[GF21090( ALL)01/96]
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
the weight of the loaded towing
vehicle (including passengers and cargo) from
the GCWR for the towing vehicle.

Tires
*
[MC24950( ALL)01/96]
Look at your tires each time you fill your fuel
tank. If one tire looks lower than the others,
check the pressure in all of them. Always follow
these precautions:
*
[MC25000( ALL)01/96]
q
Keep your tires inflated to the pressures that
are recommended.(SeeChecking the pressure
of the tireslater in this chapter.)
[MC25100( M)01/96]
q
Stay within the load limits that are
recommended.
*
[MC25150( ALL)01/96]
q
Make sure the weight of your load is evenly
distributed.
*
[MC25200( ALL)01/96]
q
Drive at safe speeds.
*
[MC25250( ALL)01/96]
If you do not take these precautions, your tires
may fail or go flat.
*
[MC25300( ALL)01/96]
Ford Motor Company recommends obeying
posted speed limits.
*
[MC25350( ALL)01/96]
RWARNING
Driving too fast for conditions creates the
possibility of loss of vehicle control.
Driving at very high speeds for extended
periods of time may result in damage to
vehicle components.
%*
[MC25400( ALL)01/96]
Checking the pressure of the tires
*
[MC25450( ALL)01/96]
At least once a month, check the pressure in all
your vehicle's tires, including the spare. Use an
accurate tire pressure gauge. Check the tire
pressure when tires are cold, that is, after the
vehicle has been parked for at least one hour or
has been driven less than 3 miles (5 km). You
can find the proper cold pressure on the Safety
Compliance Certification Label.

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.

*
[MC31200( ALL)01/96]
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.
*
[MC31300( ALL)01/96]
RWARNING
The fuel system may be under pressure. If
the fuel cap is venting vapor or if you
hear a hissing sound, wait until it stops
before completely removing the cap.
[MC31900( M)01/96]
You can prevent excessive condensation in the
fuel tank by keeping it over half full.

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.
*
[MC35800( ALL)01/96]
2. Make sure that you pump unleaded fuel and
put the nozzle all the way inside the fuel
filler pipe.
