rear or change the screen display and use when checking.
WARNING
●Depending on the circumstances of the vehicle (number of passen gers,
amount of luggage, etc.), the position of the guide lines displ ayed on the
screen may change. Be sure to check visually around the vehicle before
proceeding.
●If the steering wheel is straight and the vehicle width guide l ines and the
estimated course lines are not in alignment, have the vehicle i nspected

Bed view
●The area covered by the camera
is limited. Objects which are close
to either corner of the bumper or
under the bumper cannot be seen
on the screen.
●The area displayed on the screen
may vary depending on vehicle
orientation or road conditions.
●The camera uses a special lens.
The distance in the image dis-
played on the screen will differ
from the actual distance.
●In the rear split view, there is a
blind spot due to the size (length
and height) of the trailer.
●In the hitch zoom view, if a backlit
license plate is equipped it may be
reflected in the screen.
●In the bed zoom view, the section
near the cabin is a blind spot.

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.

system detects a panic stop sit-
uation
■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintai n directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■AVS (Adaptive Variable
Suspension System) (if
equipped)
The damping force of the shock
absorbers are independently
controlled for the 4 wheels
according to factors including
the road surface conditions and
driving operation, contributing
toward enhancing smooth driv- ing comfort and superior stabil-
ity, and helping to maintain
vehicle posture.
In addition, the damping force
can be changed by selecting the
drive mode with the driving
mode select (
P.358), and driv-
ing comfort can be ensured
during off-road driving by setting
the front-wheel drive control
switch to “4L”.( P.361)
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■The Secondary Collision
Brake
When the SRS airbag sensor
detects a collision and the sys-
tem operates, the brakes and
brake lights are automatically
controlled to reduce the vehicle
speed and help reduce the pos-
sibility of further damage due to
a secondary collision.
■When the
TRAC/VSC/ABS/Trailer Sway
Control systems are operating
The slip indicator light will flash
while the TRAC/VSC/ABS/Trailer
Sway Control systems are operat-
ing.
