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. Set the “POWER” switch at ACC or off, and try starting the hybrid system
again.
If the hybrid system will not start, see “If
your vehicle will not start” on page 313 in
this Section.
CAUTION
If the hybrid system is not operat-
ing, the power assist for the brakes
and steering will not work so steer-
ing and braking will be much hard-
er than usual.
If the hybrid system stalls while
driving, do not open the driver’s
door until the vehicle comes to a
complete stop. Opening the driver’s
door locks the steering wheel, re-
sulting in loss of steering control.
Any of the following may indicate that
the hybrid system has overheated:
The engine coolant temperature
gauge indicates overheating.
The message “WATER TEMP” or
“HYBRID SYSTEM OVER HEAT” ap-
pears on the multiinformation dis-
play.
A loss of power is experienced.
A loud knocking or pinging noise is
heard.
If the hybrid system overheats, follow
the procedures below:
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 turned on and make
sure the electric cooling fan is operat-
ing. If it is not, turn the hybrid system
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 on, keep
hands and clothing away from the
moving fan.
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 on. Fill it about half full.
For the coolant type, see “Coolant type
selection” on page 357 in Section 7 −2.

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.
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 and put the transmission in “P”.
4. Have everyone get out of the ve- hicle on the side away from traffic.
5. Read the following instructions thoroughly.CAUTION
When jacking, be sure to observe
the following to reduce the possi-
bility of death or serious injury:
Follow jacking instructions.
 Do not put any part of your
body under the vehicle sup-
ported by the jack. Otherwise,
personal injury may occur.
 Do not start the hybrid system
while your vehicle is supported
by the jack.
 Stop the vehicle on a level firm
ground, firmly set the parking
brake and put the transmission
in “P”. Block the wheel diago-
nally opposite to the one being
changed if necessary.

What about doityourself maintenance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented on page 346 in
Section 7.
If you are a skilled do−it−yourself mechan-
ic, the Toyota service manuals are recom-
mended. Please be aware that do −it−your-
self maintenance can affect your warranty
coverage. See “Owner ’s Warranty Informa-
tion Booklet” or “Owner ’s Manual Supple-
ment” for the details. Listed below are the general maintenance
items that should be performed as fre-
quently as specified. In addition to check-
ing the items listed, if you notice any
unusual noise, smell or vibration, you
should investigate the cause or take your
vehicle to your Toyota dealer or a quali-
fied service shop immediately. It is recom-
mended that any problem you notice be
brought to the attention of your dealer or
the qualified service shop for their advice.
CAUTION
Make these checks only with ade-
quate ventilation if the hybrid system
is operating.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See page 373 in Section 7
−3 for
additional information.
Coolant level
Make sure the coolant level is between
the full and low lines on the see −through
reservoir when the hybrid system is cold.
See page 357 in Section 7 −2 for addition-
al information.
Radiator, condenser and hoses
Check that the front of the radiator and
condenser are clean and not blocked with
leaves, dirt or insects. See page 358 in
Section 7 −2 for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See page 359 in Section 7 −2 for addition-
al information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See page 355 in Section
7 −2 for additional information.

Coolant reservoir for engine
Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “F” and “L” lines on the
reservoir. If the level is low, add the
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with the hybrid system temperature. How-
ever, if the level is on or below the “L”
line, add coolant. Bring the level up to the
“F” line.
Coolant reservoir for inverter, traction mo-
tor and motor generator
Look at the seethrough coolant reser-
voir when the hybrid system is cold.
The coolant level is satisfactory if it is
between the “FULL” and “LOW” lines
on the reservoir. If the level is low, add
coolant. (For the coolant type, see
“Coolant type selection” described be-
low.)
The coolant level in the reservoir will vary
with the hybrid system temperature. How-
ever, if the level is on or below the “LOW”
line, add coolant. Bring the level up to the
“FULL” line.If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, coolant filler cap, radiator
cap and drain cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the hy-
brid system is hot.
Coolant type selection
Use of improper coolants may damage
your cooling system.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non
−silicate, non −amine, non− nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
