will be automatically turned on
(after approximately 1 second):
• Vehicle speed is above approxi-
mately 21 mph (34 km/h) or more.
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.

SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P.424).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front o f the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the win dshield in front
of the front camera.
Close the hood, rem ove the sticker,
etc. to clear the obstruction.
When “Pre-Collisio n System Radar
In Self Calibration Unavailable See

LTA (Lane Tracing
Assist)
While driving on a road with
clear white (yellow) lane
lines, the LTA system warns
the driver if the vehicle may
deviate from the current
lane or course
*, and also
can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*. Also, while the
dynamic radar cruise con-
trol with full-speed range
( P.366) is operating, this
system will operate the
steering wheel to maintain
the vehicle’s lane position.
The LTA system recognizes
white (yellow) lane lines or a
course
* using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the side of the road, such as
grass, soil, or a curb
