Low tire pressure warning:
Illuminates when your tire pressure is
low. If the light remains ON at start
up or while driving, the tire pressure
should be checked. Refer toInflating
Your Tiresin theTires, Wheels and Loadingchapter. When the ignition
is first turned to ON, the light will illuminate for 3 seconds to ensure the
bulb is working. If the light does not turn ON or begins to flash, have the
system inspected by your authorized dealer. For more information on this
system, refer toUnderstanding Your Tire Pressure Monitoring System
in theTires, Wheels and Loadingchapter.
Low fuel (RTT) (if equipped):
Displays when the fuel level in the
fuel tank is at or near empty (refer
toFuel gaugein this chapter).
Check fuel cap (RTT)
(if equipped):Displays when the
fuel cap may not be properly
installed. Continued driving with
this light on may cause the Service
engine soon warning light to come
on. Refer toFuel filler capin theMaintenance and Specifications
chapter.

Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
The ignition should be in the OFF position while the vehicle is being
refueled. When the gauge first indicates empty, there is a small amount
of reserve fuel in the tank. When refueling the vehicle from empty
indication, the amount of fuel that can be added will be less than the
advertised capacity due to the reserve fuel.
The FUEL icon and arrow indicates which side of the vehicle the fuel
filler door is located.
Refer toFilling the tankin theMaintenance and Specifications
chapter for more information.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
by your authorized dealer as soon as possible.
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between “L” and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine oil level. Add oil if needed. If the oil
level is correct, have your vehicle checked by your authorized dealer.

System warnings
System warnings alert you to possible problems or malfunctions in your
vehicle’s operating systems.
In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for 4
seconds.
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
RESET control and clearing the warning message.
Warning messages that have been reset are divided into three categories:
•They cannot be cleared until the condition is corrected.
•They will reappear on the display ten minutes from the reset.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.

TIRE PRESSURE MONITORING SYSTEM (TPMS)
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.
Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale.
The Tire Pressure Monitoring System complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
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 tiresin this chapter. Failure to properly maintain your
tire pressure could increase the risk of tire failure, loss of control,
vehicle rollover and personal injury.

any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•Do not install chains on the front wheels. Chains on the front wheels
may interfere with suspension components.
•Chains are not recommended for use on the P275/55R20 tire.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•If possible, avoid fully loading your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
•The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
•Do not exceed 30 mph (48 km/h) with tire chains on your vehicle.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading

FUEL FILTER
For fuel filter replacement, see your authorized dealer. Refer to
scheduled maintenance informationfor the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Motorcraft part. The
customer warranty may be void for any damage to the fuel system
if an authorized Motorcraft fuel filter is not used.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive vacuum in
the fuel tank may damage the fuel system or cause the fuel cap
to disengage in a collision, which may result in possible personal injury.
Automotive fuels can cause serious injury or death if misused or
mishandled.
Gasoline may contain benzene, which is a cancer-causing agent.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials
and any open flames before
refueling your vehicle.
•Always turn off the vehicle before
refueling.

If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The customer warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
If you do not use the proper fuel filler cap, excessive vacuum in
the fuel tank may damage the fuel system or cause the fuel cap
to disengage in a collision, which may result in possible personal injury.
Choosing the right fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Your vehicle was not designed to run on E85 fuels that
are blended with a maximum of 85% ethanol. The use of leaded fuel is
prohibited by law and could damage your vehicle. Do not use fuel
containing methanol. It can damage critical fuel system components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives. Studies indicate that
these additives can cause your vehicle’s emission control system to
deteriorate more rapidly. In Canada, premium grade fuel generally
contains more metallic additives than regular grade fuel. We recommend
using regular grade fuel. In Canada, many fuels contain metallic
additives, but fuels free of such additives may be available; check with
your local fuel dealer.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
“Regular” unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as “Regular” that
are sold with octane ratings of 86 or lower in high altitude areas.
