mance.
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc., on the sur-
face of the lights.
●Do not modify the suspension,
etc. If the suspension, etc.,

■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.
●When the follow-up cruising dis-
play is displayed ( P.248) and
the preceding vehicle changes
lanes. (Your vehicle may follow
the preceding vehicle and also

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may
become shorter.
WARNING
●When weather conditions are
bad enough that they may pre-
vent the sensors from detecting
correctly (fog, snow, sand-
storm, heavy rain, etc.)

frequent repeated acceleration
and deceleration

vehicle-to-vehicle distance con-
trol mode may not function cor-
rectly
In the case of the following condi-
tions, operate the brake pedal (or
accelerator pedal, depending on the
situation) as necessary.
As the sensor may not be able to
correctly detect vehicles ahead, the
system may not operate properly.
●When the road curves or when the
lanes are narrow
●When steering wheel operation or
your position in t he lane is unsta-
ble
●When the vehicle ahead of you
decelerates suddenly

rounded by a structure, such as in
a tunnel or on a bridge

vent sensors from sufficiently
detecting the trailer.
■Trailer Length Detection (TLD)
●Once a trailer is detected and if
the trailer length in the meter is
selected as “Auto”, the TLD func-
tion will estimate the
trailer length
using the Blind Spot Monitor sen-
sors. In order to estimate
the trailer length
with TLD function and detection
area, make at least two 90 degree
turns.
If the trailer length is entered manu-
ally via multi-information display
input, the detection area is also
adjusted to exceed the length of the
trailer.
●Depending on some trailer types
and the dimensions of the trailer
TMW performance may be
degraded.
■Vehicles that can be detected by the Blind Spot Monitor
The Blind Spot Monitor uses rear side radar sensors to detect the fol-
lowing vehicles traveling in adjacent lanes and advises the dri ver of
the presence of such vehicles v ia the indicators on the outside rear
view mirrors.
When not towing a trailer

■To ensure the system can
operate properly
Observe the following precau-
tions.
Failing to do so may result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not damage the sensors,
and always keep them clean.
