Problem
Possible causes/consequences and
M
MSolutions The starter motor was exposed to excessively high thermal load.
X Start the engine again (Y page 134).
If the engine still does not start: X Consult a qualified specialist workshop. Vehicles with a petrol
engine:
The engine is not running
smoothly and is misfir-
ing. The engine electronics or a mechanical component of the engine
management system are/is malfunctioning.
X Depress the accelerator pedal only slightly.
Otherwise, non-combusted fuel may get into the catalytic converter
and damage it.
X Have the cause rectified immediately at a qualified specialist work-
shop. The coolant temperature
display is showing more
than 120 †. A display
message may also
appear on the multifunc-
tion display and a warn-
ing tone may sound. The coolant level is too low. The coolant is too hot and the engine is not
being cooled sufficiently.
X Stop as soon as possible and allow the engine and the coolant to
cool down.
X Check the coolant level (Y page 312). Observe the warning notes
as you do so and top up the coolant if necessary. If the coolant level is correct, the engine radiator fan may be faulty. The
coolant is too hot and the engine is not being cooled sufficiently.
X If the coolant temperature is below 120 †, you can continue driving
to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in moun-
tainous terrain and stop-start traffic. DYNAMIC SELECT switch

rior mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lanes, you will also receive a visual and
audible warning. If a risk of side impact is detec-
ted, a course-corrective brake application may
help you avoid a collision. Active Blind Spot
Assist evaluates the free space in the direction
of travel and to the side before making a course- correcting brake application. For this, Active
Blind Spot Assist uses the forward-facing radar
sensors.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to
vehicles:
R overtaking too closely on the side, placing
them in the blind spot area
R if the difference in the speed of approach
and overtaking is too great
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and maintain a safe distance at the side of the vehicle.
Radar sensors
The Active Blind Spot Assist radar sensors are
integrated in the front and rear bumpers and
behind a cover in the radiator trim. Make sure
that the bumpers and the cover in the radiator
trim are free of dirt, ice or slush. The rear sen-
sors must not be covered, e.g. by bicycle racks
or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist might otherwise no longer function prop-
erly. Monitoring range G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance to the side for other traffic or obstacles. At a distance of approximately 0.5 m
;from
the vehicle, Active Blind Spot Assist monitors
the area up to 3.0 m next to =and behind :
your vehicle, as shown in the picture.
The detection of vehicles may be impaired in the
following situations:
R dirt on the sensors or obscured sensors
R poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may detect them too late.
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 driv- ing in the middle of their lane. This may be the
case if vehicles are driving on the inner side of
their lane. 208
Driving systemsDriving and parking

In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R neither give a warning nor intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not function in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R the radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is very narrow and winding
R there are highly variable shade conditions on
the roadway
If no vehicle is detected in the adjacent lane and broken lane markings are detected, no lane-cor-
recting brake application is made.
Warning vibration through the steering
wheel A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for
up to 1.5 seconds. Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to the original lane. G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation. If a lane-correcting brake application occurs,
display :appears on the multifunction display.
The brake application also slightly reduces driv- ing speed.
A lane-correcting brake application can be made
after the car has passed over a lane marking
detected as being solid or broken. Before this, a warning must have been issued by means of
intermittent vibration through the steering
wheel. In addition, a lane with lane markings on
both sides must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can be made only if a vehicle has been detected
in the adjacent lane. Oncoming vehicles, over-
taking vehicles and vehicles in adjacent lanes
can be detected.
A further lane-correcting brake application can
occur only after your vehicle has returned to the original lane.
No lane-correcting brake application occurs in
the following situations:
R you clearly and actively steer, brake or accel-
erate
R you cut the corner on a sharp bend Driving systems
