162 2-3. Operating the lights and wipers
■Daytime running light system
●To make your vehicle more visible to other drivers, the headlights turn on
automatically whenever the engine is started and the parking brake is
released.
● 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.
● Vehicles with daytime running light control sensor: The brightness of
headlights will automatically change depending on the darkness of the
surroundings. The other exterior lights and instrument panel lights auto-
matically turn on or off.
■ Daytime running light co ntrol sensor (if equipped)
■ Light reminder buzzer
Vehicles without smart key system
A buzzer sounds when the engine switch is turned OFF and the driver's door
is opened with the key removed from the engine switch while the lights are
turned on.
Vehicles with smart key system
A buzzer sounds when the “ENGINE START STOP” switch is turned OFF or
to ACCESSORY mode and the driver's door is opened while the lights are
turned on.
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the daytime running light sys-
tem to malfunction.

When driving
■When the “TRAC OFF” indicator light comes on even if the VSC OFF
switch has not been pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ Sounds and vibrations caused by 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 ABS is activated.
■ If the slip indicator light comes on
There is a malfunction in the TRAC and VSC systems. Contact your Toyota
dealer and have your Toyota 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
■ABS does not operate 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.
