A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we
recommend that you pull over to a safe
location and stop before placing or taking a
telephone call. If you choose to use the
telephone while driving, please use the
hands-free device and only use the
telephone when weather, road and traffic
conditions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a
vehicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.

248 Controls in detailUseful features
Remote door unlock
In case you have locked your vehicle unin-
tentionally (e.g. SmartKey inside vehicle),
and the reserve SmartKey is not handy:
Contact the Mercedes-Benz Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
You will be asked to provide your pass-
word which you provided when you
completed the subscriber agreement.

Then return to your vehicle and pull the
tailgate recessed handle for a minimum
of 20 seconds until the SOS button is
flashing.
The message
Connecting call

appears in the multifunction display.
As an alternative, you may unlock the vehi-
cle via Internet using the ID and password
sent to you shortly after the completion of
your acquaintance call.
The Response Center will then unlock your
vehicle with the remote door unlocking
feature.
iThe indicator lamp in the respective
button flashes until the call is con-
cluded. Calls can only be terminated by
a Response Center or Customer
Assistance Center representative
except Roadside Assistance and
Information calls, which can also be
terminated by pressing buttont on
the multifunction steering wheel or the
respective button for ending a
telephone call on the audio system or
COMAND* head unit.
iWhen a Tele Aid call has been initiated,
the audio system or the COMAND*
system audio is muted and the
selected mode (radio or CD) pauses.
The optional cellular phone (if installed)
switches off. If you must use this
phone, the vehicle must be parked.
Disconnect the coiled cord and place
the call. The COMAND* navigation
system (if engaged) will continue to
run. The display in the instrument
cluster is available for use, and spoken
commands are only available by press-
ing the RPT button on the COMAND*
unit. A pop-up window will appear in
the COMAND* display to indicate that
a Tele Aid call is in progress.

258 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
subjected 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.
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 rec-
ommended 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.
!Be very careful not to endanger other
road users when you apply the brakes.
Refer to the description of the Brake
Assist System (BAS) (
page 80).
Warning!
G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.

290 OperationVehicle careWiper blades
Fold wiper arms forward.

Clean the wiper blade inserts with a
clean cloth and detergent solution.Window cleaning

Fold wiper arms forward.

Use a window cleaning solution on all
glass surfaces.
An automotive glass cleaner is
recommended.Light alloy wheels
Mercedes-Benz approved Wheel Care
should be used for regular cleaning of the
light alloy wheels.
If possible, clean wheels once a week with
Mercedes-Benz approved Wheel Care,
using a soft bristle brush and a strong
spray of water.

294 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If a bulb in the instrument cluster fails to
come on during the bulb self-check when switching on ignition, have it 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 brake system is still functioning normally
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
display (
page 301).

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 sufficiently.

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.
