Emissions Testing
Testing of Readiness Codes
Your vehicle has readiness code 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 properly if testing is performed just after the 12-volt
battery has gone dead or been disconnected.
To check if they are set, set the power mode to ON, without turning the power
system on. The malfunction indicator lamp will come on for several seconds. If it
then 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 ready,
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.
5. Select a nearby, lightly traveled major highway where you can maintain a speed
of 50 mph (80 km/h) over for at least 20 minutes. Drive on the highway in
(D
with SPORT+ mode. 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 power system off for 40 minutes.
1Testing of Readiness Codes
The readiness codes are erased when the 12-volt
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.
If the testing facility determines the readiness codes
are still not set, see a dealer.
