WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
lights work. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Service engine soon: TheService
engine soon indicator light
illuminates when the ignition is first
turned to the ON position to check
the light function. Solid illumination after the engine is started indicates
the On Board Diagnostics System (OBD-II) has detected a malfunction.
Refer to On board diagnostics (OBD-II) in theMaintenance and
Specifications chapter. If the light is blinking, engine misfire is occurring
which could damage your catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and deceleration) and have your
vehicle serviced immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Brake system warning light: To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position
when the engine is not running or by applying the parking brake when
the ignition is turned to the ON position. If the brake system warning
light does not illuminate at this time, seek service immediately from your
dealership. Illumination after releasing the parking brake indicates low
brake fluid level and the brake system should be inspected immediately
by your servicing dealership.

Note:Large metallic objects, electronic devices that are used to
purchase gasoline or similar items, or a second coded key on the same
key chain may cause vehicle starting issues. You need to prevent these
objects from touching the coded key while starting the engine. These
objects will not cause damage to the coded key, but may cause a
momentary issue if they are too close to the key when starting the
engine. If a problem occurs, turn the ignition off, remove all objects on
the key chain away from the coded key and restart the engine.
Theft indicator
The theft indicator is located on the instrument panel, below the
Boost/Vac gauge.
• When the ignition is in the 3 (ON) position, the indicator will glow for
3 seconds, then turn off, to indicate normal system functionality.
If a problem occurs with the SecuriLock system, the indicator will flash
rapidly or glow steadily when the ignition is in the 3 (ON) position. If this
occurs, the vehicle should be taken to an authorized dealer for service.
Replacement keys
If your keys are lost or stolen and you don ’t have an extra coded key,
you will need to have your vehicle towed to a dealership. The key codes
need to be erased from your vehicle and new coded keys will need to be
programmed.
Replacing coded keys can be very costly. Store an extra programmed key
away from the vehicle in a safe place to help prevent any
inconveniences. Please visit an authorized dealer to purchase additional
spare or replacement keys.
Programming spare keys
You can program your own coded keys to your vehicle. Please read and
understand the entire procedure before you begin.
Tips:
• A maximum of eight keys can be coded to your vehicle.
• Only use SecuriLock keys.
• You must have two previously programmed coded keys (keys that
already operate your vehicle ’s engine) and the new unprogrammed
key(s) readily accessible.
•
If two previously programmed coded keys are not available, you must
take your vehicle to your dealer to have the spare key(s) programmed.

4. Open the engine compartment cover. Protect yourself from engine
heat.
5. Locate and carefully remove the engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert
the indicator fully, then remove it
again.
Check oil level within 1 minute of
shutting off the vehicle.
•If the oil level is between the MIN—MAX marks, the oil level is
acceptable. DO NOT ADD OIL.
• If the oil level is below the MIN mark, add enough oil to raise the level
within the MIN—MAX range.
• Oil levels above the MAX mark
may cause engine damage. Some
oil must be removed from the
engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.

Cleaner air
Ford endorses the use of reformulated“cleaner-burning ”gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
• Your Service engine soon indicator may come on. For more
information on the Service engine soon indicator, refer to the
Instrument cluster chapter.
Fuel Filter
For fuel filter replacement, see your dealer or a qualified service
technician. Refer to the scheduled maintenance guide chapter for the
appropriate intervals for changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles (1,600
km) of driving (engine break-in period). You will get a more accurate
measurement after 2,000 miles-3,000 miles (3,000 km –5,000 km).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in the Refill capacities
section of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the

detected a malfunction. Temporary malfunctions may cause yourCheck
engine/Service engine soon light to illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel. After three driving cycles without these or any
other temporary malfunctions present, the Check engine/Service engine
soon light should turn off. (A driving cycle consists of a cold engine
startup followed by mixed city/highway driving.) No additional vehicle
service is required.
If the Check engine/Service engine soon light remains on, have your
vehicle serviced at the first available opportunity.
Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your Check engine/Service engine
soon light is on, refer to the description in the Warning lights and
chimes section of the Instrument Cluster chapter. Your vehicle may not
pass the I/M test with the Check engine/Service engine soon light on.
If the vehicle ’s powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a “not ready for I/M test ”
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
• First, at least 10 minutes of driving on an expressway or highway.
• Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
CHECKING AND ADDING POWER STEERING FLUID
Check the power steering fluid. Refer to the scheduled maintenance
guide for the service interval schedules. If adding fluid is necessary,
use only MERCON AT F .
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
