WARNING
■When starting the fuel cell system
Always start the fuel cell system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the fuel cell syst em under any
circumstances.

vehicle, press and hold the power switch for more than 2 second s, or press
it briefly 3 times or more in succession. ( P. 409)
However, do not touch the power switch while driving except in an emer-
gency. Turning the fuel cell system off while driving will not cause loss of
steering or braking control, however, power assist to the steer ing will be
lost. This will make it more difficult to steer smoothly, so yo u should pull over
and stop the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent 12-volt b attery discharge
Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods if the fuel cell system is off.
■ When starting the fuel cell system
If the fuel cell system becomes difficult to start, have your vehicle checked
by your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual,

and ensure correct shifting
operation.
Release the shift lever after
each shifting operation to allow
it return to the position.When shifting to the D
or R positions, move
the shift lever along the
shift gate.
To shift to the N posi-
tion, slide the shift lever
to the left and hold it.
The shift position will
change to N.
To shift to the Br mode, pull the shift lever to the rear along
the shift gate. Shifting to Br mode is only possible when the
shift position D is selected.
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 that the veh icle
is stationary.
Shift position indicator
When selecting a shift position, make sure that the shift posit ion
has been changed to the desired po sition by checking the shift
position indicator provided on the instrument panel.

Eco drive mode
Suitable for improving the
fuel economy, because the
torque corresponding to the
accelerator pedal depres-
sion amount can be gener-
ated more smoothly than it is
in normal conditions.

goes into ECO HEAT/COOL mode. ( P. 308)
When the “ECO MODE” switch is pressed, the “ECO MODE”
indicator will illuminate on the main display.
To cancel Eco drive mode, press the “ECO MODE” switch again.
At this time, the ECO HE AT/COOL mode is canceled.
Power mode
Use when high levels of response and feeling are desirable, such
as when driving in mountainous regions or when overtaking.
When the “POWER MODE” switch is pressed, the POWER
MODE indicator will illumi nate on the main display.
To cancel power mode, press the “POWER MODE” switch again.

■For the shift positions
●When the power switch is off, the shift position cannot be chan ged.
● When the power switch is in ON mode (the fuel cell system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift position is shifted to D or R and held in that
position.
● When the “READY” indicator is on, the shift position can be cha nged from P
to D, N or R.
● When the “READY” indicator is flashing, the shift position cann ot be
changed from P to another position even if the shift lever is o perated.
Wait until the “READY” indicator changes from a flashing to a s olid light, and
then operate the shift lever again.
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 situa-
tions, a buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happen s, select an
appropriate shift position.
● When attempting to change the shift position from P without dep ressing the
brake pedal, the shift position change is invalidated.
● Situations where the shift position will automatically change t o N:
• When the P position switch is pressed while the vehicle is running.
*1
• 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 an attempt is made to change the shift position from R to Br mode
by moving the shift lever.
*1: Shift position may be changed to P when driving at extremely l ow 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.
■ Br mode
Depending on the condition of the traction battery, Br mode may not be avail-
able.
In that case, a message is displayed on the multi-information d isplay.
■ Sounds when in Br mode

Regenerative Braking
When the shift position is in D, regenerative braking is engage d when the foot
is released from the accelerator pedal.
■ ECO HEAT/COOL mode operation for Eco drive mode
●When the “ECO MODE” switch is pressed, the system switches over to
ECO HEAT/COOL mode. ( P. 311) During the use of Eco drive mode, only
the ECO HEAT/COOL mode can be canceled.
● When it is desired to improve the effectiveness of the air cond itioning sys-
tem, perform the following operations.
• Adjust the temperature settings and airflow mode.
• Press of the air conditioning operation panel ( P. 306) and can-
cel the ECO HEAT/COOL mode, or cancel Eco drive mode.
■ Power mode automatic deactivation
Power mode is automatically deactivated if the power switch is turned off after
driving in power mode.
■ Shifting from P on a slope
When changing to another position from P when parked on a slope in the P
position, vibrations may be felt.
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in regenerative braking may cause the vehicle to spin or
skid, resulting in an accident.
■ For the shift lever
Do not remove the shift lever knob or use anything but a genuin e Toyota
shift lever knob. Also, do not hang anything on the shift lever .
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
■ 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
example, directly before stopping the vehicle), the vehicle may stop sud-
denly when the shift position switches to P, which could lead t o an accident.
