Differential locks
General notes G
WARNING
When differential locks are engaged on a firm,
high-grip surface, the vehicle's steerability is
greatly impaired. In particular, engaging the
differential locks when cornering could lead
to you losing control
of the vehicle. There is a
risk of an accident.
Disengage the differential locks immediately
on firm, high-grip surfaces. G
WARNING
ABS, 4ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged. 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, high-grip surfaces.
! 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
disconnected and the transfer case
differential lock is activated.
Otherwise, the transfer case can be
damaged.
Differential locks improve the traction of the
vehicle. Your vehicle is equipped with a differential
lock for:
R
the transfer case: this

controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
between the wheels on the front axle.
Information on differential and
differential locks When the vehicle drives around a curve, the
wheels on the
outside

of the curve must cover
a greater distance. Therefore, the wheels turn
more rapidly than on the inside. The
differential, a transmission in the drive train,
compensates for these different rotational
speeds, making cornering possible.
The disadvantage of a differential is that more
power is transferred to the wheels that have
the least grip. An example: a wheel of a driven
axle is on a snow-covered surface and
therefore does not have any traction. The
differential causes this wheel to be subjected
to the strongest driving force, as the flow of
force takes the path of least resistance. The
opposite wheel on this axle, however, which
stands on firm ground and could therefore
allow propulsion, receives no driving power.
4ETS compensates for this disadvantage.
4ETS provides good steerability by
automatically braking the spinning wheel.
4ETS provides the wheel on the firm surface
with more drive force, which in turn provides
propulsion.
ESP® and 4ETS are traction systems that are
ideal for road driving and suitable for light off-
road driving. The LOW RANGE off-road gear
also improves off-road capability.
Moreover, the more difficult conditions in off-
road driving require further measures such as
locking one or several differentials. Your
vehicle is equipped with three differential
locks: Off-road driving systems

Differential lock for the transfer case
X
To engage: switch the transfer case to the
LOW RANGE off-road driving position ( Y
page 199).
X Press switch 0087.
When the transfer case is in the LOW
RANGE off-road driving position,

the yellow
activation indicator lamp below switch 0087
lights up.
The 00BB warning lamp in the instrument
panel lights up.
When the differential is locked, the red
function indicator lamp above switch 0087
lights up.
In the multifunction display you see the:
ABS not available Differential
Locked
The 00BB002500E5 warning lamps in the
instrument cluster light up.
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
gently for optimum traction.
i You can now engage the differential lock
for rear axle 0085

and the differential lock for
front axle 0044 as required.
Differential lock for the rear axle X
To engage: press switch 0085.
Yellow activation indicator lamp 0083 lights
up first, followed by red function indicator
lamp 0043 of switch 0085.
The differential lock for the rear axle is
engaged.
Differential lock for the front axle X
To engage: press switch 0044.
First, the yellow activation indicator lamp
lights up, followed by the red function
indicator lamp. The differential lock for the front axle is
engaged.
Deactivating the differential lock You can deactivate the differential locks in
this order: 0044, 0085, 0087.
X
To simultaneously deactivate all
differential locks: press switch 0087.
Yellow activation indicator lamps 0083 and
red function indicator lamps 0043 go out.
After approximately three seconds of
normal driving, ABS, 4ETS, ESP ®
and BAS
are activated.
The ABS not available
Differential
Locked

message disappears from the
multifunction display and the 00BB, 0025
and 00E5 warning lamps in the instrument
cluster go out.
X Shift the transfer case to the HIGH
RANGE on-road position (Y page 199).
i If red function indicator lamps 0043 do not
go out after disengaging the differential
locks, bring the vehicle to a standstill in
accordance with the traffic conditions.
Then continue driving, as the load change
can release the differential locks. 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. Towing a trailer

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment 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.

G
WARNING
The driver's concentration must always be
directed primarily at road traffic.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and

road conditions permit
it to be done safely.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired. If you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible.
G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on the vehicle.

Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages. G
WARNING
All categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.
Failure to repair the condition noted may
cause damage not covered

by the Mercedes-

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 Displays and operation

the engine has cooled down.
! A display message is
shown if the coolant
temperature is too high.
If the coolant temperature is over
248 ‡(120 †), do not continue driving. The
engine will otherwise be damaged.
The coolant temperature gauge is in the
instrument cluster on the right-hand side
(Y page 209).
Under normal operating conditions and with
the specified coolant level, the coolant
temperature 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

WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
