Tesla Model S: Air Suspension - Pressurize - Full System

Add Nitrogen to the Air Reservoir System

Warning: Wear eye protection while performing this procedure.

Caution: Tesla recommends using a nitrogen refill kit to refill the air suspension reservoir. Do not use shop air, which might contain contaminants that could damage the air suspension system.

Nitrogen Refill Kit

1. Remove the center underhood apron (refer to procedure).
2. Verify that the gauge on the nitrogen tank reads between 1000 and 3000 psi.

   

3. Turn the red ring on the secondary regulator all the way clockwise. This ensures that the regulator is fully closed.

   

4. Attach the secondary regulator to the nitrogen tank.

   

5. Remove the safety cap from the vehicle's air suspension reservoir fill point.

   

6. Tighten the nut that secures the fill gauge to the reservoir fill point.

   Caution: Ensure that the upper knob is closed by turning it all the way counterclockwise.

   

7. Attach the fill gauge to the secondary regulator.

   

8. Slowly turn the red ring on the secondary regulator counterclockwise. This allows nitrogen to fill the secondary regulator.
9. Check the gauge on the secondary regulator to verify that it has pressure.

   

10. Open the upper knob on the fill gauge, which is secured to the reservoir fill point.

    

11. Slowly turn the red knob on the fill gauge to allow nitrogen into the air suspension reservoir. Adjust the knob until the fill gauge reads 150 psi.

    

12. Turn the red ring on the secondary regulator all the way clockwise to close it.
13. Turn the red ring on the fill gauge all the way clockwise to close it.
