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.

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

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.

■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.

Maintenance
• The vehicle must be in a stationary condition.
u Make sure your vehicle is parked on leve l ground, the parking brake is set, and
the power system is turned off.
• Be aware that hot parts can burn you.
u Make sure to let the power system incl uding the engine and exhaust system
cool thoroughly before touching vehicle parts.
• Be aware that moving parts can injure you.
u Do not activate the power system unle ss instructed, and keep your hands and
limbs away from moving parts. When the power mode is on, the engine can
automatically start, or the radiator fan may start operating without the engine
running.
Parts and Fluids Used in Maintenance Service
The use of Honda genuine parts and fluids is recommended when maintaining and
servicing your vehicle. Honda genuine parts are manufactured according to the

certified technicians.
Never repair or replace the air conditio ning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.1 Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
