General notes
Applies to vehicles: with tire pressure monitor ing system
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
f lated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has t ires of a different size than the
size indicated on the vehicle placard or tire in-
flation pressure label, you should determine
the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord ing-
ly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a significantly un-
der-inflated tire causes the tire to overheat
and can lead to tire failure . Under-inflation al-
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability .
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsib ility to ma inta in correct tire
pressure , even if under-inflation has not
reached the leve l to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not operating properly. The
TPMS malfunction indicato r is combined with
the low tire pressure telltale . When the sys-
tem detects a malfunction, the telltale will
f lash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists .
When the malfunction indicator is illuminat-
ed, the system may not be ab le to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the vehi-
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ens ure that the re-
placement or alternate ti res and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to veh icles : with tire pressu re monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.

Using the ABS sensors, the tire pressure moni-
toring system compares the tire tread circum-
ference and vibration characteristics of the in-
dividual tires. If the pressure decreases in one
or more t ires, this is ind icated in the instru-
ment cluster with a warning symbol

The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
