Continued
Driving
Vehicle Stability Assist ® (VSA ® ), aka Electronic
Stability Control (ESC), System VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.
When VSA ® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system. You will also see
the indicator blink.
■ VSA ® Operation 1 Vehicle Stability Assist ® (VSA ® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Plug-In Hybr id dealer immediately.
The indicators for the Vehicle Stability Assist ® (VSA ® )
System, Vehicle Stability Assist ® (VSA ® ) OFF, low tire
Pressure/TPMS and Collision Mitigation Braking
System TM
(CMBS TM
) may come on along with a
message in the driver information interface after
reconnecting the 12-volt battery. Drive a short
distance at more than 12 mph (20 km/h). The
indicator should go off. If it does not, have your
vehicle checked by an aut horized Honda Clarity Plug-
In Hybrid dealer.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and alwa ys leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.VSA ® System

428 uu When Driving u Tire Pressure Monitoring System (TPMS)
Driving Tire Pressure Monitoring System (TPMS) Instead of directly measuring the pressu re 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 pressu re in all four tires.2 Checking Tires P. 501
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. 501
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.
• Tire chains are used.
The low tire pressure/TPMS indicator may come on
under the following conditions:
• There is a heavier and uneve n load on the tires than
the condition at calibration.
• Tire chains are used.19 CLARITY PHEV-31TRW6100.book 428 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

440 uu Braking u Anti-lock Brake System (ABS)
Driving Anti-lock Brake System (ABS) Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distributi on (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump 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. Depress the brake pedal
and keep holding the pedal firmly down. On dry pavement, you will need to press
on the brake pedal very hard before the AB S activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, 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 wi ll not be operating. Have
your vehicle checked by an authorized 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 lo ckup 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 tire 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 the
vehicle 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.19 CLARITY PHEV-31TRW6100.book 440 ページ ２０１８年１０月２５日　木曜日　午後２時２９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. 506
• 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. 428
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.19 CLARITY PHEV-31TRW6100.book 501 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

Maintenance
The tire identification number (TIN) is a group of numbers and letters that look like
the example in the side column. TIN is located on the sidewall of the tire.
Cold Tire Pressure – The tire air pressure when the vehicle has been parked for at
least three hours or driven less than 1 mile (1.6 km).
Load Rating – Means the maximum load that a ti re is rated to carry for a given
inflation pressure.
Maximum Inflation Pressure – The maximum tire air pressure that the tire can
hold.
Maximum Load Rating – Means the load rating for a tire at the maximum
permissible inflation pr essure for that tire.
Recommended Inflation Pressure – The cold tire inflat ion pressure recommended
by the manufacturer.
Treadwear Indicators (TWI) – Means the projections wi thin the principal grooves
designed to give a visual indication of the degrees of wear of the tread.■ Tire Identification Number (TIN)

507uu Checking and Maintaining Tires u Tire and Wheel Replacement
Maintenance
Tire and Wheel Replacement Replace your tires with radials of the sa me size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist ® (VSA ® ) system to work incorrectly.
It is best to replace all four tires at the same time. If that isn’t possible, replace the
front or rear tires in pairs.
Make sure that the wheel’s specificati ons match those of the original wheels. 1 Tire and Wheel Replacement

WARNING Installing improper tires on your vehicle can
affect handling and stability. This can cause
a crash in which you can be seriously hurt or
killed.
Always use the size and type of tires
recommended in this owner’s manual.19 CLARITY PHEV-31TRW6100.book 507 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

509uu Checking and Maintaining Tires u Winter Tires
Maintenance
Winter Tires If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain sufficient distance be tween vehicles when
driving.
Be particularly careful wh en operating the steering wheel or brakes to prevent
skidding.
Use tire chains, snow tires, or all season ti res when necessary or according to the law.
When mounting, refer to the following points.
For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.
For tire chains:
• Install them on the front tires only.
• Because your vehicle has limited tire clea rance, we strongly recommend using the
chains listed below:
• Follow the chain manufactur er’s instruction when in stalling. Mount them as
tightly as you can.
• Check that the chains do not touc h the brake lines or suspension.
• Drive slowly.Cable-type: SCC Radial Chain SC1040 1 Winter Tires
NOTICE
Traction devices that are th e wrong size or improperly
installed can damage your vehicle’s brake lines,
suspension, body, and wheels. Stop driving if they are
hitting any part of the vehicle.
When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact an
authorized Honda Clarity Plug-In Hybrid dealer.3
WARNING Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.
Follow all instruction s in this owner’s
manual regarding the selection and use of
tire chains.19 CLARITY PHEV-31TRW6100.book 509 ページ ２０１８年１０月２５日　木曜日　午後２時２９分
