242 Controls in detailPower tilt/sliding sunroof*Warning!
G
When closing the tilt/sliding sunroof, make
sure that there is no danger of anyone being
harmed by the closing procedure.
If the tilt/sliding sunroof encounters an ob-
struction that blocks its path in a circum-
stance where you are closing the tilt/sliding
sunroof by moving the tilt/sliding sunroof
switch past the resistance point, or by
pressing and holding button‹ on the
SmartKey, by pressing and holding the lock
button (vehicles with KEYLESS-GO*) on the
door handle, the automatic reversal function
will not operate.
The opening/closing procedure of the
tilt/sliding sunroof can be immediately halt-
ed by releasing the switch or, if the switch
was moved past the resistance point and re-
leased, by moving the switch in any direc-
tion.
The tilt/sliding sunroof is made out of glass.
In the event of an accident, the glass may
shatter. This may result in an opening in the
roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts prop-
erly as entire body parts or portions of them
may protrude from the passenger compart-
ment.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock your vehicle. Do not leave children un-
attended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-
cle equipment can cause an accident
and/or serious personal injury.!
To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(
page 478).
i
When the tilt/sliding sunroof is open, reso-
nance noises may result in addition to the usual
wind noises. They are caused by minimal pres-
sure changes in the passenger compartment. To
reduce or eliminate these noises, change the po-
sition of the tilt/sliding sunroof or open a side
window slightly.
i
You can also open or close the tilt/sliding
sunroof using the SmartKey or the
KEYLESS-GO* function, see “Summer opening
feature” (
page 239) and see “Convenience
closing feature” (
page 239).
i
Depending on the current position, the
tilt/sliding sunroof may also open or close when
the air recirculation button: on the control
panel of the climate control (
page 208) or
automatic climate control* (
page 222) is
pressed and held.

The front passenger
front air bag off indicator
lamp does not illuminate
and/or does not remain
illuminated with the
weight of a typical
12-month-old child in a
standard child restraint or
less on the front passen-
ger seat.
The system is malfunction-
ing.
Make sure there is nothing between seat cushion and
child seat and check installation of the child seat.
Make sure no objects applying supplemental weight
onto the seat are present.
Make sure no objects which apply forces to the seat are
present (e.g. objects such as books, briefcases etc.
lodged behind or around the seat, head restraints push-
ing against roof etc.). The system may recognize such
forces as supplemental weight.
If the front passenger front air bag off indicator lamp re-
mains out, have the system checked as soon as possible
by an authorized Mercedes-Benz Light Truck Center. Do
not transport a child on the front passenger seat until
the system has been repaired.
Also note any messages in the multifunction display and
follow corrective steps (
page 440).
Warning!

If the59indicator lamp does
not illuminate or remains out with the
weight of a typical 12-month-old child in a
standard child restraint or less on the front
passenger seat, do not transport a child on
the front passenger seat until the system
has been repaired.

cause/consequence
Possible solution
Front passenger airbag
enabled
See Operator’s Manual
Front passenger front air bag
is activated while driving even
though a child, small
individual, or object below
the system’s weight thresh-
old is on the front passenger
seat, or the front passenger
seat is empty. Objects on the
seat or forces acting on the
seat may make the system
sense supplemental weight.
Stop the vehicle in a safe location as soon as possible and check the front
passenger seat for the following:
Apply the parking brake (
page 65).
Switch off the ignition (
page 40).
Remove child and child restraint from front passenger seat and properly
secure the child in rear seat employing the child restraint if necessary.
Remove any other items from on and around the front passenger seat
and make sure the storage bag on the back of the front passenger seat
is empty.
Make sure that no objects which apply forces to the seat are present
(e.g. objects such as books, briefcases etc. lodged behind or around the
seat, head restraints pushing against roof etc.). The system may recog-
nize such forces as supplemental weight and sense that an occupant on
the front passenger seat is of a greater weight than actually present.
Keep the seat unoccupied, close the front passenger door and switch
on the ignition (
page 40).

Possible
cause/conse-
quence
Possible solutionMonitor the 59indicator lamp on the center console (
page 89) and
the multifunction display in the instrument cluster (
page 26) for the following:
With the seat unoccupied and the ignition turned on,
the 59indicator lamp on the center console should illuminate and
remain illuminated, indicating that the OCS (
page 85) has deactivated the air
bag.
the message
Front passenger airbag enabled See Operator’s Manual
or the
message
Front passenger airbag disabled See Operator’s Manual
should not
appear in the multifunction display at any time the seat is unoccupied. Wait at last
60 seconds for the system to complete the necessary check cycles and to make
sure neither message appears in the multifunction display.
If above conditions are met, you can occupy the front passenger seat again.
Depending on the front passenger classification sensed by the OCS (
page 85),
the59indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the system
checked as soon as possible by an authorized Mercedes-Benz Light Truck Center.
Warning!
G
If the 59indicator lamp
remains out even after performing the above
corrective steps, do not have any children
12 years old and under and other small
individuals use the front passenger seat
until the system has been repaired.
507 Practical hints
Battery
Battery
The battery is located under the front
passenger seat.
The battery should always be sufficiently
charged in order to achieve its rated ser-
vice life.
If you use your vehicle mostly for
short-distance trips, you will need to have
the battery charge checked more
frequently.
When replacing the battery, always use
batteries approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, consult an
authorized Mercedes-Benz Light Truck
Center about steps you need to observe.Batteries contain materials that can harm
the environment if disposed of improperly.
Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.i
Mercedes-Benz recommends to have the
battery replaced at an authorized
Mercedes-Benz Light Truck Center.
Warning!
G
Observe all safety instructions and precau-
tions when handling automotive batteries.
Risk of explosion.
Fire, open flames and smoking
are prohibited when handling

ing, especially gloves, apron and
faceguard.
Wear eye protection.
