Tire pressure monitoring system
UJ General notes
Each tire, including t he spare (if provided),
should be checked monthly when cold and inflat
e d to the inflation pressure recommended by the
veh icle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the veh icle placard or t ire inflation pressure la
be l, you shou ld determine the prope r ti re infla
tion pressure fo r those t ires) .
As an added safety feature , your veh icle has been
equ ipped w ith a t ire pressure monitoring system
(TPMS) that illuminates a low tire p ress ure te ll
tale whe n one or more of yo ur t ires is significant
l y under- infla ted . Accordingly, when the low tire
p ressure tellta le ill uminates, yo u should stop and
check your tires as soon as possible, and inflate
them to the proper press ure. Driving on a s ignifi
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
p ing ability.
P lease 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 p ressure,
even if u nder-inflation has not reached t he leve l
to tr igger illum inat io n of the TPMS low tire p res
sure telltale.
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion ind icator to indicate when the sys
tem is not operat ing properly. The TPMS ma l
f u nction indicator is combined w ith the low tire
p ressure tellta le. Whe n the system de tects a
mal function, the te lltale will flash fo r approxi
mate ly one min ute and then remain continuo usly
illum inated. This sequence will continue upon
subseq uent veh icle start-ups as long as the ma l
function ex ists .
When the malfunction indicator is ill uminated,
the system may not be ab le to detect or signa l
low tire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, including the
Wh eel s
insta llation o f replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning p roper ly . Always check the
TPMS ma lfunction te lltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the rep lacement or a lternate tires a nd
wheels allow the TPMS to continue to fu nction
prope rly .
If the tire pressure monitoring 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 .
Using the ABS se nsors, the t ire pressu re moni to r
i ng system compares the tire tread circumfer
en ce and vibr ation character ist ics of the ind ividu
al tires . If the press ure changes in one o r more
t ires , th is is indicated in the instrument cluster
display with an indicato r light
[I] and a message.
If only one tire is affected, the location of that
t ire will be indicated.
T he tire press ures must be stored in the Infotain
ment system again each time the p ressures
change (switching between partial and full load
pressure) or after changing or replac ing a tire on
your vehicle
c:> page 352. The tire pressure mon i
tor ing system on ly mon itors the tire pressure you
have stored . Refer to the t ire pressu re label fo r
the re commended t ire pressu re fo r yo ur vehicle

T ire tread c irc umference and vibra tion characte r
ist ics can change and ca use a tire press ure wa rn

- the t ire pressure in one or more tires is too low
- the t ires have structural damage
- the t ire was rep laced or the t ire pressu re was
changed and it was not stored
