Interior features
QChanging settings using the multi-information display
The air conditioning system settings can be changed on the screen
of the multi-information display. (P. 2 4 2 )
QFogging up of the windows
OThe windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
OIf you turn off, the windows may fog up more easily.
OThe windows may fog up if the recirculated air mode is used.
QWindshield fog detection function
When automatic mode is set, the humidity sensor (P. 534) detects fog on
the windshield and controls the air conditioning system to prevent fog.
QWhen driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.
QOutside/recirculated air mode
OSetting to the recirculated air mode temporarily is recommended in prevent-
ing dirty air from entering the vehicle interior and helping to cool the vehicle
when the outside air temperature is high.
OOutside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.
QFresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle.

other features that use electricity (for example, the seat heater, lights, wind-
shield wipers) are in operation or if the charge level of the 12-volt battery
becomes low.

Clean the air intake vents and filters periodically.
OIf continuing to drive the vehicle with “Maintenance Required for Traction
Battery Cooling Parts See Owner’s Manual” shown on the multi-information
display, the hybrid battery (traction battery) may overheat, leading to
decreasing in distance that can be driven using the electric motor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning

Maintenance and care
QThe initialization operation
OMake sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
OIf you have accidentally turned the power switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart
automatically when the power switch has been turned to ON mode for the
next time.
OIf you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.
QWarning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance
with the conditions under which it was initialized. For this reason, the system
may give a warning even if the tire pressure does not reach a low enough
level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
QWhen initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
OWhen operating the initialization of the system, the tire pressure warning
light does not flash 3 times and the setting message does not appear on the
multi-information display.
OAfter driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
QRegistering ID codes
The ID codes of the tire pressure warning valve and transmitters for two sets
of wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels of both normal tires and snow tires
are registered beforehand.
For information about changing ID codes, ask any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer.
