Only check tire pressure when the tires are cold.
Conditions for cold tires:
R The vehicle has been par ked with the tires out
of direct sunlight for at least thre e hours.
R The vehicle has tr aveled less than 1 mile
(1.6 km).
A rise in the tire temp erature of 18°F (10°C)
increases the tire pressure byappr ox.10 kPa
(0.1 bar/1.5 psi). Take this into account when

WARNING Risk of accident due to
unsuitable accesso ries on tire valve
If yo u mount unsuitable accesso ries onto tire
va lves, the tire valves may be overloaded and
malfunction, which can cause a loss of tire
pressure. Af term arke t tire pressure moni tor‐
ing sy stems will cause the tire valve toremain
open, depending on the design. This can also
re sult in a loss of tire pressure. #

DANG ER Risk of accident due toincor‐
re ct tire pressure
Each tire, including the spare (if pr ovided),
should be checked monthly when cold and
inflated tothe inflation pressure recommen‐
ded bytheve hicle manufacturer on theve hi‐
cle placard or tire inflation pressure label. (If
yo ur vehicle has tires of a dif fere nt size than
th e size indicated on theve hicle placard or
tire inflation pressure label, you should de ter‐ mine
the proper tire inflation pressure for
th 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 telltale when one or more of your
tires is significantly unde r-inflated. Accord‐
ingly, when the low tire pressure telltale illu‐
minates, you should stop and check your tires
as soon as possible, and inflate them tothe
proper pressure. Driving on a significantly
under-inflated tire causes the tire toove rheat
and can lead totire failure. Under-inf lation
also reduces fuel ef ficiency and tire tread li fe,
and may af fect theve hicle's handling and
st opping ability. Please no tethat the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility tomaintain
cor rect tire pressure, even if under-inflation 314

tion of the TPMS low tire pressure telltale.
Yo ur vehicle has also been equipped with a
TPMS malfunction indicator toindicate that
th e sy stem is not operating properly. The
TPMS malfunction indicator is combined with
th e low tire pressure telltale. When the sys‐
te m de tects a malfunction, the indicator lamp
will flash for appro ximately one minute and
th en 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 pressure as intended. TPMS mal‐
functions may occur for a variet y of reasons,
including the ins tallation of replacement or
alternate tires or wheels on theve hicle that
pr ev ent the TPMS from functioning properly.
Alw aysch eck the TPMS malfunction telltale
af te rre placing one or more tires or wheels on
yo ur vehicle toensure that there placement
or alternate tires and wheels allow the TPMS
to continue tofunction properly. The sy
stem checks the tire pressure and thete m‐
perature of the tires ins talled on theve hicle by
means of a tire pressure sensor.
New tire pressure sensors, e.g. in winter tires,
are automatically taught-in during thefirs t jour‐
ney they are used.
The tire pressure and the tire temp erature appear
in the multifunction display (/ page177).
If th ere is a subs tantial loss of tire pressure, a
wa rning is issued:
