tions are met, the high beams will
be turned on automatically (after
approximately 1 second):
• The vehicle speed is 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.
• There are few streetlights on the
road ahead.
●If any of the following conditions
are met, the high beams will turn

■Front camera detection infor-
mation
●The high beams may not be auto-
matically turned off in the following
situations:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves,
road dividers or roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead
are not on
●The high beams may be turned off
if a vehicle ahead that is using fog
lights without its headlights turned
on is detected.
●House lights, street lights, traffic
signals, and illuminated billboards
or signs and other reflective
objects may cause the high
beams to change to the low
beams, or the low beams to
remain on.
●The following fact ors may affect
the amount of time taken for the
high beams to turn on or off:
• The brightness of the headlights, fog lights, and ta il lights of vehi-
cles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has
operational lights on one side
• When a vehicle ahead is a two- wheeled vehicle
• The condition of the road (gradi- ent, curve, condition of the road
surface, etc.)
• The number of passengers and amount of luggage in the vehicle
●The high beams may turn on or off
unexpectedly.
●Bicycles or similar vehicles may
not be detected.
●In the following situations the sys-
tem may not be able to correctly
detect the surrounding brightness
level. This may cause the low
beams to remain on or the high
beams to flash or dazzle pedestri-
ans or vehicles ahead. In such a
case, it is necessary to manually
switch between the high and low
beams.

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.326, 334).
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.

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-vehicl e
distance switch.
When driving on downhill slopes, t he vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected runni ng ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you st ops, your vehicle will also stop (vehicle is
stopped by system control). Afte r the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not pe rformed, system
