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
-
Remove the center underhood apron (refer to
procedure).
-
Verify that the gauge on the nitrogen tank reads between 1000 and 3000
psi.
Warning: Failure to follow the next step might result in injury.
-
Turn the red ring on the secondary regulator all the way clockwise. This ensures
that the regulator is fully closed.
-
Attach the secondary regulator to the nitrogen tank.
-
Remove the safety cap from the vehicle’s air suspension reservoir fill
point.
-
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.
Warning: Before proceeding, ensure that the red ring on the secondary
regulator is closed by turning it all the way clockwise.
-
Attach the fill gauge to the secondary regulator.
-
Slowly turn the red ring on the secondary regulator counterclockwise. This
allows nitrogen to fill the secondary regulator.
-
Check the gauge on the secondary regulator to verify that it has pressure.
-
Open the upper knob on the fill gauge, which is secured to the reservoir fill point.
-
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.
-
Turn the red ring on the secondary regulator all the way clockwise to close
it.
-
Turn the red ring on the fill gauge all the way clockwise to close it.
