G WARNING
Braking performance can be impaired.
There is a risk of an accident. X Vehicles with steering wheel buttons: also observe the mes-
sages in the display (Y page 197).
X Stop the vehicle as soon as possible, paying attention to road
and traffic conditions.
X Check the brake fluid level in the expansion tank (Y page 254).
X If the brake fluid is below the MIN mark: do not drive on!
X Do not add brake fluid. This does not solve the problem.
X Consult a qualified specialist workshop. 0065

WARNING
The brake force booster in the trailer is faulty.
The driving and braking characteristics of your vehicle could
change. There is a risk of the trailer overbraking and of you losing control over the truck/trailer combination.
There is a risk of an accident.

0050
0050Solutions 0025
The yellow ABS
indicator lamp is
lit while the
engine is run-
ning. ABS is deactivated due to a malfunction or is temporarily unavail-
able. ESP ®
, ASR and BAS, as well as cruise control, are also
unavailable as a result.
Self-diagnosis may not be complete, or the battery may not be
charging.
G WARNING
The brake system continues to function normally, but without the functions listed above. The wheels could therefore lock, e.g. if thebrakes are applied with maximum force.
This causes steerability and braking to be greatly impaired.
The braking distance can increase in emergency braking situa-
tions.
The driven wheels can spin when accelerating.
If ESP ®
is not operational, ESP ®
will not stabilize the vehicle.
There is an increased risk of skidding and accidents.
X Drive a short distance at a speed above 13 mph (20 km/h).
The functions mentioned above are available again when the
indicator lamp goes out.
If the indicator lamp does not go out: X Drive on with care.
X Visit a qualified specialist workshop immediately. 00E2
The yellow DEF
indicator lamp is
lit while the
engine is run-
ning. The exhaust gas aftertreatment is malfunctioning or the current
Diesel Exhaust Fluid (DEF) supply is limiting the vehicle range.

Cleaning the trailer tow hitch !
Do not clean the ball coupling with a
power washer. Do not use solvents.
! Observe the notes on care in the Opera-
tor's Manual for the trailer tow hitch and
the ball coupling manufacturer.
You can also have the maintenance work on
the ball coupling and the trailer tow hitch car-
ried out by a qualified specialist workshop. Interior
Cleaning with power washers !
When using liquids to clean the vehicle
interior, observe the following points:
R Under no circumstances use power
washers.
R Make sure that no fluids enter or remain
in gaps and cavities.
R Ensure sufficient ventilation when clean-
ing.
R Make sure that the vehicle interior is
completely dry after cleaning.
Cleaning the display !
For cleaning, do not use any of the fol-
lowing:
R alcohol-based thinner or gasoline
R abrasive cleaning agents
R commercially-available household clean-
ing agents
These may damage the display surface. Do not put pressure on the display surface
when cleaning. This could lead to irrepara-
ble damage to the display. X
Switch off the audio equipment and let the
display cool down.
X Clean the display surface with a commer-
cially available microfiber cloth and cleaner
for TFT/LCD displays.
X Dry the display surface using a dry micro-
fiber cloth.
Cleaning the plastic trim G
WARNING
Care products and cleaning agents containing solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag deploy-
ment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You can otherwise damage the plastic.
! Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality look of the surfaces.
X Wipe the plastic trim and the cockpit with a
damp, lint-free cloth, e.g. a microfiber
cloth.
X Heavy soiling: use a mild detergent or care
products and cleaning agents recommen-
ded and approved by Mercedes-Benz.
Cleaning the steering wheel and selec-
tor lever X
Thoroughly wipe with a damp cloth.

CareMaintenance and care

Information about oil consumption
!
If the vehicle is predominantly used for
short-distance driving, this could lead to a
malfunction in the automatic cleaning func- tion for the diesel particle filter. As a result,
fuel may accumulate in the engine oil and
cause engine failure.
Therefore, if you mainly drive short distan-
ces, you should drive on a highway or on
rural roads for 20 minutes every 310 miles
(500 km). This ensures sufficient regener-
ation of the diesel particle filter.
Depending on the driving style, the vehicle
consumes a maximum of 1.0 US qt (1.0 l) of
engine oil over a distance of 620 miles
(1000 km).
Oil consumption may be higher if:
R the vehicle is new.
R you mainly operate the vehicle under ardu-
ous operating conditions.
R you frequently drive at high engine speeds.
Regular maintenance is one of the precondi-
tions for moderate rates of consumption.
You can only estimate the oil consumption
after you have driven a considerable distance.
Check the engine oil level on a regular basis,
e.g. weekly or each time you refuel
(Y page 250). Transmission and power steering oil
