425uu When Driving u Tire Pressure Monitoring System (TPMS)
Continued
Driving
Tire Pressure Monitoring System (TPMS) Instead of directly measuring the pressure in each tire, the TPMS on this vehicle
monitors and compares the rolling radius and rotational characteristics of each
wheel and tire while you are driving to determine if one or more tires are
significantly under-inflated. This will caus e the low tire pressure/TPMS indicator to
come on and a message to appear on the driver information interface.
You must start TPMS calibration every time you:
• Adjust the pressure in one or more tires.
• Rotate the tires.
• Replace one or more tires.
Before calibrating the TPMS:
• Set the cold tire pressure in all four tires. 2 Checking Tires P. 499
Make sure:
• The vehicle is at a complete stop.
• The gear position is in ( P
.
• The power mode is in ON.■ TPMS Calibration 1 Tire Pressure Monitoring System (TPMS)
The system does not monitor the tires when driving
at low speed.
Conditions such as low ambient temperature and
altitude change directly a ffect tire pressure and can
trigger the low tire pressure/TPMS indicator to come on.
Tire pressure checked and inflated in:
• Warm weather can beco me under-inflated in
colder weather.
• Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS may not function pr operly if tire type and
size are mixed. Make sure to use the same size and
type of tire.
2 Checking and Maintaining Tires P. 499
The low tire pressure/TPMS indicator may come on
with a delay or may not come on at all when:
• You rapidly accelerate, decelerate, or turn the
steering wheel.
• You drive on snowy or slippery roads.
• Snow chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
• There is a heavier and une ven load on the tires,
such as when towing a trailer, than the condition at
calibration.
• Snow chains are used.18 CLARITY PHEV CSS-31TRW6000.book 425 ページ ２０１７年８月３１日　木曜日　午後２時４９分

429 uu When Driving u LaneWatch TM
Continued
Driving
LaneWatch TM
LaneWatch is an assistance system that al lows you to check the passenger side rear
areas displayed on the audio/information screen when the turn signal is activated to
the passenger’s side. A camera in the pa ssenger side door mi rror monitors these
areas and allows you to check for vehicles, in addition to your visual check and use
of the passenger door mirror. You can also keep the system on for your convenience
while driving. 1 LaneWatch TM
Important Safety Reminder
Like all assistance systems, LaneWatch has
limitations. Over reliance on LaneWatch may result in
a collision.
The LaneWatch func tion can be affect ed by weather,
lighting (including headli ghts and low sun angle),
ambient darkness, camera condition, and loading.
The LaneWatch may not prov ide the intended display
of traffic to the side a nd rear under the following
conditions:
• Your vehicle’s suspension has been altered,
changing the height of the vehicle.
• Your tires are over or under inflated.
• Your tires or wheels are of varied size or
construction.3
WARNING Failure to visually confirm that it is safe to
change lanes before doing so may result in
a crash and serious injury or death.
Do not rely only on LaneWatch while
driving.
Always look in your mi rrors, to either side
of your vehicle, and behind you for other
vehicles before changing lanes.1 2
CameraMove the turn signal
lever to the passenger
side. Press the LaneWatch
button. The passenger side view
display appears on the
audio/information screen.The system activates when you:
The system deactivates when you press
the LaneWatch button again.

437uu Braking u Anti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS) Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribu tion (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pu mp the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ ABS operation
You may hear an operating noise when the ABS is working. Keep holding the pedal
firmly down. On dry pavement, you will ne ed to press on the brake pedal very hard
before the ABS activates. Ho wever, you may feel the ABS activate immediately if you
are trying to stop on snow or ice.
ABS may activate when you depres s the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surf aces, such as potholes , cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.■ ABS 1 Anti-lock Brake System (ABS) NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS will not operating. Have your
vehicle checked by an aut horized Honda Clarity Plug-
In Hybrid dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lockup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
• You are driving on rough or uneven road surfaces,
such as gravel or snow.
• The tires are equipped with snow chains.
The following may be observed with the ABS system:
• Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been turned on and while
vehicle is accelerates.
• Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.18 CLARITY PHEV CSS-31TRW6000.book 437 ページ ２０１７年８月３１日　木曜日　午後２時４９分

Maintenance
Checking and Maintaining Tires Checking Tires To safely operate your vehicle, your tire s must be of the proper type and size, in
good condition with adequate tread, and properly inflated.
■ Inflation guidelines
Properly inflated tires provid e the best combination of hand ling, tread life, and comfort.
Refer to the driver’s doorjamb label or spec ifications page for the specified pressure.
Underinflated tires wear unev enly, adversely affect handli ng and fuel economy, and
are more likely to fail from overheating.
Overinflated tires make your vehicle ride ha rshly, are more pron e to road hazards,
and wear unevenly.
Every day before you drive, look at each of the tires. If one looks lower than the
others, check the pressure with a tire gauge.
At least once a month or before long trips , use a gauge to measure the pressure in
all tires. Even tires in good condition can lose 1–2 psi (10–20 kPa, 0.1–0.2 kgf/cm 2
)
per month.
■ Inspection guidelines
Every time you check inflation, also examine the tires and valve stems.
Look for:
• Bumps or bulges on the side or in the tr ead. Replace the tire if you find any cuts,
splits, or cracks in the side of the tire . Replace it if you see fabric or cord.
• Remove any foreign objects and inspect for air leaks.
• Uneven tread wear. Have an authorized H onda Clarity Plug-In Hybrid dealer check
the wheel alignment.
• Excessive tread wear. 2 Wear Indicators P. 504
• Cracks or other damage around valve stem. 1 Checking Tires
Measure the air pressure when tires are cold. This
means the vehicle has been parked for at least three
hours, or driven less than 1 mile (1.6 km). If
necessary, add or releas e air until the specified
pressure is reached.
If checked when hot, tire pressure can be as much as
4–6 psi (30–40 kPa, 0.3–0.4 kgf/cm 2
) higher than if
checked when cold.
Whenever tire pressure is adjusted, you must
calibrate the TPMS.
2 TPMS Calibration P. 425
Have an authorized Honda Clarity Plug- In Hybrid
dealer check the tires if you feel a consiste nt vibration
while driving. New tires and any that have been
removed and reinstalled sh ould be properly balanced.3
WARNING Using tires that are excessively worn or
improperly inflated can cause a crash in
which you can be seriously hurt or killed.
Follow all instruction s in this owner’s
manual regarding tire inflation and
maintenance.18 CLARITY PHEV CSS-31TRW6000.book 499 ページ ２０１７年８月３１日　木曜日　午後２時４９分
