4.  Test-drive the vehicle for at least 

1 minute 

above 

22 mph

. If the MID does not show the tire pressures, make sure 

you completed the test-drive as specified. 

NOTE: This vehicle does not have a spare tire. Instead, it comes with a tire repair kit stored under the trunk lining. 
An optional spare tire wheel kit can be ordered separately. 

 

Under-Hood (Engine Idling)

 

12. 

Do the PCM Idle Learn Procedure

 

To ensure a steady engine idle, do the PCM idle learn procedure as follows after installing the No. 17 BACKUP (10 A) 
fuse. 

NOTE: The PCM idle learn procedure must also be done after updating or replacing the PCM. It does not need to be 
done after clearing DTCs. 

1.  Start the engine with the transmission in Park, and make sure all electrical items (A/C, audio unit, rear window 

defogger, lights, etc.) are turned off. 

2.  Let the engine idle for 

10 minutes 

with the throttle fully closed. 

3.  Turn the ignition to OFF. 

 

13. 

Do the CKP-Pattern Learn Procedure

 

To ensure proper engine operation, do the CKP-pattern learn procedure after doing the PCM idle learn procedure. Do it 
on a level road during your TQI test-drive. 

NOTE: 

• 

Make sure all electrical loads (A/C, heated seats, audio unit, etc.) are turned off before doing this procedure. 

• 

Failure to do this procedure correctly may result in poor drivability along with misfire DTCs.

 

 

1.  While driving on a level road, decelerate from 

2,500 rpm

 to 

1,000 rpm

 with the transmission in 2nd gear (check to 

see which gear via the steering wheel paddle shifter) and the throttle fully closed. 

2.  Repeat step 1 three times.
