So let’s say you have a friend, relative, or acquaintance who is on the heavier side of heavy. You and your significant other pull up in your new Cadillac XTS to pick him and significant other up for a night on the town. All’s swell until he gets in the back seat behind the passenger, at which point the Caddy sinks like a stone, nearly placing the right rear wheel well on the tire right rear tire. He is that heavy. Now, all four of you do the crab-like sideways crawl drive to dinner in a lob-sided XTS… right? Wrong, thanks to the Automatic Level Control rear suspension.
Standard on all XTS models, the automatic level control rear suspenders provide a better-leveled riding position as well as better handling under a variety of passenger and loading conditions.
The system works thanks to an air compressor that’s connected to the rear air springs. It’s this compressor that raises or lowers the rear of the XTS to maintain proper vehicle height. A tell-tale sign that the system is raising the XTS is the somewhat-noticeable noise made by the air compressor when it’s in action. So, when your buddy gets in and you hear a quiet motor while the car’s rear end raises, you know it’s the Automatic Air Springs at work. Pretty nifty, right?
A few things to know about the air Automatic Control Feature:
- The system is active only when the engine is running, automatically adjusting vehicle height as needed.
- The system may exhaust (lower vehicle height) for up to 10 minutes after the engine has been turned off. You may hear the air compressor operating when the height is being adjusted.
- If the vehicle is not used for several weeks, the rear of the vehicle may look low. The proper height is automatically restored when the engine is started.
- If a weight-distributing hitch is being used, it is recommended to allow the air springs to inflate, thereby leveling the vehicle prior to adjusting the hitch.
- If the compressor runs often for longer than one minute within the same trip and the vehicle remains low in the rear, see your dealer to service the system.
