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 touch the brake lines or suspension.
• Drive slowly.

uuChecking and Maintaining Tires uCold Weather Driving
Maintenance
Cold Weather Driving
Summer Only tires and Ultra High Performan ce (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), the 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.1 Cold Weather Driving
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.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a sma ll puncture, from a small nail for instance,
you can use the temporary tire repair kit so that you can drive to the nearest service
station for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface. Apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Acura NSX dealer or a
roadside assistant to have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.
