Warning!
G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving. For your safety and the
safety of others, we recommend that you
pull over to a safe location and stop before
placing or taking a telephone call. If you
choose to use the telephone while driving,
please use the hands-free device and only
use the telephone when road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or
personal injury.

Differential locks
Differential locks
Information on off-road driving is found in
the “Operation” section (
page 203).
Differential locks improve the vehicle’s
tractive power off-road. Switch differential
locks on:
for off-road driving
to turn the ABS off during off-road driv-
ing
for driving through water
when driving on deep snow and icy or
fouled surfaces!Do not engage the front axle differen-
tial lock when driving around tight cor-
ners. This restricts steering ability.
!When driving off-road, apply only mod-
erate pressure to the accelerator pedal
if the differential locks are switched on.
When running on a (single-axle) dyna-
mometer – no matter how briefly – you
must:
raise the non-driven axle
or
disconnect its drive shaft
and
engage the transfer differential lock
Otherwise the transfer case can be
damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Never drive on pavement with differential
locks engaged.
Steering control will be strongly affected
with the differential locks activated.
The ABS, BAS and ESP are switched off au-
tomatically when the transfer case differen-
tial lock is activated.
144 Controls in detailDifferential locksA few words about differentials and dif-ferential locks
When a vehicle negotiates a turn, wheels
on the outside of the curve must travel far-
ther 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, make this essential function possi-
ble.
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 en-
gine's power will go to that wheel because
the power will take the path of least resis-
tance. Meanwhile, the opposite wheel, sit-
ting on dry pavement where it could get
enough grip to start the vehicle moving,
sits idle because it receives no power.The Electronic Traction System (ETS) ad-
dresses this problem and provides for
good control and steering ability by auto-
matically slowing the slipping wheel and
thus increasing the power to the other
non-slipping drive wheels to get the vehicle
moving. The ESP and ETS in this vehicle
feature such intelligent limited-slip differ-
ential technology, ideally suited for
on-road and light off-road driving. Transfer
case position LOW (
page 141) also en-
hances off-road driving capabilities
(
page 203).
More extreme off-road conditions may call
for another solution, engaging a differen-
tial lock or preventing the differential from
operating altogether. As part of its stan-
dard equipment, this vehicle comes with
three differential locks: front, transfer case
(center) and rear. Each can be engaged
simply by pushing dashboard-mounted
buttons in sequential order (center, rear,
front) (
page 145). When the transfer
case (center) differential is locked, half of
the engine's power is automatically distrib-
uted 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.
When the front differential is locked, all
four wheels now turn with equal power 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 impor-
tant to understand that during
on-road/paved driving, differentials are
absolutely necessary for providing the es-
sential 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 can not be handled by
the systems (automatic 4-ETS, the ESP,
manual switch position “LOW” of transfer
case) this vehicle comes equipped with.

162 Controls in detailDriving systems
Driving systemsThe driving systems of your vehicle are de-
scribed on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed.
Rear Park Assist*, with which you can
assist your parking maneuvers.
The BAS, ABS, ESP, 4-ETS and EBB driving
systems are described in the “Safety and
Security” section (
page 71).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time. You can set any speed
over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever found on the left-hand side of the
steering column (
page 22).
iThe cruise control should not be acti-
vated during-off road driving.
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must always
remain responsible for the vehicle speed
and for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.
The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.
The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.
Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
