damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and have your vehicle serviced
immediately.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Check fuel cap:Illuminates 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 the
Maintenance and Specificationschapter.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position when the engine is not running, or
in a position between ON and START, or by applying the parking brake
when the ignition is turned to the ON position. If the brake system
warning light does not illuminate at this time, seek service immediately
from your dealership. Illumination after releasing the parking brake
indicates low brake fluid level and the brake system should be inspected
immediately by your servicing dealership.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately. Normal
braking is still functional unless the brake warning light also is
illuminated.

BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Refer toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking; this is
normal and should be no reason for concern.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled,
normal braking is still effective. (If
your BRAKE warning lamp
illuminates with the parking brake
released, have your brake system serviced immediately.)

Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, avoid locking of the wheels. Use
a“squeeze”technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. If your vehicle
is equipped with a Four Wheel Anti-Lock Brake System (ABS), apply the
brake steadily. Do not“pump”the brakes. Refer to theBrakessection of
this chapter for additional information on the operation of the anti-lock
brake system.
Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company because it can affect
the safety and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover and/or serious
personal injury or death.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design and load-carrying capacity. If you have questions regarding
tire replacement, see an authorized Ford or Lincoln/Mercury dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford Motor Company recommends, you should not use
these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure as well as the increased
risk of loss of vehicle control.
Do not use“aftermarket lift kits”or other suspension modifications,
whether or not they are used with larger tires and wheels.
These“aftermarket lift kits”could adversely affect the vehicle’s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.

•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking“Antabuse”or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
When refueling always shut the engine off and never allow
sparks or open flames near the filler neck. Never smoke while
refueling. Fuel vapor is extremely hazardous under certain conditions.
Care should be taken to avoid inhaling excess fumes.
The flow of fuel through a fuel pump nozzle can produce static
electricity, which can cause a fire if fuel is pumped into an
ungrounded fuel container.
Use the following guidelines to avoid static build-up when filling an
ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
•Keep the fuel pump nozzle in contact with the fuel container while
filling.
•DO NOT use a device that would hold the fuel pump handle in the fill
position.

Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/8 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8 of a turn until it
stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it stops.
If the“Check Fuel Cap”
indicator comes on or if“Service Engine
Soon/Check Engine”indicator comes on and stays on when you start the
engine, the fuel filler cap may not be properly installed. Turn off the
engine, remove the fuel filler cap, align the cap properly and reinstall it.
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 pressure or
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. The use of leaded fuel is prohibited by law
and could damage your vehicle.
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
