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.

The TRAC OFF indicator light will come on.
Push again to turn the system back
on.
- Turning off both TRAC and VSC system
To turn the TRAC and VSC systems off, press and hold
for more than 3 seconds while the vehicle
is stopped.
• The TRAC OFF indicator light and VSC OFF indicator light will come on.
• Press again to turn the systems
back on.
- When the “TRAC OFF” indicator light comes on even if the VSC OFF switch has not been pressed
TRAC and hill-start assist control cannot be operated. Contact your Toyota dealer.
- Automatic reactivation of TRAC and VSC
After turning the TRAC and VSC systems off, the systems will be automatically reactivated in the following situations:
• When the “ENGINE START STOP” switch is turned off (vehicles with smart key system)
• When the engine switch is turned to the “LOCK” position (vehicles without smart
key system)
• If only the TRAC system is turned off, the TRAC will turn on when vehicle speed
increases
If both the TRAC and VSC systems are turned off, automatic reactivation will not occur when vehicle speed increases.
- Sounds and vibrations caused by the ABS, brake assist, 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 indicate 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 after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
- EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be heard.
This does not indicate a malfunction.
- Reduced effectiveness of EPS system
The effectiveness of EPS system 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 EPS system should return to normal within 10 minutes.
CAUTION
- The ABS does not operate effectively when
• The limits of tire gripping performance have been exceeded.
• The vehicle hydroplanes while driving at high speed on the wet or slick road.
- Stopping distance when the ABS is operating may exceed that of normal conditions
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 situations.
• 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 roads with uneven roads
- TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
CAUTION
- When TRAC and VSC are off
Be especially careful and drive at a speed appropriate to the road conditions.
As there are systems to ensure vehicle stability and driving force, do not turn off TRAC and VSC unless necessary.
- When the VSC is activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the indicator light flashes.
- 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 specified tire pressure level.
The ABS and VSC will not function correctly if different tires are fitted 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.
- Active Torque Control 4WD system
• The AWD system of this vehicle is intended to ensure driving stability on normal roads. It is not designed for use in demanding situations such as rally driving.
• Take care when driving on slippery road surfaces.
