250 Maintenance and Car Care

Exercise Extreme Caution when Working on your Vehicle

Danger!

Ignoring the following instructions may cau-se serious personal injury or death.

f 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.

f Only work on your vehicle outdoors or in a well 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 such 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 engine at all times while the engine is running.

If you have to work on the engine while it is running, always put the parking brake on and put the gearshift lever in neutral or the Tiptronic 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.For vehicles with air suspension with level control and height adjustment switch off level control.Please see the chapter “RAISING VEHICLE WITH THE JACK” on Page 192.

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 can-not 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 appro-priate regulations.

f Some countries require additional tools and special spare parts to be carried in your vehicle. Please make enquiries before driving abroad.
