(g) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, your vehicle is de-
signed like a typical automatic transmis-
sion vehicle which tends to move without
depressing the accelerator pedal with the
transaxle in a position other than “P” or
“N”.
With the transaxle in a position other than
“P” or “N”, depress the brake pedal firmly
even when stopped and apply the parking
brake as required.
When moving in a compact area or during
a traffic jam, it is an effective way to
control the speed using only the brake
pedal operation without depressing the ac-
celerator pedal.
Regenerative brake
When the accelerator pedal is released or
the brake pedal is depressed, the electric
motor acts as a generator and converts
kinetic energy to electric energy to provide
deceleration and recover electric energy to
charge the hybrid battery.
At this time, the electric motor running
noise may increase.The operation is the same as a typical
gasoline powered vehicle.
You may experience the following condi-
tion while braking. As they do not indicate
a malfunction, perform braking as usual:
In the “OFF” mode, pressing the
“POWER” switch once or twice will se-
lect “ACC” or “IG
−ON” only if the brake
pedal is not depressed. In this condi-
tion, the brake pedal may move a little.
Hybrid driving
This vehicle runs in combination with the
gasoline engine and electric motor.
If the “READY” light is on, you can start
your vehicle even with the gasoline engine
stopped. (h) If the system malfunctions
In the following conditions, there is some
problem in the system.
The indicator on the “P” position switch
flashes. However, this does not indi-
cate a malfunction unless a warning
message appears in the multi
−informa-
tion display.
All frames of shift position indicators in
the instrument cluster flash.
The parking system error message ap-
pears on the multi −information display.
The instrument cluster and multi −infor-
mation display does not come on when
the “IG −ON” mode is enabled.
In these cases, stop your vehicle in a
safe and level place, apply the parking
brake securely and contact your Toyota
dealer immediately.
(i) When the 12 volt battery is discon- nected
Before you disconnect the 12 volt battery,
confirm the shift position is “P” and apply
the parking brake completely.
After you reconnect the 12 volt battery,
shift the shift lever to “N” and confirm the
shift position is in “N” when the “IG −ON”
mode is enabled.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, brake assist system, hybrid system
control, etc. This system automatically
controls the brakes and hybrid system
to help prevent the vehicle from skid-
ding when cornering on a slippery road
surface or operating steering wheel
abruptly.
The vehicle stability control system is acti-
vated when the vehicle speed is more
than about 15 km/h (9 mph).CAUTION
Do not rely exclusively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid death or serious injury. Reck-
less driving will result in an unex-
pected accident. If the slip indicator
light flashes, sounding an alarm,
special care should be taken while
driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use tires other than
specified, or mixed types or size,
the vehicle stability control system
may not function correctly. When
replacing the tires or wheels, con-
tact your Toyota dealer. (See
“Checking and replacing tires” on
page 411.)
25p115a
Slip indicator light
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light blinks in the follow-
ing conditions also.
The vehicle tires are racing. Utmost
care is required when driving.
When the anti−lock brake system is
operating. See “Brake system” on page
327 for details.

The slip indicator light comes on when the
“IG−ON” mode is enabled and will go off
after the “READY” light comes on. If the
indicator light does not come on when the
hybrid system is turned on, contact your
Toyota dealer.
25p117
“VSC” warning light
This light warns that there is a problem
somewhere in the vehicle stability control
system.
The light will come on when the “IG −ON”
mode is enabled and will go off after the
“READY” light comes on.
If the light comes on while driving, the
system does not work. However, because
the conventional braking still operates, you
can drive your vehicle without damaging
it. Contact your Toyota dealer. In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the “IG
−ON” mode is enabled.
The warning light remains on after the
“READY” light comes on.
The warning light comes on while driv-
ing.

The tire pressure warning system warns
you that the tire inflation pressure is
low.
The tire pressure warning system is not
a substitute for checking normal tire infla-
tion pressure. Check the tire inflation
pressure with a tire pressure gauge regu-
larly.
CAUTION
The warning system may not activate
immediately if bursts or sudden air
leakage should occur.
The tire pressure warning light comes on
when the “POWER” switch is selected in
“IG−ON” mode and goes off after a few
seconds. This means the tire pressure
warning light is operating properly. If the
tire inflation pressure becomes low, the
light comes on again. In this case, adjust-
ing the tire inflation pressure will turn off
the light after a few minutes. If the light
comes on after blinking for 1 minute, the
tire pressure warning system is not work-
ing properly. Indicator

CAUTION
If the tire pressure warning light
comes on, be sure to observe the
following precautions. Failure to do
so could cause loss of vehicle control
and result in death or serious injury.
Stop your vehicle in a safe place as
soon as possible. Adjust the tire
inflation pressure immediately.
If the tire pressure warning light
comes on even after tire inflation
pressure adjustment, it is probable
that you have a flat tire. Check the
tires. If the tire is flat, change to
the spare tire and have the flat tire
repaired by the nearest Toyota deal-
er.
Tire pressure warning system

