WARNING
●Do not use the panoramic view
monitor system in the following
cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emer- gency tires
• When the front door or the tail- gate is not closed completely
• On roads that are not flat or straight, such as curves or
slopes
• If the suspension has been modified or tires of a size other
than specified are installed
●In low temperatures, the screen
may darken or the image may
become faint. The image could
distort when the vehicle is mov-
ing, or you may become unable
to see the image on the screen.
Be sure to visually check all
around the vehicle both directly
and using the mirrors before
proceeding.
●If the tire sizes are changed, the
position of the guide lines dis-
played on the screen may
change.
●The camera uses a special lens.
The distances between objects
and pedestrians that appear in
the image displayed on the
screen will differ from the actual
distances. ( P.335)
●When an aftermarket part is
installed in the display area of
the screen.
NOTICE
●In panoramic view/moving
view/see-through view, the sys-
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.
●The panoramic view/moving
view/see-through view display
does not extend higher than the
installation pos ition and image
capture range o f each camera.
●There are blind spots around
the vehicle. Accordingly, there
are regions not displayed in
panoramic view.
●Three-dimensional objects dis-
played in wide fr ont view, rear
view or side view may not be
displayed in panoramic
view/moving view/see-through
view.

*: If equipped
The system can be used only on
2WD models. The system is
activated when driving at a

in a safe place. (There is no prob-
lem with continuing normal driving.)
The system will be automatically
restored after a short time.
AUTO LSD system*
The AUTO LSD system aids
traction by using the trac-
tion control system to con-
trol hybrid system
performance and braking
when one of the drive
wheels begins to spin. The
system should be used only
when one of the drive
wheels spinning occurs in a
ditch or rough surface.
System operation
WARNING
■To avoid an accident
●Do not use the AUTO LSD sys-
tem in conditions other than
when one of the drive wheels
spinning occurs in a ditch or
rough surface.
●Do not drive with the AUTO
LSD system continuously
turned on.
Failure to do so, a much greater
steering effort an d more careful
cornering control will be required.

WARNING
■The ABS does not operate
effectively when
●The limits of tire gripping perfor-
mance have been exceeded
(such as excessively worn tires
on a snow covered road).
●The vehicle hydroplanes while
driving at high speed on wet or
slick roads.
■Stopping distance when the
ABS is operating may exceed
that of normal conditions
The ABS is not designed to
shorten the vehicle’s stopping dis-
tance. Always maintain a safe dis-
tance from the vehicle in front of
you, especially in the following sit-
uations:
●When driving on d irt, gravel or
snow-covered roads
●When driving with tire chains
●When driving over bumps in the
road
●When driving over roads with
potholes or uneven surfaces
■TRAC/VSC may not operate
effectively when
Directional control and power may
not be achievable while driving on
slippery road surfaces, even if the
TRAC/VSC system is operating.
Drive the vehicle carefully in con-
ditions where stability and power
may be lost.
■Hill-start assist control does
not operate effectively when
●Do not overly rely on hill-start
assist control. Hill-start assist
control may not operate effec-
tively on steep inclines and
roads covered with ice.
●Unlike the parking brake, hill-
start assist control is not
intended to hold the vehicle sta-
tionary for an extended period
of time. Do not attempt to use
hill-start assist control to hold
the vehicle on an incline, as
doing so may lead to an acci-
dent.

Always drive carefully. Reckless
driving may cause an accident.
Exercise particula r care when the
indicator light flashes.
■When the TRAC/VSC/Trailer
Sway Control systems are

Be especially careful and drive at
a speed appropriate to the road
conditions. As these are the sys-
tems to help ensure vehicle stabil-
ity and driving force, do not turn
the TRAC/VSC/Trailer Sway Con-
trol systems off unless necessary.
Trailer Sway Control is part of the
VSC system and will not operate
if VSC is turned off or experiences
a malfunction.
