Each press of the MODE control will
display a different feature as follows:
Average fuel economy.The
display will indicate the vehicle’s
average fuel economy in liters/100
km (or miles/gallon) since the
average fuel economy was last reset.
If you calculate your average fuel
economy by dividing liters of fuel used by 100 kilometers traveled (miles
traveled by gallons used), your figure may be different than displayed for
the following reasons:
•your vehicle was not perfectly level during fill-up
•differences in the automatic shut-off points on the fuel pumps at
service stations
•variations in top-off procedure from one fill-up to another
•rounding of the displayed values to the nearest liter (gallon)
To reset the average fuel economy:
1. Press the MODE control repeatedly until average fuel economy is
displayed (this is the only resettable display).

Replacing the batteries
The keyless entry keypad uses one coin-type three-volt lithium battery
(Service Part Number 3L2W-19G545–A). This replacement battery is only
available through your authorized dealer.
To replace the battery:
1. Use the largest flathead screwdriver that will insert into the slot on
the right side of the keypad. Gently twist the screwdriver to pry off the
top cover. Pull the cover off by pulling to the left and then up. The top
cover and the internal components of the keypad will come off the
vehicle and the back cover will remain mounted to the vehicle.
2. Remove the internal components of the keypad from the top cover
and place the top cover on a soft surface to avoid scratching the
decorative finish.Note:Donotremove the silicone rubber membrane
from the rest of the electronics.
3. Insert the screwdriver into one of the two slots on the metal battery
holder, located on either side of the (+) indicator. The battery will then
slide out enough to obtain with your fingers.
4. Remove the old battery from the
unit and replace it with a new
battery, ensuring that the (+)
indicator is properly aligned
properly and seated completely
inside the battery holder.
5. Replace the keypad internal
components back inside the top
cover.Note:Ensure the screwdriver
slot is located next to the 9•0
keypad.
6. Hold the top cover and the internal components together, align the
unit with the back cover mounted on the vehicle, and press the two
pieces together. Run your finger around the perimeter of the keypad to
ensure it is properly seated.
7. Press the 7•8 and the 9•0 controls simultaneously to lock the
vehicle and to verify the keypad is functioning properly.
Note:Replacement of the battery willnotcause the remote keyless
keypad to become deprogrammed from your vehicle. The remote keyless
keypad should operate normally after battery replacement.

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 such as snowplow equipment may effect
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.
Removing the blocker beam without installing snow plow
attachment hardware may effect air bag deployment in a crash.
Do not operate the truck unless either the blocker beam or snow plow
attachment hardware is installed on the vehicle.

The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system wiring (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAir bag readinesssection
in theInstrument clusterchapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after
ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.
Passenger air bag ON/OFF switch
An air bag ON/OFF switch
has been installed in this
vehicle. Before driving,always
look at the face of the switch to
be sure the switch is in the proper
position in accordance with these
instructions and warnings. Failure
to put the switch in a proper
position can increase the risk of
serious injury or death in a
collision.PASSENGER AIR BAG

Turning the passenger air bag off
1. Insert the ignition key, turn the
switch to OFF position and hold in
OFF position while removing the
key.
2. When the ignition is turned to the
ON position the OFF light
illuminates briefly, momentarily
shuts off and then turns back on.
This indicates that the passenger air
bag is deactivated.
If the light fails to illuminate when the passenger air bag switch
is in the OFF position and the ignition switch is in ON, have the
passenger air bag switch serviced at your Ford or Lincoln-Mercury
dealer immediately.
In order to avoid inadvertent activation of the switch, always
remove the ignition key from the passenger air bag ON/OFF
switch.
An infant in a rear-facing seat faces a high risk of serious or fatal
injuries from a deploying passenger air bag. Rear facing infant
seats should NEVER be placed in the front seats, unless the passenger
air bag is turned off.
Turning the passenger air bag back on
The passenger air bag remains OFF until you turn it back ON.
1. Insert the ignition key and turn
the switch to ON.
2. The OFF light will briefly
illuminate when the ignition is
turned to On. This indicates that the
passenger air bag is operational.

If the OFF light is illuminated when the passenger air bag switch
is in the ON position and the ignition switch is in ON, have the
passenger air bag switch serviced at your Ford or Lincoln-Mercury
dealer immediately.
The passenger side air bag should always be ON (the air bag OFF light
shouldnotbe illuminated) unless the passenger is a person who meets
the requirements stated either in Category 1, 2 or 3 of the
NHTSA/Transport Canada deactivation criteria which follows.
The safety belts for the driver and right front passenger seating
positions have been specifically designed to function together
with the air bags in certain types of crashes. When you turn OFF your
air bag, you not only lose the protection of the air bag, you also may
reduce the effectiveness of your safety belt system, which was
designed to work with the air bag. If you are not a person who meets
the requirements stated in the NHTSA/Transport Canada deactivation
criteria turning OFF the air bag can increase the risk of serious injury
or death in a collision.
If your vehicle has rear seats, always transport children who are
12 and younger in the rear seat. Always use safety belts and
child restraints properly. If a child in a rear facing infant seat must be
transported in front, the passenger air bagmustbe turned OFF. This is
because the back of the infant seat is too close to the inflating air bag
and the risk of a fatal injury to the infant when the air bag inflates is
substantial.
The vast majority of drivers and passengers are much safer with an air
bag than without. To do their job and reduce the risk of life threatening
injuries, air bags must open with great force, and this force can pose a
potentially deadly risk in some situations, particularly when a front seat
occupant is not properly buckled up. The most effective way to reduce
the risk of unnecessary air bag injuries without reducing the overall
safety of the vehicle is to make sure all occupants are properly
restrained in the vehicle, especially in the front seat. This provides the
protection of safety belts and permits the air bags to provide the
additional protection they were designed to provide. If you choose to
deactivate your air bag, you are losing the very significant risk reducing
benefits of the air bag and you are also reducing the effectiveness of the
safety belts, because safety belts in modern vehicles are designed to
work as a safety system with the air bags.

Using the engine block heater (if equipped)
Use of an engine block heater is
strongly recommended if you live in
a region where temperatures reach
-23°C (-10°F) or below. For best
results, plug the heater in at least
three hours before starting the
vehicle. The heater can be plugged
in the night before starting the
vehicle. The plug for the block
heater is exposed in the front of the
vehicle, beneath the grille. Vehicles
equipped with a gasoline engine have the plug exposed on the driver
side of the vehicle; vehicles equipped with a Diesel engine have the plug
exposed on the passenger side of the vehicle.
To reduce the risk of electrical shock, do not use your heater
with ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
