Mercury Grand Marquis 2002 - Manual (Page 147)

If the steering wanders or pulls, the condition could be caused by any of
the following:
• underinflated tire(s) on any wheel(s)
• uneven vehicle loading
• high crown in center of road
• high crosswinds
• wheels out of alignment
• loose or worn suspension components
Speed sensitive steering (except police vehicles)
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 at a
constant vehicle speed, have the power steering system checked by your
dealer or a qualified service technician.
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.
If you exceed the load limit, the rear air suspension may not operate.
