Active height control suspension (AHC) (a) Vehicle height modes "HI" (high) mode- The vehicle height is about 40 mm (1.6 in.) higher at front and about 50 mm (2.0 in.) higher at rear than the normal mode height. This mode is suitable when driving on the bumpy roads and through water. This mode is available when the vehicle speed is under about 30 km/h (19 mph). When the vehicle exceeds the specified vehicle speed, the vehicle height changes to the following: With the four- wheel drive control lever at "H" and at the vehicle speed of 30 km/h (19 mph) or over, the normal mode is automatically selected. With the four- wheel drive control lever at "L" and at the vehicle speed of 50 km/h (30 mph) or over, the vehicle height becomes automatically about 25 mm (1.0 in.) higher than the normal mode height. If the vehicle speed is lowered about 20 km/h (12 mph) or less after that, the high mode automatically resumes. CAUTION This active height control suspension controls the vehicle height depending on the vehicle driving condition. Select your desired height among the "HI" (high), "N" (normal) and "LO" (low) modes with the height select switch. The "HI" (high) or "Extra high" mode should be used for severe off- road driving condition only. Because the vehicle's center of gravity is higher in this setting, the vehicle may become unstable when turning abruptly, resulting in an accident. When the four- wheel drive control lever is put at "L", this mode may change to the extra high mode automatically in accordance with the driving condition. 158
