The vehicle has permanent 4-wheel drive
(4MATIC). Power is always transmitted to
both axles.
! Performance tests may only be carried
out on a 2-axle dynamometer. The brake
system or transfer case could otherwise be
damaged. Contact an authorized
Mercedes-Benz Center for a performance
test. Mercedes-Benz recommends that you
use an authorized Mercedes-Benz Center
for this purpose.
! If the parking brake is being tested on a
brake dynamometer, the ignition must be
switched off (SmartKey or Start/Stop
button in position 0 or 1), as ESP ®
will
otherwise automatically intervene. The test
must last a maximum of 10 seconds. The
brake system could otherwise be damaged.
LOW RANGE off-road gear
The LOW RANGE off-road gear is only
available in vehicles with the Off-Road Pro
Engineering package.
Use the LOW RANGE off-road gear:
R when driving off-road
R when fording
R when towing on uphill or downhill gradients
When LOW RANGE is engaged, the engine’s
performance characteristics and the
gearshifting characteristics of the automatic
transmission are adapted for this purpose. In
addition, ABS, ESP ®
and 4ETS specially
adapted to off-road driving will be activated.

R Select the off-road drive program
( Y page 204).
R Restrict the shift range to 1 or 2.
R Avoid high engine speeds.
R Enter and exit the water at a flat place and
at a steady walking pace.
! Under no circumstances should you
accelerate before entering the water. The
bow wave could cause water to enter and
damage the engine and other assemblies.
R Drive slowly and at an even speed through
the water.
R Do not stop.
! Do not open any of the vehicle's doors
while fording. Otherwise, water could get
into the vehicle interior and damage the
vehicle's electronics and interior
equipment.
R Water offers a high degree of resistance,
and the ground is slippery and in some
cases unstable. Therefore, it is difficult and
dangerous to pull away in the water.
R Ensure that a bow wave does not form as
you drive.
R Clean any mud from the tire tread after
fording.
R Apply the brakes to dry them after fording.
Winter driving
Important safety notes
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center, at the onset of
winter.
Observe the notes in the "Winter operation"
section ( Y page 173).
i Vehicles with a diesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the
Onboard Diagnosis System may otherwise
provide inaccurate values. Some of these
values are required by law and must
therefore always be accurate.
Winter tires
Use winter tires at temperatures below
45 ‡ (7 †) and on snow or ice-covered roads.
Only winter tires also bearing the i

GWarning!
Please be aware that by raising the vehicle
level, the center of gravity also rises.
Therefore, always ensure that the vehicle
level is as low as possible. With higher ride
height the ESP ®
may activate earlier in certain
situations.
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
General information
Read this section before driving your vehicle
off-road. Practice by traveling over more
gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear change process
before driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
R off-road drive program (vehicles without
the Off-Road Pro engineering package)
( Y page 204)
R LOW RANGE off-road gear ( Y page 157)
R off-road ABS ( Y page 66)
R off-road 4ETS ( Y page 67)
R off-road ESP ®
(Y page 68)
R hill start assist
R differential locks ( Y page 207)
R DSR (Downhill Speed Regulation)
( Y page 203)
Observe the following notes:
R stop your vehicle and, if necessary, select
the off-road drive program (Y page 204) or
the LOW RANGE off-road gear
( Y page 157) before driving off-road.
R select a vehicle level that is suitable for the
terrain. Make sure there is always sufficient
ground clearance to prevent damage to the
vehicle.
R activate the differential lock if necessary.
R make sure that items of luggage and cargo
are stowed safely and are well secured
( Y page 268).
R always keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR ( Y page 203).
R always keep the doors, tailgate, windows
and the tilt/sliding sunroof closed while the
vehicle is in motion.
R adapt the speed to suit the terrain
conditions. The more uneven, worn or
steeper the terrain is, the slower you should
drive.
R drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R look out for obstacles, such as rocks, holes,
tree stumps and furrows.
R check the depth of water before fording
rivers and streams.
R do not stop in water and do not switch the
engine off.
R drive quickly on sand to overcome the
rolling resistance. Otherwise, the vehicle
could dig itself into the sand.
R do not jump with the vehicle. This
interrupts the vehicle's traction.
R always keep the engine running and in gear
when driving on slopes.
R do not shift the automatic transmission to
transmission position N.174Driving tipsDriving and parking

LOW RANGE
General notes
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
characteristics of the automatic transmission
are adapted for this purpose. ABS, ESP ®
and
4ETS programs especially adapted to off-road
driving are also activated.
For information on "Off-road driving", see
( Y page 173) . You will find information about
driving safety systems in conjunction with
LOW RANGE in the "Safety" section
( Y page 65).
Shift rangesHIGH RANGERoad position for all
normal driving situationsLOW RANGEOff-road position for
driving off-road and
fording
The gear ratio between the
engine and wheels is only
approximately one third of
that in the HIGH RANGE
road position. The drive
torque is correspondingly
higher as a result.
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
vehicleGWarning!
Always wait until the procedure of shifting
from HIGH RANGE to LOW RANGE – and from
LOW RANGE to HIGH RANGE – has been
entirely completed. During this procedure do
not turn off the engine or shift the automatic
transmission into another gear.
If you do not wait until the shifting procedure
has been entirely completed then it might not
be correctly performed. The transfer case
might be in neutral, thus interrupting the
transfer of power between the engine and the
drive axle.
The vehicle is then freely movable, even if a
gear has been selected, and could
unintentionally be set into motion –
particularly on up – or downhill grades. This
could lead to an accident and cause injury to
yourself and others.
Please observe related messages appearing
in the multifunction display.

Automatic mode
Use automatic mode ; for all driving
situations, including driving off-road or when
fording.
In automatic mode, the differential locks are
engaged and disengaged according to driving
requirements. This guarantees sufficient
traction for most driving situations with
unrestricted vehicle steerability.
XStart the engine.
The differential locks are in automatic
mode. The indicator lamp in selector
wheel : lights up above symbol for
automatic mode ;.
Engaging manually
GWarning!
Never drive on a paved surface with the center
and rear axle differential locks manually
engaged. Ability to steer the vehicle is greatly
reduced when the differential locks are
manually engaged, increasing the risk of an
accident.
For safety reasons, the locks are
automatically released at a vehicle speed
above 31 mph (50 km/h). Nevertheless, you
should only manually lock the differential if
absolutely necessary because engaged locks
will restrict the vehicle drivetrain while
cornering and cause the vehicle to chatter.
This could cause you to lose control of the
vehicle and cause an accident.
! The differential locks must not be
activated when the vehicle is being towed
or while the wheels are spinning.
Only engage the differential locks manually if
traction in automatic mode is insufficient.
At speeds of up to 19 mph (30 km/h), you
can engage the differential locks manually.XStart the engine.XTurn selector wheel : to desired position
= or ?.
The indicator lamp in selector wheel :
lights up at the corresponding symbol.
The engaged differential appears in the
multifunction display:
AThe differential lock for the transfer case
is locked.
If you have not previously selected the off-
road menu ( Y page 220) in the on-board
computer, the message disappears after
about five seconds.
The differential locks are not controlled
automatically. The steerability of the vehicle
is restricted considerably. Drive carefully and
accelerate gently for optimum traction.
! If the differential locks are activated
manually, the wheels scuff on the road
when cornering since the rotation
difference between the wheels is no longer
balanced out.
You can switch back to automatic mode at
any time. For safety reasons, the differential
locks disengage automatically at speeds
above 31 mph (50 km/h). If you stop the
vehicle and switch off the ignition for longer
than ten seconds, the differential locks
switch back to automatic mode.
