Traction
The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction
performance.
WARNING:
The traction grade assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction
characteristics.
n
Temperature
The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the
generation of heat and its ability to dissipate heat when tested under controlled conditions
on a specified indoor laboratory test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and
A represent higher levels of performance on the laboratory test wheel than the minimum
required by law.
WARNING:
The temperature grade for this tire is established for a tire that is properly
inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire failure.
Testing of Readiness Codes
Your vehicle has readiness codes as part of the onboard self-diagnostic system. Some states use these
codes for testing to verify your vehicle’s emissions components are working properly. The codes may
not be read if you go through the testing just after the battery has gone dead or been disconnected.
To check if they are set, turn the vehicle on without starting the engine. The malfunction indicator
lamp will come on for several seconds. If it goes off, the readiness codes are set. If it blinks five times,
the readiness codes are not set.
If you are required to have your vehicle tested before the readiness codes are set, prepare the vehicle
for retesting by doing the following:
1. Fill the gas tank to approximately 3/4 full.
2. Park the vehicle and leave the power system off for 6 hours or more.
3. Make sure the ambient temperature is between 40°F and 95°F (4°C and 35°C).
4. Turn the power system on without touching the accerator pedal and let it idle for 20 seconds.
5. Staying in Park (P), increase the engine speed to 2,000 rpm and hold it for about three minutes.
6. Let the engine idle for 20 seconds without touching the accelerator.
7. Select a nearby, lightly traveled major highway where you can maintain a speed of 50 mph (80
km/h) for at least 20 minutes. Drive on the highway with the vehicle in D and in SPORT mode. Do
not use cruise control.
8. Drive in city or suburban traffic for at least 10 minutes. When traffic conditions allow, let the
vehicle coast for several seconds without using the accelerator pedal or the brake pedal.
9. Park the vehicle and leave the power system off for 40 minutes.
The readiness codes are erased when the battery is disconnected and set again only after several days
of driving under a variety of conditions.
If a testing facility determines that the readiness codes are not set, you may be requested to return at
a later date to complete the test or see your authorized Acura NSX dealer.
