2021 RAM 1500 spare tire

330SAFETY
Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value as shown in the "Inflate to XX" message.
Once the system receives the updated tire
pressures, the system will automatically
update, the graphic display in the instrument
cluster will return to its original color, and the
Tire Pressure Monitoring System Warning Light
will turn off. 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.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the Tire Pressure Moni -
toring System Warning Light off.
Service TPMS Warning
If a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning 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 "SERVICE TPMS 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 System Warning Light will
no longer flash, and the "SERVICE TPMS
SYSTEM" message 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 Tire Pressure Moni
-
toring System sensors
Installing aftermarket window tinting that
contains materials 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 TPMS
sensors A system fault may occur due to an incorrect
TPMS sensor location condition. When a system
fault occurs due to an incorrect TPMS sensor
location, the Tire Pressure Monitoring System
(TPMS) Warning 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 System Warning 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 TPMS 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 Tire Pressure Monitoring System
(TPMS) Warning Light and a “LOW TIRE”
message will remain on and a chime will
sound. In addition, the graphic in the instru -
ment cluster will still display a pressure value
in a different color and an “Inflate to XX”
message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure
Monitoring System (TPMS) Warning Light will
flash on and off for 75 seconds and then
remain on solid. In addition, the instrument
cluster will display a "SERVICE TPMS
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 Tire Pressure Moni -
toring System (TPMS) Warning Light will flash
on and off for 75 seconds and then remain
on solid, and the instrument cluster will
display a "SERVICE TPMS 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 Tire Pressure Monitoring
System (TPMS) Warning 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 Fill Alert
This feature notifies the user when the placard
tire pressure is attained while inflating or
deflating the tire.
You may choose to disable or enable the Tire Fill
Alert feature through use of the Uconnect
Settings in the radio.
NOTE:
Only one tire can be filled at a time when
using the Tire Fill Alert system.
The Tire Fill Alert feature cannot be entered if
an existing TPMS fault is set to “active” or if
the system is in deactivation mode (if
equipped).
The system will be activated when a positive
increase in tire pressure is detected by the
TPMS while inflating the tire. The ignition must
be in the RUN mode, with the transmission in
PARK.
NOTE:
It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster.
If the hazard lamps do not come on while
inflating the tire, the TPMS sensor may be out of
range preventing the TPMS sensor signal from
being received. In this case, the vehicle may
need to be moved either forward or backward
slightly to exit the null spot.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE 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 lug nut/bolt torque 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.
EXHAUST GAS The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have an authorized dealer inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each time
the vehicle is raised for lubrication or oil
change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you.
To avoid breathing (CO), follow these safety
tips:
Do not run the engine in a closed garage or
in confined areas any longer than needed
to move your vehicle in or out of the area.
If you are required to drive with the trunk/
liftgate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO
NOT use the recirculation mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force outside
air into the vehicle. Set the blower at high
speed.
