■
Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the hybrid system is not operating) for more than an hour with the
shift position in P, the “POWER” switch will automatically turn off. However,
this function cannot entirely prevent the 12-volt battery from discharging. Do
not leave the vehicle with the “POWER” switch in ACCESSORY or ON mode
for long periods of time when the hybrid system is not operating.

■ Electronic key battery depletion
P. 127
■ When the ambient temperature is low, such as during winter driving
conditions
The “READY” indicator may flash for a long time when the hybrid system\
is
starting. Driving will become possible once the “READY” indicator has illumi-
nated. Wait until the “READY” indicator has illuminated.

■When the “POWER” switch in dicator flashes in amber
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer immediately.
■ If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the “POWER”
switch with the shift position in P and the brake pedal depressed, contact
your Toyota dealer immediately.

■ Operation of the “POWER” switch
●When operating the “POWER” switch, one short, firm press is enough. If
the switch is pressed improperly, the hybrid system may not start or the
“POWER” switch mode may not change. It is not necessary to press and
hold the switch.
● If attempting to restart the hybrid system immediately after turning the
“POWER” switch off, the hybrid system may not start in some cases.
After turning the “POWER” switch off, please wait a few seconds before
restarting the hybrid system.

Shift position indicator
The position of the frame on the shift position indicator changes in
accordance with the current shift position.
When any shift position other than D or B is selected, the arrow toward
B and B position indicator disappear from the shift position indicator.
When selecting the shift position, make sure that the shift position has
been changed to the desired position by checking the shift position indica-
tor provided on the instrument cluster.
■ Shift position purpose
*: For good fuel economy and noise reduction, the D position should usu-
ally be used.

When driving
■
Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator 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
minimized.
When the “ECO MODE” switch is pressed, the “ECO MODE” indicator
comes on.
Power mode
Use when high levels of response and feeling are desirable,
such as when driving in mountainous regions or when overtak-
ing.
When the power mode switch is pressed, the power mode indicator
comes on.

When driving
■
Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 251) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ 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 hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
However, immediately after turning the “POWER” switch to ON mode,
the shift position may not change to N.
● When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
● When the “READY” indicator is flashing, the shift position cannot be
changed from P to other position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.
● The shift position can only be changed to B directly from D.

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. ( P. 601)
■ 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.
