2005 Essex - Dash Auxiliary Air Switch

Would appreciate information on the purpose and function of the auxiliary air dash switch to the left of the steering wheel. I understand that it operates a small air pump in connection with air leveling of the coach, but the instructions for air leveling do not reference this switch so I am not sure what its function is or how/when it is to be used. Thanks to all.

I'd love to know the same thing. I've tried pressing that toggle switch and nothing at all seems to happen.

Air” Leveling
The “Air” leveling system is designed to be used for minor, temporary leveling
of the unit (when overnight camping in a parking lot, for example) for basic
comfort and convenience. Please note that while this will bring the unit to a
“relatively” level stance while on slightly sloped surfaces, it does not deploy
the hydraulic leveling jacks to raise the unit significantly or stabilize the unit
on the ground. As a result, you may still experience some movement of the
coach when walking through it.
To level your unit using the “air” system, be sure the unit is parked securely
and the parking brake is set. Then:
1. Turn the ignition key to the “ACC” position, and press the “AIR” button
to enter the “Air” leveling mode (“Leveling System Active” light will
glow steadily, and the 4 red “Warning” lights will come on to indicate the

ride height valves have been locked out. NEVER move the vehicle when

these red lights are on!)
2. Press the “Air” button again, and the Leveling System Active” light will
begin to flash to indicate that leveling has begun. The system will attempt
to level the unit by dumping air individually from the suspension air bags.

The yellow “Level Sensing” lights will go out gradually as the unit

becomes level. When all the yellow “Level Sensing” lights are out,
leveling is complete. The “Leveling System Active” light will begin to
pulsate dimly to indicate the system is in “Sleep” mode. In this mode,

though no lights are visible on the control panel, the system is active, and

will re-check the coaches state of “level” every half hour, re-leveling it as
3. The system will remain in “Sleep Mode” until, -1- the ignition is turned
on, -2- the parking brake is released, or -3- the “Emergency Stop” button
is pressed. The system will only return to the “Travel” mode when the

“Store” button is depressed, or the parking brake is released. In either

situation, the ignition key must be in the “ON” position.

It is in your manual.If you do not have one-----

Hello Mt Bob,
Thanks so much for your response. What my question concerned was not so much the operating procedure for air leveling as I am well aware of that, but rather the purpose and function of the auxilliary air switch located on the dash to the left of the steering column. I recently wrote to Newmar Customer Service to get this information since I have not seen anything about it in the manual. If and when I get a response, I will share it with you and DandyDon. Thanks again.

2005 Essex - Dash Auxiliary Air Switch

DandyDon and Mt Bob,

I received a response from Newmar Customer Service regarding the auxiliary air switch on the dash. I was advised as follows:

"The Aux air switch would have been used to turn on the compressor without having to start the coach. This would allow you to air a tire up, etc."

This clears it up for me, hope it does for you as well.
