1999 Mercury Mountaineer relay

The air suspension shut-off switch is
located in the cargo area behind the
left rear quarter trim panel.
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.
TRANSMISSION OPERATION
Automatic transmission operation
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
depressed.
If you cannot move the gearshift out of P (Park) with the brake pedal
depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N
(Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift, it is
possible that a fuse has blown or the vehicle's brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.

The fuel pump shut-off switch is
located in the passenger's foot well,
behind the kick panel.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause
severe wire damage and could start a fire.
