sensitivity.
uSlow continuous wiping
tFast continuous wipingIntermittent wiping
Only switch on intermittent wiping under
wet weather conditions or in the presence
of precipitation.
When you select intermittent wiping, the
rain sensor is activated. The rain sensor
automatically sets a suitable wiping
interval depending on the wetness of the
sensor surface.
Turn the combination switch to
positionU orV.
!Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with wind-
shield washer fluid (
page 65).
!If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.
For safety reasons, stop the vehicle in a safe
location and
remove SmartKey from starter switch
or
turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, starter switch is in
position0, same as with SmartKey
removed from starter switch)
before attempting to remove any blockage.
Remove blockage.
Turn the windshield wipers on again.If windshield wipers fail to function at all in the
combination switch positionU orV,
set the combination switch to the next
higher wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Light
Truck Center
!Do not leave windshield wipers on an inter-
mittent setting when the vehicle is taken to an
automatic car wash or during windshield clean-
ing. Wipers will operate in the presence of water
sprayed on the windshield, and windshield
wipers may be damaged as a result.
!If you have set intermittent wiping, dirt on
the surface of the rain sensor or optical effects
may cause the windshield wipers to wipe in an
undesired fashion. This could then damage the
windshield wiper blades or scratch the windows.
You should therefore switch off the windshield
wipers when weather conditions are dry.

Although independent systems, their
protective functions work in conjunction
with each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The
1indicator lamp in the instrument
cluster (
page 26) comes on when the
ignition is switched on and goes out no
later than a few seconds after the engine
was started.
The SRS components are in operational
readiness if the
1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the
1indicator lamp:
fails to go out not later than approxi-
mately 4 seconds after the engine was
started
does not come on at all
comes on after the engine was started
or while driving

80 Safety and Security
Occupant safety
The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protec-
ted by the fastened seat belts.
The front passenger front air bag will only
be deployed if:
the system senses that the front
passenger seat is occupied
the 59indicator lamp in
the center console is not lit
(
page 85)
the impact exceeds a preset deploy-
ment thresholdSide impact air bags, window curtain
air bags
1Front side impact air bag
2Window curtain air bag
3Rear side impact air bag*
The side impact air bags and window
curtain air bags are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset deploy-
ment threshold
independently of the front air bags
In addition, the window curtain air bags2
are deployed in certain vehicle rollovers.
!Vehicles with BabySmartTM air bag
deactivation system, Canada only:
Do not place objects heavier than 20 lb (9 kg) on
the front passenger seat. This could cause the
front or side impact air bag on the front passen-
ger side to deploy in a crash which exceeds the
system’s deployment threshold.
Warning!G
The pressure sensors for side impact air bag
control are located in the doors. Do not
modify any components of the doors or door
trim panels including, for example, the addi-
tion of door speakers.
Improper repair work on the doors or the
modification or addition of components to
the doors create a risk of rendering the
side impact air bags inoperative or causing
unintended air bag deployment. Work on the
doors must therefore only be performed by
qualified technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

81 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Vehicles with OCS* only:
The front passenger side impact air bag
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy indepen-
dently of the empty seat.Occupant Classification System*
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category.
Warning!G
Only use seat covers which have been test-
ed and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the front side impact air bags or the rear
side impact air bags*. Contact your autho-
rized Mercedes-Benz Light Truck Center for
availability.
iThe system does not deactivate the front
passenger side impact air bag, the window
curtain air bag, and the emergency tensioning
device.

Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
59indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 59indicator
lamp out, the front passenger front air bag is
activated.
When the OCS senses that the front passen-
g e r s e a t o c c u p a n t i s c l a s s i f i e d a s a n a d u l t o r
someone larger than a small individual, the
59indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is
activated.If the 59indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the side impact air
bags.
If the front passenger front air bag is de-
ployed, the rate of inflation will be influ-
enced by:
the rate of vehicle deceleration as
assessed by the air bag control unit
the front passenger’s weight category
as identified by the Occupant Classifica-
tion System (OCS)
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s
instructions.

Instrument cluster
Resetting trip odometer
Make sure you are viewing the trip odome-
ter display (
page 157).
If it is not displayed, press buttonè
orÿ on the multifunction steering
wheel (
page 158) repeatedly until
the trip odometer appears in the multi-
function display.
Press and hold reset button2 in the
instrument cluster (
page 155) until
the trip odometer is reset.
Tachometer
The red marking on the tachometer
(
page 26) denotes excessive engine
speed.To help protect the engine, the fuel supply
is interrupted if the engine is operated
within the red marking.
Outside temperature indicator
The outside temperature is displayed in the
multifunction display (
page 157).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 com-
parison to a thermometer placed next to
the sensor, not by comparison to external
displays (e.g. bank signs etc.).
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.!Avoid driving at excessive engine speeds, as
it may result in serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
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.

Good visibility
Auto-dimming rear view mirrors*
The reflection brightness of the exterior
rear view mirror on the driver’s side and
the interior rear view mirror will respond
automatically to glare when
the ignition is switched on
and
incoming light from headlamps falls on
the sensor in the interior rear view
mirror
The rear view mirror will not react if
the automatic transmission is set to
positionR
the interior lighting is turned onPower folding exterior rear view
mirrors*
Folding the exterior rear view mirrors
in and out automatically
When the corresponding function in the
control system is activated (
page 185):
The exterior rear view mirrors automat-
ically fold in as soon as the vehicle is
locked from the outside.
The exterior rear view mirrors automat-
ically fold out as soon as the vehicle is
unlocked and the driver’s or front pas-
senger door are subsequently opened.
Warning!G
The auto-dimming function does not react if
incoming light is not aimed directly at sen-
sors in the interior rear view mirror.
The interior rear view mirror and the exterior
rear view mirror on the driver’s side do not
react, for example, when transporting cargo
which covers the rear window.
Light hitting the mirror(s) at certain angles
(incident light) could blind you. As a result,
you may not be able to observe traffic con-
ditions and could cause an accident.
Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
!Before you drive the vehicle through an
automatic car wash, fold the exterior rear view
mirrors in. Otherwise they may get damaged.
