AUXILIARY POWER POINT
Power points are designed for accessory plugs only. Do not hang
any type of accessory or accessory bracket from the plug.
Improper use of the power points can cause damage not covered
by your warranty.
An auxiliary power point is located
by the passenger ’ s ankle near the
floor in the front console bin.
Do not plug optional electrical
accessories into the cigarette lighter.
Use the power point.
Do not use the power point for
operating the cigarette lighter
element.
The Maximum power each power
point can supply depends on the fuse rating. For example: a 20A fuse
should supply a maximum of 240 Watts, a 15A fuse should supply a
maximum of 180 Watts and a 10A fuse should supply a maximum of 120
Watts. Exceeding these limits will result in a blown fuse.
Always keep the power point caps closed when not being used.
A second auxiliary power point is
located inside the cupholder door
on the rear side of the center
console. The power point is
accessible from the rear seats. 43210

• on the owner ’ s wallet card in the glove compartment,
• at your dealer,
• or on the module located under
the right-hand side of the
instrument panel, adjacent to the
passenger compartment fuse
panel.
Note: The 5 – digit code (e.g. 12345)
will be in large, BOLD numbers on
the module label.
When pressing the controls on the keyless entry keypad, press the
middle of the controls to ensure a good activation.
Programming your own personal entry code
To program your own code:
6. Enter factory set code (keypad will illuminate when pressed).
7. Press 1/2 control within five seconds of step 1.
8. Enter your personal 5 digit code.
Enter each digit within five seconds
of previous one.
9. After the code is entered, the
locks will cycle, confirming that the
new code has been set.
Do not set a code that includes five of the same number or presents
them in sequential order. Thieves can easily figure out these types of
codes.

Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 25 cm (10 inches)
between an occupant ’ s chest and the driver air bag module.
Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the air bag:
• Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
• Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the air bag system, increasing
the risk of injury. Do not modify the front end of the vehicle.
Additional equipment may affect the performance of the air bag
sensors increasing the risk of injury. Please refer to the Body
Builders Layout Book for instructions about the appropriate installation
of additional equipment.

Do not attempt to service, repair, or modify the Safety Canopy
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy . See your Ford or Lincoln
Mercury dealer.
All occupants of the vehicle including the driver should always
wear their safety belts even when an air bag SRS and Safety
Canopy system is provided.
To reduce risk of injury, do not obstruct or place objects in the
deployment path of the inflatable Safety Canopy .
How does the Safety Canopy system work?
The design and development of the
Safety Canopy system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Air Bag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy ).
The Safety Canopy system
consists of the following:
• An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of vehicle).
• A headliner designed to flex open
above the side doors to allow Safety Canopy deployment.
• The same warning light, electronic control and diagnostic unit as used
for the front airbags.

Do not alter or modify your vehicle ’ s suspension or steering; the
resulting changes to the vehicle ’ s handling can adversely affect
the Roll Stability Control system. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the Roll
Stability Control sensors located in this area.
Note: Pressing the Roll Stability Control button will disable the Roll
Stability Control.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an Roll Stability Control
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
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 depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed, it is possible that a fuse
has blown or the vehicle ’ s brakelamps are not operating properly. Refer
to Fuses and relays in the Roadside emergencies chapter.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.

The fuel pump shut-off switch has a
red reset button on top of it and is
located beneath the air suspension
switch (if equipped). If the vehicle
is not equipped with air suspension,
the fuel pump shut-off switch ’ s red
reset button will still be visible
behind this access panel.
Use the following procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
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. 15
