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 whether 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, set the power mode to 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 engine 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.
5. Select a nearby, lightly traveled major highway where you can maintain a
speed of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the
highway with the vehicle in Drive. Do not use cruise control.
6. 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.
7. Park the vehicle and leave the engine off for 40 minutes.
The readiness codes are erased when the battery is disconnected. The codes
are 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 dealer.
