203 Operation
Driving instructions
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 select gear rangeN), to prevent the
vehicle from speeding up too much af-
ter climbing a hill.
Use the momentum of the vehicle to
drive across the hilltop.
Driving in this manner prevents the ve-
hicle from jumping across the hilltop
and thus loosing its forward momen-
tum.Driving downhill


Select gear range1 on the automatic
transmission (
page 121).


Drive downhill observing the same
rules as driving uphill (
page 202).


The special LOW RANGE – ABS setting
allows for precise and brief (cyclical)
blocking of the front wheels, permitting
them to dig into loose ground.
Remember that the front wheels when
stopped, slide across a surface, thus
loose their ability to steer the vehicle.Driving through water
120 in (50 cm)


Before driving through water, deter-
mine its depth.
It should not be deeper than approxi-
mately 20 inches (50 cm).
Make sure you check the water bed.
The ground surface may not be firm
which may result in deeper waters than
expected when driving the vehicle
through it.


Switch to LOW RANGE mode before
driving through water (
page 125).

229 Operation
Tires and wheels
Warning!
G
Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
110 lb-ft (150 Nm).
Use only genuine Mercedes-Benz wheel
bolts specified for your vehicle's rims.

277 Practical hints
Flat tire
1-5Wheel bolts
Tighten the five wheel bolts evenly, fol-
lowing the diagonal sequence illustrat-
ed (1 to 5), until all bolts are tight.
Observe a tightening torque of
110 lb-ft (150 Nm).

Store jack and tool kit.Warning!
G
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).iThe removed road wheel cannot be
stored in the spare wheel carrier, but
should be transported in the rear cargo
compartment wrapped in a protective
cover supplied with the vehicle.
The protective cover is located in the
rear cargo compartment behind the
cover in the right side trim panel.
