When you find corrosion, cl ean the battery terminals
by applying a baking powder and water solution.
Clean the terminal with a damp towel. Cloth/towel
dry the battery. Coat the terminals with grease to
help prevent future corrosion.
When replacing the battery, the replacement must be
of the same specifications.

Maintenance
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 replace the dust an d 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:

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 sprays 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 chemical s, make sure 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.

The driver position and rear passenger side
floor mats hook over floor anchors, which
keep them from sliding forward. To remove a
mat for cleaning, turn th e anchor knobs to the
unlock position. When reinstalling the mat
after cleaning, turn the knobs to the lock
position.
Do not put additional floor mats on top of
the anchored mat.
To properly clean leather:
1. Use a vacuum or soft dry cloth first to remove any dirt or dust.
2. Clean the leather with a soft cloth dampen ed with a solution comprised of 90%
water and 10% neutral soap.
3. Wipe away any soap residu e with a clean damp cloth.
4. Wipe away residual water and allo w leather to air dry in the shade.
■Floor Mats1Floor Mats
If you use any floor mats that were not originally
provided with your vehicle, make sure they are
designed for your specific ve hicle, fit correctly, and
are securely anchored by the floor anchors.
Position the rear-seat floor mats properly. If they are
not properly positioned, the floor mats can interfere
with the front seat functions.

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.
• Turn off the automatic intermittent wipers
*.
• 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.

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

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.

The inside lenses of exterior lights (headlig hts, 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 moisture developing on the lens frame
surfaces. This also is not a malfunction. However, if you see large amounts of water
accumulation, or large water drops building up inside the lenses, have your vehicle
inspected by a dealer.
