Driving • Do not operate the vehicle with a low power steering pump fluid level (below the MIN mark on the reservoir). • 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 MAX mark on the reservoir, as this may result in leaks from the reservoir. If the power steering system breaks down (or if the engine is turned 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 Speed sensitive steering The steering in your vehicle is speed sensitive. At high speeds, steering assist will decrease to improve steering feel. At lower speeds, maneuverability will be increased. If the amount of effort required to steer your vehicle changes while driving at a constant vehicle speed, have the power steering system checked by your authorized dealer. 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. 177 2006 Grand Marquis (grn) Owners Guide (post-2002-fmt) USA (fus)
