262 Driving instructions ! Simultaneously depressing the accelerator pedal and applying the brakes reduces engine performance and causes premature brake and drivetrain wear which is not covered by the Mercedes-Benz Limited Warranty. Hydroplaning Depending on the depth of the water layer on the road, hydroplaning may occur, even at low speeds and with new tires. In heavy rain or when conditions indicate possible hydroplaning: X Reduce vehicle speed. X Avoid track grooves in the road. X Apply brakes cautiously. Off-road driving G Warning! Do not load items on the crossbars. It may cause instability during some maneuvers which could result in an accident. Drive slowly in unknown terrain. This will make it easier to recognize unexpected obstacles and avoid damage to the vehicle. To help avoid the vehicle rolling over, never turn it around on steep inclines. If the vehicle cannot complete the attempted climb, back it down in reverse gear. Do not drive along the side of a slope. The vehicle might otherwise rollover. If in doing so the vehicle begins to show a tendency to roll, immediately steer into a line of gravity (straight up or downhill). Never let the vehicle roll backwards in idle. You may lose control of the vehicle if you use only the service brake. For information on driving downhill, see "Driving downhill". Operation Standing water ! Do not drive through flooded areas. Before driving through water, determine its depth. If you must drive through standing water, drive slowly to prevent water from entering the passenger compartment or the engine compartment. Water in these areas could cause damage to electrical components or wiring of the engine or transmission, or could result in water being ingested by the engine through the air intake causing severe internal engine damage. Any such damage is not covered by the MercedesBenz Limited Warranty. i Select the raised level (Y page 159) before driving through standing water. For more information, see "Driving through water" (Y page 266). G Warning! Sand, dirt, mud and other material having friction property can cause exceptional wear and tear as well as brake failure. Have the brakes checked for dirt build-up and cleaned. There is otherwise a risk that full braking power may not be available in an emergency. G Warning! Please be aware that by raising the vehicle level, the center of gravity also rises. Therefore, always ensure that the vehicle level is as low as possible. With higher ride height the ESP® may activate earlier in certain situations. Read this chapter carefully before you begin off-road travel. Familiarize yourself with the vehicle characteristics and gear changing before you attempt any difficult terrain off-road driving.
