■ SRS warning light

This warning light system monitors the airbag sensor assembly, front impact

sensors, side impact sensors (front door), side impact sensors (front), driver’s

seat position sensor, driver’s seat belt buckle switch, front passenger occu-

pant classification system, “AIR BAG ON” indicator light, “AIR BAG OFF” indi-

cator light, front passenger’s seat belt buckle switch, seat belt pretensioners,

airbags, interconnecting wiring and power sources. (P. 34)

■ Electric power steering system warning light (warning buzzer)

When the battery charge becomes insufficient or the voltage temporarily

drops, the electric power steering system warning light may come on and the

warning buzzer may sound.

■If the malfunction indicator lamp comes on while driving

First check the following:

● Is the fuel tank empty?

If it is, fill the fuel tank immediately.

● Is the fuel tank cap loose?

If it is, tighten it securely.

The malfunction indicator lamp will go off after several driving trips.

If the malfunction indicator lamp does not go off even after several trips,

contact your Toyota dealer as soon as possible.

■ Front passenger detection sensor, seat belt reminder and warning

buzzer

● If luggage is placed on the front passenger seat, the front passenger detec-

tion sensor may cause the warning light to flash and the warning buzzer to

sound even if a passenger is not sitting in the seat.

● If a cushion is placed on the seat, the sensor may not detect a passenger,

and the warning light may not operate properly.

■ Warning light operations for unfastened rear passenger seat belts

● When opening and closing the rear door, the warning light comes on for

approximately a certain period of time.

● When any of the rear seat belts are unfastened, the warning light comes on.

When the rear doors are opened and closed while the warning light is on,

the warning light will turn off after approximately a certain period of time.

7-2. Steps to take in an emergency

■When the tire pressure warning light comes on

Inspect the appearance of the tire to check that the tire is not punctured.

If the tire is punctured: P. 449

If the tire is not punctured:

Carry out the following procedure after the tire temperature has lowered

sufficiently.

● Check the tire inflation pressure and adjust to the appropriate level.

●If the warning light does not go out even after several minutes, check

that the tire inflation pressure is at the specified level and carry out ini-

tialization. (P. 378)

The warning light may come on again if the above operations are con-

ducted without first allowing the tire temperature to lower sufficiently.

■The tire pressure warning light may come on due to natural causes

The tire pressure warning light may come on due to natural causes such

as natural air leaks and tire inflation pressure changes caused by tem-

perature. In this case, adjusting the tire inflation pressure will turn off the

warning light (after a few minutes).

■When a tire is replaced with a spare tire

The compact spare tire is not equipped with a tire pressure warning valve

and transmitter. If a tire goes flat, the tire pressure warning light will not

turn off even though the flat tire has been replaced with the spare tire.

Replace the spare tire with the repaired tire and adjust the tire inflation

pressure. The tire pressure warning light will go off after a few minutes.

■Conditions that the tire pressure warning system may not function

properly

P. 381

■If the tire pressure warning light frequently comes on after blinking

for 1 minute

If the tire pressure warning light frequently comes on after blinking for

1 minute when the engine switch is turned to the “ON” position (vehicles

without smart key system) or IGNITION ON mode (vehicles with smart

key system), have it checked by your Toyota dealer.

■ Warning buzzer

In some cases, the buzzer may not be heard because of noisy place or an

audio sound.

7-2. Steps to take in an emergency

441

WARNING

■ If both the ABS and the brake system warning lights remain on

Stop your vehicle in a safe place immediately and contact your Toyota

dealer. The vehicle will become extremely unstable during braking, and the

ABS system may fail, which could cause an accident resulting in death or

serious injury.

■ When the electric power steering system warning light comes on

When the light comes on yellow, the assist to the power steering is

restricted. When the light comes on red, the assist to the power steering is

lost and handling operations of the steering wheel become extremely

heavy. When steering wheel operations are heavier than usual, grip the

steering wheel firmly and operate it using more force than usual.

■If the tire pressure warning light comes on

Be sure to observe the following precautions. Failure to do so could

cause a loss of vehicle control and result in death or serious injury.

● Stop your vehicle in a safe place as soon as possible. Adjust the tire

inflation pressure immediately.

●If the tire pressure warning light comes on even after tire inflation pres-

sure adjustment, it is probable that you have a flat tire. Check the tires.

If a tire is flat, change it with the spare tire and have the flat tire

repaired by the nearest Toyota dealer.

● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,

you could lose control of the steering wheel or the brakes.

■If a blowout or sudden air leakage should occur

The tire pressure warning system may not activate immediately.

442

7-2. Steps to take in an emergency

WARNING

■Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly

when cold and inflated to the inflation pressure recommended by the

vehicle manufacturer on the vehicle placard or tire inflation pressure

label (tire and load information label). (If your vehicle has tires of a dif-

ferent size than the size indicated on the vehicle placard or tire inflation

pressure label [tire and load information label], you should determine

the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire

pressure monitoring system (TPMS-tire pressure warning system) that

illuminates a low tire pressure telltale (tire pressure warning light) when

one or more of your tires is significantly under-inflated. Accordingly,

when the low tire pressure telltale (tire pressure warning light) illumi-

nates, you should stop and check your tires as soon as possible, and

inflate them to the proper pressure. Driving on a significantly under-

inflated tire causes the tire to overheat and can lead to tire failure.

