2003 FORD EXPLORER engine

Starting the engine
1. Turn the key to 3 (ON) without
turning the key to 4 (START). If
there is difficulty in turning the key,
rotate the steering wheel until the
key turns freely. This condition may
occur when:
•the front wheels are turned
•a front wheel is against the curb
Turn the key to 4 (START), then
release the key as soon as the engine starts. Excessive cranking could
damage the starter.
Note:If the engine does not start within five seconds on the first try,
turn the key to 1 (OFF/LOCK), wait 10 seconds and try again.
Cold weather starting (flexible fuel vehicles only)
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, you may
experience increased cranking times, rough idle or hesitation until the
engine has warmed up. Consult your fuel distributor for the availability of
winter grade ethanol.
Do not crank the engine for more than 30 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to OFF and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system (see Air
Cleaner decal). Such fluid could cause immediate explosive damage to
the engine and possible personal injury.
If you should experience cold weather starting problems on E
85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions
(flexible fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.

2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Using the engine block heater (if equipped)
An engine block heater warms the engine coolant which aids in starting
and heater/defroster performance. Use of an engine block heater is
strongly recommended if you live in a region where temperatures reach
-23°C (-10°F) or below. For best results, plug the heater in at least
three hours before starting the vehicle. The heater can be plugged in the
night before starting the vehicle.
To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by a qualified service technician. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an Anti-lock Braking System (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
Driving

Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
(IF EQUIPPED)
The AdvanceTrac
system provides a stability enhancement feature as
well as a traction enhancement feature. It helps your vehicle maintain
traction, when driving on slippery and/or hilly road surfaces, by detecting
and controlling wheel spin. Excessive wheel spin is controlled by
momentarily reducing engine power and rapidly applying the anti-lock
brakes. The system is a driver aid which makes your vehicle easier to
handle primarily on snow and ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
system off by pressing the AdvanceTrac
button.
This will allow your tires to“dig”for traction.
If the AdvanceTrac
system is activated excessively in a short period of
time, the brake portion of the system will shut down to allow the brakes
to cool down. A limited AdvanceTrac
function using only engine power
reduction will still help control the wheels from over-spinning. When the
brakes have cooled down, the system will again function normally.
Anti-lock braking is not affected by this condition and will function
normally during the cool-down period.
Driving
139

AdvanceTrac
enhances your vehicle’s stability during maneuvers that
require all available tire traction, like in wet/snowy/icy road conditions
and/or when performing emergency maneuvers. In an emergency
lane-change, the driver will experience better overall vehicle traction,
and have better control of the vehicle.
The AdvanceTrac
system helps the driver maintain steering control if
the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac
will attempt to correct the sliding motion by applying
brake force at individual tires and, if necessary, by reducing engine
power.
Driving conditions which may activate AdvanceTrac
include:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Hitting a patch of ice
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Hitting a curb while turning
•Driving on slick surfaces
•Cornering while towing a heavily loaded trailer (refer toTrailer
Towingin this chapter)
The AdvanceTrac
system automatically turns on when the engine is
started. However, the system does not function when the vehicle is
traveling in R (Reverse) or, if equipped with four-wheel drive, in 4L (4X4
LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the traction
enhancement feature will continue to function.
The AdvanceTrac
button allows
the driver to control the availability
of the AdvanceTrac
system.
AdvanceTrac
system status is
indicated by a warning indicator
light with a“sliding car”icon in the instrument cluster that will flash
when the system is active and an indicator light in the control button
that will illuminate when the system is turned off. In vehicles with a
message center, the message“ADVANCETRAC OFF”will be displayed.
If a failure is detected in the AdvanceTrac
system, the warning
indicator light in the instrument cluster will stay on. If the warning
Driving
140

indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the control once will disable the AdvanceTrac
stability
enhancement and the engine power reduction portion of the traction
enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the control for
more than five seconds will disable the AdvanceTrac
stability
enhancementandtraction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the
AdvanceTrac
system may be beneficial so the wheels are allowed to
spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the AdvanceTrac
stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
performs a system self-check. During AdvanceTrac

operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•The AdvanceTrac
indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTrac
operation.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTrac
system. Also, do not install a stereo
loudspeaker near the rear console or either rear seat. The
speaker vibrations can adversely affect the AdvanceTrac

sensors located in this area.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTrac
event
is an indication that at least some of the tires have exceeded their
ability to grip the road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.

STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an underinflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.
Your vehicle has larger tires and increased ground clearance, giving the
vehicle a higher center of gravity than a passenger car.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.

Driving with a 5–speed automatic transmission
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability, and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. 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. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
