1999 Mercury Sable fuel pump

Pull the release lever
to release the brake.
Driving with the
parking brake on will
cause the brakes to
wear out quickly and
reduce fuel economy.
STEERING
Your vehicle is equipped with power steering. Power
steering uses energy from the engine to help steer
the vehicle.
To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme
right or the extreme left for more than a few
seconds when the engine is running.
²Do not operate the vehicle with a low power
steering pump fluid level.
If the power steering system breaks down (or if the
engine is turned off), you can steer the vehicle
manually, but it takes more effort.
If the steering wanders or pulls, the condition could
be caused by any of the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage

HAZARD FLASHER
Use only in an emergency to warn traffic of vehicle
breakdown, approaching danger, etc. The hazard
flashers can be operated when the ignition is off.
²The hazard lights
control is located on
top of the steering
column.
²Depress hazard
lights control to
activate all hazard
flashers
simultaneously.
²Depress control again to turn the flashers off.
RESETTING THE FUEL SHUT-OFF SWITCH
After a collision, if the engine cranks but does not
start, the fuel pump shut-off switch may have been
activated. The shut-off switch is a device intended to
stop the electric fuel pump when your vehicle has
been involved in a substantial jolt. Use the following
procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the Resetting the
fuel shut-off switch by pushing in the reset button.
4. Turn the ignition to the ON position. Pause for a
few seconds and return the key to the OFF position.
5. Make a further check for leaks in the fuel system.

Roadside emergencies

Running out of fuel
Avoid running out fuel because this situation may
have an adverse affect on modern powertrain
components.
If you have run out of fuel:
²You may need to crank the engine several times
before the system starts to pump fuel from the
tank to the engine.
²Your ªService Engine Soonº light may come on.
For more information on the ªService Engine
Soonº light, refer to theInstrumentationchapter.
Fuel Filter
Your vehicle is equipped with a fuel filter that is
mounted on the underbody.
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.
If you replace the fuel filter, replace it 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 fillups 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).

The advertised fuel capacity of the fuel tank on your
vehicle is equal to the rated refill capacity of the fuel
tank as listed in the Refill Capacities chart in this
ªOwner Guide.º The advertised capacity is the
amount of the Indicated Capacity and the Empty
Reserve combined. Indicated Capacity is the
difference in the amount of fuel in a full tank and a
tank when the fuel gauge indicates empty. Empty
Reserve is the small amount of usable fuel remaining
in the fuel tank after the fuel gauge indicates empty.
The amount of Empty Reserve varies and
should not be relied upon to increase driving
range. When refueling your vehicle after the
fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised
capacity of the fuel tank due to the empty
reserve still present in the tank.
Filling the tank
For consistent results:
²Use the same filling rate setting (low Ð medium
Ð high) each time the tank is filled.
²Allow three automatic click-offs when filling.
²Always use the recommended octane rating of a
known quality gasoline, preferably a national
brand.
²Use the same side of the same pump and have
the vehicle facing the same direction each time
you fill up.
²Have the vehicle loading and distribution the
same every time.
Your results will be most accurate if your filling
method is consistent.
Calculating fuel economy
1. Fill the fuel tank completely and record the initial
odometer reading.
