illuminates, 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 a l-
so reduces fuel efficiency and tire tread life,
and may affect the ve hicle's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv-
e r's responsib ility to ma inta in correct t ire
pressure, even if under- inflation has not
reac hed the level to t rigge r illumination of the
TPMS low t ire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indi cat o r is combined wit h
the low ti re pressure tell t a le . When the sys-
tem detec t s a malf unction, the te lltale will
flash for approximately one minute and t hen
remain cont inuo usly illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunctio n indicator is illuminat-
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunct ions may occur for a variety of rea-
sons, includi ng the installat io n of rep lace-
ment or alternate tires or wheels on the veh i-
cle that prevent the TPMS from funct ion ing
properly . Always chec k the TPMS malfunct ion
t ellt ale after replacing one or more t ires or
wheels on your veh icle to ensure t hat the re-
placement or a lternate tires and wheels allow
the TPMS to continue to function properly .
Introduction
The tire pressure monitoring system monitors
oir pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressure monitoring sys-
tem senses a significant loss of air pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster d is-
play to alert the driver. The
RE
warning light
Tire s an d wheel s
207
in the instrument cluster comes on when the
tire is significant ly underinflated .
The wa rning light
RE
also illumi nates in the
case of a system malfun ct ion.
Be awa re that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 °F
(10 °C) incre ase in t ire temper ature, t ire pres-
sure increases by about 1.5 psi (0 .1 bar). The
ti re warms up while the vehicle is moving and
tire press ure rises . So you sho uld adju st tire
pressure only when they a re
cold,
when the
temperature
of the tires is roughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monitoring
system properly calibrated, t ire pressu re on
a ll four tires sho uld be checked at regu lar in-
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (visible when the
door is open).
A
WARNING
When t he tire pressure mo nitoring system
war ning light is lit, one or more of your
tires is s ignificantly under-infla t ed . You
should stop and check you r tires as soon as
possib le, and inflate t hem to t he proper
pressure as indicate d on t he vehicle's t ire
press ure label
¢page 193.
Driving on a
significantly under -inflated ti re causes the
tire to over heat and can lead to tire failure.
Under-inflat ion also is likely to impair the
vehicle's handling and stopping ab ility.

For the sake of the environment
Driving wit h un d er-inflated tires red uces
fuel efficiency an d tire t read life.

Tips
- Each tire should be chec ked monthly
when the temperature
of the tires is
about the same as ambient a ir tempera-
t ure and set to the recommended infla-
tion press ure as specified on the tire
pressure label
