Owners Manual_USA_M0C052_enbe displayed, have your vehicle
inspected by your Toyota dealer as
soon as possible.
■When the indicator turns on
Indicates a malfunction in the air
suspension system.
Have the vehicle inspected by your
Toyota dealer immediately. ( P.87,
508)
WARNING
■The electronically modulated
air suspension must be
turned off in the following cir-
cumstances:
Otherwise, the automatic leveling
function may cause the vehicle’s
height to change, and you may
catch part of yo ur body in the
vehicle, resulting in an unex-
pected accident or injury:
●When driving through water
such as shallow streams (Put
the vehicle height in “HI” mode
and turn off the electronically
modulated air suspension. Drive
at 18 mph [30 km/h] or slower.)
●When jacking up the vehicle,
installing tire chains or tying the
vehicle with chains/wires for
transportation via flat bed truck
(Turn the system to the manual
mode and stop the hybrid sys-
tem.)
●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”
mode and turn the system to the
manual mode.)
■Selecting the correct height
mode
Observe the following precautions
to prevent accidents or injury.
Failure to do so may cause dam-
age to parts of the vehicle, as well
as dangerous handling character-
istics, which may lead to fatal or
injury 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 acci-
dent.
●Do not select “HI” mode when
you load cargo on the roof lug-
gage 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 acci-
dent.
NOTICE
■Be careful in any place where
overhead space is limited.
When changing to a higher mode
or after unloading, the vehicle
height will rise. This may cause
damage to the vehicle.
■Do not select “LO” mode
when driving on bumpy
roads.
If the underbody of the vehicle
touches a rugged road surface,
the vehicle ma y be damaged.

Trailer Backup Guide uses
the rear camera to detect
the trailer and a trailer hitch
light, which allows the
driver to use the system at
night time.
The system calculates the
trailer angle by image pro-
cessing from the rear cam-
era and calculates trailer
length and hitch length
during the trailer setup (cali-
bration) maneuver.
