TachometerThe tachometerThe tachometer displays the approximate engine
revolutions per minute (rpm), or how fast the
engine is running.
You can drive your vehicle at most rpm points on
the tachometer but you must stay out of the red
zone.
Engine Coolant Temperature GaugeThis gauge indicates the temperature of the engine
coolant, not the coolant level. If the coolant is not
at its proper level or mixture, the gauge indication
will not be accurate.

18The pointer moves from the C (cold) mark into the
NORMAL band as the engine coolant warms up. It
is acceptable for the pointer to fluctuate within the
NORMAL band under normal driving conditions.
Under certain driving conditions such as, heavy stop
and go traffic, or driving up hills in hot weather,
the pointer may indicate at the top of the NORMAL
band.
If, under any circumstances, the pointer moves
above the NORMAL band, the engine is overheating
and continued operation may cause engine damage.
If your engine overheats:
1. Pull off the road as soon as it is safely possible.
2. Turn off the engine.3. Let the engine cool.DO NOT REMOVE
COOLANT SYSTEM FILL CAP UNTIL THE
ENGINE IS COOL.
4. Check the coolant level following the
instructions on checking and adding coolant to
your engine, seeEngine Coolantin the Index.
If you do not follow these instructions, you or
others could be injured.
If the coolant continues to overheat, have the
coolant system serviced as soon as possible.

displayed when your engine oil level is low. If this
warning message is displayed, check the level of the
engine oil.
To check your oil:
1. Park your vehicle on level ground, turn off the
engine and wait at least 5 minutes for the oil
to drain back into the oil pan.
2. Use the dipstick to check the oil. If the level is
low, add oil, but do not overfill.
If you are parked on a steep incline, the LOW OIL
LEVEL warning may come on when you start your
vehicle, even though the oil is at the correct level.
The oil level is monitored while the engine is off,
so that the oil can drain into the oil pan to be
measured. Some after-market devices such as
remote starters, if improperly installed, can cause

monitoring system. This may also cause the LOW
OIL LEVEL warning to come on when you start
your vehicle, even though the oil is at the correct
level.
For further information about adding oil, seeEngine
oilin the index.
CHECK CHARGING SYSTEMÐ This warning
message is displayed when the electrical system is
not maintaining a proper voltage. If you are running
electrical accessories when the engine is idling at a
low speed, turn off as many of the electrical loads
as soon as safely possible. If this warning stays on
or comes on when the engine is operating at
normal speeds, have the electrical system checked
as soon as safely possible.
LOW FUEL LEVELÐ This warning message is
displayed when you have approximately 50 miles
(80 km) or less left before you run out of fuel.LOW ENGINE COOLANTÐ This warning
message is displayed when the engine coolant level
is low. Stop the vehicle as soon as safely possible,
turn off the engine and let it cool. Check the
coolant and level, and add coolant as required
following the instructions in theMaintenance and
Carechapter. If you do not follow these
instructions, you or others could be injured.

72When in AUTOMATIC and weather conditions
require heat, air will be sent to the floor. But, a
feature is included in your EATC to prevent
blowing cold air to the floor if the engine coolant is
not warm enough to allow heating. In 3-1/2
minutes or less, the fan speed will start to increase
and the airflow will change to the floor area.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you to
select special air discharge locations. A thumbwheel
allows you to adjust the fan speed to suit your
needs.
Temperature selectionThe RED and BLUE buttons at the upper left of the
Control are for temperature selection. The RED
Button will increase the set temperature and the
BLUE Button will lower the set temperature.
Pressing a button and releasing it will change the
set temperature one degree. Holding either button
in will rapidly change the temperature setting in
one degree increments to either65ÊF(18ÊC)
(BLUE) or85ÊF(29ÊC)(RED). Then, the set
temperature will jump 5 Ê and stop at either60ÊF
(16ÊC)which is maximum cooling or90ÊF(32ÊC)
which is maximum heating. When you select60ÊF
(16ÊC) or90ÊF(32ÊC), the fanwill go to HI speed
for maximum air flow.
The average temperature range used is between
68ÊF(20ÊC) and78ÊF(26ÊC).Changing the
temperature setting by several degrees outside this
range or overriding to60ÊF(16ÊC) or90ÊF(32ÊC)
will not speed up the heating or cooling process.

