Engine coolant temperature gauge
Indicates the temperature of the engine coolant. At normal operating
temperature, the needle remains within the normal area (the area
between the ªHº and ªCº). If it enters the red section, the engine is
overheating. Stop the vehicle as soon as safely possible, switch off the
ignition and let it cool. Refer toEngine coolantin theMaintenance
and specificationschapter.
Never remove the coolant reservoir cap while the engine is
running or hot. Steam and scalding liquid from a hot cooling
system can burn you badly.
²Standard instrument cluster
²Optional instrument cluster
This gauge indicates the temperature of the engine coolant, not the
coolant level. If the coolant is not at its proper level the gauge indication
will not be accurate. If the gauge enters the red section, the engine

²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than the MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.
²Do not put objects under the front seat which may interfere with the
airflow to the rear seats (if equipped).
²Remove any snow, ice or leaves from the air intake area (at the
bottom of the windshield and underneath the hood).
²Do not place objects over the defroster outlets. These objects can
block airflow and reduce visibility through your windshield. Avoid
placing small objects on top of the instrument panel. These objects
may fall down into the defroster outlets and block airflow, in addition
to, damaging the climate control system.
To aid in side window defogging/demisting in cold weather conditions:
1. Select the position that distributes air through the Panel and Floor.
2. Set the temperature control to full heat.
3. Set the fan speed to full fan.
4. Direct the outer panel vents towards the side windows.
5. To increase airflow to the outer panel vents, close the central panel
vents.
Do not place objects on top of the instrument panel as these
objects may become projectiles in a collision or sudden stop.

Temperature selection
The display window indicates the
selected temperature, function
(AUTO or one of the override
controls) and manual control of fan
speed (
) if automatic fan speed is not desired.
To control the temperature, select
any temperature between 18ÉC
(65ÉF) and 29ÉC (85ÉF) by pressing
the blue (cooler) or red (warmer)
buttons.
For continuous maximum cooling, push the blue button until 16ÉC
(60ÉF) is shown in the display window. The EATC will continue
maximum cooling (disregarding the displayed temperature) until a
warmer temperature is selected by pressing the red control.
For continuous maximum heating, push the red button until 32ÉC (90ÉF)
is shown in the display window. The EATC will continue maximum
heating (disregarding the displayed temperature) until a cooler
temperature is selected by pressing the blue control.
Temperature conversion
Press MAX A/C and DEF
at
the same time (for one second) to
switch between Fahrenheit and
Celsius.
If your vehicle has an English/Metric (E/M) control to change your
electronic instrument cluster display (if equipped) and the message
center display (if equipped) from English to Metric, this control will also
change the temperature display. Refer toElectronic Message Centerin

If the selected temperature is changed while the outside temperature is
displayed, the new temperature will be displayed for four seconds after it
is changed, then the outside temperature will return to the window.
If a manual override function is selected while the outside temperature is
displayed, the new function will be displayed for four seconds after it is
changed, then the outside temperature will return to the window along
with the override selection.
The outside temperature reading is most accurate when the vehicle is
moving. Higher readings may be obtained when the vehicle is not
moving. The readings that you get may not agree with temperatures
given on the radio due to differences in vehicle and station locations.
Operating tips
²In humid weather conditions, place the climate control system in DEF
before driving. This will reduce fogging on your windshield. Once the
windshield has been cleared, operate the climate control system as
desired.
²To reduce humidity buildup inside the vehicle in cold weather
conditions, don't drive with the climate control system in the OFF or
MAX A/C position.
²To reduce humidity buildup inside the vehicle in warm weather
conditions, don't drive with the climate control system in the OFF
position.
²Under normal weather conditions, your vehicle's climate control
system should be left in any position other than MAX A/C or OFF
when the vehicle is parked. This allows the vehicle to ªbreatheº
through the outside air inlet duct.
²Under snowy or dirty weather conditions, your vehicle's climate
control system should be left in the OFF position when the vehicle is
parked. This allows the climate control system to be free from
contamination of outside pollutants.
²If your vehicle has been parked with the windows closed during warm
weather conditions, the air conditioner will perform more efficiently in
cooling the vehicle if driven for two or three minutes with the
windows open. This will force most of the hot, stale air out of the
vehicle. Once the vehicle has been ªaired outº, operate the climate
control system as desired.

