06 06.07 NOTICE z If the vehicle height is changed frequently when the vehicle is heavily loaded, the compressor may overheat, causing the vehicle height adjustment operation to stop. z Before you lower the vehicle height with the height select switch, check under the vehicle to make sure nothing to damage the vehicle or no one to be injured is there and that the underbody of the vehicle does not touch the ground. z After unloading, the height of a vehicle equipped with the rear height control air suspension becomes slightly higher than the normal vehicle height. Take sufficient care where the overhead height is restricted. z Do not select the "LO" mode in the bumpy roads. If the underbody of the vehicle touches the rugged road surface, the vehicle may be damaged. (d) Turning off the rear height control air suspension To turn off the rear height control air suspension with the vehicle stopped, push the "HEIGHT CONTROL OFF" switch. The height control "OFF" indicator light comes on and the vehicle height is fixed in the same mode as the height control switch is pushed. This status is memorized in the system even after the engine is stopped. If you push the switch again, the height control "OFF" indicator light goes out and the rear height control air suspension is turned on. Even after the rear height control air suspension is turned off with the "HEIGHT CONTROL OFF" switch, if the vehicle speed exceeds 30 km/h (19 mph), the rear height control air suspension automatically selects the "N" mode.
