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 wh en 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: • Mount the tires to all four wheels.
For tire chains:• Install them on the rear tires only.
• Because your vehicle has limited tire clea rance, we strongly recommend using the
chains listed below:
*1:Tire chains to be used only on optional 295/30R20 winter tires.
*2:Tire chains to be used only on optional 305/30R20 winter tires.• Follow the chain manufactur er’s instruction when installing. Mount them as
tightly as you can.
• Check that the chains do not touc h the brake lines or suspension.
• Drive slowly.

NOTICE
Traction devices that are the wrong size or improperly
installed can damage your
vehicle’s brake lines,

When tire chains are mounted, follow the chain
manufacturer’s instructi ons regarding vehicle
operational limits.
If your vehicle is equipp ed with summer tires, be
aware that these tires are not designed for winter
driving conditions. For more information, contact an
authorized Acura NSX dealer.

Maintenance
Cold Weather Driving
Summer Only tires and Ultra High Performance (UHP) tires are very sensitive to
ambient temperatures and are designed to be used at temperatures above 45°F
(7°C). If the vehicle is operated with Summer Only tires or UHP tires at temperatures
below 45°F (7°C), the tires will provide decreasing amounts of grip and other
performance attributes. If the vehicle is operated with Summer Only tires or UHP
tires at temperatures below -4°F (-20°C), th e tire tread may lose their elasticity and
become brittle, resulting in permanent damage to the tread. A damaged tire may
fail during use. Therefore, if you operate the vehicle when ambient temperatures are
below 45°F (7°C), we recommend that you install other tires (e.g., mud+snow,
winter) that are designed to provide appropriate performance attributes under the
anticipated conditions.

3WARNING
Use of Summer Only tires or Ultra High
Performance tires at temperatures below
45°F (7°C) may lead to a loss of
performance and control, which could
result in a crash, se rious injury or death.

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 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 Minder TM
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.

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 igni ted during servicing if
proper procedures are not followed.

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.
Do not use an automated car wash. • Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. St anding 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.
