! A function or performance test should
only be carried out on a two-axle dyna-
mometer. 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.
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.

DSR (Downhill Speed Regulation) General notes
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
nonexistent.
DSR controls the vehicle’s speed when it is
activated and the transmission is in position
D , R or N . You can drive at a higher or a lower
speed than that set on the on-board computer
at any time by accelerating or braking.
Important safety notes
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. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
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 your 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 tire
conditions. Select a set speed suitable for the
prevailing conditions and when necessary,
apply the brakes manually.
Activating DSR

Press button C .
Indicator lamp D lights up.
The

Off-road level 1 is set to +1.2 in (+30 mm)
above the vehicle's "highway" level.
Off-road program 1 switches to the AUTO
program if you drive faster than 70 mph
(110 km/h).
Select off-road program 1 for gentle off-road
terrain, e.g. for gravel or sand surfaces or
tracks. The engine's torque is restricted to a
limited degree and the drive wheels can spin.
The spinning wheels produce a cutting effect
for better traction.
You can only activate off-road program 1
when driving at speeds of 60 mph (100 km/h)
or below. The Drive Program OFFROAD 1
Max. 60 mph ( 100 km/h) message appears
in the multifunction display.

road driving conditions
LOW RANGE
Off-road position for driv-
ing off-road and fording
The transmission ratio
between the engine and
wheels is only approx-
imately one third of that in
the HIGH RANGE road
position. Drive torque is
thus proportionately
higher.
Do not use LOW RANGE: R
on slippery road surfa-
ces, e.g. in the case of
slush R

roads R
if you have mounted
snow chains to your
vehicle The LOW RANGE off-road gear assists you in
driving off-road and when fording. When LOW
RANGE is engaged, the engine’s performance
characteristics and the gearshifting charac-
teristics of the automatic transmission are
adapted for this purpose.

driving safety systems in conjunction with
