LDA (Lane Departure Alert)
Summary of function
While driving on a road that has lane markers, this system recognizes
the lane markers using a camera as a sensor to alert the driver when
the vehicle deviates from its lane.
If the system judges that the vehicle has deviated from its lane, it
alerts the driver using a buzzer and indications on the multi-informa-
tion display.
Front sensor
Turning the LDA system on
Press the LDA switch to activate
the system.
The LDA indicator will come on.
Press the switch again to turn the
LDA system off.
The LDA system will remain on or
off even if the engine switch is
turned to “ON” position (vehicles
without smart entry & start sys-
tem) or the “ENGINE START
STOP” switch is turned to IGNI-
TION ON mode (vehicles with
smart entry & start system).

■ Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
● The turn signal lever is operated.
● The vehicle speed deviates from the operating range of the LDA system
functions.
● When the lane lines cannot be recognized while driving.
● When the lane departure warning sounds.
The lane departure warning function will not operate again for a several
seconds after it has been activated, even if the vehicle leaves the lane
again.
■ The lane departure warning
Depending on the audio system sound le vel or air conditioning fan noise
while the audio system or air conditioning system is in use, it may be difficult
to hear the warning sound.
■ After the vehicle has been parked in the sun
The LDA may not be available and a warning message ( P. 551) will be dis-
played for a while after driving has started. When the temperature in the
cabin decreases and the temperat ure around the front sensor (P. 283)
becomes suitable for its operation, the functions will begin to operate.
■ If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane mark-
ers could not be recognized.
■ Conditions in which the function may not operate correctly
In the following situations, the front sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly.
However, this does not indicate a malfunction.
● When driving through an area, such as a tollbooth, a crossing or before a
ticket checkpoint
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide

Activating the Automatic High Beam system
Push the lever away from you
with the headlight switch in
position.
The Automatic High Beam indi-
cator will come on when the
headlights are turned on auto-
matically to indicate that the sys-
tem is active.
: If equipped
The Automatic High Beam uses an in-vehicle front sensor to assess
the brightness of streetlights, the lights of oncoming and preceding
vehicles, etc., and automatically tu rns high beam on or off as neces-
sary.

■ Front sensor detection information
● High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another
• When oncoming or preceding vehicles are hidden from sight due to
repeated curves, road dividers or roadside trees
● High beam may be turned off if an oncoming vehicle that is using fog
lights without using the headlights is detected.
● House lights, street lights, red traffic signals, and illuminated billboards or
signs may cause the high beam to turn off.
● The following factors may affect the amount of time taken to turn high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and
preceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle only has operational lights on
one side
• When a oncoming or preceding vehicle is a two-wheeled vehicle

● High beam may be turned on or off when unexpected by the driver.
● In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestri-
ans to the high beam. Therefore, you should consider turning the high
beams on or off manually rather than relying on the Automatic High
Beam system.
• In bad weather (rain, snow, fog, sandstorms, etc.)
• The windshield is obscured by fog, mist, ice, dirt, etc.
• The windshield is cracked or damaged.
• The front sensor is deformed or dirty.
• The front sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail
