pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to “Tires –
General Information” in “Starting And Operating” for
information 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 adjust-
ment 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 Telltale
Light) illuminates, you must increase the tire pressure
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 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) placard pres-
sure of 33 psi (227 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn ON
the “Tire Pressure Monitoring Telltale Light.” Driving
the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 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 placard pressure 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
