Driving■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock
when the brakes are applied
suddenly, or if the brakes are
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of
braking force after the brake
pedal is depressed when the
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or
turning on slippery road sur-
faces.
■Enhanced VSC (Enhanced
Vehicle Stability Control)
Provides cooperative control of
the ABS, TRAC, VSC and EPS.
Helps to maintain directional
stability when swerving on slip-
pery road surfaces by con-
trolling steering performance.
■Secondary Collision Brake
When the airbag sensor detects
a collision, the brakes and stop
lights are automatically con-
trolled to reduce the vehicle
speed and that helps reduce the
possibility of further damage
due to a secondary collision.
■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
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
Driving assist systems
To keep driving safety and
performance, the following
systems operate automati-
cally in response to various
driving situations. Be
aware, however, that these
systems are supplementary
and should not be relied
upon too heavily when oper-
ating the vehicle.

needed to turn the steering
wheel.
■When the TRAC/VSC systems
are operating
The slip indicator light will flash
while the TRAC/VSC systems are
operating.
■Disabling the TRAC system
If the vehicle gets stuck in mud, dirt
or snow, the TRAC system may
reduce power from the engine to the
wheels. Pressing to turn the
system off may mak e it easier for
you to rock the vehicle in order to
free it.
To turn the TRAC system off, quickly
press and release .
The “Traction Control Turned OFF”
will be shown on the multi-informa-
tion display.
Press again to turn the system
back on.
■Turning off both TRAC and VSC
systems
To turn the TRAC and VSC systems
off, press and h old for more than 3 seconds while the vehicle is
stopped.
The VSC OFF indicator light will
come on and the “Traction Control
Turned OFF” will be shown on the
multi-information display.
*
Press again to turn the system
back on.
*: PCS will also be
disabled (only
Pre-Collision warning is avail-
able). The PCS warning light will
come on and a message will be
displayed on the multi-information
display. ( P.185)
■When the message is dis-
played on the multi-information
display showing that TRAC has
been disabled even if has
not been pressed
TRAC is temporary deactivated. If
the information continues to show,
contact your Toyota dealer.
■Operating conditions of
hill-start assist control
When the following four conditions
are met, the hill-star t assist control
will operate:
●Vehicles with a continuously vari-
able transmission: The shift lever
is in a position o ther than P or N
(when starting off forward/back-
ward on an upward incline).
●Vehicles with a manual transmis-
sion: The shift lever is in a position
other than R when starting off for-
ward on an upward incline, or the
shift lever is in R when starting off
backward on an upward incline.
●The vehicle is stopped
●The accelerator pedal is not
depressed
●The parking brake is not engaged

Driving
■Automatic system cancelation
of hill-start as sist control
The hill-start assis t control will turn
off in any of the following situations:
●Vehicles with a continuously vari-
able transmission: The shift lever
is shifted to P or N.
●Vehicles with a manual transmis-
sion: The shift lever is shifted to R
when starting off forward on an
upward incline, or the shift lever is
shifted to other than R when start-
ing off backward on an upward
incline.
●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,
TRAC and hill-start assist con-
trol systems
●A sound may be heard from the
engine compartment when the
brake pedal is dep ressed repeat-
edly, when the engine is started or
just after the vehicle begins to
move. This sound does not indi-
cate that a malfunction 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.
• The brake pedal may pulsate
slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■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.
■EPS operation sound
When the steering wheel is oper-
ated, a motor sound (whirring
sound) may be heard. This does not
indicate a malfunction.
■Automatic reactivation of TRAC
and VSC systems
After turning th e TRAC and VSC
systems off, the systems will be
automatically re-enabled in the fol-
lowing situations:
●When the engine 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 o ff, 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 attempting to accel-
erate while turning
●The system detects that the vehi-
cle is drifting to the outer side
●The brake pedal is released
■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 and turn the engine
off. The EPS system should return
to normal within 10 minutes.
