Hybrid battery (traction battery) air vent
There is an air intake vent under
the right-hand front seat for the
purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the
hybrid battery (traction battery)
may overheat, leading to a
reduction in hybrid battery (trac-
tion battery) output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle will
not restart. To restart the hybrid system, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.

If a warning light comes on, a warning message is displayed or the 12-
volt battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
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. 476) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 7 L [1.8 gal.,
1.5 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
Electromagnetic waves
High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount
of electromagnetic 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.
Declaration of conformity
This model conforms to hydrogen emissions according to regulation
ECE100 (Battery electric vehicle safety).

CAUTION
If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. (P. 461)
Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.
Hybrid battery (traction battery)
Your vehicle contains a sealed lithium-ion battery. If disposed of improperly,
it is hazardous to the environment and there is a risk of severe burns and
electrical shock that may result in death or serious injury.
NOTICE
Hybrid battery (traction battery) air vent
Do not put foreign objects near the air vent. The hybrid battery (traction
battery) may overheat and be damaged.
Clean the air vent regularly to prevent the hybrid battery (traction battery)
from overheating.
Do not wet or allow foreign substances to enter the air vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.

Resetting the consumption data
“touch screen”
Selecting “Clear” on the “Trip information” screen will reset the fuel con-
sumption and the regenerated energy for the past 15 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
Using Eco drive mode
When using Eco drive mode, the torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving the fuel economy. (P. 226)
Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. (P. 243)
When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained when slow-
ing down.
Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic
reports before leaving and avoid delays as much as possible.
When encountering a delay, gently release the brake pedal to
allow the vehicle to move forward slightly while avoiding overuse
of the accelerator pedal. Doing so can help control excessive
gasoline consumption.

Highway driving
Control your speed and keep at a constant speed. Also, before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be retained when slowing down.
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed.
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce the burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause large amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
