3-4. Switches and Controls
When the lights are turned on, the
lights-on indicator light in the com-
bination meter turns on.
■Auto-light control (if equipped)
When the headlight switch is in the AUTO position and the ignition
is switched ON, the light sensor s enses the surrounding lightness
or darkness and automatically turns the headlights, other exter ior
lights and dashboard illumination on or off.
■ Headlights
●If the light switch is left on, the lights will automatically switch off approxi-
mately 30 seconds after switching the ignition off.
The time setting can be changed.
Refer to Customizable Features on P. 555.
● To prevent discharging the battery, do not leave the lights on while the
engine is off unless safety requires them.
■ Auto-light control
●The headlights, other exterior lights and dashboard illuminatio n may not turn
off immediately even if the surrounding area becomes well-lit because the
light sensor determines that it is night time if the surrounding area is contin-
uously dark for several minutes such as inside long tunnels, tr affic jams
inside tunnels, or in indoor parking lots.
In this case, the lights turn off if the light switch is turned to the OFF position.
● If the headlight switch and the windshield wiper switch are in AUTO, and the
wipers are operated at low or high speed by the auto wiper cont rol for sev-
eral seconds, bad weather conditions are determined and the hea dlights
may be turned on.
● The dashboard illumination can be adjusted by rotating the knob in the
instrument cluster.
Also, the day/night mode can be changed by rotating the knob un til a beep
sound is heard.
To adjust the brightness of the dashboard illumination:
Refer to Dashboard Illumination on P. 169.
● The sensitivity of the auto-light control may be changed.
Refer to Customizable Features on P. 555.

When Driving
NOTICE
●The light sensor also works as a rain sensor for the auto-wiper control.
Keep hands and scrapers clear of the windshield when the wiper lever is in
the AUTO position and the ignition is switched ON as fingers could be
pinched or the wipers and wiper blades could be damaged when th e wip-
ers activate automatically. If you are going to clean the windshield, be sure
the wipers are turned off completely when it is particularly te mpting to
leave the engine running. This is particularly important when clearing ice
and snow.
● Do not shade the light sensor by adher-
ing a sticker or a label on the wind-
shield. Otherwise the light sensor will
not operate correctly.

3-4. Switches and Controls
●Switching the auto-wiper lever from the OFF to the AUTO positio n while
driving activates the windshield wipers once, after which they operate
according to the rainfall amount.
● The auto-wiper control may not operate when the rain sensor tem perature is
about -10 °C (14 °F) or lower, or about 85 °C (185 °F) or higher.
● If the windshield is coated with water repellent, the rain sens or may not be
able to sense the amount of rainfall correctly and the auto-wip er control may
not operate properly.
● If dirt or foreign matter (such as ice or matter containing sal t water) adheres
to the windshield above the rain sensor, or if the windshield i s iced, it could
cause the wipers to move automatically. However, if the wipers cannot
remove this ice, dirt or foreign matter, the auto-wiper control will stop opera-
tion. In this case, set the wiper lever to the low speed positi on or high speed
position for manual operation, or remove the ice, dirt or forei gn matter by
hand to restore the auto-wiper operation.
● If the auto-wiper lever is left in the AUTO position, the wipers could operate
automatically from the effect of strong light sources, electrom agnetic waves,
or infrared light because the rain sensor uses an optical senso r. It is recom-
mended that the auto-wiper lever be switched to the OFF positio n other than
when driving the vehicle under rainy conditions.
● The auto-wiper control functions can be turned off. Refer to Cu stomizable
Features on P. 555
NOTICE
● When the wiper lever is in the AUTO position and the ignition is switched
ON, the wipers may move automatically in the following cases:
• If the windshield above the rain sensor is touched or wiped with a cloth.
• If the windshield is struck with a hand or other object from e ither outside
or inside the vehicle.
Keep hands and scrapers clear of the windshield when the wiper lever is
in the AUTO position and the ignition is switched ON as fingers could be
pinched or the wipers and wiper blades damaged when the wipers acti-
vate automatically. If you are going to clean the windshield, be sure the
wipers are turned off completely (when it is most likely that t he engine is
left running) this is particularly important when clearing ice and snow.
●Do not shade the rain sensor by adher-
ing a sticker or a label on the wind-
shield. Otherwise the rain sensor will
not operate correctly.

