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.
The use of tire sealants is not recommended and may
compromise the integrity of your tires.
Spare tire information
The spare tire for your vehicle is stowed under the rear of your vehicle
(except cutaway and stripped chassis models).

Make sure the spare tire and jacking equipment are stowed and
secured in the proper storage location.
Never run the engine with one wheel off the ground.
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
the engine off.
5. Block the wheel that is diagonally
opposite the tire you are changing.
On E-450 vehicles, 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. Use the tapered end of the lug
nut wrench to unscrew wheel
ornaments attached by retaining
screws. Remove any wheel trim.
Insert the tapered end of the lug
nut wrench behind wheel covers or
hubcaps and twist off.
8. 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
1. Assemble the jack handle sections together and lock into the jack. Use
the jack handle to slide the jack under the vehicle.
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.
2. Position the jack to raise the front or rear wheel.
