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
- 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.
Use Toolbox to Fill the Air Springs
Use the Toolbox "Air Suspension Fill/Deflate" panel to pressurize
the air springs.
