Before making these checks, make sure
you have followed the correct starting
procedure given in ”How to start the
hybrid system” on page 162 in Section 4
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,
the hybrid vehicle immobiliser system is
possibly broken. Call your Toyota dealer.
(See ”Keys” on page 18 in Section 2−1.)
If the instrument cluster dims or the
instrument cluster display turns off
with the ignition switch on— 1. Check that the auxiliary battery termi- nals are tight and clean.
2. If the auxiliary battery terminals are O.K., the auxiliary battery is dis-
charged. You may try jump starting.
See “(b) Jump starting” for further in-
structions.
NOTICE
Hybrid vehicles cannot be push
started.
If the instrument cluster is shown in
appropriate brightness with the ignition
switch turned to on—
The hybrid vehicle system is suspected to
be faulty. Contact your Toyota dealer. If the auxiliary battery is discharged,
the hybrid system can be started by
jump starting. Depending on the the ve-
hicle condition, the engine may not
start.
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 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.
If your vehicle will not start—
(a) Simple checks
(b) Jump starting

169
CAUTION
Auxiliary battery and booster bat-
tery contain sulfuric acid which is
poisonous and corrosive. Wear pro-
tective safety glasses when jump
starting, and avoid spilling acid on
your skin, clothing, or vehicle.
If you should accidentally get acid
on yourself or in your eyes, remove
any contaminated clothing and flush
the affected area with water for im-
mediately. Then get immediate med-
ical attention. If possible, continue
to apply water with a sponge or
cloth while en route to the medical
office.
The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and do
not smoke or light a match while
jump starting.
Warning: Battery posts, terminals and
related accessories contain lead and
lead compounds, chemicals known to
the State of California to cause can-
cer and reproductive harm. Wash
hands after handling.
NOTICE
The battery used for boosting must
be 12 V. Do not jump start unless you
are sure that the booster battery is
correct.

5. Remove the positive terminal cover ofthe auxiliary battery.
6. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. Turn off all
unnecessary lights and accessories.
7. 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.) 8. If the engine in the vehicle with the
booster battery is not running, start it
and let it run for a few minutes. During
jump starting, run the engine at about
2000 rpm with the accelerator pedal
lightly depressed.

CAUTION
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.
10. Start the hybrid system. Make sure the “READY” light is on. If the hybrid ve-
hicle battery warning light comes on in
the multi −information display, the hybrid
vehicle battery is also discharged. Con-
tact your Toyota dealer.
11. Carefully disconnect the cables in the exact reverse order: the negative cable
and then the positive cable.
12. Carefully dispose of the battery cover cloths—they may now contain sulfuric
acid.
13. If removed, replace all the battery vent plugs.
If the cause of your auxiliary battery dis-
charging is not apparent (for example,
lights left on), you should have it checked.

172
If your hybrid system stalls while driving...1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Turn the ignition switch to ”OFF” posi- tion, and try starting the hybrid system
again.
If the hybrid system will not start, see “If
your vehicle will not start” on page 168.
CAUTION
If the hybrid system is not operating,
the power assist for the brakes and
steering will not work so steering and
braking will be much harder than usu-
al.
If your high coolant temperature warn-
ing light comes on, if you experience a
loss of power, or if you hear a loud
knocking or pinging noise, the hybrid
system has probably overheated. You
should follow this procedure... 1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in “P”
and apply the parking brake. Turn off
the air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the hybrid
system. Wait until the steam subsides
before opening the hood. If there is no
coolant boiling over or steam, leave the
hybrid system running and make sure
the electric cooling fan is operating. If
it is not, turn the ignition off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from theradiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the hybrid system is running,
keep hands and clothing away from
the moving fan and engine drive
belts.
4. If the coolant is leaking, stop the hy-brid system immediately. Call a Toyota
dealer for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the hy-
brid system is running. Fill it about half
full.
CAUTION
Do not attempt to remove the radiator
cap when the hybrid system and ra-
diator are hot. Serious injury could
result from scalding hot fluid and
steam blown out under pressure.
If your hybrid system stalls
while driving If your vehicle overheats

