Distronic
currently unavailable
See Operator’s Manual
Distronic* is deactivated because the
functionality is impaired by external in-
terferences, e.g. high-frequency sources
such as too stations, speed measuring
systems etc.

Leave the area of the external interference.

Activate Distronic* again (
page 223) when
the message
DISTRONIC available

pears.
Distronic* is deactivated because the
Distronic* sensor has not sensed any
other vehicles or objects, e.g. road sign
or such, for a long time.

Activate Distronic* again (

ESP
inoperative
See Operator’s Man.
The ESP
® as well as BAS and PRE-SAFE
®
have detected a malfunction and
switched off.
The ABS may not be operational.
The brake system is still functioning nor-
mally but without the ABS, BAS, ESP
®
and PRE-SAFE
® available.

Continue driving with added caution.

Have the system checked at an authorized
Mercedes-Benz Center as soon as possible.
Failure to follow these instructions increases the
risk of an accident.
!
When synchronizing the ESP
®, make sure
you can turn the steering wheel in both direc-
tions as far as it will go without the wheels hitting
any objects, e.g. a road curb.

Possible cause/conse-
quence
Possible solution
(USA only)Front passenger
airbag enabled
See Operator’s Manual
Front passenger front air bag is
activated while driving even
though a child, small individual,
or object below the system’s
weight threshold is on the front
passenger seat, or the front
passenger seat is empty. Ob-
jects on the seat or forces act-
ing on the seat may make the
system sense supplemental
weight.
Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Apply the parking brake.

Switch off the ignition (
page 38).

Open the front passenger door.

Remove child and child restraint from front passenger seat and
properly secure the child in rear seat employing the child restraint
if necessary.

Remove any other items from on and around the front passenger
seat and make sure the storage pocket on the back of the front pas-
senger seat is empty.

Make sure that no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc. lodged behind
or around the seat, head restraints pushing against roof etc.). The
system may recognize such forces as supplemental weight and
sense that an occupant on the front passenger seat is of a greater
weight than actually present.

Keep the seat unoccupied, close the front passenger door and turn
on the ignition (
page 38).

The battery is no longer charging.
Possible causes:

alternator malfunctioning


broken poly-V-belt
Do not forget that the brake system
requires electrical energy and may be
operating with restricted capability.
Considerably greater brake pedal force is
required and the stopping distance is
increased.

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
inoperative 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
authorized Mercedes-Benz Center.
Adjust driving to be consistent with
reduced braking responsiveness.

Battery/Alternator
Stop vehicle
The battery is malfunctioning.
The brake system requires electrical en-
ergy and therefore has only limited oper-
ation. Considerably greater brake pedal
force is required and the stopping dis-
tance is increased.

Stop the vehicle as soon as it is safe
to do so. Adjust driving to be consis-
tent with reduced braking responsive-
ness.

Call Roadside Assistance.

Notify an authorized Mercedes-Benz
Center.

There is insufficient brake fluid in the
reservoir.

Risk of accident! 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!

Driving with the messages
Check brake
fluid level
displayed can result in an ac-
cident. Have your brake system checked im-
mediately.
Do not add brake fluid before checking the
brake system. Overfilling the brake fluid res-
ervoir can result 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.

Coolant
Stop, turn engine off
The coolant is too hot.

Stop the vehicle in a safe location or as soon
as it is safe to do so and immediately turn
off the engine.

Only start the engine again after the mes-
sage disappears. You could otherwise dam-
age the engine.

Apply the parking brake (
page 53).

Observe the coolant temperature indicator
in the instrument cluster (
page 26).
If the temperature rises again:

Contact an authorized Mercedes-Benz
Center immediately.
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.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
until the engine has cooled down.
!
The engine should not be operated with the
coolant temperature above 248°F (120°C).
Doing so may cause serious damage which is not
covered by the Mercedes-Benz Limited
Warranty.