Driving while you tow
When towing a trailer:
²Ensure that you turn off your speed control. The speed control may
shut off automatically when you are towing on long, steep grades.
²Consult your local motor vehicle speed regulations for towing a trailer.
²Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
²Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
²Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
²Allow more distance for stopping with a trailer attached.
²If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
²The trailer tongue weight should be 10% of the loaded trailer weight.
²After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
²Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer's wheels.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Temporary spare tire information
Your vehicle may have a temporary or full-size spare tire. The temporary
spare tire for your vehicle is labeled as such. It is smaller than a regular
tire and is designed for emergency use only. Replace this tire with a
full-size tire as soon as possible.
If you use the temporary spare tire continuously or do not follow
these precautions, the tire could fail, causing you to lose control
of the vehicle, possibly injuring yourself or others.
Roadside Emergencies
166

JUMP STARTING YOUR VEHICLE
The gases around the battery can explode if exposed to flames,
sparks, or lit cigarettes. An explosion could result in injury or
vehicle damage.
Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time, the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
1.Use only a 12±volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle's electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect any electrical
surges. Turn all other accessories off.

WINDSHIELD WASHER FLUID
Washer fluid
Check the washer fluid whenever
you stop for fuel. The reservoir is
highlighted with a
symbol.
If the level is low, add enough fluid
to fill the reservoir. In very cold
weather, do not fill the reservoir all
the way.
Only use a washer fluid that meets Ford specification ESR-M17P5±A.
Refer toLubricant specificationsin this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle's paint finish, wiper blades or washer system.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait up to 10 minutes for the oil to drain into
the oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.

If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool, until the appropriate fill level is obtained.
Do not add engine coolant when the engine is hot. Steam and
scalding liquids released from a hot cooling system can burn you
badly. Also, you can be burned if you spill coolant on hot engine parts.
Do not put engine coolant in the windshield washer fluid
container. If sprayed on the windshield, engine coolant could
make it difficult to see through the windshield.
The cooling system in your vehicle is filled with either green-colored
Motorcraft Premium Engine Coolant meeting Ford specification
ESE-M97B44±A or yellow-colored Motorcraft Premium Gold Engine
Coolant meeting Ford Specification WSS-M97B51±A1. To determine your
vehicle's coolant type (color), check your coolant reservoir.
²Add Motorcraft Premium Engine Coolant (green-colored),
VC-4±A (U.S.) or CXC-10 (Canada) or Motorcraft Premium
Gold Engine Coolant (yellow-colored), VC-7±A, depending on
the type of coolant originally equipped in your vehicle.If you
are unsure which type of coolant your vehicle requires, check your
coolant reservoir or contact your local dealer.
²Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Speciality Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford specification WSS-M97B44±D
with the factory-filled coolant.Mixing Motorcraft Speciality Orange
Engine Coolant or any orange-colored extended life product with your
factory filled coolant can result in degraded corrosion protection.
Maintenance and Specifications

²A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
²Do not use alcohol, methanol or brine or any engine coolants
mixed with alcohol or methanol antifreeze (coolant).Alcohol
and other liquids can cause engine damage from overheating or
freezing.
²Do not add extra inhibitors or additives to the coolant.These
can be harmful and compromise the corrosion protection of the engine
coolant.
²Do not mix with recycled coolant unless from a Ford-approved
recycling process (seeUse of Recycled Engine Coolantsection).
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
water to the ªcold fullº level. For all other vehicles, which have a coolant
degas system with a pressurized cap, or if it is necessary to remove the
coolant pressure relief cap on the radiator of a vehicle with an overflow
system, follow these steps to add engine coolant.
To avoid personal injury, make sure the engine is cool before
unscrewing the coolant pressure relief cap. The cooling system is
under pressure; steam and hot liquid can come out forcefully when the
cap is loosened slightly.
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (an opaque plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture (see
above), to within the ªcold fill rangeº or the ªcold fullº level on the
