-
The yellow ABS indicator
lamp comes on while driving.
The ABS has detected a malfunction and
has switched off. The BAS and the ESP
®
are also switched off (see messages in dis-
play).
The electrohydraulic brake system is still
functioning normally but without ABS
available.
If the ABS control unit is malfunctioning
the automatic transmission may also be
malfunctioning.

Continue driving with added caution. Wheels
may lock during hard braking, reducing
steering capability.

Read and observe messages in the multi-
function display (
page 307).

Have the system checked at an authorized
Mercedes-Benz Center immediately.
Failure to follow these instructions increases
the risk of an accident.
The charging voltage has fallen below
10 volts and the ABS was switched off.
When the voltage is above this value again, the
ABS is operational again.
If necessary, have the generator and battery
checked.

The red brake warning lamp
comes on while driving.

reservoir.

Risk of accident! Carefully stop the vehicle in
a safe location and notify an authorized
Mercedes-Benz Center. Do not add brake
fluid! This will not solve the problem.
Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake sys-
tem.
Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

(Canada only)
The yellow engine malfunc-
tion indicator lamp comes on
while driving.
There is a malfunction in:

The fuel injection system


The ignition system


The emission control system


Systems which effect emissions
Such malfunctions may result in excessive
emissions values and may switch the en-
gine to its limp-home (emergency opera-
tion) mode.

Have the vehicle checked as soon as possi-
ble by an authorized Mercedes-Benz Center.
An on-board diagnostic connector is used by
the service station to link the vehicle to the
shop diagnostics system. It allows the accu-
rate identification of system malfunctions
through the readout of diagnostic trouble
codes. It is located in the front left area of
the footwell next to the parking brake.
Your gas tank is empty.

After refuelling, start, turn off and restart the
engine three or four times in succession.
The limp-home mode is canceled. You do not
need to have your vehicle checked.
The fuel cap is not closed tightly.

Check the fuel cap.

D
The red coolant warning lamp
comes on when the engine is
running.
There is insufficient coolant in the reservoir.

Immediately add coolant to prevent
engine from overheating
(page 250).
If this warning lamp comes on frequently,
there is a leak in the cooling system.

Have the cooling system checked by
an authorized Mercedes-Benz Center.
If the coolant level is correct, the electric
radiator fan may be broken.

If the coolant temperature is below
248°F (120°C), you can continue
driving to the nearest authorized
Mercedes-Benz Center.

Avoid high engine loads (e.g. driving
uphill) and stop-and-go driving.
D
The red coolant warning lamp
comes on while driving and you
hear a warning sound.
The coolant temperature has exceeded
248°F (120°C).

Stop as soon as possible in a safe lo-
cation and allow the engine and cool-
ant to cool down.
Warning!
G
Driving when your engine is badly overheat-
ed can cause some fluids which may have
leaked into the engine compartment to
catch fire. You could be seriously burned.
Steam from an overheated engine can cause
serious burns and can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
