fuel Ram 1500 2020 Owner's Guide

Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts and
cracks. Inspect sidewalls for cuts, cracks, and bulges. Check
the wheel bolts for tightness. Check the tires (including
spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline fumes
are detected or if fuel, or brake fluid leaks are suspected, the
cause should be located and corrected immediately.

STARTING AND OPERATING 295
(Continued)
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in
4WD LOW.
The MESSAGE “AutoPark Disabled ” will be displayed in
the instrument cluster.
Additional customer warnings will be given when all of
these conditions are met:
• Vehicle is not in PARK
• Driver’s Door is ajar
• Vehicle is in 4WD LOW range
The MESSAGE “ AutoPark Not Engaged ” will be displayed
in the instrument cluster. A warning chime will continue
until you shift the vehicle into PARK or the Driver’s Door is
closed.
ALWAYS DO A VISUAL CHECK
that your vehicle is in
PARK by looking for the "P" in the Instrument Cluster
Display and near the shifter. As an added precaution, always
apply the parking brake when exiting the vehicle. If Engine Fails To Start
If the engine fails to start after you have followed the
“Normal Starting” procedure, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while the engine is cranking. This should clear any excess
fuel in case the engine is flooded.
The starter motor will engage automatically, run for 10
seconds, and then disengage. Once this occurs, release the
accelerator pedal and the brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.
WARNING!
• Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the
vehicle. This could result in flash fire causing serious
personal injury.
• Do not attempt to push or tow your vehicle to get it started. Vehicles equipped with an automatic transmis -
sion cannot be started this way. Unburned fuel could
enter the catalytic converter and once the engine has
started, ignite and damage the converter and vehicle.

STARTING AND OPERATING 307

The following indicators should be used to ensure that you have
properly engaged the transmission into the PARK position:

• Look at the transmission gear position display and verifythat it indicates the PARK position (P), and is not blinking.
• With brake pedal released, verify that the gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete stop.
NEUTRAL (N)

Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake and
shift the transmission into PARK if you must exit the vehicle.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.
CAUTION!
• DO NOT race the engine when shifting from PARK or NEUTRAL into another gear range, as this can damage
the drivetrain.
• Before moving the transmission gear selector out of PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.
WARNING!
Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!
Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “In Case Of Emergency” for further
information.

312 STARTING AND OPERATING
NEUTRAL (N)
Neutral — This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat towing
behind another vehicle. Refer to “Recreational Towing” in
this section for further information.This electronically shifted transfer case is designed to be
driven in the two–wheel drive position (2WD) for normal
street and highway conditions on dry hard surfaced roads).
Driving the vehicle in 2WD will have greater fuel economy
benefits as the front axle is not engaged in 2WD.
When additional traction is required, the transfer case 4WD
HIGH and 4WD LOW positions can be used to maximize
torque to the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is accomplished by
pushing the desired position on the 4WD control switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.
The 4WD HIGH and 4WD LOW positions are designed for
loose, slippery road surfaces only. Driving in the 4WD HIGH
and 4WD LOW positions on dry, hard surfaced roads may
cause increased tire wear and damage to the driveline
components.
NOTE:
The transfer case NEUTRAL button is located in the center of
the 4WD Control Switch and is pushed by using a ballpoint
pen or similar object. The transfer case NEUTRAL position is
to be used for recreational towing only. Refer to “Recre
-
ational Towing” in “Starting And Operating” for further
information.
WARNING!
• You or others could be injured or killed if you leave the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive shaft
from the powertrain, and will allow the vehicle to roll,
even if the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
• The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.

316 STARTING AND OPERATING
This electronically shifted transfer case is designed to be
driven in the two–wheel drive position (2WD) or four-wheel
drive auto position (4WD AUTO) for normal street and
highway conditions on dry, hard surfaced roads. Driving the
vehicle in 2WD will have greater fuel economy benefits as
the front axle is not engaged in 2WD.For variable driving conditions, the 4WD AUTO mode can
be used. In this mode, the front axle is engaged, but the
vehicle's power is sent to the rear wheels. Four-wheel drive
will be automatically engaged when the vehicle senses a loss
of traction. Because the front axle is engaged, this mode will
result in lower fuel economy than the 2WD mode.
When additional traction is required, the transfer case 4WD
HIGH and 4WD LOW positions can be used to maximize
torque to the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is accomplished
pushing the desired position on the 4WD Control Switch.
Refer to “Shifting Procedure” in this section for specific
shifting instructions.

