Refueling
Do not spill fuel during refueling. 
Doing so may damage the vehicle, such as causing the exhaust systems to
operate abnormally or damaging fuel s ystem components or the vehicle’s
painted surface.

PRIUS_U (OM47668U) U.S.A.
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 558)
■ For efficient use
● Put the shift lever into “D” when driving. 
In the “N” position, the gasoline engine operates but electricity cannot be
generated. 
The hybrid battery (traction battery) will be discharged requiring unnec-
essary engine power to recharge.
● Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the 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.
● Push the “P” position switch when parking.
In the “N” position, the hybrid battery (traction battery) does not recharge. 
Leaving the shift lever in the “N” position for an extended period of the
time may discharge the hybrid battery. The vehicle cannot run if the
hybrid battery is discharged.

■Possible driving distance when driving in EV-Drive Mode
Possible driving distance when driving in EV-Drive Mode is up to about 1/2
mile (1 km) if driven at a speed of about 25 mph (40 km/h) or less. (Possible
driving distance depends on the hybrid battery [traction battery] level and
driving conditions.)
■ Fuel economy
Your Toyota is designed to achieve the best possible fuel economy during
normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV-Drive Mode more than necessary may lower fuel
economy.
CAUTION
■While driving
When driving in EV-Drive Mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehicle
starting off or approaching them, so take extra care while driving.

Eco Driving Mode
Use Eco Driving Mode to help achieve low fuel consumption during
trips that involve frequent accelerating and braking.
Press the “ECO MODE” switch once more to cancel the Eco Driving
Mode.
Eco Driving Mode will not be canceled until the “ECO MODE” switch is
pressed, even if the “POWER” switch is turned to OFF.
Press the “PWR MODE” switch to change the driving mode to power
mode.
Power mode
Use when high levels of response and feeling are desirable, such as
when driving in mountainous r
egions or when overtaking.
Press the “PWR MODE” switch once more to cancel the power mode.
Turning the “POWER” switch to OFF once will cancel power mode.
Press the “ECO MODE” switch to change the driving mode to Eco Driv\
-
ing Mode.

Changing shift ranges to “P” positionPush the “P” position switch with
the brake pedal pressed down.
The “P” position icon is displayed
on the instrument cluster, and the
indicator on the “P” position
switch comes on.
You can only shift to other posi-
tions from “P” when the brake
pedal is depressed.
When parking, check that the “P”
position icon is displayed on the
instrument cluster, and release
the brake pedal gently after
applying the parking brake.
ITO21P107
■Using engine brake
To use the engine braking, shift the shift lever to “B” position.
● During high speed driving, you may feel that deceleration by engine brak-
ing is less than that of a typical vehicle.
● Do not continue normal driving with the transmission in “B” for a long
time.
This may cause decreased fuel economy. To prevent this, use “D” for
normal driving.
