Important! During off-road driving a special low range system for antilock brake system (ABS) and four-wheel electronic traction system (4-ETS+) are operational with transmission in the LOW RANGE mode. In the low range mode the electronic stability program (ESP) operates in a traction improving fashion specifically adapted for off-road driving. At speeds below 27 mph (45 km/ h) the ESP assists in over-/ understeering, thus improving vehicle tracking. If one or more tires lose traction while driving downhill (accelerator released), the 4-ETS+ engages and the warning lamp v, located in the speedometer dial, starts to flash. When applying the service brakes at speeds below approximately 18 mph (30 km/h), the front wheels are locked cyclically to shorten the braking distance (dig in effect). This affects steering the vehicle. Notes: Driving off or driving up to 3 mph (5 km/ h) with the service brakes applied lightly (to reduce drive wheel spin), the 4-ETS+ remains engaged. Driving with the service brakes applied lightly at vehicles speeds above 3 mph (5 km/h), the 4-ETS+ will not engage. If the indicator lamp blinks fast, one or more switching conditions were not observed, or the LOW RANGE mode is defective. In the case of a defective in the LOW RANGE mode the transmission shifts in the usual manner. It is not possible to switch on the LOW RANGE mode. Have the transmission checked at your authorized Mercedes-Benz Light Truck Center as soon as possible.
