Operation Driving instructions Off-road driving increases strain on the vehicle. We recommend that you inspect the vehicle for possible damage after each off-road trip. Recognizing any damage and a subsequent timely repair reduces the chance of a possible breakdown or accident later on. Proceed as follows: Switch the transfer case in position HIGH ( page 141). Disengage differential locks ( page 146). Remove excessive dirt from tires, wheels, wheel housings, and underbody. For instance, after driving in mud, clean the radiator, chassis, engine, brakes, and wheels from extreme dirt using a strong jet of water. Inspect frame, oil pan, brake hoses, etc., as well as vehicle underbody for possible damage. Check tires for possible damage and remove foreign objects. Clean all exterior lamps and conduct a brake test. Clean all exterior lamps and check them for possible damage. Check for brush or branches caught in the undercarriage. They could increase the possibility of a fire, as well as cut fuel and/or brake lines, puncture rubber bellows of the axles or drive shafts. After continued operation in mud, sand, water or other dirty conditions, clean the brake discs, wheels, brake pads and check and clean axle joints. Conduct a brake test. 1 Control and operation of radio transmitters COMAND, radio and telephone* Warning! G Do not forget that your primary responsibility is to drive the vehicle safely.
