Always keep the radar sensor cover clean.
Never use chemical solvents or polishing powder for
cleaning the sensor cover. Clean it with water or a
mild detergent.
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
If you need the radar sensor to be repaired, or
removed, or the radar se nsor cover is strongly
impacted, turn off the system by pressing the MAIN
button and take your vehicl e to an authorized Honda
Clarity Plug-In Hybrid dealer.
Have your vehicle checked by an authorized Honda
Clarity Plug-In Hybrid deal er if you find any unusual
behavior of the system (e.g., the warning message
appears too frequently).18 CLARITY PHEV CSS-31TRW6000.book 406 ページ ２０１７年８月３１日　木曜日　午後２時４９分

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

message appears, repeat steps 4-6.
• The calibration pr ocess finishes
automatically. 1 TPMS Calibration
• The calibration process requires appr oximately 30
minutes of cumulative dr iving at speeds between
30-65 mph (48-105 km/h).
• During this period, if the power system is turned on
and the vehicle is not moved within 45 seconds, you
may notice the low tire pressure/TPMS indicator
comes on briefly. This is normal and indicates that
the calibration process is not yet complete.
If snow chains are instal led, remove them before
calibrating the TPMS.
If the low tire pressure/TPMS indicator comes on even
when the properly inflated specified regular tires are
installed, have your vehicl e checked by an authorized
Honda Clarity Plug-In Hybrid dealer.
We recommend that the tires be replaced with the
same brand, model, and size as the originals. Ask an
authorized Honda Clarity Pl ug-In Hybrid dealer for
details.

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-

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

507uu 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.18 CLARITY PHEV CSS-31TRW6000.book 507 ページ ２０１７年８月３１日　木曜日　午後２時４９分
