take account of road, weather and traffic con-
ditions. 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 lane.
If a drive wheel spins due to insufficient grip:
R when pulling away, only depress the accel-
erator pedal as far as is necessary.
R accelerate less when driving.
! 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 implied 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.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. DSR
Important safety notes i
DSR (Downhill Speed Regulation) is only
available for vehicles with the Off-Road
Engineering package.
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The
steeper the downhill gradient, the greater the
DSR braking effect on the vehicle. When driv-
ing on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
non-existent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D, Ror N. By accelerating or braking, you can
always drive at a higher or a lower speed than
that set on the on-board computer.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor over-
ride the laws of physics. DSR cannot take account of road, weather and traffic condi-
tions. 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 lane.
You are always responsible for keeping con-
trol 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 surface and tyre
conditions. Select a set speed suitable for theprevailing conditions and when necessary,
apply the brakes manually. G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
For information about driving off-road, see
(Y page 185).
Activating/deactivating DSR G
WARNING
If you drive faster than the set speed and acti-
vate DSR, the vehicle will decelerate on down- hill gradients. If you do not know the set
speed, the vehicle could decelerate unexpect-edly. There is a risk of an accident.
Decelerate the vehicle to the set speed before
activating DSR. If you do not know what the
stored set speed is, store the desired set
speed again.
Activating
You can only activate DSR when driving at
speeds below 30 km/h. 204

Problems with PARKTRONIC
Problem
Possible causes/consequences and
M
MSolutions Only the red segments
in the PARKTRONIC
warning displays are lit.
You also hear a warning
tone for approximately
two seconds.
PARKTRONIC is then
deactivated and the
indicator lamp on the
PARKTRONIC button
lights up. PARKTRONIC has malfunctioned and has been deactivated.
X If problems persist, have PARKTRONIC checked at a qualified
specialist workshop. Only the red segments
in the PARKTRONIC
warning displays are lit.
PARKTRONIC is then
deactivated. The PARKTRONIC sensors are dirty or there is interference.
X Clean the PARKTRONIC sensors (Y page 326).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X See if PARKTRONIC functions in a different location. Active Parking Assist
General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when exit-
ing a parking space. You may also use PARK- TRONIC (Y page 206).
i The active braking application is only
available on vehicles with automatic trans- mission.
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate surroundings. The responsibility for safe
manoeuvring and parking remains with you. Make sure that no persons, animals or
objects are in the manoeuvring range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres. 210
Driving systemsDriving and parking

Active Parking Assist is activated automati-
cally when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde- pendently locates and measures parking
spaces on both sides of the vehicle.
Active Parking Assist will only detect parkingspaces:
R that are parallel or at right angles to the
direction of travel
R that are parallel to the direction of travel
and are at least 1.5 m wide
R that are parallel to the direction of travel
and at least 1.0 mlonger than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 m wider than your
vehicle
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 30 km/h, you
will see parking symbol ;as a status indi-
cator in the instrument cluster. When a park-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand- ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. When parking on the driver's side, this must remain switched on
until you acknowledge the use of Active Park-
ing Assist by pressing the abutton on the
multifunction steering wheel. The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.

the voltage supply.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected.
R the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.

Parking tips: R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. It may be the case that Active
Parking Assist guides you too far into a Driving systems
213Driving and parking Z
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the kerb. If necessary, you should can-
cel the parking procedure with Active Park- ing Assist.
R You can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should a gear be changed too early, the parking pro- cedure will be cancelled. A sensible parking
position can no longer be achieved from
this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space:
R the border of the parking space must be
high enough. A kerb stone is too small, for
example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is manoeuvred into the park-
ing space.
R a manoeuvring distance of at least 1.0 m
must be available.
i Vehicles with automatic transmission:
If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst
the vehicle exits the parking space. You are responsible for braking in good time.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the vehicle parallel to the direction of travel using Active Parking Assist.
