(Continued)
4500/5500 Models
These vehicles do not come equipped with a
jack.
NOTE:
Jacking and tire changing on 4500/
5500 models should be performed by an autho -
rized dealer, or knowledgeable service
personnel with the appropriate heavy duty
equipment, like a tire service company.
Preparations For Jacking

1. Park the vehicle on a firm, level surface. Avoid ice or slippery areas.

2. Place the gear selector into PARK. On four-wheel drive vehicles, shift the transfer
case to the 4L position.
3. Turn on the Hazard Warning flashers.
4. Apply the parking brake. 5. Turn the ignition OFF.
6. Block both the front and rear of the wheel
diagonally opposite the jacking position. For
example, if the driver’s front wheel is being
changed, block the passenger’s rear wheel.

Wheel Blocked

NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.
Jacking Instructions 4500 And 5500 Series
WARNING!
Do not attempt to change a tire on the side of
the vehicle close to moving traffic. Pull far
enough off the road to avoid being hit when
operating the jack or changing the wheel.
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
Turn on the Hazard Warning flashers.
Apply the parking brake firmly and set the
transmission in PARK.
Block the wheel diagonally opposite the
wheel to be raised.
Never start or run the engine with the
vehicle on a jack.
Do not let anyone sit in the vehicle when it
is on a jack.
Do not get under the vehicle when it is on a
jack. If you need to get under a raised
vehicle, take it to a service center where it
can be raised on a lift.

Jack Warning Label
1. If equipped, remove the spare wheel, jack,
and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them coun -
terclockwise one turn while the wheel is still
on the ground.
3. When changing the front wheel, assemble the jack driver to the jack and connect the
jack driver to the extension tube. Place the
jack under the axle as close to the tire as
possible with the jack driver extending to
the front. Connect the extension tubes and
lug wrench.

Front Jacking Locations

When changing a rear wheel, assemble the
jack driver to the jack and connect the jack
driver to the extension tubes. Securely
place the jack under the sway bar bracket (unless both tires are flat on one side, then
place jack under shock bracket) facing for
-
ward in vehicle. Connect the extension
tubes and lug wrench.

Rear Jacking Location

Before raising the wheel off the ground,
make sure that the jack will not damage
surrounding truck parts and adjust the jack
position as required.
NOTE:
If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle until the wheel just clears the
surface.
Only use the jack in the positions indicated
and for lifting this vehicle during a tire
change.
If working on or near a roadway, be
extremely careful of motor traffic.
To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle.

IN CASE OF EMERGENCY317
5. Remove the lug nuts and pull the wheel off.
Install the spare wheel and lug nuts with the
cone shaped end of the nuts toward the
wheel on Single Rear-Wheel (SRW) models.
On Dual Rear-Wheel models (DRW) the lug
nuts are a two-piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk
of forcing the vehicle off the jack, do not
fully tighten the nuts until the vehicle has
been lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern. For the
proper lug nut torque specifications refer to
“Wheel And Tire Torque Specifications” in
“Technical Specifications.” If in doubt about
the correct tightness, have them checked
with a torque wrench by an authorized
dealer or at a service station. 7. Install wheel center cap (if equipped) and
remove wheel blocks. Do not install chrome
or aluminum wheel center caps on the
spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary
to use the jack driver in order to lower the
jack. Stow the replaced tire, jack, and tools
as previously described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.
Dual Rear Wheels
Slots in the wheels will assist in properly
orienting the inner and outer wheels. Align
these slots when assembling the wheels for
best access to the tire valve on the inner wheel.
The tires of both dual wheels must be
completely off the ground when tightening to
insure wheel centering and maximum wheel
clamping.
Dual wheel models require a special heavy-duty
lug nut tightening adapter (included with the
vehicle) to correctly tighten the lug nuts. Also,
when it is necessary to remove and install dual
rear wheels, use a proper vehicle lifting device.
NOTE:
When installing a spare tire (if equipped) as part
of a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference,
the larger tire should be installed in a front loca-
tion. The correct direction of rotation for dual
tire installations must also be observed.WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places
provided.

318IN CASE OF EMERGENCY
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque
wheel stud nuts to specifications at each lubri -
cation interval.
Refer to “Wheel And Tire Torque Specifications”
in “Technical Specifications” for further infor -
mation.
Wheel Nuts
All wheel nuts should be tightened occasionally
to eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels
becoming elongated. This is especially
important during the first few hundred miles/
kilometers of operation to allow the wheel nuts
to become properly set. All wheel nuts should
first be firmly seated against the wheel. The
wheel nuts should then be tightened to recom -
mended torque. Tighten the wheel nuts to final
torque in increments. Progress around the bolt
circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved. Refer to “Wheel And Tire Torque Specifications”
in “Technical Specifications” for further infor
-
mation.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builder’s Guide for infor -
mation on stowing your spare tire (if equipped).
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising
the vehicle off the ground. For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull
off the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.

Lug Wrench Insertion Location — Hub Cap

CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to
the center cap and/or the wheel if
screwdriver type tools are used. A pulling
motion, not a pry off motion, is recommended
to remove the caps.

2020_RAM_CHASSIS_CAB_OM_USA=GUID-6C67832B-7839-4CCF-BEFC-CDF988F949EA=1=en=.book Page 318

IN CASE OF EMERGENCY319
On 3500 models with Dual Rear-Wheels (DRW),
you must first remove the hub caps—use the
procedure noted for the single rear wheel. For
the wheel covers (wheel skins), insert the flat
end of the lug wrench between the outer edge
of the wheel cover and the wheel. Pry against
the wheel to remove the wheel cover. Repeat
this procedure around the wheel until the cover
pops off.

Lug Wrench Insertion Location — Wheel Cover
Replace the wheel covers using a rubber mallet
to ease the installation. Align the wheel cover
vent holes to the wheel vent holes. Tap on the
wheel cover as needed to firmly seat it evenly
around the wheel.
JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle, or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so please
follow the procedures in this section carefully. NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc
-
tions and precautions.
CAUTION!
Use a pulling motion to remove the hub
cap. Do not use a twisting motion when
removing the hub cap, damage to the hub
cap; finish may occur.
The rear hub caps on the dual rear wheel
has two pull off notches. Make sure that the
hook of the jack handle driver is located
squarely in the cap notch before attempting
to pull off.
WARNING!
Do not attempt jump starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.

322IN CASE OF EMERGENCY
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
GEAR SELECTOR OVERRIDE — 6–SPEED
TRANSMISSION
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position, you
can use the following procedure to temporarily
move the gear selector:

1. Turn the engine OFF.

2. Firmly apply the parking brake.
3. Tilt the steering wheel to the full up position.
4. Press and maintain firm pressure on the
brake pedal. 5. Insert a screwdriver or similar tool into the
access port (ringed circle) on the bottom of
the steering column, and push and hold the
override release lever up.

WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.

324IN CASE OF EMERGENCY
Follow these steps to activate the Manual Park
Release:

1. Firmly apply the parking brake.

2. Using a small screwdriver or similar tool,
remove the Manual Park Release access
cover, which is just above the parking brake
release handle, below and to the left of the
steering column.
3. Press and maintain firm pressure on the brake pedal.
4. Using the screwdriver or similar tool, push the Manual Park Release lever locking tab
(just below the middle of the lever) upwards.
5. While holding the locking tab in the disen -
gaged position, pull the tether strap to
rotate the lever rearward, until it locks in
place pointing towards the driver's seat.
Release the locking tab and verify that the
Manual Park Release lever is locked in the
released position. 6. The vehicle is now out of PARK and can be
towed. Release the parking brake only when
the vehicle is securely connected to a tow
vehicle.
To Reset The Manual Park Release:

1. Push the locking tab to the right, to unlock the lever.

2. Rotate the Manual Park Release lever forward to its original position, until the
locking tab snaps into place to secure the
lever.
3. Pull gently on the tether strap to confirm that the lever is locked in its stowed posi-
tion.
4. Re-install the access cover.FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand, or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left to
clear the area around the front wheels. Then
shift back and forth between DRIVE (D) and
REVERSE (R), while gently pressing the acceler -
ator. Use the least amount of accelerator pedal
pressure that will maintain the rocking motion,
without spinning the wheels or racing the
engine.

2020_RAM_CHASSIS_CAB_OM_USA=GUID-6C67832B-7839-4CCF-BEFC-CDF988F949EA=1=en=.book Page 324

IN CASE OF EMERGENCY325
NOTE:
For trucks equipped with an 8–speed trans -
mission, shifts between DRIVE and REVERSE
can only be achieved at wheel speeds of
5 mph (8 km/h) or less. Whenever the trans -
mission remains in NEUTRAL (N) for more
than two seconds, you must press the brake
pedal to engage DRIVE or REVERSE.
Push the “ESC OFF” switch, to place the Elec -
tronic Stability Control (ESC) system in
“Partial Off” mode, before rocking the
vehicle. Refer to “Electronic Brake Control
System” in “Safety” for further information.
Once the vehicle has been freed, push the
“ESC OFF” switch again to restore “ESC On”
mode.
WARNING!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause damage, or even failure, of the axle
and tires. A tire could explode and injure
someone. Do not spin your vehicle's wheels
faster than 30 mph (48 km/h) or for longer
than 30 seconds continuously without
stopping when you are stuck and do not let
anyone near a spinning wheel, no matter
what the speed.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating and
failure. Allow the engine to idle with the
transmission in NEUTRAL for at least one
minute after every five rocking-motion
cycles. This will minimize overheating and
reduce the risk of transmission failure
during prolonged efforts to free a stuck
vehicle.
When “rocking” a stuck vehicle by shifting
between DRIVE and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drivetrain damage may result.
Revving the engine or spinning the wheels
too fast may lead to transmission over -
heating and failure. It can also damage the
tires. Do not spin the wheels above 30 mph
(48 km/h) while in gear (no transmission
shifting occurring).
