•Diesel engine: passenger side of the engine compartment behind the
power distribution box.
Have a certified technician or your dealer service this module, if
required.
The relays are coded as follows:
Relay location Description

4 Trailer tow right turn
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.
Spare tire information
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.

3.80:Indicates the aspect ratio which gives the tires ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
4.D:Indicates a“diagonal”type tire.
R:Indicates a“radial”type tire.
5.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the tire label
You will find a tire label containing tire inflation pressure by tire size and
other important information located on the B-Pillar or the driver’s door.
TIRE CARE
Improper or inadequate vehicle maintenance can also cause tires to wear
abnormally. Here are some of the important maintenance items
Tire inflation pressure
Use a tire gauge to check the tire inflation pressure at least monthly
(check the tire inflation pressure in the spare tire every 6 months) and
before long trips. You are strongly urged to buy a reliable tire pressure
gauge, as automatic service station gauges may be inaccurate. Ford
recommends the use of a digital or dial type tire pressure gauge rather
than a stick type of tire pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
Under-inflation is the most common cause of tire failures and
may result in severe tire cracking, tread separation orblowout,
with unexpected loss of vehicle control and increased risk of injury.
Under-inflation increases sidewall flexing and rolling resistance,
resulting in heat buildup and internal damage to the tire. It also may
result in unnecessary tire stress, irregular wear, loss of vehicle control
and accidents. A tire can lose up to half of its air pressure and not
appear to be flat!
When weather temperature changes occur, tire inflation pressures also
change. A 10 degree temperature change causes a corresponding drop of
7 kPa (1 psi) in inflation pressure. Check your tire pressures frequently
and adjust them to the proper pressure which can be found on the tire
label or certification label.
