2018 Ram 4500 Chassis Cab warning light

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

SCHEDULED SERVICING — GASOLINE
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures, and E85 fuel
usage will influence when the “Oil Change
Required” message is displayed. Severe Op-
erating Conditions can cause the change oil
message to illuminate as early as
3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can bereset by referring to the steps described under
“Warning And Indicator Lights” or “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” in your Owner’s
Manual at
www.mopar.com/en-us/care/
owner-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for further information.
Gasoline Engines:
Under no circumstances should oil change
intervals exceed 8,000 miles (13,000 km),
twelve months or 350 hours of engine run
time, whichever comes first. The 350 hours
of engine run or idle time is generally only a
concern for fleet customers.
Severe Duty:
Change Engine Oil at 4,000 miles
(6,500 km) or 350 hours of engine run time
if the vehicle is operated in a dusty and off
road environment or is operated predomi-
nately at idle or very low engine RPM’s. This
type of vehicle use is considered Severe Duty. Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look
for unusual wear or damage
• Check the fluid levels of the coolant reser- voir, brake master cylinder, power steering
and automatic transmission, and fill as
needed
• Check function of all interior and exterior lights

Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:• Driving style.
• Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
See the Tire Sizing Chart example found in
the “Tire Safety Information” section of this
manual for more information relating to the
Load Index and Speed Symbol of a tire.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
