■Shift position purpose
*: For good fuel economy and noise redu ction, the D position should usually
be used.
■ P position switch
The shift position can be changed to P through use of the P position
switch.
Fully stop the vehicle and keep
depressing the brake pedal, and
then press the P position switch.
When the shift position is
changed to P, the switch indica-
tor comes on.
Check that the P position indi-
cator is illuminated on the shift
position indicator.
●Changing the shift position from P to other positions:
• While depressing the brake pedal firmly, operate the shift lever. If the
shift lever is operated without depressing the brake pedal, the buzzer
will sound and the shifting operation will be disabled.
• The shift position cannot be changed from P to B directly.

■Selecting a driving mode
The following modes can be sele cted to suit driving conditions:
Eco drive 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
(heating/cooling) will be mini-
mized.
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 “PWR MODE”
switch is pressed, the “PWR
MODE” indicator comes on in
the meter.

■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.
■Using air conditioning in Eco drive mode
The Eco drive mode controls heating/cooling and fan speed operation to improve
fuel consumption. When you want to improve the effectiveness of the air condition-
ing system, adjust the fan speed or cancel the Eco drive mode.
For more information, refer to the “Navigation System Owner’s Manual”.
■Power mode automatic deactivation
Power mode is automatically deactivated if the “POWER” switch is turned off after
driving in power mode.
■Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features →P. 5 8 4 )
CAUTION
■When driving on slippery road surfaces
Do not accelerate or change the shift position suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in
an accident.
■For the shift lever
Do not hang anything on the shift lever.
Doing so could prevent the shift lever fr om returning to position, causing unex-
pected accidents to occur when the vehicle is in motion.
