STARTING AND DRIVING When the vehicle's speed exceeds 30 km/h (19 mph), the height control "OFF" indicator light goes out and the electronically modulated air suspension turns on automatically. D If your vehicle gets ditched, turn off the electronically modulated air suspension with the height control switch. Otherwise, the automatic leveling function may cause the vehicle height to change, possibly resulting in further damage to the vehicle. D When disconnecting a trailer, put the vehicle height in the "LO" mode and push the height control switch to turn off the electronically modulated air suspension. Otherwise, the vehicle height may be changed in the automatic leveling function, resulting in unexpected accident. CAUTION D If you drive through water, such as when crossing shallow streams, first check the depth of the water and the firmness of the bottom of the river bed then put the vehicle height into "HI" mode with the height select switch and turn off the electronically modulated air suspension by pushing the height control switch. Drive your vehicle at 30 km/h (19 mph) or slower and avoid deep water. D When jacking up, installing tire chains or tying your vehicle with chains or wires for transportation by a flat bed, be sure to turn off the electronically modulated air suspension with the height control switch and stop the engine. Otherwise, the automatic leveling function may cause the vehicle's height to change, resulting in an unexpected accident. D If your vehicle must be towed, put the vehicle height in the "N" mode and turn off the electronically modulated air suspension. Otherwise, the automatic leveling function may cause the vehicle's height to change, resulting in an unexpected accident. 446
