vehicle with the tires installed, or checking
tire inflation. Do not place tires near heaters
or heating devices used to warm the room
where the tires are stored. Do not apply heat
or blow heated air directly on the tires.
Always inspect the tires after storage periods
and before use.
USING SNOW CHAINS
WARNINGS
If you choose to install snow tires on
your vehicle, they must be the same
size, construction, and load range as the
original tires listed on the tire placard, and
they must be installed on all four wheels.
Mixing tires of different size or construction
on your vehicle can adversely affect your
vehicle's handling and braking, and may lead
to loss of vehicle control. Do not use snow chains or cables on
this vehicle as they may cause damage
to your vehicle which may lead to loss of
vehicle control. Snow chains have not been approved for
use on your vehicle.
The original equipment tires on your vehicle
may have an all-weather tread design to
provide traction, handling, and braking
performance in year-round driving. You may
install snow tires for improved traction when
driving in areas with sustained periods of
snow or icy driving conditions.
TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system is
NOT a substitute for manually checking
tire pressure. The tire pressure should be
checked periodically (at least monthly) using
a tire gauge, see Inflating your tires in this
chapter. Failure to properly maintain your
tire pressure could increase the risk of tire
failure, loss of control, vehicle rollover and
personal injury. Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle
has tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure
monitoring system (TPMS) that illuminates a
low tire pressure telltale when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle ’s handling and stopping ability.

Your vehicle is equipped with an information
display, which indicates the proper oil
change interval. This interval may be up to
one year or 10000 miles (16000 kilometers).
When ENGINE OIL CHANGE DUE or OIL
CHANGE REQUIRED appears in the
information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 miles (800
kilometers) of the
ENGINE OIL CHANGE
DUE or OIL CHANGE REQUIRED message
appearing. Make sure you reset the oil
monitoring system after each oil change.
See
Engine Oil Check (page 290).
If your information display resets
prematurely, becomes inoperative or the
vehicle battery becomes discharged or
disconnected, the oil monitoring system
resets to 100% oil life. You should change
your engine oil one year or 10000 miles
(16000 kilometers) from the previous oil
change. Never exceed one year or 10000
miles (16000 kilometers) between oil change
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.
Ford Motor Company has recommended
maintenance intervals for various parts and
component systems based upon engineering
testing. Ford Motor Company relies upon this
testing to determine the most appropriate
mileage for replacement of oils and fluids to
protect your vehicle at the lowest overall cost
to you and recommends against
maintenance schedules that deviate from
the scheduled maintenance information.
We strongly recommend the use of only
genuine Ford, Motorcraft or Ford-authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and the Ford Workshop
Manual list the recommended additives and
chemicals for your vehicle. We do not
recommend using chemicals or additives not
approved by us as part of your vehicle
’s
normal maintenance. Please consult your
warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal
operating characteristic and, by itself, does
not necessarily indicate a concern or that the
fluid needs to be changed. However, a
qualified expert, such as the factory-trained
technicians at your dealership, should
inspect discolored fluids that also show signs
of overheating or foreign material
contamination immediately.
