The illustration is an example for explanation and may differ from the
actual item.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high volt-
age system (about 520 V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

■If a warning light comes on, a warning message is displayed, or the 12-
volt battery has been disconnected
The hybrid system may not start. In this case, try to start the system again. If
the “READY” indicator does not come on, contact your Toyota dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started,
refuel the vehicle with at least enough gasoline to make the low fuel level
warning light ( P. 443) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
1.3 gal. [5.0 L, 1.1 Imp. gal.] when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic waves as conventional gasoline powered vehicles or home
electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

1-3. Theft deterrent system
Vehicles without a smart key system
The indicator light flashes after
the key has been removed from
the engine switch to indicate that
the system is operating.
The indicator light stops flashing
after the registered key has been
inserted into the engine switch to
indicate that the system has been
canceled.
Vehicles with a smart key system
The indicator light flashes after the “POWER” switch has been turned
off to indicate that the system is operating.
The indicator light stops flashing after the “POWER” switch has been
turned to ACCESSORY or ON mode to indicate that the system has
been canceled.
■ System maintenance
The vehicle has a maintenance-free type immobilizer system.
■ Conditions affecting operation
Depending on the surrounding environment and conditions, the immobilizer
system may not operate properly. This may prevent the hybrid system from
starting. ( P. 140)
Immobilizer system
The vehicle’s keys have built-in transponder chips that prevent
the hybrid system from starting if a key has not been previously
registered in the vehicle’s on-board computer.
Never leave the keys inside the vehicle when you leave the vehi-
cle.
This system is designed to help prevent vehicle theft but does
not guarantee absolute security against all vehicle thefts.

*: These lights turn on when the engine switch is turned to the “ON” position(vehicles without a smart key system) or the “POWER” switch is turned to
ON mode (vehicles with a smart key system) to indicate that a system
check is being performed. They will turn off after the hybrid system is on, or
after a few seconds. There may be a malfunction in a system if the lights
do not come on, or turn off. Have the vehicle inspected by your Toyota
dealer.

■ The brightness of the instrument panel lights
When the tail lights are turned on, the brightness will be reduced slightly
unless the control dial is turned up fully.
■ Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.

Cruising range
Displays the estimated maximum distance that can be driven
with the quantity of fuel remaining.
• This distance is computed based on your average fuel consumption.As a result, the actual distance that can be driven may differ from that
displayed.
• When only a small amount of fuel is added to the tank, the display may not be updated.
Vehicles without a smart key system:
when refueling, turn the engine switch to the “LOCK” position. If the
vehicle is refueled without turning the engine switch to the “LOCK”
position, the display may not be updated.
