2104-3. Operating the lights and wipers
PRIUS c_U
■Daytime running light system
●The daytime running lights illuminate using the same lights as the headlights
and illuminate darker than the headlights.
● Type A: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically when all of the fol-
lowing conditions are met. (The daytime running lights are not designed for
use at night.)
• The hybrid system is started
• The parking brake is released
• The headlight switch is in the or position
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● Type B: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically when all of the fol-
lowing conditions are met. (The daytime running lights are not designed for
use at night.)
• The hybrid system is started
• The parking brake is released
• The headlight switch is in the or position
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
switch.
● Compared to turning on the headlights, the daytime running ligh t system
offers greater durability and consumes less electricity, so it can help improve
fuel economy.
■ Automatic light off system
Vehicles without a smart key system
● When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after the power switch is turned to the “ACC” or “LOCK” po sition and a
door is opened and closed. (Vehicles with a wireless remote con trol: The
lights turn off immediately if on the key is pressed after all the doors
are locked.)
● When only the tail lights are on: The tail lights turn off automatically if the
power switch is turned to the “ACC” or “LOCK” position and the driver’s door
is opened.
To turn the lights on again, turn the power switch to “ON” posi tion, or turn the
light switch off once and then back to or .
If any of the doors or trunk lid is kept open, the lights automatically turn off
after 20 minutes.

4067-1. Maintenance and care
PRIUS c_U
Start the hybrid system and check that “MAINTENANCE
REQUIRED FOR TRACTION BATTERY COOLING PARTS SEE
OWNER’S MANUAL” is no longer displayed on the multi-infor-
mation display.
It may take approximately 20 minu tes for the warning message to
disappear after the hybrid syste m is started. If the warning mes-
sage does not disappear even th ough the filter has been cleaned,
have the vehicle inspect ed by your Toyota dealer.
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle's interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. U se a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obt ained by keep-
ing the carpet as dry as possible.
■ Air intake vent maintenance
●If the vehicle is driven with the air intake vent clogged, the hybrid battery
(traction battery) may overheat and the fuel consumption may in crease.
● Depending on the conditions under which the vehicle is used, th e air intake
vent may need to be cleaned more regularly.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge . Also
check the belts periodically for excessive wear, fraying or cut s.
■ Cleaning the air intake vent filter
●Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter , contact your
Toyota dealer.
● If the vehicle is driven with the air intake vent filter clogged, the hybrid bat-
tery (traction battery) may overheat and the fuel consumption m ay increase.
● Depending on the conditions under which the vehicle is used, th e air intake
vent filter may need to be cleaned more regularly.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat isfy
the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

NOTICE
■Notice on fuel quality
● Do not use improper fuels. If improper fuels are used, the engi ne will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way ca talytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performan ce
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine k nocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
