Situations in which the vehicle height
control may not operate properly●
In the following situations, the vehicle
height may change slowly or may not
change to the correct height:
• When the vehicle comes into contact
with snow, ice, stone, etc.
• When the ambient temperature is low
• When the accumulator tank pressure is
low●
In the following situations, the vehicle
height may not change:
• If the hood or trunk is not fully closed
• If the brake pedal depressed and the
vehicle is stopped
• When the vehicle is on a significantly
uneven or undulating road

as due to passengers entering the vehicle or
cargo being loaded, or when the vehicle
height is changed using the vehicle height
adjustment switch, the air suspension com-
pressor and valves may operate and a sound may be heard. This does not indicate
a malfunction. ■
When the accumulator tank pressure is
low
When the accumulator tank pressure is low,
the air suspension compressor and valves
may operate repeatedly even though the
vehicle height is not being changed. This
does not indicate a malfunction.
