Practical Tips, Emergency Service
Exercise Extreme Caution when 
Working on your Vehicle 
 Danger!
Ignoring the following instructions may 
cause serious personal injury or death. 
fThe 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 also applies to the entire vehicle. 
fO 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. 
fEnsure 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. 
fBefore 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. 
fBe 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.fIn particular, be very careful to ensure that 
items of clothing (ties, shirt, sleeves etc.), jew-
elry, 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 
on the engine-compartment lid.
The engine-compartment blower 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.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age 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. 
fAlways support your car with safety stands if it 
is necessary to work under the car.
Jacks are not suitable for this kind of work.
fWhen 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.fDo not smoke or allow an open flame around 
the battery or fuel.
Keep a fire extinguisher in close reach. 
fIncomplete or improper servicing may cause 
problems in the operation of the car. If in doubt 
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age. 
fSupplies 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. 
fSome countries require additional tools and 
special spare parts to be carried. 
Please make enquiries before driving abroad.

Fuel qualityYour engine is designed to provide optimum performance and fuel economy using 
unleaded premium fuel with an octane rating of 98 RON (93 CLC or AKI). 
Porsche therefore recommends the use of these fuels in your vehicle. 
Porsche also recognizes that these fuels may not always be available. Be assured that your vehicle 
will operate properly on unleaded premium fuels with octane numbers of at least 95 RON (90 CLC or AKI), 
since the engine’s “Electronic Oktane™ knock control” will adapt the ignition timing, if necessary.
