Te ch n i c a l

cluster displayPractical hints Car care Index Important!
The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the key in starter switch to
position 1 or 2. If no fault is detected, the lamp will go
out after approximately 5 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 5 seconds or if it comes on thereafter,
a malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckle, emergency tensioning
retractors, seat sensor.
Initially, when the key is turned from starter switch
position 0 to positions 1 or 2, malfunctions in the
crash-sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 5 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Light Truck Center immediately.In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck Center immediately to
have the system checked; otherwise the “SRS” may
n ot be a ct ivated when need ed in an ac c i den t, whi ch
could result in serious or fatal injury, or it might
deploy unexpectedly and unnecessarily which
could also result in injury.

cluster displayPractical hints Car care Index Inside rear view mirror
Manually adjust the mirror.
Automatic antiglare night position
With the key in starter switch position 2 and the
automatic antiglare function activated, the mirror
reflection brightness responds to changes in light
sensitivity.Notes:
With gear selector lever in position “R”, or with the
interior lamps (except cargo compartment lamp)
switched on, the mirror brightness does not respond to
changes in light sensitivity.
The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
mirror.
The antiglare function will not react for example, if the
cargo area is fully loaded.
Wa r n i n g !
In the case of an accident liquid electrolyte may
escape the mirror housing when the mirror glass
breaks.Electrolyte has an irritating effect. Do not allow the
liquid come into contact with eyes, skin, clothing,
or respiratory system. In cases it does, immediately
flush affected area with water, and seek medical
help if necessary.

89 Instrument cluster
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Outside temperature indicator (12)
The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).Adaption to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stop-
and-go or moderate, constant driving) and amount of
temperature change.
Note:
The unit for the temperature indicator display can be set
in the individual setting menu “INSTRUMENT
CLUSTER” – “TEMP. INDICATOR” on page 110.
Wa r n i n g !
The outside temperature indicator is not designed
to serve as an Ice-Warning Device and is therefore
unsuitable for that purpose. Indicated
temperatures just above the freezing point do not
guarantee that the road surface is free of ice.

Single wipe without washer fluid
(select only if windshield is wet).

I Intermittent wiping
One initial wipe, pauses between wipes are
automatically controlled by a rain sensor
monitoring the wetness of the windshield. This
will not occur with a front door open.
Notes:
With switch in this position, one wipe occurs
when turning the electronic key in starter switch
from position 0. However, this might cause
scratches in a dry windshield. Turn combination
switch to Off position before turning the
electronic key in starter switch from position 0.
Do not leave in intermittent setting when vehicle
is taken to an automatic car wash or during
windshield cleaning. Wipers will operate in
presence of water spray at windshield, and
wipers may be damaged as a result.
II Normal wiper speed
III Fast wiper speed

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.
