NOTICE
Do not select the low mode in the
bumpy roads. If the underbody of the
vehicle touches the rugged road sur-
face, the vehicle may be damaged.
Even if the engine is stopped while the
vehicle height is being lowered, the op-
eration continues for up to 12 seconds.

(e) Turning off the active height control
suspension
To turn off the active height control
suspension with the vehicle stopped,
push the height control switch. The
height control "OFF" indicator
comes on and the vehicle height is
fixed in the same mode as the height
control switch is pushed.
This status is memorized in the system
even after the engine is stopped.
If you push the switch again, the height
control "OFF" indicator light goes out and
the active height control suspension is
turned on.
CAUTION
If you drive through deep water over
about 500 mm (20 in.) in depth, put
the vehicle height in the HI (High)
mode with the active height select
switch and then turn off the active
height control suspension by pushing
the height control switch. Drive your
vehicle at 30 km/h (19 mph) or lower
speed.
NOTICE
z When jacking up or installing tire
chains, be sure to turn off the ac-
tive height control suspension and
stop the engine. Otherwise, the ve-
light hicle height may change because of
the automatic leveling function, re-
sulting in an accident.
z If your vehicle must be towed, put
the vehicle height in the normal
mode and turn off the active height
control suspension. Otherwise, the
vehicle height may change because
of the automatic leveling function,
resulting in an accident.
