"HI" (high) height mode
Vehicle height is about 2.0 in. (50 mm) higher at the front, and about
2.4 in. (60 mm) higher at the rear than the normal mode height.
This mode is suitable when driving on bumpy roads or through water.
High height mode is only available when the vehicle speed is under 18
mph (30 km/h).
■ "N" (normal) height mode
The standard vehicle height. This mode is suitable for ordinary driving.
When driving at high speeds, the vehicle height is automatically low-
ered by 0.8 in. (20 mm) in the front and 0.6 in. (15 mm) in the rear, to
ensure excellent aerodynamic characteristics and stability.
If the vehicle speed drops, normal height mode is automatically
resumed.
■ "LO" (low) height mode
Vehicle height is about 2.4 in. (60 mm) lower at the front, and about 1.6
in. (40 mm) lower at the rear than the normal mode height.
This mode allows easy access to the vehicle.
Low height mode is only available when the vehicle is travelling at
7 mph (12 km/h) or less. When the vehicle speed exceeds 7 mph (12
km/h), normal height mode is automatically selected.
