low oil pressure Mercury Mountaineer 2002 Owner's Manuals

Check gage (if equipped)
Illuminates when the engine coolant
temperature is high, the engine oil
pressure is low or the fuel gauge is
at or near empty. Refer toEngine
coolant temperature gauge, Engine oil pressure gaugeorFuel gauge
in this chapter for more information.
Oil pressure/Engine coolant
Illuminates when the engine coolant
temperature is above the normal
range or the engine oil pressure is
outside normal range. Check the
engine oil and coolant level refer to
Adding engine oilandAdding coolantin theMaintenance and care
chapter.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has
malfunctioned and is disabled, however, the normal brake system will
still function unless the brake warning light also remains illuminated and
parking brake is off. Refer toBrakesin theDrivingchapter for more
information.

Engineoil pressure gauge
Indicates engine oil pressure. At
normal operating temperature, the
needle will be in the normal range
(the area between the“L”and“H”);
if the needle goes below the normal
range, stop the vehicle as soon as
safely possible and switch off the
engine immediately. Check the oil
level. Add oil if needed (refer to
Engine oilin theMaintenance
and carechapter). If the oil level is correct, have your vehicle checked
at your dealership or by a qualified technician.
Fuel gauge
Displays approximately how much
fuel is in the fuel tank. The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
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 DOOR icon and arrow indicates which side of the vehicle the
fuel filler door is located.
ELECTRONIC COMPASS/TEMPERATURE DISPLAY (IF EQUIPPED)
OUTSIDE AIR TEMPERATURE
The outside temperature display is
contained in the instrument cluster
and displays all the time. If
equipped with the DEATC climate
control system, the outside
temperature will be displayed there.
To turn the display off or change the display from English to metric see
your dealer.
Compass
The compass reading may be affected when you drive near large
buildings, bridges, power lines and powerful broadcast antennas.
Magnetic or metallic objects placed in, on or near the vehicle may also
affect compass accuracy.

message center is as follows:
1. FUEL LEVEL
2. WASHER FLUID LEVEL
3. OIL LIFE IN XX%
4. ENGINE TEMP
5. OIL PRESSURE
6. TIRE PRESSURE SYSTEM (if equipped)
7. BRAKE FLUID LEVEL
8. CHARGING SYSTEM
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 several
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 will reappear on the display every minute from the reset.
•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.

Roadside emergencies

•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
theMaintenance and Specificationschapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
Flex fuel (E-85) cruising range
Because E-85 fuel contains less energy per gallon than gasoline, you will
experience an increase in fuel consumption. You can expect your Miles
