Gauges
Gauges include the speedometer, fuel gauge,  POWER/CHARGE  gauge, high 
voltage battery charge level gauge, and related indicators. They are displayed when 
the power mode is in ON.
Displays your driving speed in mph or km/h.
Displays the approximate amount  of fuel left in the fuel tank.
Shows the estimated distance you can travel 
on the remaining power and fuel. This 
estimate is based on the fuel economy and 
energy consumption of your previous trips 
and the remaining high voltage battery charge 
level.

NOTICE
You should refuel when  the needle approaches  .
Running out of fuel can cause  the engine to misfire, 
damaging the cata lytic converter.
The actual amount of remain ing fuel may differ from

■Electric motor
The degree to which the electric motor is be ing powered is displayed by the readings 
on the  POWER  side.
When you depress the accelerator pedal, th e white needle on the gauge moves. The 
curved blue line on the gauge shows the range within which only the electric motor 
provides propulsion to the wheels. The length of this line varies depending on the 
drive mode and the remaining power of th e High Voltage battery. When the white 
needle exceeds the curved blue  line, the engine starts and the curved blue line turns 
white.
■Battery charge in progress
The degree to which the High Voltage battery is being charged is displayed by the 
readings on the  CHARGE side when coasting or during deceleration.
■POWER/CHARGE Gauge
1Electric motor
The power output of the elec tric motor is restricted 
when the high voltage battery  charge level is running 
low (one segment on the gauge).
If you accelerate  aggressively, the engine may start 
even though the white needle has not exceeded the 
curved blue line.

■High Voltage Battery Charge Level Gauge1High Voltage Battery Charge Level Gauge
When the number of bars displayed on the High 
Voltage Battery Charge Level Gauge becomes one, 
assist by the high-voltage  battery is limited and the 
vehicle output is lowered.
The high voltage battery ch arge level may decrease 
under the following conditions:
•When the 12-volt battery has been replaced.•When the 12-volt battery has been disconnected.
•When the high voltage battery control system 
corrects its reading.
The charge level readi ng will be corrected 
automatically while driving.
Changes in the temperature of the high voltage 
battery can increase or  decrease the battery’s 
charging capacity. If temp erature changes cause the 
battery’s capacity to  change, the number of 
indicators in the battery ch arge level gauge may also 
change, even if the amount of charge remains the 
same.

Low Smart Entry Remo te Signal Strength
The vehicle transmits radio waves to loca te the smart entry remote when locking/
unlocking the doors, opening the trunk,  or to activate the power system.
In the following cases, locking/unlocking the doors, opening the trunk, or activating 
the power system may be inhibited or operation may be unstable:
• Strong radio waves are being tra nsmitted by nearby equipment.
• You are carrying the smart entry remote together with telecommunications 
equipment, laptop computers, ce ll phones, or wireless devices.
• A metallic object is touching or  covering the smart entry remote.
■Key Number Tag1Key Number Tag
Keep the key number tag separate from the key in a 
safe place outside  of your vehicle.
If you wish to purchase an additional key, contact an 
authorized Honda Clarity  Plug-In Hybrid dealer.
If you lose your key an d you cannot activate the 
power system, contact an  authorized Honda Clarity 
Plug-In Hybrid dealer.
1 Low Smart Entry Remote Signal Strength
Communication between the smart entry remote and 
the vehicle consumes the smart entry remote’s 
battery.
Battery life is  about two years,  but this varies 
depending on regularity of use.
The battery is consumed whenever the smart entry 
remote is receivi ng strong radio wave s. Avoid placing 
it near electrical  appliances such as  televisions and 
personal computers.
