when accelerating or when applying the brakes or when driving
around a corner.
• When you are driving make sure that anything you may have
placed in the center console or other storage locations cannot fall
out into the footwells. In case of sudden braking you would not be
able to brake or accelerate.

Stopping the engine
-Turn the ignition key to position @::::} page 119, fig. 132.
& 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. •

& WARNING (continued)
• The brake booster and the servotronic only work when the

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
t he engine. Let the vehicl e stand and run in idl e for about 2 minutes

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
indicator light in the instrument cluster (U.S. models:=., Canadian

& 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

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
city, in stop-and-go traffic , on twisting roads and when road
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.

& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake. This is because
the cruise control is overridden by the driver's acceleration.

& WARNING
Following other vehicles too closely increase s the risk of a crash
and ser ious personal injury.
• Following other vehicles too closely, particularly at higher
speeds inc reases the r isk of collisions and serious personal injury.
• Setting short distances to the traffic ahead redu ce s the time
and d istance available to br ing your vehicle to a safe stop and
make s it even more ne ce ss ary to pay clo se attention to traffi c.
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffi c, road, weather and

• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Contr ol may not be able to