Under-inflation also reduces fuel efficiency and tire tread life, and may

affect the vehicle’s handling and stopping ability.

Please note that the TPMS (tire pressure warning system) is not a sub-

stitute for proper tire maintenance, and it is the driver’s responsibility to

maintain correct tire pressure, even if under-inflation has not reached

the level to trigger illumination of the TPMS low tire pressure telltale (tire

pressure warning light).

Your vehicle has also been equipped with a TPMS (tire pressure warn-

ing system) malfunction indicator to indicate when the system is not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion indicator is combined with the low tire pressure telltale (tire pressure

warning light). When the system detects a malfunction, the telltale will

flash for approximately one minute and then remain continuously illumi-

nated. This sequence will continue upon subsequent vehicle start-ups

as long as the malfunction exists. When the malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.

TPMS (tire pressure warning system) malfunctions may occur for a vari-

ety of reasons, including the installation of replacement or alternate tires

or wheels on the vehicle that prevent the TPMS (tire pressure warning

system) from functioning properly. Always check the TPMS (tire pres-

sure warning system) malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the replacement or alter-

nate tires and wheels allow the TPMS (tire pressure warning system) to

continue to function properly.

Vehicles without a smart key system:

Maintain the engine speed of the second vehicle and turn the

engine switch to the “ON” position, then start the vehicle’s engine.

Vehicles with a smart key system:

Maintain the engine speed of the second vehicle and turn the

engine switch to IGNITION ON mode, then start the vehicle’s

engine.

Once the vehicle’s engine has started, remove the jumper cables in

the exact reverse order from which they were connected.

To install the engine cover, conduct the removal procedure in

reverse. After installing, check that the fixed pins are inserted

securely.

Once the engine starts, have the vehicle inspected at your Toyota

dealer as soon as possible.

■ Starting the engine when the battery is discharged

The engine cannot be started by push-starting.

■ To prevent battery discharge

● Turn off the headlights and the air conditioning system while the engine is

stopped.

● Turn off any unnecessary electrical components when the vehicle is running

at a low speed for an extended period, such as in heavy traffic.

■Charging the battery

The electricity stored in the battery will discharge gradually even when the

vehicle is not in use, due to natural discharge and the draining effects of cer-

tain electrical appliances. If the vehicle is left for a long time, the battery may

discharge, and the engine may be unable to start. (The battery recharges

automatically during driving.)

■Precautions when the battery is discharged (vehicles with a smart key

system)

● In some cases, it may not be possible to unlock the doors using the smart

entry & start system when the battery is discharged. Use the wireless

remote control or the mechanical key to lock or unlock the doors.

● The engine may not start on the first attempt after the battery has recharged

but will start normally after the second attempt. This is not a malfunction.

● The engine switch mode is memorized by the vehicle. When the battery is

reconnected, the system will return to the mode it was in before the battery

was discharged. Before disconnecting the battery, turn the engine switch off.

If you are unsure what mode the engine switch was in before the battery dis-

charged, be especially careful when reconnecting the battery.

■ When replacing the battery

● Use a battery that conforms to European regulations.

● Use a battery that the case size is same as the previous one, 20 hour rate

capacity (20HR) is equivalent or greater, and performance rating (CCA) is

equivalent or greater.

Check the label on top of the battery for the battery size and specifications

(ex. LN2, 60 Ah, 345 A).

• If the sizes differ, the battery cannot be properly secured.

• If the 20 hour rate capacity is low, even if the time period where the vehi-

cle is not used is a short time, the battery may discharge and the engine

may not be able to start.

● For details, consult your Toyota dealer.

WARNING

■ Avoiding battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flam-

mable gas that may be emitted from the battery:

● Make sure each jumper cable is connected to the correct terminal and that

it is not unintentionally in contact with any other than the intended terminal.

● Do not allow the other end of the jumper cable connected to the “+” termi-

nal to come into contact with any other parts or metal surfaces in the area,

such as brackets or unpainted metal.

● Do not allow the + and - clamps of the jumper cables to come into contact

with each other.

● Do not smoke, use matches, cigarette lighters or allow open flame near

the battery.

■ Battery precautions

The battery contains poisonous and corrosive acidic electrolyte, while

related parts contain lead and lead compounds. Observe the following pre-

cautions when handling the battery:

● When working with the battery, always wear safety glasses and take care

not to allow any battery fluids (acid) to come into contact with skin, clothing

or the vehicle body.

● Do not lean over the battery.

● In the event that battery fluid comes into contact with the skin or eyes,

immediately wash the affected area with water and seek medical attention.

Place a wet sponge or cloth over the affected area until medical attention

can be received.

● Always wash your hands after handling the battery support, terminals, and

other battery-related parts.

● Do not allow children near the battery.
