VSC systems
●A sound may be heard from the engine compartment when the brake
pedal is depressed repeatedly, when the engine is started or ju st 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 system s are
operating. None of these indicates that a malfunction has occur red.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.

■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring so und) may
be heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
● Vehicles without a smart key system: When the engine switch is turned to
“LOCK” position
● Vehicles with a smart key system: When the “ENGINE START STOP”
switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle

WARNING
■
TRAC may not operate effectively when
Directional control and power may not be achievable while drivi ng on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and powe r may be lost.
■ When the VSC and/or brake LSD function is activated
The slip indicator light flashes. Always drive carefully. Reckl ess driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC systems off unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if di fferent tires
are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfuncti on.

Hill-start assist control
Hill-start assist control helps to maintain braking force to assist
starting off forward while facing uphill or starting off backward while
facing downhill. As hill-start assist control is initially disabled,
enable the system to make it operable. The enabled/disabled set ting
will be maintained the next time the engine is started.
The hill-start assist control ON
indicator will be illuminated
when system is enabled and
flash while the system is oper-
ating.
■ Enabling hill-start assist control
Park your vehicle in a flat, safe location.
Make sure that the parking brake is securely engaged.
Stop the engine by turning the engine switch to the “LOCK”
position (vehicles without a smart key system) or turning
the “ENGINE START STOP” switch off (vehicles with a
smart key system).
Start the engine and check t hat the ABS warning light and
slip indicator are off.
Press and hold for
approximately 30 seconds.
Check that both the VSC off
indicator and “TRAC OFF” indi-
cator illuminate and then turn
off.

Notes for hill-start assist control
●A slight jolt may be felt when starting off backward with the s hift lever in R
and then moving forward.
● If the braking power of hill-start assist control is insufficient, depress the
brake pedal.

WARNING
■Hill-start assist control precautions
●Do not overly rely on hill-start assist control. Hill-start ass ist control may
not operate effectively on steep inclines and roads covered wit h ice.
● Unlike the parking brake, hill-start assist control is not inte nded to hold the
vehicle stationary 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 accident.
● Do not stop the engine while hill-start assist control is operating, as hill-
start assist control will stop operating, possibly leading to a n accident.