151
Avoid abrupt maneuvering and bra-
king. If the vehicle tires deteriorate,
you could lose control of the steer-
ing wheel or the brakes.
The tire pressure warning light may turn
on due to natural causes such as natural
air leaks or tire inflation pressure changes
caused by temperature. In this case, ad-
justing the tire inflation pressure will turn
off the light after a few minutes.
Pushing the tire pressure warning reset
switch should not turn off the tire pressure
warning light. Adjusting the tire inflation
pressure will turn off the light.
The compact spare tire is not equipped
with the tire pressure warning valve and
transmitter. If a tire goes flat, the warning
light will not turn off even though the flat
tire is replaced with the spare tire. Re-
place the spare tire with the repaired tire
and adjust the proper tire inflation pressur-
e. The tire pressure warning light will turn
off after a few minutes.
CAUTION
Each tire, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label (tire
and load information label). (If your
vehicle has tires of a different size
than the size indicated on the vehicle
placard or tire inflation pressure label
(tire and load information label), you
should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).

152
NOTICE
Do not use liquid sealants for a flat
tire as tire pressure warning valve
and transmitter will be damaged.
 When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or an authorized tire dealer. The
tire pressure warning valves and
transmitters will be affected by the
installation or removal of tires.
IF THE TIRE PRESSURE WARNING
LIGHT COMES ON AFTER BLINKING
FOR 1 MINUTE...
If the tire pressure warning light comes
on after blinking for 1 minute when the
“POWER” switch is selected in “IGON”
mode, the tire pressure warning system
is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure warn-
ing valves and transmitters is not regis-
tered on the tire pressure warning ECU.
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non −genuine Toyota wheels are used.
If tire chains are used.
If the tire inflation pressure is more
than 500 kPa (5.1 kgf/cm2 or bar, 73
psi) or higher.
If the tire pressure warning light continues
to come on after blinking for 1 minute
when the “POWER” switch is selected in
“IG −ON” mode, have the system checked
by your Toyota dealer.
Even if you use genuine wheels, the tire
pressure warning system may not work
properly with some types of tires.

REPLACING TIRES AND WHEELS
When replacing the tires and wheels, be
sure to install tire pressure warning valves
and transmitters. ID codes on the tire
pressure warning valves and transmitters
are registered on the tire pressure warning
ECU. When replacing a tire pressure
warning valve and transmitter, it is neces-
sary to register the ID code of tire pres-
sure warning valve and transmitter. Have
the ID code registered by your Toyota
dealer.
If the ID code is not registered, the sys-
tem will not work properly. After about 1
hour, the tire pressure warning light
comes on after blinking for 1 minute to
indicate a system malfunction.
NOTICE
When the tires or tire pressure warn-
ing valves and transmitters must be
replaced, have them replaced by your
Toyota dealer. The tire pressure warn-
ing valves and transmitters will be
affected by the installation or removal
of tires.
Tire pressure warning reset switch
25p122
When initializing the system, the present
tire inflation pressure is stored as stan-
dard. The tire pressure warning system
determines decreased air pressure by
comparing the present and the standard
tire inflation pressures. When you change
the set tire inflation pressure, it is neces-
sary to initialize the tire pressure warning
system.
When rotating the tires on vehicles dif-
fering with front and rear tire inflation
pressures.
When changing the tire size.

155
To initialize the system, perform the fol-
lowing:1. Park the vehicle in a safe place and the hybrid system is off.
2. Adjust the pressure of all the installed tires to the specified cold tire inflation
pressure level. (See “Tires” on page
434.)
3. Turn the “POWER” switch to “IG −ON”
mode.
4. Push and hold the tire pressure warn- ing reset switch until the tire pressure
warning light blinks slowly three times.
5. Wait for a few minutes with the “POW- ER” switch selected in “IG −ON” mode,
and then turn the hybrid system off.
If you push the tire pressure reset switch
while the vehicle is moving, initialization is
not performed.
If you push the tire pressure reset switch
accidentally and initialization is performed,
adjust the tire inflation pressure to the
specified level and initialize the system
again.
25p124
If the tire pressure warning light does not
blink slowly three times when you push
and hold the reset switch, initialization has
failed and the tire pressure warning sys-
tem may not work properly. In this case,
initialize the system again. If initialization
cannot be performed, have the system
checked at your Toyota dealer.
CAUTION
Do not push the reset switch without
first adjusting the tire inflation pres-
sure to the specified level. Otherwise,
the tire pressure warning light may
not come on even if the tire inflation
pressure is low, or it may come on
when the tire inflation pressure is ac-
tually normal.
