SYSTEM SCOPE OF USE AND WARNINGS
The SmarTire
®
System and Tire Maintenance
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. 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.
System Installation and Usage
Use of the SmarTire
®
system requires that it has been properly installed and
programmed by qualified personnel according to SmarTire Systems Inc. documentation.
This includes the Owner s Manual and any supplementary installation instructions
included with system components.
Warnings
1. When an alert or warning conditions is detected, reduce vehicle speed to an
appropriate safe level and proceed to a safe stopping location or facility where
the tire can be inspected and serviced.
2. The pressure deviation alert indicates that the pressure has dropped a selected
amount below the required pressure for that level of tire temperature.
3. The low pressure warning indicates that the air pressure has dropped to a
selected minimum.
4. The high temperature warning indicates that the contained air temperature has
exceeded the selected maximum. A tire temperature buildup can be caused by a
number of factors including severe under inflation, hard sustained braking,
vehicle overload and sustained high speeds.

Introduction
FULL FUNCTION DISPLAY FEATURES
The Full Function Display adds additional features to a previously installed SmarTire
system (refer to the Tire Pressure Monitoring System Owner’s Manual ). It provides
digital tire pressure and temperature data for up to 20 tire positions as well as
enabling warning level adjustment to suit driver needs.
The system’s modular design offers two digital display units. One clips onto the basic
receiver, while the other can be remotely located with an interconnecting cable.

POWER STAGES
The Full Function Display has an energy saving feature that turns lights on to full
intensity (Active stage) only when required to display alert conditions or program
the unit. The unit automatically switches to lower power stages when no control
activity is detected.

Operation
GETTING STARTED
Mount the display unit and connect to power source.
When power is applied to the receiver, the Full
Function Display momentarily turns on all icons,
beeps, and the alarm light blinks once. The unit
then goes into stand-by mode waiting for data
from the wheel transmitters.
Until the vehicle is in motion no data will be
received from any installed transmitter. The
display will remain blank as shown.
The respective tire icon is filled in as soon as data
from its transmitter is received. The windshield/
louver is shown for any towing vehicle transmitter.
After data from all transmitters is received the
display will be in the state shown at left until an
alert or warning condition is detected.
(Normal Mode)
Data from a towed vehicle is indicated by tire
icons with no windshield/louver icon.
Note: The system will alternate views between
the towing and towed vehicle when operating
with this configuration.

CHECKING TIRE CONDITIONS
Press the TIRE button to scroll through
the tires.
Press the MODE button to scroll through
the pressure, temperature, and pressure
deviation readings for a selected tire.
Press SET button to return to normal mode.
No data received from a selected tire is shown as
dashes “---”.

Alerts and Warnings
PRESSURE DEVIATION ALERT
The Pressure Deviation Alert is initiated
when the measured tire pressure deviates
from the required pressure by more than the pre-
set level.
The alarm light turns on and alert indicator flashes
on and off. The audible alarm sounds once and
the digital readout displays the amount of
deviation e.g. -6 PSI from required pressure.
Press any button to acknowledge the alert and
stop the flashing; the alarm light remains on and
the system returns to normal mode.
Example:
Pressure Deviation Alert Level = +- 6 PSI (0.41 Bar)
Required Pressure = 35 PSI (2.40 Bar)
Actual Pressure in a wheel drops to 29 PSI (2 Bar)
Pressure Deviation reading (as shown) will be
-6 PSI (0.41 Bar)
When the alert occurs, reduce speed and proceed
to a safe location to check tires.
The Pressure Deviation Alert is cancelled when
the tires are properly re-inflated to correct levels.
-6 PSI = -.41 Bar

11
LOW PRESSURE WARNING
A Low Pressure Warning is initiated when the
pressure drops below the programmed level.
The alarm light, low pressure warning icons and
the audible alarm turn on and off continuously.
Press any button to acknowledge and stop the
flashing. The alarm light remains on and the
display reverts to a normal mode.
When the alert occurs, reduce speed and proceed
to a safe location to check tires.
The Pressure Deviation Alert is cancelled when
the tires are properly re-inflated to correct levels.
HIGH TEMPERATURE ALERT
The High Temperature Alert is initiated when
the air temperature within a tire exceeds
the programmed level.
The temperature alert icon and audible alarm
turn on and off continuously. Press any button to
acknowledge the alert and stop the flashing. The
alarm light remains on and the display reverts to
a normal mode.
When the alert occurs, reduce speed and proceed
to a safe location to check tires.
The Pressure Deviation Alert is cancelled when
the tires are properly re-inflated to correct levels.

SMARTIRE SYSTEMS INC.
UNDERSTANDING TEMPERATURE COMPENSATED
PRESSURE READINGS
An important feature of the SmarTire Full Function Display system is that pressure
deviation alerts are initiated from a comparison of the temperature compensated
pressure to the measured tire pressure read by the sensor.
The reference pressure, or “cold pressure”is the air pressure inside the tire inflated
at room temperature (64˚F or 18˚C) to the vehicle manufacturer’s recommendation.
When a tire heats up, the air pressure inside the tire can also be expected to increase.
For example, a normal or “required”pressure at 64˚F or 18˚C may be 34 PSI or
2.35 Bar and a normal pressure at 120˚F or 49˚C may be 39 PSI or 2.7 Bar. Both
pressure readings are correct at their respective temperatures.
The amount of deviation from the required pressure (at any temperature) can be
read by using the Pressure Deviation mode of this SmarTire product. If at any time
you are uncertain that the Actual Pressure reading on the display indicates the
correct tire pressure, switch to the Pressure Deviation (
+- ) readout. A blank display
indicates that the reading on the display is the correct one. Any (+) or (-) value
indicates the tire pressure is incorrect by that value. This value can then be used to
correctly inflate the tire.
