The electric power steering system, us-
ing an electric motor, assists the turn-
ing of the steering wheel.
In the following cases, you may feel the
steering becomes heavy. However, the
electric power steering system warning
light does not come on. (Because it is
not a malfunction.)
When maneuvering the steering fre-
quently or keeping the steering wheel
turned fully while the vehicle is stopped
or moving very slowlyThe power steering effect will be re-
duced to prevent the system from over-
heating. Avoid turning the steering
wheel, or stop the vehicle. When you
leave the vehicle in the “IG −ON” mode
for a while, the system will become
cool.
NOTICE
If you repeat the operation which will
turn on the overheating prevention
function, the electric power steering
system may be damaged.
When the 12 volt battery is discharged
Check the 12 volt battery’s condition.
If necessary, recharge or replace the
battery. For details, see “Checking 12
volt battery condition” on page 414.
When the steering wheel is operated
with the hybrid system not to be turned
on (with the “READY” light off)
The 12 volt battery capacity is de-
creased temporarily. The system re-
turns to normal some time after the
hybrid system is turned on.
If there is a problem somewhere in the
electric power steering system, the warn-
ing light comes on in the multi −information
display. For details, see “Multi −information
display” on page 132.
When you move the steering wheel, an
electrical motor noise may be heard. This
is power steering motor noise, and is not
a malfunction.30p003
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.

You may hear a motor sound in the en-
gine compartment when the brake pedal is
depressed with the hybrid system off.
When the hybrid system is started or
stopped, you may hear a sound coming
from the hybrid battery in the luggage
compartment. However, this does not indi-
cate any trouble.
If there is a problem somewhere in the
hybrid system, the hybrid system malfunc-
tion warning light will come on in place of
the “READY” light. If this happens, contact
your Toyota dealer.
CAUTION
Never start the hybrid system from
outside the vehicle, or an accident
may occur. Be sure to sit on the driv-
er seat, then start the system when
driving.
NOTICE
The hybrid system cannot be
started when the shift position is
“N”. Be sure to put it in “P” and
then start the system.
 If any warning light comes on (See
page 125 for details.) or the 12 volt
battery is disconnected, the 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.
 When you start the hybrid system
at a lowered outside temperature, it
may take longer before the blinking

Always slow down in gusty crosswinds.
This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp −edged objects and
other road hazards. Failure to do so
can lead to severe tire damage such
as a tire burst.
Drive slowly when passing over bumps
or travelling on a bumpy road. Other-
wise, the impact could cause severe
damage to the tires and/or wheels.
When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and put the hybrid
transaxle “P”. If necessary, block the
wheels.
Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.
Tips for driving in various
conditions

352
Check the condition of the 12 volt bat-
tery and cables.
Cold temperatures reduce the capacity of
any 12 volt battery, so it must be in top
shape to provide enough power for winter
starting. Section 8−3 tells you how to
visually inspect the 12 volt battery. Your
Toyota dealer will be pleased to check the
level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 401 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota deal-
er—they will be pleased to help.
Keep the door locks from freezing.
Squirt lock de −icer or glycerine into the
locks to keep them from freezing.
Use a washer fluid containing an anti
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer ’s directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, push the “P” position
switch and block the rear wheels. Do not
use the parking brake, for snow or water
accumulated in and around the parking
brake mechanism may freeze, making it
hard to release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During extreme
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.40p050b
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your ve-
hicle.
Dinghy towing

356
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—
(a) Simple checks
(b) Jump starting

357
CAUTION
Booster battery contains sulfuric
acid which is poisonous and corro-
sive. Wear protective safety glasses
when jump starting, and avoid spil-
ling 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 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.
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.
NOTICE
The battery used for boosting must
be 12 V. Do not jump start unless
you are sure that the booster bat-
tery is correct.
 After jump starting procedure, the
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.

Exclusive jump starting
terminal cover
4. Open the exclusive jump starting termi-nal cover.
5. If the booster battery is installed in another vehicle, make sure the ve-
hicles are not touching. Turn off all
unnecessary lights and accessories.
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.) 7. 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.