3-5. Brake
3
When Driving
Brake System
This vehicle has power-assisted brakes that adjust automatically
through normal use.
Should power-assist fail, you can stop by applying greater forc e than
normal to the brake pedal. But the distance required to stop wi ll be
greater than usual.
Foot Brake
WARNING
■ Do not coast with the engine stalled or turned off, find a safe place to
stop
Coasting with the engine stalled or turned off is dangerous. Br aking will
require more effort, and the brake’s power-assist could be depleted if you
pump the brake. This will cause longer stopping distances or even an acci-
dent.
■ Shift to a lower gear whe n going down steep hills
Driving with your foot continuously on the brake pedal or steadily applying
the brakes for long distances is dangerous. This causes overheated brakes,
resulting in longer stopping distances or even total brake fail ure. This could
cause loss of vehicle control and a serious accident. Avoid con tinuous
application of the brakes.
■ Dry off brakes that have become wet by driving slowly, releasin g the
accelerator pedal and lightly applying the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distan ce or the
vehicle pulling to one side when braking could result in a seri ous accident.
Light braking will indicate whether the brakes have been affect ed.
■ To apply the brakes correctly
● Wear shoes appropriate for driving in order to avoid your shoe contacting
the brake pedal when depressing the accelerator pedal.
● Always depress the brake pedal with
the right foot. Applying the brakes with
the unaccustomed left foot could slow
your reaction time to an emergency sit-
uation resulting in insufficient braking
operation.

3-6. ABS/TCS/DSC
3
When Driving
Antilock Brake System (ABS)
The driver will feel a slight vibration in the brake pedal and may hear a
chattering noise from the brake system. This is normal ABS syst em
operation. Continue to depress the brake pedal without pumping the
brakes.
The warning light turns on when the system has a malfunction.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
● Braking distances may be longer on loose surfaces (snow or grav el, for
example) which usually have a hard foundation. A vehicle with a normal
braking system may require less distance to stop under these co nditions
because the tires will build up a wedge of surface layer when t he wheels
skid.
● The sound of the ABS operating may be heard when starting the engine or
immediately after starting the vehicle, however, it does not in dicate a mal-
function.
The ABS control unit continuously monitors the speed of each
wheel. If one wheel is about to lock up, the ABS responds by
automatically releasing and reapplying that wheel’s brake.
WARNING
■ Do not rely on ABS as a su bstitute for safe driving
The ABS cannot compensate for unsafe and reckless driving, exce ssive
speed, tailgating (following another vehicle too closely), driv ing on ice and
snow, and hydroplaning (reduced tire friction and road contact because of
water on the road surface). You can still have an accident.

3-6. ABS/TCS/DSC
Traction Control System (TCS)
The warning light turns on when the system has a malfunction.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
To turn off the TCS, press the DSC OFF switch ( P. 219).
The Traction Control System (TCS) enhances traction and safety
by controlling engine torque and braking. W hen the TCS detects
driving wheel slippage, it lower s engine torque and operates th e
brakes to prevent loss of traction.
This means that on a slick surface , the engine adjusts automati-
cally to provide optimum power to the drive wheels, limiting
wheel spin and loss of traction.
WARNING
■ Do not rely on the Traction Cont rol System (TCS) as a substitute for
safe driving
The Traction Control System (TCS) cannot compensate for unsafe and
reckless driving, excessive speed, tailgating (following anothe r vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
■ Use snow tires or tire chains and drive at reduced speeds when roads
are covered with ice and/or snow
Driving without proper traction devices on snow and/or ice-cove red roads is
dangerous. The Traction Control System (TCS) alone cannot provide ade-
quate traction and you could still have an accident.

3
When Driving
This indicator light stays on for a
few seconds when the ignition is
switched ON. If the TCS or DSC is
operating, the indicator light
flashes.
If the light stays on, the TCS, DSC or the brake assist system may
have a malfunction and they may not operate correctly. Take you r
vehicle to your Toyota dealer.
● In addition to the indicator light flashing, a slight lugging s ound will come
from the engine. This indicates that the TCS/DSC is operating p roperly.
● On slippery surfaces, such as fresh snow, it will be impossible to achieve
high rpm when the TCS is on.

Dynamic Stability Control (DSC)
DSC operation is possible at speeds greater than 12 mph (20 km/h).
The warning light turns on when the system has a malfunction.
Refer to Contact Your Toyota Dealer and Have Vehicle Inspected on
P. 493.
The Dynamic Stability Control ( DSC) automatically controls
braking and engine torque in c onjunction with systems such as
ABS and TCS to help control si de slip when driving on slippery
surfaces, or during sudden or e vasive maneuvering, enhancing
vehicle safety.
Refer to ABS ( P. 215) and TCS ( P. 216).
WARNING
■Do not rely on the Dynamic Stabil ity Control as a substitute for safe
driving
The Dynamic Stability Control (DSC) cannot compensate for unsaf e and
reckless driving, excessive speed, tailgating (following anothe r vehicle too
closely), and hydroplaning (reduced tire friction and road contact because
of water on the road surface). You can still have an accident.
NOTICE
● The DSC may not operate correctly unless the following are obse rved:
• Use tires of the correct size specified for your Toyota on all 4 wheels.
• Use tires of the same manufacturer, brand and tread pattern on all 4 wheels.
• Do not mix worn tires.
● The DSC may not operate correctly when tire chains are used or a tempo-
rary spare tire is installed because the tire diameter changes.
