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.
