Lincoln 2011 Navigator Automobile User Manual


 
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:
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
AIR SUSPENSION SYSTEM
The air suspension system is designed to improve ride, handling and
general vehicle performance during:
Certain road conditions
Steering maneuvers
Braking
Acceleration
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. The air
suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension system can be enabled or disabled through the
message center. Refer to Message center in the Instrument Cluster
chapter.
If the system is off, the rear air suspension will not operate and will not
raise (pump) or lower (vent) while the vehicle is not moving. However, if
the system determines that the vehicle is low or high and needs to make
a height adjustment while driving at speeds above 15 mph (24 km/h), the
system will pump or vent as required. Normal vehicle operation does not
require any action by the driver.
WARNING: On vehicles equipped with air suspension, turn the
air suspension and the ignition switch off prior to jacking,
hoisting or towing your vehicle.
