jacking Mercury Grand Marquis 2009 Owner's Manuals

If you exceed the load limit, the rear air suspension may not operate.
The air suspension shut-off switch is
located on the left side of the trunk.
If this switch is in the off position,
the rear air suspension will not
operate.
WARNING:On vehicles
equipped with air
suspension, turn off the air
suspension switch prior to jacking,
hoisting or towing your vehicle.
Normal vehicle operation does not
require any action by the driver.
TRACTION-LOK™ AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok™ axle functions like a standard rear axle.
Extended use of other than the manufacturer’s specified size tires on a
Traction-Lok™ rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
AUTOMATIC TRANSMISSION OPERATION
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the on position unless brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brakelamps are not operating properly. Refer to
Fuses and relaysin theRoadside Emergencieschapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to 2 (Accessory).
