CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Tire change procedure
Preparing to change the tire
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.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park).

4. Apply the parking brake and turn
engine OFF.
5. Block the wheel that is diagonally
opposite the tire you are changing.
The parking brake is on the
transmission. Therefore, the vehicle
will not be prevented from moving
when a rear wheel is lifted, even if
the parking brake is applied. Be
sure to block both directions of the wheel that is diagonally opposite to
the wheel that is being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
6. Remove the spare tire and jack from the storage location.
7. Loosen the wheel nut by pulling up on the handle of the lug nut
wrench about one-half turn (counterclockwise). Do not remove the
wheel lug nuts until you raise the tire off the ground.
Replacing the tire
To lessen the risk of personal injury, do not put any part of your
body under the vehicle while changing a tire. Do not start the
engine when your vehicle is on the jack. The jack is only meant for
changing the tire.
8. Position the jack to raise the front or rear wheel.
Roadside emergencies
49

Never use wheels or lug
nuts different than the
original equipment as this could
damage the wheel or mounting
system. This damage could allow
the wheels to come off while the
vehicle is being driven.
15. Replace any wheel trim.
16. Stow the jack, handle and lug wrench.
17. Unblock the wheels.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 160 km (100 miles), and again at 800 km (500
miles) of new vehicle operation and after any wheel disturbance (tire
rotation, changing a flat tire, wheel removal, etc.).
Bolt size Wheel lug nut torque*
Nm Lb-ft
M14 x 1.5 200-225 150-165
* Torque specifications are for nut and bolt threads free of dirt and rust. Use
only Ford recommended replacement fasteners.
On all two-piece flat wheel nuts,
apply one drop of motor oil between
the flat washer and the nut. Do not
apply motor oil to the wheel nut
threads or the wheel stud threads.
When a wheel is installed, always remove any corrosion, dirt or
foreign materials present on the mounting surfaces of the wheel or
the surface of the front disc brake hub and rotor that contacts the wheel.
Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to
come off while the vehicle is in motion, resulting in loss of control.
JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.

Roadside emergencies
51

Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. 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 to its
optimum shift feel.
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 any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged battery.
