Spare tire information
Note:If your vehicle is equipped the tire pressure monitoring system
(TPMS), the system indicator light will illuminate when the spare is in
use. To restore the full functionality of the TPMS system, all road wheels
equipped with the tire pressure monitoring sensors must be mounted on
the vehicle.
If your vehicle is equipped with TPMS, have a flat tire serviced by an
authorized dealer in order to prevent damage to the TPMS sensor; refer
toTire Pressure Monitoring System (TPMS)in theTires, Wheel and
Loadingchapter. Replace the spare tire with the road tire as soon as
possible.
Stopping and securing the vehicle
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite to the tire being
changed.
Refer to the instruction sheet (located under the jack tool kit) for
detailed tire change instructions.
Park on a level surface, activate
hazard flashers and set the parking
brake.
•Automatic transmission: Place
gearshift lever in P (Park).
•Manual or electronic shift 4x4:
Place transfer case in 4H or 4L.

If equipped with a tether, perform the following additional steps:
6. Lift the spare tire on end to
access the tether attachment.
7. Use the lug wrench to remove the
lug nut from the spare tire tether.
8. If not replacing the spare or flat
tire to the underbody storage area,
raise the wheel retainer up into the
installed position.
9. Use the attached fastener strap
(on the spare tire tether) to attach
the tether end to the winch retainer prior to raising to the installed
position.
Tire change procedure
WARNING:When one of the rear wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission is in P (Park).
WARNING:To prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other side and
end of the vehicle) to the tire being changed.
WARNING:If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
Note:Passengers should not remain in the vehicle when the vehicle is
being jacked.

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.
Preparing your vehicle
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 have firm and/or 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.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.

Note:Towing an ESOF 4x4 vehicle with the front wheels on the ground
without disengaging the front hubs may cause damage to the automatic
transmission.
Note:Towing a 4x2 or an ESOF 4x4 vehicle with the rear wheels on the
ground for more than 50 miles (80 km) and/or in excess of 35 mph
(56 km/h) may cause damage to the automatic transmission.
Note:On Dual Rear Wheel (DRW) vehicles, an outer rear wheel must be
removed prior to using a wheel lift wrecker.
Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Emergency towing
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer, or flatbed transport vehicle) your
vehicle (regardless of transmission powertrain configuration) can be flat
towed (all wheels on the ground) under the following conditions:
•Vehicle is facing forward so that it is being towed in a forward
direction.
•Place the transmission in N (Neutral). Refer toBrake-shift interlock
in theDrivingchapter for specific instructions if you cannot move the
gear shift lever into N (Neutral).
•Maximum speed is not to exceed 35 mph (56 km/h).
•Maximum distance is 50 miles (80 km).

•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
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 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) 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.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EMISSION CONTROL SYSTEM
WARNING: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.
WARNING:Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
