Controls in detail Differential locks Differential locks For more information on off-road driving, see "Off-road driving" ( page 213). Differential locks improve the vehicle's tractive power off-road. Switch on differential locks: for off-road driving to turn the ABS off during off-road driving for driving through water when driving on deep snow and icy or fouled surfaces ! When driving off-road, apply only moderate pressure to the accelerator pedal if the differential locks are switched on. When running on a (single-axle) dynamometer - no matter how briefly - you must: raise the non-driven axle or disconnect its drive shaft and engage the transfer differential lock Otherwise the transfer case can be damaged, which is not covered by the Mercedes-Benz Limited Warranty. Warning! G Never drive on pavement with differential locks engaged. Steering control will be strongly affected with the differential locks activated. The ABS, BAS and ESP are switched off automatically when the transfer case differential lock is activated. ! Do not engage the front axle differential lock when driving around tight corners. This restricts steering ability. 148
