71 Safety and Security
Occupant safety
Occupant Classification System
The O
ccupant Classification System (OCS)
automatically turns the passenger front air
bag and passenger-side knee bag on or off
based on the classified occupant weight
category determined by weight sensor
readings from the 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
leaning on armrests), the OCS may not be
able to properly approximate the
occupant’s weight category. Both driver and the passenger should al-
ways use the 75 indicator
lamp as an indication of whether or not the
passenger is properly positioned
(
page 76).
Warning!G
Only use seat covers which have been
tested and approved by Mercedes-Benz for
your vehicle model. Using other seat covers
may interfere with or prevent the deploy-
ment of the head-thorax air bags. Contact
an authorized Mercedes-Benz Center for
availability.
iThe system does not deactivate the
head-thorax air bag and the emergency tension-
ing device.
iIf the seat, including the trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.

Anti-theft systems
Arming the alarm system
Lock your vehicle with the SmartKey.
The turn signal lamps flash three times
and an acoustic warning sounds three
times (if equipped and feature
activated) to indicate that the alarm
system is armed.
The indicator lamp in the central lock-
ing switch starts flashing (
page 103).Disarming the alarm system
Unlock your vehicle with the SmartKey.
The turn signal lamps flash once and
an acoustic warning sounds once (if
equipped and feature activated) to
indicate that the alarm system is
disarmed.
Canceling the alarm
To cancel the alarm:

someone attempts to raise the vehicle.
iIf the turn signal lamps do not flash three
times and no acoustic warning sounds three
times (though equipped and feature activated), a
door or the trunk lid may not be properly closed:
Close the respective element and lock the
vehicle again.
iThe tow-away protection alarm is triggered,
for example, if the vehicle is lifted on one side.
If the alarm stays on for more than 30 seconds,
a call to the Response Center is initiated auto-
matically by the Tele Aid* system (
page 261),
provided Tele Aid* service was subscribed to
and properly activated, and that necessary cellu-
lar service and GPS coverage are available
(
page 261).

cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of
the vehicle and do not stand near the vehicle
