WARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle. G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again. The brake lamps are not illuminated when you
brake the vehicle using the parking brake.
As a rule, you may only apply the parking
brake when the vehicle is stationary. X
To apply the parking brake: pull brake
lever 0043up as far as the last possible
detent.
The 0066 warning lamp in the instrument
cluster lights up if the engine is running.
i On vehicles with a folding brake lever, you
can then press lever 0043down to the stop.
X To release the parking brake: on vehicles
with a folding brake lever, first pull brake
lever 0043up to the stop.
X Raise brake lever 0043slightly and press
release knob 0044.
X Guide brake lever 0043down to the stop.
The 0066 indicator lamp in the instrument
cluster goes out.
Exceptionally, if the service brake fails, the
parking brake can be used to brake the vehi-
cle in an emergency.
X Emergency braking: press and hold
release button 0044and carefully apply brake
lever 0043. Switching off the engine
G
WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is a risk of
an accident.
After switching off the engine, always switch
to parking position P. Prevent the parked vehi-
cle from rolling away by applying the parking
brake.
! If the coolant temperature is very high,
e.g. after driving on hilly roads, leave the
engine running at idle speed for about
two minutes before turning it off.
This allows the coolant temperature to
return to normal.
X Stop the vehicle.
X Shift the automatic transmission to posi-
tion P. 152

Setting the speed It may be a moment before the vehicle starts
to accelerate or brake to the set speed. Take
this delay into account when setting the
speed.
X Briefly push the cruise control lever
upwards 0043to increase the speed or down-

Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 11.5 ft (3.5 m) to each side of
it. For this purpose, Blind Spot Assist uses
radar sensors in the rear bumper and behind
the protective strips of the B-pillars.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R a clear warning situation may not occur.
The yellow indicator lamp on the relevant
side of the vehicle will then light up.
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, for
example trucks, for a prolonged time.
The four sensors of Blind Spot Assist are inte-
grated into the rear bumper and behind the
protective strips of the B-pillars. Make sure
that the bumper and protective stripping are
free of dirt, ice or slush in the vicinity of the
sensors. The radar sensors must not be cov-
ered, for example by cycle racks or overhang-
ing loads. Have the function of the radar sensors
checked at a qualified specialist workshop:
R
after a severe impact
R in the event of damage to the bumper
R in the event of damage to the protective
strips of the B-pillars
Blind Spot Assist may otherwise not work
properly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated. 0043

R there is no clear warning, depending on the
situation
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in
the blind spot monitoring range, red warning
lamp 0043on the corresponding side lights up.
This warning occurs when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 14 mph (22 km/h).
Yellow indicator lamp 0043goes out if reverse
gear is engaged. Blind Spot Assist is then

Towing a trailer
If you attach a trailer, make sure that you have
correctly established the electrical connec-
tion. This can be accomplished by checking
the trailer lighting. Blind Spot Assist is then

Lane Keeping Assist General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of a camera at
the top of the windshield. Lane Keeping Assist
detects lane markings on the road and warns
you before you leave your lane unintention-
ally.
0043
Lane Keeping Assist camera
Lane Keeping Assist supports you from
speeds of approximately 40 mph(60 km/h).
Important safety notes G
WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
R give an unnecessary warning
R not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist. G
WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There
is a risk of an accident. 166
Driving systemsDriving and parking
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
Lane Keeping Assist may not work properly
or may not work at all if the vehicle is incor-
rectly loaded (Y page 242).
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Lane
Keeping Assist is only an aid. You are respon-
sible for the distance to the vehicle in front,
for vehicle speed, braking in good time and
for staying in your lane.
Lane Keeping Assist does not keep your vehi-
cle in its lane.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no, or several, unclear lane markings are
present for one lane, e.g. in a construction
area
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are highly variable shade conditions
on the road
A warning may be given if a front wheel
passes over a lane marking. In addition, a warning tone sounds and the
00B0indicator
lamp in the instrument cluster lights up.
