Tachometer
To help protect the engine, the fuel supply
is interrupted if the engine is operated
above its specified limit.
Outside temperature indicator
When moving the vehicle into colder ambi-
ent temperatures (e.g. when leaving your
garage), you will notice a delay before the
lower temperature is displayed.
A delay also occurs when ambient temper-
atures rise. This prevents inaccurate tem-
perature indications caused by heat
radiated from the engine during idling or
slow driving.

Warning!
G
The outside temperature indicator is not de-
signed to serve as an ice-warning device and
is therefore unsuitable for that purpose.
Indicated temperatures just above the freez-
ing point do not guarantee that the road sur-
face is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
iTo set the clock by a single hour or a
few minutes, turn knob2 just a few de-
grees in the direction indicated for
hours or minutes.

114 Controls in detailAutomatic transmissionUpshifting
Briefly press the selector lever to the
right in the D+direction.
The transmission will shift from the cur-
r e n t g e a r t o t h e n e x t h i g h e r g e a r a s p e r -
mitted by the shift program. This action
simultaneously extends the gear range
of the transmission.Canceling gear range limit

Press and hold the selector lever in the
D+direction until D reappears in the
tachometer display field.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D– direction.
The transmission will automatically se-
lect the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more
gears.
Gear ranges
With the selector lever in positionD, you
can limit the transmission’s gear range by
pressing the lever to the left (D-), and re-
verse the gear range limit by pressing the
lever to the right (D+).
The selected gear range will appear in the
tachometer display field. If you press on
the accelerator when the engine has
reached its rpm limit, the transmission will
upshift beyond any gear range limit
selected.
iTo avoid overrevving the engine when
the selector lever is moved to the D– di-
rection, the transmission will not shift
to a lower gear if the engine’s max.
speed would be exceeded.

!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using the

(Telematic Alarm Identification on
Demand)
The Tele Aid system consists of three
types of response:

automatic and manual emergency


roadside assistance and

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 using the volume control on
the MCS unit.

Emergency calls
An emergency call is initiated automatical-
ly:

following an accident in which the
emergency tensioning detractors
(ETDs) or airbags deploy,


if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (
page 78) and tow-away alarm
(
page 79).
An emergency call can also be initiated
manually by opening the cover next to the
inside rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See below for instructions on
initiating an emergency call manually.
Warning!
G
The Tele Aid control unit is located under
the front passenger seat. If there is accumu-
lation of water or other liquid in this area,
the Tele Aid control unit could suffer an
electrical short circuit making the system in-
operative. In this case the indicator lamp in
the SOS button will not illuminate during or
will remain illuminated after the system
self-check. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.
If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button do not come on dur-
ing the system self-check or if any of these
indicators remain illuminated constantly in
red and/or the message
TELE AID - VIS-
IT WORKSHOP
is displayed in the MCS dis-
play after the system self-check, a
malfunction in the system has been detect-
ed.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.
