DANG ER Risk of accident due toincor‐
re ct tire pressure
Every tire, including the spare (if pr ovided),
should be checked when cold at least once a
month and inflated tothe pressure recom‐
mended bytheve hicle manufacturer (see Tire
and Loading In form ation placard on the B-pil‐
lar on the driver ’sside or the tire pressure
label on the inside of the fuel filler flap of your
ve hicle). If your vehicle has tires of a dif fere nt
size than the size indicated on theTire and
Loading In form ation placard or the tire pres‐
sure table, you need todeterm ine the proper
tire pressure forth ose tires.
As an added saf etyfe ature, your vehicle has
been equipped with a tire pressure monitor‐ ing sy
stem (TPMS) that illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are significantly unde rinfla ted.
Ac cording ly, if the low tire pressure indicator
lamp lights up, you should stop and check
yo ur tires as soon as possible, and inflate
th em tothe proper pressure. Driving on a sig‐
nificant lyunde rinfla ted tire causes the tire to
ove rheat and can lead totire failure. Underin‐
fl ation also inc reases fuel consum ption and
re duces tire tread life, and may af fect the
ve hicle's handling and braking ability. Please
no te that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
re sponsibility tomaintain cor rect tire pres‐
sure, even if underinflation has not reached
th e le velto trig ger illumination of the TPMS
low tire pressure indicator lamp.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate when
th e sy stem is not operating properly. The
TPMS malfunction indicator is combined with
th e low tire pressure indicator lamp. When
th e sy stem de tects a malfunction, the indica‐
to r lamp will flash for appro ximately a minute
and then remain continuously illumina ted.
This sequence will continue upon subsequent
ve hicle start-ups as long as the malfunction
ex ists.
When the malfunction indicator is illuminated,
th e sy stem may not be able todetect or sig‐
nal low tire pressu reas intended. TPMS mal‐
functions may occur for a variet y of reasons,
including the ins tallation of incompatible 238

placement or alternate tires or wheels on
th eve hicle that pr event the TPMS from func‐
tioning proper ly.
Alw aysch eck the TPMS malfunction warning
lamp af terre placing one or more tires or
wheels on your vehicle toensure that the
re placement or alternate tires and wheels
allow the TPMS tocontinue tofunction prop‐
er ly. The sy
stem checks the tire pressure and thete m‐
perature of the tires ins talled totheve hicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in thefirs t time they are
driven.
The tire pressure and the tire temp erature appear
in the multifunction display (/ page165).
If th ere is a subs tantial loss of tire pressure, a
wa rning is issued:
