uuBraking uCollision Mitigation Braking SystemTM (CMBSTM)
Driving
Collision Mitigati on Braking SystemTM (CMBSTM)
Can assist you when there is a possibility of your vehicle colliding with a vehicle or a 
pedestrian detected in front of yours. The CMBSTM is designed to alert you when a 
potential collision is determined, as well as to reduce your vehicle speed to help 
minimize collision severity when a collision is deemed unavoidable.
■How the system works
1 Collision Mitigation Braking SystemTM (CMBSTM)
Important Safety Reminder
The CMBS
TM is designed to reduce the severity of an 
unavoidable collision. It do es not prevent a collision 
nor stop the vehicle automati cally. It is still your 
responsibility to  operate the brake  pedal and steering 
wheel appropriately acco rding to the driving 
conditions.
The CMBS
TM may not activate or may not detect a 
vehicle in front of y our vehicle under certain 
conditions: 2 CMBS
TM Conditions and Limitations  P. 432
You can read about handling information for the 
camera equipped with this system. 2 Front Sensor Camera  P. 383
Be careful not to severely  impact the radar sensor 
cover.
1 How the system works
Rapid vibrations on the  steering wheel alert you 
when the your vehicle speed is between 19 and 62 
mph (30 and 100 km/h) with an oncoming vehicle 
detected in front of you.
When the CMBS
TM activates, it  may automatically 
apply the brake. It will be  canceled when your vehicle 
stops or a potential coll ision is not determined.
The radar sensor is 
behind the emblem.
The camera is 
located behind 
the rearview 
mirror.
The system starts monitoring the roadway ah ead when your vehicle speed is about 3 
mph (5 km/h) and there is a vehicle in front of you.
When to use
The CMBSTM activates when:●The speed difference between your vehicle and a vehicle or pedestrian detected 
in front of you becomes about 3 mph (5 km/h) and over with a chance of a 
collision.
●Your vehicle speed is about 62 mph (100 km/h) or less and there is a chance of a 
collision with an oncoming detected vehicle or a pedestrian in front of you.

1Charging
NOTICE
Do not charge the vehicle wi th a vehicle cover on. It 
can cause a malfunction and  damage the vehicle or 
charging components.
The 120 volt charger requires a properly grounded 
and dedicated circuit that is  protected by a 15 amp or 
greater over-curre nt protection device (circuit 
breaker). For more informati on consult an authorized 
Honda Clarity Electric dealer.
We recommend that a GFCI (ground-fault circuit 
interrupter) protected outlet  be used to charge the 
vehicle. Follow the GF CI maker's installation 
instructions, or consult an  electrician if you are not 
sure about installation requirements.
Inspect the charging cable plug and charging 
connector, as well as the vehicle’s charge inlet, 
before use. If the plug or  connector are dirty or 
otherwise contaminated, care fully clean them with a 
dry clean cloth before use.  Do not wipe the metal 
part of the inlet and the ch arging connector. Also, if 
you are unable to clean the plug or connector, if the 
inlet is dirty, or if any ar e damaged or corroded, take 
the charging cable and vehi cle to an authorized 
Honda Clarity Electric de aler for inspection and 
possible repair.
Before using a vehicle char ging cable, inspect the 
cable for damage such as scratches, cracks, or tears. 
If you find any damage, do not use the charging 
cable; instead, take it to an authorized Honda Clarity 
Electric dealer for inspection.

To avoid damage to th e charger, take these 
precautions:
•Do not hit the charging connector components 
with a hard object or drop them on the ground.
•Do not pull, twist, tangle,  drag or step on the 
charging cable.
•Do not use or store near  any sources of heat.

Handling the Unexpected
Emergency Power System Off
The POWER  button may be used to turn the power system off due to an emergency 
situation even while driving. If you must tu rn 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.
1 Emergency Power System Off
Do not press the button while driving unless it is 
absolutely necessary for the power system to be 
turned off.