The 4WD HIGH and 4WD LOW positions are designed for
loose, slippery road surfaces only. Driving in the 4WD HIGH
and 4WD LOW positions on dry hard surfaced roads may cause
increased tire wear and damage to the driveline components.
NOTE:
The transfer case NEUTRAL button is located in the center of the
4WD Control Switch and is pushed by using a ballpoint pen or
similar object. The transfer case NEUTRAL position is to be used
for recreational towing only. Refer to “Recreational Towing” in
“Starting And Operating” for further information.

WARNING!
• You or others could be injured or killed if you leave the vehicle unattended with the transfer case in the
NEUTRAL (N) position without first fully engaging
the parking brake. The transfer case NEUTRAL (N)
position disengages both the front and rear drive shaft
from the powertrain, and will allow the vehicle to roll,
even if the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.
• The transmission may not engage PARK if the vehicle is moving. Always bring the vehicle to a complete stop
before shifting to PARK, and verify that the transmis -
sion gear position indicator solidly indicates PARK (P)
without blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly indicated,
before exiting the vehicle.

POWER STEERING
Electric Power Steering
The electric power steering system will give you effective
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and proper feel while driving. If the
electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
If the Steering icon is flashing, it indicates that the vehicle
needs to be taken to the dealer for service. It is likely the
vehicle has lost power steering assistance.
If the Steering icon is displayed and the “POWER STEERING
SYSTEM OVER TEMP” message is displayed on the instru-
ment cluster screen, they indicate that extreme steering
maneuvers may have occurred which caused an over
temperature condition in the power steering system. Once
driving conditions are safe, pull over and let the vehicle idle
for a few moments until the icon and message turn off. Refer
to “Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed the instru-ment cluster screen, they indicate the vehicle needs to be
taken to the dealer for service. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instrument Panel” for
further information.
NOTE:
• Even if the power steering assistance is no longer opera
-
tional, it is still possible to steer the vehicle. Under these
conditions there will be a substantial increase in steering
effort, especially at low speeds and during parking
maneuvers.
• If the condition persists, see your authorized dealer for service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES ONLY —
IF EQUIPPED
This feature offers improved fuel economy by shutting off
four of the engine's eight cylinders during light load and
cruise conditions. The system is automatic with no driver
inputs or additional driving skills required.
NOTE:
This system may take some time to return to full function -
ality after a battery disconnect.

334 STARTING AND OPERATING
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to save fuel and reduce
emissions. The system will stop the engine automatically
during a vehicle stop if the required conditions are met.
Releasing the brake pedal or shifting out of DRIVE will auto-
matically restart the engine.
Vehicles equipped with eTorque contain a heavy duty motor
generator and an additional hybrid electric battery to store
energy from vehicle deceleration for use on engine startup
after a stop as well as providing launch torque assist.
Automatic Mode
The Stop/Start feature is enabled after every normal
customer engine start. It will remain in STOP/START NOT
READY until you drive forward with a vehicle speed greater
than 2 mph (3 km/h). At that time, the system will go into
STOP/START READY and if all other conditions are met,
can go into an STOP/START AUTO STOP ACTIVE
“Autostop” mode.
To Activate The Autostop Mode, The Following Must
Occur:
1. The system must be in STOP/START READY state. A STOP/START READY message will be displayed in the instrument cluster within the Stop/Start section. Refer to
“Instrument Cluster Display” in “Getting To know Your
Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in DRIVE and the brake pedal depressed.
The engine will shut down, the tachometer will move to the
zero position and the stop/start telltale will illuminate indi -
cating you are in an Autostop. While in an Autostop, the
Climate Controls system may automatically adjust airflow to
maintain cabin comfort. Customer settings will be main -
tained upon return to an engine running condition.
Possible Reasons The Engine Does Not Autostop
Prior to engine shut down, the system will check many safety
and comfort conditions to see if they are fulfilled. In
following situations, the engine will not Autostop:
• Driver’s seat belt is not buckled
• Driver’s door is not closed
• The vehicle is on a steep grade
• Cabin heating or cooling is in process and an acceptable cabin temperature has not been achieved
