Battery voltage gauge
This gauge shows the
battery voltage when
the ignition is in the
ON position. If the
pointer moves and stays outside the normal
operating range (as indicated), have the vehicle's
electrical system checked as soon as possible.
Engine oil pressure gauge
This shows the engine
oil pressure in the
system. Sufficient
pressure exists as long
as the needle remains in the normal range (the area
between the ªLº and ªHº).
If the gauge indicates low pressure, stop the vehicle
as soon as safely possible and switch off the engine
immediately. Check the oil level. Add oil if needed
(refer toEngine oilin theMaintenance and care
chapter). If the oil level is correct, have your vehicle
checked at your dealership or by a qualified
technician.

²If the oil level is
below the MIN mark,
add enough oil to
raise the level within
the MINÐMAX
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 to
Checking the engine oilin this chapter.
2. If the engine oil level is not within the normal
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 MAX mark 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.

Engine oil and filter recommendations
Look for this
Certification
Trademark.
Use SAE 5W-30 motor oil certified for gasoline
engines by the American Petroleum Institute (API).
Motor oil displaying the API Certification Trademark
will meet all requirements for your vehicle's engine.
Ford oil specification is WSS-M2C153-G.
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:
Maintenance and care
137

²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
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.
²Using 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 on 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.
Maintenance and care
167

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,
ªService Engine Soonº 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.
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 ªCheck Engine/Service Engine Soonº light is
on, refer to the description in theWarning Lights
and Chimessection of theInstrumentation
chapter. Your vehicle may not pass the I/M test with
the ªCheck Engine/Service Engine Soonº light on.
