•
Turn the ignition off before fueling; an
inaccurate reading results if the engine
is left running.
• Use the same fill rate
(low-medium-high) each time the tank
is filled.
• Allow no more than two automatic
click-offs when filling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the
first 1000 miles (1600 kilometers) of
driving (this is your engine ’s break-in
period); a more accurate measurement is
obtained after 2000 miles - 3000 miles
(3200 kilometers - 4800 kilometers). Also,
fuel expense, frequency of fill ups or fuel
gauge readings are not accurate ways to
measure fuel economy.
1. Fill the fuel tank completely and record
the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least 3 to 5 tank fill ups, fill the
fuel tank and record the current
odometer reading.
4. Subtract your initial odometer reading from the current odometer reading.
5. Calculate fuel economy by dividing miles traveled by gallons used (For
Metric: Multiply liters used by 100, then
divide by kilometers traveled).
Keep a record for at least 1 month and
record the type of driving (city or highway).
This provides an accurate estimate of the
vehicle ’s fuel economy under current
driving conditions. Additionally, keeping
records during summer and winter show
how temperature impacts fuel economy.
In general, lower temperatures mean lower
fuel economy. Conditions
•
Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Carrying unnecessary weight may
reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400
pounds [180 kilograms] of weight
carried).
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars/light bars, running boards, ski
racks) may reduce fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 8– 10
miles (12 –16 kilometers) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Close windows for high speed driving.
EMISSION CONTROL SYSTEM WARNINGS
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. Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes. 144

BRAKE FLUID CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating range;
there is no need to add fluid. If the fluid
levels are outside of the normal operating
range, the performance of the system
could be compromised; seek service from
your authorized dealer immediately.
POWER STEERING FLUID
CHECK
3.5L, 3.7L and 5.0L Engines
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
6.2L Engines
Check the power steering fluid. Refer to
See Scheduled Maintenance (page 438).
1. Start the engine and let it run until it reaches normal operating temperature
(the engine coolant temperature gauge
indicator will be near the center of the
normal area between
H and C).
2. While the engine idles, turn the steering
wheel left and right several times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN and MAX
lines. Do not add fluid if the level is in
this range.
5. If the fluid is low, add fluid in small amounts, continuously checking the
level until it reaches the range between
the MIN and MAX lines. For the proper
fluid type, See
Capacities and
Specifications (page 296).
6. Put the cap back on the reservoir. WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), 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. Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 296).
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.
FUEL FILTER
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.
CHANGING THE 12V BATTERY WARNINGS
Batteries normally produce explosive
gases that can cause personal injury.
Therefore, do not allow flames,
sparks or lighted substances to come near
the battery. When working near the
battery, always shield your face and
protect your eyes. Always provide proper
ventilation.

1
Ford recommends using Motorcraft (Ford) DOT 4 LV High Performance Motor Vehicle
Brake Fluid or equivalent meeting WSS-M6C65-A2. Use of any fluid other than the
recommended fluid may cause degraded brake performance and not meet the Ford
performance standards. Keep brake fluid clean and dry. Contamination with dirt, water,
petroleum products or other materials may result in brake system damage and possible
failure.
2 The design of your engine allows for the use of Motorcraft engine oils or equivalent oils
that meet Ford specifications. It is also acceptable to use an engine oil of recommended
viscosity grade that meets API SN requirements and displays the API certification mark
for gasoline engines.
3 Do not use supplemental engine oil additives in your engine. They are unnecessary and
could lead to engine damage not covered by your Ford warranty.
Do not use API S category oils labeled as SN, SM, SL or lower category unless the label
also displays the API certification mark. These oils do not meet the requirements of the
engine and emission system.
4 Add the coolant type originally equipped in your vehicle.
5 Service refill capacity is determined by filling the axle to 1/4-9/16 inch (6-14 millimeter)
below the bottom of the filler hole with the vehicle on a level surface. Add 4 fl oz. (118
milliliters) of Additive Friction Modifier XL-3 (US) / CXL-3 (Canada) or equivalent meeting
Ford specification EST-M2C118-A, for complete fill of 8.8-inch Traction-Lok axles.
6 Filled with a synthetic rear axle lubricant, consider the rear axle on your vehicle filled for
life. You do not need to check or change the rear axle lubricant unless you suspect a leak.
Change the rear axle lubricant any time you have submerged the rear axle in water.
7 Service refill capacity is determined by filling the transfer case to the bottom of the filler
hole with the vehicle on a level surface.
8 Make sure the correct automatic transmission fluid is used. Transmission fluid
requirements are indicated on the dipstick blade or the dipstick handle. Before adding,
check the container to verify the fluid is of the correct type. Refer to your scheduled
maintenance information to determine the correct service interval.
Note: Automatic transmissions that require MERCON LV should only use MERCON LV fluid.
Use of any fluid other than the recommended fluid may cause transmission damage.
9 Indicates only approximate dry-fill capacity. Some applications may vary based on cooler
size and if equipped with an in-tank cooler. Use the indication on the dipstick, showing
the normal operating range, to determine the amount of transmission fluid and the fluid
level.
10 See the Warning below: WARNING
The air conditioning refrigerant system contains refrigerant R-134a under high
pressure. Opening the air conditioning refrigerant system can cause personal injury.
Have the air conditioning refrigerant system serviced only by qualified personnel.
