Tire pressure monitoring system *
Applies to vehicles: with tire pressu re mon ito ring system
General notes _J
Each tire, including the spare (if provided), should be checked
month ly when cold and inflated to the inflation pressure recom
mended by the vehicle manufacturer 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 inflation pres
sure 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 tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low t ire pressure te llta le i llu
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure . Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire
failure . Under -inflation also reduces fue l 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 mainte
nance, and it is the driver's responsibi lity to maintain correct tire
pressure, even if under -inflation has not reached the leve l to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction indi
cator to indica te when the system is not opera ting proper ly . The
T PMS malfunction indicator is combined with the low tire pressure
t elltale. When the system detects a ma lfunction, the telltale w ill
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
be ab le to detect or signa l low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, inc luding the insta
llation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction telltale after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TP MS to continue to function
proper ly. •
App lies to veh ic les: w ith tire pressure monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitor ing syste m senses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbols appear in the ins trument c luster dis play to alert the d river .
The warning light in the instrument cluster comes on when the
t ire is sig nificantly unde rinflated
~ page 12 .
The warn ing light { also i lluminates in the case of a system
malfunction.
Be aware that tire p ressu re is also dependent on the tempe ra ture of
the tire . For every 18 °F (1 O °Cl increase in tire temperature, tire pres
su re increases by about 1 .5 psi (0 .1 bar). The ti re wa rms up wh ile the
vehicle is moving and tire pressure rises. So you should adjust tire pressure only when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali
brated, tire pressure on all fou r tires sh ould be checked at regular
interva ls, adjusted if necessary, and saved in the proper setting
(recommended pressure)~

The tire pressure is shown either on the driver's side B-pil lar or on
the inside of the fuel filler f lap . _..
