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 authorized dealer.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.
Airbag readiness:If this light fails
to illuminate when ignition is turned
to ON, continues to flash or remains
on, have the system serviced
immediately by your authorized dealer. A chime will also sound when a
malfunction in the supplemental restraint system has been detected.

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 miles (kilometers) of the vehicle.
•Without Message Center
To switch the display from Metric to
English, press and hold the button
on the cluster for three seconds.
•With Message Center
Refer toMessage Centerin the
Driver Controlschapter on how to
switch the display from Metric to
English and the odometer to the
speedometer.
Trip odometer:Registers the miles (kilometers) of individual journeys.
•Without Message Center
Press and release the button on the
cluster to toggle between odometer
and trip odometer display. To reset,
press the button again until the trip
reading is 000000.0 miles.

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 to
Lubricant 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.
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.
CHANGING THE WIPER BLADES
1. Pull the wiper blade and arm
away from the glass. Turn the blade
at a right angle to the arm. Push the
lock tab (A) to release the blade
from the arm loop and pull the
blade down toward the windshield
to remove it from the arm.
2. Attach the new blade to the arm
loop and pull it into place until a
click is heard.
Replace wiper blades at least once per year for optimum performance.

•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
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 -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 “FULL COLD” level or within the “COLD
FILL RANGE” 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:
•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.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor 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 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.
