Driving
2Eco drive mode
Helps the driver accelerate in an
eco-friendly manner and improve fuel
economy through moderate throttle char-
acteristics and by controlling the operation
of the air conditioning system (heat-
ing/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.
3Sport mode
•SPORT S mode
Controls the transmission and engine to
provide quick, powerful acceleration. Also,
gear shift timing is co ntrolled to suit sporty
driving, making this mode is suitable for
when agile driving 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 down shift 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 pow-
erful 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.
■Operation of the air conditioning sys-
tem in Eco drive mode
Eco drive mode controls the heating/cool-
ing operations and fan speed of the air con-
ditioning system to enhance fuel efficiency
(  P.213). To improve air conditioning per-
formance, adjust the fan speed or turn off
Eco drive mode.
■Automatic deactivation of sport mode
and custom mode
If the engine switch is turned off after driv-
ing in sport mode or custom mode, the
drive mode will be changed to normal
mode.
■Driving mode pop-up display (vehicles
with a 10.3-inch display)
