When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of 1
psi (7 kPa) in inflation pressure.
Check your tire pressures
frequently and adjust them to the
proper pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the pressure in your
tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note: If you are checking tire
pressure when the tire is hot, (for
example, driven more than 1 mile
[1.6 kilometers]), never bleed or
reduce air pressure. The tires are
hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.
Note: If you have to drive a
distance to get air for your tire(s),
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the air pressure inside to go
up as you drive.
2. Remove the cap from the valve
on one tire, then firmly press
the tire gauge onto the valve
and measure the pressure. 3.
Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release
air by pressing on the metal stem
in the center of the valve. Then
recheck the pressure with your tire
gauge.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
Note: Some spare tires operate at
a higher inflation pressure than the
other tires. For T type mini-spare
tires, see the Dissimilar spare wheel
and tire assembly information for
a description. Store and maintain
at 60 psi (4.15 bar). For full-size
and dissimilar spare tires, see the
Dissimilar spare wheel and tire
assembly information for a
description. Store and maintain at
the higher of the front and rear
inflation pressure as shown on the
Safety Compliance Certification
Label or Tire Label.
6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.
7. Check the sidewalls to make sure there are no gouges, cuts
or bulges.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when
you sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
We have established regular maintenance
intervals for your vehicle based upon
rigorous testing. It is important that you
have your vehicle serviced at the proper
times. These intervals serve two purposes;
one is to maintain the reliability of your
vehicle and the second is to keep your cost
of owning your vehicle down.
It is your responsibility to have all
scheduled maintenance performed and to
make sure that the materials used meet
the specifications identified in this owner's
manual. See Capacities and
Specifications (page 152).
Failure to perform scheduled maintenance
invalidates warranty coverage on parts
affected by the lack of maintenance.
Why Maintain Your Vehicle at Your
Dealership?
Factory-trained Technicians
Service technicians participate in extensive
factory-sponsored certification training to
help them become experts on the
operation of your vehicle. Ask your
dealership about the training and
certification their technicians have
received. Genuine Ford and Motorcraft
Replacement Parts
Dealerships stock Ford, Motorcraft and
Ford-authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed
at your dealership carry a nationwide
24-month or unlimited mile (kilometer)
parts and labor limited warranty.
If you do not use Ford authorized parts they
may not meet our specifications and
depending on the part, it could affect
emissions compliance.
Convenience
Many dealerships have extended evening
and Saturday hours to make your service
visit more convenient and they offer one
stop shopping. They can perform any
services that are required on your vehicle,
from general maintenance to collision
repairs.
Note:
Not all dealers have extended hours
or body shops. Please contact your dealer
for details.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved
reliability, durability and resale value. To
maintain the proper performance of your
vehicle and its emission control systems,
make sure you have scheduled
maintenance performed at the designated
intervals.
Your vehicle is very sophisticated and built
with multiple, complex, performance
systems. Every manufacturer develops
these systems using different
specifications and performance features.
That is why it is important to rely upon your
dealership to properly diagnose and repair
your vehicle.

COMPATIBILITY
WARNING: Do not place objects
or mount equipment on or near the
airbag cover, on the side of the front or
rear seatbacks, or in areas that may
come into contact with a deploying
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING: Do not fasten antenna
cables to vehicle wiring, fuel pipes and
brake pipes. WARNING:
Keep antenna and
power cables at least 4 in (10 cm) from
any electronic modules and airbags. Note:
We test and certify your vehicle to
meet electromagnetic compatibility
legislation. It is your responsibility to make
sure that any equipment an authorized
dealer installs on your vehicle complies with
applicable local legislation and other
requirements. Installation of some
aftermarket electronic devices could
degrade the performance of vehicle
functions, which use radio frequency signals
such as broadcast radio receiver, tire
pressure monitoring system, push button
start, Bluetooth®
connectivity or satellite
navigation.
Note: Any radio frequency transmitter
equipment in your vehicle (such as cellular
telephones and amateur radio transmitters)
must keep to the parameters in the
following illustrations and table. We do not
provide any other special provisions or
conditions for installations or use.
