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.
Doing so may cause an accident resulting in death or serious in jury.
■ Stopping the fuel cell system in an emergency
If you want to stop the fuel cell system in an emergency while driving the
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,
such as the switch sticking slightly, there may be a malfunctio n. Contact
your Toyota dealer immediately.

The following modes can be selected to suit driving conditions.
■Eco drive mode/Power mode
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.
is displayed on the air conditioning screen and the system
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.
■Br mode
Suitable for driving that requires
strong regenerative braking,
such as down-hill driving, etc.
To select Br mode, shift the shift
lever down. ( P. 193)
The Br mode indicator will illumi-
nate on the meter.
To return to normal driving mode, depress the accelerator pedal or
select the D position again with the shift lever.

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.

Washer/wiper dual oper-
ation
Pulling the lever operates the
wipers and washer.
Wipers will automatically operate a
couple of times after the washer
squirts.
■ The windshield wipers and washers can be operated when
The power switch is in ON mode.
■ Effects of vehicle speed on wiper operation
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor
●If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that “AUTO” mo de is acti-
vated.
● If the temperature of the raindrop sensor is 194 F (90 C) or higher, or 5 F
(-15 C) or lower, automatic operation may not occur. In this case, o perate
the wipers in any mode other than “AUTO” mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is wash er fluid in the
windshield washer fluid reservoir.
● The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs, etc.,
are present on the windshield.
WARNING
■Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take car e that your
fingers, etc., do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. This
may lead to an accident, resulting in death or serious injury.

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current veh icle-
to-vehicle following distance, and operates to maintain a suita ble fol-
lowing distance from the vehicle ahead. The desired vehicle-to- vehi-
cle distance can also be set by operating the vehicle-to-vehicl e
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration crui sing and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle s peed is
necessary, the system applies the brakes (the stop lights will come on at
this time).
The system will respond to changes in the speed of the vehicle ahead in
order to maintain the vehicle-to-vehicle distance set by the dr iver.
Approach warning warns you when the system cannot decelerate su ffi-
ciently to prevent your vehicle fr om closing in on the vehicle ahead.
When the turn signal lever is operated and your vehicle moves to a left
lane while driving at 50 mph (80 km/h) or more, the vehicle wil l quickly
accelerate to help to overtake a passing vehicle.
