Engine coolant
temperature gauge:
Indicates engine
coolant temperature. At
normal operating temperature, the needle will be in
the normal range (between“H”and“C”). If it enters
the red section, the engine is overheating. Stop the
vehicle as soon as safely possible, switch off the
engine and let the engine cool.
Never remove the coolant reservoir cap
while the engine is running or hot.
Odometer:Registers
the total kilometers
(miles) of the vehicle.
Trip odometer:
Registers the
kilometers (miles) of
individual journeys.
Press and release the
reset button until a“T”
appears in the display.
Press and hold the button for three seconds to reset.

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. Refer toLubricant specifications
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 4.5°C (40°F), 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.
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 5 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) (automatic
transmissions) or 1 (First) (manual transmissions).

•Always 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 mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36°C (-34°F).
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
“cold full”of“cold fill range”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.A50–50 mixture of coolant and
water provides the following:
•freeze protection down to -36°C (-34°F)
•boiling protection up to 129°C (265°F)
•protection against rust and other forms of
corrosion
•enables calibrated gages to function properly

When the engine is cold, check the level of the
engine coolant in the reservoir.
•The engine coolant should be at the“cold fill
level”as listed on the engine coolant reservoir.
•Refer to the scheduled maintenance guide for
service interval schedules.
•Be 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 to
Adding 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.

Add Motorcraft Premium Gold Engine Coolant
(yellow-colored), VC-7–A (VC-7–B in Oregon),
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.
•
Do 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.
