HIGH TIRE PRESSURE
will hear two chimes when this message is displayed. To
acknowledge the warning, press RESET. After you press
RESET, a message will reappear every 10 minutes until
this condition changes. This message indicates that the
pressure in one of your tires is higher than 42 psi
(290 kPa). Next to the HIGH TIRE PRESSURE
message, you can see either LF (left front), LR (left
rear), RF (right front) or RR (right rear) to indicate to
you which tire is higher than 42 psi (290 kPa). You can
receive more than one tire pressure message at a time.
To read other messages that may have been sent at the
same time, press RESET. If a tire pressure message
appears on the DIC, stop as soon as you can. Have the
tire pressures checked and set to those shown on your
Tire Loading Information Label. See "Extended
Mobility Tires" and "Tire Inflation" in the Index.

(LF, LR, RF, RR): You SERVICE TIRE MON SYS: If this message
comes on, a part on the Tire Pressure Monitor (TPM)
is not working properly. If you drive your vehicle while
any of the four sensors are missing or inoperable, the
warning will come on in approximately 10 minutes.
If all four sensors are missing, the warning will come
on in approximately 15 to 20 minutes. (All the sensors
would be missing, for example, if you put different
wheels on your vehicle without transferring the sensors.)
If the warning comes on and stays on, there may be a
problem with the TPM. See your dealer.
