uuCharging uHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges even if the vehicle is not in use. As a
result, if your vehicle is parked for an ex tended period of time, the battery level may
get low. Keeping your vehicle’s battery le vel low can shorten the battery life. To
maintain the battery while the vehicle is not in use, recharge the battery at least
once every three months.
The High Voltage battery life can also be affected by ambient temperature. In
particular, when it is cold outside, the ve hicle’s driving range on electric power can
be reduced, and a longer battery charging ti me is required. In addition, parking in
extremely hot or cold environments can accelerate battery drain.
To help extend the lifespan of the battery, it is recommended that you fully charge
the battery each time prior to driving.
Store the vehicle in a garage to insure that the temperature of the High Voltage
battery does not drop too low.
■Battery Warming System
Designed to prevent the temperature of the battery from dropping when outside
temperatures drop, thereby maintainin g starting and running efficiency.
If the vehicle is plugged in when outside temperatures are low, the battery warming
system will use the power from the charging equipment to maintain the
temperature of the battery until the next time the vehicle is driven.
1 High Voltage Battery
The High Voltage battery dr ains over time, and under
some conditions, drains fast er. When the battery life
is shortened, this cha nges the vehicle’s driving
distance.
Be careful not to let the High Voltage battery drain
too much. If the battery level becomes close to zero,
it will make it impossible to start the engine.
U.S. models
1 Battery Warming System
If the vehicle is left unplug ged in cold temperatures,
the temperature of the ba ttery will drop, possibly
resulting in a loss of running efficiency.
If left for an extended period of time in extremely
cold temperatures, the vehicle may not start. We
recommend that you plug in your vehicle when you
are parking or storing your vehicle in cold
temperatures.Canadian models

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. 486
•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

in good condition. If you become aware of an y abnormality (noise, smell, insufficient
brake fluid, oil residue on the ground, etc .), have your vehicle inspected by an
authorized Honda Clar ity Plug-In Hybrid dealer. (Note, however, that service at an
authorized Honda Clar ity Plug-In Hybrid dealer is not mandatory to keep your
warranties in effect.)
■Daily inspections
Perform inspections before long distance trips, when washing the vehicle, or when
refueling.
■Periodic inspections
• Check the brake fluid level monthly.
2 Brake Fluid P. 496
•Check the tire pressure monthly. Examin e the tread for wear and foreign objects.
2Checking and Maintaining Tires P. 503
•Check the operation of the exterior lights monthly.
2 Replacing Light Bulbs P. 498
•Check the condition of the wiper bl ades at least every six months.
2Checking and Maintaining Wiper Blades P. 500
■Types of Inspection and Maintenance
1Inspection and Maintenance
Maintenance, replacement, or repair of
emissions control devices and systems may be
done by any automotive repair establishment or
individuals using parts that are “certified” to
EPA standards.
According to state and fede ral regulations, failure to
perform maintenance on the maintenance main
items marked with # will not void your emissions
warranties. However, all ma intenance services should
be performed in accordan ce with the intervals
indicated by the driver information interface.
2 Maintenance Service Items P. 481
If you want to perform complex maintenance tasks
that require more skills a nd tools, you can purchase a
subscription to the Service Express website at
www.techinfo.honda.com .
2 Authorized Manuals P. 579
If you want to perform ma intenance yourself, make
sure that you have the necessary tools and skills first.
After performing maintenanc e, update the records in
the separate maintenance booklet.

Safety When Performing Maintenance
Some of the most important safe ty precautions are given here.
However, we cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether you should perform a given
task.
• To reduce the possibility of fire or explos ion, keep cigarettes, sparks, and flames
away from the 12-volt battery, all High Volt age system, and all fuel related parts.
• Never leave rags, towels, or other flammable objects under the hood.
u Heat from the engine and exhaust can ignite them, causing a fire.
• To clean parts, use a co mmercially available degreaser or parts cleaner, not
gasoline.
• Wear eye protection and pr otective clothing when working with the 12-volt
battery or compressed air.
• Engine exhaust contains carbon monoxide, which is poisonous and can kill you.
u Only operate the engine if th ere is sufficient ventilation.
