Before driving
■Cleaning the mirror surface
If the mirror surface is dirty, the
image on the display may be dif-
ficult to see.
Clean the mirror surface gently
using a soft dry cloth.
■Cleaning the camera
If the camera lens is dirty or cov-
ered with foreign matter, such as
water droplets, snow, mud, etc.,
the displayed image may not be
clear. In this case, rinse the
camera lens with a large quan-
tity of water and then wipe it

ened with water.
Dirt on the camera lens can be
cleaned by operating the dedi-
cated camera cleaning washer.

■Camera cleaning with washer
fluid
●It may become difficult to see the
rear view of the vehicle due to the
washer fluid which is sprayed
when washing the camera, so
drive while take heed of the sur-
rounding conditions.
●If washer fluid remains on the
camera lens surface after washing
the camera, it may be difficult to
see the rear view of the vehicle
due to the height a nd slope of the
head lamps on the vehicle follow-
ing at night. In that case, change
to optical mirror mode.
●There are cases where even
when the camera is washed it will
not be completed cleaned due to
the dirt. In such cases, rinse off
the camera with large amounts of
water and wipe off the water drop-
lets with soft cloth dampened with
water.
●Reflective items, such as water,
snow, etc., which are attached in
the vicinity of the camera cannot
be washed as the camera clean-
ing sprays washer fluid to the
camera lens.
WARNING
■To prevent causes of fire
If the driver continues using the
Digital Rearview Mirror while
smoke or odor comes from the
mirror, it may res ult in fire. Stop

Observe the following precautions
to reduce the risk of accidents.
Failure to do so m ay result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the specified size.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
Observe the following precautions

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.398)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE

the right-hand side of the trunk.
Remove the luggage mat: P. 3 5 2
■Before recharging
When recharging, the 12-volt bat-
tery produces hydrogen gas which
is flammable and explosive. There-
fore, observe the following precau-
tions before recharging:
●If recharging with the 12-volt bat-
tery installed on the vehicle, be
sure to disconnect the ground
cable.
●Make sure the charger is off when
connecting and disconnecting the
charger cables to the 12-volt bat-
tery.
■After recharging/reconnecting
the 12-volt battery
●Unlocking the doors using the
smart key system may not be pos-
sible immediately after reconnect-
ing the 12-volt battery. If this
happens, use the wireless remote
control or the mechanical key to
lock/unlock the doors.
●Start the fuel cell system with the
power switch in ACC. The fuel cell
system may not start with the
power switch turned off. However,
the fuel cell system will operate
normally from the second attempt.
WARNING
■When adding washer fluid
Do not add washer fluid when the
fuel cell system is hot or operating
as washer fluid contains alcohol
and may catch fire if spilled on the
fuel cell system, etc.
NOTICE
■Do not use any fluid other
than washer fluid
Do not use soapy water or anti-
freeze instead of washer fluid.
Doing so may cause streaking on
the vehicle’s painted surfaces, as
well as damaging the pump lead-
ing to problems of the washer
fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as
necessary.
Refer to the freezing tempera-
tures listed on the label of the
washer fluid bottle.
