Driving STEERING To help prevent damage to the power steering system, never hold the steering wheel at its furthest turning points (until it stops) for more than a few seconds when the engine is running. It is also important to maintain a proper power steering fluid level in the power steering fluid reservoir: • Do not operate the vehicle with a low power steering pump fluid level. See Power steering fluid in the Maintenance and Specifications chapter. • Some noise is normal during operation. If the noise is excessive, check for low power steering pump fluid level before seeking service by your authorized dealer. • Heavy or uneven steering efforts may be caused by low power steering pump fluid level. Check for low power steering pump fluid level before seeking service by your authorized dealer. • Do not fill the power steering pump reservoir above the maximum level, as this may result in leaks from the reservoir. See Power steering fluid in the Maintenance and Specifications chapter. If the power steering system breaks down (or if the engine is off), you can steer the vehicle manually, but it takes more effort. If the steering wanders or pulls, check for: • an improperly inflated tire • uneven tire wear • loose or worn suspension components • loose or worn steering components • improper steering alignment AIR SUSPENSION SYSTEM (IF EQUIPPED) The air suspension system is designed to improve ride, handling and general vehicle performance during: • Certain road conditions • Steering maneuvers • Braking • Accelerations This system keeps the rear of your vehicle at a constant level by automatically adding air or releasing air from the springs. 187 2011 Town Car (tow) Owners Guide, 2nd Printing USA (fus)
