CAUTION
■If a safety system warning light does not come on
Should a safety system light such as ABS and the SRS airbag warning light
not come on when you start the engine, this could mean that these systems
are not available to help protect you in an accident, which could result in
death or serious injury. Have the vehicle inspected by your Toyota dealer
immediately if this occurs.
■ Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. ( →P. 315)
*1: These lights turn on when the engine switch is turned to the ON
position to indicate that a system check is being performed. They
will turn off after the engine is started, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if
the lights do not turn off. Have the vehicle inspected by your Toyota
dealer.
*2: Vehicles with VSC OFF switch
*3: The indicator flashes to indicate that the system is operating.
*4: The indicator comes on to indicate a malfunction.

2-4. Using other driving systems
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System) (if equipped)
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 (if equipped)
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) (if equipped)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control) (if equipped)
Maintains drive power and prevent the front wheels from spinning when
starting the vehicle or accelerating on slippery roads.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.

162 2-4. Using other driving systems
■VSC OFF mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The TRAC OFF and VSC OFF
indicators will come on.
The system is in TRAC off and
VSC off mode.
■Sounds and vibrations caused by the ABS, TRAC, VSC and brake
assist system
●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 after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Automatic reactivation of TRAC and VSC
Turning the “ENGINE START STOP” or the engine switch OFF after turning
off the TRAC and VSC systems will automatically re-enable them.

2-4. Using other
driving systems
2
When driving
■Automatic TRAC reactivation
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.
■ If the slip indicator lights up
There is a malfunction in the TRAC and VSC systems. Contact your Toyota
dealer and have your Toyota inspected.
■ If the brake system overheats
TRAC will cease operation and a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
■ 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.
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 the wet or slick
road.
