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.

RC F_U 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.

ally. (The active rear wing retracts when it is raised and raises when retracted.) ■
Operation by switch
* : Press and hold the switch until the indicator tu rns off. If the switch is released while the
active rear wing is moving, it will retu rn 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 situatio ns operation of the acti ve rear wing will stop:●
The engine switch is turned off whil e 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 unusua l manner causing it to stop at an irregular
position.
In such cases, pressing the acti ve rear wing switch will fully raise the active rear wing. Or,
begin driving the vehicle and the active rear wing will raise automatically when the vehi-
cle speed reaches 16 mph (25 km/h). ■
Restoring automatic operatio n after the active rear wing is operated manually
If the active rear wing is operated manua lly, 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. 478)■

RC F_U With the engine switch in IGNITION
ON mode, pressing the TVD switch
changes the TVD control mode. The current TVD control mode will be
displayed on the meters.
STANDARD mode
This is the default mode and pro-
vides an optimum balance of driving
agility and stability.
SLALOM mode
This mode emphasizes enhanced
steering response.
TRACK mode
This mode emphasizes stability for
high speed sporty driving.
The multi-information display shows the di stribution of driving force between the
right and left rear wheels. (  P. 118)TVD (Torque Vectoring Differential) 
 : If equippedThe TVD system distributes driving force (torque) between the right and left
rear wheels automatically. This syst em contributes to enhanced steering
response while cornering and increased traction when exiting a corner, pro-
viding an agile driving experience.

Automatic cancelation of the selected TVD control mode
SLALOM and TRACK mode are canceled when the engine switch is turned off. When
the engine switch is turned to IGNITION ON mode, the TVD system will be in STAN-
DARD mode. ■
Automatic disabling of the TVD system
If a malfunction is de tected in the TVD system, a warn ing message will be displayed on
the multi-information display (  P. 474) and the TVD system will be disabled automati-
cally. If the system is disabled, driving force will not be distributed by the TVD but through
normal differential operation. ■
To protect the system
The TVD fluid temperature may become excessively high when driving for a long time
under extremely high load conditions. In th is case, a warning messa ge will be displayed
on the multi-information display. (  P. 474)

Cautions regarding the use of the system
The driver is solely responsible for safe driv ing. Do not overly rely on the TVD system.
Always drive safely, taking care to observe your surroundings.
