Closing the fuel tank cap
After refueling, turn the fuel tank
cap until you hear a click. Once
the cap is released, it will turn
slightly in the opposite direction.
Turn the fuel tank cap slowly
to open.
Hang the fuel tank cap on the
back of the fuel filler door.STEP 3

■Fuel types
Use unleaded gasoline. (Octane rating 87 [Research Octane Number 91] or
higher)
■ If the fuel filler door opener is inoperable
If the fuel filler door opener switch cannot be operated, contact your Toyota
dealer. In the event that urgent refueling is required, follow the procedure
below.
Remove the cap slowly. Take care to prevent fuel from spilling
out, as fuel tank pressure may not have been adequately
reduced.
Fill the fuel tank carefully and sl owly. Use caution, as air being
discharged from inside the fuel tank may cause fuel to spray out
from the filler opening during refueling.
Open the fuel filler door using the lever in
the luggage compartment.STEP 1

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
● Finish refueling within 30 minutes. If more than 30 minutes passes, the
internal valve closes. In this condition, fuel may spill out if you continue to
refuel the vehicle. About 5 minutes after the valve is closed, a message
“CLOSE FUEL LID” will appear on the multi-information display. To refuel
the vehicle again, tighten fuel tank cap and close the fuel filler door, and
then press the fuel filler door opener switch again.
● 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.
■ Notice about fuel
For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal.(20 L, 4.4 Imp.gal.) of fuel every 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.

When driving
■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 613)
■ 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 charge.
● 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 charge.
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.

Shift position indicator
The position of the frame on the shift position indicator changes in
accordance with the current shift position.
When any shift position other than D or B is selected, the arrow toward
B and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position indica-
tor provided on the instrument cluster.
■ Shift position purpose
*: For good fuel economy and noise reduction, the D position should usu-
ally be used.

When driving
■
Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator pedal depression amount can be
generated more smoothly than it is in normal conditions and the
operation of the air conditioning system (heating/cooling) will be
minimized.
When the “ECO MODE” switch is pressed, the “ECO MODE” indicator
comes on.
Power mode
Use when high levels of response and feeling are desirable,
such as when driving in mountainous regions or when overtak-
ing.
When the power mode switch is pressed, the power mode indicator
comes on.

■
Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 247) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ For the shift positions
● When the “POWER” switch is off, the shift position cannot be changed.
● When the “POWER” switch is in ON mode (the hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
However, immediately after turning the “POWER” switch to ON mode,
the shift position may not change to N.
● When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
● When the “READY” indicator is flashing, the shift position cannot be
changed from P to another position even if the shift lever is operated.
Wait until the “READY” indicator changes from a flashing to a solid light,
and then operate the shift lever again.
● The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever in any of the following situations, the buzzer will sound and the
shifting operation will be disabled or the shift position will automatically
change to N. When this happens, select an appropriate shift position.
● Situations where the shifting operation will be disabled:
• When an attempt is made to change the shift position from P to another
position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B by moving the shift lever.
• When an attempt is made to change the shift position from P to another position by moving the shift lever while the charging cable is connected
to the vehicle.
