(a) Power Steering System WarningLight
This light comes on when the power
steering control system fails.
If the vehicle starts moving on the decline
before the ignition is turned on, turning
the ignition switch to “ON” will light up
this light. At this time, you may feel the
steering wheel heavy.
If this occurs, stop your vehicle complete-
ly, turn the ignition switch to “ACC” or
“LOCK” and start the hybrid system again.
CAUTION
If this light comes on, take your ve-
hicle to the Toyota dealer as soon as
possible. In this case, you may feel
the heavy steering wheel maneuver-
ing. Drive your vehicle while gripping
the steering wheel firmly.
(b) Hybrid Vehicle Battery Warning Light
This light comes on in the following
cases.
a. The hybrid vehicle battery voltage
drops with the running mode selector lever
left in “N” position.
The system works properly if you put the
running mode selector lever to “P” position
and the light goes off.
b. The fuel tank is completely empty. (See
“Fuel gauge” in this section for instruc-
tions.)
c. The hybrid vehicle battery is dis-
charged.
If this light comes on with the “READY”
light on in case of c., stop your vehicle
in a safe place and contact your Toyota
dealer. (c) Hybrid System Warning Light ()
This light comes on if there is a problem
in the electric motor, inverter unit, hybrid
vehicle battery, etc.
If this light is on, stop your vehicle in a
safe place immediately and contact your
Toyota dealer.
Even if the hybrid system warning light
comes on, you could increase the speed
a little temporarily by depressing the ac-
celerator pedal. Immediately pull up your
vehicle at a safe place and contact your
Toyota dealer.

“START”—The hybrid system is ready
to operate.
Turn the key to the “START” position and
hold the ignition switch at this position for
about a few seconds until the “READY”
light comes on and a beep sounds. (If the
ambient temperature is low such as during
winter conditions, it may take time until
the “READY” light is on.” The key will
return to the “ON” position when released.
Being different from ordinary vehicles, you
cannot start your vehicle with the running
mode selector lever in “N” position.
“ON”—The hybrid system starts to run
when the accelerator pedal is depressed
with the “READY” light and all accesso-
ries on.This is the normal driving position.
“ACC”—Accessories such as the radio
operate, but the hybrid system is off.
If you leave your key in the “ACC” posi-
tion for a while, put the running mode
selector lever in “P” position.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.
“LOCK”—The hybrid system is off and
the steering wheel is locked. The key
can be removed only at this position.
You must push in the key to turn it from
“ACC” to the “LOCK” position. The selec-
tor lever must be put in the “P” position
before pushing the key.
Vehicles with hybrid vehicle immobiliser
system–Once you remove the key, the hy-
brid vehicle immobiliser system is auto-
matically set. (See “Hybrid vehicle immobi-
liser system” on page 20 in Section 21.)
When starting the hybrid system, the key
may seem stuck at the “LOCK” position.
To free it, first be sure the key is pushed
all the way in, and then rock the steering
wheel slightly while turning the key gently.
NOTICE
Do not leave the key in the “ACC” or
“ON” position for a long time when
the hybrid system is off. The auxiliary
battery will discharge.

lock51.

108
If the driver ’s door is opened when the
the “READY” light is on and the the selec-
tor lever is at a position other than “P”
with the parking brake applied, you will
hear beeps to warn you to shift the selec-
tor lever to the “P” position.
CAUTION
While the vehicle is moving, never
attempt to move the running mode
selector lever into “P” position under
any circumstances. Serious mechani-
cal damage and loss of vehicle con-
trol may result.
NOTICE
Be sure to put the selector lever in
“P” position when parking. With the
selector lever in “N” position, the hy-
brid vehicle battery will not be
charged even the gasoline engine op-
erates. You cannot start your vehicle
if the selector lever is left in “N”
position for a long time because the
hybrid vehicle battery will discharge.
(f) Vehicle driving characteristics
Creeping
In order to hold the vehicle properly on an
incline and for better accelerator pedal
operation at starting, vehicle is designed
like an ordinary automatic transmission
vehicle which tends to move without de-
pressing the accelerator pedal with the
selector lever in a position other than “P”
or “N”.
With the selector lever 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 restricted area or dur-
ing 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 the electric ener-
gy to charge the hybrid vehicle battery.
At this time, the electric motor running
noise becomes larger.The operation is the same as an ordinary
gasoline powered vehicle.
You may experience the following condi-
tions while braking. As they do not indi-
cate the malfunction, perform braking as
usual:
When you turn the ignition switch to
“ON” with the brake pedal depressed,
you may feel a little push from the
brake pedal.
When you turn the ignition switch to
“ACC” or “LOCK” from “ON”, the brake
pedal may move a little.

109
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.
When the hybrid vehicle battery tempera-
ture is low or high, or the hybrid vehicle
battery capacity is decreased with the run-
ning mode selector lever at “R” during
driving, the output control warning light is
on and the output power may be limited.
If the output control warning light is on,
drive your vehicle without hard accelera-
tion. The output power will be limited par-
ticularly when backing up.
(g) If you cannot shift lever out of “P”position
If you cannot shift the selector lever from
the “P” position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see “If
you cannot shift running mode selector
lever” on page 188 in Section 5.

When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Fully depress the parking brake
pedal. For better holding power, first de-
press the brake pedal and hold it while
setting the parking brake.
To release: Depress the parking brake
pedal while depressing the brake pedal.
To remind you that the parking brake is
set, the parking brake reminder light in
the instrument panel remains on until you
release the parking brake.
CAUTION
Driving with the parking brake en-
gaged can reduce braking power.
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.

54.Cruise control
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of hybrid
system performance, although a slight
speed change may occur when driving up
or down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow
–covered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then shift the selec-
tor lever to “B” position to use en-
gine braking to slow down.
25p006
TURNING ON THE SYSTEM
To operate the cruise control, push the
”CRUISE ON·OFF” switch. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another push on the switch will
turn the system completely off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the ”CRUISE ON·OFF”
switch off when not using the cruise
control.
25p007
SETTING AT A DESIRED SPEED
The transmission must be in ”D” or “B”
before you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the ”SET/COAST”
direction and release it. This sets the ve-
hicle at that speed.
If the speed is not satisfactory, tap the
lever up for a faster speed, or tap it down
for a slower speed. Each tap changes the
set speed by 1.6 km/h (1.0 mph). You can
now take your foot off the accelerator
pedal.

111
If you need acceleration—for example,
when passing—depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:a. Pulling the control lever in the ”CANCEL” direction and releasing it.
b. Depressing the brake pedal.
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity. RESETTING TO A FASTER SPEED
Push the lever up in the ”RES/ACC” direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will gradually
gain speed.
However, a faster way to reset is to ac-
celerate the vehicle and then push the
control lever down in the ”SET/COAST”
direction.
RESETTING TO A SLOWER SPEED
Push the lever down in the ”SET/COAST”
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speed
will gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
control lever down in the ”SET/COAST”
direction.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal, pushing the lever up in the
”RES/ACC” direction will restore the speed
set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the ”CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, press the ”CRUISE
ON·OFF” button to turn the system off and
then press it again to turn it on.
If any of the following conditions then oc-
curs, there is some trouble in the cruise
control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.
