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 Filters
The climate control system is equipped wi th dust and pollen filters that collect
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filters.
We recommend that you replace the dust an d pollen filters sooner when using your
vehicle in areas with high concentrations of dust.

uuCleaning uExterior Care
Maintenance
If you get gasoline, oil, engine coolant, or battery fluid on resi n 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.

Maintenance
The inside lenses of exterior lights (headli ghts, brake lights, etc.) may fog temporarily
if you have driven in the rain. Dew condensation also may build up inside the lenses
when there is a significant enough differe nce between the ambient and inside lens
temperatures (similar to vehicle windows fogging up in rainy conditions). These
conditions are natural processes, not stru ctural design problems in the exterior
lights.
Lens design characteristics may result in mo isture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts of wa ter accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by an authorized Acura
NSX dealer.
Keep brake pads and rotors free of substances that are either abrasive or oil based,
as these substances can re duce brake system performance.
NSX brake pads and disks have a high meta llic content. Under certain conditions
these pad and disks may rust to varying degrees, which may cause a clunk noise or
rubbing sound if parked when brakes become wet. This is normal for brakes with
high friction pads and it does not affect operation of the brakes.
To prevent the iron contained in the brake pa ds and rotors from rusting and sticking,
brakes should be dried before parking the ve hicle after driving on wet roads or after
washing the vehicle (especially before long-term storage). To dry the brake pads and
rotors, drive the vehicle at a low sp eed and apply the brakes several times.
By regularly applying strong pressure to the brakes, you can reduce corrosion
buildup on the brake pads and rotors.

Brake maintenance require s specialized knowledge.
We recommend maintenance to be carried out by an
authorized Acura NSX dealer.
1 Maintenance of Brake Surfaces
Brakes can be dried by driv ing on a dry road for few
miles/kilometers, and a pplying the brake pedal
normally, based on traffic and road conditions. These
steps help maintain br ake system performance.

Keep the brake pads and rotors free of subs tances that are either abrasive or oil
based, as these substances can reduce br aking power. After driving in the presence
of salt and/or sand, briefly wash the ro tor/pad surfaces with low-pressure water,
then allow the brake system to dry. To dry the brake pads and rotors, drive the
vehicle at a low speed and apply the brakes several times.
Refer to the color code label and the te mperature notice label affixed to the
underside of the hood before painting the vehicle.

Storage
Vehicle Storage
If you need to park your vehicle for an extended period (more than one month),
there are several things you should do to prepare it for storage. This helps reduce
possible deterioration of vehicle components and overall condition, which allows
you to get the vehicle back on the road with minimal delay. These are:
• If possible, store your NSX in a garage or enclosed area.
• Fill the fuel tank completely.
• Change the engine oil and filter.
• Wash and dry the exterior completely.
• Clean the interior. Make sure the carpeti ng, floor mats, etc., are completely dry.
• Put the transmission in
(P.
Release the parking brake.
• Leave one window open slightly (if th e vehicle is being stored indoors).
• To maintain the low-voltage 12-volt battery, connect it to an accessory battery
charger. For more information on how to maintain your 12-volt battery, consult
an authorized Acura NSX dealer.
2 Checking the 12-Volt Battery P. 417
•If the vehicle is to be stored for a longer period of time, it should be supported on
jack stands to raise the tires off th e ground to prevent tire flat spotting.
2Handling of the Jack P. 446
•Support the front wiper blade arms with a folded towel or rag so they do not
touch the windshield.
• Cover the vehicle with a “breathable” co ver, one made from a porous material
such as cotton. Nonporous materials (suc h as plastic sheeting) may trap moisture,
which can damage the paint.
• If possible, remove the vehicle from th e garage or enclosed area, remove
covering, and periodically run the engi ne until it reaches full operating
temperature (the cooling fa n cycles on and off twice).
Preferably, do this once a month.

Handling the Unexpected
If the Check Engine Oil Level Warning Appears
■Reasons for the warning to appear
Appears when the engine oil level is low.
■What to do as soon as the warning
appears
1. Immediately park the vehicle on level
ground in a safe place.
2. If necessary, turn the hazard warning lights
on.
■What to do after parking the vehicle
Check the oil level.
2 Oil Check P. 391
1If the Check Engine Oil Level Warning Appears
NOTICE
Running the engine with a low oil level can cause
serious mechanical damage almost immediatelyM
This system activates after the engine warms up. If
the outside temperature is extremely low, you may
have to drive for a long time until the system senses
the engine oil levelM
If the warning appears again, turn the power system
off, and contact an authorized Acura NSX dealer for
repairs immediately.
