suspension should be stopped temporarily for a minute
between selections. Operate it again.

D Before you lower the vehicle height with the height select
switch, check under the vehicle to make sure that nothing to
damage the vehicle or no one to be injured is there and the
underbody of the vehicle does not touch the ground.
D After unloading, the height of a vehicle equipped with the
active height control suspension becomes slightly higher
than the normal vehicle height. Take sufficient care where
the overhead height is restricted.
The vehicle height cannot be raised if the vehicle load exceeds the
following limits:
D Up to 4 occupants* plus about 300 kg (661 lb.) in the normal
mode
D Up to 4 occupants* plus about 170 kg (375 lb.) in the high mode
*About 68 kg (150 lb.) for a person
If the above load capacity is exceeded, the desired vehicle height
may not be obtained even if the height select switch is pushed. (If
the vehicle height cannot be raised in the normal mode and the height
control indicator indicates "LO", this is because the vehicle is loaded
too heavily. Under these conditions, drive your vehicle with due
care.)
If the vehicle height cannot be raised even after unloading, push the
height select switch on the "B" side and then on the "Y" side. If this
does not work, turn off the ignition once and then turn on. Operate
the select switch again.
