2018 Ram 2500 instrument cluster

Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitoring
Telltale Light” will flash on and off for 75 seconds and then
remain on solid. The system fault will also sound a chime.
In addition, the instrument cluster will display aSERVICE
TPM SYSTEM message for a minimum of five seconds and
then display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and the SERVICE TPM SYSTEMmessage will no longer display, and a pressure value will
display in place of the dashes. A system fault can occur due
to any of the following:
•
Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
A system fault may occur due to an incorrect TPM sensor
location condition. When a system fault occurs due to an
incorrect TPM sensor location, the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also sound a
chime. In addition, the instrument cluster will display a
“Tire Pressure Temporarily Unavailable” message in place
of the tire pressure display screen. If the ignition switch is
cycled, this sequence will repeat, providing the system
fault still exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will no longer

flash and the tire pressure display screen will be displayed
showing the tire pressure values the correct locations.
Vehicles With Non Matching Full Size Spare Or Compact
Spare
•The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will
not monitor the pressure in the non matching full size
spare or compact spare tire.
• If you install the non matching full size spare or compact
spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
switch cycle, the TPM Telltale Light and a “LOW TIRE”
message will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a pressure value in a different color.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a SERVICE
TPM SYSTEM message for a minimum of five seconds
and then display dashes (- -) in place of the pressure
value. •
For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and the instrument
cluster will display a SERVICE TPM SYSTEM message
for a minimum of five seconds and then display dashes
(- -) in place of the pressure value.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale Light will
turn OFF and the graphic in the instrument cluster will
display a new pressure value instead of dashes (- -), as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) in order for the TPMS to
receive this information.
Tire Pressure Information System (TPIS) 3500 Series
Trucks
Your vehicle may be equipped with a Tire Pressure Infor-
mation System (TPIS).
The Tire Pressure Information System (TPIS) uses wireless
technology with wheel rim mounted electronic sensors to

transmit tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
The TPIS consists of the following components:
• Receiver module
• Four TPM sensors (Single Rear Wheel (SRW) applica-
tions)
• Six TPM sensors (Dual Rear Wheel (DRW) applications)
• Pressure display in the instrument cluster
The TPIS system will display all four (Single Rear Wheel
(SRW) applications) or six (Dual Rear Wheel (DRW) appli-
cations) tire pressure values in the instrument cluster
display.
If a system fault is detected, the instrument cluster will
display a SERVICE TPM SYSTEM message for a mini-
mum of five seconds and then display dashes (- -) in place
of the pressure value to indicate which sensor is not being
received. If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the
SERVICE TPM SYSTEM message will
no longer be displayed, and a pressure value will display
in place of the dashes. A system fault can occur due to any
of the following:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.

AutoPark — Rotary Shifter and 8-Speed Trans Only
AutoPark is a supplemental feature to assist in placing the
vehicle in PARK should the situations on the following
pages occur. It is a back up system and should not be relied
upon as the primary method by which the driver shifts the
vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
290 STARTING AND OPERATING

WARNING!
•Driver inattention could lead to failure to place the
vehicle in PARK. ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK by verifying that a solid
(not blinking) “P” is indicated in the Instrument
Cluster Display and near the gear selector. If the P
indicator is blinking, your vehicle is not in PARK. As
an added precaution, always apply the parking brake
when exiting the vehicle.
• AutoPark is a supplemental feature. It is not de-
signed to replace the need to shift your vehicle into
PARK. It is a back up system and should not be
relied upon as the primary method by which the
driver shifts the vehicle into PARK.
If the vehicle is not in PARK and the driver turns off the
engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with a rotary shifter and an 8-speed
transmission
• Vehicle is not in PARK •
Vehicle Speed is 1.2 MPH (1.9 km/h) or less
• Ignition switched from RUN to ACC
NOTE: For Keyless Go equipped vehicles, The engine will
turn off and the ignition switch will change to ACC mode.
After 30 minutes the ignition switches to OFF automati-
cally, unless the driver turns the ignition switch OFF.
If the vehicle is not in PARK and the driver exits the
vehicle with the engine running, the vehicle may Au-
toPark.
AutoPark will engage when all of these conditions are met:
• Vehicle is equipped with a rotary shifter and an 8-speed
transmission
• Vehicle is not in PARK
• Vehicle speed is 1.2 MPH (1.9 km/h) or less
• Driver ’s seat belt is unbuckled
• Driver ’s door is ajar
• Brake Pedal is not depressed
The MESSAGE “ AutoPark Engaged Shift to P then Shift
to Gear” will display in the instrument cluster.

STARTING AND OPERATING 291

NOTE:In some cases the ParkSense graphic will be
displayed in the instrument cluster, causing the “ Au-
toPark Engaged Shift to P then Shift to Gear” to not be
seen. In these cases, the shifter must be returned to “P” to
select desired gear.
If the driver shifts into PARK while moving, the vehicle
may AutoPark.
AutoPark will engage ONLYwhen vehicle speed is
1.2 MPH (1.9 km/h) or less.
The MESSAGE “ Vehicle Speed is Too High to Shift to
P”will be displayed in the instrument cluster if vehicle
speed is above 1.2 MPH (1.9 km/h).
WARNING!
If vehicle speed is above 1.2 MPH (1.9 km/h), the
transmission will default to NEUTRAL until the ve-
hicle speed drops below 1.2 MPH (1.9 km). A vehicle
left in the NEUTRAL position can roll. As an added
precaution, always apply the parking brake when
exiting the vehicle. 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 dis-
played 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 Pin the Instrument Cluster
Display and near the shifter. As an added precaution,
always apply the parking brake when exiting the vehicle.
292 STARTING AND OPERATING

When the parking brake is applied with the ignition switch
ON, the “Brake Warning Light” in the instrument cluster
will illuminate.
NOTE:
•When the parking brake is applied and the transmission
is placed in gear, the “Brake Warning Light” will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.
• This light only shows that the parking brake is applied.
It does not show the degree of brake application. When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
•
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving unattended
children in a vehicle is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter-N-Go in the
