rather than attempt a sudden
return to the pavement which
could cause the vehicle to slide
sideways out of control or
rollover. Remember, your safety
and the safety of others should
be your primary concern.
Emergency maneuvers
²In an unavoidable emergency
situation where a sudden sharp
turn must be made, remember
to avoid ªover-drivingº your
vehicle, i.e., turn the steering
wheel only as rapidly and as far
as required to avoid the
emergency. Excessive steering
will result in less vehicle control,
not more. Additionally, smooth
variations of the accelerator
and/or brake pedal pressure
should be utilized if changes in
vehicle speed are called for.
Avoid abrupt steering,
acceleration or braking. Use all
available road surface to return
the vehicle to a safe direction of
travel.
²In the event of an emergency
stop, avoid skidding the tires
and do not attempt any sharp
steering wheel movements.
²If the vehicle goes from one
type of surface to another (i.e.,
from concrete to gravel) there
will be a change in the way the
vehicle responds to a maneuver
(steering, acceleration or
barking). Again, avoid these
abrupt inputs.
4WD or AWD operation on the road

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. To maintain
steering and braking control of
your vehicle, you must have all
four wheels on the ground and
they must be rolling, not sliding or
spinning.
Sand
When driving over sand, try to
keep all four wheels on the most
solid area of the trail. Avoid
reducing the tire pressure. Instead,
shift to a lower gear and drive
steadily through the terrain. Apply
the accelerator slowly and avoid
spinning the wheels.
If you must reduce the tire
pressure for whatever reason in
sand, make sure you re-inflate the
tires as soon as possible.
Avoid excessive speed because
vehicle momentum can work
against you and cause the vehicle
to become stuck to the point that
assistance may be required from
another vehicle. Remember, you
may be able to back out the way
you came if you proceed with
caution.
Mud
Be cautious of sudden changes in
vehicle speed or direction when
you are driving in mud. Even 4WD

and AWD vehicles can lose traction
in slick mud. As when you are
driving over sand, apply the
accelerator slowly and avoid
spinning your wheels. If the vehicle
does slide, steer in the direction of
the slide until you regain control of
the vehicle.
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 vehicle
components.
ªTread Lightlyº is an educational
program designed to increase
public awareness of land-use
regulations and responsibilities in
our nations wilderness areas. Ford
joins the U.S. Forest Service and
the Bureau of Land Management in
encouraging you to help preserve
our national forest and other
public and private lands by
ªtreading lightly.º

Water
Before driving through water,
determine the depth. Avoid water
higher than the bottom of the
wheel hubs. Proceed slowly to
avoid splashing, 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.
You can dry the brakes faster by
driving the vehicle slowly while
applying light pressure on the
brake pedal.
Deep snow
4WD and AWD vehicles are unique
in that they can be driven in deep
snow that would stop a
conventional two-wheel drive
vehicle. Shift to a low gear and
maintain steady pressure on the
accelerator. This will help prevent
spinning the wheels while
maintaining sufficient momentum
to keep from bogging down. Using
tire chains will also help.
Never drive with chains on the
front tires of 4WD or AWD vehicles
without also putting them on the
rear tires. This could cause the
rear to slide and swing around
during braking.
Driving on hills
Although natural obstacles may
make it necessary to travel
Driving off-road with 4WD or AWD
12

diagonally up or down a hill or
steep incline, you should always
try to drive straight up or straight
down.Avoid driving crosswise
or turning on steep slopes or
hills. A danger lies in losing
traction, slipping sideways and
possibly rolling over. Whenever
driving on a hill, determine
beforehand the route you will use.
Do not drive over the crest of a hill
without seeing what conditions are
on the other side. Do not drive in
reverse over a hill without the aid
of an observer.
When climbing a steep slope or
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.
If you do stall out, Do not try to
turnaround because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the
wheels to climb the hill. Too much
power will cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.

TIRES, REPLACEMENT
REQUIREMENTS
Your 4WD or AWD vehicle is
equipped with tires designed to
provide for safe ride and handling
capability.
Do not use a size and type of tire
and wheel other than that
originally provided by Ford
because it can affect the safety
and performance of your vehicle,
which could lead to loss of vehicle
control or rollover and serious
injury. Make sure all tires and
wheels on the vehicle are of the
same size, type, tread design,
brand and load-carrying capacity. If
you have questions regarding tire
replacement, see an authorized
Ford or Lincoln/Mercury dealer.
If you nevertheless decide to equip
your 4WD or AWD for off-road use
with tires larger than what Ford
recommends, you should not use
these tires for highway driving.
If you use any tire/wheel
combination not recommended by
Ford, it may adversely affect
vehicle handling and could cause
steering, suspension, axle or
transfer case failure.
Do not useºaftermarket lift kitsº or
other suspension modifications,
whether or not they are used with
larger tires and wheels.
These ªaftermarket lift kitsº could
adversely affect the vehicle's
handling characteristics, which
could lead to loss of vehicle

control or rollover and serious
injury.
Tires can be damaged during
off-road use. For your safety, tires
that are damaged should not be
used for highway driving because
they are more likely to blow out or
fail.
You should carefully observe the
recommended tire inflation
pressure found on the safety
compliance certification label
attached to the left front door lock
facing or door latch post pillar.
Failure to follow tire pressure
recommendations can adversely
affect the way your vehicle
handles. Do not exceed the Ford
recommended pressure even if it is
less than the maximum pressure
allowed for the tire.
Each day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to
check pressure of all tires, and
adjust if required. Check tire
pressure with a tire gauge every
few weeks (including spare). Safe
operation requires tires that are
neither underinflated nor
overloaded.
Periodically inspect the tire treads
and remove stones, nails, glass or
other objects that may be wedged
in the tread grooves. Check for
holes or cuts that may permit air
leakage from the tire and make
necessary repairs.