NOTE:Engine torque reduction isNOTactive
when engine coolant temperature is below-10ÊF
(-23ÊC).
During the Traction Control
TM
function, which most
often occurs during low speed acceleration on
slippery surfaces, a noise may be heard coming from
the engine compartment. This is normal and may
last for a few seconds during the acceleration of the
vehicle.
In general, this system improves your vehicle's
stability and acceleration performance when road
conditions warrant. Traction Control
TM
is fully
effective at all vehicle speeds.
If the Traction Control
TM
system is cycled
excessively, the brake portion of the system will
shut down to prevent the rear brakes from
overheating. A limited Traction Control
TM
function
using engine torque will still control wheels from
spinning. A cooling down period is required to
prevent damage to the brakes. This time periodvaries and depends on brake usage during the
cooling down period. Anti-Lock braking is not
affected and will function normally during the cool
down period.
After the cool down period, the full Traction
Control
TM
function is restored.
Air Suspension SystemYour vehicle is equipped with an automatic load
leveling air suspension system. This system
maintains the vehicle height at a constant level by
automatically adding air or releasing air from the air
springs to offset changes in vehicle loads.
A shutoff switch is located in the trunk behind the
left hand vertical trim panel. If this switch is in the
OFF position, the automatic leveling system will not
operate. The switch should be OFF whenever
jacking up the vehicle. ªAIR RIDE SWITCH OFFº

EngineCoolant
WARNING
Th ecoolin gfan is automati can dmay

230Use Ford Premium Cooling System Fluid
E2FZ-19549-AA (in Canada, Motorcraft CXC-8-B) or
an equivalent premium engine coolant that meets
Ford specification ESE-M97B44-A. Ford Premium
Engine Coolant is an optimized formula that will
protect all metals and rubber elastomers used in
Ford cooling systems for 4 years or 50,000 miles
(80,000 km).
Do not use alcohol or methanol antifreeze or any
engine coolants mixed with alcohol or methanol
antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm
your engine cooling system. The use of an improper
coolant may void the warranty of your vehicle's
engine cooling system.Recycled engine coolantFord Motor Company recommends that Ford and
Lincoln-Mercury dealers use recycled engine coolant
produced by Ford-approved processes. Not all
coolant recycling processes produce coolant whichmeets Ford specification ESE-M97B44-A, and use of
such coolant may harm engine and cooling system
components.
Always dispose of used automotive fluids in a
responsible manner. Follow your community's
regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacityTo find out how much fluid your vehicle's cooling
system can hold, refer toRefill capacitiesin the
Capacities and specificationschapter.
Have your dealer check the engine cooling system
for leaks if you have to add more than a quart
(liter) of engine coolant per month.Severe winter climateIf you drive in extremely cold climates (less than
-34ÊF[-36ÊC]), it may benecessary to increase the
coolant concentration above 50%. Refer to the chart
on the coolant container to ensure the coolant

concentration in your vehicle is such that the
coolant will not freeze at the temperature level in
which you drive during winter months. Never
increase the engine coolant concentration above
60%. Leave a 50/50 mixture of engine coolant and
water in your vehicle year-round in non-extreme
climates.
Proper procedures for a complete coolant drain and
flush of the cooling system can be found in theCar
Service Manual.Following these recommended
procedures will ensure that the specified coolant
level and a 50/50 or appropriate mixture of coolant
and water is maintained.Engine Coolant Refill ProcedureWhen the entire cooling system is drained and
refilled, the following procedure should be used to
ensure a complete fill:
NOTE:It is imperative the following procedure be
adhered to. Failure to do so could result in damage
to your engine.
q
Remove coolant reservoir pressure cap.
q
Remove the engine coolant outlet tube fill plug
on the engine.
q
With the engine off and cool, add a 50/50
mixture of recommended cooling system fluid
and water to the coolant outlet tube fill neck
until the reservoir is full.
NOTE:DO NOT FILL COOLANT SYSTEM
THROUGH COOLANT RESERVOIR. COOLANT
WILL NOT ENTER ENGINE, WHICH CAN LEAD
TO ENGINE DAMAGE.
NOTE:Avoid spilling coolant on the front end
accessory drive belt, as this will allow the belt to
slip and become noisy.
q
Reinstall the pressure cap to the coolant
reservoir.
q
Continue filling at the engine coolant tube fill
neck slowly while allowing air to escape.
