When driving
■
When the P position cont rol system malfunctions
The “POWER” switch will not be able to be turned off. In such a case, the
switch can be turned off after applying the parking brake.
Have the vehicle inspected by your Toyota dealer immediately.
■ Ending display
When the “POWER” switch is turned off, each of the following will be dis-
played on the multi-information display, and will extinguish after approxi-
mately 30 seconds.
● The driving distance, driving time and consumption since the hybrid sys-
tem was started.
● The odometer
● The clock
CAUTION
■When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any cir-
cumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehi-
cle, press and hold the “POWER” switch for more than 2 seconds, or press it
briefly 3 times or more in succession. ( P. 607)
However, do not touch the “POWER” switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, but the power assist to these systems will \
be lost.
This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.

NOTICE
■To prevent 12-volt battery discharge
● Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If the hybrid system is off, but the indicator on the “POWER” switch is illu-
minated, this indicates that the “POWER” switch is still turned on. When
exiting the vehicle, always check that the “POWER” switch is off.
■ Symptoms indicating a malfunct ion with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact your Toyota dealer immediately.

When driving
Hybrid transmission
Select a shift position appropriate for the driving conditions.
■Shifting the shift lever
Shift lever
Operate the shift lever gently and ensure correct shifting operation.
When shifting to the D or R positions, move the shift lever
along the shift gate.
To shift to the N position, slide the shift lever to the left and hold
it. The shift position will change to N.
Shifting to B is only possible when shift position D is selected.
The shift lever will always return to this original position after a
shifting operation.
When shifting from P to N, D or R, from D to R, or from R to D, ensure
that the brake pedal is being depressed and the vehicle is stationary.

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.

P position switch■ When shifting the shift position to P
Fully stop the vehicle and set the
parking brake, and then press
the P position switch.
When the shift position is
changed to P, the indicator comes
on.
Check that the P position is illumi-
nated on the shift position indica-
tor.
■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 wi thout depressing the brake pedal,
the buzzer will sound and the shif ting operation will be disabled.
● When selecting the shift position, make sure that the shift posi-
tion has been changed to the desired position by checking the
shift position indicator provi ded on the instrument cluster.
● The shift position cannot be changed from P to B directly.

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. 247) 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 another 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.
In addition, if an attempt is made to change the shift position by moving the
shift lever 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 an attempt is made to change the shift position from P to another
position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B by moving the shift lever.
• When an attempt is made to change the shift position from P to another position by moving the shift lever while the charging cable is connected
to the vehicle.
