This mode is suitable when driving on the bumpy roads and through water. However, when the vehicle speed exceeds about 30 km/h (19 mph) or over in the "HI" mode, the "N" mode is automatically selected. CAUTION The "HI" mode should be used for severe off-road driving condition only. As the vehicle's center of gravity is higher in this setting, the vehicle may become unstable when turning abruptly resulting in accident.

"LO" (low) mode: The vehicle height is about 20 mm (0.8 in.) lower at the rear than the "N" mode height. This mode allows you easy access to the vehicle (getting in and out) and easy loading and unloading operation. This mode is available when the vehicle speed is under about 12 km/h (7 mph).
