The ABS malfunction indicator lamp- in the
instrument cluster comes on with the electronic key in
starter switch position 2 and should go out with the
engine running.
When the ABS malfunction indicator lamp in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
For ABS malfunction indicator lamp, see page 300.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.If the ABS malfunction indicator lamp stays illuminated,
have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
Note:
To alert following vehicles to slippery road conditions
you discover, operate your hazard warning flashers as
appropriate.
Wa r n i n g !
ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded. The ABS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a ABS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.

The yellow ESP warning lampv in the speedometer
dial comes on with the electronic key in starter switch
position 2. It should go out with the engine running.
If the ESP warning message is displayed, a malfunction
has been detected in the system. Only partial engine
output will be available.
Have the ESP checked at your authorized
Mercedes-Benz Center as soon as possible.
For ESP warning message, see page 301.
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 ESP warning message may
be displayed with the engine running.
Turn steering wheel completely to the left and then to
the right. The ESP warning message should go out.

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 f lash 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 (2) of the switch (the ESP warning
lamp in the speedometer dial goes out).
Vehicles with Distronic (DTR):
With the ESP switched off, the Distronic cannot be
switched on. See page 259 for activation of Distronic.Important!
If the ESP warning lamp flashes:
•during take-off, apply as little throttle as possible,
•while driving, ease up on the accelerator.
Wa r n i n g !
ESP should not be switched off during normal
driving other than in circumstances described
above. Disabling of the system will reduce vehicle
stability in standard driving maneuvers.

Raised level, option I
This setting should be used when road surface
conditions are rough and must be used when driving
with snow chains mounted.
Important!
Driving with snow chains requires increased space
between tire and wheel housing. Refer to page 249 for
driving with snow chains.
Speed dependent lowering of vehicle chassis
(approximate values):
•at standstill – raised by approximately
3/4 inch
(20 mm)
•between 35 mph (60 km / h) and 120 mph
(190 km / h) – lowered progressively by
approximately one inch (25 mm)Raised level, option II
This setting should be used when road surface
conditions are very rough for increased ground
clearance.
Speed dependent lowering of vehicle chassis
(approximate values):
•at standstill - raised by approximately one and one
eight inch (30 mm)
•between 0 mph (0 km / h) and 35 mph (6o km / h) -
lowered progressively by approximately
3/8 inch
(10 mm)
•between 35 mph (60 km / h) and 120 mph
(190 km / h) – lowered progressively by
approximately one inch (25 mm)

1 One or more tires def late rapidly or tire pressure is already below
minimum value. Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. For reference on changing
wheels, see page 340.
2 The tire pressure on one or more tires is already below minimum
value. Carefully bring the vehicle to a halt, avoiding abrupt
steering and braking maneuvers. For reference on changing
wheels, see page 343.
3 For tire inflation pressure monitor, see page 150.4 Tire pressure in one or more tires is low. Check and correct tire
pressure, see page 348.
5 The tire pressure monitor cannot be activated with the engine
running. Turn off the engine and repeat activation, see page 150.
6 When the message appears after starting the engine, the tire
inflation pressure on all road wheels should be checked and
corrected according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 348.
The tire inflation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 150.
7 The tire inflation pressure monitor system is unable to monitor the
tire pressure due to the presence of several wheel electronics in
the vehicle (e.g. a deflated road wheel in the trunk), or nearby
radio interference source, or excessive wheel sensor temperatures,
or unrecognized wheel sensors mounted.
8 The tire inflation pressure monitor is defective or a wheel without
proper sensor was installed. Visit your authorized Mercedes-Benz
Center.Wa r n i n g !
Do not drive with a flat tire. A flat tire affects the
ability to steer or brake the vehicle. You may lose
control of the vehicle. Continued driving with a flat
tire will cause excessive heat build-up and possibly
a fire.
