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 between 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 tires 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 installing. 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
1Winter 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.
3WARNING
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 instructions in this owner’s 
manual regarding the selection and use of 
tire chains.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the 
vehicle towed. If the tire only has a smal l puncture, from a nail for instance, you can 
use the temporary tire repair kit so that  you can drive to the nearest service station 
for a more permanent repair.
If a tire goes flat while driving, grasp  the steering wheel firmly, and brake gradually 
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface and apply the parking 
brake.
2. Change the gear position to 
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF 
(LOCK).
1 Temporarily Repairing a Flat Tire
The kit should not be used in  the following situations. 
Instead, contact an authorized Honda Clarity Plug-In 
Hybrid dealer or roadside  assistance to have the 
vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.
•The puncture or cut is larger than 3/16 inch (4 mm).
•The tire side wall is da maged or the puncture is 
outside the contact area.
•Damage has been caused by  driving with the tire 
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or  screw that punctured the 
tire. If you remove it from  the tire, you may not be 
able to repair the puncture using the kit.
When the puncture is:Kit Use
Smaller than 3/16 inch  (4 mm)Yes

uuPower System Won’t StartuEmergency Power System Off
Handling the Unexpected
Emergency Power System Off
The POWER  button may be used to turn the pow er system off due to an emergency 
situation even while driving. If you must turn the power system off, do either of the 
following operations:
• Press and hold the  POWER button for about two seconds.
• Firmly press the  POWER button three times.
The steering wheel will not lock. However,  because turning off the power system 
disables the power assist the power syst em provides to the steering and braking 
systems, it will require significantly more  physical effort and time to steer and slow 
the vehicle. Use both feet on the brake pe dal to slow down the vehicle and stop 
immediately in a safe place.
The gear position auto matically changes to 
(P after the vehicle comes to a complete 
stop. Then, the power mode  changes to VEHICLE OFF.
1Emergency Power System Off
Do not press the button while driving unless it is 
absolutely necessary for the power system to be 
turned off.

uuIndicator, Coming On/Blinking uIf the Electric Power Steering (EPS) System Indicator Comes On
Handling the Unexpected
If the Electric Power Steeri ng (EPS) System Indicator 
Comes On
■Reasons for the indicator to come on
• Comes on when there is a problem with the EPS system.
• If you depress the accelerator peda l repeatedly to increase the motor 
speed while the motor is idling,  the indicator comes on, and 
sometimes the steering wheel becomes harder to operate.
• Comes on when the EPS steering angle center point memory is lost. 
This could be due to a number of problems including: battery 
disconnection, main fuse blow, low battery causing the reset of the 
EPS system, wire damage to EPS ha rness. Vehicle Stability Assist 
(VSA ®), VSA ® OFF, Collision Mitigation Braking System
TM (CMBSTM), 
and low tire pressure/TPMS indicato rs come on along with a message 
in the driver information interface.
■What to do when th e indicator comes on
• Stop the vehicle in a safe place,  turn off the power system, and turn 
on the power system again.
If the indicator re-appears and stay s on, immediately have your vehicle 
inspected by an authorized Honda Clarity Plug-In Hybrid dealer.
• If VSA ® indicator, VSA ® OFF indicator, CMBS
TM indicator, and low tire 
pressure/TPMS indicator come on al ong with a message in the driver 
information interface, you need to  calibrate the VSA and EPS systems.
Drive a short distance at more than  12 mph (20 km/h) to calibrate the 
VSA and EPS systems.
If the indicators come on and stay on, park your vehicle in a safe 
place, turn off and turn on the po wer system, then repeat the above 
operation.
If the indicators still come on and stay on, immediately have your 
vehicle inspected by an authorized  Honda Clarity Plug-In Hybrid dealer.
