Useful features
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.System self-check
Initially, after switching on the ignition,
malfunctions 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
Tele Aid – Inoperative
appears in the multifunction display.
iThe SOS button is located in the overhead
control panel (
page 34).
The Roadside Assistance button•
(
page 335) and the Information button¡
(
page 336) are located below the center arm-
rest cover.
!The Tele Aid system utilizes the cellular
network for communication and the GPS (G
lobal
P
ositioning System) satellites for vehicle loca-
tion. 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.
iWhen a Tele Aid call has been initiated, the
COMAND system audio is muted and the select-
ed mode (radio, CD etc.) pauses. The optional
cellular phone (if installed) inserted in cradle
switches off. If you must use this phone, we rec-
ommend that you use it only with the vehicle at a
standstill in a safe location. Remove the phone
from the cradle and place the call. The naviga-
tion* system (if engaged) will continue to run.
The display in the instrument cluster is available
for use, and spoken commands are only avail-
able by pressing the RPT button on the COMAND
system. A pop-up window will appear in the
COMAND system display to indicate that a Tele
Aid call is in progress. After the Tele Aid call has
ended, the optional cellular phone inserted in the
cradle 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
Tele Aid – Inoperative is displayed in
the multifunction display after the system
self-check, a malfunction in the system has
been detected.

349 Operation
Driving instructions
To 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 sub-
jected to moderate loads, you should occa-
sionally 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 103).Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on and an
acoustic warning sounds although the
parking brake is released (
page 437).
Observe additional messages in the multi-
function display that may appear
(
page 469).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Light Truck Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Light Truck Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.
After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so that the air stream will cool down
the brakes faster.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking
maneuvers.
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.
!When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
When using the engine’s braking power, a drive
wheel may not spin for an extended period of
time, e.g. on slippery road surfaces. This may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited
Warranty.
