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.

Driving
started the vehicle has not been
driven for a certain amount of time
• While making a left/right turn and
for a few seconds after making a
left/right turn
• While driving on a curve and for a
few seconds after driving on a
curve
• If your vehicle is skidding
• If the front of the vehicle is raised
or lowered
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera
is misaligned
• When driving in a traffic lane sep-
arated by more t han one lane
where oncoming vehicles are driv-
ing while making a right/left turn
• When largely out of place with the opposite facing targeted oncom-
ing vehicle during a right/left turn
• While making a right/left turn, when a pedestrian approaches
from behind or side of your vehicle
●In addition to the above, in some
situations, such as the following,
the emergency steering assist
may not operate.
• When the white (yellow) lane lines are difficult to see, such as when
they are faint, diverging/merging,
or a shadow is cast upon them
• When the lane is wider or nar-
rower than normal
• When there is a light and dark pat- tern on the road surface, such as
due to road repairs
• When the target is too close
• When there is insufficient safe or unobstructed space for the vehicle
to be steered into
• If oncoming vehicle is present
• If VSC function is operating
●In some situations such as the fol-
lowing, sufficien t braking force or
steering force may not be
obtained, preventing the system
from performing properly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, ext remely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces-
sively worn, imprope r tire inflation
pressure, etc.)
• When the vehicle is being driven on a gravel road or other slippery
surface
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right

WARNING
The fuel cell unit compartment
contains many mechanisms and
fluids that may move suddenly,
become hot, or become electri-
cally energized. To avoid death or
serious injury, observe the follow-
ing precautions.
■When working on the fuel cell
unit compartment
●Be careful not to touch the high-
voltage parts or hydrogen-
related parts.
●Make sure that the “READY”
indicator is off.
●Keep hands, clothing and tools
away from the moving fan.
●Be careful not to touch the
motor, inverter, radiator, etc.
right after driving as they may
be hot. Coolant and other fluids
may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the fuel cell unit com-
partment.
ItemsParts and tools●Do not smoke, cause sparks or
expose an open flame to the 12-
volt battery. 12-volt battery
fumes are flammable.
●Be extremely cautious when
working on the 12-volt battery. It
contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid
can harm your hands or eyes
and damage painted surfaces. If
fluid gets on your hands or in
your eyes, flush the affected
area with clean water immedi-
ately.
If you still experience discom-
fort, consult a doctor.
●Never touch, disassemble,
remove or replace the high-volt-
age parts, cables and their con-
nectors. It can cause severe
burns or electric shock that may
result in death or serious injury.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the power switch is off.
With the power switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P. 4 1 1 )
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
motor wear due to dirt in the air.
