Buzzer

Have your vehicle checked at your

Toyota dealer in the following cases:

D The brake system warning light re-

mains on together with the “ABS”

warning light.

This light comes on in the following cases

when the engine switch is in the “ON”

position.

D The light does not come on even if the

parking brake is applied when the en-

gine switch is in the “ON” position.

In this case, not only the anti−lock

brake system will fail but also the

vehicle will become extremely un-

stable during braking.

D When the parking brake is applied...

D The light does not come on even if the

engine switch is turned on with the

parking brake released.

This light comes on for a few seconds

when the engine switch is turned to the

“ON” position even after the parking brake

is released.

A warning light turning on briefly during

operation does not indicate a problem.

Any of the following conditions may oc-

cur, but do not indicate the malfunc-

tion:

D When the brake fluid level is low...

CAUTION

D The light may stay on for about 60

seconds after the engine switch is

turned to the “ON” position. It is nor-

mal if it turns off after a while.

CAUTION

If any of the following conditions oc-

curs, immediately stop your vehicle at

a safe place and contact your Toyota

dealer.

It is dangerous to continue driving

normally when the brake fluid level is

low.

D Depressing the brake pedal repeatedly

may turn on the warning light and

buzzer. It is normal if the light turns off

and the buzzer stops sounding after a

few seconds.

D The light does not turn off even

after the parking brake is released

while the engine is running.

D When the hydraulic brake booster

fails...

D The warning buzzer comes on to-

gether with the warning light.

If the hydraulic booster causes a problem

resulting in poor braking performance, the

warning light comes on and buzzer sounds

continuously.

D You may hear a small sound in the

engine compartment after the engine is

started or the brake pedal is depressed

In either case, this can indicate that

the brakes may not work properly

and your stopping distance will be-

come longer. Depress the brake

pedal firmly and bring the vehicle

to an immediate stop.

repeatedly. This is

a

pump pulsating

sound of the brake system, and it is

not a malfunction.

Then, if the seat belt is still unfastened,

the buzzer will sound in a different tone

for 20 seconds. Even if the vehicle speed

drops below 20 km/h (12 mph), the buzzer

will continue to sound. To stop the buzzer,

fasten the seat belt. If the buzzer still

sounds, make sure the driver’s seat belt

is fastened.

If the vehicle speed rises above 20 km/h

(12 mph) with the seat belt unfastened,

the buzzer will sound for about 10 sec-

onds. Then, if the seat belt is still unfas-

tened, the buzzer will sound in a different

tone for 20 seconds. Even if the vehicle

speed drops below 20 km/h (12 mph), the

tighten it.

The light may come on when the oil level

is extremely low. It is not designed to

indicate low oil level, and the oil level

must be checked using the level dipstick.

When the charging system warning

gine drive belt being broken may have

occurred. If the warning light comes

on, immediately stop the vehicle in a

safe place and contact your Toyota

dealer.

These cases are temporary malfunctions.

The malfunction indicator lamp will go off

after taking several driving trips.

(On−Board Diagnostics) system before

taking your vehicle for the inspection.

When you drive for about 7200 km (4500

miles) after the engine oil replacement,

this light illuminates for about 3 seconds

and then flashes for about 12 seconds

with the engine switch turned to the “ON”

position. If you continue driving without

the engine oil replacement, and if the driv-

ing range exceeds 8000 km (5000 miles),

the light will come on after the engine

switch is turned to the “ON” position. The

light will remain on thereafter.

For details, see “Emissions Inspection and

Maintenance (I/M) programs” on page 426

in Section 6.

Even if the abnormality of the electronic

throttle control system is corrected during

low speed driving, the system may not be

recovered until the engine is stopped and

the engine switch is turned to the “ACC”

or “LOCK” position.

(g) Low Fuel Level Warning Light

This light comes on when the fuel level

in the tank becomes nearly empty. Fill up

the tank as soon as possible.

On inclines or curves, due to the move-

ment of fuel in the tank, the low fuel level

warning light may come on earlier than

usual.

If the light is flashing, we recommend that

you replace the engine oil at an early

opportunity depending on the driving and

road condition. If the light comes on, re-

place it as soon as possible.

CAUTION

Be especially careful to prevent erro-

neous pedal operation.

155

07 12.25

You need to reset the light after the en-

gine oil replacement. Reset the light by

following the procedure below:

When the “ABS” warning light is on (and

the brake system warning light is off), the

following systems do not operate, but the

brake system still operates conventionally.

If either of the following conditions oc-

curs, this indicates a malfunction some-

where in the components monitored by

the warning light system. Contact your

Toyota dealer as soon as possible to

service the vehicle.

1. Turn the engine switch to the “ACC” or

“LOCK” position with the odometer

reading shown. (For details, see

“Odometer and two trip meters” on

page 148 in this Section.)

D Vehicle stability control system

CAUTION

D Downhill assist control system

(four−wheel drive models)

If the system fails to reset, the light will

remain flashing.

If the “ABS” warning light remains on

together with the brake system warn-

D Hill−start assist control system

(i) “ABS” Warning Light

When the “ABS” warning light is on (and

the brake system warning light is off), the

anti−lock brake system does not operate,

so that the wheels will lock up during a

sudden braking or braking on slippery

road surfaces.

The light comes on when the engine

switch is turned to the “ON” position. If

the anti−lock brake system and the brake

assist system work properly, the light

turns off after a few seconds. Thereafter,

if either of the systems malfunctions, the

light comes on again.

In this case, not only the anti−lock

brake system will fail but also the

vehicle will become extremely unsta-

ble during braking.
