Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE 
J2845) recommends that the refrigerant sy stem 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 wi th 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  and pollen filter sooner when using your 
vehicle in areas with high  concentrations of dust.
1Climate 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:

Do not spill liquids inside the vehicle. Electrical 
devices and systems may ma lfunction if liquids are 
splashed on them.
Do not use silicone based sp rays on electrical devices 
such as audio devices and switches. Doing so may 
cause the items to malfunction  or cause a fire inside 
the vehicle.
If a silicone based spray  is inadvertently used on 
electrical devices,  consult a dealer.
Depending on their compos ition, chemicals and 
liquid aromatics may cause  discoloration, wrinkles, 
and cracking to resin-ba sed parts and textiles.
Do not use alkali solvents or  organic solvents such as 
benzene or gasoline.
After using chemicals, make su re to gently wipe them 
away using a dry cloth.
Do not place used cloths on top of resin based parts 
or textiles for long periods  of time without washing.

Exterior Care
Dust off the vehicle body after you drive. Re gularly inspect your vehicle for scratches 
on painted surfaces. A scratch on a painted  surface can result in body rust. If you 
find a scratch, pr omptly repair it.
Wash the vehicle regularly. Wash more  frequently 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 inte rmittent wipers, turn the wipers off.
• Keep sufficient distance  between the cleaning nozzl e 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 directly  into the engine compartment. Instead, 
use low pressure water and a mild detergent.

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 lo se their luster or appear burn ished. To avoid water stains, 
wipe the wheels dry with a cloth while they are still wet.

Maintenance
The inside lenses of exterior lights (headli ghts, brake lights, etc.) may fog temporarily 
if you have driven in the rain, or after the vehicle has been run through a car wash.
Dew condensation also may build up inside  the lenses when there is a significant 
enough difference between the ambient and  inside-lens temperatures (similar to 
vehicle windows fogging up in rainy conditions). These conditions are natural 
processes, not structural design problems in the exterior lights.
Lens design characteristics may result in mo isture developing on the light lens frame 
surfaces. This also  is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops 
building up inside the lenses, have your vehicle inspected by a dealer.

Accessories and Modifications
Accessories
When installing accessories, check the following:
• Do not install accessories on the windsh ield. 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 overload  electrical circuits or interfere with 
proper operation of your vehicle.
2 Fuses  P. 670
•Before installing any electro nic accessory, have the installer contact a dealer for 
assistance. If possible, have a deal er inspect the final installation.

Honda Genuine accessor ies are recommended to 
ensure proper operati on on your vehicle.
3WARNING
Improper accessories or modifications can 
affect your vehicle's handling, stability, and 
performance, and cause a crash in which

make any modification to your vehicle or its systems that might cause your vehicle 
to no longer meet federal, state, prov ince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1962 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 any of the electrical components.
