AIR BAG SAFETY PRECAUTIONS
Observe these precautions when servicing the air bag system:
When working around SRS components and before any repairs are performed, disable air bag system. See
DISABLING & ACTIVATING AIR BAG SYSTEM
.
Before straightening any damage to body, or before performing electrical arc-welding, disable air bag
system. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
Always wear safety glasses and gloves when handling a deployed air bag module. Air bag module may
contain sodium hydroxide deposits which are irritating to the skin.
Always use control module and impact sensors made by same manufacturer. Using components produced
by different manufacturers could cause accidental air bag or ETR deployment.
DO NOT repair any portion of SRS wiring harness.
If any SRS component is dropped from a height greater than 1.6 feet (0.5 m), it must be replaced.
If SRS components show signs of damage, they must be replaced.

Warning!
G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could

engine is running. You should therefore nev-
er turn off the engine while driving.

or tires / wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
o per at i ng s a fet y of yo ur veh ic l e. I f y ou f ee l a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires / wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Light
Truck Center or other qualified maintenance
or repair facility for further inspection or re-
pairs.
