If the ESP warning lampv comes on continuously
and warning messages appears in the multifunction
display with the engine running, a malfunction has
been detected in either system. Only partial engine
output will be available.
If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS, ESP and 4-ETS.
If the ESP warning lampv and the
Émalfunction indicator lamp come on and warning
messages appears in the multifunction display, have the
BAS or ESP checked at your authorized Mercedes-Benz
Light Truck Center as soon as possible.
With the ABS malfunctioning, the BAS, ESP and 4-ETS
are also switched off.
For warn in g m ess ages and malfun ction in d icator lamps ,
see page 264 and page 272.
Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lampv in
speedometer dial comes on). For this reason, all wheels,
including the spare wheel, must have the same tire
outside diameter.When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.
In winter operation, the maximum effectiveness of the
ESP is on ly achieved wit h Me rced es -B enz re comm end ed
M+S rated radial-ply tires and / or snow chains.
Synchronizing ESP
If the power supply was interrupted (battery
disconnected or empty), the ESP warning lampv
and warning messages appears in the multifunction
display with the engine running.
Turn steering wheel completely to the left and then to
the right. The ESP warning lampv and the warning
messages in the multifunction display should go out.

If the ESP is switched off, it will be automatically
activated when exceeding a vehicle speed of 37 mph
(60 km / h) or exceeding a severity threshold of side
acceleration.
If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction. The traction control is available between
vehicle speed 0 mph (km / h) and 37 mph (60 km / h).Note:
Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.
The ESP warning lamp, located in the speedometer dial,
starts to flash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.
To return to the enhanced vehicle stability offered by
ESP: press lower half of the switch (the ESP warning
lamp in the speedometer dial goes out).
Important!
If the ESP warning lamp flashes:
•during take-off, apply as little throttle as possible,
•while driving, ease up on the accelerator.

Methods to disengage differential locks
There are two different methods to disengage
differential locks:
•Disengage differential locks in reverse order. When
the rear axle differential lock is disengaged, the
front axle differential lock is automatically
disengaged with it.
Briefly press the previously activated switches for
the differential lock. The correspondending
engagement indicator lamp (4) goes out.
•If the transfer case differential lock is disengaged,
all other differential locks are automatically
disengaged.
Briefly press the switch (1) for the transfer case
differential lock. The engagement indicator
lamps (4) go out.
The function indicator lamp (5) goes out when the
disengagement procedure has been completed.Only when all function indicator lamps (5) have gone
out, the ABS malfunction indicator lamp and the ESP
warning lamp in the instrument cluster go out and the
messages “ESP NOT ACTIVE – LOCK ACTIVE”, “BAS
NOT AVAILABLE – LOCK ACTIVE” and “ABS NOT
ACTIVE – LOCK ACTIVE” in the multifunction display
disappear.
Now the message “ESP – NOT AVAILABLE” appears in
the multifunction display and the ESP warning lamp
comes on. That means the ESP, BAS and ABS functions
are not active yet.
To activate the systems again drive for 3 seconds with a
constant drive behavior.
Note:
If the function lamps do not go out when the differential
locks are disengaged, make minor changes to the
vehicles direction.
