(E) A warning buzzer sounds continu-ously from the instrument cluster
and from the vehicle when closing
the door after getting out of the ve-
hicle.
This indicates that the driver is attempting
to leave the vehicle carrying the key, ne-
glecting to follow the instructions for case
(D) above. The messages, “SHIFT TO P
RANGE” and “KEY IS NOT DETECTED”,
will also appear alternately on the multi −
information display and the master warn-
ing light will come on.
Get out of the vehicle only after setting
the transmission selector lever in the “P”
position, turning off the hybrid system by
pressing the “POWER” switch and
checking that the indicator light on the
“POWER” switch has gone off. (F) A warning buzzer sounds once from
the instrument cluster and three
times from the vehicle when a pas-
senger is getting out of the vehicle.
This indicates that the passenger is
attempting to leave the vehicle carrying
the key, without turning the hybrid system
off. The message “KEY IS NOT
DETECTED” will also appear on the
multi −information display and the master
warning light will come on.
When passengers get out of the vehicle,
care should be taken to leave the key
with the driver. If the driver begins driving
after a passenger gets out of the vehicle
carrying the key, a warning buzzer will
sound once more.
(G) A warning buzzer sounds from the vehicle for two seconds when lock-
ing the vehicle from the outside with
the door handle switch.
This indicates that the driver is attempting
to lock the door with the key still in the
vehicle.
Leave the vehicle only after making sure
that you are carrying the key. (H) A warning buzzer sounds once from
the instrument cluster when the
“POWER” switch is turned off.
This indicates that the key battery is low.
(This warning buzzer sounds only when
the hybrid system has been on or the
“POWER” switch has been set at ON for
20 minutes or more.) The message “LOW
KEY BATTERY” will also appear on the
multi −information display.
Change the key battery ahead of time in
order to ensure that the smart key system
works properly.
(I) A warning buzzer sounds repeatedly from the instrument cluster when
opening the driver ’s door with the
“POWER” switch turned off.
This indicates that the steering wheel is
not locked. Turn the engine off and then
open the door in order to lock the steering
wheel.

(J) The “POWER” switch flashes greenonce every second.
This indicates that the steering lock is
stuck. The message “S/T IS NOT
UNLOCKED” will also appear on the
multi −information display.
To free it, rotate the steering wheel slight-
ly while pressing the “POWER” switch.
(K) The “POWER” switch flashes amber once every 2 seconds.
When the message “CHECK S/T LOCK”
appears on the multi −information display—
This indicates a problem with the steering
lock function. Have your vehicle checked
at your Toyota dealer.
When no message appears on the multi −
information display—
This indicates a problem with the push
button start function. Have your vehicle
checked at your Toyota dealer. THEFT PREVENTION FUNCTION
When the hybrid system is turned off,
the engine immobilizer system is auto-
matically set. (See “Engine immobilizer
system” on page 24 in Section 1
−2.)
When the driver ’s door is opened after
turning off the hybrid system, the steer-
ing wheel will lock.
When the 12 volt battery is discharged,
the steering lock function may not op-
erate properly.
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 place the transmis-
sion in “P”. If necessary, block the
wheels.
Tips for driving in various
conditions

Make sure your coolant is properly pro-
tected against freezing.
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.)
See “Checking the coolant level” on page
357 in Section 7 −2 for details of coolant
type selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Check the condition of the 12 volt bat-
tery and cables.
Cold temperatures lower the performance
of the 12 volt battery, so it must be in top
shape to provide enough power for winter
starting. Section 7 −3 tells you how to
visually inspect the 12 volt battery. Your
Toyota dealer and most service stations
will be pleased to check the level of
charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 356 in Sec t i on 7 −2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealer—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, put the transmission into
“P” and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated 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 bad
winter driving, stop and check under the
fenders occasionally.
Winter driving tips

Improving fuel economy is easy—just take
it easy. It will help make your vehicle last
longer, too. Here are some specific tips
on how to save money on both fuel and
repairs:
Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See page
359 in Section 7 −2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the hybrid system,
causing greater fuel consumption.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid continuous speeding up and
slowing down. Stop−and− go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
When parking, be sure to put the
transmission into the “P” position. In
the “N” position, the engine operates
but electricity cannot be generated. The
hybrid battery will be discharged requir-
ing unnecessary engine power to re-
charge.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the brake
pedal. This causes premature wear,
overheating and poor fuel economy.
Maintain a moderate speed on high-
ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the hybrid system, which, in turn,
wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tunedup and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance.
(For scheduled maintenance informa-
tion, please refer to the “Scheduled
Maintenance Guide” or “Owner ’s Manu-
al Supplement”.)
CAUTION
Never turn off the hybrid system to
coast down hills. Your power steering
and brake booster do not function
when the hybrid system is off. In
addition, the emission control system
operates properly only when the hy-
brid system is operating.

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.
