light Ram 3500 2016 Owner's Manual

CAUTION!
Reduced tire pressures may cause tire unseating and
total loss of air pressure. To reduce the risk of tire
unseating, while at a reduced tire pressure, reduce
your speed and avoid sharp turns or abrupt maneu-
vers.
Crossing Obstacles (Rocks And Other High
Points)
While driving off road, you will encounter many types of
terrain. These varying types of terrain bring different
types of obstacles. Before proceeding review the path
ahead to determine the correct approach and your ability
to safely recover the vehicle if something goes wrong.
Keeping a firm grip on the steering wheel, bring the
vehicle to a complete stop and then inch the vehicle
forward until it makes contact with the object. Apply thethrottle lightly while holding a light brake pressure and
ease the vehicle up and over the object.
WARNING!
Crossing obstacles can cause abrupt steering system
loading which could cause you to loose control of
your vehicle.
Using A Spotter
There are many times where it is hard to see the obstacle
or determine the correct path. Determining the correct
path can be extremely difficult when you are confronting
many obstacles. In these cases have someone guide you
over, through, or around the obstacle. Have the person
stand a safe distance in front of you where they can see
the obstacle, watch your tires and undercarriage, and
guide you through.

Crossing Logs
To cross a log, approach it at a slight angle (approxi-
mately 10 to 15 degrees). This allows one front tire to be
on top of the log while the other just starts to climb the
log. While climbing the log, modulate your brake and
accelerator to avoid spinning the log out from under your
tires. Then ease the vehicle off the log using your brakes.
CAUTION!
Do not attempt to cross a log with a greater diameter
than the running ground clearance or the vehicle will
become high centered.
Getting High Centered
If you get hung up or high centered on an object, get out
of the vehicle and try to determine what the vehicle is
hung up on, where it is contacting the underbody andwhat is the best direction to recover the vehicle. Depend-
ing on what you are in contact with, jack the vehicle up
and place a few rocks under the tires so the weight is off
of the high point when you let the vehicle down. You can
also try rocking the vehicle or winching the vehicle off
the object.
CAUTION!
Winching or rocking the vehicle off hard objects
increases the risk of underbody damage.
Hill Climbing
Hill climbing requires good judgment and a good under-
standing of your abilities and your vehicle’s limitations.
Hills can cause serious problems. Some are just too steep
to climb and should not be attempted. You should always
5
STARTING AND OPERATING 577

feel confident with the vehicle and your abilities. You
should always climb hills straight up and down. Never
attempt to climb a hill on an angle.
•Before Climbing A Steep Hill – As you approach a
hill consider its grade or steepness. Determine if it is
too steep. Look to see what the traction is on the hill
side trail. Is the trail straight up and down? What is on
top and the other side? Are there ruts, rocks, branches
or other obstacles on the path? Can you safely recover
the vehicle if something goes wrong? If everything
looks good and you feel confident, then change trans-
mission into a lower gear, shift the transfer case into
4LO (Low) and proceed with caution. You should use
first gear and 4LO (Low Range) for very steep hills.
• Driving Up Hill – Once you have determined your
ability to proceed and have shifted into the appropri-
ate gear, line your vehicle up for the straightest pos-
sible run. Accelerate with an easy constant throttle and apply more power as you start up the hill. Do not race
forward into a steep grade, the abrupt change of grade
could cause you to lose control. If the front end begins
to bounce, ease off the throttle slightly to bring all four
tires back on the ground. As you approach the crest of
the hill ease off the throttle and slowly proceed over
the top. If the wheels start to slip as you approach the
crest of a hill, ease off the accelerator and maintain
headway by turning the steering wheel no more than
a ¼ turn quickly back and forth. This will provide a
fresh
bite into the surface and will usually provide
enough traction to complete the climb. If you do not
make it to the top, place the vehicle in REVERSE and
back straight down the grade using engine resistance
along with the vehicle brakes.
578 STARTING AND OPERATING

