jacking LINCOLN NAVIGATOR 2012 Owners Manual

position and flush the system (in particular the front and rear hinge
arms) with a high-pressure car wash wand.
Note:Do not use the running boards, front and rear hinge assemblies,
running board motors, or the running board under body mounts to lift
the vehicle when jacking. Please utilize proper jacking points. Refer to
Changing the tiresin theRoadside Emergencieschapter.
WARNING:In extreme climates, excessive ice buildup may
occur, causing the running boards not to deploy. Be sure that the
running boards have deployed, and have finished moving before
attempting to step on them. Note: The running boards will resume
normal function once the blockage is cleared.
WARNING:Turn off the running boards before jacking or
placing any object under the vehicle. Never place your hand
between the extended running board and the vehicle. A moving
running board may cause injury.
SPEED CONTROL
With speed control set, you can maintain a set speed without keeping
your foot on the accelerator pedal.

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 toMessage centerin theInstrument 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.
PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.

Tire change procedure
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block the
wheels (both front or both rear) on the opposite end of the vehicle
from the wheel being changed. If on a grade, block both opposite
wheels on the downward side of the hill.
WARNING:If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING:On vehicles equipped with air suspension, turn off
the air suspension system prior to jacking, hoisting or towing
your vehicle.
WARNING:Turn off the running boards (if equipped) before
jacking or placing any object under the vehicle. Never place your
hand between the extended running board and the vehicle. A moving
running board may cause injury.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack and changing the
wheel.
Note:Passengers should not remain in the vehicle when the vehicle is
being jacked.
If your vehicle is equipped with air suspension, refer toMessage center
in theInstrument Clusterchapter for instructions on turning the air
suspension system off.
Refer to the instruction sheet (located in the rear floor compartment
behind the 3rd row seat with the jack tray tools assembly kit) for
detailed tire change instructions.
