Mercedes-Benz E 320 Wagon 1999 ASR - Manual (Page 5)

105
Electronic Stability Program
(ESP) (optional)
The ESP enhances directional control
and reduces driving wheel spin of the
vehicle under any driving condition.
Over/understeering of the vehicle is
counteracted by applying brakes to the
appropriate wheel to create a
counterpointing vehicle movement.
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
(electronic key in steering lock position
0 or 1). Otherwise, the ESP will
immediately be engaged and will apply
the rear wheel brakes.
Notes:
The malfunction indicator lamp for the
ESP is combined with that of the BAS.
The yellow BAS/ESP malfunction
indicator lamp in the instrument cluster
and the yellow ESP warning lamp in
the speedometer dial come on with the
electronic key in steering lock position
2. They should go out with the engine
running.
If the BAS/ESP malfunction indicator
lamp comes on permanently with the
engine running, a malfunction has been
detected in either system. Pressing the
accelerator pedal will require greater
effort. Only partial engine output will
be available.
If the BAS malfunctions, the brake
system functions in the usual manner,
but without BAS.
Have the BAS or 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 ESP may
activate (yellow ESP warning lamp in
speedometer dial 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 ESP
will immediately be engaged and will
apply the rear wheel brakes.
In winter operation, the maximum
effectiveness of the ESP is only
achieved with Mercedes-Benz
recommended M+S rated radial-ply
tires and/or snow chains.
Synchronizing ESP
If the power supply was interrupted
(battery disconnected or empty), the
BAS/ESP malfunction indicator lamp
may be illuminated with the engine
running.
Turn steering wheel completely to the
left and then to the right. The BAS/ESP
malfunction indicator lamp should go
out.
