■
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
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.
■Luggage
Carrying heavy luggage can lead to poor fuel consumption. Avoid car-
rying 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 driv-
ing short distances will cause 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
●Vehicles without a smart key system
Turn the engine switch off and ensure that all the doors and
windows are closed.
● Vehicles with a smart key system
Turn the “POWER” switch off and ensure that all the doors
and windows are closed.
● Confirm the type of fuel. ( P. 107)
■ Opening the fuel tank cap
Pull up the opener to open the
fuel filler door.
Turn the fuel tank cap slowly
to open.

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.
Hang the fuel tank cap on the
back of the fuel filler door.STEP3

Fuel types
Unleaded gasoline (Octane rating 87 [Research Octane Number 91] or
higher)
■ Use of ethanol blended gasoline in a gasoline engine
●Make sure that the ethanol blended gasoline to be used has a suitable
Research Octane Number as outlined in “Fuel types”.
●Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).DO NOT use gasoline
containing more than 10%
ethanol.
(15% ethanol)
(50% ethanol)
(85% ethanol)

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 door, touch an
unpainted metal surface to discharge any static 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 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 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.

150 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. 492)
■ For efficient use
●Shift the shift lever 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 lever to P 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 time
may discharge the hybrid battery. The vehicle cannot run if the hybrid
battery is discharged.

172 2-1. Driving procedures
■Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically
restart in the following situations. When EV drive mode is canceled, a buzzer
will sound and the EV drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
● Vehicle speed becomes high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about 1.3 miles (2 km) if driving
at a speed of about 25 mph (40 km/h) or less. (The distance that is possible
depends on the hybrid battery [traction battery] level and driving conditions.)
■ Fuel economy
PRIUS c is designed to achieve the best possible fuel economy during nor-
mal driving (using the gasoline engine and electric motor [traction motor]).
Driving in EV drive mode more than necessary may lower fuel economy.
■ Vehicle Proximity Notification System sound
Even when EV drive mode is turned on, the Vehicle Proximity Notification
System may produce a sound. ( P. 25)
CAUTION
■Caution while driving
When driving in EV drive mode no engine noise is made. As such, pedestri-
ans, people riding bicycles or other people and vehicles in the surrounding
area may not be aware of the vehicle starting off or approaching them even if
the Vehicle Proximity Notification System is active. Therefore, take extra
care while driving.
