No ise or unusual handling ch aracteristics
While driving, pay attention to vibrations, noises
and unusual handling ch aracteristics, e.g. pulling
to one side. This may indicate th at th e wheels or
tires are damaged. If yo u suspect th at a tire is
defective, re duce yo ur speed immediatel y. St op
th e ve hicle as soon as possible to ch eck th e
wheels and tires fo r dama ge . Hidden tire dam‐
age could also be causing th e unusual handling
ch aracteristics. If yo u fi nd no signs of damage,
ha ve th e tires and wheels ch ec ke d at a qu alified
specialist wo rk shop.

tire pressure fo r all tires app ro ve d fo r th is ve hi‐

cold tires under va ri ous operating conditions, i.e.
loading and/or speed of th e ve hicle.
If one or more tire sizes precede a tire pressure,
th e tire pressure information fo llowing is only

The load conditions "partially laden" and "fully

DA NG ER Risk of accident due to incor‐
re ct tire pressure
Every tire, including th e spare (if pr ov ided),
should be ch ec ke d when cold at least once a
month and inflated to th e pressure re com‐
mended by th e ve hicle manufacturer (see
Ti re and Loading In fo rm ation placard on th e
B-pillar on th e driver ’s side or th e tire pres‐
sure label on th e inside of th e fuel fi ller fl ap
of yo ur ve hicle). If yo ur ve hicle has tires of a
dif fe re nt size th an th e size indicated on th e
Ti re and Loading In fo rm ation placard or th e tire pressu re ta ble, yo u need to de te rm ine
th e proper tire pressure fo r th ose tires.
As an added saf et y fe ature, yo ur ve hicle has
been equipped with a tire pressure monitor‐
ing sy st em (TPMS) th at illuminates a low tire
pressure indicator lamp when one or more of
yo ur tires are sign if icantly underinflated.
Ac cording ly , if th e low tire pressure indicator
lamp lights up, yo u should st op and ch eck
yo ur tires as soon as possible, and inflate
th em to th e proper pressure. Driving on a
significant ly underinflated tire causes th e tire
to ove rh eat and can lead to tire fa ilure.
Und erinflation also increases fuel consump‐
tion and re duces tire tread life, and may
af fe ct th e ve hicle's handling and braking abil‐
ity. Please no te th at th e TPMS is not a substi‐
tute fo r proper tire maintenance, and it is th e
driver's re sponsibility to maintain cor re ct tire
pressure, ev en if underinflation has not
re ached th e le ve l to trig ge r illumination of
th e TPMS low tire pressure indicator lamp.
Yo ur ve hicle has also been equipped with a
TPMS malfunction indicator to indicate when th e sy st em is not operating properly. The
TPMS malfunction indicator is combined with
th e low tire pressure indicator lamp. When
th e sy st em de te cts a malfunction, th e indica‐
to r lamp will fl ash fo r app ro xima te ly a minute
and th en re main continuously illumina te d.
This sequence will continue upon subsequent
ve hicle st art-ups as long as th e malfunction
ex ists.
When th e malfunction indicator is illumina‐
te d, th e sy st em may not be able to de te ct or
signal low tire pressure as intended. TPMS
malfunctions may occur fo r a va ri et y of re a‐
sons, including th e ins ta llation of incompati‐
ble re placement or alternate tires or wheels
on th e ve hicle th at pr ev ent th e TPMS from
functioning proper ly .
Alw ay s ch eck th e TPMS malfunction wa rn ing
lamp af te r re placing one or more tires or
wheels on yo ur ve hicle to ensure th at th e
re placement or alternate tires and wheels
allow th e TPMS to continue to function prop‐
