WARNING LIGHTS AND CHIMES
Base instrument cluster
Optional instrument cluster
Mach 1 instrument cluster
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.

Service engine soon:
TheService engine
soonindicator 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 Specificationschapter. 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
Service engine soon light to come on. Refer toFuel
filler capin theMaintenance and Specifications
chapter.

confirm the brake
system warning light is
functional, it will momentarily illuminate when the
ignition is turned to the ON position when the

and START, 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

Parking brake
To set the parking
brake (1), pull the
parking brake handle
up as far as possible.
The BRAKE warning
lamp will illuminate and
will remain illuminated
until the parking brake
is released.
To release, press and hold the button (2), pull the
handle up slightly, then push the handle down.
Always set the parking brake fully and make
sure that the gearshift is securely latched in
P (Park) (automatic transmission) or in 1 (First)
(manual transmission).
If the parking brake is fully released, but the
brake warning lamp remains illuminated, the
brakes may not be working properly. See your
dealer or a qualified service technician.
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

Do not park your vehicle in Neutral, it may
move unexpectedly and injure someone. Use
1 (First) gear and set the parking brake fully.
Removing the key
Turn the ignition off,
push the release lever
(located above the
ignition), then turn the
key toward you and
remove the key.
DRIVING THROUGH WATER
Do not drive quickly through standing water,
especially if the depth is unknown. Traction or brake
capability may be limited and if the ignition system
gets wet, your engine may stall. Water may also
enter your engine’s air intake and severely damage
your engine.
If driving through deep or standing water is
unavoidable, proceed very slowly. Never drive
through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims
(for cars).
Once through the water, always try the brakes. Wet
brakes do not stop the vehicle as effectively as dry
brakes. Drying can be improved by moving your
vehicle slowly while applying light pressure on the
brake pedal.
Driving through deep water where the
transmission vent tube is submerged may allow
water into the transmission and cause internal
transmission damage. Have the fluid checked
and, if water is found, replace the fluid.

the left side of the
trunk between the left
rear tail light and the
trunk liner, and to the
left of the hole in the
trunk liner
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the switch by
pushing in on the reset button.

•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the
vehicle (including the cargo area).
•Keep the fuel pump nozzle in contact with the
fuel container while filling.
•DO NOT use a device that would hold the fuel
pump handle in the fill position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a 1/8 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.

turned to the ON position to ensure your bulb is
working. When this light turns on, check the fuel
filler cap. Continuing to operate the vehicle with the
Check Fuel Cap light on, can activate the Service
Engine Soon warning. When the fuel filler cap is
properly re-installed, the light(s) will turn off after a
period of normal driving.It may take a long
period of time for the system to detect an
improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace

your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft fuel filler cap is not used.

On board diagnostics (OBD-II)
Your vehicle is equipped with a computer that
monitors the engine’s emission control system. This
system is commonly known as the On Board
Diagnostics System (OBD-II). This OBD-II system
protects the environment by ensuring that your
vehicle continues to meet government emission
standards. The OBD-II system also assists the
service technician in properly servicing your vehicle.
When theCheck Engine/Service Engine Soonlight
illuminates, the OBD-II system has detected a
malfunction. Temporary malfunctions may cause
yourCheck Engine/Service Engine Soonlight 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.
3. The fuel cap may not have been securely
tightened.
These temporary malfunctions can be corrected by
filling the fuel tank with good quality fuel and/or
properly tightening the fuel cap. After three driving
cycles without these or any other temporary
malfunctions present, theCheck Engine/Service
Engine Soonlight 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 theCheck Engine/Service Engine Soonlight
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 theWarning lights
and chimessection of theInstrument cluster
chapter. Your vehicle may not pass the I/M test with
the“Check Engine/Service Engine Soon”light on.
