NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you've parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

Checking Wiper Blades
If the wiper blade rubber has deteriorated, it will leave streaks and the hard surfaces
of the blade may scratch the window glass.
Changing the Wiper Blade Rubber
1. Turn the ignition switch to LOCK (0*1.
2. While holding the wiper switch in the MIST
position, turn the ignition switch to ON
(w*1, then to LOCK (0*1.
u Both wiper arms are set to the
maintenance position as shown in the
image.
3. Lift both wiper arms.
*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.

NOTICE
Avoid dropping the wiper arm onto the windshield, it
may damage the wiper arm and/or the windshield.

Maintenance
Heating System*/Climate Control System* Maintenance
Air Conditioning*
To ensure proper and safe operation, the 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 heating system*/climate control system* is equipped with a dust and pollen filter
that collects pollen, dust, and other de bris 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.
1Heating System*/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:

■Cleaning Seat Belts
1 Interior Care
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 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.

Maintenance
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 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 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 directly into the engine compartment. Instead,
use low pressure water and a mild detergent.

■Using an Automated Car Wash
■Using High Pressure Cleaners
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

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.
