Optional instrument cluster gauges
Speedometer
Indicates the current vehicle speed.
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 engine immediately and let the
engine cool. Refer toEngine
coolantin theMaintenance and
carechapter.
Never remove the coolant reservoir cap while the engine is
running or hot.

LOW OIL PRESSURE.Displayed when the engine oil level is low. If
this warning message is displayed, check the level of the engine oil.
Refer toEngine oilin theMaintenance and carechapter for
information about adding engine oil.
CHECK ENGINE TEMP.Displayed when the engine coolant is
overheating. Stop the vehicle as soon as safely possible, turn off the
engine and let it cool. Check the coolant and coolant level. Refer to
Engine coolantin theMaintenance and carechapter. If the warning
stays on or continues to come on, contact your dealer as soon as safely
possible.
CHECK CHARGING SYSTEM.Displayed when the electrical system is
not maintaining proper voltage. If you are operating electrical accessories
when the engine is idling at a low speed, turn off as many of the
electrical loads as soon as possible. If the warning stays on or comes on
when the engine is operating at normal speeds, have the electrical
system checked as soon as possible.
TRANSMISSION OVERHEATED.Indicates the transmission is
overheating. This warning may appear when towing heavy loads or when
driving in a low gear at a high speed for an extended period of time.
Stop the vehicle as soon as safely possible, turn off the engine and let it
cool. Refer toTransmission fluidin theMaintenance and care
chapter. If the warning stays on or continues to come on, contact your
dealer for transmission service as soon as possible.

Cold weather starting (flexible fuel vehicles only)
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, you may
experience increased cranking times, rough idle or hesitation until the
engine has warmed up. Consult your fuel distributor for the availability of
winter grade ethanol.
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner Decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
If you should experience cold weather starting problems on ethanol, and
neither an alternative brand of ethanol nor an engine block heater is
available, the addition of unleaded gasoline to your tank will improve
cold starting performance. Your vehicle is designed to operate on ethanol
alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and carechapter for
more information on diesel fuel.
If the engine fails to start using the preceding instructions
1. Press the accelerator pedal 1/3 to 1/2 of the way to floor and hold.
2. Turn the key to START position.
3. When the engine starts, release the key, then release the accelerator
pedal gradually as the engine speeds up.
4. If the engine still fails to start, repeat steps one through three.
5. After the engine starts, hold your foot on the brake pedal, put the
gearshift lever in gear and release the parking brake. Slowly release the
brake pedal and drive away in a normal manner.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant, which improves
starting, warms up the engine faster and allows the heater-defroster
system to respond quickly. Use of an engine block heater is strongly
recommended if you live in a region where temperatures reach -23ÉC
(-10ÉF) or below.

WINDSHIELD WASHER FLUID
Checking and adding 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 specifications. Refer to
Lubricant specificationsin theCapacities and specificationschapter.
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.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
mileage intervals listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and water, which
equates to a freeze point of -34É F (-36É C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014±R1060). The level of coolant
should be maintained at the ªcold fullº of ªcold fill rangeº level in the
coolant reservoir. If the level falls below, add coolant per the instructions
in the Adding Engine Coolant section.