173
6. After the coolant temperature hascooled to normal, again check the cool-
ant level in the reservoir. If necessary,
bring it up to half full again. Serious
coolant loss indicates a leak in the
system. You s hould have it checked as
soon as possible at your Toyota dealer. 1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from
the traffic. Avoid stopping on the center
divider of a highway. Park on a level
spot with firm ground.
2. Stop the hybrid system and turn on your emergency flashers.
3. Firmly set the parking brake and put the transmission in “P”.
4. Have everyone get out of the vehicle on the side away from traffic.
5. Read the following instructions thor- oughly.
CAUTION
When jacking, be sure to observe the
following to reduce the possibility of
personal injury:
Follow jacking instructions.
Do not put any part of your body
under a vehicle supported by a
jack. Personal injury may occur.
Do not start or run the hybrid sys-
tem while your vehicle is supported
by the jack.
Stop the vehicle at a level firm
ground, firmly set the parking brake
and put the transmission in “P”.
Block the wheel diagonally opposite
to the one being changed if neces-
sary.
Make sure to set the jack properly
in the jack point. Raising the ve-
hicle with jack improperly posi-
tioned will damage the vehicle or
may allow the vehicle to fall off the
jack and cause personal injury.
Never get under the vehicle when
the vehicle is supported by the jack
alone.
Use the jack only for lifting your
vehicle during wheel changing.
Do not raise the vehicle with some-
one in the vehicle.
When raising the vehicle, do not
put an object on or under the jack.
Raise the vehicle only high enough
to remove and change the tire.
If you have a flat tire—

174
NOTICE
Do not continue driving with a de-
flated tire. Driving even a short dis-
tance can damage a tire and wheel
beyond repair.
50p007a
Compact spare tire
The compact spare tire is designed for
temporary emergency use only.
The compact spare tire is identified by the
distinctive wheel design and color and
special wording “TEMPORARY USE ONLY”
molded into the side wall of the tire.
The standard tire should be repaired and
replaced as soon as possible.
The compact spare tire saves space in
your luggage compartment, and its lighter
weight helps to improve fuel economy and
permits easier installation in case of a flat
tire.The compact spare tire can be used many
times, if necessary. It has tread life of up
to 4800 km (3000 miles) depending on
road conditions and your driving habits.
When tread wear indicators appear on the
tire, replace the tire.
See also the tire section on page 215 in
Section 8
−2 for details on the tread wear
indicators and other service information.
CAUTION
The compact spare tire was de-
signed especially for your Toyota.
Do not use it on any other vehicle.
Do not use more than one compact
spare tire at the same time.
Do not exceed 80 km/h (50 mph)
when driving with the compact
spare tire.
Avoid sudden acceleration, sudden
deceleration and sharp turns with
the compact spare tire.

175
NOTICE
Your ground clearance is reduced
when the compact spare tire is
installed so avoid driving over ob-
stacles and drive slowly on rough,
unpaved roads and speed bumps.
Also, do not attempt to go through an
automatic car wash as the vehicle
may get caught, resulting in damage.

2. Block the wheel diagonally opposite
the flat tire to keep the vehicle from
rolling when it is j acked up.
When chocking the wheel, place a wheel
block from the front for the front wheels
or from the rear for the rear wheels.
50p013a
3. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
Turn the wheel nuts counterclockwise to
loosen them. To get maximum leverage, fit
the wrench to the nut so that the handle
is on the right side, as shown above.
Grab the wrench near the end of the han-
dle and pull up on the handle. Be careful
that the wrench does not slip off the nut.

Make sure the jack is positioned on a
level and solid place.
50p015b
5. After making sure no one is in the vehicle, raise it high enough so that
the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the jack touches the vehicle
and begins to lift, double −check that it is
properly positioned.
