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.

delay your reaction to driving conditions.
• Do not install any access ories over areas marked SRS AIRBAG, on the sides or
backs of the 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 over load electrical circuits or interfere with
proper operation of your vehicle. 2 Fuses P. 457
• Before installing any electronic accessory, have the installer contact an authorized
Acura NSX dealer for assistance. If possibl e, have an authorized Acura NSX dealer
inspect the final installation.
1Accessories and Modifications

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.

1.Remove the valve cap from the tire valve
stem.
2. Shake the sealant bottle.
3. Attach the sealant/air hose onto the tire
valve stem. Screw the sealant/air hose
until it is tightly connected to the valve
stem.
uMake sure the bottle remains upright to
ensure all the sealant flows into the tire.
4. Remove the bottle cap from the bottle

5. Attach the air compre ssor hose onto the
bottle adapter. Screw the air compressor
hose until it is tightly connected to the
bottle adapter.
■Injecting Sealant and Air1Injecting Sealant and Air
Keep the sealant bottle out of the reach of children.
Do not shake the bottle after the bottle cap removed.
If you shake the bottle after the cap is removed, it
may spill sealant.
In cold temperatures, the sealant may not flow easily.
In this situation, warm it up for five minutes before
using.
The sealant is latex based and can permanently stain
clothing and other materi als. Be careful during
handling and wipe up an y spills immediately.
3WARNING
Tire sealant contains substances that are
harmful and can be fatal if swallowed.
If accidentally swallowed, do not induce
vomiting. Drink plenty of water and get
medical attention immediately.
For skin or eye contact, flush with cool
water and get medical attention if
necessary.

1Injecting Sealant and Air
NOTICE
Do not operate the temporary tire repair kit compressor
for more than 15 minutes. The compressor can overheat
and become permanently damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begi n to rise again as the tire
is inflated with air. This is normal. To accurately measure
the air pressure using the gauge, turn the air compressor
off only after the sealan t injection is complete.
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal and your vehicle
will need to be towed.
See an authorized Acura NSX dealer for a replacement
sealant bottle and proper disposal of an empty bottle.
