General notes
Each tire, includ ing the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended
by the
vehicle manufacturer on the vehicle placard or
tire inf lat ion pressure label. (If your veh icle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
be l, you shou ld determine the proper tire infla-
tion 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 tell-
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 poss ible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to t ire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the veh icle's handling and stop-
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the dr iver's re-
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to trigger illuminat ion of the TPMS low t ire pres-
sure telltale.
Your veh icle has also been equ ipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated . This sequence will cont inue 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, including the
insta llation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more t ires or wheels on your veh icle to ensure
that the replacement or alternate t ires 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. 199 Instrument cluster: ind icator light with message
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires . If the pressure changes in one or more
t ires, this is indicated in the instrument cluster
display with an indicator light

and a message.
If only one tire is affected, the location of that
tire will be ind icated.
The tire pressures 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 rep lacing a tire on
your vehicle
