The Tele Aid system
(Tele

dentification on
D
emand)
The Tele Aid system consists of three
types of response:

automatic and manual emergency


roadside assistance


information
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the Modular COMAND System or on the
multifunction steering wheel. To raise, turn
the rotary volume control on Modular
COMAND System clockwise or press
buttonæ on the multifunction steering
wheel. To lower, turn the rotary volume
control on Modular COMAND System con-trol counterclockwise or press
buttonç on the multifunction steering
wheel.

To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.iThe SOS button is located in the over-
head control panel.
The Roadside Assistance button•
and the Information button¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal P
ositioning S
ystem) satel-
lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
iWhen a Tele Aid call has been initiated,
the Modular COMAND System audio is
muted and the selected mode (radio,
CD etc.) pauses. The optional cellular
phone (if installed) inserted in cradle
switches off. If you must use this
phone, we recommend 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 navi-
gation* system (if engaged) will contin-
ue 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 Modular
COMAND System. A pop-up window
will appear in the Modular COMAND
System display to indicate that a Tele
Aid call is in progress. After the TeleAid
call has ended, the optional cellular
phone inserted in the cradle switches
on again. A PIN entry might be neces-
sary.

351 Operation
Tires and wheels
Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System* (Advanced TPMS*)The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display.The present inflation
pressures are displayed only after a few
minutes’ travel time.

Switch on the ignition (
page 34).

Press thej or kbutton until
the current inflation pressures for each
tire appear in the multifunction display.
iThe Advanced T
ire P
ressure M
onitoring
S
ystem* (Advanced TPMS*) is
equipped with a combination low tire
pressure/TPMS malfunction telltale in
the instrument cluster (
page 24). De-
pending on how the telltale illuminates,
it indicates a low tire pressure condi-
tion or a malfunction in the TPMS sys-
tem itself:


If the telltale illuminates continu-
ously, one or more of your tires is
significantly under-inflated. There is
no malfunction in the TPMS.


If the telltale flashes for 60 seconds
and then stays illuminated, the
TPMS system itself is not operating
properly.
iPossible differences between the read-
ings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and
the vehicle’s control system can occur.
Usually the readings issued by the con-
trol system are more precise.
iWhen the message
Tire pressure
display appears after driving sev-
eral minutes
appears in the display,
the individual inflation pressure values
are matched with the tires. The individ-
ual values are displayed after a few
minutes driving.
iWith a spare wheel without wheel sen-
sor mounted, the system may still indi-
cate the tire inflation pressure of the
removed wheel for some minutes. If
this happens, keep in mind that the in-
dicated value where the spare wheel is
mounted does not reflect the actual
spare tire inflation pressure.

372 OperationMaintenanceClearing the maintenance service indicator
The maintenance service indicator is auto-
matically cleared after ten seconds when
you switch on the ignition or when reach-
ing the service threshold while driving. You
can also clear it yourself.
Press reset button on the instrument
cluster (
page 24).
Maintenance service term exceeded
If you have exceeded the suggested main-
tenance service term, you will see the fol-
lowing message in the multifunction
display:Service A exceeded by XXXXX miles (km)
Service A exceeded by XXX days
Service A exceeded by X dayIn addition, a signal sounds when the mes-
sage appears.
Any authorized Mercedes-Benz Light Truck
Center will reset the maintenance service
indicator following a completed mainte-
nance service.
Calling up the service indicator
Switch on the ignition (
page 34).
The standard display of the control sys-
tem appears (
page 156).

Press buttonk orj on the mul-
tifunction steering wheel until the
maintenance service indicator with the
service symbol9 and the service
deadline appears in the multifunction
display.iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicatorN.

382 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.Problem
Possible cause
Suggested solution
-
The yellow ABS indicator lamp
comes on while the engine is
running.
ABS has detected a malfunction and has
switched off. The BAS, ESP
®, and 4-ETS are
also switched off (see messages in multifunc-
tion 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
multifunction display (
page 395).

Have the system checked at an
authorized Mercedes-Benz Light
Truck 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 the battery checked.
When the voltage is above this value
again, the ABS is operational again.
