Get IN CASE OF AN EMERGENCY -> If your vehicle will not start Guide for Toyota Prius 4 Door Second Generation (2004-2009)

If your vehicle will not start—

(a) Simple checks

(b) Jump starting

Before making these checks, make sure

you have followed the correct starting

procedure given in “How to start the

hybrid system” on page 348 and that you

have sufficient fuel. Also check whether

the other keys will start the hybrid

system. If they work, your key may be

broken. Have the key checked at your

Toyota dealer. If none of your keys work,

there may be a malfunction in the hybrid

vehicle immobilizer system. Call your

Toyota dealer. (See “Keys” on page 20.)

If the instrument cluster is shown in

appropriate brightness when the hybrid

system is in the “IG−ON” mode—

If the 12 volt battery is discharged, the

hybrid system can be started by jump

starting. Depending on the vehicle con-

dition, the engine may not start.

The hybrid vehicle system is suspected to

be faulty. Contact your Toyota dealer.

To avoid serious personal injury and

damage to your vehicle which might re-

sult from battery explosion, acid burns,

electrical burns, or damaged electronic

components, these instructions must be

followed precisely.

If the 12 volt battery is discharged, you

cannot access to the 12 volt battery in the

luggage compartment because the back

door cannot be opened. Use the exclusive

jump starting terminal in the engine

compartment. For details, see “JUMP

STARTING PROCEDURE” on page 357.

If the instrument cluster dims or the

instrument cluster display turns off

with the hybrid system on—

1. Check that the 12 volt battery terminals

are tight and clean.

2. If the 12 volt battery terminals are

O.K., the 12 volt battery is discharged.

You may try jump starting. See “(b)

Jump starting” for further instructions.

NOTICE

If the 12 volt battery is discharged

with the transaxle in “P”, your vehicle

cannot be moved unless the front

wheels are raised. This is because the

front wheels are locked by means of

the parking lock mechanism.

NOTICE

Hybrid vehicles cannot be push−

started.

If you are unsure about how to follow this

procedure, we strongly recommend that

you seek the help of a competent qualified

technician or towing service.

NOTICE

CAUTION

z The battery used for boosting must

be 12 V. Do not jump start unless

you are sure that the booster bat-

tery is correct.

ꢀ Booster battery contains sulfuric

acid which is poisonous and corro-

hybrid system may not start by

pushing the “POWER” switch. In

that case, push it once again. If the

“READY” light does not come on,

contact your Toyota dealer.

ꢀ If you should accidentally get acid

on yourself or in your eyes, remove

any contaminated clothing and flush

the affected area with water imme-

diately. Then get immediate medical

attention. If possible, continue to

apply water with a sponge or cloth

while en route to the medical office.

8. Connect the jumper cables in the order

a, b, c, d.

unnecessary lights and accessories.

a. Connect the clamp of the positive

(red) jumper cable to the exclusive

jump starting terminal.

b. Connect the clamp at the other end

of the positive (red) jumper cable to

the positive (+) terminal on the

booster battery.

When boosting, use the battery of

matching or higher quality. Any other

battery may be difficult to jump start

with. If jump starting is difficult, charge

the battery for several minutes.

6. If required, remove all the vent plugs

from the booster batteries. Lay a cloth

over the open vents on the batteries.

(This helps reduce the explosion haz-

ard, personal injuries and burns.)

at your Toyota dealer.

CAUTION

d. Connect the clamp at the other end

of the negative (black) jumper cable

to a solid, stationary, unpainted, me-

tallic point of the vehicle with the

discharged battery.

When making the connections, to

avoid serious injury, do not lean over

the battery or accidentally let the

jumper cables or clamps touch any-

thing except the correct battery termi-

nals or the ground.

If the first start attempt is not success-

ful...

Check that the clamp on the jumper

cables are tight. Recharge the discharged

battery with the jumper cables connected

for several minutes and restart your hybrid

system in the normal way.

The recommended connecting point is

shown in the following illustration:

9. Charge the discharged battery with the

jumper cables connected for approxi-

mately 5 minutes. At this time, run the

engine in the vehicle with the booster

battery at about 2000 rpm with the ac-

celerator pedal lightly depressed.

If the another attempt is not successful,

the battery may be depleted. Have it

checked at your Toyota dealer.
