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
bulb works. If any light remains on after starting the vehicle, have the
respective system inspected immediately.
Emission system/Check engine:
TheCheck Engineindicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb. 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.
Check fuel cap:Illuminates when
the fuel cap may not be properly
installed. Continued driving with
this light on may cause the Emission
system/Check engine warning light
to come on. Refer toFuel Filler Capin theMaintenance and
Specificationschapter.

Engine oil pressure:Illuminates
when the oil pressure falls below the
normal range, refer toEngine oilin
theMaintenance and
Specificationschapter.
Engine coolant temperature:
Illuminates when the engine coolant
temperature is high. Stop the
vehicle as soon as possible, switch off the engine and let cool. Refer to
Engine coolantin theMaintenance and Specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot.
Transmission PRNDL indicator:
Displays the gearshift positions. If
an“E”character is displayed or
flashing, this indicates a
transmission malfunction, contact your dealer immediately. Operating the
transmission with the“E”character illuminated may cause additional
damage to the transmission.
Traction Control
active:
Illuminates when the Traction
Control
is active. If the light
remains on, have the system
serviced immediately, refer to theDrivingchapter for more information.
Low fuel:Illuminates when the fuel
level in the fuel tank is at or near
empty (refer toFuel gaugein this
chapter).

5. Turn the ignition back to the 4 (RUN) position. The horn will chirp.
6. Press the unlock control, then press the lock control. The horn will
chirp once if autolock was deactivated or twice (one short and one long
chirp) if autolock was activated.
7. Turn the ignition to the 1 (LOCK) or 2 (OFF) position.
SECURILOCKPASSIVE ANTI-THEFT SYSTEM
SecuriLock
passive anti-theft system is an engine immobilization
system. This system is designed to help prevent the engine from being
started unless acoded key programmed to your vehicleis used. The
SecuriLock
passive anti-theft system is not compatible with non-Ford
aftermarket remote start systems. Use of these systems may result in
vehicle starting problems and a loss of security protection.
Theft indicator
The theft indicator is the flashing red indicator located on top of the
instrument panel.
•When the ignition is in the 2 (OFF) position, the indicator will flash
once every 2 seconds if the vehicle is locked and the perimeter alarm
is armed.
•When the ignition is in the 4 (RUN) position, the indicator will glow
for 3 seconds 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 4 (RUN) position. If
this occurs, the vehicle should be taken to an authorized dealer for
service.
Automatic arming
The vehicle is armed immediately
after switching the ignition to the 1
(LOCK) or 2 (OFF) position.

Automatic disarming
Switching the ignition to the 4 (RUN) position with acoded keydisarms
the vehicle.
•The theft indicator will illuminate for three seconds and then go out.
•If the theft indicator stays on for an extended period of time or
flashes rapidly, have the system serviced by your dealer.
Key information
Your vehicle is supplied withtwo coded keys (or three keys, if the
valet feature is available).Only acoded keywill start your vehicle.
Spare coded keys may be purchased from an authorized Ford dealer. An
authorized Ford dealer can also program yourcoded key,or you can do
it yourself. Refer toProgramming spare keysin this chapter.
The following items may prevent the vehicle from starting:
•Large metallic objects.
•Electronic devices on the key chain that can be used to purchase
gasoline or similar items.
•A second key on the same key ring as thecoded key.
If any of these items are present, you need to prevent these objects from
touching thecoded keywhile starting the engine. These objects cannot
damage thecoded key,but may cause a momentary“no start”condition
if they are too close to the key when starting the engine. If a problem
occurs, turn the ignition to the 2 (OFF) position and restart the engine
with all other objects on the key ring held away from the ignition key.
Check to make sure thecoded keyis an approved Fordcoded key.
If your keys are lost or stolen, you will need to do the following:
•Use your spare key to start the vehicle, or
•Have your vehicle towed to an authorized Ford dealer or a locksmith.
The key codes will need to be erased from your vehicle and new
codes will need to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correctcoded keymust be used for your vehicle. The use of the
wrongcoded keymay lead to a“no start”condition.
If an unprogrammed key is used in the ignition, it will cause a
“no start”condition.

surface, try switching the Traction Control
system off. This may allow
excess wheel spin to“dig”the vehicle out and enable a successful
“rocking”maneuver.
If the Traction Control
system is cycled excessively, the brake portion
of the system will shut down to prevent the rear brakes from
overheating. A limited Traction Control
function using only engine
torque reduction will still help control wheels from over-spinning. When
the rear brakes have cooled down, the system will again function
normally. Anti-lock braking is not affected by this condition and will
function normally during the cool down period.
If a system fault is detected, the traction control switch’s OFF indicator
will illuminate and your vehicle should be serviced.
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 a Traction 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.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween the MIN and 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.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
2. If the engine oil level is not within the normal range, add only certified
engine oil of the recommended viscosity. Remove the engine oil filler cap
and use a funnel to pour the engine oil into the opening.

Many of the world’s automakers approved the World-wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-wide Fuel Charter.
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“Check Engine”indicator may come on. For more information on
the“Check Engine”indicator, refer to theInstrument Cluster
chapter.
Fuel Filter
For fuel filter replacement, see your dealer or a qualified service
technician. Refer to the scheduled maintenance guide 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).

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.
POWER STEERING FLUID
Refer to the scheduled maintenance guide for the service interval
schedules. If adding fluid is necessary, use only MERCONAT 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).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the
reservoir. It should be between the
MIN and MAX lines. Do not add
fluid if the level is in this range.
5. If the fluid is low, add fluid in
small amounts, continuously
checking the level until it reaches
the range between the MIN and
MAX lines. Be sure to put the cap
back on the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels between the“MIN”and
“MAX”lines are within the normal
operating range; there is no need to
add fluid. If the fluid levels are
outside of the normal operating range the performance of your brake
system could be compromised; seek service from your dealer
immediately.