WARNING!
Never attempt to climb a hill at an angle or turn
around on a steep grade. Driving across an incline
increases the risk of a roll over, which may result in
severe injury or death.
• Driving Down Hill – Before driving down a steep hill
you need to determine if it is too steep for a safe
descent. What is the surface traction? Is the grade too
steep to maintain a slow controlled descent? Are there
obstacles? Is it a straight descent? Is there plenty of
distance at the base of the hill to regain control if the
vehicle descends too fast? If you feel confident in your
ability to proceed then make sure you are in 4LO (Low
Range) with the transmission in first gear (manually
select first gear on automatic transmissions) and pro-
ceed with caution. Allow engine braking to control the descent and apply your brakes if necessary, but do not
allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.
• Driving Across An Incline – If at all possible avoid
driving across an incline. If it is necessary, know your
vehicle’s abilities. Driving across an incline places
more weight on the down hill wheels, which increases
the possibilities of a down hill slide or rollover. Make
sure the surface has good traction with firm and stable
soils. If possible transverse the incline at an angle
heading slightly up or down.
5
STARTING AND OPERATING 579

WARNING!
Driving across an incline increases the risk of a
rollover, which may result in severe injury.
• If You Stall Or Begin To Lose Headway – If you stall
or begin to lose headway while climbing a steep hill,
allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift into
REVERSE. Back slowly down the hill allowing the
compression braking of the engine and transmission to
help regulate your speed. If the brakes are required to
control vehicle speed, apply them lightly and avoid
locking or skidding the tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle, which may result in
severe injury. Always back carefully straight down a
hill in REVERSE. Never back down a hill in NEU-
TRAL using only the vehicle brakes. Never drive
diagonally across a hill, always drive straight up or
down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only
be attempted when necessary, in a safe responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly and
580 STARTING AND OPERATING

avoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls do not
attempt to restart it. Determine if it has ingested water
first. The key to any crossing is low and slow. You want
to use first gear in 4L (Low Range) and proceed very
slowly with a constant slow speed (3-5 mph [5–8 km/h]
maximum) and light throttle. Keep the vehicle moving;
do not try to accelerate through the crossing. After
crossing any water higher than the bottom of the axle
differentials, you should inspect all of the vehicle fluids
for signs of water ingestion.CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other
vehicle components and your brakes will be less
effective once wet and/or muddy.
• Before You Cross Any Type Of Water – As you
approach any type of water you need to determine if
you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a
stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe
5

downstream out of control if the water is deep enough
to push on the large surface area of the vehicle’s body.
Before you proceed determine the speed of the current,
the water’s depth, approach angle, bottom condition
and if there are any obstacles, then cross at an angle
heading slightly upstream using the low and slow
technique.
WARNING!
Never drive through fast moving deep water. It can
push your vehicle downstream, sweeping it out of
control. This could put you and your passengers at
risk of injury or drowning.
Airing Down For Off-Road Driving
Running lower tire pressure off-road can improve your
ride comfort and vehicle traction. Reducing the tire air
pressure allows the tire to bulge slightly, improving its
surface area for better flotation and ability to mold or
form to the ground contour. Different terrain, tires, and
vehicles require different tire pressure. Hard surfaces like
rock and heavier vehicles require higher pressures than
softer surfaces such as sand and lighter vehicles. You will
need to experiment to determine what is right for your
situation. It is easier and faster to let air out than it is to
replace it so, start high and lower it as required. Remem-
ber you must return the tires to normal air pressure
before driving on road or at highway conditions. Be sure
you have a way to return the tires to their normal on road
air pressure.
5
STARTING AND OPERATING 583

