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-

CAUTION
Trunk easy closer (vehicles with power trunk lid)
Power trunk lid (if equipped)
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
Check the safety of the surrounding area to make sure there are no obsta-
cles or anything that could cause any of your belongings to get caught.
If anyone is in the vicinity, make sure they are safe and let them know that
the trunk is about to open or close.
If the trunk closer switch is pressed while the trunk lid is opening during
automatic operation, the trunk lid stops opening. Take extra care when on
an incline, as the trunk lid may open or close suddenly.
On an incline, the trunk lid may fall after it opens automatically. Make
sure the trunk lid is fully open and secure before using the trunk.
In the following situations, the power trunk lid may detect an abnormality
and automatic operation may be stopped. In this case, the trunk lid has to
be operated manually. Take extra care in this situation, as the stopped
trunk lid may suddenly fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the battery voltage suddenly drops, such as when the engine
switch is turned to IGNITION ON mode or the engine is started during
automatic operation
Do not attach any accessories other than genuine Lexus parts to the trunk
lid. The power trunk lid may not operate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.
In the event that the trunk lid is left
slightly open, the trunk easy closer will
automatically close it to the fully closed
position. It takes several seconds before
the trunk easy closer begins to operate.
Be careful not to catch fingers or any-
thing else in the trunk lid, as this may
cause bone fractures or other serious
