TIRE PRESSURE MONITOR SYSTEM
(TPMS)
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
The tire pressure will vary with temperature by about
0.07 BAR for every 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 1.6 km after a
three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure
molded into the tire sidewall. Refer to “Tires – General
Information” in “Technical Specifications” for informa-
tion on how to properly inflate the vehicle’s tires. The
tire pressure will also increase as the vehicle is driven.
This is normal and there should be no adjustment for
this increased pressure.
The TPMS will warn the driver of a low tire pressure if
the 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
tire pressure warning (Tire Pressure Monitoring Tell-
tale Light) illuminates, you must increase the tire pres-
sure to the recommended cold placard pressure in
order for the Tire Pressure Monitoring Telltale Light to
turn off. The system will automatically update and the
Tire Pressure Monitoring Telltale 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 25 km/h in order for the TPMS to receive this
information.
