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 battery has 
gone dead or been disconnected.

To check if they are set, turn the ignition switch to ON 

(

, without starting the 

engine. 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 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 

(

P (continuously variable transmission) or 

(

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.

*1: Models with the smart entry system have an ENGINE START/STOP button instead of an 
ignition switch.

Testing of Readiness Codes

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.

If the testing facility determines the readiness codes 
are still not set, see a dealer.

of 50 to 60 mph (80 to 97 km/h) for at least 20 minutes. Drive on the highway in

D (continuously variable transmission) or 5th (manual transmission). 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.
