OFF-ROAD DRIVING
WHAT IS OFF-ROAD DRIVING
Off-road driving is driving your vehicle on
unsurfaced roads or trails, made from dirt,
rocks, sand and mud.
OFF-ROAD DRIVING
PRECAUTIONS - RAPTOR
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
Before going off-road driving, consult with
all the appropriate government entities to
determine where you are legally allowed
to operate your vehicle and what permits
or registrations are required to do so.
Inspect your vehicle before and after any
off-road driving.
Familiarize yourself with the dimensions
of your vehicle including approach angles,
breakover angles, and ground clearance.
Also familiarize yourself with the features
of your vehicle. Some of these features
such as drive modes and cameras can
improve your off-road driving experience.
Secure loose objects inside your vehicle
and in the cargo area.
BASIC OFF-ROAD DRIVING
TECHNIQUES - RAPTOR
Grip the steering wheel with your thumbs
on the outside of the rim. This reduces the
risk of injury due to abrupt steering wheel
motions that occur when negotiating rough
terrain. If you are driving in a dusty area, be sure to
leave ample distance between your vehicle
and any other vehicles to allow for
adequate vision.
BASIC OFF-ROAD DRIVING
TECHNIQUES
Off-road Driving Hints
Before taking your vehicle off-roading, a
basic vehicle inspection should be done to
make sure that the vehicle is in top working
condition. It is always recommended that
at least two vehicles are used while
off-roading. The buddy system helps make
sure that help is close at hand should a
vehicle become stuck or damaged. It is also
wise to take supplies such as a first aid kit,
supply of water, tow strap, cell or satellite
phone with you any time an off-road
excursion is planned.
1. Grip the steering wheel with thumbs
on the outside of the rim. This will
reduce the risk of injury due to abrupt
steering wheel motions that occur
when negotiating rough terrain.
2. Throttle, brake and steering inputs should be made in a smooth and
controlled manner. Sudden inputs to
the controls can cause loss of traction
or upset the vehicle, especially while
on loose terrain or while crossing
obstacles such as rocks or logs.
3. Look ahead on your route noting upcoming obstacles, or any other
factors which may indicate a change
in available traction, and adjust the
vehicle speed and route accordingly.
4. When driving off-road, if the front or rear suspension is bottoming out
and/or excessive contact with the
skid-plates is encountered, reduce
vehicle speed to avoid potential
damage to the vehicle.
470
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Driving Hints

5. When with other vehicles, it is
recommended that communication is
used, and the lead vehicle notify other
vehicles of obstacles that could cause
potential vehicle damage.
6. Always keep available ground clearance in mind and pick a route that
minimizes the risk of catching the
underside of the vehicle on an obstacle.
7. When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from jerking and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
will also help with this.
8. 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 if you
plan to off-road.
Crossing Obstacles
• Review the path ahead before
attempting to cross any obstacle. It is
best if the obstacle is reviewed from
outside the vehicle so that there is a
good understanding of terrain condition
both in front of and behind the
obstacle.
• Approach obstacles slowly.
• 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 will help prevent damage
to the vehicle.
• Ditches and washouts should be
crossed at a 45° 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 hill descent
control. Use the throttle and brake
pedals to control your descent speed.
Note: Hill descent control is functional in
reverse and should be used in this situation.
DRIVING OFF-ROAD - RAPTOR
Driving In Snow and Ice WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Make sure you allow sufficient distance
between your vehicle and other vehicles
for stopping.
Driving In Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
