2-4. Using other driving systems

When luggage mode is selected

If the vehicle begins to move while still in luggage mode, the vehicle will automati-

cally change to “N” mode once speed exceeds 5 mph (8 km/h). Even if vehicle

speed is reduced below 5 mph (8 km/h), the vehicle height will not automatically

return to luggage mode.

Operating sound of the air suspension

When the vehicle height is lowered, such as when entering and loading the vehicle,

or when the height selector switch is operated, the sound of the compressor oper-

ating or the mode changing may be heard. This does not indicate a malfunction.

Automatic leveling function

Regardless of the number of occupants and the luggage load, vehicle height in any

mode is always adjusted to a fixed height by the automatic leveling function.

Vehicle height mode change time

If the height control is operated continuously to lower the vehicle, the suspen-

sion air tank may become full, causing operation of the vehicle height lowering

control to become slow.

To protect the compressor, the system will only raise the vehicle for a total of

100 consecutive seconds. If it takes longer than this to reach the selected

height, operation may be suspended shortly and then restart. However, it may

not be possible to change the vehicle's height mode at this time.

The electronically modulated air suspension will not operate when

The vehicle height control may not be able to change modes when the vehicle runs

over a high curb or other rugged surfaces where the suspension is stretched.

CAUTION

The electronically modulated air suspension must be disabled when

The electronically modulated air suspension must be disabled in the following situa-

tions as vehicle height may change, resulting in accidental damage:

Any of the wheels is stuck in a ditch.

It is necessary to jack up the vehicle.

It is necessary to tow the vehicle with part of it lifted.

When connecting/disconnecting a trailer

For safety, stop the hybrid system if necessary.
