For safety and security
■System maintenance
The vehicle has a maintenance-free type alarm system.
■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the fol-
lowing:
●Nobody is in the vehicle.
●The windows and moon roof are closed before the alarm is set.
●No valuables or other personal items are left in the vehicle.
■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
■Alarm-operated door lock
●When the alarm is operating, the doors ar e locked automatically to prevent intrud-
ers.
●Do not leave the key inside the vehicle when the alarm is operating, and make sure
the key is not inside the vehicle when recharging or replacing the battery.
●A person inside the vehicle opens a door,
the trunk or hood.
●The battery is recharged or replaced when
the vehicle is locked. ( P. 7 5 9 )
NOTICE
■To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper operation
of the system cannot be guaranteed.

■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the engine
switch is turned to IGNITION ON mode. It may also take a few minutes to display
the tire inflation pressure after inflation pressure has been adjusted.
●“---” may be displayed if the tire information cannot be determined due to unfavor-
able radio wave conditions.
●Tire inflation pressure changes with temperature. The displayed values may also be
different from the values measured using a tire pressure gauge.
■Liquid crystal display
Small spots or light spots may appear on th e display. This phenomenon is character-
istic of liquid crystal displays, and there is no problem continuing to use the display.
■Customization
Setting of available languages can be changed. (Custo mizable features: P. 7 9 3 )
CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the dr iver’s shifting and the new gear number
appearing on the display. This lag could ca use the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that the
vehicle is parked in a place with adequate ventilation. In a closed area such as a
garage, exhaust gases including harmful carbon monoxide (CO) may collect and
enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent battery discharge, ensure that the engine is running while setting up the
display features.

■Head-up display
●The head-up display may seem dark and hard to see when viewed through sun-
glasses, especially polarized sunglasses.
Adjust the brightness of the head-up display or remove your sunglasses.
●When the head-up display is turned off, it will remain off even if the engine switch is
turned to IGNITION ON mode after th e engine switch has been turned off.
●The startup image will be displayed on the head-up display after the engine switch
has been turned to IGNITION ON mode wh ile the head-up display switch is set to
on.
■When the battery is disconnected
The customize settings of the head-up display will be reset.
CAUTION
■Before using the head-up display
Check that the position and brightness of the head-up display image does not
interfere with safe driving. Incorrect adjustment of the image’s position or bright-
ness may obstruct the driver’s view and lead to an accident, resulting in death or
serious injury.
NOTICE
■To prevent damage to components
●Do not place any drinks near the head-up
display projector. If the projector gets wet,
electrical malfunctions may result.
●Do not place anything on or put stickers
onto the head-up display projector.
Doing so could interrupt head-up display
indications.
●Do not touch the inside of the head-up dis-
play projector or thrust sharp edges or the
like into the projector.
Doing so could cause mechanical malfunc-
tions.
