Climate Control System Maintenance

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 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.

Dust and Pollen Filter

If the airflow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.

Interior Care

Do not spill liquids inside the vehicle. Electrical
devices and systems may malfunction 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 composition, chemicals and
liquid aromatics may cause discoloration, wrinkles,
and cracking to resin-based parts and textiles.
Do not use alkali solvents or organic solvents such as
benzene or gasoline.

After using chemicals, 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.

Do not put additional floor mats on top of
the anchored mats.

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 dampened with a solution comprised of 90%

water and 10% neutral soap.

3. Wipe away any soap residue with a clean damp cloth.
4. Wipe away residual water and allow leather to air dry in the shade.

Maintaining Genuine Leather

It is important to clean or wipe away dirt or dust as
soon as possible. Spills can soak into leather resulting
in stains. Dirt or dust can cause abrasions in the
leather. In addition, please note that some dark
colored clothing can rub onto the leather seats
resulting in discoloration or stains.

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.

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.

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. 658

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

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

Accessories and Modifications

Acura Genuine accessories are recommended to
ensure proper operation on your vehicle.

WARNING

Improper accessories or modifications can
affect your vehicle’s handling, stability, and
performance, and cause a crash in which
you can be seriously hurt or killed.

Modifications

Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Acura parts or accessories that may have a similar
effect.

Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is properly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, province, territory, and local regulations.

The on-board diagnostic port (OBD-II/SAE J1962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Acura has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.

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

3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF

(LOCK).

Changing a Flat Tire

*

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 other than the
one provided in the kit that came with your vehicle (if
equipped). If a different agent is used, you may
permanently damage the tire pressure sensor.
