Fuel cell systemMaintaining the Fuel cell System
Indicator to Eco area on the
multi-information display can
extend your driving range.
( P.103, 108)
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration.
Mild acceleration and decelera-
tion can help curb wasteful fuel
consumption.
If the brakes are operated gently
and in a timely manner, a
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to decreased fuel economy. Check
traffic reports before leaving and
avoid delays as much as possi-
ble. When driving in a con-
gested traffic situations, gently
release the brake pedal to allow
the vehicle to move forward
slightly while avoiding overuse
of the accelerator pedal. Doing
so can help control excessive
fuel consumption.
Similar to an electric vehicle, a
fuel cell electric vehicle uses the
most fuel in high output driving
such as driving on a steep uphill
or at high speeds. Moderate the
vehicle speed and maintain a
steady speed.
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. (
P.320)
 Use the air conditioning only
when necessary. Doing so
Fuel cell electric vehi-
cle driving tips
To maximize fuel economy
and range, pay attention to
the following:
Use of Fuel cell System
Indicator
Accelerator pedal/brake
pedal operation
When braking
Delays
Driving with high power
output
Using Eco drive mode
Air conditioning

922-1. Fuel cell electric vehicle

can help reduce excessive
fuel consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing
so will help to reduce the bur-
den on the air conditioning
system and reduce fuel con-
sumption as well.
In winter: Avoid excess heat-
ing. Use the seat heater (if
equipped) or steering heater
(if equipped) to minimize the
need for cabin heating
(P.351).
 Using eco air conditioning
mode, this helps curb fuel
consumption even with the air
conditioning system turned
on. ( P.334, 341)
Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to reduced fuel economy. Install-
ing a large roof rack will also reduce fuel economy.

■Instrument cluster brightness
adjustment
The instrument cluster brightness
levels when the tail lights are on and
off can be adjusted individually.
However, when the surroundings
are bright (daytime, etc.), turning on
the tail lights will not chan ge the
instrument cluster brightness.
■Fuel gauge
Displays the quantity of fuel
remaining in the tank
■Driving range
 Displays the possible driving
distance computed from the
fuel consumption studied from
the driving history and the
current remaining amount of
fuel.
 When the air conditioning sys-
tem is operating, is dis-
played below the driving
range and this will be the driv-
ing range with the air condi- tioning system on is
displayed.
■When the low fuel level warning
light turns on
The low fuel level warning light turns
on ( P.460) when the fuel gets low.
In that case, refuel the vehicle.
■Possible Drivi ng Distance
●The actual possible driving dis-
tance may differ as fuel consump-
tion changes, depending on
driving environment (weather, traf-
fic, etc.) and conditions (sudden
acceleration, air conditioning,
etc.).
●The driving range may shorten
even when not driving due to
power consumption by the sys-
tem.
●The possible driving distance will
be displayed as “--- miles (--- km)”
in the following cases:
• When the remaining fuel is being calculated (short time).
• When the remaining fuel total
reaches “E”.
• When a malfunction occurs where the possible driving distance can-
not be calculated.

Trip meter A/Trip meter B
Displays the distan ce the vehicle

can be used to record and display
different distances independently.
■Changing the display
Each time the “ODO/TRIP”
switch is pressed, the displayed
item will be changed. When the
trip meter is displayed, pressing
and holding the switch will reset
the trip meter. The brightness of the instrument
panel lights can be adjusted.
