Front passenger front air bag is deac-
tivated while driving even though an
adult or someone larger than a small
individual is occupying the front pas-
senger seat. Forces acting on the
seat may make the system sense a
decrease in weight.
Stop the vehicle in a safe location as soon as possible and check the
front passenger seat for the following:
Switch off the ignition (
page 33).

Have the front passenger vacate the seat and exit the vehicle.

Keep the seat unoccupied, close the front passenger door and

Monitor the 56indicator lamp on the center console (
page 27) and the mul-
tifunction display in the instrument cluster (
page 24) for the following:
With the seat unoccupied and the ignition turned on,


the 56indicator lamp on the center console should illuminate and remain
illuminated, indicating that the OCS (
page 77) has deactivated the air bag.

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. Depend-
ing on the front passenger classification sensed by the OCS (
page 77), the
56indicator 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 Center.
Warning!
G
If the 56indicator lamp remains
illuminated with an adult occupant on the
front passenger seat even after performing
the above corrective steps, do not have any
passenger use the front passenger seat until
the system has been repaired.

418 Practical hintsTowing the vehicle
!
To be certain to avoid a possibility of
damage to the drivetrain, however, we
recommend the drive shaft be discon-
nected at the rear axle drive flange
(vehicles with 4MATIC: disconnected at
the front and rear axle drive flanges) for
any towing beyond a short tow to a
nearby garage.
Warning!
G
If circumstances require towing the vehicle
with all wheels on the ground, always tow
with a tow bar if:

the engine will not run


there is a malfunction in the power
supply or in the vehicle’s electrical
system
as that will be necessary to adequately
control the towed vehicle.
Prior to towing the vehicle with all wheels on
the ground, make sure the SmartKey is in
starter switch position2.
If the SmartKey is left in starter switch
position0 for an extended period of time, it
can no longer be turned in the switch. In this
case, the steering is locked. To unlock,
remove SmartKey from starter switch and
reinsert.
iTo signal turns while being towed with
the hazard warning flasher in use,
switch on the ignition and activate the
combination switch for the left or right
turn signal in the usual manner – only
the selected turn signal will operate.
Upon canceling the turn signal, the
hazard warning flasher will operate
again.
