AUXILIARY SWITCHES
The auxiliary switchboard on the center
console makes aftermarket customization
easier, with four prewired switches
attached to the power distribution box for
electrical accessories. When using the auxiliary switches for an
extended period of time, we recommend
that the engine is running to prevent the
battery from running out of charge.
A fuse and relay kit is included with this
option. The kit contains fuses and relays
for the pre-fusebox, located under the
driver
’s seat. Refer to the instructions
included with the kit. See an authorized
dealer for service.
There is one power lead connector for each
switch. These can be found at either the
43-way connector for the AUX 1 and AUX
2 switches or the 6-way connector for the
AUX 3 and AUX 4 switches. Both
connectors are behind the passenger side
cup holder.
The relays are coded as follows: Fuse Rating

When the oil change message 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 message
appearing. Make sure you reset the
Intelligent Oil-Life Monitor after each oil
change. See Changing the Engine Oil
and Oil Filter (page 283).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) 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 correctly 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.
Make sure to change your vehicle ’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using a Ford-approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and
correct pressure.

correctly, it is important to have the

This can help identify potential issues and
prevent major problems. We recommend

performed at every scheduled
maintenance interval to help make sure
your vehicle keeps running correctly. Multi-point inspection

MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.When to expect the oil change message
