ACCEL button (to resume speeds
over 50 km/h (30 mph).
Automatic transmission may shift
frequently while driving up steep
grades. Eliminate frequent shifting
by shifting out of
(Overdrive)
into D (Drive).
Driving on snow and ice
A 4WD vehicle has advantages
over 2WD vehicles in snow and ice
but can skid like any other vehicle.
Avoid sudden applications of
power and quick changes of
direction on snow and ice. Apply
the accelerator slowly and steadily
when starting from a full stop.
When braking, apply the brakes as
you normally would. In order to
allow the anti-lock brake system
(ABS) to operate properly, keep
steady pressure on the brake
pedal.
Allow more stopping distance and
drive slower than usual. Consider
using one of the lower gears.
DRIVING THROUGH WATER
Do not drive quickly through
standing water, especially if the
depth is unknown. Traction or
brake capability may be limited
and if the ignition system gets wet,
your engine may stall. Water may
also enter your engine's air intake
and severely damage your engine.
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of

is properly attached to your
vehicle. See your dealer or a
reliable trailer dealer if you require
assistance.
If your vehicle is not equipped
with the factory heavy duty trailer
tow option, auxiliary coolers are
recommended for the automatic
transmission system if you are
planning on:
²traveling farther than 80 km
(50 miles)
²towing in hilly terrain
²towing frequently
Hitches
Do not use hitches that clamp onto
the vehicle's bumper or attach to
the axle. You must distribute the
load in your trailer so that 10 to
15% of the total weight of the
trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a
load equalizing hitch, always use
the following procedure:
1. Park the unloaded vehicle on a
level surface. With the ignition on
and all doors closed, allow the
vehicle to stand for several
minutes so that it can level.
2. Turn the air suspension (if
equipped) control to OFF.
3. Measure the height of a
reference point on the front and
rear bumpers at the center of the
vehicle.

²Depress hazard lights control to
activate all hazard flashers
simultaneously.
²Depress control again to turn
the flashers 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 ªFuel Resetº
indicator light will illuminate in the
instrument cluster. 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 the 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

The gases around the
battery can explode if
exposed to flames, sparks, or lit
cigarettes. An explosion could
result in injury or vehicle
damage.
Do not push start your
vehicle. You could damage
the catalytic converter.

Also see the label on the battery.
1. Use only a 12±volt supply to
start your vehicle. If you connect
your battery to a 24±volt power
supply you can damage your
starter, ignition system and other
electrical components.
2. Do not disconnect the battery of
the disabled vehicle as this could
damage the vehicle's electrical
system.

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.
Changing the wiper blades
When replacing wiper blade
assemblies, always use a
Motorcraft part or equivalent. To
make replacing the wipers easy,
turn the ignition to ACC, then turn
the wipers on. When the wipers
reach the vertical position, turn
the ignition to LOCK.
To replace the wiper blades:

3. After at least three to five fuel
tank fill-ups, fill the fuel tank and
record the current mileage
reading.
4. Use one of the following
equations to calculate fuel
economy.
Liters used x 1004Total
kilometers traveled
Total miles traveled4Total
gallons used
Keep a record for at least one
month. This will provide an
accurate estimate of the vehicle's
fuel economy.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with
various emission control
components and a catalytic
converter which will enable your
vehicle to comply with applicable
exhaust emission standards. To
make sure that the catalytic
converter and other emission
control components continue to
work properly:
²Use only unleaded fuel.
²Avoid running out of fuel.
²Do not turn off the ignition
while your vehicle is moving,
especially at high speeds.
²Have the services listed in your
ªService Guideº performed
according to the specified
schedule.
