2003 Mercury Mountaineer ABS

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.
Air bag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.
Safety belt:Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Charging system:Illuminates when
the battery is not charging properly.
Check gage (if equipped):
Illuminates when any of the
following conditions has occurred:
•The engine coolant temperature
is high.
•The engine oil pressure is low.
•The fuel gauge is at or near empty.
Hi temp low oil (if equipped):
Illuminates when the engine coolant
temperature is high or the engine oil
pressure is low. Refer to engine
coolant temperature gauge or engine
oil pressure gauge in this chapter).

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; any
pulsations or mechanical noise you may feel or hear is normal.
ABS warning lamp
ABS
TheABSlamp in the instrument cluster momentarily illuminates when
the ignition is turned to 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.)
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned ON) until the
parking brake is released.
Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park).

Roadside Emergencies

•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 and/or
ethanol 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.
•FFV fuel tanks may contain zero to 85 percent ethanol. Any fuel
blends containing gasoline and ethanol should be treated the same as
“Fuel Ethanol”. To identify if your vehicle is an FFV, check your VIN
or the label on the inside of your fuel filler door. When checking the
VIN look for the engine type identifier (8th character). If your vehicle
is an FFV, then the character will be labeled as a“K.”
Pure ethanol is the alcohol which is the intoxicating agent in liquor, beer
and wine. It is distilled from the fermentation of plants such as field corn
and sugar cane. When ethanol is used in the making of motor fuels, a
small amount of a bad tasting chemical is added to discourage beverage
use. The resulting fuel is called E
d100 meaning 100% pure ethanol
diluted by 2% to 5% gasoline as the“denaturant.”
Fuel ethanol (summer blend
d) is then made by adding 15% more
unleaded gasoline. The resulting fuel also has a higher octane rating than
unleaded regular gasoline and other properties which allow engine
designs with greater efficiency and power.
Winter blends may contain up to 30% (E70)unleaded gasoline (25% plus
the denaturant) to enhance cold engine starts. Severely cold weather
may require additional measures for reliable starting. Refer toCold
Weather Startingin theDrivingchapter.
Ethanol is more chemically active than gasoline. It corrodes some metals
and causes some plastic and rubber components to swell, break down or
become brittle and crack, especially when mixed with gasoline. Special
materials and procedures have been developed for flexible fuel vehicles
and the dispensers used by ethanol fuel providers.
Maintenance and Specifications

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 and stays on after 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.
Fuel Filter
For fuel filter replacement, see your dealer or a qualified service
technician. Refer to the scheduled maintenance guide for 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.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,600 km (1,000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3,000 km–5,000 km (2,000 miles-3,000 miles).
