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.

If you push the switch again, the height control "OFF" indicator light goes out and the active height control suspension is turned on. CAUTION If you drive through deep water over about 500 mm (20 in.) in depth, put the vehicle height in the HI (High) mode with the active height select switch and then turn off the active height control suspension by pushing the height control switch. Drive your vehicle at 30 km/h (19 mph) or lower speed. NOTICE
