tem combines images taken
from the front, back, left and
right side cameras into a single
image. There are limits to the
range and content that can be
displayed. Familiarize yourself
with the characteristics of the
panoramic view monitor system
before using it.
●Image clarity may decline at the
four corners of t he panoramic
view/moving view/see-through
view. However, this is not a mal-
function, as these are the
regions along the border of
each camera image where the
images are combined.
●Depending on lighting condi-
tions near each of the cameras,
bright and dark patches may
appear on the panoramic
view/moving view/see-through
view.

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.)

■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.
