2003 TOYOTA PRIUS ignition

98
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
Either of the following conditions may
occur, but does not indicate the mal-
function:
The light may stay on for about 60
seconds after the ignition key is turned
to the “ON” position. It is normal if it
turns off after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if
it turns off after a few seconds.
(j) SRS Warning Light
This light will come on when the igni-
tion key is turned to the “ACC” or
“ON” position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side airbag sensors, front seat belt
pretensioner assemblies, warning light, in-
terconnecting wiring and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turn to the “ACC” or
“ON” position or remains on.

This light blinks when the fuel level in the
tank becomes very low. Fill up the tank
as soon as possible.
At the first blinking of the light, the mes-
sage appears on the display to remind the
driver to fill fuel.
Contact your Toyota dealer in the fol-
lowing cases:
All the segments blink.
The “E” mark and the segments indi-
cating remaining fuel blink.
(m) High Coolant Temperature Warning Light
The light operates to warn that the hybrid
system is almost over heating.
The light will come on when the ignition
key is turned to the “ON” position. After
a few seconds, the light will go off.
If it comes on while you are driving, stop
the vehicle and check your hybrid system.

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.)

“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.

52.Hybrid transaxle
Your hybrid transaxle has a shift lock sys-
tem to minimize the possibility of incorrect
operation. This means you can only shift
out of “P” position when the brake pedal
is depressed (with the ignition switch in
“ON” position and the lock release button
depressed).
(a) Selector lever
The shift position is also displayed on the
instrument cluster.
P:Parking, hybrid system starting and
key removal position
R: Reverse position
N: Neutral position
D: Normal driving position
B: Engine braking position
When the cruise control is being used
even if you shift the selector lever to “B”
position, engine braking will not be applied
because the cruise control is not can-
celled. For ways to decrease the vehicle
speed, see “Cruise control” on page 110.

pressed, shift while holding
the lock release button in.

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.

Operate the multiinformation display
with the ignition switch on.
When the ignition switch is turned to
“ON”, the initial “TOYOTA” screen appears
and the system begins operating.
After a few seconds, the previous mode
display will appear.
If the electrical power source has been
disconnected from the multiinformation
display, the display will be automatically
set to the initial mode.
CAUTION
Do not adjust the display while the
vehicle is moving. Be sure to adjust
the display only when the vehicle is
stopped.
Switch operation58.
This system operates mainly by the
switches on the screen. To protect the
screen, lightly touch switches on the
screen with your finger. When you touch
a switch on the screen or on the bezel,
a beep sounds.
If the system does not respond to a
touch of a switch, move your finger
away from the screen and then touch
it again.
You cannot operate dimmed switches.
Wipe off fingerprints on the surface of
the display using a glass cleaning
cloth.
