To turn off the rear window defog-
ger before the 15 minutes has
elapsed, press the switch again.
This defogger is not designed for melting snow. If there is an accumulation of
snow on the rear window, remove it before using the defogger.
To turn on the mirror defoggers, switch the ignition ON and press the
rear window defogger switch (→P. 185).
The rear window defogger clears fog from the rear window.

Hazard Warning Flasher
The hazard warning lights warn
other drivers that your vehicle is a
traffic hazard and that they must
take extreme caution when near
it.
Depress the hazard warning
flasher and all the turn signals will
flash. The hazard warning indica-
tor lights in the combination meter
flash simultaneously.
●The turn signals do not work when the hazard warning lights are on.
● Check local regulations about the use of hazard warning lights while the
vehicle is being towed to verify that it is not in violation of the law.
The hazard warning lights should always be used when you stop
on or near a roadway in an emergency.

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 force than
normal to the brake pedal. But the distance required to stop will 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. Braking 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 when 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 failure. This could
cause loss of vehicle control and a serious accident. Avoid continuous
application of the brakes.
■ Dry off brakes that have become wet by driving slowly, releasing 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 distance or the
vehicle pulling to one side when braking could result in a serious accident.
Light braking will indicate whether the brakes have been affected.
■ 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.

■Setting the parking brake
Depress the brake pedal and
then firmly pull the parking
brake lever fully upwards with
sufficient force to hold the vehi-
cle in a stationary position.
■Releasing the parking brake
Depress the brake pedal and
pull the parking brake lever
upwards, then press the
release button. While holding
the button, lower the parking
brake lever all the way down to
the released position.
NOTICE
Do not drive with your foot held on the clutch pedal or brake pedal, or hold
the clutch pedal depressed halfway unnecessarily. Doing so could result in
the following:
●The clutch and brake parts will wear out more quickly.
● The brakes can overheat and adversely affect brake performance.

When Driving
For parking in snow, refer to Winter Driving (→P. 131) regarding parking
brake use.
The warning light turns on when the system has a malfunction.
Refer to Warning Lights on P. 157.
When the disc brake pads
become worn, the built-in wear
indicators contact the disc plates.
This causes a screeching noise to
warn that the pads should be
replaced.
When you hear this noise, consult your Toyota dealer as soon as pos-
sible.
NOTICE
Driving with the parking brake on will cause excessive wear of the brake
parts.

WARNING
■ Do not drive with worn disc pads
Driving with worn disc pads is dangerous. The brakes could fail and cause a
serious accident. As soon as you hear a screeching noise consult your
Toyota dealer.

3-5. Brake
During emergency braking situations when it is necessary to depress
the brake pedal with greater force, the brake assist system provides
braking assistance, thus enhancing braking performance.
When the brake pedal is depressed hard or depressed more quickly,
the brakes apply more firmly.
● When the brake pedal is depressed hard or depressed more quickly, the
pedal will feel softer but the brakes will apply more firmly. This is a normal
effect of the brake assist operation and does not indicate a malfunction.
● When the brake pedal is depressed hard or depressed more quickly, a
motor/pump operation noise may be heard. This is a normal effect of the
brake assist and does not indicate a malfunction.
● The brake assist equipment does not supersede the functionality of the
vehicle’s main braking system.

When Driving
Hill Launch Assist (HLA)∗
For vehicles with a manual transaxle, Hill Launch Assist (HLA) oper-
ates on a downward slope when the shift lever is in the reverse (R)
position, and on an upward slope when the shift lever is in a position
other than the reverse (R) position.
For vehicles with an automatic transaxle, Hill Launch Assist (HLA)
operates on a downward slope when the shift lever is in the reverse
(R) position, and on an upward slope when the shift lever is in a for-
ward gear.
● Hill Launch Assist (HLA) does not operate on a gentle slope. In addition, the
gradient of the slope on which the system will operate changes depending
on the vehicle’s load.
● Hill Launch Assist (HLA) does not operate if the parking brake is applied, the
vehicle has not stopped completely, or the clutch pedal is released.
● While Hill Launch Assist (HLA) is operating, the brake pedal may feel stiff
and vibrate, however, this does not indicate a malfunction.
● Hill Launch Assist (HLA) does not operate while the TCS/DSC indicator light
is illuminated.
Refer to Warning/Indicator Lights on P. 156.
● Hill Launch Assist (HLA) does not turn off even if the DSC OFF switch is
pressed to turn off the TCS/DSC.
∗: If equipped
Hill Launch Assist (HLA) is a function which assists the driver in
accelerating from a stop while on a slope. When the driver
releases the brake pedal and depresses the accelerator pedal
while on a slope, the function prevents the vehicle from rolling.
The braking force is maintained automatically after the brake
pedal is released on a steep grade.

WARNING
■Do not rely completely on Hill Launch Assist (HLA)
Hill Launch Assist (HLA) is an auxiliary device for accelerating from a stop
on a slope. The system only operates for about two seconds and therefore,
relying only on the system, when accelerating from a stop is dangerous
because the vehicle may move (roll) unexpectedly and cause an accident.
The vehicle could roll depending on the vehicle’s load or if it is towing some-
thing. In addition, for vehicles with a manual transaxle, the vehicle could sti\
ll
roll depending on how the clutch pedal or the accelerator pedal is operated.
Always confirm the safety around the vehicle before starting to drive the
vehicle.
