Telltale Light” will be OFF as long as no road tire(s) are
below the low pressure warning threshold. The vehicle
may need to be driven for up to 10 minutes above 15 mph
(24 km/h) to receive this information.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
After-market 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.
CAUTION!
After inspecting or adjusting the tire pressure al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, nor to provide warning of a tire
failure or condition.
•
The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•
Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
