ì
Park position
Gear selector lever position
when the vehicle is parked. Place
gear selector lever in positionP
only when vehicle is stopped.
The park position is not intended
to serve as a brake when the
vehicle is parked. Rather, the
driver should always set the
parking brake in addition to
placing the gear selector lever in
positionP to secure the vehicle.
EffectThe SmartKey can only be
removed from the starter switch
with the gear selector lever in
positionP. With the SmartKey
removed, the gear selector lever
is locked in positionP.
If the vehicle’s electrical system
is malfunctioning, the gear
selector lever could remain
locked in positionP
(page 327).

No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).

except:

to coast when vehicle is in
danger of skidding (e.g. on
icy roads) when the ESP is
deactivated or malfunction-
ing

Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, positionP alone is not in-
tended to or capable of preventing your ve-
hicle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 57).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gear selector lever from
positionP, which could result in an accident
and/or serious personal injury.

156 Controls in detailDifferential locksFor more information on off-road driving,
see “Off-road driving” (
page 223).
Differential locks improve the vehicle’s
tractive power off-road. Switch on differen-
tial locks:


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.

Differential locks
A few words about differentials and differential 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, makes this essential function pos-
sible.
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 154) also en-
hances off-road driving capabilities
(
page 223).
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 158). 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 cannot be handled by the
systems (automatic 4-ETS, the ESP, manu-
al switch position “LOW” of transfer case)
this vehicle comes equipped with.

2,3.
!To avoid damage to the transfer case
and differential locks:

Engage differential locks only at low
speed (walking speed, not more
than 5 mph).


Do not engage differential locks if
the driving wheels are spinning due
to lack of traction.


Do not engage on paved roads.

Switching differential locks off
There are two different methods to disen-
gage differential locks:


You can switch the differential locks off
in reverse order (3, 2,1).


To switch off all differential locks at the
same time:
Press switch1.
The yellow engagement indicator
lamps4 go out first. The red func-
tion indicator lamps5 go out
when the switching process has
been carried out in the differential.To activate the ESP, BAS and ABS systems,
drive again for three seconds using a con-
stant driving style.
All messages in the multifunction display
disappear. The ESP warning lampv
and the ABS- warning lamp in the in-
strument cluster go out.
iIf the function lamps do not go out
when the differential locks are disen-
gaged, bring vehicle to a stop and then
continue driving. Changing the vehicle
load can help to disengage locks. Warning!
G
Always remember to disengage the differen-
tial locks when returning to drive on paved
roads, see “A few words about differentials
and differential locks” (
