off-road operation. For this reason,
Mercury urges you to read and
understand the contents of the
Four-Wheelingsupplement.
Breaking in your vehicle
Your new vehicle goes through an
adjustment or breaking-in period
during the first 1,000 miles (1,600
km) of driving. During this period:
²Change your vehicle's speed
often as you drive. Do not drive
at one speed for a long time.
²Use only the type of engine oil
Ford recommends. Do not use
special ªbreak-inº oils.
²Avoid sudden stops. The
break-in period for brake linings
lasts for 1,600 km (1,000 miles)
of highway driving or 160 km
(100 miles) of city driving.

Introduction

Do not drive your vehicle
until you verify that the
brakelamps are working.
If your vehicle gets stuck in the
mud or snow it may be rocked out
of the spot. To rock the vehicle
out, shift between forward and
reverse gears in a steady rhythm.
Press lightly on the accelerator in
each gear. Do not rock the vehicle
for more than a few minutes,
because it could damage the
vehicle.
Do not spin the wheels at
over 55 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
ALL-WHEEL DRIVE (AWD)
SYSTEM (IF EQUIPPED)
Your vehicle is equipped with a
full-time All-Wheel Drive (AWD)
transfer case. Power is constantly
supplied to all four wheels through
a transfer case. The AWD system is
full-time and has no external
controls.
The AWD transfer case utilizes a
viscous clutch that distributes
torque to the front and rear
differentials (approximately 35%
front and 65% rear). The viscous
clutch is filled with a high viscosity
fluid; seeLubricant specifications
for more information.
All utility-type and AWD vehicles
have special design and equipment

features to make them capable of
performing in a wide variety of
off-road applications. Specific
design characteristics give them
higher centers of gravity than
ordinary passenger cars.
Utility and four-wheel
drive vehicles are NOT
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 or
abrupt maneuvers in these
vehicles.
DRIVING OFF ROAD WITH ALL-
WHEEL DRIVE (AWD)
Your vehicle is specially equipped
for driving on sand, snow, mud,
and rough terrain and has
operating characteristics that are
somewhat different from
conventional vehicles, both on and
off road. The following information
will help you learn to properly use
AWD.
When using AWD, maintain
steering wheel control at all times,
especially in rough terrain. Since
sudden changes in terrain can
result in abrupt steering wheel
motion, make sure you grip the
steering wheel from the outside.
Do not grip the spokes.
Drive cautiously to avoid vehicle
damage from concealed objects
such as rocks and stumps. You

should either know the terrain or
examine maps of the area before
driving. Map out your route before
driving in the area. For more
information on driving off-road,
readFour-Wheelingin your
owner's portfolio.
Sand
When driving over sand, try to
keep all four wheels on the most
solid area of the trail. Do not
reduce the tire pressures but shift
to a lower gear and drive steadily
through the terrain. Apply the
accelerator slowly and avoid
spinning the wheels.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capability may be limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle may stall.
Once through water, always try the
brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes.
Drying can be improved by moving
your vehicle slowly while applying
light pressure on the brake pedal.
After driving through mud, clean
off residue stuck to rotating
driveshafts and tires. Excess mud
stuck on tires and rotating
driveshafts causes an imbalance
