■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel
■E-Four (Electronic
On-Demand AWD system)
(AWD models)
Automatically controls the drive
system such as to front-wheel
drive or AWD (all wheel drive)
according to various running
conditions including normal driv-
ing, during cornering, on a
uphill, when starting off, during
acceleration, on a slippery roads
due to snow or rain, thus con-
tributing to stable operability and
driving stability.
■VDIM (Vehicle Dynamics
Integrated Management)
Provides integrated control of
the ABS, brake assist, TRAC,
VSC, hill-start assist control and
EPS systems
Helps to maintain vehicle stabil-
ity when swerving on slippery
road surfaces by controlling the
brakes, hybrid system output
and steering assist.
■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.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the hybrid sys-
tem to the wheels. Pressing the
switch to turn th e system off may
make it easier for you to rock the
vehicle in order to free it.
To turn the TRAC system off, quickly
press and release the switch.
The “Traction Cont rol Turned OFF”

are met, the hill-start assist control
will operate:
●The shift lever is in a position
other than P or N (when starting
off forward/backward on an
upward incline)
●The vehicle is stopped
●The accelerator pedal is not
depressed
●The parking brake is not engaged
■Automatic system cancelation
of hill-start assist control
The hill-start assist control will turn
off in any of the fo llowing situations:
●The shift lever is shifted to P or N
●The accelerator pedal is
depressed
●The parking brake is engaged
●2 seconds at maximum elapsed
after the brake pedal is released
■Sounds and vibrations caused
by the ABS, brake assist, VSC,
Trailer Sway Control, TRAC and
hill-start assist control systems
●A sound may be heard from the
engine compartment when the
brake pedal is depressed repeat-
edly, when the hybrid system is
started or just after the vehicle
begins to move. This sound does
not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions
may occur when the above sys-
tems are operating. None of these
indicates that a malfunction has
occurred.
• Vibrations may be felt through the
vehicle body and steering.

■Active Cornering Assist opera-
tion sounds and vibrations
When the Active Cornering Assist is
operated, operation sounds and
vibrations may b e generated from
the brake system, but this is not a
malfunction.
■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 of time. The steer-
ing wheel may feel heavy as a
result. Should this occur, refrain
from excessive steering input or
stop the vehicle and turn the hybrid
system off. The E PS system should
return to normal within 10 minutes.
■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 automatically
re-enabled in the following situa-
tions:
●When the power switch is turned
OFF
●If only the TRAC system is turned
off, the TRAC will turn on when
vehicle speed increases
If both the TRAC and VSC sys-
tems are turned off, automatic
re-enabling will not occur when
vehicle speed increases.
■Operating conditions of Active
Cornering Assist
The system operates when the fol-
lowing occurs.
●TRAC/VSC can operate
●The driver is at tempting to accel-
erate while turning

WARNING
■When the
TRAC/ABS/VSC/Trailer Sway
Control is activated
The slip indicator light flashes.
Always drive carefully. Reckless
driving may cause an accident.
Exercise particular 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 systems to help ensure
vehicle stability and driving
force, do not turn the
TRAC/VSC/Trailer Sway Con-
trol systems off unless neces-
sary.
●Trailer Sway Control is part of
the VSC system and will not
operate if VSC is turned off or
experiences a malfunction.
■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 red uce 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 effective. 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.196)
