ted to a limited degree and the drive wheels can
spin. The spinning wheels produce a cutting
effect for better traction. ABS, ESP ®

LOW RANGE offroad gear (vehicles with
the Offroad Engineering 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 accelera-
tor 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 dan-
ger 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. General notes
 C
LOW RANGE offroad gear button  D
LOW RANGE offroad gear indicator lamp
HIGH RANGE
Position for all normal on-
road driving conditions
LOW RANGE
Offroad position for driving
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 posi-
tion. Drive torque is thus
proportionately higher.
Do not use LOW RANGE: R
on slippery road surfaces,
e.g. in the case of slush R
on snow or ice-covered
roads R
if you have mounted snow
chains to your vehicle
The LOW RANGE offroad gear assists you in
driving off-road and when fording. When LOW
RANGE is engaged, the engine’s performance
characteristics and the gearshifting character-
istics of the automatic transmission are adapted
for this purpose.

Snow chains
G WARNING
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: R
never install snow chains to the front
wheels R
always install snow chains in pairs to the
rear wheels.
! You must drive at raised vehicle level (height
1) if snow chains have been installed. The
vehicle may otherwise be damaged.
! Vehicles with ADS (Adaptive Damping
System): do not use the sport mode when
driving with snow chains mounted. The vehi-
cle may otherwise be damaged.
! On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" 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 workshop.
If you intend to mount snow chains, please bear
the following points in mind: R
Only use snow chains when driving on roads
completely covered by snow. Remove the snow chains as soon as possible when you
come to a road that is not snow-covered. R
do not exceed the maximum permissible
speed of 30 mph (50 km/h). R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
you wish to mount snow chains. R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations ( Y
page 413).
You may wish to deactivate ESP ®
when pulling
away with snow chains installed ( Y
page 72).
You can thereby allow the wheels to spin in a
controlled manner, achieving an increased driv-
ing force (cutting action).

spare wheel ( Y

Tire pressure
Tire pressure specifications
Important safety notes
G WARNING
Underinflated or overinflated tires pose the
following risks: R
the tires may burst, especially as the load
and vehicle speed increase. R
the tires may wear excessively and/or
unevenly, which may greatly impair tire
traction. R
the driving characteristics, as well as steer-
ing and braking, may be greatly impaired.
There is a risk of an accident.
Follow recommended tire inflation pressures
and check the pressure of all the tires includ-
ing the spare wheel: R
monthly, at least R
if the load changes R
before beginning a long journey R
under different operating conditions, e.g.
off-road driving
If necessary, correct the tire pressure.
The data on the Tire and Loading Information
placard and tire pressure table shown here are390
Tire pressure
Wheels and tires 

Information on the message display can be
found in the "Restarting the tire pressure loss
warning system" section ( Y
page 394).
Important safety notes The tire pressure warning system does not warn
you of an incorrectly set tire pressure. Observe
the notes on the recommended tire pressure
( Y
page 390).
The tire pressure loss warning does not replace
the need to regularly check the tire pressure. An
even loss of pressure on several tires at the
same time cannot be detected by the tire pres-
sure loss warning system.
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
movements.
The function of the tire pressure loss warning
system is limited or delayed if: R
snow chains are mounted on your vehicle's
tires. R
road conditions are wintry. R
you are driving on sand or gravel. R
you adopt a very sporty driving style (corner-
ing at high speeds or driving with high rates of
acceleration). R
you are driving with a heavy load (in the vehi-
cle or on the roof).
Restarting the tire pressure loss warn-
ing system Restart the tire pressure loss warning system if
you have: R
changed the tire pressure R
changed the wheels or tires R
mounted new wheels or tires X
Before restarting, make sure that the tire
pressures are set properly on all four tires for
the respective operating conditions.
The recommended tire pressure can be found
on the Tire and Loading Information placard
on the B-pillar. Additionally, a tire pressure
table is attached to 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. X
Also observe the notes in the section on tire
pressures ( Y
page 390). X
Make sure that the SmartKey is in position 2
in the ignition lock ( Y
page 145).X

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 pressure mon-
itor 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 of
driving, the current tire pressure of each tire is394
