²Allow more room for stopping
with a trailer attached.
²Practice turning, stopping and
backing in an area before
starting on a trip to get the feel
of the vehicle/trailer
combination.
²When turning, drive slightly
beyond the normal turning point
so the trailer wheels will clear
curbs and other obstacles.
²When stopped in traffic for long
periods of time in hot weather,
place the automatic transmission
gearshift in P (Park) to increase
idle speed. 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.
²After you have travelled about
80 km (50 miles), thoroughly
check your hitch, electrical
connections and trailer wheel
lug nuts.
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 (six inches)
above the bottom edge of the
rear bumper.

HAZARD LIGHTS CONTROL
Use only in an emergency to warn
traffic of vehicle breakdown,
approaching danger, etc. Depress
to activate all indicators
simultaneously. Depress again to
switch off. The warning lights can
be operated when the ignition is
off.
FUEL PUMP SHUT-OFF SWITCH
If the engine cranks but does not
start after a collision, the fuel
pump shut±off switch may have
been activated. The shut±off
switch is a device intended to stop
the electric fuel pump when your
vehicle has been involved in a
substantial jolt.
1. Turn the ignition switch to the
OFF position.
2. Check fuel system for leaks.
3. If no fuel leak is apparent, reset
the fuel pump shut-off switch by
pushing in the button on the
switch.
4. Turn the ignition switch to the
ON position. Pause for a few
seconds and return the key to the
OFF position.
5. Make a further check for leaks

SERVICING YOUR VEHICLE
Service recommendations
To help you service your vehicle:
²We highlight do-it-yourself items
in the engine compartment for
easy location.
²As possible, we design parts that
can be replaced without tools.
²We provide you with a ªService
Guideº which makes tracking
routine service for your vehicle
easy.
If your vehicle requires
professional service, your
dealership can provide necessary
parts and service. Check your
ªWarranty Information Bookletº to
find out which parts and services
are covered.
Use only recommended fuels,
lubricants, fluids and service parts
conforming to specifications.
Motorcraft parts are designed and
built to provide the best
performance in your vehicle.
Precautions when servicing
your vehicle
Be especially careful when
inspecting or servicing your
vehicle. Here are some general
precautions for your safety:
²Do not work on a hot engine.
²If you must work with the
engine running, avoid wearing
loose clothing or jewelry that

cooling mode. If the engine coolant
supply is depleted, this feature
allows the driver to drive the
vehicle (with limited power) for a
short distance in order to get the
vehicle to a service facility. Take
your vehicle to a service facility as
soon as possible to minimize
engine damage.
The actual distance your vehicle
can be driven depends on vehicle
load, road conditions and outside
temperature.
How fail-safe cooling works
If the engine overheats, the engine
will automatically switch from
eight to alternating four cylinder
operation. Each disabled cylinder
acts as an air pump and cools the
engine.
When this occurs, the engine
coolant temperature gauge will
move into the red area and the
light illuminates.
The
CHECK
ENGINElight will illuminate,
indicating that vehicle service is
required.
The vehicle will still operate, but
will have limited engine power and
no air conditioning capability.
Continued operation will increase
engine temperature and cause the
engine to completely shut down.
The vehicle will coast to a stop.
As the engine temperature cools,
the engine may be re-started. Take
your vehicle to a service facility as

Maintenance and care
171

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.
If you smell exhaust fumes
inside your vehicle, have
your dealer inspect your vehicle
immediately. Do not drive if you
smell exhaust fumes.
On vehicles without
original equipment floor
covering or insulation, do not let
passengers ride in your truck in
a manner that allows contact
between skin and the metal floor.
If you notice one or more of the
following, the emissions system
may not be working properly. Have
your vehicle serviced as soon as
possible.
²Fluid leaks
²The
orCHECK
ENGINElights
illuminate in the instrument
cluster and remain lit
²Strange odors
²Engine runs more than five
seconds after shut-off or engine
misfires, surges, stalls or
backfires
²Loss of oil pressure.
