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 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.

(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.

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
trunk 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.
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.
iThe remote door unlock feature is
available if the relevant cellular phone
network is available.
The SOS button will flash and the
message
Connecting call
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 trunk 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
trunk recessed handle again.

266 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.
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.
!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 78).
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.
