◆Using Eco drive mode
Using Eco drive mode (P. 181) 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. 2 5 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. 266).
● 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.

■When starting off on an uphill
The hill-start assist control will activate. ( P. 231)
■ For fuel-efficient driving
Keep in mind that fuel cell vehicles are similar to conventiona l vehicles, and it
is necessary to refrain from activities such as sudden acceleration. ( P. 94)
■ Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
● Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
● Refrain from high speeds when driving on an expressway in the r ain,
because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properl y.
■ Restraining the fuel cell system output (Brake Override System)
● When the accelerator and brake pedals are depressed at the same time, the
fuel cell system output may be restrained.
● A warning message is displayed on the multi-information display while the
system is operating. If a warning message is shown on the multi -information
display, read the message and follow the instructions.
■ Restraining sudden start (Drive-Start Control)
● When the following unusual operation is performed, the fuel cel l system out-
put may be restrained.
• When the shift lever is shifted from R to D, D to R, N to R, P to D, or P to
R with the accelerator pedal depressed, a warning message appea rs on
the multi-information display. If a warning message is shown on the multi-
information display, read the message and follow the instructio ns.
• When the accelerator pedal is depressed too while the vehicle is in
reverse.
● While Drive-Start Control is being activated, your vehicle may have trou-
ble escaping from the mud or fresh snow. In such case, deactiva te TRAC
(  P. 232) to cancel Drive-Start Control so that the vehicle may b ecome
able to escape from the mud or fresh snow.

1625-1. Before driving
MIRAI_OM_USA_OM62025U
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
● Do not drive in excess of the speed limit. Even if the legal sp eed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicl e has high-
speed capability tires. Driving over 85 mph (140 km/h) may resu lt in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed c apability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippa ge and
reduce your ability to control the vehicle.
● Sudden acceleration or regenerative braking due to shifting cou ld cause
the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads m ay prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
■ When changing the shift position
● Do not let the vehicle roll backward while a forward driving position is
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift position to P while the vehicle is movin g.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Do not shift the shift position to R while the vehicle is movin g forward.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Do not shift the shift position to a driving position while the vehicle is mov-
ing backward.
Doing so can damage the transmission and may result in a loss o f vehicle
control.
● Shifting the shift position to N while the vehicle is moving wi ll disengage
the fuel cell system. Regenerative braking is not available with the fuel cell
system disengaged.
● Be careful not to shift the shift position with the accelerator pedal
depressed. Shifting the shift position to any position other th an P or N may
lead to unexpected rapid acceleration of the vehicle that may c ause an
accident and result in death or serious injury.
After shifting the shift position, make sure to check the current shift posi-
tion using the shift position indicator. ( P. 179)

Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize
lane markers causing the lane departure warning function to ope rate incor-
rectly. However, this does not indicate a malfunction.
● When there are shadows on the road running parallel with lane m arkers, or
if a shadow covers the lane markers
● When driving through an area with no lane markers, such as a to ll booth, a
crossing or before a ticket checkpoint
● When the lane markers are broken, Botts’ dots (raised pavement markers)
or stones
● When lane markers are obscured or partially obscured by sand, dirt, etc.
● When driving on a road surface that is wet due to rain, previou s rainfall,
standing water, etc.
● When the lane markers are yellow (These may be more difficult for the sys-
tem to recognize compared to white markers.)
● When the lane markers are on a curb, etc.
● When driving on a particularly bright road surface, such as con crete
● When driving on a road surface that is bright due to reflected light
● When driving in a location where the light level changes rapidl y, such as the
entrance to or exit from a tunnel
● When sunlight or the headlights of oncoming vehicles are shinin g directly
into the camera lens
● When driving on roads that are branching or merging
● When driving on winding roads or roads that are uneven
● When driving on rough or unpaved roads
● When driving on a sharp curve
● When lane markers are extremely narrow or extremely wide
● When the vehicle leans to one side an unusual amount due to a h eavy load
or improper tire inflation pressure
● When the following distance between your vehicle and the vehicl e ahead is
extremely short
● When the vehicle experiences strong up-and-down motion such as when
driving on an extremely rough road or on a seam in the pavement
● When headlight brightness at nighttime is reduced due to dirt on the lenses,
or when the headlights are misaligned
■ When changing the tires

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (suc h as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or s lick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, espe cially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC may not operate effectively when
Directional control and power may not be achievable while drivi ng on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and p ower may be
lost.
■ Hill- start assist control does not operate effectively when
● Do not overly rely on the hill-start assist control. The hill-s tart assist control
may not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not inte nded to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the TRAC, VSC and/or ABS is activated
The slip indicator flashes. Always drive carefully. Reckless dr iving may
cause an accident. Exercise particular care when the indicator flashes.
■ When the TRAC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stabilit y and driving
force, do not turn the TRAC/VSC systems off unless necessary.
