2004 FORD EXPLORER brakes

Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine.
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.Driving through deep
water where the transmission vent tube is submerged may allow
water into the transmission and cause internal transmission
damage.
VEHICLE LOADING – WITH AND WITHOUT A TRAILER
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading
your vehicle, familiarize yourself with the following terms for determining
your vehicle’s weight ratings, with or without a trailer, from the vehicle’s
Safety Certification Label and Tire and Load Information Label:
Base Curb Weight– is the weight of the vehicle including a full tank of
fuel and all standard equipment. It does not include passengers, cargo, or
optional equipment.
Vehicle Curb Weight– is the weight of your new vehicle when you
picked it up from your dealer plus any aftermarket equipment.

GVWR (Gross Vehicle Weight
Rating)– is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the driver’s
door or door pillar. The GVW
must never exceed the GVWR.
Exceeding the Safety Certification Label axle weight rating limits
could result in substandard vehicle handling, performance,
engine, transmission and/or structural damage, serious damage to the
vehicle, loss of control and personal injury.
GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers weighing more than 680 kg
[1,500 lbs]).The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight– is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of

2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping company or an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Trailer towing with your vehicle may require the use of a trailer tow
option package.
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires, and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing procedure:
•Stay within your vehicle’s load limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
•Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter when figuring the total weight of your
vehicle.
Your vehicle is equipped with a standard Class II integrated hitch and
requires only a draw bar and ball with a 19 mm (3/4 inch) shank
diameter. An optional Class III/Class IV hitch is also available.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.

If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.
Never connect any trailer lighting to the vehicle’s taillamp
circuits, because it may damage the electrical system resulting in
fire. Contact your local Ford dealership for assistance in proper trailer
tow wiring installation. Additional electrical equipment may be
required.
Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Driving with a 5–speed automatic transmissionsection in this
chapter.)
•Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
2004 Explorer(exp)
Owners Guide (post-2002-fmt)
USA English(fus)
Driving
178

higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument cluster
chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
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
•Practice turning, stopping and backing up 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.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.

BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the “MAX” line
that do not trigger the brake system
warning lamp are within the normal
operating range, there is no need to
add fluid. If the fluid levels are
outside of the normal operating
range, the performance of your
brake system could be
compromised, seek service from your dealer immediately.
TRANSMISSION FLUID
Checking automatic transmission fluid
The automatic transmission does not have a transmission fluid dipstick.
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.
Transmission fluid should be checked and, if required, fluid
should be added by a qualified technician.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
