Cleaning the panorama roof with
tilt/sliding panel*
The rear part of the tilt/sliding panel has a
protective layer on the inside.
Use a soft, clean cloth and a mild win-
dow cleaning solution.
An automotive glass cleaner is recom-
mended.Light alloy wheels
If possible, clean wheels once a week.
Use Mercedes-Benz approved Wheel
Care, a soft bristle brush and a strong
spray of water for cleaning the light al-
loy wheels.Plastic and rubber parts
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Instrument cluster and cup holders
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution.
Wipe with a cloth moistened in a luke-
warm solution.
!
Do not use a dry cloth, abrasives, solvents
or cleaners containing solvents. Do not touch
the protective layer with hard objects such as an
ice scraper or ring. Never apply strong force and
only use a soft, non-scratching cloth when clean-
ing the rear part of the tilt/sliding panel.
Otherwise you may scratch or damage the pro-
tective layer.
!
Only use acid-free cleaning materials. Acid
may cause corrosion or damage the clear coat.
!
The vehicle should not be parked for an ex-
tended period of time immediately after it has
been cleaned, especially not after the wheel rims
have been cleaned with wheel rim cleaner.
Wheel rim cleaners can lead to increased corro-
sion of the brake disks and brake pads. There-
fore, the vehicle’s brake system should always
be warmed-up before it is parked after cleaning.
To do so, please drive your vehicle for several
minutes to allow the brakes to dry.
When applying Mercedes-Benz approved Tire
Care and Mercedes-Benz approved Wheel Care
products, take care not to spray them on the
brake disks.
!
Do not use oil or wax on these parts.
!
To prevent scratches, do not use scouring
agents.

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/consequence
Suggested solution
-
The yellow Antilock Brake
System (ABS) indicator lamp
comes on while the engine is
running.
The ABS has detected a malfunction and
has switched off. The BAS, ESP
® and
PRE-SAFE
® are also switched off (see mes-
sages in multifunction display).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as Parktronic*, DIS-
TRONIC Plus*, navigation system, Park As-
sist* and 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 mul-
tifunction display (
page 557).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions increas-
es the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be charged sufficiently.
When the voltage is above this value again,
the ABS is operational again and the ABS in-
dicator lamp should go out.
If the ABS indicator lamp does not go out:
Have the generator (alternator) and the
battery checked.

554 Practical hintsWhat to do if …?Warning!
G
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or the tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or the tire inflation pressure label,
you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor-
ing system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significant-
ly under-inflated tire causes the tire to over-
heat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Please
note that the TPMS is not a substitute for
proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately
one minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety
of reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your vehicle
to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue
to function properly.
