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 also lists engine displacement.
Please consult your warranty information for complete emission warranty
information.
On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects
the environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle.
When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. SeeEasy Fuel®
No Cap Fuel Systemin this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine start-up followed by mixed city or highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle serviced
at the first available opportunity. Although some malfunctions detected by
the OBD-II may not have symptoms that are apparent, continued driving
with the service engine soon indicator on can result in increased emissions,
lower fuel economy, reduced engine and transmission smoothness, and can
lead to more costly repairs.

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
Tire Label or 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. The maximum payload for your vehicle can be found
on the Tire Label on the B-Pillar or the edge of the driver’s door (vehicles
exported outside the US and Canada may not have a Tire Label). Look for
“THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD
NEVER EXCEED XXX kg OR XXX lb.”for maximum payload. The
payload listed on the Tire Label is the maximum payload for the vehicle
as built by the assembly plant. If any aftermarket or authorized-dealer
installed equipment has been installed on the vehicle, the weight of the
equipment must be subtracted from the payload listed on the Tire Label in
order to determine the new payload.

FUEL CUT-OFF SWITCH
WARNING:Failure to inspect and if necessary repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected by
an authorized dealer after any collision.
In the event of a moderate to severe collision, this vehicle is equipped
with a fuel pump shut-off feature that stops the flow of fuel to the
engine. Not every impact will cause a shut-off.
Should your vehicle shut off after a collision, you may restart your
vehicle by doing the following:
1. Turn the ignition off and wait approximately 10 seconds.
2. Turn the ignition on.
3. Repeat steps 1 and 2 to re-enable the fuel pump.
JUMP-STARTING THE VEHICLE
WARNING:The gases around the battery can explode if exposed
to flames, sparks, or lit cigarettes. An explosion could result in
injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission vehicle.
Automatic transmissions do not have push-start capability. Attempting
to push-start a vehicle with an automatic transmission may cause
transmission damage.
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may exhibit a combination of firm and soft shifts. This
operation is considered normal and will not affect function or durability
of the transmission. Over time, the adaptive learning process will fully
update transmission operation.

Preparing Your Vehicle
Note:Use only a 12–volt supply to start your vehicle.
Note:Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
2. Check all battery terminals. Remove the positive terminal cover
(if equipped) and any excessive corrosion before you attach the battery
cables. Ensure that vent caps are tight and level.
3. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the Jumper Cables
WARNING:Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
Note:Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.

Adding Engine Oil
Note:Do not remove the filler cap when the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine
and emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets Ford specifications. SeeCapacities and
Specificationsfor more information.
3. Replace the filler cap. Turn it until you feel a strong resistance.
ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed inScheduled Maintenance Information.
Note:Make sure that the level is at the FULL COLD level or within the
COLD FILL RANGE in the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
COLD FILL RANGE.
If the level is below the COLD FILL RANGE, add coolant immediately.
SeeAdding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%,
which equates to a freeze point between -30°F (-34°C) and -34°F
(-37°C).
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.

BRAKE AND CLUTCH FLUID CHECK
Brake and clutch (if equipped) systems are supplied from the same
reservoir.
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
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill.
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.
For Shelby fuel filter requirements, see theShelby GT500 Supplement.
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 the technical specifications chart in
theCapacities and Specificationschapter.
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.
