detected.
The alarm is triggered in the following situations when the alarm is
set:
●A locked door or trunk is unlocked or opened in any way other than
using the entry function, wireless remote control or mechanical key.
(The doors will lock again automatically.)
● The hood is opened.
Close the doors, trunk and hood,
and lock all the doors. The system
will be set automatically after 30
seconds.

There is an air intake vent beside
the rear left seat for the purpose
of cooling the traction battery. If
the air intake vent is blocked, it
could lead to a reduction in trac-
tion battery output.
■ If a warning light comes on, a warn ing message is displayed, or the 12-
volt battery connection is disconnected
The fuel cell system may not be able to restart.
If the “READY” indicator does not come on, even when the start pro\
cedure is
repeated, contact your Toyota dealer.
■ If “Hydrogen Leakage Detected Visit Your Dealer” is displayed on the
multi-information display
A small amount of hydrogen gas may be leaking. Have the vehicle inspected
immediately at the nearest Toyota dealer.
■ If “FC System Shutdown due to Hydrogen Leakage Stop Your Vehicle in
a Safe Place and Contact Your Dealer ” is displayed on the multi-informa-
tion display
● Hydrogen gas may be leaking.
When hydrogen gas is leaking or some other malfunction is detected:
→P. 9 0
● The air conditioning system will shut off automatically.
■ Running out of fuel
When the vehicle has run out of fuel and the fuel cell system cannot be
started, refuel the vehicle until the low fuel level warning light ( →P. 371) turns
off before trying to restart. It may not be able to restart if the refueled amount
is too low (less than about 2.7 lb. [1.2 kg]).

Hydrogen Gas Characteristics
●Hydrogen gas ignites more easily than gasoline. However, it is lighter than
air and disperses quickly. So even if hydrogen were to leak from the system,
it would quickly dilute until it is no longer flammable.
● As with gasoline and natural gas, hydrogen gas is not dangerous if it is han-
dled properly. Thoroughly read and understand the characteristics shown in
the table below.

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. 1 1 0 )
◆Accelerator pedal/brake pedal operation
Drive the vehicle smoothly. Avoid abrupt acceleration and decelera-
tion.
Mild acceleration and deceleration can help curb wasteful fuel con-
sumption.
◆When braking
Make sure to depress the brake gently and allow for a long stopping
distance. This enables collection of more electrical energy gener-
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 caught
in a traffic jam, gently release the brake pedal to allow the vehicle 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 most fuel in
high output driving such as driv ing on a steep uphill or at high
speeds. Moderate the vehicle speed and maintain a steady speed.
To maximize fuel economy and range, pay attention to the fol-
lowing:
