■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 generated 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
pressed, the “ECO MODE”
indicator comes on in the meter.
Po w e r m o d e
Suitable when the vehicle needs
to drive powerfully or travels in
mountainous areas.
When the power mode switch is
pressed, the “PWR MODE”
indicator comes on in the meter.

■For the shift positions
●When the “POWER” switch is off, the shift position cannot be changed.
●When the “POWER” switch is in ON mode, the shift position can only be
changed to N.
●When the “READY” indicator is on, the shift position can be changed from P to
D, N o r R .
●The shift position can only be changed to B directly from D.
In addition, if the shift position is changed in any of the following situations, the
buzzer will sound and the shifting operation will be disabled or the shift position will
automatically change to N. When this happens, select an appropriate shift position.
● Situations where the shifting operation will be disabled:
• When the shift lever is changed from P to another position without depress-
ing the brake pedal.
• When the shift position is changed from P or N to B.
● Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.
• When shift position R is selected when the vehicle is moving forward.
• When shift position D is selected when the vehicle is moving in reverse.
• When the shift position is changed from R to B.
■Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift position is
in R.
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply engine
braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline- fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will become low.
Usually, select the D position.
