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:If this light
illuminates while driving, it is a
possible indication that one of the
engine’s emission control systems
has failed.
Check fuel cap: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.
Brake system warning light:
Illuminates if the parking brake is
engaged or to indicate low brake
fluid level. To confirm the brake
system warning light is functional, it
will momentarily illuminate when the ignition is turned to the ON
position (alternatively for some vehicles when the ignition is moved from
the ON position to the START position, the light will momentarily
illuminate prior to reaching the START position).

SAE 5W-30 engine oil recommendation
Use only oils“Certified For Gasoline
Engines”by the American
Petroleum Institute (API). Use
Motorcraft (Part: XO-5W30–QSP
U.S.) or an equivalent oil meeting
Ford Motor Company specification
WSS-M2C205–A. It is also
recommended that you use the
appropriate Motorcraft oil filter or
an equivalent filter meeting the
Ford Motor Company specification for your engine.
Change your engine oil and filter according to theScheduled
Maintenance Guide.
BATTERY
Your vehicle has a Motorcraft
maintenance-free battery that
normally does not require additional
water.
Check the battery electrolyte level
under severe usage. Refer to the
Scheduled Maintenance Guide.
If the level is low, add plain tap
water. If possible, use distilled
water. If the battery needs water
often, have the charging system checked.
Note:The electrolyte level in each cell should be at the“level indicator.”
Do not overfill the battery cells.
Keep the top of the battery clean and dry. Also, make certain the battery
cables are always tightly fastened to the terminals. If your battery has a
cover/shield, make sure it is reinstalled after cleaning or battery
replacement.
Batteries normally produce explosive gases which can cause
personal injury. Do not allow flames, sparks or lighted substances
to come near the battery. When working near the battery, always shield
your face and protect your eyes. Always provide proper ventilation.

The following signs could indicate a problem with your emission control
system:
•Fluid leaks
•Strange odors
•Smoke
•Loss of engine power
•Illumination of the charging system, temperature, or“Check Engine”
light in the instrument panel.
Exhaust leaks may result in harmful and potentially lethal fumes
entering the passenger compartment.
It is unlawful to intentionally remove an emission control device or
prevent it from working. Information about your vehicle’s emission
system is on the Vehicle Emission Control Information decal located on
or near the engine.
READINESS FOR INSPECTION/MAINTENANCE (I/M) TESTING
It may be a legal requirement in your area to pass an I/M test of the
on-board diagnostics system. If the system or battery has just been
serviced, the on-board diagnostic system is reset to a“not ready for I/M
test”condition. To ready the system, allow the vehicle to sit for at least
eight hours without starting. Then, start the engine and complete the
following driving cycle:
1. Drive on an expressway or highway for at least 10 minutes.
2. Drive in stop-and-go traffic for at least 20 minutes with a minimum of
four idle periods.
The engine must warm up to its normal operating temperature. Once
started, do not turn off the engine until the above drive cycle is
complete.
Note:If your“Check Engine”light is on, your vehicle may not pass an
I/M test.
