tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Light Truck Center.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Do not use handles above doors for placing
such items as coat hangers etc.
• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical /
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).•An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.• In addition, through improper work there is a
risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Light Truck
Center.

To signal minor directional changes, such as changing
lanes on a highway, move combination switch briefly to
the point of resistance only and release. The turn
signals blink three times.
To operate the turn signals continuously, move the
combination switch past the point of resistance (up or
down). The switch is automatically canceled when the
steering wheel is turned to a large enough degree.
Turn signal failure
If one of the turn signals fails, the turn signal indicator
system flashes and sounds at a faster than normal rate.
