Driving
■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.
■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
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 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 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 “Traction Cont rol 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.200)
■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 all of the following four condi-
tions are me t, 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
●The engine switch is in ON
■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
●The engine switch is in ON
■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 depressed 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 the above sys-
tems are operating.
None of these ind icates 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 be generated from

Vehicle specifications
would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
■Traction AA, A, B, C
The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.
A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.
Sustained high temperature can
cause the material
of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.
