SPORT mode
SPORT mode provides sporty but firm riding.
In SPORT mode, the fuel
efficiency may decrease.
• When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.
• Whenever the engine is restarted,
the drive mode will revert back to
NORMAL mode. If SPORT mode is
desired, re-select SPORT mode.
• When SPORT mode is activated:
-The engine RPM will tend to remain
raised over a certain length of time
even after releasing the accelerator
-Upshifts are delayed when
accelerating
SMART mode
SMART mode selects the proper driving mode among ECO,
NORMAL and SPORT by judging
the driver's driving habits (i.e.
mild or dynamic) from the
brake pedal depression or the
steering wheel operation.
• Press the DRIVE MODE button to
activate SMART mode. When SMART
mode is activated, the indicator
illuminates on the instrument cluster.
• The vehicle starts in SMART mode,
when the engine was turned OFF in
SMART mode.
• SMART mode automatically controls
gear shifting patterns, engine torque,
in accordance with the driver's driving
habits.
Information
• When your vehicle drive mode
is selected to SMART mode, the
driving mode varies according to
your acceleration pedal input. When
your vehicle is in SMART mode and
your driving style is such that your
acceleration pedal input is gradual,
the drive mode will maximize fuel
efficiency. Note, however, the actual
fuel efficiency may vary according
to certain driving conditions (uphill/
downhill grade) and vehicle speed.
• When your vehicle is in SMART
mode and your driving style is more
aggressive such that your acceleration
pedal input is more abrupt, the drive
mode will change to reflect a more
SPORT driving characteristic. Note
that while you are driving this way, fuel
economy may be adversely affected.
