Front passenger
airbag
activated
see Oper.’s Man.
Air bag is activated while driving even
though a child, small individual, or object
below the system's weight threshold is on
the front passenger seat, or the front pas-
senger 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 following:
Make sure that there is nothing be-
tween seat cushion and child seat and
check installation of the child seat.

Make sure that no objects applying
supplemental weight onto the seat are
present. The system may recognize
such supplemental weight and sense
that an occupant on the front passen-
ger seat is of a heavier weight than ac-
tually present.

Possible cause
Possible solution
Front passenger
airbag
deactivated
see Oper.’s Man.
Air bag is deactivated while driving even
though an adult or someone larger than a
small individual is occupying the front
passenger 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 following:
Do not lean on armrests or lift yourself
up using handle over the door. This
may make the system sense that an
occupant of a lesser weight than actu-
ally present is on the front passenger
seat.

Re-position yourself.

Sit properly belted in a nearly upright
position with your back against the
seat backrest.
If performing any of the above corrective
steps is successful, the message
Front
passenger airbag activated see
Oper.’s Man.
will appear in the
multifunction display, confirming the situ-
ation has been remedied.

Warning!

Follow recommend inflation pressures.
Do not overinflate tires. Overinflating tires
can result in sudden deflation (blowout) be-
cause they are more likely to become punc-
tured or damaged by road debris, potholes,
etc.
Do not underinflate tires. Underinflated tires
wear unevenly, adversely affect handling
and fuel economy, and are more likely to fail
from being overheated.
Warning!
G
Vehicles with collapsible tire
(CLK 55 AMG only):
Inflate collapsible tire only after the wheel is
properly mounted.
Inflate the collapsible tire using the electric
pump (
page 416) before
lowering the ve-
hicle.
