when the oil pressure falls below the
normal range. Check the oil level
and add oil if needed. Refer to
Engine oilin theMaintenance and Specificationschapter.
Engine coolant temperature:Illuminates when the engine coolant
temperature is high. Stop the vehicle as soon as possible, switch off the
engine and let cool. Refer toEngine coolantin theMaintenance and
Specificationschapter.
²Standard instrument cluster
²Optional instrument cluster
Never remove the coolant reservoir cap while the engine is
running or hot.
Low tire pressure warning:
Illuminates when your tire pressure is
low. If the light remains ON at start
up or while driving, the tire pressure
should be checked. Refer to
Inspecting and Inflating Your Tiresin theTires, Wheels and Loading
chapter. When the ignition is first turned to ON, the light will illuminate for
3 seconds to ensure the bulb is working. If the light does not turn ON,
have the system inspected by your authorized dealer. For more information
on this system, refer toUnderstanding Your Tire Pressure Monitoring
Systemin theTires, Wheels and Loadingchapter.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Ford specification WSB-M8B16±A2.
Do not use any special washer fluid such as windshield water repellent
type fluid or bug wash. They may cause squeaking, chatter noise,
streaking and smearing. Refer toLubricant specificationslater in 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.
If you operate your vehicle in temperatures below 40É F (4.5ÉC),
use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
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.

If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
²Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34ÉF (-36ÉC). 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 ªFULL COLDº level in the coolant reservoir.
If the level falls below, add coolant per the instructions in theAdding
engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50±50 mixture of coolant and water provides the following:
²Freeze protection down to -34ÉF (-36ÉC).
²Boiling protection up to 265ÉF (129ÉC).
²Protection against rust and other forms of corrosion.
²Enables calibrated gauges to work properly.
When the engine is cold, check the level of the engine coolant in the
reservoir.

²4.0L V6 engine
²4.6L V8 engine
²The engine coolant should be at the ªFULL COLDº level as listed on
the engine coolant reservoir (depending upon application).
²Refer toscheduled maintenance informationfor service interval
schedules.
²Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
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.
²Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7±A (U.S., except CA, OR and NM),
VC-7±B (CA, OR and NM), meeting Ford Specification
WSS-M97B51±A1.
Note:Use of Motorcraft Cooling System Stop Leak Pellets, VC-6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
²Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, VC-2 (US) or
CXC-209 (Canada), meeting Ford specification WSS-M97B44±D
with the factory-filled coolant.Mixing Motorcraft Specialty Orange
Engine Coolant or any orange-colored extended life product with your
factory filled coolant can result in degraded corrosion protection.
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, 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.
