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.

76 Safety and Security
Occupant safety
Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal
impacts (front air bags), side impacts (side
impact air bags and window curtain air bags)
or rollovers (window curtain air bags).
However, no system available today can
completely eliminate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
Warning!G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body
(
page 54).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a position that is as
upright as possible with your back
against the seat backrest.

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any
problems, please see an authorized
Mercedes-Benz Light Truck Center.

Do not lean your head or chest close to
the steering wheel or dashboard.

Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.

Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

77 Safety and Security
Occupant safety

Always sit as upright as possible, prop-
erly use the seat belts and use an appro-
priately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.

Vehicles with BabySmartTM air bag
deactivation system, Canada only:
Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmartTM
system installed in the vehicle to deacti-
vate the front passenger front air bag
when it is properly installed. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, seri-
ous or fatal injury will result.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both,
front side impact air bags or the rear side
impact air bags*, there is a possibility for a
side impact air bag related injury if occu-
pants, especially children, are not properly
seated or restrained when next to a side
impact air bag which needs to deploy rapidly
in a side impact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible,
properly use the seat belts, and for all
children 12 years old and under, use an
appropriately sized infant restraint,
toddler restraint, or booster seat recom-
mended for the size and weight of the
child.
(2) Always wear seat belts properly.
iAir bags are designed to deploy only in
certain frontal impacts (front air bags), and in
side impacts (side impact and window curtain air
bags) which exceed preset thresholds, and in
certain rollovers (window curtain air bags). Only
during these events will they provide their sup-
plemental protection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not deploy. The driver and passenger will then be
protected to the extent possible by a properly
fastened seat belt. A properly fastened seat belt
is also needed to provide the best possible pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.

Safety guidelines for the seat belt,
emergency tensioning device and
air bag
Warning!G

Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Only use belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.

Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced.

Do not pass belts over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the belts.

Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or
removing any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Do n o t h a ng i te ms su ch as c o at ha n ger s
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when the window curtain air bag is
deployed.

Air bag system components will be hot
after an air bag has inflated. Do not
touch.

Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from your authorized Mercedes-Benz
Light Truck Center.

Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other potentially more serious injuries
resulting from air bag deployment.

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

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.

Warning!G
The BabySmartTM air bag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.

90 Safety and Security
Occupant safety
Warning!G
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.

Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag, pas-
senger front air bag, side impact air
bags, window curtain air bags for side
windows), ETD (seat belt emergency
tensioning device), and front seat knee
bolsters. The system is designed to en-
hance the protection offered to properly
belted occupants in certain frontal (front
air bags and ETD) and side (side impact,
window curtain air bags and ETD) im-
pacts which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).

Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.

Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, SmartKeys, etc., as
these might cause injuries.

Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.

Never use a seat belt for more than one
person at time. Do not fasten a seat belt
around a person and another person or
other objects.

Belts should not be worn twisted. In a
crash, you would not have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.

Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.

When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.
