WARNING
■Traction battery
● Never resell, transfer, or modify the traction battery. To prev ent accidents,
traction batteries that have been removed from disposed vehicle are col-
lected through Toyota dealers. Do not dispose of the traction battery your-
self.
If the traction battery is not properly collected, the following may occur,
resulting in death or serious injury:
• The traction battery may be illegally disposed or dumped, and it is haz-
ardous to the environment. Additionally, someone may touch a high-volt-
age part, resulting in an electric shock.
• The traction battery is intended to be used exclusively with your fuel cell vehicle. If the traction battery is used outside of your vehicl e or modified
in any way, accidents, such as electric shock, heat generation, smoke
generation, ignition, explosion and electrolyte leakage may occ ur.
In particular, reselling or transferring the traction battery exposes the
receiving party to risks of accidents as they may not be aware of these
dangers. Make sure to inform them of the contents of this Owner ’s Man-
ual.
● If your vehicle is disposed without the traction battery having been
removed, there is a danger of serious electric shock in case hi gh-voltage
parts, cables, or their connectors are touched. When disposing of your
vehicle, the traction battery must be disposed by your Toyota d ealer, or a
qualified service shop. If the traction battery is not disposed of properly, it
may cause electric shock that can result in death or serious in jury.
NOTICE
■Traction battery air intake vent
● If the traction battery output decreases due to the entry of dust or debris,
foreign material, a warning message is shown on the multi-infor mation dis-
play. Have the vehicle inspected at your Toyota dealer.
● Do not place objects where the air intake vent will be obstruct ed. This may
lead to a reduction in traction battery power output and damage .
● Clean the air intake vent regularly to prevent clogging.
● Do not allow water or objects to enter the air intake vent, as this may dam-
age the traction battery.
■ Traction Battery
Do not spill a large amount of water near the traction battery in the vehicle.
If water spills onto the traction battery, have the vehicle ins pected at your
Toyota dealer.

Advice for driving fuel cell vehicles
◆Fuel cell system indicator usage
Maintaining the fuel cell system indicator to Eco area on the
multi-information display can extend your driving range. (P. 120)
◆Accelerator pedal/brake pedal operation
Drive the vehicle smoothly. Avo id abrupt acceleration and decel era-
tion.
Mild acceleration and decelerati on can help curb wasteful fuel con-
sumption.
◆When braking
Make sure to depress the brake gently and allow for a long stop ping
distance. This enables collectio n of more electrical energy gen er-
ated during deceleration.
◆Heavy traffic
Repeated acceleration and deceleration as well as long stops at
traffic lights, will decrease fuel economy. Check traffic reports
ahead of time and avoid traffic jams as much as possible. If ca ught
in a traffic jam, gently release the brake pedal to allow the v ehicle to
move forward slowly while avoiding overuse of the accelerator
pedal to help curb wasteful fuel consumption.
◆Driving with high power output
Similar to an electric vehicle, a fuel cell vehicle uses the mo st fuel in
high output driving such as driving on a steep uphill or at hig h
speeds. Moderate the vehicle speed and maintain a steady speed.
To maximize fuel economy and ra nge, pay attention to the fol-
lowing:

◆Using Eco drive mode
Using Eco drive mode (P. 195) makes torque generation less
aggressive than normal when stepping on the accelerator pedal,
leading to improvement in fuel economy.
Also, is displayed on the air conditioning screen, indicating
the switch to ECO HEAT/COOL mode ( P. 3 0 8 ) .
◆Air conditioning system on/off
● Turn off the air conditioning system operation switch except
when necessary to help curb fuel consumption.
In summer: When the ambient temperature is high, use the recircu -
lated air mode. This decreases the load on the air con-
ditioning system.
In winter: Avoid excess heating. Use the seat heater to minimize the need for cabin heating ( P. 316).
● By pushing , ECO HEAT/COOL mode is turned on. This
helps curb fuel consumption even with the air conditioning syst em
turned on.
◆Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Impr oper
tire inflation pressure can cause poor fuel economy.
Additionally, snow tires have mo re rolling friction and their use on
dry roads lead to poor fuel economy. Use tires that are appropr iate
for the season.
◆Luggage
Avoid carrying unnecessary luggage and unload excess weight in
order avoid poor fuel economy. Installing a large roof rack wil l also
reduce fuel economy.

WARNING
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning lights not
come on when you start the fuel cell system, this could mean that these
systems are not available to help protect you in an accident, which could
result in death or serious injury. Have the vehicle inspected by your Toyota
dealer immediately if this occurs.
