1998 Mercury Mountaineer Owner's Manuals

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 or
abrupt maneuvers in these
vehicles.
Using the Control-Trac system
Shifting between 4WD AUTO
and 4WD HIGH
When you move the control to
4WD HIGH, the indicator light will
illuminate in the instrument
cluster. When you move the
control to 4WD AUTO, the
indicator light will turn off.
Either shift can be done at a stop
or while driving at any speed.
Shifting from 4WD AUTO or
4WD HIGH to 4WD LOW
1. Bring the vehicle to a stop.
2. Depress the brake.
3. Place the gearshift in N
(Neutral) (automatic transmission)
or depress the clutch (manual
transmission).
4. Move the 4WD control to the
4WD LOW position.

1. Bring the vehicle to a stop.
2. Depress the brake.

Driving off-road with 4WD
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 the road.
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, read the ªFour Wheelingº
supplement in your owner's
portfolio.HIGH

If your vehicle gets stuck
If the vehicle is stuck, shift the
transmission in a steady motion
between forward and reverse
gears. Allow the transmission to
engage, then press lightly on the
accelerator.
Do not rock the vehicle for
more than a few minutes. The
transmission and tires may be
damaged or the engine can
overheat.
Do not spin the wheels at
over 56 km/h (35 mph).
The tires may fail and injure a
passenger or bystander.
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.
Driving
115

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
that could damage drive
components.
If the transmission and transfer
case are submerged in water, their
fluids should be checked and
changed, if necessary.
Water intrusion into the
transmission may damage the
transmission.
If the rear axle is submerged in
water, the rear axle lubricant
should be checked and changed, if
necessary. The rear axle is filled
with a synthetic lubricant and does
not normally require a lubricant
change for the life of the vehicle.
Rear axle lubricant quantities
should not need to be checked
unless a leak is suspected.
Driving on hilly or sloping
terrain
When driving on a hill, avoid
driving crosswise or turning on
steep slopes. You could lose
traction and slip sideways. Drive
straight up, straight down or avoid
the hill completely. Know the
conditions on the other side of a
Driving
116

hill before driving over the crest.
When climbing a steep hill, start in
a lower gear rather than
downshifting to a lower gear from
a higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of
stalling.
When descending a steep hill,
avoid sudden braking. Rapid
pumping of the brake pedal will
help slow the vehicle and still
maintain steering control.
When speed control is on and you
are driving uphill, your vehicle
speed may drop considerably,
especially if you are carrying a
heavy load.
If vehicle speed drops more than
16 km/h (10 mph), the speed
control will cancel automatically.
Resume speed with accelerator
pedal.
If speed control cancels after
climbing the hill, reset speed by
pressing and holding the SET
ACCEL button (to resume speeds
over 50 km/h (30 mph).
Automatic transmissions 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.
Driving
117

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.
ALL WHEEL DRIVE (AWD)
SYSTEM (IF EQUIPPED)
(5.0L ENGINES ONLY)
Your vehicle is equipped with a
full-time All Wheel Drive (AWD)
transfer case. Power is supplied to
all four wheels all the time with no
need to shift between two-wheel
drive and four-wheel drive.
For the lubricant specification and
refill capacity of the AWD transfer
case refer toCapacities and
specificationschapter.
