When driving
■Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco mode
Suitable for improving the fuel
economy, because the torque
corresponding to the accelera-
tor pedal depression amount
can be gener
ated more
smoothly than it is in normal
conditions and the operation of
the air conditioning system will
be minimized.
When the Eco mode switch is
pr
essed, the “ECO MODE”
indicator comes on in the meter.
Power mode
Suitable when the vehicle needs
to drive powerfully or travels in
mountainous areas.
When the power mode switch is
pr
essed, the “PWR MODE”
indicator comes on in the meter.
