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.
Check engine:TheCheck Engine
indicator 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 toOn
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 (if equipped):
Illuminates when the fuel cap may
not be properly installed. Continued
driving with this light on may cause
the 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 recovery 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 and may cause damage to your transmission.
Contact your dealer immediately.
AdvanceTrac
(if equipped):
Illuminates when the AdvanceTrac

system is active. If the light remains
on, have the system serviced
immediately, refer to theDriving
chapter for more information.

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 top of the instrument panel.
•When the ignition is in the ON 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 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 no previously programmed coded keys are available, you must take
your vehicle to your dealer to have the spare key(s) programmed.
Locks and Security

TheTraction Control
switch,
located on the center console by the
gearshift lever, has an indicator light
that illuminates when the system is
off. The Traction Control
system
will automatically turn on every time
the ignition is turned off and on.
If you should become stuck in snow
or ice or on a very slippery road
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 a system fault is detected, the traction control switch’s OFF indicator
will illuminate and your vehicle should be serviced.
AdvanceTracStability Enhancement System (if equipped)
The AdvanceTrac
system provides a stability enhancement feature as
well as a traction enhancement feature. It helps your vehicle maintain
traction, when driving on slippery and/or hilly road surfaces, by detecting
and controlling wheel spin. Excessive wheel spin is controlled by
momentarily reducing engine power and rapidly applying the anti-lock
brakes. The system is a driver aid which makes your vehicle easier to
handle primarily on snow and ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
system off by pressing the AdvanceTrac
button.
This will allow your tires to“dig”for traction.
If the AdvanceTrac
system is activated excessively in a short period of
time, the brake portion of the system will shut down to allow the brakes
to cool down. A limited AdvanceTrac
function using only engine power
reduction will still help control the wheels from over-spinning. When the
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.
AdvanceTrac
enhances your vehicle’s stability during maneuvers that
require all available tire traction, like in wet/snowy/icy road conditions
and/or when performing emergency maneuvers. In an emergency
lane-change, the driver will experience better overall vehicle traction,
and have better control of the vehicle.
The AdvanceTrac
system helps the driver maintain steering control if
the vehicle begins to slide excessively left or right or spin out.
Driving

AdvanceTrac
willattempt to correct the sliding motion by applying
brake force at individual tires and, if necessary, by reducing engine
power.
Driving conditions which may activate AdvanceTrac
include:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Hitting a patch of ice
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Hitting a curb while turning
•Driving on slick surfaces
•Cornering while towing a heavily loaded trailer (refer toTrailer
Towingin this chapter)
The AdvanceTrac
system automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse); the ABS and traction enhancement features will
continue to function.
The AdvanceTrac
button allows
the driver to control the availability
of the AdvanceTrac
system.
AdvanceTrac
system status is
indicated by a warning indicator
light with a“sliding car”icon in the
instrument cluster that will flash
when the system is active and an
indicator light in the control button
that will illuminate when the system
is turned off. In vehicles with a
message center, the message“ADVANCETRAC OFF”will be displayed.
If a failure is detected in the AdvanceTrac
system, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the control once will disable the AdvanceTrac
stability
enhancement and the engine power reduction portion of the traction

•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.
Maintenance and Specifications

It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world’s automakers
issued 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. In Canada,
look for fuels that display theAuto
Makers’Choice
logo.
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

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.
TRANSMISSION FLUID
