•A final example for your vehicle with 1400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100
lb. (45 kg) bags of cement. Do you have enough load capacity to
transport the cement to your home? If you and your friend each weigh
220 lb. (99 kg), the calculation would be: 1400 – (2 x 220) –
(12 x 100) = 1400 – 440 – 1200 = – 240 lb. No, you do not have
enough cargo capacity to carry that much weight. In metric units, the
calculation would be: 635 kg — (2 x 99 kg) — (12 x 45 kg) = 635 —
198 — 540 = —103 kg. You will need to reduce the load weight by at
least 240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags,
then the load calculation would be:
1400 – (2 x 220) – (9 x 100) = 1400 – 440 – 900 = 60 lb. Now you
have the load capacity to transport the cement and your friend home.
In metric units, the calculation would be: 635 kg — (2 x 99 kg) —
(9 x 45 kg) = 635 — 198 — 405 = 32 kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
theDrivingchapter of this owner guide.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling cargo and people may raise the center of gravity of the vehicle.
TRAILER TOWING
Trailer towing puts additional loads on your vehicle’s engine, transmission,
axle, brakes, tires, and suspension. For your safety and to maximize vehicle
performance, be sure to use the proper equipment while towing.

1Add the coolant type originally equipped in your vehicle.2Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the
requirements of Ford specification WSS-M2C930-A and the API Certification mark.3Indicates only approximate dry-fill capacity. Some applications may vary based on cooler size and
if equipped with an in-tank cooler.4Automatic transmissions that require MERCONSP should only use MERCONSP fluid. Use of a
dual usage fluid in an automatic transmission requiring MERCONSP may cause transmission
damage. Refer toscheduled maintenance informationto determine the correct service interval.
Use of any fluid other than the recommended fluid may cause transmission damage.5Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is considered lubricated
for life. These lubricants are not to be checked or changed unless a leak is suspected, service is
required or the axle has been submerged in water. The axle lubricant should be changed any time
the axle has been submerged in water.
