1997 FORD EXPLORER engine

Important safety precautions
A computer system controls the
engine's idle revolutions per
minute (RPM). When the engine
starts, the idle RPM runs faster to
warm the engine. If the engine idle
speed does not slow down
automatically, have the vehicle
checked. Do not allow the vehicle
to idle for more than ten minutes.
Extended idling at high
engine speeds can produce
very high temperatures in the
engine and exhaust system,
creating the risk of fire or other
damage.
Do not park, idle, or drive
your vehicle in dry grass
or other dry ground cover. The
emission system heats up the
engine compartment and exhaust
system, which can start a fire.
Do not start your vehicle
in a closed garage or in
other enclosed areas. Exhaust
fumes can be toxic. Always open
the garage door before you start
the engine. SeeGuarding
against exhaust fumesin this
chapter for more instructions.

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 in an open area
for long periods of time, open the
windows at least 2.5 cm (one
inch).
Adjust the heating or air
conditioning to bring in fresh air.

Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.
Guarding against exhaust
fumes
Although odorless and colorless,
carbon monoxide is present in
exhaust fumes. Take precautions
to avoid its dangerous effects.
If you ever smell exhaust
fumes of any kind inside
your vehicle, have your dealer
inspect and fix your vehicle
immediately. Do not drive if you
smell exhaust fumes. These
fumes are harmful and could kill
you.
Have the exhaust and body
ventilation systems checked
whenever:
²the vehicle is raised for service
²the sound of the exhaust system
changes
²the vehicle has been damaged in
a collision

When starting a fuel-injected
engine, avoid pressing the
accelerator before or during
starting. Only use the accelerator
when you have difficulty starting
the engine. For more information
on starting the vehicle, refer to
Starting the vehiclein this
chapter.
Before starting the vehicle:
1. Make sure all vehicle occupants
have buckled their safety belts. For
more information on safety belts
and their proper usage, refer to
theSeating and safety restraints
chapter.
2. Make sure the headlamps and
vehicle accessories are off.

accelerator and start the engine
while holding the accelerator
down. Release accelerator when
engine starts.
4. After idling for a few seconds,
apply the brake and release the
parking brake.
Using the engine block heater
(if equipped)
An engine block heater warms the
engine coolant, which improves
starting, warms up the engine
faster and allows the
heater-defroster system to respond
quickly. They are strongly
recommended if you live in a
region where temperatures reach
Ð23ÉC (±10ÉF) or below.
For best results, plug the heater in
at least three hours before starting
the vehicle. Using the heater for
longer than three hours will not
harm the engine, so 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.

UNDERSTANDING THE
TRACTION-LOKTREAR AXLE
(IF EQUIPPED)
This axle provides added traction
on slippery surfaces, particularly
when one or more wheels are on a
surface with poor traction.
Extended use of other than
matching size tires on a
Traction-Loktrear axle could
result in a permanent reduction in
effectiveness. This loss of
effectiveness does not affect
normal driving and should not be
noticeable to the driver.
To avoid injury, never run
the engine with one wheel
off the ground, such as when
changing a tire.
AUTOMATIC RIDE CONTROL
SYSTEM (IF EQUIPPED)
The Automatic Ride Control
System is designed to improve
ride, handling and general vehicle
performance for both on and
off-road conditions by adjusting
vehicle ride height and shock
dampening (firm or soft).
The system automatically controls
vehicle ride height over a range
based on vehicle speed and the
selections of four wheel drive
modes or the Ride Control switch.
The system keeps the vehicle at a
constant level if a load is added or
removed from the vehicle. Shock
dampening is automatically set

the brake pedal is depressed. If
you cannot move the gearshift
lever from P (Park) with the brake
pedal depressed:
1. Apply the parking brake.
2. Turn the ignition key to Lock,
then remove the key.
3. Insert the key and turn the
ignition off.
4. Apply the brake pedal and shift
into N (Neutral).
5. Start the vehicle.
If it is necessary to use this
procedure to move the gearshift
lever , it is possible that a fuse
may have blown and the vehicle's
brakelamps may not be working.
