2002 FORD EXPLORER battery

DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to the scheduled maintenance guide for maintenance
intervals. If the original universal joints are replaced with universal joints
equipped with grease fittings, lubrication will also be necessary.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.
However, for severe usage or in high temperature climates, check the
battery electrolyte level. Refer to the scheduled maintenance guide for
the service interval schedules.
Keep the electrolyte level in each cell up to the ªlevel indicatorº.
Do not overfill the battery cells.
If the electrolyte level in the battery is low, you can add plain tap water
to the battery, as long as you do not use hard water (water with a high
mineral or alkali content). If possible, however, try to only fill the battery
cells with distilled water. If the battery needs water often, have the
charging system checked.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
Maintenance and care
251

Batteries normally produce explosive gases which can cause
personal injury. Therefore, do not allow flames, sparks or lighted
substances to come near the battery. When working near the battery,
always shield your face and protect your eyes. Always provide proper
ventilation.
When lifting a plastic-cased battery, excessive pressure on the
end walls could cause acid to flow through the vent caps,
resulting in personal injury and/or damage to the vehicle or battery.
Lift the battery with a battery carrier or with your hands on opposite
corners.
Keep batteries out of reach of children. Batteries contain sulfuric
acid. Avoid contact with skin, eyes or clothing. Shield your eyes
when working near the battery to protect against possible splashing of
acid solution. In case of acid contact with skin or eyes, flush
immediately with water for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a physician immediately.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
Because your vehicle's engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the
engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
²The vehicle may need to be driven to relearn the idle and fuel trim
strategy.
Maintenance and care
252

²If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
²Always 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.
WINDSHIELD WIPER BLADES
Check the wiper blades at least twice a year or when they seem less
effective. Substances such as tree sap and some hot wax treatments used
by commercial car washes reduce the effectiveness of wiper blades.
Checking the wiper blades
If the wiper blades do not wipe properly, clean both the windshield and
wiper blades using undiluted windshield wiper solution or a mild
detergent. Rinse thoroughly with clean water. To avoid damaging the
blades, do not use fuel, kerosene, paint thinner or other solvents.

Readiness for Inspection/Maintenance (I/M) testing
In some localities, it may be a legal requirement to pass an I/M test of
the on-board diagnostics system. If your ªCheck Engine/Service Engine
Soonº light is on, refer to the description in theWarning Lights and
Chimessection of theInstrumentationchapter. Your vehicle may not
pass the I/M test with the ªCheck Engine/Service Engine Soonº light on.
If the vehicle's powertrain system or its battery has just been serviced,
the on-board diagnostics system is reset to a ªnot ready for I/M testº
condition. To ready the on-board diagnostics system for I/M testing, a
minimum of 30 minutes of city and highway driving is necessary as
described below:
²First, at least 10 minutes of driving on an expressway or highway.
²Next, at least 20 minutes driving in stop-and-go, city-type traffic with
at least four idle periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once started,
do not turn off the engine until the above driving cycle is complete.
BULBS
Replacing exterior bulbs
Check the operation of the following lamps frequently:
²Headlamps
²Foglamps
²High-mount brakelamp
²Brakelamps
²Turn signals
²License plate lamp
²Tail lamps
²Back-up lamps
Do not remove lamp bulbs unless they can be replaced immediately with
new ones. If a bulb is removed for an extended period of time,
contaminants may enter the lamp housings and affect lamp performance.
