WARNING
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing forward or backward, always
depress the brake pedal and
securely apply the parking
brake as needed.
■When the vehicle is parked
●Do not leave glasses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also caus e a short cir-
cuit in the vehicle’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the seat is adjusted,
causing a fire.
●Do not attach adhesive discs to
the windshield or windows. Do
not place containers such as air
fresheners on the instrument
panel or dashboard. Adhesive
discs or containers may act as
lenses, causing a fire in the
vehicle.
●Do not leave a door or window
open if the curved glass is
coated with a metallized film
such as a silver-colored one.
Reflected sunlight may cause
the glass to act a s a lens, caus-
ing a fire.
●Always apply the parking brake,
shift the shift position to P, stop
the fuel cell system and lock the
vehicle.
Do not leave the vehicle unat-
tended while the “READY” indi-
cator is illuminated.
If the vehicle is parked with the
shift position in P but the park-
ing brake is not set, the vehicle
may start to move, possibly
leading to an accident.
■When taking a nap in the vehi-
cle
Always turn the fuel cell system
off. Otherwise, if you accidentally
move the shift lever or depress
the accelerator pedal, causing the
vehicle to unintentionally move,
which can lead to an accident,
resulting in death o r serious injury.
■When braking
●When the brakes are wet, drive
more cautiously.
Braking distance increases
when the brakes are wet, and
this may cause one side of the
vehicle to brake d ifferently than
the other side. Also, the parking
brake may not securely hold the
vehicle.
●If the electronically controlled
brake system does not operate,
do not follow other vehicles
closely and avoid hills or sharp
turns that require braking.
In this case, braking is still pos-
sible, but the brake pedal
should be depressed more
firmly than usual. Also, the brak-
ing distance will increase. Have
your brakes fixed immediately.

■Stopping the fuel cell system in
cold temperatures
●When the power switch is pressed
and the fuel cell system is stopped
during cold temperatures, the time
for water purge from the tailpipe
may be longer than usual to pre-
vent liquid in the fuel cell stack
from freezing.
●If the “FCV System Purge in Prog-
ress Purge will St op Automati-
cally” is displayed in the multi-
information display, however it is
no problem to exit the vehicle.
●The water purge time may also be
long if the system is stopped
before fuel cell system warm-up is
completed.
●It is normal to hear hissing and
other sounds during purge.
(  P. 7 7 )
●It is not a problem to do refueling
operations while the system is
purging.
The purging process is carried out
automatically afte r several min-
utes and a white mist may be
emitted, however this is not a mal-
function.
■Parking the vehic le during cold
weather
●Water may automatically purge
from the tailpipe, even when the
fuel cell system is off, in order to
prevent liquid in the fuel cell stack,
hydrogen pipelines, etc., from
freezing. Also, water vapor may
be purged, but this is not malfunc-
tion.
●It is normal to hear hissing and
other sounds during purge.

■Notes on fueling
●Fueling will not be possible if the
pressure inside the vehicle’s
hydrogen tanks is higher than the
supply pressure of the hydrogen
station. If the hydrogen tanks are
more than half full, the vehicle will
be unable to fuel at a H35 dis-
penser. A hydrogen station with a
H70 dispenser (supply pressure of
10150 psi) [70 MPa, 714 kgf/cm
2,
700 bar] is necessary to com-
pletely fill hydrogen tanks.
●If the fueling cannot be completed
due to trouble with the station
equipment, call the number indi-
cated on the equipment.

Fuel with compressed
hydrogen gas only at hydro-
gen stations.
Fuel at hydrogen stations
