Stationary objects (stopped vehicles, obstructions)



If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.



If there is a structure on the road or an object (such as a monorail) at a low height off the
ground in front of the vehicle, the system may operate. Therefore, do not use the TJA.



Do not use the TJA under conditions in which close proximity warnings are frequently
activated.



If it is necessary to accelerate for a lane change or the vehicle ahead brakes suddenly
causing you to close in on the vehicle rapidly, accelerate using the accelerator pedal or
decelerate using the brake pedal depending on the conditions.



While the TJA is in use, any intended engine braking does not occur even if you shift the
selector lever. If deceleration is required, lower the vehicle speed setting or depress the
brake pedal.



While braking by the TJA control is operating, you might hear an operation sound,
however, this does not indicate a problem.



The brake lights turn on while braking by the TJA control is operating, however, they may
not turn on while the vehicle is on a down slope at the set vehicle speed or traveling at a
constant speed and following a vehicle ahead.



Under the following conditions, the TJA may not be able to detect white (yellow) lines or
vehicles ahead correctly and the TJA may not operate normally.



The forward sensing camera (FSC) cannot recognize the area in front of the vehicle due
to soiling or fog.



The white (yellow) lane lines are less visible because of dirt or paint flaking.



White (yellow) lane lines or vehicles ahead are less visible because of bad weather
(rain, fog, or snow).



The vehicle is driven on a temporary lane or section with a closed lane resulting from
construction where there might be multiple white (yellow) lane lines, or they are
interrupted.



The camera picks up an obscure line, such as a temporary line being used for
construction, or because of shade, unmelted snow, or grooves filled with water.



The road surface is wet and shiny after rain, or there are puddles on the road.



Heavy luggage is loaded in the luggage compartment or on the rear seat causing the
vehicle to tilt.



A vehicle in front of your vehicle is running near a white (yellow) lane line making it
less visible.



The windshield is dirty or foggy.

Lane-keep Assist System (LAS) & Lane Departure

Warning System (LDWS)

*

The LAS & LDWS alerts the driver that the vehicle may be deviating from its lane and it
provides steering assistance to help the driver stay within the vehicle lanes.
The Forward Sensing Camera (FSC) detects the white lines (yellow lines) of the vehicle
lane in which the vehicle is traveling and if the system determines that the vehicle may
deviate from its lane, it operates the electric power steering to assist the driver's steering
operation. The system also alerts the driver by activating a lane departure warning sound,
vibrating the steering wheel, and indicating an alert in the display. Use the system when you
drive the vehicle on roads with white (yellow) lines such as expressways and highways.
Refer to Forward Sensing Camera (FSC) on page 4-256.



If the steering wheel, accelerator pedal, or brake pedal is operated abruptly and the
vehicle moves close to a white (yellow) line, the system determines that the driver is
making a lane change and the LAS & LDWS operation is temporarily canceled. The LAS
& LDWS becomes operational again when the system detects white (yellow) lane lines
while the vehicle is being driven normally within its vehicle lane.



If the vehicle deviates from its lane repeatedly within a short period of time, the LAS &
LDWS may not operate.



When white (yellow) lane lines are not detected, the LAS & LDWS does not operate.



Under the following conditions, the LAS & LDWS may not be able to detect white (yellow)
lane lines correctly and it may not operate normally.



If an object placed on the dashboard is reflected in the windshield and picked up by the
