Winter Tires

If driving on snowy or frozen roads, mount all season marked M+S tires, snow tires,
or tire chains; reduce speed; and maintain sufficient distance between vehicles when
driving.

Be particularly careful when operating the steering wheel or brakes to prevent
skidding.

Use tire chains, snow tires, or all season tires when necessary or according to the
law.

When mounting, refer to the following points.

For winter tires:
• Select the size and load ranges that are the same as the original tires.
• Mount the tires to all four wheels.

WARNING

Using the wrong chains, or not properly
installing chains, can damage the brake
lines and cause a crash in which you can be
seriously injured or killed.

Follow all instructions in this owner’s
manual regarding the selection and use of
tire chains.

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 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 debris in the air. The Maintenance Minder

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.

Air Conditioning

NOTICE

Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one removed from a used or
salvaged vehicle.

Refrigerant in your vehicle’s air conditioning system is
flammable and can be ignited during servicing if
proper procedures are not followed.

The air conditioner label is found under the hood:

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.

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. Promptly 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 not 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.

The inside lenses of exterior lights (headlights, 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 light 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.
