_& WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed .
Tire pressure monitoring
system
CD General notes
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
veh icle manufac tu rer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inf lation pressure la-
be l, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire press ure te ll-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure tellta le illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a s ignifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to t ire failure. Unde r-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop -
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsib ility to ma inta in correct tire pressure,
even if under -inflation has not reached the level
to trigger illum inat ion of the TPMS low tire pres-
sure telltale.
Your veh icle has also bee n eq uipp ed with a TPMS
mal function indicator to indicate when the sys-
tem is not operating properly. The TPMS mal -
function indicator is combined with the low tire
pressure tellta le. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal -
function exists .
When the malfunction indicator is illuminated ,
the sys t em may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, includin g the
insta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS ma lfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function .
Fig. 197 Instrume nt cluste r: indicator light with message
Using the ABS sensors, the t ire pressure monitor-
ing system compares the tire tread circumfer-
ence and vibration characteristics of the ind ividu-
al tires. If the press ure changes in one or more
tires , this is indicated in the instrument cluster
display with an indicator light
ti] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire press ures must be stored in the Infotain-
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle¢
page 250. The tire pressure moni-
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for ..,.
