2018 Ram 4500 Chassis Cab wheel

4. By rotating the lug wrench clockwise,raise the vehicle until the wheel just
clears the surface.
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.
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 assem-
bly 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 Specifi-
cations” 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.
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.
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.
To Stow The Flat Or Spare —
If Equipped
Refer to Upfitters Body Builders Guide for
information 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.
CAUTION!
Use extreme caution when removing the
front and rear center caps. 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 recom-
mended to remove the caps.
For single rear wheel (SRW) models, use the
flat blade on the end of the lug wrench to pull
the hub cap off. Insert the blade end into the
pull off notch and carefully pull the hub cap
off with a back and forth motion.
163

On 3500 models with dual rear wheels
(DRW), you must first remove the hub caps.
The jack handle driver has a hook at one end
that will fit in the pull off notch of the rear
hub caps. Position the hook and pull straight
out on the ratchet firmly. The hub cap should
pop off. The wheel skins can now be re-
moved. For the front hub cap, use the flat
blade on the end of the lug wrench to pull the
caps off. The wheel skin can now be removed.
CAUTION!
• Use a pulling motion to remove the hubcap. 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.
You must use the flat end of the lug wrench to
pull off the wheel skins. Locate the hub cap
pull notches (2 notches on each cap). Insert the flat tip completely and using a back and
forth motion, loosen the wheel skin. Repeat
this procedure around the tire until the skin
pops off.
Replace the wheel skins first using a rubber
mallet. When replacing the hub caps, tilt the
cap retainer over the lug nut bolt circle and
strike the high side down with a rubber mal-
let. Be sure that the hub caps and wheel
skins are firmly seated 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.
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.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump Start
The battery in your vehicle is located in the
front of the engine compartment, behind the
left headlight assembly.
IN CASE OF EMERGENCY
164

• In city traffic — while stopped, place thetransmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.
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.
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
WARNING!
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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily 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.

6. Move the gear selector to the NEUTRALposition.
7. The vehicle may then be started in NEUTRAL.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand,
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Next, shift back and forth between DRIVE
and REVERSE (with automatic transmission)
or SECOND GEAR and REVERSE (with
manual transmission) while gently pressing
the accelerator. Use the least amount of ac-
celerator pedal pressure that will maintain
the rocking motion, without spinning the
wheels or racing the engine. NOTE:
Push the "ESC Off" switch, to place the Elec-
tronic Stability Control (ESC) system in "Par-
tial Off" mode, before rocking the vehicle.
Refer to “Electronic Brake Control System”
in “Safety” in the Owner’s Manual at
www.mopar.com/en-us/care/owners-manual.html
(U.S. Residents) or www.owners.mopar.ca
(Canadian Residents) 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 over-
heating 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 mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND GEAR 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
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

CAUTION!
• Do not use sling type equipment whentowing. Vehicle damage may occur.
• When securing the vehicle to a flat bed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with the rear wheels on the ground)
under the following conditions:
• The transmission must be in NEUTRAL.
• The towing speed must not exceed 30 mph (48 km/h).
• The towing distance must not exceed 15 miles (24 km). If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 15 miles (24 km),
tow with the rear wheels
OFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with the front wheels raised and
the rear wheels on a towing dolly, or (when
using a suitable steering wheel stabilizer to
hold the front wheels in the straight position)
with rear wheels raised and the front wheels
on the ground.CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe en-
gine and/or transmission damage. Damage
from improper towing is not covered under

Four-Wheel Drive Models
The manufacturer recommends towing with
all wheels OFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of vehicle raised and the opposite
end on a towing dolly. If flatbed equipment is not available, and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with
ALL
wheels on the ground), IFthe transfer case is
in NEUTRAL and the transmission is in PARK
(for automatic transmissions) or in gear (NOT
in NEUTRAL, for manual transmissions). Re-
fer to “Recreational Towing” in “Starting And
Operating” for further information and de-
tailed instructions.
CAUTION!
• Front or rear wheel lifts must not be used (if the remaining wheels are on the
ground). Internal damage to the trans-
mission or transfer case will occur if a
front or rear wheel lift is used when
towing.
