and rear axle differential to improve vehicle
traction.
The center differential compensates for
differences in wheel rotation between the
front and rear axle.
The rear axle differential compensates
differences between the rear wheels.
i At the front axles, the 4-ETS system
compensates for any traction problems.
For more information on off-road driving, see
“Off-road driving” ( Y page 262).
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 120) 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 two
differential locks: transfer case (center) and
rear. Each can be engaged simply by
operating the rotary switch located on the
center console ( Y page 123). When the
transfer case (center) differential is locked,
the combined (or average) speed of the front
wheels is identical to the combined rear
wheel speed. When the rear differential is
locked, both rear wheels turn at the same
speed, independent of the individual 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
transfer case in LOW RANGE mode) this
vehicle comes equipped with.
Switching differential locks
! If the differential locks are engaged,
accelerate gently when setting the vehicle
in motion.
Only operate the vehicle on a single axle
dynamometer if the axle not being driven is
jacked up or the associated propeller shaft
is disconnected.
Otherwise the transmission could be
damaged.

tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.GWarning!
If ice has formed on the road, tire traction will
be substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.
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 257) 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. The wheels could come
loose if they are not tightened to a torque of
110 lb-ft (150 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 246).
In some cases, such as when your vehicle is
equipped with mixed-size tires (different tire

100% grade which is equivalent to a slope
angle of 45°. Keep in mind that the
climbing ability of the vehicle depends on
terrain conditions.
R Shift automatic transmission into gear
range 1 (Y page 118).
R Drive slowly.
R Avoid excessive engine speeds – drive with
moderate engine speeds (max. 3 000 rpm).
R Utilize the engine’s braking power when
descending a slope, observe the engine
speed (do not overrev the engine). Apply
the service brake as needed.
i For maximum engine speed, see
“Tachometer” (Y page 125) and see vehicle
specification for your vehicle
( Y page 362).
R Check 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.
i The hill-start assist system supports you
when driving uphill.
For more information, see “Hill-start assist
system” ( Y page 155).
Traction in steep terrain
The maximum vehicle climbing ability is a
100% grade which is equivalent to a slope
angle of 45°. Keep in mind that the climbing
ability of the vehicle depends on terrain
conditions.
Be easy on the accelerator and watch for
continuous wheel traction when driving in
steep terrain.
i The 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 towards the rear 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.
i Vehicles with enhanced off-road package
are equipped with automatic locks for the
center and rear axle differential to improve
vehicle traction.
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.
Use the momentum of the vehicle to drive
across the hilltop.
After climbing a hill, driving in this manner
prevents the vehicle from:
R losing ground contact when cresting hills
R losing its forward momentum
R speeding up too much after climbing the hill
Driving downhill
R Drive slowly.
R Do not drive at an angle to the incline. Steer
into the line of gravity and drive with the
front wheels pointing straight downhill.
Otherwise, the vehicle may slide sideways
off the path and roll over.
R Shift automatic transmission into gear
range 1 (Y page 118).
R On steep inclines, use the Downhill Speed
Regulation ( Y page 155).
R Utilize the engine’s braking power to
reduce vehicle speed.
If this is insufficient, apply the brakes
gently. Make sure the vehicle is moving in
the line of gravity.
R Check the brakes after a lengthy
downgrade drive.
