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.• Do not pass belts over sharp edges.• Do not make any modification that could 
change the effectiveness of the belts.• 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.
• 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”.• 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, or front door trim panels, and 
installation of additional electrical / electronic 
equipment on or near “SRS” components and 
wiring. Keep area between airbags and 
occupants free of objects (e.g. packages, 
purses, umbrellas, etc.).
