2023 RAM CHASSIS CAB warning light

TECHNICAL SPECIFICATIONS413
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
recommended 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.
FUEL REQUIREMENTS— GASOLINE ENGINE
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use of
gasoline with a lower than recommended octane
number can cause engine failure and may void or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
6.4L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
satisfactory fuel economy and
performance when using high quality
unleaded gasoline having a posted octane number
of 87 as specified by the (R+M)/2 method.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner-burning gasoline referred to as
“reformulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically blended
to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will
provide improved performance and durability of
engine and fuel system components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper
octane rating, gasolines that contain detergents,
corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, reduce
emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to
further aide in minimizing engine and
fuel system deposits. When available,
the usage of TOP TIER Detergent Gasoline is
recommended. Visit
www.toptiergas.com for a list
of TOP TIER Detergent Gasoline retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials
intended for gum and varnish removal may contain
active solvents or similar ingredients. These can
harm fuel system gasket and diaphragm materials.WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.

FUEL SYSTEM CAUTIONSNOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
FUEL REQUIREMENTS – DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier in your vehicle. Federal law requires that
you must fuel this vehicle with Ultra Low Sulfur
Highway Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Diesel fuel
(500 ppm Sulfur maximum) to avoid damage to the
emissions control system.
For most year-round service, Number 2 diesel fuel
meeting ASTM (formerly known as the American
Society for Testing and Materials) specification
D-975 Grade S15 will provide good performance. If
the vehicle is exposed to extreme cold (below 20°F
or -7°C), or is required to operate at
colder-than-normal conditions for prolonged
periods, use climatized Number 2 diesel fuel or
dilute the Number 2 diesel fuel with 50% Number
1 diesel fuel. This will provide better protection
from fuel gelling or wax-plugging of the fuel filters. Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the
accumulated water from the fuel/water separator
using the fuel/water separator drain provided on
both fuel filters. If you buy good quality fuel and
follow the cold weather advice above, fuel
conditioners should not be required in your vehicle.
If available in your area, a high cetane “premium”
diesel fuel may offer improved cold-starting and
warm-up performance.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can impair
engine performance and damage the emis
-
sions control system.
An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your engine
may be out of tune or malfunctioning and may
require immediate service. Contact an autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain
conditions and hazardous or explosive when
mixed with diesel fuel.
CAUTION!
If the Water in Fuel Indicator Light remains on,
DO NOT START engine before you drain the water
from the fuel filter(s) to avoid engine damage
