The engine immobilizer system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The hybrid system will start only
when the electronic code in the chip
corresponds to the registered ID code
for the vehicle.The system is automatically set when the
key is removed from the ignition switch.
The indicator light will start flashing to
show the system is set.
In the following cases, contact your Toyota
dealer.
The indicator light stays on.
The indicator light does not start flash-
ing when the key is removed from the
ignition switch.
The indicator light flashes inconsistent-
ly.
Inserting the registered key in the ignition
switch automatically cancels the immobiliz-
er system, which enables the hybrid sys-
tem to start. The indicator light will go off. For your Toyota dealer to make you a
new key with built
−in transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the im-
mobilizer system or start the hybrid
system.
NOTICE
Do not modify, remove or disas-
semble the engine immobilizer sys-
tem. If any unauthorized changes or
modifications are made, proper opera-
tion of the system cannot be guaran-
teed.

3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its
clip—this prevents rattles. Then lower the
hood and make sure it locks into place.
If necessary, press down gently on the
front edge to lock it.
CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
To deter vehicle theft, the system is
designed to sound an alarm if any of
the side doors, back door or hood is
forcibly unlocked or the battery termi-
nal is disconnected and then recon-
nected when the system is set.
The alarm blows the horn intermittently
and flashes the headlights, tail lights and
turn signal lights, and turns on the interior
light.SETTING THE SYSTEM 1. Turn the ignition key to the “LOCK” position and remove it.
The indicator light will start flashing when
the key is removed from the ignition
switch. (See “Engine immobilizer system”
on page 25 in this Section for details.)
2. Have all passengers get out of the vehicle.
3. Close and lock all the side doors, back door and hood.
The indicator light will remain on when all
the side doors, back door and hood are
closed and locked.

Low fuel level
warning light
The gauge indicates the approximate
quantity of fuel remaining in the tank
when the ignition switch is on.
Nearly full—Needle at “F”
Nearly empty—Needle at “E”
It is a good idea to keep the tank over
1/4 full.
The needle moves when braking, acceler-
ating or making turns. This is caused by
the movement of the fuel in the tank.
If the fuel level approaches “E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible. On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.

Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 343 in
Section 4.
The power meter indicates the instanta-
neous output from the hybrid system in
approximate kilowatts.
While the hybrid system is regenerating
energy, the meter indicates negative.

In the following case, drive directly to
the nearest Toyota dealer.
The yellow warning light comes on
while driving.
Any of the following conditions may oc-
cur, but do not indicate the malfunc-
tion:
The red and yellow warning lights may
stay on for about 60 seconds after the
hybrid system is started. It is normal
if it turns off after a while.
Depressing the brake pedal repeatedly
may turn on the red warning light. It is
normal if the light turns off after a few
seconds.
You may hear a small sound in the
engine compartment after the hybrid
system is started or the brake p edal is
depressed repeatedly. This is a pump
pulsating sound of the brake system,
and it is not a malfunction.
You may hear a motor sound in the
engine compartment when the brake
pedal is depressed with the hybrid sys-
tem turned off.
The brake pedal stroke may be short
when you turn the key to the “START”
position with the brake pedal de-
pressed.
(b) Driver’s Seat Belt Reminder Light and Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON”,
the reminder light flashes and buzzer
sounds if the driver ’s seat belt is not fas-
tened. Unless the driver fastens the belt,
the light continues flashing and the buzzer
stops after about 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Reminder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON”,
the reminder light flashes if a passenger
sits in the front passenger seat and does
not fasten the seat belt.
If luggage or other load is placed on the
front passenger seat, depending on its
weight, the reminder light may flash. (d) Discharge Warning Light
This light warns that the auxiliary battery
is being discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The hybrid system will continue to oper-
ate, however, until the auxiliary battery is
discharged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
(e) Traction Battery Warning Light
This light comes on in the following
cases:
a. The traction battery voltage drops be- cause the transmission is left in the
“N” position.
If you put the transmission in the “P”
position and the light goes off, the system
is working properly. b. The traction battery is discharged.
If the traction battery is discharged and
the warning light comes on along with the
“READY” light, stop your vehicle in a safe
place and contact your Toyota dealer.
