■System check display
After turning the power switch to ON mode, “SYSTEM CHECK” is displayed while
system operation is checked.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 12 mph [20 km/h])
●When the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)
■Setting display automatic cancelation
In the following situations, setting display in which the settings can be changed
through the “DISP” button will automatically be turned off.
●When a warning message appears while the setting display is displayed
●When the vehicle begins to move while the setting display is displayed
■Tire inflation pressure (if equipped)
●It may take a few minutes to display the tire inflation pressure after the power switch
is turned to 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. 8 3 3 )

■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

CAUTION
■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, sand, dirt,
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
NOTICE
■To prevent damage to or incorrect operation of the LKA system
●Do not modify the headlights or attach stickers to the surface of the lights.
●Do not modify the suspension or sun visor, or replace them with non-genuine
parts.
