352 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during the bulb self-check when switching on the igni-
tion, have the respective bulb checked and 
replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction 
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 display).
The SBC brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning, oth-
er systems such as Distronic*, or the auto-
matic 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 
display (
page 362).
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 may not be sufficiently charged.
Switch off electrical consumers that 
are currently not needed, e.g. seat 
heating.
If necessary, have the generator and 
battery checked.
When the voltage is above this value 
again, the ABS is operational again.

The yellow ABS/ESP warning 
lamp comes on while driving.
The ESP is deactivated.
Risk of accident!
Adapt your speed and driving to the prevail-
ing road, weather, and traffic conditions.
Switch the ESP back on (
page 92).
If the ESP cannot be switched back on, 
have the system checked at an autho-
rized Mercedes-Benz Center as soon as 
possible.
v
The yellow ABS/ESP warning 
lamp flashes while driving.
The ABS, ESP or traction control has come 
into operation because of detected traction 
loss in at least one tire. Distronic* is deacti-
vated.
Distronic* is switched off. 
When driving off, apply as little 
throttle as possible.
While driving, ease up on the acceler-
ator.
Adapt your speed and driving to the 
prevailing road and weather condi-
tions.
Do not deactivate the ESP.

453 Technical data
Fuels, coolants, lubricants etc.
Engine oils
Engine oils are specifically tested for their 
suitability in our engines and durability for 
our service intervals. Therefore, only use 
approved engine oils and oil filters re-
quired for vehicles with Maintenance Sys-
tem (U.S. vehicles) or FSS PLUS (Canada 
vehicles). For a listing of approved engine 
oils and oil filters, refer to the Factory Ap-
proved Service Products pamphlet, or con-
tact an authorized Mercedes-Benz Center.
Using engine oils and oil filters of specifica-
tion other than those expressly required 
for the Maintenance System (U.S. vehi-
cles) or FSS PLUS (Canada vehicles), or 
changing of oil and oil filter at change inter-
vals longer than those called for by the 
Maintenance System (U.S. vehicles) or 
FSS PLUS (Canada vehicles) will result in 
engine damage not covered by the 
Mercedes-Benz Limited Warranty.Please follow Maintenance System (U.S. 
vehicles) or FSS PLUS (Canada vehicles) 
recommendations for scheduled oil chang-
es. Failure to do so could result in engine 
damage not covered by the 
Mercedes-Benz Limited Warranty.
Engine oil additives
Do not blend oil additives with engine oil. 
They may damage the engine.Damage or 
malfunctions resulting from blending oil 
additives are not covered by the 
Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG 
lubricating oil are used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the 
system will occur.
Brake fluid
During vehicle operation, the boiling point 
of the brake fluid is continuously reduced 
through the absorption of moisture from 
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture 
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency. Therefore, the brake fluid 
must be replaced every two years, prefera-
bly in the spring.Only brake fluid approved 
by Mercedes-Benz is recommended. Your 
authorized Mercedes-Benz Center will pro-
vide you with additional information.
