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 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
Hybrid vehicles cannot be push
started.
If the instrument cluster is shown in
appropriate brightness when the hybrid
system is in the “IGON” mode—
The hybrid vehicle system is suspected to
be faulty. Contact your Toyota dealer. 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.
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.
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.
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—

(b) Jump starting

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 cau-
tiously 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.
4. Have everyone get out of the ve- hicle on the side away from traffic.

the following to reduce the possi-
bility of death or serious injury:
Follow jacking instructions.

ported by a jack. Personal inju-
ry may occu r.
 Do not start or run the hybrid

362
Make sure to set the jack prop-
erly in the jack point. Raising
the vehicle with jack improper-
ly positioned will damage the
vehicle or may allow the ve-
hicle 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
someone in the vehicle.
 When raising the vehicle, do
not place any objects on top
of or underneath the jack.
 Raise the vehicle only high
enough to remove and change
the tire.NOTICE
Do not continue driving with a
deflated tire. Driving even a
short distance can damage a
tire and wheel beyond repair.

Compact spare tire
The compact spare tire is designed
for temporary emergency use only.
The compact spare tire is identified
by the distinctive wording “TEM-
PORARY USE ONLY” molded into the
side wall of the tire.
The compact spare tire saves space
in your luggage compartment, and its
lighter weight helps to improve fuel
economy and permits easier installa-
tion in case of a flat tire.

3. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.

to loosen them. To get maximum le-
verage, 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 handle and pull
up on the handle. Be careful that the
wrench does not slip off the nut.

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 vehicl e, 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,

aside.
Roll the spare wheel into position and
align the holes in the wheel with the
bolts. Then lift up the wheel and get
at least the top bolt started through
its hole. Wiggle the tire and press it
back over the other bolts.
50p017c
Before putting on wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal− to−met-
al contact at the mounting surface can
cause wheel nuts to loosen and even-
tually cause a wheel to come off while
driving.

Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by hand. Press back on the
tire and see if you can tighten them
more.
CAUTION
Never use oil or grease on the
bolts or nuts. Doing so may lead
to overtightening the nuts and
damaging the bolts. The nuts
may loosen and the wheels may
fall off, which could cause a seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.

8. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclock-
wise to lower the vehicle.
Use only the wheel nut wrench to
tighten the nuts. Do not use other
tools or any additional leverage other
than your hands, such as a hammer,
pipe or your foot. Make sure the
wrench is securely engaged over the
nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.
