Jeep Grand Cherokee, Owner'S Manual

NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or 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.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•
The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire gauge, even
if under-inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring Telltale
Light.
•
Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an audible
chime will be activated, when one or more of the four
active road tire pressures are low. In addition, the EVIC will
display a “LOW TIRE PRESSURE” message for a minimum
of five seconds, an
⬙
Inflate Tire to XXX
⬙
message and a
graphic display of the pressure value(s) with the low tire(s)
displayed in a different color. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your Instru-
ment Panel” for further information.
NOTE: Your system can be set to display pressure units
in PSI or kPa.
