Tire Pressure Monitoring System (Tpms) - RAM 2500 2023 Owner's Manual

If a PEB event begins at a speed below 39 mph (62 km/h),
the system may provide maximum braking to mitigate the
potential collision with a pedestrian/cyclist. If the PEB
event stops the vehicle completely, the system will hold
the vehicle at a standstill for two seconds and then
release the brakes. When the system determines a
collision with the pedestrian/cyclist in front of you is no
longer probable, the warning message will be deactivated.
The minimum speed for PEB activation is 3 mph (5 km/h).
WARNING!
Pedestrian Emergency Braking (PEB) is not intended to
avoid a collision on its own, nor can PEB detect every
type of potential collision with a pedestrian/cyclist. The
driver has the responsibility to avoid a collision by
controlling the vehicle via braking and steering. Failure
to follow this warning could lead to serious injury or
death.
Turning PEB On Or Off
NOTE:
The default status of PEB is "On." This allows the system
to warn you of a possible frontal collision with the pedes-
trian/cyclist.
The PEB button is located in the Uconnect display in the
Control settings page 226.
Ú
To turn the PEB system off, push the Pedestrian
Emergency Braking button.
To turn the PEB system back on, push the Warning Active
Braking button.
Changing the PEB status to "Off" deactivates the system,
so no warning or active braking will be available in case of
a possible frontal collision with the pedestrian/cyclist.
NOTE:
The PEB system will retain the last setting selected by the
driver after ignition shut down. The system will not reset to
the default setting when the vehicle is restarted.

IRE RESSURE ONITORING
(TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
NOTE:
The TPMS Warning Light will illuminate in the instrument
cluster and a chime will sound when tire pressure is low in
one or more of the four active road tires. In addition, the
instrument cluster will display a graphic showing the
pressure values of each tire with the low tire pressure
values in a different color, or the Uconnect radio will
display a TPMS message. When this occurs you must
increase the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning Light to
turn off.
The tire pressure will vary with temperature by about 1 psi
(7 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three hour period.
The cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle is
driven — this is normal and there should be no adjustment
for this increased pressure.
See page 416 on how to properly inflate the vehicle's
Ú
tires.
S The TPMS will warn the driver of a low tire pressure if the
YSTEM
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low TPMS Warning Light
illuminates, you must increase the tire pressure to the
recommended cold placard pressure in order for the
TPMS Warning Light to turn off. The system will
automatically update and the TPMS Warning Light will turn
off once the system receives the updated tire pressures.
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
TPMS Warning Light off.
