4-2. Driving procedures
Driving
*1: To improve fuel efficiency and reduce
noise, set the shift position in D for nor-
mal driving. You can choose gear range
suitable for your driving situation by
operating the paddle shift switches.
*2: Any gear range can be fixed when driv-
ing in M mode.
■For the shift positions
●When the engine switch is off or in ACCESSORY mode, the shift position
cannot be changed.
●When the engine switch is in IGNITION
ON mode, the shift position can only be changed to N.
●When the engine is running, the shift position can be changed from P to D, N or R.
●The shift position can only be changed to
M directly from D.
In addition, if an attempt is made to change
the shift position by moving the shift lever or by pressing the P position switch in any of the following situations, the buzzer will
sound and the shifting operation will be dis- abled 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 an attempt is made to change the shift position from P to another position
by moving the shift lever without depress- ing the brake pedal.• When an attempt is made to change the
shift position from P or N to M by moving the shift lever.• When the P position switch is pressed
while the vehicle is running.*1
●Situations where the shift position will automatically change to N:• When an attempt is made to select the R
position by moving the shift lever when
the vehicle is moving forward.*2
• When an attempt is made to select the D position by moving the shift lever when
the vehicle is moving in reverse.*3
• When the shift position is changed from R to M
●If N is selected while driving at a certain speed, even if the shift lever is not held in
the N position, the shift position changes to N. In this situation, the buzzer sounds and a confirmation message is displayed
on the multi-information display to inform the driver that the shift position has changed to N.
*1: Shift position may be changed to P when
driving at extremely low speeds.
*2: Shift position may be changed to R when
driving at low speeds.
*3: Shift position may be changed to D
when driving at low speeds.

4-2. Driving procedures
■Shifting 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.
 When selecting the shift position,
make sure that the shift position has
been changed to the desired posi-
tion by checking the shift position
indicator provided on the instru-
ment cluster.
 The shift position cannot be
changed from P to M directly.
■Automatic P position selection function
In the following situations, the shift position is automatically changed to P.
●When pressing the engine switch with the vehicle stopped while the engine switch is
in IGNITION ON mode and the shift position is in a positi on other than P (after the shift position has changed to P, the
engine switch will turn off)*
●When the vehicle is stopped after the engine has been stopped in an emer-gency while driving
●When voltage of the 12-volt battery drops while the shift position is in a posi-
tion other than P
*: When the engine switch is pressed while
driving at extremely slow speeds, such as
immediately before stopping the vehicle,
the shift position may automatically
change to P. Make sure that the vehicle is
completely stopped before pressing the
engine switch.
■If the shift position cannot be shifted
from P
There is a possibility that the 12-volt battery
is discharged. Check the 12-volt battery in this situation. ( P.392)
WARNING
■P position switch
●Do not press the P position switch
while the vehicle is moving. If the P position switch is pressed when driving at very low speeds (for exam-
ple, directly before stopping the vehi- cle), the vehicle may stop suddenly when the shift position switches to P,
which could lead to an accident.
●In order to prevent the shift position from accidentally being changed, do not touch the P position switch when
not using them.
NOTICE
■Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-cession.
The system protection function may acti- vate and it will not be temporarily possi-
ble to shift the shift position other than P. If this happens, please wait for a while before attempting to change the shift
position again.
