Electronic Stability Program
(ESP)
The ESP enhances directional control
and improves traction of the vehicle
under any driving condition.
Over/understeering of the vehicle is
counteracted by applying brakes to the
left or right side wheels. The ESP
warning lamp, located in the
speedometer dial, starts to flash.
Important!
If the ESP warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.
Caution!
If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), the engine must be shut off.
Otherwise, the electronic stability
program will immediately be engaged
and will apply the rear wheel brakes.
Notes:
With the key in steering lock position
2, the yellow ESP and EPC
malfunction indicator lamps in the
instrument cluster and the yellow
warning lamp in the speedometer dial
come on. They must go out when the
engine is running.
If the ESP or EPC malfunction
indicator lamp comes on with the
engine running, a malfunction has been
detected. It is possible that now only
partial engine output is available.
Have the ESP checked at your
authorized Mercedes-Benz dealer as
soon as possible.
With the ABS malfunctioning, the ESP
is also switched off.
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
electronic stability program may
activate (yellow ESP malfunction
indicator lamp in instrument cluster
comes on). For this reason, all wheels,
including the spare wheel, must have
the same tire size.
When testing the parking brake on a
brake test dynamometer, the engine
must be shut off. Otherwise, the
electronic stability program will
immediately be engaged and will apply
the rear wheel brakes.
In winter operation, the maximum
effectiveness of the electronic stability
program is only achieved with
Mercedes-Benz recommended M + S
radial-ply tires and/or snow chains.
