Problems with Night View Assist Plus
Problem Possible causes/consequences and
0001 Solutions
The picture quality of
Night View Assist Plus
has deteriorated. The windshield wipers are smearing the windshield.
X
Replace the wiper blades (Y page 133). The windshield is smeared after the vehicle has been cleaned in a
car wash.
X
Cleant he windshield (Y page 373). There is windshield chip damage in the camera's field of vision.
X
Replace the windshield. The windshield is fogged up on the inside.
X
Defrost the windshield (Y page 150). The windshield is iced up.
X
De-ice the windshield (Y page 149). There is dirt on the inside of the windshield.
X
Cleant he inside of the windshield (Y page 373).Lane Tracking package
General notes The Lane Tracking package consists of Blind
Spot Assist (Y page 233) and Lane Keeping
Assist (Y page 235).
Blind Spot Assist General notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It supports you from a speed of
approximately 20 mph (30 km/h). A warning
display in the exterio rmirrors draws your
attention to vehicles detected in the
monitored area. If you then switch on the
corresponding tur nsignal to change lanes,
you will also receive a visual and audible
collision warning. Blind Spot Assist uses
sensors in the rear bumper for monitoring
purposes. For Blind Spot Assist to assist you when
driving, the radar sensor system must be:
R
activated(Y page 276)
R operational
Important safety notes G
WARNING
Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing the minthe blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.

Adaptive
When
Adaptive is selected, no warning
vibration occurs if:
R you switch on the tur nsignals .Inthis event,
the warnings are suppressed for a certain
period of time.
R a driving safety system intervenes, e.g.
ABS, BAS or ESP ®
.
R you accelerate hard, e.g. kickdown.
R you brake hard.
R you steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
R you cut the corner on a sharp bend.
In order that you are warned only when
necessary and in good time if you cross the
lane marking, the system recognizes certain
conditions and warns you accordingly.
The warning vibration occurs earlier if:
R you approach the outer lane marking on a
bend.
R the road has very wide lanes, e.g. a
highway.
R the system recognizes solid lane markings.
The warning vibration occurs later if:
R the road has narrow lanes.
R you cut the corner on a bend. Active Driving Assistance package
General notes The Active Driving Assistance package
consists of DISTRONIC PLUS (Y
page 194),
Active Blind Spot Assist (Y page 237) and
Active Lane Keeping Assist (Y page 241).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your
vehicle which are behind the driver. Awarning
display in the exterior mirrors draws your
attentio nto vehicles detected in the monitored area. If you then switch on the
corresponding turn signal to change lane, you
will also receive an optical and audible
warning. If a risk of lateral collision is
detected, corrective braking 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 radar sensors which
are pointed in the direction of travel.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be:
R
activated(Y page 276)
R operational
Important safety notes
Active Blind Spot Assist is only an aid. It may
fail to detect some vehicles and is no
substitute for attentive driving. G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always observe the traffic conditions
carefully, and maintain a safe lateral distance.

4MATIC (permanent four-wheel drive) If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! A function or performance test should
only be carried out on atwo-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop .You could otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficien tgrip.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
Further information about "Driving off-road"
(Y page 187).
DSR (Downhill Spee dRegulation) Important safety notes
DSR assists you when driving downhill. It
keeps the speed of travel at the speed set on
the on-board computer. The steeper the
downhill gradient, the greater the DSR
braking effect on the vehicle .When driving on
flat stretches of road or on an uphill gradient,
the DSR braking effect is minimal or
nonexistent.
DSR controls the set speed when it is active
and the automatic transmission is in the D,
R or Nposition. By accelerating or braking,
you can always drive at a higher or a lower
speed than that set on the on-board
computer.
Further information about "Driving off-road"
(Y page 187).
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor
override the laws of physics. DSR cannot take
account of road, weather and traffic
conditions. DSR is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
You are always responsible for keeping
control of the vehicle and for assessing
whether the downhill gradient can be
managed. DSR may not always be able to
keep to the set speed, depending on road 246

with the ON&OFFROAD package) Important safety notes
G
WARNING
If you select the LOW RANGE off-road gear on
a slippery road surface, the wheels could lose
traction:
R if you remove your foot from the
accelerator pedal when driving
R if off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased
danger of skidding and accidents.
Never select the LOW RANGE off-road gear
when driving on slippery road surfaces. G
WARNING
If you do not wait for the transfer case gear
change process to complete, the transfer
case could remain in the neutral position. The
power transmission to the driven wheels is
then interrupted. There is a danger of the
vehicle rolling away unintentionally. There is
a risk of an accident.
Wait until the transfer case shift process is
completed.
Do not turn off the engine while changing gear
and do not shift the automatic transmission
to another position. Driving systems

WARNING
If you install a ball coupling other tha nthe one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in
question is longer or angled differently. This
could seriously impair the driving
characteristics and the trailer can come
loose. There is a risk of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch. G
WARNING
If the ball coupling is not installed correctly or
not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter. G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest.N
ever
depress the brake pedal and the accelerator
pedal at the same time. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The
vehicle/trailer combination could even
rollover. There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer .Apply the
brake as necessary.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
Please observe the manufacturer's operating
instructions for the trailer coupling if a
detachable trailer coupling is used.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
