replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while the engine is
running.
The ABS has detected a malfunction and has
switched off. The BAS, ESP
®, EBP and
PRE-SAFE
® are also switched off (see
messages in the multifunction display).
The brake system is still functioning normally
but without the ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as the Parktronic system*,
Distronic*, or 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
multifunction display (
page 396).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery might not be charged sufficiently.
When the voltage is above this value
again, the ABS is operational again and
the ABS indicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and
the battery checked.

The yellow ESP
® warning lamp
comes on while the engine is
running.
The ESP
® has been switched off.
Risk of accident!
When the ESP
® is switched off it will not sta-
bilize the vehicle if the system recognizes
that the vehicle starts to skid or that a wheel
is spinning.

Switch the ESP
® back on (
page 104).
Exceptions: (
page 102).

If leaving the ESP
® switched off, adapt
your speed and driving to the prevailing
road and weather conditions.
If the ESP
® cannot be switched back on:

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
The ESP
® is not operational due to a malfunc-
tion.
Risk of accident!

Observe additional messages in the
multifunction display.

Continue driving with added caution.

Adapt your speed and driving to the
prevailing road and weather condi-
tions.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.

The red brake warning lamp
comes on while driving and
you hear a warning sound.
You are driving with the parking
brake set.

Release the parking brake.

Observe the additional message in
the multifunction display.
The red brake warning lamp
comes on when the engine is
running and you hear a warn-
ing sound.
There is insufficient brake fluid in
the reservoir.

Risk of accident! Do not drive any fur-
ther. Consult a Mercedes-Benz
Service Center. Under no circum-
stances should you top up the 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
system.
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.

The yellow engine mal-
function indicator lamp
comes on while driving.
There may be a malfunction in the

fuel management system


ignition system (gasoline engine)


emission control system


systems which affect emissions
Such malfunctions may result in excessive
emissions values and may switch the engine
to its limp-home (emergency operation)
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
accurate identification of system malfunc-
tions through the readout of diagnostic trou-
ble codes. It is located in the front left area
of the footwell next to the parking brake.

Some states may by law require you to visit
a workshop immediately as soon as the engine
malfunction indicator lamp comes on. Check lo-
cal requirements.

comes on while driving.
A loss of pressure has been detected in the
fuel system. The fuel cap may not be closed
properly or the fuel system may be leaky.

Check the fuel cap.
If it is not closed properly:

Close the fuel cap.
If it is closed properly:

Have the fuel system checked by an autho-
rized Mercedes-Benz Center.
Your fuel 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 red coolant temperature
warning lamp comes on when
the engine is running.
There is insufficient coolant in the reservoir.
If this warning lamp comes on frequently,
there is a leak in the cooling system.
If the coolant level is correct, the electric ra-
diator fan may be broken.

Immediately add coolant to prevent
engine from overheating
(page 330).

Have the cooling system checked.

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.
The red coolant temperature
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 overheated 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 which can occur just by open-
ing the engine hood. Stay away from the en-
gine 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.

The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system re-
quires electrical energy and may be oper-
ating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is in-
creased.

Stop immediately in a safe location or
as soon as it is safe to do so and
check the poly-V-belt.
If it is broken:

Do not continue to drive. Otherwise
the engine will overheat due to an in-
operative water pump which may re-
sult in damage to the engine. Notify
an authorized Mercedes-Benz Center.
If it is intact:

Drive immediately to the nearest au-
thorized Mercedes-Benz Center. Ad-
just driving to be consistent with
reduced braking responsiveness.
There is a malfunction in the electronic
system.

Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