CAUTION!
Reduced tire pressure increases the risk of tire dam-
age and may cause tire unseating with total loss of air
pressure. To reduce the risk of tire unseating, while at
a reduced tire pressure, drive at slower speeds and
avoid sharp turns or abrupt maneuvers.
Vehicle Recovery
If you drive off-road, you may encounter a situation
where you will need to recover your vehicle. Vehicle
recovery should always be given consideration before
attempting a questionable obstacle. You should never go
off-road driving without the ability to recover your
vehicle from a situation. Having another vehicle with
you usually works best for most situations. The first
thing to do is assess the situation. Why are you stuck?
Are you hung up on something? Would it be easier to go
forward or to go backward? Can you still move thevehicle? Is there an anchor point to winch to? Are you
alone or do you have another vehicle to help? Is there
high risk of vehicle damage during the recovery process?
Answering these questions will help you determine the
best method of recovery. If you can still move the vehicle
slightly and the only issue is slick ground, then rock
cycling your vehicle would be the first choice. If you have
ample room, an additional vehicle and there is low risk of
vehicle impingement on the surroundings, then using a
tow strap to the vehicle tow hooks would be fast and
easy. If the vehicle is severely hung up or in a situation
where great care needs to be taken during the recovery,
then nothing can do the job better than a winch. If you are
severely hung up on something you should jack the
vehicle up and stack something under the wheels to
allow the vehicle to roll off the object without causing
further damage. This should be tried before attempting
any recovery method.
584 STARTING AND OPERATING

a safe recovery. First connect the tow strap to the
correct attachment points on both vehicles. There
should be a least 20 to 30 feet (6 to 9 meters) between
the vehicles to allow for a safe recovery. If necessary
join two tow straps together usinga1½inch hard
wood dowel. This will keep the straps from becoming
knotted and is safer than using a clevis pin if the strap
breaks. Next have the tow vehicle backup, leaving two
to three feet worth of slack in the strap. Then the tow
vehicle, using light throttle, should accelerate tighten-
ing the strap providing the pulling force needed to free
the vehicle. The vehicle being recovered should assist
in the recovery, at the time of the snap, by slowly
spinning the tires in the same direction as the pulling
vehicle. After the vehicle becomes free, the driver of
the previously stuck vehicle should signal they are free
and should hit their brakes stopping both vehicles. The
driver of the pulling vehicle should let off the throttle
without using the brakes, once signaled by the otherdriver. This sequence is important to avoid having the
recovered vehicle hit the pulling vehicle.
WARNING!
Never use tow straps with end hooks or link two
straps with a clevis pin. These heavy metal objects
could become projectiles if a strap breaks, which
could cause severe injury. Never leave more than 2 to
3 feet (.6 to 1 meter) of slack in the strap. More slack
than this greatly increases the risk of injury and
vehicle damage. Always keep everyone at least 30
feet (9 meters) away from a strapping or winching
situation.
• Winching (Refer To “Winch Operation” For Addi-
tional Information) – Winching is most commonly
used in the following situations: there is no support
vehicle available, a high controlled force is required to
586 STARTING AND OPERATING

recover the vehicle, there is a high risk of environmen-
tal or vehicle damage, or where nothing else seems to
work. A winch can deliver a high pulling force with a
great deal of control. It allows you to walk the vehicle
out of the situation in a slow controlled manner. This
control works well for avoiding further vehicle dam-
age. Once you decide it is time to use the winch look
for a good anchor point. It needs to be strong enough
to hold more than the vehicle’s weight and provide a
direction of pull as straight as possible. Use block and
tackle if necessary to improve the angle of pull or
increase the winch’s pulling force. If the anchor point
is a tree use a strap around its base and hook the cable
to the strap. If it is another vehicle, then place that
vehicle in PARK and block the front tires. If you cannot
find an anchor point within reach try using your spare
tire by burying it. Once you have determined an
anchor point hook up the cable, ensuring there are a
least five wraps of cable left on the drum, and place afloor mat or something else over the strung out cable.
Placing something over the strung out cable helps
keep the cable on the ground if it breaks. Next, place
the vehicle in first gear and apply a very light throttle
as you power the winch in. Be careful not to allow
slack in the cable as you recover the vehicle. Do not try
to guide the cable into the drum. If it starts to bunch up
on one end, let it. You can re-spool the cable after-
wards. Never use a winch cable as a tow strap and
always stand back while winching.
WARNING!
Winch cables are under high tension when in use and
can become a projectile if they fail. Never stand over
or straddle the winch cable. Never jerk or overload
the winch cable. Never stand in front of the vehicle
while winching. Failure to follow these instructions
can result in serious or fatal injury.
