RC F_U When constant speed control mode is se lected, your vehicle will maintain a set
speed without controlling the vehicle-to-veh icle distance. Select this mode only
when vehicle-to-vehicle distance control mode does not function correctly due
to a dirty radar sensor, etc.
With the cruise control off, press and
hold the “ON/OFF” button for 1.5
seconds or more. Immediately after the “ON/OFF” but-
ton is pressed, the radar cruise control
indicator will come on. Afterwards, it
switches to the cruise control indicator.
Switching to constant speed control
mode is only possible when operating
the lever with the cruise control off.

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 tu rned 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.Driving mode select switch The driving modes can be selected to suit driving condition.

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.

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)
WARNING ■
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.
