The ESP enhances directional control and reduces
driving wheel spin of the vehicle under various driving
conditions.
Over-/understeering of the vehicle is counteracted by
applying brakes to the appropriate wheel to create a
countervailing vehicle movement. Engine torque is also
limited. The ESP warning lamp, located in the
speedometer dial, starts to flash when ESP is in
operation.Important!
If the ESP warning lampv flashes:
•During take-off apply as little throttle as possible.
•While driving ease up on the accelerator.
•Adapt your speed and driving to the prevailing road
conditions.
•Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see
towing the vehicle on page 324), the engine must be
shut off (electronic key in starter switch position 0 or 1).
Otherwise, the ESP will immediately be engaged and
will apply the rear wheel brakes.
Notes:
The yellow ESP warning lampv in the speedometer
dial comes on with the electronic key in starter switch
position 2. They should go out with the engine running.
Wa r n i n g !
ESP cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded. The ESP cannot prevent
ac c id ent s, i nc l udi ng t hose resul tin g from exc es si ve
speed in turns, or aquaplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESP equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

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.
