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.

In winter operation, the maximum effectiveness of the 
antilock brake system (ABS), the four wheel electronic 
traction system (4-ETS), the electronic stability program 
(ESP), and electronic brake booster (EBB) can only be 
achieved with M+S rated radial-ply tires and / or snow 
chains recommended by Mercedes-Benz. Snow chains 
maximize performance.
For driving instructions using snow chains see 
page 222.Deep water
Caution!
Do not drive through flooded areas or water of unknown 
depth. Before driving through water, determine its 
depth. It should not be deeper than approximately 
20 inches (50 cm).
If you must drive through deep water, drive slowly to 
prevent water from entering the engine compartment or 
passenger compartment, being ingested by the air 
intake, possibly causing damage to electrical 
components or wiring, to engine or transmission that is 
not covered by the Mercedes-Benz Limited Warranty.
