2021 HONDA CLARITY PLUG-IN fuel pressure

12
Quick Reference Guide
There are three drive modes: ECON, NORMAL, and SPORT
Regardless of the drive mode that is activated, when the accelerator pedal is depr essed past a certain point, the engine starts . When this
occurs, electrical power generated by the en gine combines with electrical power from the battery to provide greater driving force. If you
select ECON mode, the threshold for the engine to provide additional power is higher than it is when the vehicle operates under either of
the two sources. Note that if the accelerator pedal is depressed past the point at which you feel a click, the engine will star t in the ECON
mode.
To maintain fuel efficiency, keep steady pressure on the accelerator pedal and avoid aggressive acceleration and deceleration.

Driving
Tire Pressure Monitoring System (TPMS) - Required
Federal Explanation
Each tire, including the spare (if provided), should be checked
monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufa cturer on the vehicle placard
or tire inflation pressure label.
(If your vehicle has tires of a diff erent size than the size indicated
on the vehicle placard or tire inflation 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 tires is significantly under-inflated.
Accordingly, when the low tire pressure 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-inf lated tire causes the tire to
overheat and can lead to tire fail ure. Under-inflation also reduces
fuel efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.

Driving
How to Refuel
1. Stop your vehicle with the service station
pump on the left side of the vehicle in the
rear.
2. Put the transmission into
(P.
3. Turn the power system off.
4. Press the fuel fill door release button.
u Please Wait appears for a few seconds
on the driver information interface.
5. When the message changes to Ready, the
fuel fill door automatically opens.
u You can now unscrew the fuel cap and
start refueling.
6. Remove the fuel fill cap slowly. If you hear a
release of air, wait until this stops, then turn
the knob slowly to open the fuel fill cap.
1How to Refuel
This vehicle has a pressurized fuel system.
When the fuel vapor pressure inside the fuel tank is
high, it takes about 10 seconds for the vehicle to vent
the fuel tank. Once the pressure is vented, the driver
information interface changes from Please Wait to
Ready.
If the filler nozzle keeps tu rning off when the tank is
not full, there may be a pr oblem with the pump’s fuel
vapor recovery system. Try fi lling at another pump. If
this does not fix the problem, consult a dealer.
The filler nozzle automatically stops to leave space in
the fuel tank so that fuel do es not overflow as a result
of changes in air temperature.
Do not continue to add fuel after the filler nozzle has
automatically stopped. Addi tional fuel can exceed
the full tank capacity.
3WARNING
Gasoline is highly flammable and explosive.
You can be burned or seriously injured
when handling fuel.
• Stop the engine, and keep heat, sparks,
and flame away.
• Handle fuel only outdoors.
• Wipe up spills immediately.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accord ance with the messages displayed on the
driver information interface.
• Use the recommended vi scosity engine oil.
2Recommended Engine Oil P. 488
•Maintain the specified tire pressure.
• Do not load the vehicle with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test. For more
information on how this test is performed, please visit
