Information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and
cellular and GPS coverage is available.
The Tele Aid system utilizes the cellular
network for communication and the GPS
(Global P
ositioning S
ystem) satellites for
vehicle location. If either of these signals
are unavailable, the Tele Aid system may
not function and if this occurs, assistance
must be summoned by other means.
!
In order to activate the Tele Aid system, a
subscriber agreement must be completed. To
ensure your system is activated and operational,
please press the ¡button to perform the ac-
quaintance call. Failure to complete either of
these steps may result in a system that is not ac-
tivated.
If you have any questions regarding activation,
please call the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada).
i
Location of the vehicle on a map is only pos-
sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.

If other service calls such as a Roadside
Assistance call or Information call are
active, an Emergency call is still possible.
In this case, the Emergency call will take
priority and override all other active calls.
The indicator lamp in the respective button

gency calls can only be terminated by a Re-
sponse Center or Customer Assistance
Center representative, whereas Roadside

the multifunction steering wheel.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

ap-
pears in the multifunction display.
As an alternative, you may unlock the vehi-
cle via Internet in the “My Tele Aid” section
of “Owner’s Online”, using the ID and pass-
word (USA only).
The Response Center will then unlock your
vehicle with the remote door unlocking
feature.
i
When a Tele Aid call has been initiated, the
audio system is muted and the selected mode
(radio or CD) pauses. The mobile phone (if con-
nected) switches off. If you must use this phone,
we recommend that you use it only with the ve-
hicle at a standstill in a safe location. The multi-
function display in the instrument cluster is
available for use. After the Tele Aid call has end-
ed, the optional mobile phone switches on again.
A PIN entry might be necessary.
i
The 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 multifunc-
tion display to indicate receipt of the door unlock
command.
Once the vehicle is unlocked, a Response Center
specialist may attempt to establish voice contact
with the vehicle occupants.
If the trunk recessed handle was pulled for more
than 20 seconds before door unlock authoriza-
tion was received by the Response Center, you
must wait 15 minutes before pulling the trunk
recessed handle again.

There are malfunctions, but the

is operating normally.

Contact an authorized Mercedes-Benz Center
immediately.

Parking Brake
You are driving with the parking

Brake Wear
The brake pads have reached
their wear limit.

Have the brake pads replaced as soon as pos-
sible.
!
Brake pad thickness must be visually
checked by a qualified technician at the intervals
specified in the Maintenance Booklet.
Excessive load on the brake system causes in-
creased wear of brake pads and brake disks. If
the brake pads have to be replaced multiple
times within one maintenance service interval,
the brake disks must be checked. Observe the
information given in the Maintenance Booklet
and contact an authorized Mercedes-Benz
Center.
Warning!
G
Have brake pad replacement and other work
on the electro-hydraulic brake system car-
ried out by qualified technicians only. Con-
tact your Mercedes-Benz Center for further
information. The electro-hydraulic brake
system must be deactivated prior to working
on the system. High pressure is intermit-
tently built up in the system as part of its
automatic self-test. In addition, the system
is automatically activated when the vehicle
is unlocked by remote control, when the
driver or passenger door is opened, when
the SmartKey in the starter switch is turned
to position1, when the brake pedal is
depressed or when the parking brake is
released.
Failure to deactivate the system prior to
maintenance will cause brake pistons to
extend and brake fluid to leak, which may
result in injuries (contusions and acid
burns), see “Electro-hydraulic brake sys-
tem” (
page 87).

374 Practical hintsTowing the vehicleWarning!
G
The brake system requires electrical power
to operate.
A malfunction in the vehicle’s power supply
or electrical system may impair brake sys-
tem operation and switch it into its emer-
gency operation mode. To brake, the driver
must then apply significantly greater brake
pedal pressure and depress the pedal much
further to obtain the expected braking ef-
fect. If necessary, apply full pressure to the
brake pedal. Brakes are only applied to the
front wheels. Stopping distance is in-
creased! Adapt your driving style according-
ly. For more information, see
“Electro-hydraulic brake system”
(page 87).
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
!
Towing of the vehicle should only be done
using the properly installed towing eye bolt.
Never attach tow cable, tow rope or tow rod to
the vehicle chassis, frame or suspension parts.
i
To signal turns while being towed with the
hazard warning flasher in use, turn SmartKey in
starter switch to position2 and activate the
combination switch for the left or right turn
signal in the usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard
warning flasher will operate again.
i
When towing the vehicle with all wheels on
the ground, please note the following:
With the automatic central locking activated and
the SmartKey in starter switch position2 the
vehicle doors lock if the left front wheel as well
as the right rear wheel are turning at vehicle
speeds of approximately 9 mph (15 km/h) or
more.
To prevent the vehicle door locks from locking,
deactivate the automatic central locking
(
page 139) and switch off the tow-away alarm
(page 95).
i
The gear selector lever will remain locked in
park positionP and the SmartKey will not turn in
the starter switch if the battery is disconnected
or discharged. See notes on the battery
(
page 370).
