& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running. With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats up because of intense sunlight or heat build-up in the engine
compartment.
0 Note
Do not stop the engine immediate ly after hard or extended driving .
Keep the engine running for approximately two minutes to prevent
excessive heat build-up. •

required to steer or brake the vehicle. If you are not prepared, this
could result in a collision and serious personal injury.
• For your safety, move the selector lever to the P position, then
turn off the engine. Otherwise the vehicle could inadvertently roll
away.
• After turning off the engine, the radiator fan can come on and
run for up to 10 minutes -even if the ignition is switched off. Like­
wise, the fan could come on if the temperature in the engine
compartment raises due to heat build up or if you leave the vehicle
standing in direct sunlight.
0 Note
After driving at high engine load, heat can build up in the engine
compartment after you have turned off the engine. This can damage

electromechanical parking brake provides various convenience and
safety functions.
Emergency brake
An emergency brake ensures that the vehicle can be slowed even if
the normal brakes fail~ page 125, "Emergency braking".

Indicator lights
•
If the parking brake is applied with the ignition turned on, the
indicator light in the instrument cluster (U.S. models:=.., Canadian
models: ©) and in the switch
«el) will come on.
• If the parking brake is applied with the ignition turned off, the

& WARNING
If the vehicle is stationary and the transmission is engaged with
the engine running, the engine should not be speeded up (e.g.
manually from under the hood). Otherwise the vehicle will start to
move -you run the risk of an accident.
0 Note
If the warning/indicator light (U.S . models: BRAKE, Canadian models:

[ i] Tips
• You can apply the parking brake at any time -even with the igni­
tion turned off . The ignition must be turned on in order to release the
parking brake.
• Occasional noises when the parking brake is applied and released
are normal and are not a cause for concern.

& WARNING
• Alway s pay attention to traffic even when the cruise control i s
switched on. You are always responsible for your speed and the
di stan ce between your vehicle and other vehicles.
• For safety r easons , the cruise control should not be used in the

conditions are poor ( such as ice , fog, gravel, heavy rain and hydro­
planing ) -risk of accident .
• Turn off the cruise control temporarily when enter ing turn
lanes , highway exit lane s or in construction zone s.

_________________________________________________ O_ n_t_ h _ e_ ro_ a_d __ ffllll
& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­

S mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e.g. if you want to pass someone. The speed you saved earlier will
resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by S mph (10 km/h) for
longer than S minutes, the cruise control will turn off temporarily .
