When the VSC/TRAC are operating
If the vehicle is in danger of slip-
ping or if any of the drive wheels
spins, the slip indicator light
flashes to indicate that the VSC/
TRAC systems are operating.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
■Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surface by controlling steering performance.
■Hill-start assist control (if equipped)
(P. 191)
■ Downhill assist cont rol system (if equipped)
(P. 193)

AUTO LSD function is activated when the system is in TRAC off
mode.
■ Turning off TRAC

■Automatic reactivation of TRAC and VSC
Vehicles without smart key system
Turning the engine switch OFF after turning off the TRAC and VSC systems
will automatically re-enable them.
Vehicles with smart key system
Turning the “ENGINE START STOP” switch OFF after turning off the TRAC
and VSC systems will automatically re-enable them.
■ Automatic TRAC reactivation
2WD models
If only the TRAC system is turned off, the TRAC system will be reactivated
while vehicle speed is increased. 4WD models
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC and VSC
●A sound may be heard from the engine compartment 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 systems 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 after the vehicle comes to a stop.
• The brake pedal may pulsate slightly when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ When the AUTO LSD function operates continuously
The brake actuator may overheat. In that case, the system will stop the
AUTO LSD function, a buzzer will sound and the slip indicator will stay on
steady. Refrain from using the AUTO LSD function until the slip indicator
goes off. (There is no problem with continuing driving normally.)

When driving
■EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
■ Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the engine off. The sys-
tem should return to normal within 10 minutes.
■ If the slip indicator comes on
It may indicate a malfunction in the VSC, TRAC and AUTO LSD function.
Contact your Toyota dealer.
CAUTION
■The ABS does not opera te effectively when
● Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick road.
■ Stopping distance when the ABS is ope rating on the wet or slick roads
The ABS is not designed to shorten the vehicle's stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
● When driving on dirt, 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 roads
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

190 2-4. Using other driving systems
CAUTION
■When the VSC is activated
The slip indicator flashes and a warning buzzer sounds. Always drive care-
fully. Reckless driving may cause an accident. Exercise particular care when
the indicator light flashes and a buzzer sounds.
■ When TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are systems to ensure vehicle stability and driving force, do
not turn off TRAC and VSC unless necessary.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC systems will not function correctly if different tires are fit-
ted on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause the system to malfunction.

Hill-start assist control
■Hill-start assist control operating conditions
• The shift lever is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.
: If equipped

192 2-4. Using other driving systems
■Hill-start assist control buzzer
●When hill-start assist control is activated, the buzzer will sound once
when the shift lever is in a position other than R.
● In the following situations, hill-start assist control will be canceled and the
buzzer will sound twice when the shift lever is in a position other than R.
• No attempt is made to drive the vehicle within approximately 2 seconds
of releasing the brake pedal.
• The shift lever is moved to P.
• The parking brake is applied.
• The brake pedal is depressed again.
● When the shift lever is in R, the buzzer indicating the start and end of the
operation does not sound. Use the slip indicator status (flashing or off) to
confirm if hill-start assist control is operating.
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.
CAUTION
■Hill-start assist control
●Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on extremely st eep inclines or roads covered in ice.
● Unlike the parking brake, hill-start assist control is not intended 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 for an extended
period of time, as doing so may lead to an accident.
