Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant system only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning 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.
Dust and Pollen Filter
The climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust a nd pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:

If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehicle for scratches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more fr equently when driving in the following
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
• Make sure to follow the instructions indicated on the automated car wash.
• Fold in the door mirrors.
• For models equipped with automatic intermittent wipers, turn the wipers off.
• Keep sufficient distance between the cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water direct ly into the engine compartment. Instead,
use low pressure water and a mild detergent.

1 Washing the Vehicle
Do not spray water into the air intake vents. It can
cause a malfunction.
Do not spray water onto the capless unit when the
fuel fill door is open. It ca n cause damage to the fuel
system or engine.
If you need to lift the wiper arms away from the
windshield, first set the wiper arms to the

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lose their luster or appear burnished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windshield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of the
vehicle’s airbags or may be propelled into you or another occupant if the airbags
deploy.
• Be sure electronic accessories do not over load electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 657
•Before installing any electron ic accessory, have the installer contact a dealer for
assistance. If possible, have a d ealer inspect the final installation.
1Accessories and Modifications
Honda Genuine accessor ies are recommended to
ensure proper operati on on your vehicle.

affect your vehicle's handling, stability, and
performance, and cause a crash in which
you can be seriously hurt or killed.
Follow all instruction s in this owner's
manual regarding accessories and
modifications.
3WARNING
Use of improperly designed, engineered or
manufactured high-voltage battery
assemblies could cause a fire in your

Maintenance
Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Honda pa rts or accessories that may have a similar
effect.
Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is properly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, pr ovince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1 962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Honda has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.
Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical syst ems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle’ s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Honda high-
voltage battery assembly. Genuine Honda high-voltage battery assemblies are
designed to work with your vehicle’s hybrid power system and have been designed,
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have b een similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

NOTICE
Do not operate the temporary tire repair kit
compressor for more than 15 minutes. The
compressor can overheat and become permanently
damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usin g the gauge, turn the air
compressor off only after the sealant injection is
complete.

Handling the Unexpected
If the 12-Volt Battery Is Dead
Turn off the power to electric devices, such as audio and lights. Turn off the power
system, then open the hood. 1.Open the terminal cover on your vehicle’s
12-volt battery positive + terminal.
2. Connect the first jumper cable to your
vehicle's 12-volt battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u
When using an automotive battery charger
to boost your 12-volt battery, select a
lower charging voltage than 15-volt. Check
the charger manual for the proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1If the 12-Volt Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
12-volt battery performa nce degrades in cold
conditions and may prevent the engine from starting.
3WARNING
A 12-volt battery can explode if you do not
follow the correct procedure, seriously
injuring anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the 12-volt battery.
