Replacing headlamp bulbs
To remove the headlamp bulb:
1. Make sure headlamp switch is in
OFF position.
2. Remove the protective bulb cover
by loosening and removing the five
screws.
3. Rotate the light bulb socket
counter clockwise and pull it
straight out from the assembly.
4. Remove the old bulb from the
lamp assembly by pulling it straight
out of the bulb socket.
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.
5. To complete installation, follow the removal procedure in reverse
order.
Note:To ensure a good seal, attach the bulb cap and partially tighten
the screws. Check to ensure the gasket is fully centered. Finish
tightening the screws in a criss-cross pattern (upper-left, lower right
etc.)
Replacing HID headlamp bulbs (if equipped)
The low beam headlamps on your vehicle use a“high intensity discharge”
source. These lamps operate at a high voltage. When the bulb is burned
out, the bulb and starter capsule assembly must be replaced by your
dealer or a qualified technician.
Replacing front parking lamp/turn signal bulbs
The park/turn lamp bulbs can be replaced with out removing the
headlamp assembly.
1. Make sure headlamp switch is in OFF position, then open the hood.
2. Remove the protective bulb cover by removing the three retaining
bolts.

WINDSHIELD WASHER FLUID
Windshield washer fluid
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specifications. Refer toRefill
capacitiesin this chapter.
State or local regulations on volatile
organic compounds may restrict the
use of methanol, a common
windshield washer antifreeze
additive. Washer fluids containing non-methanol antifreeze agents should
be used only if they provide cold weather protection without damaging
the vehicle’s paint finish, wiper blades or washer system.
If you operate your vehicle in temperatures below 4.5°C (40°
F), use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
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 up to 10 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.

•If required, add engine oil to the
engine. Refer toAdding engine
oilin this chapter.
•Do not overfill the engine
with oil. Oil levels above this
mark may cause engine
damage.If the engine is
overfilled, some oil must be
removed from the engine by a
qualified 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 operating 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.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level indicator and/or the engine oil filler cap removed.

•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36°C (-34°F). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014–R1060). The level of coolant
should be maintained at the“cold full”of“cold fill range”level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50–50 mixture of coolant and water provides the following:
•Freeze protection down to -36°C (-34°F).
•Boiling protection up to 129°C (265°F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
