■High beam automatic turning on or off conditions
●When all of the following conditions are fulfilled, the high beam will be auto-
matically turned on (after approximately 1 second):
• The vehicle speed is approximately 30 - 40 km/h (19 - 25 mph)
* 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 fulfilled, the high beam will be automat-

*.
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.
*: The vehicle speed at which the high beams are automatically turned on/

■Front camera detection information
●The high beam may not be automatically turned off in the following situa-
tions:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead vehicles have no lights
●The high beam may be turned off if a vehicle ahead that is using fog lights
without using the headlights is detected.
●House lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beam to switch to the low beams, or the low beams to
remain on.
●The following factors may affect the amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of vehicles 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 (gradient, curve, condition of the road surface
etc.)
• The number of passengers and amount of luggage
●The high beam may be turned on or off when the driver does not expect it.
●Bicycles or similar objects may not be detected.

Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is
necessary, 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 stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pushing the
cruise control lever up or depressing the accelerator pedal (start-off opera-
tion) will resume follow-up cruising. If the start-off operation is not per-
formed, system control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 80 km/h (50 mph) or more, the vehicle will
accelerate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane
is to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

BSM (Blind Spot Monitor)
The Blind Spot Monitor is a system that has 2 functions;
●The Blind Spot Monitor function
Assists the driver in making the decision when changing lanes
●The Rear Crossing Traffic Alert function
Assists the driver when backing up
These functions use same sensors.
Outside rear view mirror indicators
Blind Spot Monitor function:
When a vehicle is detected in the blind spot, the outside rear view mirror
indicator comes on while the turn signal lever is not operated. If the turn
signal lever is operated toward the detected side, the outside rear view
mirror indicator flashes.
Rear Crossing Traffic Alert function:
When a vehicle approaching from the right or left rear of the vehicle is
detected, the outside rear view mirror indicators flash.

■Function summary
When departing from a parallel parking position, select the direction
you would like to depart in, and steering wheel operation assist con-
trol will be provided to guide the vehicle to a position from which
you can take off.
With the shift position in P,
press the S-IPA switch,
select exit parallel parking
assist mode, and then oper-
ate the turn signal lever to
select the desired departure
direction.
Steering wheel auto opera-
tion starts when the shift
position is changed accord-
ing to guidance provided by
the system.
A sound is issued and a display is shown to notify you when the
vehicle reaches a position from which you can take off.
Depending on the condition of the parking space, guidance to starting
points for moving forward and backing up, as well as the steering wheel
auto operation, are repeated any time multi-turn maneuvering is neces-
sary from the time the steering wheel auto operation begins in step
up until the vehicle reaches a position from which it can take off.
