Shifting to neutral G
WARNING
When the transfer case is in the neutral posi-
tion, power transmission to the driven wheels
is interrupted. As a result, the vehicle could
roll away. There is a risk of an accident.
Secure the vehicle with the parking brake, and on uphill or downhill gradients, also secure it
with a device such as a wheel chock.
X Turn the SmartKey to position 2in the igni-
tion lock (Y page 133).
X Apply the parking brake.
X Depress the brake pedal. X
Move the selector lever to position N
(Y page 139).
X Press and hold LOW RANGE button ;for
approximately 10 seconds.

General notes G
WARNING
When the differential locks are engaged, ABS, 4ETS, ESP ®
and BAS are deactivated. As a
result, the wheels could lock when braking
and the braking distance is increased. There is
a risk of an accident.
Disengage the differential locks immediately
on firm surfaces with good grip.
! In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) only
if:
R the axle not driven on is jacked up
or
R the corresponding propeller shaft is dis-
connected and the transfer case differ-
ential lock is engaged.
Otherwise, the transfer case can be dam-
aged.
Differential locks improve the traction of the
vehicle. 188

Notes on towing a trailer
Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary. G
WARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-tion is longer or angled differently. This could seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow hitch. G
WARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating instructions for the trailer coupling if a
detachable trailer coupling is used.
You will find the applicable permissible val-
ues, which must not be exceeded, in the vehi-
cle documents.
You will find the values approved by the man- ufacturer on the vehicle identification plates
and those for the towing vehicle in the "Tech-
nical data" section (Y page 346).
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load Towing a trailer

i This 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

WARNING
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 control of 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. G
WARNING
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.

WARNING
Driving when your engine is overheated can
cause some fluids which may have leaked into the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.
! A display message is shown if the coolant
temperature is too high. Displays and ope
ration

If the coolant temperature is over 248 ‡
(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gage is in the instru- ment cluster on the right-hand side
(Y page 197).
Under normal operating conditions and with
the specified coolant level, the coolant tem-
perature may rise to 248 ‡ (120 †). Tachometer
! Do not drive in the overrevving range, as
this could damage the engine.
The red band in the tachometer indicates the engine's overrevving range.
The fuel supply is interrupted to protect the
engine when the red band is reached. Outside temperature display
You should pay special attention to road con-
ditions when temperatures are around freez-
ing point.
Bear in mind that the outside temperature
display indicates the temperature measured
and does not record the road temperature.
The outside temperature display is in the mul- tifunction display (Y page 199).
Changes in the outside temperature are dis-
played after a short delay. Speedometer with segments
The segments in the speedometer indicate
which speed range is available.
