When driving
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 heavi ly 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)
Maintains drive power and prevents 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.
■Enhanced VSC (Enhanced vehicle stability control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.

142 2-4. Using other driving systems
When the TRAC/VSC systems are operatingThe slip indicator will flash while
the TRAC/VSC systems are
operating.
To disable TRAC and/or VSC systemsIf the vehicle gets stuck in fres h snow or mud, TRAC and VSC sys-
tems may reduce power from the engine to the wheels. You may
need to turn the system off to enable you to rock the vehicle in order
to free it.
■ Turning off TRAC
To turn the TRAC system off,
quickly press and release the
button.
The TRAC OFF indicator will
come on.
Press the button again to turn the
system back on.

2-4. Using other
driving systems

When driving
■Turning off TRAC and VSC systems
Press and hold the button for
more than 3 seconds while the
vehicle is stopped to turn off both
TRAC and VSC systems.
The TRAC OFF and VSC OFF
indicators will come on.
Press the button again to turn
both systems back on.
■When the TRAC OFF indicator com es on even if the VSC OFF switch
has not been pressed
TRAC system cannot be operated. Contact your Scion dealer.
■ 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 systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally reactivated in the following situations:
●When the engine switch is turned off
● 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.

144 2-4. Using other driving systems
■If the slip indicator comes on
There is a malfunction in the TRAC and VSC systems. Contact your Scion
dealer and have your Scion inspected.
■ 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 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.
CAUTION
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● 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 nor-
mal 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 fol-
lowing 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 uneven roads
■ When VSC is activated
The slip indicator flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator flashes.
