ENGINE OIL
Checking the engine oil
Check the engine oil each time you fuel your vehicle.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. 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.
²If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.
MAX MIN
Maintenance and care
110

²If the oil level is below the MIN
mark, add enough oil to raise the
level within the MIN-MAX range.
²Oil 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 MIN and MAX ranges, 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.
3. Recheck the engine oil level. Make sure the oil level is not above the
MAX mark on the dipstick.
Engine oil and filter recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Maintenance and care
111

Do not use supplemental engine oil additives, oil treatments or engine
treatments. They are unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the ªService Guideº.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
Changing the engine oil and filter
Change your engine oil and filter according to the appropriate schedule
listed in the ªService Guideº.
Ford production and aftermarket (Motorcraft) oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, startup
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and
refilled as needed at least once each
year:
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
Maintenance and care
112

4. Use one of the following equations to calculate fuel economy.
Liters used x 1004Total kilometers traveled
Total miles traveled4Total gallons used
Keep a record for at least one month. This will provide an accurate
estimate of the vehicle's fuel economy.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
²Have the items listed in your ªService Guideº performed according to
the specified schedule.
The scheduled maintenance items listed in the ªService Guideº are
essential to the life and performance of your vehicle and to its emissions
system.
If other than Ford, Motorcraft or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Lumination of the charging system warning light, ªCheck Engineº light or
the temperature warning light, fluid leaks, strange odors, smoke or loss
of oil pressure, could indicate that the emission control system is not
working properly.
Maintenance and care
131

EXTERIOR BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
²Headlamps
²Tail lamps
²Brakelamps
²High-mount brakelamp
²Turn signals
²Backup lamps
²License plate lamp
Do not remove lamp bulbs unless they will be replaced immediately. If a
bulb is removed for an extended period of time, contaminants may enter
the lamp housings and affect performance.
Replacing headlamp bulbs
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
To remove the headlamp bulb:
1. Make sure headlamp switch is in OFF position, then open the hood.
2. Remove the sight shield by turning the three knobs to the unlock
position.
3. Disengage the safety snap on the connector by pulling upward slightly
on the clip.
4. Release clip and disconnect the
electrical connector from the bulb.
