Navigation system
Selecting “Clear” on the “Consumption” screen will reset the fuel consump-
tion and the regenerated energy for the past 30 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.
Multi-information display
If the “POWER” switch is turned OFF, average fuel consumption and regen-
erated energy data will be reset.
■ Resetting the monthly fuel consumption/eco savings record
Press and hold the “TRIP” button while the monthly fuel consumption/eco
savings record is displayed.
A confirmation message will be displayed.
Press and hold the “TRIP” button to reset the data.
Press the “DISP” button to cancel the reset operation. The screen will return
to the previous display if no buttons are pressed for approximately 10 sec-
onds.
■ Cruising range
Displays the estimated maximum distance that can be driven with the quan-
tity 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 dis-
played.
■ Odometer/trip meter/distance to empty
The odometer/trip meter/distance to empty will not be displayed while the
monthly fuel consumption record or the eco savings record is being dis-
played.

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 th e fuel economy. (P. 204)
■ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 225)
■ 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 reta ined 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 t he 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 lar ge amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving s hort distances will ca use the engine to
repeatedly warm up, which can lead to poor fuel consumption.

1-6. Refueling
Opening the fuel tank cap
Perform the following steps to open the fuel tank cap:
■Before refueling the vehicle
●Turn the “POWER” switch off and close all the doors and win-
dows.
● Confirm the type of fuel. ( P. 132)
■ Opening the fuel tank cap
Pull up the opener to open the
fuel filler door.
Turn the fuel tank cap slowly
to open.
Hang the fuel tank cap on the
back of the fuel filler door.

Closing the fuel tank capAfter refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
■Fuel types
Use unleaded gasoline. (Octane rating 87 [Research Octane Number 91] or
higher)
■ Gasoline price setting screen
After refueling more than approximately 1.3 gal. (5 L, 1.1 Imp.gal.) L and
turning the “POWER” switch to ON mode, the gasoline price setting screen
will be automatically displayed on the multi-information display. ( P. 231)

CAUTION
■
When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel filler door, touch an
unpainted metal surface to discharge any st atic electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap. In hot
weather, pressurized fuel may spray out of the filler neck and cause injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.
■ When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
●Securely insert the fuel nozzle into the fuel filler neck
● Stop filling the tank after the fuel nozzle automatically clicks off
● Do not top off the fuel tank
■ When replacing the fuel tank cap
Do not use anything but a genuine Toyota fuel tank cap designed for your
vehicle. Doing so may cause a fire or other incident which may result in
death or serious injury.

NOTICE
■Refueling
Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle’s painted surface.

182 2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 562)
■ For efficient use
●Shift the shift position to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
● Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
● Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
● Shift the shift position to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift position in the N position for an extended period of time
may discharge the hybrid battery (traction battery). The vehicle cannot
run if the hybrid battery (traction battery) is discharged.
