Useful 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
EMERGENCY CALL –
CALL CONNECTED appears in the multi-
function 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.
iWhen a Tele Aid call has been initiated,
the audio system or the COMAND* sys-
tem audio is muted and the selected
mode (radio, tape or CD) pauses. The
optional cellular phone (if installed)
switches off. If you must use this
phone, the vehicle must be parked. Dis-
connect 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 com-
mands are only available by pressing
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.
iThe remote door unlock feature is avail-
able if the relevant cellular phone net-
work is available.
The SOS button will flash and the
message
EMERGENCY CALL –
CALL CONNECTED
will appear in the
multifunction display to indicate
receipt of the door unlock command.
Once the vehicle is unlocked, a
Response Center specialist will
attempt to establish voice contact with
the vehicle occupants.
If the tailgate recessed handle was
pulled for more than 20 seconds
before door unlock authorization was
received by the Response Center, you
must wait 15 minutes before pulling
the tailgate recessed handle again.

240 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 your authorized
Mercedes-Benz Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact your 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 75).
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.

265 Operation
Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times/mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following
messages will appear in the multifunction
display while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:
9Minor service (A)
´ Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared

after ten seconds when you switch on
the ignition or when reaching the
service threshold while driving


after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.

Press the reset button on the
instrument cluster (
page 22).
Service term exceeded
If you have exceeded the suggested
service term, you will see the following
message in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MI (KM)An acoustic signal will also sound.
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.
