2013 DODGE VIPER TPMS

12. Tire Pressure Monitoring Telltale Light — If
Equipped
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or

alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.13. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBD, that
monitors engine control systems. The light will
illuminate when the ignition is in the ON/RUN position,
before engine start. If the bulb does not come on when
cycling the ignition from OFF to ON/RUN, have the
condition checked promptly.
Certain conditions, such as poor fuel quality, etc., may
illuminate the MIL after engine start. The vehicle should
be serviced if the light stays on through several of your
typical driving cycles. In most situations, the vehicle will
drive normally and will not require towing.

STARTING AND OPERATING 201

Refer to the “Maintenance Schedule” for the proper
maintenance interval. Remember, more frequent rotation
is permissible if desired. Also, correct for anything caus-
ing rapid or unusual wear prior to performing the tire
rotation.
NOTE:Each wheel on your vehicle contains a tire pres-
sure sensor. The Tire Pressure Monitor System (TPMS)
learns the location of each sensor though system pro-
gramming. Although not required, the manufacturer
recommends reprogramming the TPMS after rotating the
tires so that the system can relearn each sensor ’s location.
See your authorized dealer for system reprogramming.
The front and rear tires are different sizes and cannot be
used in place of each other. Rotate the tires “side-to-side”
as shown in the diagram.
TIRE PRESSURE MONITOR SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors mounted to each
wheel as part of the valve stem transmit tire pressure

readings to the receiver module. It is particularly impor-
tant for you to check the tire pressure in all of the tires on
your vehicle monthly and to maintain the proper pres-
sure. The TPMS consists of the following components:•
Receiver module, •Four TPM sensors, •Various TPMS
messages, which display in the Electronic Vehicle Infor-
mation Center (EVIC), and •TPM Telltale Light The
matching full size spare wheel and tire assembly (if
equipped) has a TPM sensor.
Tire Pressure Monitoring Low Pressure Warnings
The TPM Telltale 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 EVIC will display a LOW TIRE
message and a graphic showing the pressure values of
each tire with the low tire pressure values flashing or
changing color. Should this occur, you should stop as soon as possible
and inflate the tires with a low pressure condition (those
flashing or in a different color in the EVIC graphic) to the
vehicle’s recommended cold placard pressure inflation
value. Once the system receives the updated tire pres-
sures, the system will automatically update, the graphic
display in the EVIC will stop flashing or change color
back to the original color, and the TPM Telltale 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.
246 STARTING AND OPERATING

Service TPMS Warning
If a system fault is detected, the TPM 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
EVIC 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 TPM Telltale Light will no longer
flash, and the SERVICE TPM 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:
1. Signal interference due to electronic devices or driving next to facilities emitting the same radio frequencies as
the TPM sensors. 2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation of 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.
The EVIC will also display a SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
the SERVICE TPM SYSTEM message is displayed.
