The control for your air conditioning and heater
system is located at the center of the instrument
panel below the radio and will operate only
when the ignition key is turned to the ON
position. Your air conditioner and heater will
heat and/or cool your vehicle interior depending
on the function position and temperature you
select. The function selector control knob allows
you to select heating or cooling and determine

where the air will be directed. The temperature
control knob setting determines the temperature
of the air that flows into the vehicle.
*
[CF01600(F )03/96]
To turn your air conditioner and heater system
on, select any position except OFF. This will turn
the fan on and allow airflow into the vehicle. To
turn your air conditioner and heater off, select
OFF. This will turn the fan off and stop airflow
from coming into the vehicle.
*
[CF01700(F )03/96]
Temperature selection
[CF01750(F )04/96]
The Temperature knob is the rotating knob
located at the center of the control with tapered
RED and BLUE bands surrounding most of the
knob. The wide RED part of the band (full right)
is the heat or warmer area. The wide BLUE area
(full left) is the cool or unheated temperature
area. Any position selected between full right
and full left will give a temperature between the
two extreme temperatures. The cool temperature
you select will not be cooler than the outside
temperature, unless an A/C mode is selected (if
equipped).
*
[CF01900(F )03/96]
HFan speed adjustment
[CF02000(F )04/96]
The
Hknob on the control is the fan speed
knob which controls the volume of air flow.
Rotate the
Hknob to the right to increase the
amount of air entering the vehicle. Four fan
speed positions are available and are indicated
by LO, two separate dots and HI beside the
H
control knob. The HI position provides the most
air flow.

142normal idle speed. It should, however, slow
down after a short time. If it does not, have the
idle speed checked.
*
[TO05600(FM)01/96]
If the engine idle speed does not slow down
automatically, do not allow your vehicle to idle
for more than 10 minutes. Have the vehicle
checked.
*
[TO05700(FM)01/96]
RWARNING
Extended idling at high engine speeds can
produce very high temperatures in the
engine and exhaust system, creating the
risk of fire or other damage.
*
[TO05800(FM)01/96]
RWARNING
Do not park, idle, or drive your vehicle in
dry grass or other dry ground cover. The
emission system heats up the engine
compartment and exhaust system, which
can start a fire.
*
[TO05900(F )01/96]
If you consistently start your vehicle in subzero
temperatures, use an engine block heater (if
your vehicle has this option).
%*
[TO06000(F )01/96]
Engine Block Heater (If equipped)
*
[TO06100(F )01/96]
Engine block heaters are strongly recommended
if you live in a region where temperatures reach
-10ÊF (-23ÊC) orbelow. An engine block heater
warms the engine coolant, which improves
starting, warms up the engine faster, and allows
the heater-defrost system to respond quickly.
*
[TO06200(F )01/96]
RWARNING
To prevent electrical shock, do not use
your heater with ungrounded electrical
systems or two-pronged (cheater) adapters.

[TO06300(F )01/96]
For best results, plug the heater in at least three
hours before you start your vehicle. Using the
heater for longer than three hours will not
damage the engine, so you can plug it in at
night to start your vehicle the following
morning.
*
[TO06400(F )01/96]
NOTE: Be sure to disconnect the engine block
heater before driving your vehicle.

[TO06500(FM)12/95]
Guarding Against Exhaust Fumes
*
[TO06600(FM)01/96]
Carbon monoxide, although colorless and
odorless, is present in exhaust fumes. Take
precautions to avoid its dangerous effects.
*
[TO06700(FM)02/96]
RWARNING
Do not start your vehicle in a closed
garage or in other enclosed areas. Exhaust
fumes can be toxic. Always open the
garage door before you start the engine.
*
[TO06800(FM)01/96]
RWARNING
If you smell exhaust fumes inside your
vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you
smell exhaust fumes.

To avoid damaging your vehicle or your battery,
and to avoid injury to yourself, follow these
directions for preparing your vehicle to
jump-start and connecting the jumper cables in
the order they are given. If in doubt, call for
road service.
%*
[ER19800(FM)02/96]
Preparing Your Vehicle
*
[ER19850(FM)02/96]
1. Your vehicle has a 12-volt starting system, so
you need to use a 12-volt jumper system.
You will damage your starting motor,
ignition system, and other electrical parts if
you connect them to a 24-volt power supply
(either two 12-volt batteries in series or a
24-volt generator set).
*
[ER19900(FM)02/96]
2. Do not disconnect the battery of the disabled
vehicle. You could damage the vehicle's
electrical system.
*
[ER19950(FM)02/96]
3. Park the booster vehicle close to the hood of
the disabled vehicle.Make sure the vehicles
do not touch each other.Set the parking
brake on both vehicles and stay clear of the
engine cooling fan and other moving parts.
*
[ER21000(FM)02/96]
4. Check all battery terminals and remove any
excessive corrosion before you attach the
jumper cables.
*
[ER21100(FM)02/96]
5. Turn on the heater fan in both vehicles.
Turning on the fan helps protect the
electrical system from voltage surges. Turn
off all other switches and lights in both
vehicles to prevent possible damage to either
vehicle's electrical systems.

Checking hoses
*
[MC13450(FM)01/96]
Inspect all engine and heater system hoses for
deterioration, leaks and loose clamps before
adding or replacing engine coolant. Make
whatever repairs or replacements that are
necessary using Motorcraft parts or their
equivalents.

[MC13550(FM)05/96]
To drain your vehicle's engine coolant:
*
[MC13600(FM)01/96]
1. Turn off the engine and let it cool. Fully
depressurize the engine cooling system by
covering the radiator cap with a thick cloth
and turning it slowly counterclockwise to the
first stop. Step back while the pressure
releases.
*
[MC13650(FM)01/96]
