CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
The use of tire sealants may damage your tires.

The spare tire for your vehicle is stowed under the rear of your vehicle
(except cutaway and stripped chassis models or if equipped on E-350
Chassis Cab vehicles).

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 (if equipped on E-350 chassis cab
vehicles) from the storage location.
