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.

Power restriction indicator
Blue: The fuel cell system output power is restricted, because the
coolant temperature is low.
Amber: The fuel cell system output power is restricted, because the
coolant temperature is high.
Outside temperature
Displays the outside temperature within the range of -40°F (-40 °C)
to 122°F (50°C).
Low outside temperature indicator flashes when the ambient tem-
perature is 37°F (3°C) or lower.
Driving range distance
Displays the estimated maximum distance that can be driven with
the quantity of fuel remaining. • Displays the possible driving d istance computed from the fuel
consumption studied f rom the driving history and the current
remaining amount of fuel. The ac tual possible driving distance
may differ as fuel consumpti on changes, depending on driving
environment (weather, traffic, etc.) and conditions (sudden acc el-
eration, air conditioning, etc.).
• When only a small amount of fuel is added to the hydrogen tanks, the display may not be updated.
Speedometer
Displays the vehicle speed.
Odometer and trip meter
Odometer:
Displays the total distance the vehicle has been driven.
Trip meter:
Displays the distance the vehicl e has been driven since the met er
was last reset.
Trip meters “A” and “B” can be used to record and display diffe rent
distances independently.
Distance after start:
Displays the distance driven afte r the fuel cell system was started.
Blank:
A blank is displayed.
