2002 FORD EXPLORER engine

Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
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:
²Stay within your vehicle's load limits.
²Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
²Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
²Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
²Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
²Refer 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. Remember to figure in the tongue
load of your loaded vehicle when figuring the total weight.
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.

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
control, and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that 10% of
the total weight of the trailer is on the tongue.
Safety chains
Always connect the trailer's safety chains to the frame or hook retainers
of the vehicle. To connect the trailer's safety chains, cross the chains
under the trailer tongue and allow slack for turning corners.
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.

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) (automatic transmissions) or N (Neutral)
(manual transmissions). 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.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
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.
Recreational towing (all wheels on the ground)
Follow these guidelines for your specific powertrain combination to tow
your vehicle with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.

approaching danger, etc. The hazard flashers can be operated when the
ignition is off.
²The hazard lights control is
located on top of the steering
column.
²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn the
flashers off.
RESETTING THE FUEL PUMP SHUT-OFF SWITCH
FUEL

The fuel pump shut-off switch is a device intended to stop the electric
fuel pump when your vehicle has been involved in a substantial jolt.
After a collision, if the engine cranks but does not start, the fuel pump
shut-off switch may have been activated.

Power distribution box
The power distribution box is
located in the engine compartment.
The power distribution box contains
high-current fuses that protect your
vehicle's main electrical systems
from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and carechapter.

3. Turn the wrench
counterclockwise until tire is
lowered to the ground making sure
the other end of the wrench does
not scuff kick plate, the tire can be
slid rearward and the cable is
slightly slack.
4. Lift tire on one side and remove
the retainer from the spare tire.
Tire change procedure
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
Refer to the tire changing instruction sheet for detailed tire change
instructions.
1. Park on a level surface, activate
hazard flashers and set the parking
brake.
2. Place gearshift lever in P (Park)
or in the reverse gear (manual
transmission) and turn engine OFF.
