Turning on the high beam headlightsWith the headlights on, push
the lever away from you to
turn on the high beams.
Pull the lever toward you to the
center position to turn the high
beams off.
Pull the lever toward you and
release it to flash the high
beams once.
You can flash the high beams
with the headlights on or off.
■Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the engine is started and
the parking brake is released. Daytime running lights are not designed for
use at night.
● Compared to turning on the headlights, the daytime running light system
offers greater durability and consumes less electricity, so it can help
improve fuel economy.
■ Light reminder buzzer
A buzzer sounds when the driver’s door is opened with the key removed
from the engine switch while the lights are turned on.
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not run-
ning.

2-4. Using other driving systems
Scion_xB_OM_OM12G56U_(U)
Driving assist systems
When the VSC/TRAC systems 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.
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)
Helps to maintain drive power and prevent the drive wheels from spin-
ning 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

■Sounds and vibrati ons caused by the ABS, brake assist, VSC and
TRAC
● 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 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.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
●When the engine switch is turned to the “LOCK” position
● 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 re-enabling
will not occur when vehicle speed increases.
■ 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.

smoothly?
• The seat belts should not be dam- aged.
Seats • Do the seat controls operate
properly?
Steering wheel • Does the steering wheel rotate
smoothly?

Maintenance and care

CAUTION
■
When filling the reservoir
Take care as brake fluid can harm your hands and eyes and damage painted
surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately.
If you still experience discomfort, see a doctor.
NOTICE
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear out or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, there may be a serious proble\
m.
