266 Controls in detailUseful features
System self-check
Initially, after switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message
Malfunction. Drive to work-
shop
appears in the multifunction display.
iThe SOS button is located in the over-
head control panel.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
iWhen a Tele Aid call has been initiated,
the audio system or COMAND* System
unit is muted and the selected mode
(radio, tape or CD) pauses. The optional
cellular phone (if installed) and inserted
in cradle switches off. If you must use
this phone, we recommend that you
use it only with the vehicle at a stand-
still in a safe location. Remove the
phone from the cradle and place the
call. The navigation* system (if en-
gaged) will continue to run. The multi-
function display in the instrument
cluster is available for use, and spoken
commands are only available by press-
ing the RPT button on audio system or
COMAND* System unit. A pop-up win-
dow will appear in the audio system or
COMAND* System unit display to indi-
cate that a Tele Aid call is in progress.
After the TeleAid call has ended, the
optional cellular phone switches on
again. A PIN entry might be necessary.
Warning!
G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message Malfunction. Drive to workshop
is
displayed in the multifunction display after
the system self-check, a malfunction in the
system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.

284 OperationDriving instructionsBrakesTo help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only
subject to moderate loads, you should
occasionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.
Refer to the description of the Brake Assist
System (BAS) (
page 88).If the parking brake is released and the
brake warning lamp in the instrument
cluster stays on, the brake fluid level in the
reservoir is too low.
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.
Warning!
G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking ef-
fect. Maintain a safe distance from vehicles
in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an acci-
dent.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.

346 OperationVehicle careLight 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.
!Only use acid-free cleaning materials.
Acid may cause corrosion or damage
the clear coat.
!The vehicle should not be parked for an
extended 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.
Therefore, 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 ap-
proved 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 scour-
ing agents.

350 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 thebulb self-check when switching on the
ignition, have the respective bulb checked
and replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS 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 dis-
play).
The brake system is still functioning nor-
mally but without the ABS available.
If the ABS control unit is malfunctioning,
other systems such as the navigation
system* 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 dis-
play (
page 358).

Have the system checked at an autho-
rized Mercedes-Benz Center as soon as
possible.
Failure to follow these instructions
increases the risk of an accident.
The charging voltage has fallen below ten
volts. The ABS has switched off.
The battery might not be charged suffi-
ciently.

Switch off electrical consumers that are
currently not needed, e.g. seat heating*.

If necessary, have the generator
(alternator) and battery checked.
When the voltage is above this value again,
the ABS is operational again.
