Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, the 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 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.
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 repl ace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Air Conditioning
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:

Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehi cle 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 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. St anding 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.

1 Washing the Vehicle
Do not spray water into the air intake vents. It can
cause a malfunction.
Do not spray water onto the fuel fill door directly. A
high-pressure spray ma y cause it to open.
Do not spray water onto the capless unit when the
fuel fill door is open. It ca n cause damage to the fuel

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 resi n 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.

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
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 si de 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.
