Operation Driving instructions Returning from off-road driving Warning! Off-road driving increases strain on the vehicle. Clean the front and rear license plate. 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. Check tires for possible damage. Inspect vehicle underbody, oil pan, brake hoses, etc., as well as vehicle underbody for possible damage. Check for brush or branches caught in the underbody. G If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the roadway. Inspect the tires and under the vehicle for possible damage. If the vehicle or tires appear unsafe, have it towed to the nearest Mercedes-Benz Light Truck Center or tire dealer for repairs. Damage to the vehicle may influence driving comfort and pose the risk of accident to you and other drivers. 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 off the off-road driving program ( page 280) or the LOW RANGE mode* ( page 203). Switch off the DSR ( page 276). Set the differential locks* to AUTO ( page 207). Lower the vehicle back to a level suitable for road conditions, e.g. Highway/High-speed level ( page 281). Clean all exterior lamps and check for possible damage. ! Brush or branches 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. 365
