■Automatic leveling function
Regardless of the number of occupants or the luggage load, vehi cle height in
any mode is always adjusted to a fixed height by the automatic leveling func-
tion.
■ When “HI” mode is selected
The vehicle height will change to “N” mode when driving at the speeds of
18 mph (30 km/h).
■ When “LO” mode is selected
●The vehicle height will change to “N” mode when vehicle speed e xceeds
7 mph (12 km/h).
● This mode allows for easy access to the vehicle (getting in and out) and
easy loading and unloading.
■ The electronically modulated air suspension will not operate in the fol-
lowing cases:
● The underbody of the vehicle is touching the surface of the roa d.
● The area around the suspension is covered with ice.
The height control indicators will blink, turn off and then turn on continuously
to indicate that the electronically modulated air suspension is not operational.
To re-enable operation, turn off the engine and then restart it .
■ Even if you hear an operating noise
This does not indicate a problem in the electronically modulate d air suspen-
sion.
■ The electronically modulated air suspension failure warning
The warning message is displayed on the multi-information displ ay, and the
electronically modulated air suspension cannot be activated unt il the malfunc-
tion is corrected.
Stop the engine and start again. If the warning message turns off, the system
operating correctly. If the warning message continues to be displayed, have
your vehicle inspected by your Toyota dealer as soon as possibl e.

WARNING
■The electronically modulated air suspension must be turned off in the
following circumstances:
Otherwise, the automatic leveling function may cause the vehicle’s height to
change, and you may catch part of your body in the vehicle, resulting in an
unexpected accident:
● When driving through water such as shallow streams (Put the veh icle
height in “HI” mode and turn off the electronically modulated a ir suspen-
sion. Drive at 18 mph [30 km/h] or slower.)
● When jacking up the vehicle, installing tire chains or tying th e vehicle with
chains/wires for transportation via flat bed truck (Turn the system to the
manual mode and stop the engine.)
● When the vehicle must be towed (Put the vehicle height in “N” mode and
turn the system to the manual mode.)
● When the vehicle gets stuck (Turn the system to the manual mode .)
● When disconnecting a trailer (Put the vehicle height in “N” mod e and turn
the system to the manual mode.)
■ Selecting the correct height mode
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the vehicle, as w ell as dan-
gerous handling characteristics, which may lead to fatal or inj ury accidents.
● Before you lower the vehicle’s height, check under the vehicle to make
sure that no one is there.
● “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, resulting
in an accident.
● Do not select “HI” mode when you load 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, resulting
in an accident.
