Brake warning lamp
Except Canada
Canada only
When the brake warning lamp and message appear
while the engine is running, this means:
•there is insufficient brake fluid in the reservoir
(engine running and parking brake released), or
•the parking brake is set (engine running).Note:
If you find that the minimum mark on the brake fluid
reservoir is reached, have the brake system checked for
brake pad thickness and leaks.
Wa r n i n g !
Driving with the brake warning lamp illuminated
can result in an accident. Have your brake system
checked immediately if the brake warning lamp
stays on. Don’t add brake fluid before checking the
brake system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You can be
seriously burned.

ABS malfunction indicator lamp
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 remains illuminated while the
en gin e is r unn in g, it in d icates that t he AB S has d etec te d
a malfunction and has switched off. In this case, the
brake system functions in the usual manner, but
without antilock assistance.
A malfunctioning ABS control unit can possibly affect
the operation of other systems (e.g. Parktronic,
Navigation, Automatic transmission). Be guided
accordingly with respect to the use of those systems and
have the system checked at your authorized
Mercedes-Benz Center as soon as possible.With the ABS malfunctioning, the BAS and ESP are also
switched off. The malfunction indicator lamp and
malfunction messages in the multifunction display
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 of f. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 276 for notes on antilock brake system (ABS).

1 One or more tires is or has deflated rapidly. Carefully bring the
vehicle to a halt, avoiding abrupt steering and braking maneuvers.
For reference on changing wheels, see page 343.
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 153.4 Tire pressure in one or more tires is low. Check and correct tire
pressure according to the label affixed inside the fuel filler flap.
For tire inflation pressure, see page 351.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 153.
5 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 351.
The tire inf lation pressure monitor must be activated again after
the tire inflation pressure has been corrected, see page 153.
6 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.
7 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.
