Maintenance and Car Care 239
Exercise Extreme Caution when
Working on your vehicle
The engine compartment of any motor vehicle is
a potentially hazardous area. If you are not fully
familiar with proper repair procedures, do not
attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
Many vehicle fluids are highly flammable, e.g. fuel,
engine and transmission oil. Fuel vapors can
cause an explosion. When a battery is being
charged, highly explosive gases can develop.
f Do not smoke or allow an open flame around
the battery or fuel.
Pay attention to sparks, e.g. when coming into
contact with cables.
Keep a fire extinguisher close at hand.
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 Only work on your vehicle outdoors or in a well
ventilated area.
Refill fluids, e.g. engine oil, brake fluid or coolant
are hazardous to health (poisonous, irritant,
caustic).
f Keep these fluids out of children's reach and
dispose of them in accordance with the
appropriate regulations.
f Only work on your vehicle outdoors or in a well
ventilated area.
Engine exhaust is dangerous if inhaled.
Engine exhaust fumes have many compo-nents
which you can smell. They also contain carbon
monoxide (CO), which is a colorless and odorless
gas.
Carbon monoxide can cause unconsciousness
and even death if inhaled.
f Only work on your vehicle outdoors or in a well
ventilated area.
The engine and surroundings components, the
exhaust system and coolant become very hot
when the engine is running.
The coolant reservoir is pressurized. Careless
opening of the coolant reservoir can lead to hot
coolant suddenly spraying out.
f Take care when working near hot parts of the
vehicle, in particular engine parts and parts of
the exhaust system.
f Before working in the engine compartment,
always switch the engine off and let it cool
sufficiently.
f Allow the engine to cool down before opening
the cap of the coolant reservoir and protect
your hands, arms and face from any possible
escape of hot coolant.
Take great care to ensure that hands, fingers,
articles of clothing (e.g. ties, sleeves, etc.),
necklaces or long hair cannot be caught up by the
radiator fans, drive belt or other moving parts.
The radiator fans can start or continue running as
a function of temperature, even with the engine
switched off.
f Exercise extreme care that parts of the body,
articles of clothing or jewelry do not get caught
in the radiator fan, drive belt or other moving
parts.
f Carry out work in these areas only with the
engine off and exercise extreme caution.
When the ignition is on, all cables and wires of the
ignition system carry a high voltage.
f Exercise special care when working on the
ignition system.

240 Maintenance and Car Care
If the vehicle is not secured, or incorrectly
secured, during repair work, it could move
unexpectedly or fall from the car jack or car lift.
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 apply the electric parking
brake and put the gearshift lever in neutral or
the Tiptronic selector lever in position P or N.
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 “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM, TROLLEY JACK
OR STANDARD JACK” on page 274.
f Jack up the vehicle only at the specified
jacking points on the underside of the vehicle.
f Never start the engine when the vehicle is
jacked or lifted up. Vibration from the engine
could cause the vehicle to fall.
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).
Information
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 Some countries require additional tools and
special spare parts to be carried in your
vehicle. Please make enquiries before driving
abroad.
Technical Modifications
f Modifications 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.
Information
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 adversely 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.
