To help enhance driving safety and performance, the following systems operate automatically in response to various driving situations. Be aware, however, that these systems are supplementary and should not be relied upon too heavily when operating the vehicle.
ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slippery road surface
Brake assist
Generates an increased level of braking force after the brake pedal is depressed when the system detects a panic stop situation
VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces
TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning when starting the vehicle or accelerating on slippery roads
Hill-start assist control (if equipped)
Helps to prevent the vehicle from rolling backward when starting on an incline or slippery slope
EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn the steering wheel
Active Torque Control 4WD (AWD models only)
Automatically switches from front-wheel drive to AWD (All-Wheel Drive) according to driving conditions, helping to ensure reliable handling and stability. Examples of conditions where the system will switch to AWD are when cornering, going uphill, starting off or accelerating, and when the road surface is slippery due to snow or rain etc.
VDIM (Vehicle Dynamics Integrated Management) (if equipped)
Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start assist control, and EPS systems Helps to maintain vehicle stability when swerving on slippery road surfaces by controlling the brakes and engine output
PCS (Pre-Collision System) (if equipped)
When the TRAC/VSC systems are operating
The slip indicator light will flash while the TRAC/VSC systems are operating.
Disabling 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 Control OFF”/“TRAC OFF” will be shown on the multiinformation 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 hold
for more than 3
seconds while the vehicle is stopped.
The VSC OFF indicator light will come on and the “Traction Control OFF”/ “TRAC OFF” will be shown on the multi-information display.
Press again to turn the
systems back on.
When the message is displayed on the multi-information display showing
that TRAC has been disabled even if
has not been pressed
TRAC and hill-start assist control (if equipped) cannot be operated. Contact your Toyota dealer.
Sounds and vibrations caused by ABS, brake assist, TRAC, VSC and hill-start assist control (if equipped) systems
When the steering wheel is operated, a motor sound (whirring sound) 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 automatically re-enabled in the following situations:
Reduced effectiveness of the EPS system
The effectiveness of the 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.
Operating conditions of hill-start assist control (vehicles with a hill-start assist control system)
When the following four conditions are met, the hill-start assist control will operate:
Automatic system cancelation of hill-start assist control (vehicles with a hill-start assist control system)
The hill-start assist control will turn off in any of the following situations:
WARNING The ABS does not operate effectively when
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, especially in the following situations:
TRAC may not operate effectively when Directional control and power may not be achievable while driving on slippery road surfaces, even if the TRAC system is operating. Drive the vehicle carefully in conditions where stability and power may be lost. Hill-start assist control (vehicles with a hill-start assist control system)
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. When the TRAC/VSC systems are turned off Be especially careful and drive at a speed appropriate to the road conditions. 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, tread 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 different tires are installed 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.
