When Driving- Page 277



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, it does not
cancel even if the selector lever is
operated and any intended engine
braking does not occur. If deceleration
is required, lower the set speed or
depress the brake pedal.



You might hear the sound of the
automatic brakes operating; however, it
does not indicate a problem.



The brake lights turn on while the TJA
automatic braking is operating.



Under the following conditions, the TJA
may not be able to detect white (yellow)
lines 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 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.



The tire pressures are not adjusted to
the specified pressure.



Tires other than standard tires are
equipped.



The vehicle is driven through an
intersection, a junction, or a fork in
the road.



While white (yellow) lane lines cannot
be detected due to road or weather
conditions.



The surrounding brightness suddenly
changes such as when entering or
exiting a tunnel.



The illumination of the headlights is
weakened because of dirt or the
optical axis is deviated at night.



Back-light is reflected off the road
surface or the road surface is wet and
shiny after rain.
