Tire pressure
monitoring system
(D General notes
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in­
flated to the inflation pressure recommended 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 in­
flation pressure label, you shou ld determine
the proper tire inflation pressure for those
tires).
As an added safety feature, your vehicle has
been equipped with a tire pressure monitor ing
system (TPMS) that illuminates a low tire
p ressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you should stop and check your tires as
soon as possible, and inflate them to the proper pressure. Driving on a significantly un­
der-inflated tire causes the tire to overheat
and can lead to tire failure . Under -inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ab ility.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped w ith a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, the te lltale will
flash for approximately one minute and then remain continuously illuminated. This se- quence will continue upon subsequent vehicle
start-ups as
long as the malfunction exists.
When the malfunction indicator is illum inat­
ed, the system may not be ab le to detect or
signal low tire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement o r alternate ti res and wheels allow
the TPM S to cont inue to function properly.
Description
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the
temperature and pressure in the tires. Theda­
ta is sent from these sensors to the control
module by radio frequency.
The tire pressure monitoring system shows
the current pressures and temperatures of the
tires in the Infotainment system
¢page 247.
It also compares the current tire pressures
with the stored pressures and gives a warning in the driver information system if the tire
pressure is different from what is stored
¢ page 247.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures. You must resave the tire pressures
¢page 248:
- eve ry time the tire p ressu res change, for ex­
ample when the load in the vehicle changes,
- after replacing a t ire, or
- if wheels w ith new wheel sensors are used .
_&. WARNING
-The tire pressu re monitoring sys tem as­
sists the driver in monitoring tire pres­
sures. The driver is responsible for having
the tires inflated to the correct pressure. ..,.
