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.
• Any articles of clothing that you have hung up must not inter­
fere with the driver's view. The coat hooks are designed only for
lightweight clothing . Never hang any clothing with hard, pointed
or heavy objects in the pockets on the coat hooks. During sudden
braking or in an accident -especially if the airbag is deployed -

Stopping the engine
-Turn the ignition key to position®~ page 130, fig. 145.
& 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 immediately after hard or extended driving.
Keep the engine running for approximately two minutes to prevent
excessive heat build-up.•

& WARNING
• Always pay attention to traffic even when the cruise control is
switched on. You are always responsible for your speed and the
distance between your vehicle and other vehicles.
• For safety reasons, the cruise control should not be used in the
city, in stop-and-go traffic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident.
• Turn off the cruise control temporarily when entering turn
lanes, highway exit lanes or in construction zones.

&, 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.
[ i] Tips
The brake lights illumin ate as soon as the brakes decelerate
automatically. •
Changing speed
-Press lever@in the 0 or Q direction=> page 137,
fig. 149 to increase or decrease your speed.
-Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 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 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The green symbol in the
display=> page 137, fig . 150 is replaced
with a white symbol. The saved speed remains the same. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
-Turn on the ignition .
-Pull lever@ into position G) => page 137, fig. 149 .
-Press the lever in the 0 or Q direction to increase or
decrease your speed.
-Release the lever to save that speed.

-Switch the ignition off.
The system retains the saved speed if you deactivate the cruise
control temporarily . To resume the saved speed , release the brake

vehicle in front o f you . A warning tone signal wi ll also sound when
the symbol appears.
[ i ] Tip s
• If the Adaptive Cruise Control initiates braking, the hydraulic
brake system is under pressure. Therefore, the brake pedal distance
is shorter and the peda l feels "harder" .
• I f you use the accelerator to go faster than the speed being main ­
tained by the Adaptive Cruise Control, the system will not warn of
situations that require override of the Adaptive Cruise Control. No
warning light will appear in the instrument cluster display and no gong wil l sound .•

reasons
• If you pu ll the control lever forward to resume speed but no
requested speed was set.
• I f you push the lever up to increase (or down to reduce) speed

this speed is outside the range from 20 to 95 mph !Canada models:

A CC not a vailab le
The text message ACC not av ailabl e appears, for example, if the
temperature of the brakes is excessive . Adaptive Cruise Control is
t emporarily not availab le . A warning tone sounds as a rem inder.
A CC not available !
The text message ACC not av ailabl e! appears in the event of a
malfunction. Adaptive Cruise Control is turned off . A warning tone
sounds as a reminder. Have the system inspected by a qua lified
dea lersh ip.
ACC senso r blocked
The text message AC C s en so r blo cked appears when the ACC
System does not detect any objects over an extended time period .
For the time being, the distance to vehicles up ahead is not being
cont rolled . The ACC system is not switched off, so increased alert ­
ness is required. The following may be reasons for the text message
ACC sensor blocked:
• The ACC sensor is dirty. The ACC system is not react ing, or is not
reacting correctly, to vehic les traveling ahead.
• It is possible that you are driving on a road with very light traffic
without any thing at the side of the road (e.g. guard rai ls, traffic
s igns, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message d isappears .
The ACC sensor is located in the area under the front license plate .
I f there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation.
AC C senso r bl ock ed!
The text message ACC sensor blocked! appears when the ACC
System can no longer guarantee safe detection of objects . Adaptive
cruise control is turned off . A chime sounds as a reminder.
To decide whether it is necessary to switch off t he ACC (ACC sensor
blocked!) or if it is only a temporary condition (ACC sensor blocked),
the system wi ll a lso takes into cons ideration the outside tempera -
ture and/or the windshield wiper operation .
