WARNING Risk of accident due toinsuf‐
fi cient or excessive tire pressure
Underinfla ted or overinfla ted tires pose the
fo llowing risks:
R The tires may bur st, especially as the load
and vehicle speed increase.
R The tires may wearexcessively and/or
une venly, which may greatly impair tire
traction.
R The driving characteristics, as well as
st eering and braking, may be greatly
impaired. #
Comply with there commended tire
pressure and check the tire pressure of
all tires including the spare wheel regu‐
larly:
R at least once a month
R when the load changes
R before embarking on a lon ger journey
R if operating conditions change, e.g. off-
ro ad driving #
Adjust the tire pressure as necessar y. Driving wi
thtire pressure that is too high or too
low has thefo llowing consequences:
R Shor tenth e service life of the tires.
R Cause increased tire damage.
R Adversely af fect handling characteristics and
th us driving saf ety, e.g. due tohydroplaning. &
WARNING Risk of an accident due to
insuf ficient tire pressure
Ti re s with pressure that is too low can over‐
heat and bur stas a result.
In addition, they also suf fer from excessive
and/or ir regular wear, which can significantly
impair the braking properties and the han‐
dling characteristics. #
Avoid excessively low tire pressures in
all the tires, including the spare wheel. Ti
re pressure which is too low can cause:
R Tire faults as a result of overheating
R Impaired handling characteristics
R Irre gular wear
R Increased fuel consum ption &
WARNING Risk of accident from exces‐
sive tire pressu re
Ti re s with excessively high pressure can bur st
because they are damaged more easily by
highw ayfill, pot holes etc.
In addition, they also suf fer from ir regular
we ar, which can significantly impair the brak‐

Each tire, including the spare (if pr ovided),
should be checked monthly when cold and

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

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

Adjust the tire pressure as necessar y. The
temp erature grades are A (highest grade), B

and its ability torelease heat on a specified test
wheel in laboratory tests under contro lled condi‐
