■Tire inflation pressure (if equipped)
Outside temperature, average fuel
consumption after refueling or driv-
ing range can be selected and dis-
played.
If displayed on the drive monitor,
other trip information or warning
messages can be displayed simulta-
neously.
For display and selection proce-
dures, follow the “Setting up the dis-
plays”.
The information displayed on the drive
monitor will not be displayed on the
trip information screen.
Displays inflation pressure of each tire.
The inflation pressure of the spare tire will not be dis-
played.

■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 the 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. (Customizable features →P. 777)
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 driver’s shifting and the new gear number
appearing on the display. This lag could cause 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.

4-5. Using the driving support systems
■If there are lane markers on only one side of the vehicle
The lane keeping assist function will not operate. Also, the lane departure warning
will not operate for the side on which lane markers could not be recognized.
■Conditions in which the function may not operate correctly
In the following conditions, the LKA system functions may not operate, or it may not
be possible to ensure adequate performance. Also, the camera sensor may be
unable to recognize lane lines causing the lane departure warning function to oper-
ate incorrectly, or the lane keeping assist function may not operate properly. How-
ever, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing
or before a ticket checkpoint
●When driving on a sharp curve
●When lanes are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is
extremely short
●When the lane markers are yellow (These may be more difficult for the system to
recognize compared to white markers.)
●When the lane markers are broken, “Botts’ dots”, “Raised pavement marker” or
stones
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
●When driving on a particularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the
entrance to or exit from a tunnel
●When sunlight or the headlights of oncoming vehicles are shining directly into the
camera lens
●When driving on roads that are branching or merging
●When driving on a road surface that is wet due to rain, previous rainfall, standing
water, etc.
●When the vehicle experiences strong up-and-down motion such as when driving
on an extremely rough road or on a seam in the pavement
●When headlight brightness at nighttime is reduced due to dirt on the lenses, or
when the headlights are misaligned
●When driving with a strong crosswind

Driving
●When driving on winding roads or roads that are uneven
●When driving on rough or unpaved roads
■When changing the tires
Depending on the tires used, sufficient performance may not be maintainable.
■Warning messages for LKA
Warning messages are used to indicate a system malfunction or to inform the driver
of the need for caution while driving. (→P. 700, 708)
CAUTION
■Before using the LKA system
Do not rely solely on the LKA system. The LKA system does not drive the vehicle
automatically, nor does it reduce the amount of care you need to take. As such, the
driver must always assume full responsibility for understanding his/her surround-
ings, for operating the steering wheel to correct the driving line, and for driving
safely.
Inappropriate or negligent driving could lead to an accident.
■To avoid operating the LKA by mistake
Switch the LKA off using the “LKA” switch when not in use.
■Situations unsuitable for LKA
Do not use LKA in any of the following situations.
Otherwise, the system may not function correctly and could result in an accident.
●When driving with snow tires, tire chains, a spare tire, or similar equipment
●When the tires have been excessively worn, or when the tire inflation pressure is
low.
●When there are objects or structures along the roadside that might be misinter-
preted as lane markers (such as guardrails, curb, reflector posts, etc.)
●When driving on snowy roads
●When pavement lane markers are difficult to see due to rain, snow, fog, etc.
●When there are visible lines on the pavement from road repairs, or if the remains
of old lane markers are still visible on the road
●When driving on slippery roads, such as those covered with rain, ice or snow
●When driving in a lane other than the driving or passing lanes on a freeway or
highway
●When driving on a road with lane closures due to maintenance, or when driving
in a temporary lane
●When emergency towing

Driving
CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS, TRAC and VSC systems will not function correctly if different tires are
installed on the vehicle.
Contact your Lexus dealer for further information when replacing tires or wheels.
■Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect the
driving assist systems, and may cause a system to malfunction.
