NOTICE
■Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
● A filter is installed to the air intake vent. When the filter remains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 552.
■ 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 20 L (5.3 gal., 4.4 Imp.gal.) of fuel every 12 months (refuel
a total of at least 20 L [5.3 gal., 4.4 Imp.gal.] over a 12-month period), as
this may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.

■The meters and display illuminate when
The power switch is in ON mode.
■Adjusting the instrument cluster brightness (P. 192)
●The brightness levels that can be selected differ depending on whether the
tail lights are on and surrounding brightness levels, as shown in the table
below.
*: 22 levels of the brightness are displayed on the setting screen. However,
the brightness setting will be the brightest when other than 1st level (the
darkest) is selected. If other than 1st or 22nd level is selected, when the
tail lights are turned on in a dark place, the instrument cluster brightness
setting will be the selected level.
●If the taillights are illuminated in a dark environment, the instrument cluster
light dims. However, when the brightness of the instrument cluster is set to
minimum or maximum (1st or 22nd level of the instrument cluster bright-
ness), even if the taillights are illuminated, the instrument cluster light will
not dim.
■When disconnecting and reconnecting 12-volt battery terminals
The settings of the clock will be reset.
■Calendar settings
●Until the calendar settings are set, the check screen is displayed every time
the power switch is turned to ON mode.
●After the calendar information is set, it can be changed in the “Meter Custo-
mize” settings. (P. 245)

2664-1. Key information
PRIUS PHV_OM_OM47A89E_(EE)■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
●If the battery becomes low, an alarm will sound in the cabin and a message
will be displayed on the multi-information display when the hybrid system
stops.
●As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 616)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
You can replace the battery by yourself (P. 616). However, as there is a
danger that the electronic key may be damaged, it is recommended that
replacement is carried out by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
●To avoid serious deterioration, do not leave the electronic key within 1 m
(3 ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
