Working on components in the engine
compartment
Extra caution is necessary when working on components
in the engine compartment.
Always be aware of the danger of injury and scalding as well as the
risk of accident or fire when working in the engine compartment
(e.g. when checking and refilling fluids). Always observe the warn-

engine compartment of any motor vehicle is a potentially
hazardous area. ⇒

WARNING
Switch off the engine.
Remove the ignition key.
Apply the parking brake.
Move the gear lever into neutral.
Wait for the engine to cool down.
Keep children away from engine compartment.
Never spill fluids on hot engine components. These fluids can
cause a fire (e.g. radiator anti-freeze).
Take care not to cause short circuits in the electrical system,
especially when working on the battery.
Do not touch the radiator fan when the engine is hot. The fan
may start running suddenly.
Do not unscrew the cap on the expansion tank when the engine
is hot. The cooling system is under pressure.
Protect face, hands and arms by covering the cap with a large,
thick rag to protect against escaping coolant and steam.
If any tests have to be performed with the engine running,
there is an extra safety risk from the rotating parts, such as the
drive belts, alternator and radiator fan, etc., and from the high-
voltage ignition system.
