camera equipped with this system. 2 Front Sensor Camera  P. 385
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 Electric dealer.
Have your vehicle checked  by an authorized Honda 
Clarity Electric dealer if  you find any unusual behavior 
of the system (e.g., the wa rning message appears too 
frequently).

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 motor out put and selectively applying the brakes.
When VSA ® activates, you may notice that the 
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 Electric  dealer immediately.
The indicators for the Vehicle Stability Assist ® (VSA ®) 
System, Vehicle Stability Assist ® (VSA ®) OFF, low tire

System
TM (CMBSTM) may come on along with a 
message in the driver information interface after re-
connecting 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 
authorized Honda Clarity Electric 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

uuWhen Driving uTire 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.
2Checking Tires  P. 477
Make sure:
•The vehicle is at a complete stop.
• The gear position is in 
(P.
• The power mode is in ON.
■TPMS Calibration
1Tire 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. 477
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.

You can calibrate the system from the 
customized feature on  the audio/information 
screen.
1. Set the power mode to ON.
2. Select .
3. Select  Settings .
4. Select  Vehicle .
5. Select  TPMS Calibration .
6. Select  Cancel  or Calibrate .
u When the calibration is complete, the 
display returns to the customization 
menu screen.
• If the  Calibration Failed To Start.  
message appears, repeat steps 4-6.
• The calibration process finishes 
automatically.1TPMS Calibration
•The calibration process  requires approximately 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 briefl y. This is normal and 
indicates that the calibr ation process is not yet 
complete.
If tire chains are installed, 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 Electric dealer.
We recommend that the tires be replaced with the 
same brand, model, and size  as the originals. Ask an 
authorized Honda Clarity El ectric dealer for details.

uuWhen Driving uTire Pressure Monitoring System (TPMS) - Required Federal Explanation
Driving
Tire Pressure Monitoring  System (TPMS) - Required 
Federal Explanation
Each tire, including the spare (i f provided), should be checked 
monthly when cold and inflated  to the inflation pressure 
recommended by the vehicle manufacturer on the vehicle placard 
or tire inflation pressure label.
(If your vehicle has tires of a different size than the size indicated 
on the vehicle placard or tire infl ation pressure label, you should 
determine the proper tire inflat ion pressure for those tires.)
As an added safety feature, your  vehicle has been equipped with 
a tire pressure monitoring system  (TPMS) that illuminates a low 
tire pressure telltale 
when one or more of your tire s is significantly under-inflated.
Accordingly, when the low tire pr essure telltale illuminates, you 
should stop and check your tires  as soon as possible, and inflate 
them to the proper pressure.
Driving on a significantly under-in flated tire causes the tire to 
overheat and can lead to tire fail ure. Under-inflation also reduces 
energy efficiency and tire tread life, and may affect  the vehicle’s 
handling and stopping ability.

uuWhen Driving uLaneWatchTM
Driving
LaneWatchTM
LaneWatch is an assistance system that allows you to check the passenger side rear 
areas displayed on the audio/in formation screen when the turn signal is activated to 
the passenger’s side. A camera in the passenger side door mirror 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 LaneWatchTM
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 affected 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 and 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.
3WARNING
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.
