Driving and Driving Safety
f
Do not warm up the engine when stationary.
Drive off immediately. Avoid high revs and full
throttle until the engine has reached operating
temperature.
f If the vehicle battery power is too weak, the
engine can be started with jump leads.
For information on jump-lead starting:
f Please see the chapter “EXTERNAL POWER
SUPPLY, JUMP-LEAD STARTING” on
page 306.
Note on operation
To ensure a good battery charge condition,
thereby ensuring that the battery will start the
engine, all electrical loads that are not required
should be switched off when the ignition is
switched on and when engine revs are low
(in traffic jams, in city traffic or in queues).
Stoppingf Only remove the ignition key when the vehicle
is stationary.
f Only switch the ignition off when the vehicle is
stationary, as there is no power steering and
brake booster assistance when the engine is
switched off.
f When leaving the vehicle, always remove the
ignition key, apply the electric parking brake
and engage selector-lever position P .
The control unit always remains in the ignition
lock on vehicles with Porsche Entry & Drive .
Warning!
Danger of injury. Hot engine compartment
components can burn skin on contact.
f Before working on any part in the engine
compartment, turn the engine off and let it cool
down sufficiently.
Risk of burn injury when standing near or
coming into contact with the exhaust pipe.
The exhaust pipe is hot wh en the vehicle is running
and remains hot for some time after the vehicle is
turned off. f
To prevent injury, make a point of noting where
your vehicle’s exhaust pipe is, avoid placing
your legs near the exhaust pipe when loading
and unloading cargo in the rear, and closely
supervise children around the vehicle during
time when the exhaust pipe could be hot.
A hot exhaust pipe can cause painful skin
burns.
Radiator fanFor information on radiator fans:
f Please see the chapter “RADIATOR FANS” on
page 258.
Warning!
Danger of injury. After the ignition is
switched off, the engine compartment and
coolant temperatures are monitored for
approx. 30 minutes. During this period, and
depending on temperature, the radiator fan
may continue to run or start to run.
f Carry out work in these areas only with the
engine off and exercise extreme caution,
always anticipating that the fan blade could suddenly start to run.

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.
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
cautious of devices such as hot water heaters
which ignite a flame intermittently.
f Before working on any part in the engine
compartment, 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 the engine at all
times while it is running. If you have to work on
the engine while it is running, always put the
parking brake on and put 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 fan, belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
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
engine off and exercise extreme caution.
f Your Porsche is equipped with an electronic
ignition system. When the ignition is on, high
voltage is present in all wires connected with
the ignition system; therefore, exercise
extreme 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. The jack
supplied with the car is not adequate for this
purpose.
Switch off level control of air suspension and
height adjustment.
Please see the chapter “RAISING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 290.
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.
Withdraw ignition keys (switch ignition off in
vehicles that have Porsche Entry & Drive). f
Do not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
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
coverage.
f Supplies of fluids, e.g. engine oil, washer fluid,
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
appropriate regulations.
f Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.

Technical ModificationsfModifications may be carried out on your
vehicle only if approved by Porsche.
This ensures that your Porsche will remain
reliable and safe to drive, and that it will not be
damaged as a result of the modifications.
Your authorized Porsche dealer will be pleased
to advise you.
Safety notes!
f Only use genuine Porsche spare parts for your
vehicle or spare parts of similar quality which
have been manufactured according to the
specifications and production requirements of
Porsche. These parts are available from your
authorized Porsche dealer or a qualified
specialist workshop. Safety-related
accessories should only be used if they are
from the Porsche Tequipment range or are
tested and approved by Porsche. Your
authorized Porsche dealer will be pleased to
advise you and answer any questions you may
have.
However, the use of other parts or
accessories may adversel y affect the safety
of your vehicle, and Porsche can take no
responsibility for any loss or damage caused
by their use.
Even if the supplier of other accessories or
parts is a recognized supplier, the safety of
your vehicle may still be affected if such items
are installed.
Due to the large variety of products offered in the accessory market, it is not possible for
Porsche to inspect and approve every one.
f In addition, please note that the use of
replacement parts that are not genuine
Porsche parts or approved parts, or the use of
accessories not approved by Porsche may
also detrimentally affect your vehicle warranty.
f Check your vehicle regularly for signs of
damage. Damaged or missing aerodynamic
components, such as spoilers or underbody
panels, impair vehicle handling and must
therefore be replaced immediately.

Maintenance and Car Care
1. If the engine is hot, cover the reservoir cap
with a cloth.
Open cap carefully and allow any overpressure
to escape.
Then unscrew cap completely.
2. Read off the engine coolant level. Top up with coolant if necessary.
Only add a mixture of antifreeze and water
in equal parts.
Antifreeze in coolant:
50 % provides antifreeze protection
down to –31 °F (–35 °C).
Do not top up over the plus marking.
3. Screw the cap on the reservoir closed until it locks securely.
4. Have the cooling system checked. Please contact a qualif ied 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. Maintenance notes
If pure water is added in an emergency, the mixing
ratio will have to be corrected.
A significant loss of coolan
t indicates a leak in the
cooling system.
f The cause must be eliminated without delay.
Please contact a qualified specialist workshop.

f Exercise extreme care when working close to
the radiator fans and make sure the engine is switched off.
Brake FluidRegular checking of the brake fluid is part of
servicing.
The fluid level should always be between the
MIN and MAX markings.
A slight decrease in the fluid level due to wear
and automatic readjustment of the disc brakes
is normal.
However, if the fluid level falls significantly or
goes below the MIN marking, the brake system
may have developed a leak.
fHave the brake system checked immediately.
