2016 Ram ProMaster City sensor

driven for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
30 psi (207 kPa). If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 27 psi (186 kPa), a
temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 23 psi (159 kPa). This tire
pressure is sufficiently low enough to turn on the Tire
Pressure Monitoring Telltale Light. Driving the vehicle
may cause the tire pressure to rise to approximately 27
psi (186 kPa), but the Tire Pressure Monitoring Telltale
Light will still be on. In this situation, the Tire Pressure
Monitoring Telltale Light will turn off only after the tires
are inflated to the vehicle’s recommended cold tire pres-
sure value.CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have
your sensor function checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve

stem, which could damage the Tire Pressure Moni-
toring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
System Operation
This is the TPMS warning indicator located in the
instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.

STARTING AND OPERATING 281

NOTE:It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Five Tire Pressure Monitoring Sensors. (If Equipped
with Spare Tire)
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an audible chime will be
activated, and a proper text message will be displayed
when one or more of the four active road tire pressures
are low. Should this occur, you should stop as soon as
possible, check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s recom-
mended cold placard pressure value. The system will automatically update and the Tire Pressure Monitoring
Light will extinguish once the updated tire pressures
have been received. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) to receive
this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a system
fault is detected, an audible chime will be activated and
a proper text message will be displayed. If the ignition
key is cycled, this sequence will repeat providing the
system fault still exists. The Tire Pressure Monitoring
Telltale Light will turn off when the fault condition no
longer exists. A system fault can occur with any of the
following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
282 STARTING AND OPERATING

2. Installing some form of aftermarket window tintingthat affects radio wave signals.
3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle can be equipped with either Tire
Service Kit, compact spare tire or regular size spare tire
(with or without original TPMS sensor).
1. Tire Service Kit (original tire sealant – if equipped): After fixing the punctured tire with original tire seal-
ant, the original situation will be restored, so system
will turn off the telltale during the normal drive.
2. Compact Spare Tire – if equipped: The compact spare wheel is not equipped with TPMS sensor. So when
mounted, during the normal drive the system will
turn on the telltale (flashing for approximately 75 sec. then remains solid). This condition persists until a
wheel equipped with original TPMS sensor has been
mounted on the vehicle.
3. Regular size spare tire (not equipped with TPMS sensor): When mounted, during the normal drive the
system will turn on the telltale (flashing for approxi-
mately 75 sec. then remains solid). This condition
persists until a wheel equipped with original TPMS
sensor has been mounted on the vehicle. Then the
system will be restored and the telltale will turn off
during the normal drive.
4. Regular size spare tire (equipped with TPMS sensor): When mounted, the telltale will turn off during the
normal drive.
5. In all the above cases please check the replacement tire inflation pressure before driving your vehicle.
