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 RCTA function is only a supplementary function which alerts the driver that a vehi-
cle is approaching from the right or left at the rear of the vehicle. As the RCTA function
may not function correctly under certain cond itions, 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 5 mph (8 km/h).
●The approaching vehicle speed is between approximately 5 mph (8 km/h) and 18 mph
(28 km/h).

Normal mode
Provides an optimal balance of fuel ec onomy, quietness, and dynamic perfor-
mance. Suitable for city driving.
Press the switch to change the driving mode to normal mode when Eco drive mode or
sport mode is selected.
Eco drive mode
Helps the driver accelerate in an eco-fr iendly manner and improve fuel econ-
omy through moderate throttle charact eristics and by controlling the opera-
tion of the air conditioning system (heating/cooling).
When not in Eco drive mode, if the driving mode select switch is turned to the left, the
Eco drive mode indicator will come on.
Sport mode
Controls the transmission and engine to provide quick, powerful acceleration.
This mode also changes the steering feel, making it suitable for when agile
driving response is desired, such as wh en driving on roads with many curves.
When not in sport mode, if the driving mode select switch is turned to the right, the
“SPORT” indicator will comes on.

as when driving on roads with many curves.
When not in SPORT S mode, if the driving mode select switch is turned to the
right, the “SPORT S” indicator will come on.
•SPORT S+ mode
Helps to ensure steering performanc e and driving stability by simultane-
ously controlling the steeri ng and suspension in addition to the transmis-
sion and engine. Suitable for sportier driving.
When in SPORT S mode, if the driving mode select switch is turned to the right,

When not in SPORT S mode, if the driving mode select switch is turned to the
right, the “SPORT S” indicator will come on.
•SPORT S+ mode
Provides earlier downshift timing than SPORT S mode in order to maintain
a high engine speed and provides faster gear changes. This mode also
changes the steering feel, suspension control and VDIM control, making it
suitable for powerful sporty driving.
When in SPORT S mode, if the driving mode select switch is turned to the right,
the “SPORT S+” indicator will come on.

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, co ntributing to a more stable ride.
The active rear wing can be controlled using a switch.
