!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.
iIn 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
GWARNING
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
XPress button
:.
Indicator lamp ;lights up.
The à DSR symbol appears in the mul-
tifunction display.
You can only activate DSR when driving at
speeds at or below 28 mph (40 km/h).
If the current vehicle speed is too high, the
à DSR symbol appears in the multifunc-
tion display with the Max. Speed 28 mph
message (Canada:40 km/h).
If you have activated DSR and you change the drive program, DSR is deactivated. If you
switch between the Offroad and Offroad Plus
drive programs, DSR remains activated.

tion display with the Off
message. The status
indicator in the multifunction display goes
out. You also hear a warning. On vehicles with
the ON&OFFROAD package, if you select a
different on-road/off-road program, DSR is
also deactivated.
Changing the set speed
XTo increase or decrease in 1 mph incre- ments (Canada: 1 km/h increments):
briefly press the cruise control lever up :
for a higher set speed or down ;for a
lower set speed.
The set speed appears in the multifunction
display with the ÃDSR symbol.
When DSR is activated, you can change the
set speed to a value between 1 mph and
11 mph (Canada: between 2 km/h and
18 km/h).
iThe DSR set speed is always changed in
1 mph increments (Canada: 1 km/h incre-
ments). This is regardless of whether you
press the cruise control lever to or beyond
the pressure point.
Off-road programs (vehicles with the
ON&OFFROAD package)
General notes
The off-road programs assist you in driving
off-road. The engine's performance charac-
teristics and the gearshifting characteristics
of the automatic transmission are adapted for
this purpose. ABS, ESP
®and 4ETS programs
especially adapted to off-road driving are acti- vated. An accelerator pedal curve suitable for
the terrain is selected, i.e. the accelerator
pedal must be depressed further to acceler-
ate.
Do not use the off-road programs on roads
that are snow-covered or icy or if you have
mounted snow chains on your vehicle.
For information on driving off-road, see
(
Ypage 198).
The following program messages are shown
in the multifunction display until the applica-
ble vehicle level is set. Up to off-road level 2,
you can hide the program messages using the
% or the abutton on the multifunction
steering wheel.

Driving and parking

Only winter tires bearing theisnowflake
symbol in addition to the M+S marking pro-
vide the best possible grip in wintry road con-
ditions. Only these tires will allow driving
safety systems such as ABS and ESP
®to
function optimally in winter. These tires have
been developed specifically for driving in
snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling charac-
teristics.
Always observe the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
XCheck the tire pressures (Ypage 411).
XRestart the tire pressure monitor
(
Ypage 412).
XVehicles for Canada: restart the tire pres-
sure loss warning system (
Ypage 412).

Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
!You must drive at raised vehicle level
(height 1) if snow chains have been instal-
led. The vehicle may otherwise be dam-
aged.
!Vehicles with Adaptive Damping Sys-
tem (ADS): do not use the sports mode if you have installed snow chains. The vehicle
may otherwise be damaged.
!On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality. For more information,
please contact a qualified specialist work-
shop.
If you intend to mount snow chains, please
bear the following points in mind:
ROnly use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as possi-
ble when you come to a road that is not
snow-covered.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
RLocal regulations may restrict the use of
snow chains. Observe the appropriate reg-
ulations if you wish to mount snow chains.
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (
Ypage 432).
You may wish to deactivate ESP
®when pull-
ing away with snow chains installed
(
Ypage 74). You can thereby allow the wheels
to spin in a controlled manner, achieving an
increased driving force (cutting action).

The tire pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tire is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditions are wintry.
Ryou are driving on sand or gravel.
Ryou adopt a very sporty driving style (cor-
nering at high speeds or driving with high
rates of acceleration).
Ryou are towing a very heavy or large trailer.
Ryou are driving with a heavy load (in the
vehicle or on the roof).
Restarting the tire pressure loss warn-
ing system
Restart the tire pressure loss warning system
if you have:
Rchanged the tire pressure
Rchanged the wheels or tires
Rmounted new wheels or tires
XBefore restarting, make sure that the tire
pressures are set properly on all four tires
for the respective operating conditions.
The recommended tire pressures can be
found on the Tire and Loading Information
placard on the B-pillar on the driver's side
or the tire pressure table on the fuel filler
flap.
The tire pressure loss warning system can
only give reliable warnings if you have set
the correct tire pressure. If an incorrect tire
pressure is set, these incorrect values will
be monitored.
XAlso observe the notes in the section on tire
pressures (
Ypage 408).
XMake sure that the SmartKey is in position

Tire pressure monitor
General notes
If a tire pressure monitor is installed, the vehi-
cle's wheels have sensors that monitor the
tire pressures in all four tires. The tire pres-
sure monitor warns you if the pressure drops
in one or more of the tires. The tire pressure
monitor only functions if the corresponding
sensors are installed in all wheels.
Information on tire pressures is displayed in
the multifunction display. After a few minutes
