MAINTENANCE
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. Start the engine without touching the accelerator pedal, and let it idle for 20
seconds.
5. Keep the vehicle in PARK (P) (continuously variable transmission) or
NEUTRAL (N) (manual transmission). Increase the engine speed to 2,000
rpm, and hold it there for about 3 minutes.
6. Let the engine idle with your foot off the accelerator for 20 seconds.
7. 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 in DRIVE (D) (continuously variable transmission) or 5th (manual).
Do not use cruise control. When traffic allows, drive for 90 seconds without
moving the accelerator pedal. (Vehicle speed may vary slightly; this is okay.)
If you cannot do this for a continuous 90 seconds because of traffic
conditions, drive for at least 30 seconds, then repeat it two more times (for a
total of 90 seconds).
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 engine off for 30 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.
