2020 Ram 3500 warning

STARTING AND OPERATING307
applied turn signal (if the left turn signal is
applied and the vehicle departs to the right), the
LaneSense system provides a haptic warning in
the form of torque applied to the steering wheel
to prompt the driver to remain within the lane
boundaries. The LaneSense system will also
provide a visual warning through the instrument
cluster display to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across that
lane marking (no turn signal applied), the
LaneSense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
NOTE:
When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provides
an audible and visual warning to the driver when the driver’s hands are not detected on the
steering wheel. The system will cancel if the
driver does not return their hands to the wheel.
TURNING LANESENSE ON OR OFF
The LaneSense button is located on
the switch panel below the Uconnect
display.
NOTE:
If your vehicle is equipped with a 12–inch Ucon -
nect Display screen, the LaneSense button is
located above the display.
To turn the LaneSense system on, push the
LaneSense button (LED turns off). A
“LaneSense On” message is shown in the
instrument cluster display.

308STARTING AND OPERATING

Left Lane Departure — Only Left Lane Detected

When the LaneSense system is on, the Lane -
Sense Telltale is solid white when only the
left lane marking has been detected and the
system is ready to provide visual warnings in
the instrument cluster display if an uninten -
tional lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the visual warning in the
instrument cluster display will show the left
lane line flashing yellow (on/off). The Lane -
Sense telltale changes from solid white to
flashing yellow.

Lane Crossed (Flashing Yellow Lane Line) With Yellow Telltale
NOTE:
The LaneSense system operates with similar
behavior for a right lane departure when only
the right lane marking has been detected.
Left Lane Departure — Both Lane Lines
Detected
When the LaneSense system is on and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs. The lane lines
turn from gray to white and the LaneSense
telltale is solid green.

Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

ENGINE RUNAWAY — DIESEL ENGINE
Diesel engine runaway is a rare condition
affecting diesel engines, where the engine
consumes its own lubrication oil and runs at
higher and higher RPM until it overspeeds to a
point where it destroys itself due to either
mechanical failure or engine seizure through
lack of lubrication.
REFUELING THE VEHICLE — GAS ENGINE
The fuel filler cap (gas cap) is located behind the
fuel filler door, on the left side of the vehicle.
Open the fuel door and remove the fuel filler cap
by turning it counter-clockwise.
Fuel Filler Cap

NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
NOTE:
When the fuel nozzle “clicks” or shuts off, the
fuel tank is full.
WARNING!
In case of engine runaway due to flammable
fumes from fuel spills or turbocharger oil
leaks being sucked into the engine, do the
following to help avoid personal injury and/or
vehicle damage:
1. Turn the ignition switch to the OFF position.
2. Using a CO2 or dry chemical type fire
extinguisher, direct the spray from the fire
extinguisher into the grille on the driver side
so that the spray enters the engine air intake.
The inlet for the engine air intake is located
behind the drivers side headlamp and
receives air through the grille.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the gas cap is
removed or the tank is being filled.
Never add fuel to the vehicle when the
engine is running.
A fire may result if gasoline is pumped into
a portable container that is inside of a
vehicle. You could be burned. Always place
gas containers on the ground while filling.
CAUTION!
Damage to the fuel system or emissions
control system could result from using an
improper fuel tank filler tube cap.
A poorly fitting fuel filler cap could let impu-
rities into the fuel system.
A poorly fitting fuel filler cap may cause the
“Malfunction Indicator Light (MIL)” to turn
on.
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling. When the
fuel nozzle “clicks” or shuts off, the fuel
tank is full.

320STARTING AND OPERATING
Tighten the gas cap until you hear a “clicking”
sound. This is an indication that the gas cap
is tightened properly. The MIL in the instru -
ment cluster may turn on if the gas cap is not
secured properly. Make sure that the gas cap
is tightened each time the vehicle is refueled.
LOOSE FUEL FILLER CAP MESSAGE
If the vehicle diagnostic system
determines that the fuel filler cap is
loose, improperly installed, or

There is no fuel filler cap. A flapper door inside
the filler pipe seals the system. 2. Insert the fuel nozzle fully into the filler pipe
– the nozzle opens and holds the flapper
door while refueling.
3. Fill the vehicle with fuel – when the fuel nozzle “clicks” or shuts off the fuel tank is
full.
4. Remove the fuel nozzle and close the fuel door.
Emergency Fuel Can Refueling
NOTE:
In the event that you run the vehicle out of fuel,
once refueled, place the ignition in the ON posi -
tion for 30 seconds, then turn the ignition OFF
and wait 30 seconds. Repeat this procedure
three times, prior to cranking the engine.
Most fuel cans will not open the flapper door.
A funnel is provided to open the flapper door to
allow emergency refueling with a fuel can.

1. Retrieve fuel funnel from the jack kit located under the front passenger seat.

2. Insert funnel into same filler pipe opening as the fuel nozzle.
WARNING!
Always place container on the ground
before filling.
Keep the pump nozzle in contact with the
container when you are filling it.
Use only approved containers for flam -
mable liquid.
Do not leave container unattended while
filling.
A static electric charge could cause a spark
and fire hazard.

DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective
Catalytic Reduction (SCR) system to meet the
very stringent diesel emissions standards
required by the Environmental Protection
Agency.
The purpose of the SCR system is to reduce
levels of NOx (oxides of nitrogen emitted from
engines) that are harmful to our health and the
environment to a near-zero level. A small
quantity of Diesel Exhaust Fluid (DEF) is injected into the exhaust upstream of a catalyst
where, when vaporized, it converts
smog-forming nitrogen oxides (NOx) into
harmless nitrogen (N2) and water vapor (H2O),
two natural components of the air we breathe.
You can operate with the comfort that your
vehicle is contributing to a cleaner, healthier
world environment for this and generations to
come.
System Overview
This vehicle is equipped with a Diesel Exhaust
Fluid (DEF) injection system and a Selective
Catalytic Reduction (SCR) catalyst to meet the
emission requirements.
The DEF injection system consists of the
following components:
DEF tank
DEF pump
DEF injector
Electronically-heated DEF lines
DEF control module
NOx sensors

2 — Emergency Diesel Fuel Fill Funnel
3 — Diesel Fuel Fill Location
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open
or the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the
“Malfunction Indicator Light” to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a
vehicle. You could be burned. Always place
fuel containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not
“top off” the fuel tank after filling.
