RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)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
•SPORT S mode
Controls the transmission and engine to provide quick, powerful accelera-
tion. Also, gear shift timing is controlle d to suit sporty driving, making this
mode is suitable for when agile drivin g response is desired, such 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
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. Function Setting
