■Operating conditions
After stopping the engine, the vehicle will remain lowered for a maximum of 60
seconds.
●Height selector switch (driver's side instrument panel)
• While the engine is running, any vehicle height mode can be selected.
• Luggage mode can only be selected when the shift lever is in P position.
●Height selector switch (luggage compartment)
• When the engine is running and the shift lever is in the P position, any vehicle
height other than “LO” mode can be selected.
• When the “ENGINE START STOP” switch is turned off, the vehicle height
can only be lowered (only the “∨” side of the switch can be operated).
This switch can only be operated when the back door is open.
●Height control off switch
When the vehicle is stopped with the “ENGINE START STOP” switch in IGNI-
TION ON mode, vehicle height control can be disabled/re-enabled.
■When changing vehicle height modes
Before operating the height selector switch to raise/lower the vehicle height,
ensure that there are no objects in the surrounding area that could damage the
vehicle.
■When “N” mode is selected
During high speed driving, the vehicle height will automatically change to that of
“LO” mode.
■When “HI” mode is selected
The vehicle height will change to that of “N” mode when vehicle speed reaches 50
km/h (31 mph) or when vehicle speed has exceeded 30 km/h (19 mph) for approx-
imately 10 seconds. Even if vehicle speed is reduced below 30 km/h (19 mph), the
vehicle height will not automatically return to “HI” mode.
■When “LO” mode is selected
The vehicle height will change to that of “N” mode when the engine is restarted.

■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 8 km/h (5 mph). Even if vehicle
speed is reduced below 8 km/h (5 mph), 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 turned off when
The electronically modulated air suspension must be turned off in the following situ-
ations as vehicle height may change due to the automatic leveling function, and, you
may catch part of your body in the vehicle and cause an accident, resulting in death
or serious injury.
●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 engine if necessary.
■“HI” mode
●“HI” mode should only be used when driving on rough roads, for example when
driving off-road. Because the vehicle's center of gravity will become higher when
in the mode, the vehicle may become unstable when turning abruptly and cause
an accident, resulting in death or serious injury.
●Do not select “HI” mode when loading cargo on the roof luggage carrier.
Because the vehicle's center of gravity will become higher when in the mode, the
vehicle may become unstable when turning abruptly, and cause an accident,
resulting in death or serious injury.
