AUXILIARY SWITCHES (IF
EQUIPPED)
For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
• When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
equipped with radio transmitters, for
example, two-way radios, telephones
and theft alarms. Any such equipment
installed in your vehicle should comply
with Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulations, and
should be installed by an authorized
dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford electrical or electronic
accessories or components to your
vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of other electrical
systems in the vehicle. The auxiliary switch option package
provides six switches mounted in the
overhead console. These switches operate
when the vehicle is running or from battery
power, depending on the switchable fuse
AUXF4's location in the upfitter relay box.
We recommend, however, that the engine
remain running to maintain battery charge
when using the auxiliary switches for
extended periods of time or higher current
draws.
Note:
When your vehicle has a diesel
engine, use the auxiliary switches only when
the engine is running. The glow plugs also
drain battery power when the ignition key is
in the on position. Using the auxiliary
switches, even for limited amounts of time,
can cause your battery to drain quickly and
prevent your vehicle from restarting.
When switched on, the auxiliary switches
provide electrical battery power for a
variety of personal or commercial uses.
Switches 1 through 4 provide 25 amps.
Switches 5 and 6 provide 40 amps.
The relay box for the auxiliary switches is
in the rear of the engine compartment,
near the back wall. See your authorized
dealer for service.
The relays are coded as shown:

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 mi
(800 km) of the message appearing. Make
sure you reset the Intelligent Oil-Life
Monitor after each oil change. See
Oil
Change Indicator Reset (page 356).
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.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption this includes extended time
at high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. As a result, you
need to check the engine oil level at every
refueling and adjust to maintain proper
levels to avoid engine damage.
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.
We have recommended maintenance
intervals for various parts and component
systems based upon engineering testing.
We rely 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
our genuine or our authorized
re-manufactured replacement parts
engineered for your vehicle.
Additives and Chemicals
This owner's manual and our 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 our 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.

Multi-Point Inspection
In order to keep your vehicle running right,
it is important to have the systems on your
vehicle checked regularly. This can help
identify potential issues and prevent major
problems. We recommend having the
following multi-point inspection performed
at every scheduled maintenance interval
to help make sure your vehicle keeps
running great.Multi-Point Inspection

vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle. NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor
Your vehicle has an Intelligent Oil-Life
Monitor that determines when you should
change the engine oil based on how you
use your vehicle. 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.
