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 position information cannot be determined
due to unfavorable 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 the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
Customization
Setting of available languages can be changed. (Customizable features P.
857)
CAUTION
The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information dis-
play monitor may respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing 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.

Head-up display
The head-up display may seem dark and hard to see when viewed through
sunglasses, 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 the engine switch has been
turned off.
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 brightness may obstruct the driver’s view and lead to an accident, result-
ing 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 dis-
play indications.
Do not touch the inside of the head-up
display projector or thrust sharp edges
or the like into the projector.
Doing so could cause mechanical mal-

Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situ-
ations, the communication between the electronic key and the vehicle may be
affected, preventing the smart entry & start system, wireless remote control
and engine immobilizer system from operating properly. (Ways of coping:
P. 821)

Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electrical
noise
When carrying a portable radio, cellular phone, cordless phone or other
wireless communication device
When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
When other wireless keys (that emit radio waves) are being used nearby
When carrying the electronic key together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
