Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your dealer immediately.
Anti-lock brake system:
Illuminates indicating an ABS fault.
If the lamp stays on for more than a
few seconds, then an ABS fault is
indicated, have the system serviced
immediately. Normal braking is still functional unless the brake warning
light also is illuminated.
Check gage: Illuminates when any
of the following conditions has
occurred:
• The engine coolant temperature
is high.
• The engine oil pressure is low.
• The fuel gauge is at or near empty.
• The charging system is malfunctioning.
Air bag readiness: If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately. A chime will also
sound when a malfunction in the supplemental restraint system has been
detected.
Safety belt: Reminds you to fasten
your safety belt. A chime will also
sound to remind you to fasten your
safety belt.
Anti-theft system: Flashes when
the Securilock Passive Anti-theft
System has detected a fault.

Door ajar:Illuminates when the
ignition is in the ON position and
any door, trunk or the engine cover
is ajar.
Turn signal: Illuminates when the
left or right turn signal or the hazard
lights are turned on. If the indicators
stay on or flash faster, check the tail lamps for proper function.
High beams: Illuminates when the
high beam headlamps are turned on.
Defrost: Illuminates when the rear
window defroster is turned on.
Key-in-ignition warning chime: Sounds when the key is left in the
ignition in the OFF/LOCK or ACCESSORY position and the driver ’s door
is opened.
Headlamps on warning chime: Sounds when the headlamps or parking
lamps are on, the ignition is off (the key is not in the ignition) and the
driver ’s door is opened.
GAUGES
Engine coolant temperature
gauge: Indicates engine coolant
temperature. At normal operating
temperature, the needle will be
outside the red section. 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.
Tachometer: Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Engine oil pressure gauge:
Indicates engine oil pressure. If the
pointer drops to the red section
when the engine is running, stop
your vehicle as soon as possible,
shut off the engine and check the
oil tank level. Add oil if necessary.
Do not continue to operate your
engine as long as the pointer is in the red section. Otherwise, your
engine may be severely damaged.
If the gauge indicates zero or very low oil pressure (needle in the
red section) stop the vehicle and engine as soon as safe to do so
and check the engine oil tank level.
After running, the engine may be hot. Allow the engine to cool
before handling any components.
Voltmeter gauge: Measures the
battery charging voltage. If the
pointer moves above or below the
normal operating range under
normal vehicle operation, have your
vehicle ’s electrical system checked.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. Standard fill amount is 1
quart (0.9 L).
Only use a washer fluid that meets
Ford specification WSB-M8B16–A2.
Refer to Lubricant 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 40 °F (4.5 °C),
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.
3. Set the parking brake and ensure the gearshift is securely latched in 1
(First).

ENGINE COOLANT
Checking engine/intercooler coolant
The concentration and level of engine/intercooler coolant should be
checked at the mileage intervals listed in theScheduled Maintenance
Guide . The coolant concentration should be maintained at 50/50 coolant
and distilled water, which equates to a freeze point of -34°F (-36°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 bottom of the lower
baffle in the coolant reservoir. If the level falls below, add coolant per the
instructions in the Adding engine coolant section.
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:
• Freeze protection down to -34°F (-36°C).
• Boiling protection up to 265°F (129°C).
• Protection against rust and other forms of corrosion.
• Enables calibrated gauges to work properly.
