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 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.

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.
• For models equipped with automatic intermittent wipers, turn the wipers off.

• 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.

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.

Accessories and Modifications

Accessories

When installing accessories, check the following:
• Do not install accessories on the windshield. 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. 615

• Before installing any electronic accessory, have the installer contact a dealer for

assistance. If possible, have a dealer inspect the final installation.

• It is recommended to use genuine Acura roof bicycle racks for carrying bicycles.

Do not install load-carrying (strap-type) accessory racks to the tailgate, as they
may interfere with normal operation, which may result in damage to the tailgate.

If a Tire Goes Flat

Changing a Flat Tire

If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have the full-size tire repaired or
replaced.

1. Park the vehicle on firm, level, non-slippery surface and apply the parking brake.
2. Change the gear position to

Changing a Flat Tire

Follow compact spare precautions:
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm

2

)

When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.

The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not use another type of compact
spare tire or wheel with your vehicle.

Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.

Do not use a puncture-repairing agent on a flat tire,
as it can damage the tire pressure sensor.
