The areas that vehicles can be detected in are outlined below.
The range of each detection area is:
Approximately 0.5 m (1.6 ft.) to 3.5 m (11.5 ft.) from either side of the vehicle*
*: The area between the side of the vehicle and 0.5 m (1.6 ft.) from the side of the vehicle
cannot be detected.
Approximately 1 m (3.3 ft.) forward of the rear bumper
Approximately 3 m (9.8 ft.) from the rear bumper
Approximately 3 m (9.8 ft.) to 60 m (197 ft.) from the rear bumper*
*: The greater the difference in speed between your vehicle and the detected vehicle is,
the farther away the vehicle will be detect ed, causing the outside rear view mirror
indicator to illuminate or flash.
BSM function detection areas
WARNING
■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The BSM function is a supplementary function which alerts the driver that a vehicle is in a blind spot of the outside rear view mirrors or is approaching rapidly from behind intoa blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is
safe to change lanes, over reliance could lead to an accident resulting in death or seri- ous injury.
As the system may not function correctly under certain conditions, the driver’s own
visual confirmation of safety is necessary.

■The BSM function is operational when
The BSM function is operational when a ll of the following conditions are met:
●The BSM main switch is on.
●The shift lever is in a position other than R.
●The vehicle speed is greater than approximately 16 km/h (10 mph).
■The BSM function will detect a vehicle when
The BSM function will detect a vehicle present in the detection area in the following situ-
ations:
●A vehicle in an adjacent lane overtakes your vehicle.
●Another vehicle enters the detection area when it changes lanes.
■Conditions under which the BSM function will not detect a vehicle
The BSM function is not designed to detect the following types of vehicles and/or objects:
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles traveling in the opposite direction
●Guardrails, walls, signs, parked vehi cles and similar stationary objects*
●Following vehicles that are in the same lane*
●Vehicles traveling 2 lanes away from your vehicle*
*: Depending on the conditions, detection of a vehicle and/or object may occur.

■Conditions under which the BSM function may not function correctly
●The BSM function may not detect vehicles correctly in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround-
ing area • When mud, snow, ice, a sticker, etc. is covering the sensor or surrounding area onthe rear bumper
• When driving on a road surface that is wet with standing water during bad weather, such as heavy rain, snow, or fog• When multiple vehicles are approaching wi th only a small gap between each vehicle
• When the distance between your vehicle and a following vehicle is short • When there is a significant difference in speed between your vehicle and the vehiclethat enters the detection area
• When the difference in speed between your vehicle and another vehicle is changing • When a vehicle enters a detection area traveling at about the same speed as yourvehicle
• As your vehicle starts from a stop, a vehicle remains in the detection area • When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.
• When driving on roads with sharp bends, consecutive curves, or uneven surfaces • When vehicle lanes are wide, or when driving on the edge of a lane, and the vehiclein an adjacent lane is far away from your vehicle
• When a bicycle carrier or other accessory is installed to the rear of the vehicle • When there is a significant difference in height between your vehicle and the vehiclethat enters the detection area
• Immediately after the BSM main switch is turned on
●Instances of the BSM function unnecessarily detecting a vehicle and/or object may
increase in the following situations:
• When the sensor is misaligned due to a strong impact to the sensor or its surround-
ing area • When the distance between your vehicle and a guardrail, wall, etc. that enters thedetection area is short
• When driving up and down consecutive steep inclines, such as hills, dips in the road, etc.• When vehicle lanes are narrow, or when driving on the edge of a lane, and a vehicle
traveling in a lane other than the adjacent lanes enters the detection area • When driving on roads with sharp bends, consecutive curves, or uneven surfaces• When the tires are slipping or spinning
• When the distance between your vehicle and a following vehicle is short • When a bicycle carrier or other accessory is installed to the rear of the vehicle

The RCTA function uses radar sensors to detect vehicles approaching from the
right or left at the rear of the vehicle and alerts the driver of the presence of such
vehicles by flashing the outside rear view mirror indicators and sounding a
buzzer.

■Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to observe your surroundings.
The RCTA function is only a supplementary fu nction which alerts the driver that a vehi- cle is approaching from the right or left at th e rear of the vehicle. As the RCTA function may not function correctly under certain conditions, the driver’s own visual confirma-
tion of safety is necessary. Over reliance on this function may lead to an accident resulting death or serious injury.

The areas that vehicles can be detected in are outlined below.
The buzzer can alert the driver of faster vehicles approaching from farther away.
Example:
■The RCTA function is operational when
The RCTA function operates when all of the following conditions are met:
●The BSM main switch is on.
●The shift lever is in R.
●The vehicle speed is less than approximately 8 km/h (5 mph).
●The approaching vehicle speed is between approximately 8 km/h (5 mph) and 28 km/h (18 mph).

■Conditions under which the RCTA function will not detect a vehicle
The RCTA function is not designed to dete ct the following types of vehicles and/or objects:
●Vehicles approaching from directly behind
●Vehicles backing up in a parking space next to your vehicle
●Guardrails, walls, signs, parked vehi cles and similar stationary objects*
●Small motorcycles, bicycles, pedestrians, etc.*
●Vehicles moving away from your vehicle
●Vehicles approaching from the parking spaces next to your vehicle*

●Instances of the RCTA function unnecessarily detecting a vehicle and/or object may increase in the following situations:
• When a vehicle passes by the side of your vehicle
• When the distance between your vehicle and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may reflect electrical waves toward the rear of the vehicle, is short

The RC F is equipped with an active rear wing that operates automatically while
the vehicle is being driven. This active rear wing enhances aerodynamic perfor-
mance, especially at high speeds, contributing to a more stable ride.
The active rear wing can be controlled using a switch.

Operate the active rear wing switch to raise/retract the active rear wing manu-
ally. (The active rear wing retracts when it is raised and raises when retracted.)
■Operation by switch
*: Press and hold the switch unti l the indicator turns off. If the switch is released while the
active rear wing is moving, it will return to the raised position automatically.
■The active rear wing can be operated when
●The engine switch is in IGNITION ON mode.
●The trunk is closed.
■Conditions which stop the operation of the active rear wing
In the following situations operation of the active rear wing will stop:
●The engine switch is turned off while the active rear wing is operating.
●The trunk is opened while the active rear wing is operating.
●The raising operation of the active rear wing is interrupted by an object, etc.
●The active rear wing is operated in an unusual manner causing it to stop at an irregular
position.
In such cases, pressing the active rear wing switch will fully raise the active rear wing. Or, begin driving the vehicle and th e active rear wing will raise automatically when the vehi-
cle speed reaches 25 km/h (16 mph).
■Restoring automatic operation after the active rear wing is operated manually
If the active rear wing is operated manual ly, automatic operation will resume according to the vehicle speed.
■When there is a malfunction in the system
A warning message will be displayed on the multi-information display. (P. 609)
■Customization
The active rear wing can be held at the raised position or retracted position.
