Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[GF21110( ALL)01/96]
With the tires inflated to the specified pressure
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[GF21120( ALL)01/96]
GCWR (Gross Combined Weight Rating)
*
[GF21130( ALL)01/96]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[GF21140( ALL)01/96]
Maximum Trailer Weight Rating
*
[GF21150( ALL)01/96]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It is specified by the
manufacturer and is determined by subtracting
the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight
of the driver from the GCWR for the towing
vehicle.
*
[GF21160( ALL)01/96]
Maximum Trailer Weight
*
[GF21170( ALL)01/96]
The maximum trailer weight is the maximum
weight of a trailer the loaded vehicle is
permitted to tow. It is determined by subtracting

Checking the engine coolant
*
[MC11800( ALL)01/96]
Your vehicle's engine coolant protects the engine
from overheating in the summer and from
freezing in the winter. Check the level of the
engine coolant at least once a month, but
preferably each time you stop for fuel. Simply
look at the engine coolant recovery reservoir
located in the engine compartment. To locate
this reservoir, see the diagram of your vehicle's
engine underEngine typesin this chapter.
*
[MC11850( ALL)01/96]
If the engine coolant has not been checked for a
long period of time the engine coolant reservoir
may eventually empty. If the engine coolant
reservoir empties, check the engine coolant level
in the radiator. Read the following warnings
before removing the radiator cap. If it is
necessary to fill the radiator, refer to theEngine
Coolant Refill Procedurein this chapter for
instructions.
[MC11900( M)01/96]
Your cooling system is of the coolant recovery
type. The engine coolant recovery reservoir is a
one-piece molded unit. Engine coolant in the
system expands with heat and overflows into the
engine coolant recovery reservoir. When the
system cools down, coolant is drawn back into
the radiator.

Removing the fuel cap
*
[MC30500( ALL)01/96]
The proper instructions for removing the fuel
cap are as follows:
*
[MC30600( ALL)01/96]
q
Unscrew the fuel cap by exerting pressure on
the plastic lock bar and rotating the fuel cap
counterclockwise.
*
[MC30700( ALL)01/96]
q
Turn the fuel cap 1/2 to 3/4 of a turn until a
hissing sound is heard. When the hissing
sound stops, continue rotating
counterclockwise to remove the fuel cap.
*
[MC30800( ALL)01/96]
q
Make sure that you follow the above fuel cap
removal instructions and use caution. Such
caution will minimize the possibility of fuel
spraying during removal of the fuel cap.
*
[MC30900( ALL)01/96]
To replace and secure the fuel cap; place it in
position and rotate it clockwise until it clicks
(ratchets). Doing so will not damage or break
the fuel cap. The ratcheting mechanism allows
the fuel cap to be sealed without overtightening.
*
[MC31000( ALL)01/96]
If you lose the fuel cap, replace it with an
authorized Motorcraft or equivalent part.

NOTE: If you replace your fuel cap with an
aftermarket fuel filler cap, the customer
warranty may be void for any damage
to the fuel tank and/or fuel system.

Fuels can cause severe eye irritation and possibly
eye damage. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with large
amounts of water for 15 minutes, and seek
medical attention.

[MC35200( ALL)01/96]
If you are taking the medication ªAntabuseº or
other forms of disulfiram for the treatment of
alcoholism, vapor or skin contact with a
gasoline-methanol blend may cause the same
kind of adverse reaction as drinking an alcoholic
beverage. In sensitive individuals, serious
personal injury or sickness could result. Consult
a physician promptly if you experience an
adverse reaction.

[MC35300( ALL)01/96]
Filling the fuel tank
*
[MC35400( ALL)01/96]
RWARNING
Do not overfill the fuel tank. The pressure
in an overfilled tank may cause leakage
and lead to fuel spray and fire.
*
[MC35500( ALL)01/96]
To fill the fuel tank properly:
*
[MC35600( ALL)01/96]
NOTE: Extinguish all lit cigarettes, other
smoking materials, and any open
flames before fueling your vehicle.
*
[MC35700( ALL)01/96]
1. Remove the fuel cap by following the
instructions above underRemoving the Fuel
Capin this chapter. Proceed to add fuel to
the tank only if your vehicle is on level
ground.

Running Out of Fuel
*
[MC36200( ALL)01/96]
If your vehicle runs out of fuel, try to stop on
level ground away from traffic. Add at least two
gallons (8 liters) of fuel to start your vehicle
again. If your vehicle is not on level ground,
you may need as much as five gallons (20 liters)
of fuel to start it.
*
[MC36300( ALL)01/96]
You may need to crank the engine several times
before the fuel system starts to pump fuel from
the tank to the engine.

[MC36400( ALL)01/96]
Fuel Economy
*
[MC36500( ALL)01/96]
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
*
[MC36600( ALL)01/96]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[MC36700( ALL)01/96]
To calculate fuel economy:
*
[MC36800( ALL)01/96]
1. Fill the tank completely and record the
initial odometer reading.
*
[MC36900( ALL)01/96]
2. Every time you buy fuel record the
amount (in gallons or liters) purchased.
*
[MC37000( ALL)01/96]
3. After at least three to five tankfuls, fill the
fuel tank and record the final odometer
reading.
