■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.

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.

hill-start assist control systems
●A sound may be heard from the
hybrid system compartment when
the brake pedal is depressed
repeatedly, when the hybrid sys-
tem is started or just after the vehi-
cle begins to move. This sound
does not indicate that a malfunc-
tion has occurred in any of these
systems.
●Any of the following conditions
may occur when t he above sys-
tems are operating. None of these
indicates that a malfunction has
occurred.
• Vibrations may be felt through the
vehicle body and steering.
• A motor sound may be heard also after the vehicle comes to a stop.
■ECB operating sound
ECB operating sound may be heard
in the following cases, but it does
not indicate that a malfunction has
occurred.
●Operating sound heard from the
engine compartment when the
brake pedal is operated.
●Motor sound of the brake system
heard from the front part of the
vehicle when the driver’ door is
opened.
●Operating sound heard from the
engine compartment when one or
two minutes passed after the stop
of the hybrid system.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sou nd (whirring sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of
TRAC, Trailer Sway Control and
VSC systems
After turning the TRAC, Trailer
Sway Control and VSC systems off,
the systems will be a utomatically re-
enabled in the following situations:
●When the power switch is turned
off
●If only the TRAC sy stem is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned of f, automatic re-
enabling will not occur when vehi-
cle speed increases.
■Reduced effectiveness of the
EPS system
The effectiveness of the EPS sys-
tem is reduced to prevent the sys-
tem from overheating when there is
frequent steering input over an
extended period o f time. The steer-
ing wheel may f eel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle a nd turn the hybrid
system off. The EPS system should
return to normal within 10 minutes.
■Secondary Collision Brake
operating conditions
The system operates when the SRS
airbag sensor de tects a collision
while the vehicle is in motion. How-
ever, the system does not operate
when the components are dam-
aged.
■Secondary Collision Brake
automatic cancelation

■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.
■When the TRAC/VSC/Trailer
Sway Control is activated
The slip indicator light flashes.
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
turned off
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.

WARNING
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pat-
tern and total load capacity. In
addition, make sure that the tires
are inflated to the recommended
tire inflation pressure level.
The ABS, TRAC, Trailer Sway
Control and VSC systems will not
function correctly if different tires
are installed on the vehicle.
Contact your Toyota dealer for fur-
ther information when replacing
tires or wheels.
■Handling of tires and the sus-
pension
Using tires with any kind of prob-
lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Trailer Sway Control precau-
tion
The Trailer Sway Control system
is not able to reduce trailer sway
in all situations . Depending on
many factors such as the condi-
tions of the vehicle, trailer, road
surface and driving environment,
the Trailer Sway Control system
may not be effec tive. Refer to
your trailer owner’s manual for
information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precau-
tions.
Failing to do so may cause death
or serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try
to control trailer sway by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very
gradually to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and traile r should stabi-
lize. ( P.181)
■Secondary Collision Brake
Do not rely solely upon the Sec-
ondary Collision Brake. This sys-
tem is designed to help reduce
the possibility of further damage
due to a secondary collision, how-
ever, that effect changes accord-
ing to various conditions. Overly
relying on the system may result
in death or serious injury.
