suddenly fall into the closed position. There
is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one
is within its range of movement.
GWARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING

Rswitch off the ignition
Rnever reach into the area where there is a
risk of danger from moving components,
such as the fan rotation area
Rremove jewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from moving parts

The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning productsto remove brake dust. This could damagewheel bolts and brake components.
!Do not park your vehicle for a long periodof time directly after cleaning, particularlyafter cleaning the wheel rim with wheelcleaner. Wheel cleaner can lead to theincreased corrosion of the brake discs andpads. Therefore, drive for a few minutesafter cleaning. By heating up the brakes, thebrake discs and pads dry. The vehicle canthen be parked for a long period of time.
