To engage: switch the transfer case to the
LOW RANGE off-road driving position
( Y page 132).
X Press switch =.
If the transfer case is in the LOW RANGE
off-road position, the yellow activation indi- cator lamp under switch =lights up.
The å warning lamp in the instrument
cluster lights up.
If the differential is locked, the red function indicator lamp above switch =lights up.
In the multifunction display you see the:
ABS not available differential
lockedmessage.
The å!÷ warning lamps light up
in the instrument cluster.
The differential lock for the transfer case is
engaged.
4ETS, ESP ®
, BAS and ABS are deactivated.
The vehicle's ability to steer is severely
restricted. Drive carefully and accelerate gen-
tly for optimum traction.
iYou can now engage the differential lock
for rear axle ?and the differential lock for
front axle ;as required.

X To engage: press switch ;.
First, the yellow activation indicator lamp
lights up, followed by the red function indi- cator lamp.
The differential lock for the front axle is
engaged.
Disengaging the differential locks
You can disengage the differential locks in the
following order: ;,? ,= .
X To simultaneously disengage all differ-
ential locks: press switch=.
Yellow activation indicator lamps Aand
red function indicator lamps :go out.
After approximately three seconds of nor-
mal driving, ABS, 4ETS, ESP ®
and BAS are
activated.
The
ABSnotavailabledifferential

function display and the å,! and
÷ warning lamps in the instrument clus-
ter go out.
X Shift the transfer case to the HIGH RANGE
on-road position ( Ypage 132).
iIf red function indicator lamps :do not
go out when disengaging the differential
locks, stop the vehicle safely as soon as
possible, in accordance with the traffic con- ditions. Then, continue driving and the load
change can release the differential lock.

stopping and backing up in a traffic-free location.
R Before driving, check:
- Trailer tow hitch
- Safety switch for braked trailers
- Safety chains
- Electrical connections
- Lights
- Wheels
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer features electronically control-
led brakes, pull away the vehicle/trailer
combination carefully, manually brake
using the brake controller, and check the
brakes for correct function.
R Secure any objects on the trailer to prevent
the cargo from slipping when the vehicle is
in motion.
R If you couple up a trailer, regularly check
the cargo for secure fastening and make
sure that the trailer lamps and (if applica-
ble) the trailer brakes are functioning cor-rectly.
R Bear in mind that the handling will be less
stable when towing a trailer than when driv-
ing without one. Avoid sudden steeringmovements.
R The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient climbing capability and a longer
braking distance.
It is more susceptible to side winds and
requires more careful steering.
R If possible, avoid abrupt braking. Depress
the brake pedal moderately at first, so that
the trailer can activate its own brakes. Thenincrease the pressure on the brake pedal.
R If the automatic transmission continues to
shift back and forth between two gears
when driving up or downhill, restrict the
shift range. Select shift range 4, 3, 2,or1.
A lower gear and lower speed reduce the
risk of engine failure. R
When driving downhill, shift to a lower gear
to utilize the engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can additionally be dissipated
by opening the windows and by setting the
blower fan and the interior temperature tomaximum.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination, you will have to travel an addi-
tional distance beyond the vehicle you are
overtaking before returning to the previous lane.
Decoupling a trailer
!
Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
X Make sure that the automatic transmission
is set to position P.
X Apply the parking brake.
X Start the engine.
X Close all doors, including the rear door.
X Apply the trailer's parking brake.
X Detach the trailer cable and decouple thetrailer.
X Switch off the engine.

Useful information
iThis Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops: ( Ypage 28).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose controlof the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-ately.
The on-board computer only shows messages
or warnings from certain systems in the mul- tifunction display. You should therefore make
sure your vehicle is operating safely at all
times. Otherwise, a vehicle that is not oper-
ating safely may cause an accident. You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
For an illustration of the instrument cluster,
see ( Ypage 146).
