When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from lurching and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
also assists with this.
Use and equip supplemental safety
equipment.
Please consult your local off-road
group for other helpful tips.
Off-roading requires a high degree of
concentration. Even if your local law
does not prohibit alcohol use while
driving off-road, Ford strongly
recommends against drinking alcohol
if you plan to off-road.
Crossing Obstacles
Review the path ahead before
attempting to cross any obstacles. It is
best if the obstacles are reviewed from
outside the vehicle so that there is a
good understanding of the terrains
condition both in front of and behind
the obstacles.
Approach obstacles slowly and slowly
creep the vehicle over.
If a large obstacle such as a rock
cannot be avoided, choose a path that
places the rock directly under the tire
rather than the undercarriage of the
vehicle. This helps prevent damage to
the vehicle.
Ditches and washouts should be
crossed at a 45 degree angle, allowing
each wheel to independently cross the
obstacle.
Hill Climbing
WARNING: Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
Always attempt to climb a steep hill
along the fall line of the slope and not
diagonally.
If the vehicle is unable to make it up
the hill, DO NOT attempt to turn back
down the slope. Place the vehicle in
low range and slowly back down in
reverse.
When descending a steep slope, select
low gear and engage trail control. Use
the throttle and brake pedals to control
your descent speed as described earlier
in this section using trail control. Note
that trail control is functional in reverse
and should be used in this situation.
After Off-Road Driving
It is important to complete a full vehicle
inspection after off-road driving. Some
items to check include:
Make sure that tires are inflated to
proper tire pressure as indicated on the
tire placard.
Check the wheels and undercarriage
for built up mud or debris which can
cause vehicle vibration.
Make sure that the grille and radiator
are clear of any obstructions that may
affect cooling.
Make sure that the brakes are in proper
working order and free of any mud,
stones and debris, which can become
trapped around the brake rotor,
backing plate and caliper.
Check that the air filter is clean and dry.
Inspect for torn or punctured boots on
ball joints, half shafts, steering gears.
