When driving
■Reverse warning buzzer
When  shifting  into  R,  a  buzzer  will  sound  to  inform  the  driver  that  the  shift
position is in R.
■Automatically P position selection function
When the shift position  is in a position other than P, pressing the “POWER”
switch  with  the  vehicle  stopped  completely  will  cause  the  shift  position  to
change to P automatically, and then the “POWER” switch will turn off.
■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. ( oP.   6 0 1 )
■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  gaso-
line-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, shift the shift position to D.
■When driving with cruise control or radar cruise control activated
Even if switching the driving mode to power mode with the intent of enabling
engine  braking,  engine  braking  will  not  activate  because  cruise  control  or
radar cruise control will not be canceled.

■When canceling Eco drive mode/power mode
●Press the switch again. Also, power mode will be canceled automatically
when  the  “POWER”  switch  is  turned  off.  However,  Eco  drive  mode  will
not  be  canceled  automatically  until  the  switch  is  pressed,  even  if  the
“POWER” switch is turned off.
●When  in  Eco  drive  mode,  if  the  power  mode  switch  is  pressed  or  the
operation is reversed, the mode will switch to that of the last switch to be
pressed.
