ENGINE OIL
Checking the engine oil
Refer to the Scheduled Maintenance Guide for the appropriate intervals
for checking the engine oil .
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
139

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
140

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 Scheduled Maintenance Guide.
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. Refer to the
Scheduled Maintenance Guide for
the service interval schedules:
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.
MAX
Maintenance and care
141

²Use recommended engine oil. Refer toLubricant Specifications.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle Scheduled Maintenance Guide.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Use of fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving over hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of Km/L (MPG) expected on
the vehicle, depending upon the driver's method of operation and
conditions.
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:
Maintenance and care
164

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 Scheduled Maintenance Guide performed
according to the specified schedule.
The scheduled maintenance items listed in the Scheduled Maintenance
Guide 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.
Illumination of the charging system warning light,Check Engine
indicator 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.
Exhaust leaks may result in entry of harmful and potentially
lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted 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. This decal identifies engine displacement and gives some tune up
specifications.
Please consult your ªWarranty Guideº for complete emission warranty
information.

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 protective cover 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.
5. Remove the bulb retaining ring by
rotating it counterclockwise (when
viewed from the rear) about 1/8
turn to free it from the bulb socket,
and slide the ring off the plastic
base. Keep the ring to retain the
new bulb.
6. With out turning, remove the old bulb from the lamp assembly by
gently pulling it straight back out of the lamp assembly.
To install the new bulb:
1. With the flat side of the new
bulb's plastic base facing upward,
insert the glass end of the bulb into
the lamp assembly. Turn the bulb
left or right to align the grooves in
the plastic base with the tabs in the
lamp assembly. When the grooves are aligned, push the bulb into the
lamp assembly until the plastic base contacts the rear of the lamp
assembly.
