²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.
WHAT YOU SHOULD KNOW ABOUT
AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in
an overfilled tank may cause leakage and
lead to fuel spray and fire.
The fuel system may be under pressure. If
the fuel filler cap is venting vapor or if you
hear a hissing sound, wait until it stops before
completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel
tank may damage the fuel system or cause the fuel
cap to disengage in a collision, which may result in
possible personal injury.
Automotive fuels can cause serious injury or
death if misused or mishandled.
Gasoline may contain benzene, which is a
cancer-causing agent.
Maintenance and care

soap and water. Consult a physician immediately
if you experience an adverse reaction.
When refueling always shut the engine off
and never allow sparks or open flames near
the filler neck. Never smoke while refueling. Fuel
vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling
excess fumes.
The flow of fuel through a fuel pump nozzle
can produce static electricity, which can
cause a fire if fuel is pumped into an ungrounded
fuel container.
Use the following guidelines to avoid static build-up
when filling an ungrounded fuel container:
²Place approved fuel container on the ground.
²DO NOT fill a fuel container while it is in the
vehicle.
²Keep the fuel pump nozzle in contact with the
fuel container while filling.
²DO NOT use a device that would hold the fuel
pump handle in the fill position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with
a 1/8 turn on/off feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8
of a turn until it stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with
the notches on the filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it
stops.
Maintenance and care
182

ªCheck Fuel Capº illuminates when the ignition is
turned to the ON position to ensure your bulb is
working. When this light turns on, check the fuel
filler cap. Continuing to operate the vehicle with the
Check Fuel Cap light on, can activate the Service
Engine Soon warning. When the fuel filler cap is
properly re-installed, the light(s) will turn off after a
period of normal driving.It may take a long
period of time for the system to detect an
improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace
it with a fuel filler cap that is designed for
your vehicle. The customer warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If
the fuel filler cap is venting vapor or if you
hear a hissing sound, wait until it stops before
completely removing the fuel filler cap. Otherwise,
fuel may spray out and injure you or others.
If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel
tank may damage the fuel system or cause the fuel
cap to disengage in a collision, which may result in
possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel
is prohibited by law and could damage your vehicle.
Do not use fuel containing methanol. It can damage
critical fuel system components.
Your vehicle was not designed to use fuel or fuel
additives with metallic compounds, including
manganese-based compounds containing MMT.
Maintenance and care
183

Replace the fuel filter with an authorized
Motorcraft part. The customer warranty may
be void for any damage to the fuel system if an
authorized Motorcraft fuel filter is not used.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel
economy is you, the driver. You must gather
information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel
gauge readings are NOT accurate as a measure of
fuel economy. We do not recommend taking fuel
economy measurements during the first 1 600 km
(1 000 miles) of driving (engine break-in period).
You will get a more accurate measurement after
3 000 km±5 000 km (2 000 miles-3 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your
vehicle is equal to the rated refill capacity of the fuel
tank as listed in theRefill capacitiessection ofthe
Capacities and specificationschapter.
The advertised capacity is the amount of the
indicated capacity and the empty reserve combined.
Indicated capacity is the difference in the amount of
fuel in a full tank and a tank when the fuel gauge
indicates empty. Empty reserve is the small amount
of fuel remaining in the fuel tank after the fuel
gauge indicates empty.
The amount of usable fuel in the empty reserve
varies and should not be relied upon to
increase driving range. When refueling your
vehicle after the fuel gauge indicates empty,
you might not be able to refuel the full amount
of the advertised capacity of the fuel tank due
to the empty reserve still present in the tank.

1Add the coolant type originally equipped in your vehicle.2Rear axle lubricants do not need to be checked or
changed unless a leak is suspected, service is required or
the axle assembly has been submerged in water. The axle
lubricant should be changed any time the rear axle has
been submerged in water. Fill 6 mm to 14 mm (1/4 inch to
9/16 inch) below bottom of fill hole. Add 118 ml (4 oz.) of
Additive Friction Modifier C8AZ-19B546-A or equivalent
meeting Ford specification EST-M2C118±A for complete
refill of Traction-Lok axles.
3Ensure the correct automatic transmission fluid is used.
Transmission fluid requirements are indicated on the
dipstick or on the dipstick handle. MERCONtand

MERCONtand MERCONtV. Refer to your scheduled
maintenance guide to determine the correct service
interval.
4Indicates only approximate dry-fill capacity. Some
applications may vary based on cooler size and if equipped
with an in-tank cooler. The amount of transmission fluid
and fluid level should be set by the indication on the
dipstick's normal operating range.

5Service refill capacity is determined by filling the
transmission to the bottom of the filler hole with the
