TIRE PRESSURE MONITORING
SYSTEM (TPMS)
The following information applies to the On-Screen
TPMS version.

ON-SCREEN TPMS VERSION

This system is a sensing device designed to
identify and display tire operating data and activate
an alert or warning when pressure or temperature
irregularities are detected.
NOTE
It is the responsibility of the driver to react
promptly and with discretion to alerts and
warnings. Abnormal tire inflation pressures
should be corrected at the earliest opportunity.
Instrument Cluster Alarms And Warnings
Visual and audible warnings turn on to indicate
either a low tire pressure or high tire temperature
through two different warning conditions:
1- LOW TIRE PRESSURE WARNING
on + on + audible warning
Indicates a low tire pressure. Refer to the
dedicated display to determine whether the
warning condition is critical or not.
2- HIGH TIRE TEMPERATURE WARNING
flashing +
A high temperature warning will trigger if a tire
temperature rises above 194°F (90°C). You
should stop the vehicle as soon as possible
and check your tires.
Dedicated Display
The TPMS display knows where the sensors are
located. It receives the raw temperature and
pressure readings from the TPMS receiver, it
reads several signals from the vehicle and does
the calculation required to generate the various
screens.

When no readings have been received for a tire
location or when the received data correspond to a
parameter range defined as unavailable, then the
reading is considered as not available and appears
as two dash lines "_ _".
The TPMS display is initially configured to define
how many axles and running tires are present on the
vehicle. For current Prevost vehicle models, there
are two axles /
configurations are:
CONFIGURATION 1: Axle 1 (Front) Two tires, Axle
2 (Drive) 4 tires, Axle 3 (Tag) 2 tires.
CONFIGURATION 2: Axle 1 (Front) Two tires, Axle
2 (Drive) 2 tires (super Singles), Axle 3 (Tag) 2 tires.
The TPMS display is also configured with several
other parameters, including threshold levels for the
alarms.
The TPMS display turns OFF when the ignition
key is switched OFF.
Operation
The system will monitor all vehicle tires (6 or 8)
plus the spare tire when a spare is supplied.
NOTE
Some vehicle models do not come with a spare
tire.
There are two configurations of vehicle tires to be
supported. One configuration (the most common)
consists of 8 tires total: two tires on the front axle,
4 tires on the drive axle and 2 tires on tag axle. All
screen figures shown in this document relates to
this vehicle configuration. The second tire
