Tight tolerance mode is used to "lock" the air suspension, when doing an alignment.

How to set the tight tolerance mode;
- Put the Gearbox in PARK
- Start the engine
- Set the suspension to Normal Height
- Open the driver’s door
- Press the brake pedal lightly 3 times, letting the pedal come up fully each time
- And close the door within 10 seconds from first press of the brake pedal
- There will be 2 chimes from the instrument cluster after the door is closed, if successful
- Each time the door is opened and closed, 2 chimes will sound, indicating it is still in tight tolerance mode.
- To deactivate:
- Either turn the engine off, or drive it over 5 mp/h
- If you were to use this procedure for wheel alignment, you need to have the engine running the whole time.
