CAUTION
D Before you lower the vehicle's height with the height
select switch, check under the vehicle to make sure
nothing that could damage the vehicle or no one who
could be injured is there and that the underbody of
the vehicle does not touch the ground.
D Do not select the "HI" mode when you load cargo on
the roof luggage carrier. Otherwise it may result in a
loss of control or vehicle rollover due to failure to
operate this vehicle correctly.
NOTICE
D If the vehicle height is changed frequently, the
compressor may overheat, causing the vehicle
height adjustment operation to stop.
D After unloading, vehicle height rises slightly. Take
sufficient care where overhead space is restricted.
D Do not select "LO" mode when on bumpy roads. If
the underbody of the vehicle touches the rugged
road surface, the vehicle may be damaged.
