FUEL CONSUMPTION
Filling the Tank
The advertised capacity is 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 amount of fuel in the tank after the fuel gauge indicates empty.
Note: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.
For consistent results when filling the fuel tank:
•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 three to five 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 as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of the vehicle’s fuel

LOAD LIMIT
Vehicle Loading – With and Without a Trailer
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Safety Compliance Certification Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight– is the weight of your new vehicle when you
picked it up from your authorized dealer plus any aftermarket
equipment.
Payload– is the combined weight of cargo and passengers that the
vehicle is carrying. Look for“THE COMBINED WEIGHT OF
OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX kg OR
XXX lb.”for maximum payload.
WARNING:The appropriate loading capacity of your vehicle can
be limited either by volume capacity (how much space is
available) or by payload capacity (how much weight the vehicle should
carry). Once you have reached the maximum payload of your vehicle,
do not add more cargo, even if there is space available. Overloading or
improperly loading your vehicle can contribute to loss of vehicle control
and vehicle rollover.

1Ford recommends using Motorcraft (Ford) DOT 4 LV High Performance 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.2Add the coolant type originally equipped in your vehicle.3Use of synthetic or synthetic blend motor oil is not mandatory. Your engine has been designed
to use 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.4Do not use supplemental engine oil additives in your engine. They are unnecessary and could
lead to engine damage that is not covered by your Ford warranty.5Do not use API S category oils labeled as SN, SM, SL or lower category unless the label also
display the API certification mark. These oils do not meet the requirements of the engine and
emission systems.6Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.7See your authorized dealer for fluid level checking or filling.8Fill Dana rear axles to 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.9Optional fuel tank 55.0 gallons (208.0L).10
