BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle's
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
cold, heat, moisture, road dust, salt or mud. If a
ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking,
the brake linings may be worn-out and should be
inspected by a qualified service technician.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle's anti-lock brake system. The ABS performs a
self-check at 17 km/h (10 mph) after you start the
engine and begin to drive away. A brief mechanical
noise may be heard during this test. This is normal.
If a malfunction is found, the ABS warning light will
come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the
vehicle should be inspected by a qualified service
technician.

Servicing after towing
If you tow a trailer for long distances, your vehicle
will require more frequent service intervals. Refer to
your Scheduled Maintenance guide for more
information.
Trailer towing tips
²Practice turning, stopping and backing up in an
area before starting on a trip to get the feel of the
vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs
and other obstacles.
²Allow more distance for stopping with a trailer
attached.
²The trailer tongue weight should be 10% of the
loaded trailer weight.
²After you have traveled 80 km (50 miles),
thoroughly check your hitch, electrical
connections and trailer wheel lug nuts.
²When stopped in traffic for long periods of time in
hot weather, place the gearshift in P (Park) and
increase idle speed. This aids engine cooling and
air conditioner efficiency.
²Vehicles with trailers should not be parked on a
grade. If you must park on a grade, place wheel
chocks under the trailer's wheels.
DRIVING THROUGH WATER
Do not drive quickly through standing water,
especially if the depth is unknown. Traction or brake
capability may be limited and if the ignition system
gets wet, your engine may stall. Water may also
enter your engine's air intake and severely damage
your engine.
If driving through deep or standing water is
unavoidable, proceed very slowly. Never drive
through water that is higher than the bottom of the
hubs.

Engine oil and filter recommendations
Look for this
certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline
engines by the American Petroleum Institute.
Do not use supplemental engine oil additives, oil
treatments or engine treatments. They are
unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your
warranty.
Change your engine oil and filter according to the
appropriate schedule listed in the Scheduled
Maintenance Guide.
Ford production and aftermarket (Motorcraft) oil
filters are designed for added engine protection and
long life. If a replacement oil filter is used that does
not meet Ford material and design specifications,
startup engine noises or knock may be experienced.
It is recommended you use the appropriate
Motorcraft oil filter (or another brand meeting Ford
specifications) for your engine application.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and refilled as
needed. Refer to the Scheduled Maintenance Guide
for the service interval schedules:
Maintenance and care

If the engine coolant has not been checked at the
recommended interval, the engine coolant reservoir
may become empty. If this occurs, add engine
coolant to the coolant reservoir. For more
information on engine coolant maintenance, refer to
Adding engine coolantin this chapter.
Automotive fluids are not interchangeable; do not
use engine coolant, antifreeze or windshield washer
fluid outside of its specified function and vehicle
location.
Maintenance and care
137

Change your engine coolant according to the
appropriate schedule listed in the Scheduled
Maintenance Guide.
Before adding engine coolant, check the color of the
coolant in your vehicle.
For vehicles with green coolant,use Ford
Premium Cooling System Fluid E2FZ-19549±AA (in
Canada, Motorcraft CXC-8±B) or an equivalent
premium engine coolant that meets Ford
specification ESE-M97B44±A.
Do not add orange coolant or recycled coolant
to your vehicle originally equipped with
conventional green coolant.
For vehicles with orange coolant,use Ford
Extended Life Engine Coolant F6AZ-19544±AA or a
DEX-COOLtequivalent that meets Ford
specification WSS-M97B44±D.
Do not add conventional green coolant or
recycled coolant to your vehicle originally
equipped with orange coolant.
Do not use alcohol or methanol antifreeze or any
engine coolants mixed with alcohol or methanol
antifreeze. Do not use supplemental coolant
additives in your vehicle. These additives may harm
your engine cooling system. The use of an improper
coolant may void your warranty of your vehicle's
engine cooling system.
Recycled engine coolant
Ford Motor Company recommends that Ford and
Lincoln-Mercury dealers use recycled engine coolant
produced by Ford-approved processes.
For vehicles with green coolant,not all coolant
recycling processes produce coolant which meets
Ford specification ESE-M97B44±A, and use of such
coolant may harm engine and cooling system
components.
Maintenance and care
139

For vehicles with orange coolant,no recycling
process has been approved at this time and use of
such coolant may harm engine and cooling system
components.
Always dispose of used automotive fluids in a
responsible manner. Follow your community's
regulations and standards for recycling and disposing
of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle's cooling
system can hold, refer toRefill capacitiesin the
Capacities and specificationschapter.
Have your dealer check the engine cooling system
for leaks if you have to add more than 1.0 liter
(1.0 quart) of engine coolant per month.
Severe winter climate
If you drive in extremely cold climates (less than
±36ÉC [±34ÉF]), it may be necessary to increase the
coolant concentration above 50%. Refer to the chart
on the coolant container to ensure the coolant
concentration in your vehicle is such that the
coolant will not freeze at the temperature level in
which you drive during winter months. Never
increase the engine coolant concentration above
60%. Leave a 50/50 mixture of engine coolant and
water in your vehicle year-round in non-extreme
climates.
CHECKING AND ADDING POWER STEERING
FLUID
Check the power steering fluid. Refer to the
Scheduled Maintenance Guide for the service
interval schedules. If adding fluid is necessary, use
only MERCONtV ATF.
Maintenance and care
140

If your vehicle is
equipped with a 4.6L
V8 engine,check the
power steering fluid
level with the engine at
ambient temperature.
Allow at least one-half
hour after driving for
the power steering
fluid to cool.
1. Start the engine and
allow the engine to
idle.
2. Turn the steering
wheel left and right
several times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be
between the MIN and MAX lines. Do not add fluid if
the level is within this range.
5. If the fluid is low, add fluid in small amounts,
continuously checking the level until it reaches the
correct operating range. Be sure to put the cap back
on the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid
Refer to your Scheduled Maintenance Guide for
scheduled intervals for fluid checks and changes.
Your transmission does not consume fluid. However,
the fluid level should be checked if the transmission
is not working properly, i.e., if the transmission slips
or shifts slowly or if you notice some sign of fluid
leakage.
Automatic transmission fluid expands when warmed.
To obtain an accurate fluid check, drive the vehicle
until it is at normal operating temperature
(approximately 30 km [20 miles]). If your vehicle has
