proximately 6 seconds.

senses the front passenger seat as being
empty, the
5/indicator lamp will
illuminate and not go out.
Warning!G
If the =indicator lamp and the
5/indicator lamp are lit at the same
time, there is a malfunction in the Occupant
Classification System. The front passenger
front air bag will be deactivated in this case.
Have the system checked as soon as possi-
ble by qualified technicians. Contact an au-
thorized Mercedes-Benz Center.
Only have the seat repaired or replaced at
an authorized Mercedes-Benz Center.
In order to ensure proper operation of the
air bag system and OCS:

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

While seated, an occupant should not
position him/herself in such a way as to
cause the occupant’s weight to be lifted
from the seat bottom as this may result
in the OCS being unable to correctly ap-
proximate the occupant’s weight
category.

Read and observe all warnings in this
chapter.Warning!G
If the 5/indicator lamp should not il-
luminate, the system is not functioning. You
must see an authorized Mercedes-Benz
Center before seating any child on the front
passenger seat.

Warning!G
All seat, head restraint adjustments, as well
as fastening of seat belts, must be done be-
fore the vehicle is put into motion.
Warning!G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat backrest and
seat belts provide the best restraint when
the wearer is in a position that is as upright
as possible and seat belts are properly posi-
tioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
Observe the following points:

Adjust the seat backrest until your arms
are slightly angled when holding the
steering wheel.

Adjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The po-
sition should be as far back as possible
with the driver still able to properly oper-
ate controls.

Adjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports
the back of the head at eye level.

Never place hands under the seat or
near any moving parts while a seat is be-
ing adjusted.
Failure to do so could result in an accident
and/or serious personal injury.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or SmartKey with
KEYLESS-GO* (Canada only) removed from
the starter switch or the SmartKey with
KEYLESS-GO* (Canada only) removed from
the vehicle, the power seats can be
operated.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. A child’s unsupervised access to a
vehicle could result in an accident and/or
serious personal injury.

Releasing seat belts
Press the seat belt release button

wind the seat belt by guiding the latch
plate.
Warning!G
Do not turn off the engine before the vehicle
has come to a complete stop. With the en-
gine not running, there is no power assis-
tance for the brake and steering systems. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to brake and steer the vehicle.
iIn an emergency you can turn off the engine
while driving by pressing and holding the
KEYLESS-GO start/ stop button for approxi-
mately 3 seconds.
!Make sure the seat belt retracts fully so that
the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limited Warranty.
Damaged seat belts must be replaced. Contact
an authorized Mercedes-Benz Center.
