The ABS, BAS, and ESP® are switched off
automatically when the transfer case
differential lock is activated.
For more information on off-road driving, see
“Off-road driving” (Y page 184).
A few words about differentials and
differential locks
When a vehicle negotiates a turn, wheels on
the outside of the curve must travel farther
and rotate faster than the inside wheels. The
differential, the operation of a set of gears
that allows the powered wheels in a vehicle
to turn at different speeds, makes this
essential function possible.
The drawback is that the differential also
sends most of the engine’s power to the
wheel with the least load or strain on it. For
example, if one of a vehicle’s powered wheels
sits on a patch of snow and spins because
there is no traction, all of the engine’s power
will go to that wheel because the power will
take the path of least resistance. Meanwhile,
the opposite wheel, sitting on dry pavement
where it could get enough grip to start the
vehicle moving, sits idle because it receives
no power.
The 4-ETS addresses this problem and
provides for good control and steering ability
by automatically slowing the slipping wheel
and thus increasing the power to the other
non-slipping drive wheels to get the vehicle
moving. The ESP® and the 4-ETS in this
vehicle feature such intelligent limited-slip
differential technology, ideally suited for on-
road and light off-road driving. Transfer case
position LOW (Y page 93) also enhances off-
road driving capabilities.
More extreme off-road conditions may call for
another solution, engaging a differential lock
or preventing the differential from operating
altogether. This vehicle comes with three
differential locks: front, transfer case
(center), and rear. Each can be engaged
simply by pushing dashboard-mounted
switches in sequential order (center, rear,
front) (Y page 96). When the transfer case
(center) differential is locked, half of the
engine’s power is automatically distributed to
the front wheels and half to the rear wheels.
When the rear differential is locked, power
going to the rear wheels is equally distributed,
so that both rear wheels turn at the same
speed and torque. Please be aware that
engaging the differential locks will
significantly reduce the steering ability of the
vehicle.
For your safety and the safety of others and
to prevent damage to the vehicle, the
differential locks must not be engaged when
driving on paved roads. It is important to
understand that during on-road/paved
driving, differentials are absolutely necessary
for providing the essential control and
steering ability of the vehicle. The differential
locks, therefore, must not be engaged when
driving on paved roads and should only be
used to the extent necessary to negotiate off-
road conditions which cannot be handled by
the systems (the 4-ETS, the ESP®, and the
manual switch position “LOW” of transfer
case) this vehicle comes equipped with.
Switching differential locks on and off
The switches are located on the upper part of
the center console.

The safe speed on a wet, snow covered or icy
road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperature is close to the freezing point.
Mercedes-Benz recommends winter tires
( Y page 179) with a minimum tread depth of
approximately 1
/ 6 in (4 mm) on all four wheels
for the winter season to ensure normal
balanced handling characteristics. On
packed snow, they can reduce your stopping
distance compared to summer tires.
Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise
appropriate caution.
! Avoid spinning of a drive wheel. This may
cause serious damage to the drivetrain
which is not covered by the Mercedes-Benz
Limited Warranty.
Temperature GWarning!
The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.
The temperature grades are A (the highest),
B, and C, representing the tire’s resistance to
the generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Rotating tires
GWarning!
Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs. rear),
tire rotation is not possible.
GWarning!
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel bolts
specified for your vehicle’s rims.
Tire rotation can be performed on vehicles
with tires of the same dimension all around.
If your vehicle is equipped with tires of the
same dimension all around, tires can be
rotated, observing a front-to-rear rotation
pattern that will maintain the intended
rotation (spinning) direction of the tire
( Y page 169).
In some cases, such as when your vehicle is
equipped with mixed-size tires (different tire
dimension front vs. rear), tire rotation is not
possible.
If applicable to your vehicle’s tire
configuration, tires can be rotated according
to the tire manufacturer’s recommended
intervals in the tire manufacturer’s warranty
pamphlet located in your vehicle literature
portfolio. If none is available, tires should be
rotated every 3 000 to 6 000 miles (5 000 to
10 000 km), or sooner if necessary, according
to the degree of tire wear. The same rotation
(spinning) direction must be maintained.
Rotate tires before the characteristic tire
wear pattern becomes visible (shoulder wear
on front tires and tread center wear on rear
tires).

pressures is located on the driver’s door B-
pillar (Y page 166).
RCheck tires for possible damage and
remove foreign objects.
RReplace missing valve caps.
Rims
RDented or bent rims can cause tire inflation
pressure loss and damage the tire beads.
For this reason, check and, if necessary,
change rims before driving off-road.
Vehicle tool kit
RCheck if the jack (Y page 201) is
functional.
RAlways take the vehicle tool kit, a strong
tow rope, a shovel and a small plank (to put
under the jack on sandy soil) with you.
Driving in steep terrain
Slope angle
:Overhang angle, front;Overhang angle, rear:;G 55037°31°G 55 AMG23°26°
RComply with the warnings (Y page 184) and
rules for off-road driving (Y page 185).
RDriving on embankments, slopes and other
steep inclines should only be done straight
up or downhill, i.e. in the line of gravity.
Maximum vehicle climbing ability is a
80% grade which is equivalent to a slope
angle of approximately 38°. Keep in mind
that the climbing ability of the vehicle
depends on terrain conditions.
RShift automatic transmission into gear
range 2 or 1 (Y page 92).
RDrive slowly.
RUtilize the engine’s braking power when
descending a slope, observe the engine
speed (do not overrev the engine). Apply
the service brake as needed.
iFor maximum engine speed, see
“Tachometer” (Y page 99) and see vehicle
specification for your vehicle
(Y page 256).
RCheck the brakes after a lengthy
downgrade drive.
GWarning!
Never turn the vehicle around on steep
inclines. The vehicle might roll over. If the
vehicle cannot complete the attempted climb,
back it down in reverse gear.
Traction in steep terrain
Be easy on the accelerator and watch for
continuous wheel traction when driving in
steep terrain.
iThe 4-ETS helps greatly when starting out
on a steep incline when the front wheels
have then the tendency to slip due to the
weight shifting away from the front axle.
The 4-ETS recognizes the situation and
limits the torque for the front wheels by
braking them.
Simultaneously the torque for the rear
wheels is increased.
Driving across a hilltop
Decelerate just ahead of a hilltop (do not shift
automatic transmission into neutral position
N), to prevent the vehicle from speeding up
too much after climbing a hill.
