.
Please see the chapter “LOADING INFORMA-
TION” on Page 224.
C Tire size for the front axle Check with your authorized Porsche dealer
about the current release status.
D Recommended tire pre ssure 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 par-
tial or complete loss of traction, vehicle
control or stopping ability.
f Reduce speed on wet surface to prevent this. Tire life Tire life depends on vari ous factors, i. e., road
surfaces, traffic and wea ther 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 wear The original equipment tires on your Porsche have
built-in tire wear indicato rs. 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 adja-
cent 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.
Snow tires lose their traction capability when their
tread depth falls below 5/32 in. (4 mm).
In the United States, state laws may govern the
minimum tread depth permissible. Follow all such
laws.

SpacersfUse the spacers only together with wheels and
fastening parts approved by Porsche.
Before having spacers fitted, find out about the
current approval status.
Mounting an emergency spare wheel
If 5 mm spacers are mounted, these must not be
removed to mount an emergency spare wheel.
Fitting snow chains
The use of snow chains is not permitted when
5 mm spacers are mounted.
Caution!
Risk of damage to the wheel housings if the
5 mm spacers are not removed before fitting
snow chains.
f To permit the fitting of snow chains, have the 5 mm spacers removed on all 4 wheels.Note on operation
f
To fit/remove the spacers:
Please consult an authorized Porsche dealer.
f Please see the chapter “CHANGING A WHEEL”
on Page 227.
Removing the spacers
1. Unscrew both countersunk screws (M6x16) on the wheel hub.
2. Remove the spacer.
3. Fasten the brake disc with the short M6x12
countersunk screws, part No.:
900.269.047.09.
Tightening torque 7.5 ftlb. (10 Nm) .
4. For wheel mounting without a spacer, 5 mm
shorter wheel bolts (part No.:
997.361.203.01 ) must be used.
Tightening torque: 96 ftlb. (130 Nm) .
