NOTICE
■Hybrid battery (traction battery) air intake vent
● 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 get water or foreign materials in the air intake vent 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 your Toyota dealer.
● 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 or replacing the filter, contact your Toy-
ota dealer.
When “Maintenance Required for Hybrid Battery Cooling Parts at Your
Dealer” is shown on the multi-information display, the filter may be

● 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.
