cause damage to the drive train or the
brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. DSR (Downhill Speed Regulation)
You will find information about driving off-
road in the "Operation" section
(Y page 188).
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
set on the on-board computer (Y page 109).
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
non-existent. G
Risk of accident
DSR is only an aid designed to assist you when
driving downhill. You are responsible for keep-
ing control of the vehicle and for assessing
whether the downhill gradient can be man-
aged.
When activating DSR the vehicle may brake
suddenly due to DSR intervening. This is
dependent on the downhill gradient and the
difference between the current speed and the
speed set. DSR may not always be able to
keep to the set speed, depending on road sur-
face and tyre conditions. You could lose con-
trol of the vehicle and cause an accident.
Select a set speed suitable for the prevailing
conditions and when necessary, apply the
brakes manually.
DSR controls the vehicle’s speed when
DIRECT SELECT lever positions D,Rand Nare
selected. You can drive at a higher or a lower speed than that set on the on-board computer
at any time by braking or accelerating. G
Risk of accident
If you depress the accelerator pedal with DSR
activated, then the set speed can be excee-
ded. Drive downhill with special care and
always keep in mind that DSR brakes the vehi-
cle as soon as you remove your foot from the
accelerator pedal. The vehicle may be heavily
braked by DSR depending on the gradient and
the difference between the vehicle's road
speed and the set speed. You could lose con-
trol of the vehicle and cause an accident.
The speed is set to 6 km/h at the factory.
Activating/deactivating DSR Activating
You can only activate DSR when driving at a
speeds below 30 km/h.

any time. For safety reasons, the differential
locks disengage automatically at speeds
above 50 km/h. If you stop the vehicle and
switch off the ignition for longer than ten sec-
onds, the differential locks switch back to
automatic mode.

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control, Distronic *and Speedtronic,
which are used to control the speed of the
vehicle
R Adaptive damping system (ADS), for indi-
vidual adjustment of suspension tuning R
level control, for individual adjustment of
ground clearance
R PARKTRONIC*, which assists you in park-
ing and manoeuvring
R reversing camera*, which assists you when
parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP ®
,
EBV and 4ETS driving safety systems and the
distance warning function* are described in
the "Driving safety systems" section
(Y page 49). Cruise control
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. Driving systems

Permanent Speedtronic is deactivated.
R A limit speed between 240 km/hand
160 km/h in increments of 10 km/h. ADS (Adaptive Damping System)
ADS adapts the damping characteristics to
the current operating and driving situation.
How this is adjusted depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the key from the ignition lock. You can choose between the following ADS
settings:
R
AUTO for normal driving situations; indica-
tor lamps ;and =are off.
R SPORT for sporty driving; indicator
lamp ;is on. In comparison to AUTOor
COMF, the vehicle is 15 mm lower.
R COMF for a more comfortable ride; indica-
tor lamp =is on.
X Start the engine.
X Press button :repeatedly until the
desired setting is selected. Level control
The level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
When you are driving in ADS COMForAUTO
ADS (Ypage 129), the vehicle is lowered to
the high-speed level as the speed increases.
As the vehicle decelerates, the vehicle is
raised back up to highway level.
In ADS SPORT (Ypage 129), the vehicle skips
highway level and is lowered directly to high-
speed level.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as pos-
sible.
The vehicle level may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in tem-
perature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load dis-
crepancies while still parked. However, for
significant level changes, e.g. after the vehi-
cle has been stationary for a long period, the
engine must be on. For safety reasons, the
vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened and continues when the door has
been closed. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you begin
a level change. You could otherwise trap your-
self or others. G
Risk of accident
Always select as low a vehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tipping over. Driving systems

Adapt your driving style to suit the vehicle
level. ESP ®
cannot reduce the risk of an acci-
dent if you drive too fast. ESP ®
cannot over-
ride the laws of physics.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure there is always sufficient ground
clearance to prevent damage to the vehi-
cle.
You will find information about driving off-
road in the "Operation" section
(Y page 188).
Basic settings The extent to which the vehicle is raised or
lowered depends on the basic setting selec-
ted.
Select:
R Off-road level 3 for freeing the vehicle in
impassable terrain at low speeds only
R Off-road level 2 for driving on normal off-
road terrain
R Off-road level 1 for driving on easily nego-
tiable off-road terrain
R Highway/high-speed level for normal roads
The individual vehicle levels are:
R Off-road level 3: 90 mm above highway
level
R Off-road level 2: 60 mm above highway
level
R Off-road level 1: 30 mm above highway
level
R Highway level: +/- 0 mm
R High-speed level: 15 mm below highway
level Off-road levels G
Risk of accident
Off-road level 3 is not permitted for use on
public roads. Off-road level 3 gives your vehi-
cle a very high centre of gravity. This increa-
ses the risk of the vehicle tipping over.
R Only select off-road level 3 for driving off-
road in particularly rough terrain.
R Adjust your driving style to the altered han-
dling characteristics.
R Do not drive faster than 20 km/h.
R Avoid sudden major steering movements.
R Take account of the altered handling char-
acteristics.
If you are driving too fast in off-road level 3,
the Bring speed below 20 km/h message
appears in the multi-function display. You
additionally hear a warning tone. The vehicle
is lowered.
i You cannot clear these messages.
Only select an off-road level when this is
appropriate for the road conditions. Other-
wise, fuel consumption increases and han-
dling performance may be affected.
Your selection remains stored even if you
remove the key from the ignition lock. 130

road menu (Y
page 102) in the on-board com-
puter, the message disappears after about
five seconds.
The vehicle automatically selects highway
level if you are driving at a speed above
115 km/h or if you drive at between
100 km/h and 115 km/h for around 20 sec-
onds. Depending on the ADS basic setting
(Y page 129), the vehicle is lowered to high-
speed level at high speeds. PARKTRONIC*
G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid
using ultrasound. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
R shift the automatic transmission to D,Ror
N
PARKTRONIC is deactivated at speeds above
18 km/h. It is reactivated at lower speeds.
