WARNING Risk of inju ryfrom pla stic
parts breaking off af terth e use of sol‐
ve nt-based care products
Ca reand cleaning products con taining sol‐
ve nts can cause su rfaces in the cockpit to
become porous. When
the airbags are deplo yed, plastic parts
may break away. #
Do not use any care or cleaning prod‐
ucts containing sol vents toclean the
cockpit. &
WARNING Risk of inju ryor death from
bleached seat belts
Bleaching or dyeing seat belts can se verely
we aken them.
This can, forex ample, cause seat belts to
te ar or fail in an accident. #
Never blea chor dye seat belts. Obser

If yo u come into contact with the tire sealant,
obser vethefo llowing: #
Rinse off the tire sealant from your skin
immediately using water. #
If tire sealant gets into your eyes, thor‐
oughly rinse out theey es using clean
wate r. #
If tire sealant has been swallowe d,
immediately rinse out the mouth thor‐
oughly and drink plenty of water.Do not
induce vomiting and seek medical
attention immediately. #

The tires may wearexc essively and/or
une venly, which may greatlyimpair 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 pressu rethat is too high or too
low can:
R Sho rten the service life of the tires.
R Cause increased tire damage. R
Adversely af fect driving characteristics and
th us driving saf ety, e.g. due to hydroplaning. &
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 defects 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 pressure
Ti re s with excessively high pressure can
bu rst 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‐
ing properties and the handling characteris‐
tics. #
Avoid excessively high tire pressures in
all the tires, including the spare wheel. Excessively high tire pressure can
result in:
R Increased braking dis tance
R Impaired handling characteristics
R Irre gular wear
R Impaired driving com fort

The relative per form ance of tires depends upon
th e actual conditions of their use, ho wever,and
may depart significantly from the norm due to
va riations in driving habits, service practices and
dif fere nces in road characteristics and climate
conditions.
Tr action grade &
DANG ER Risk of accident due toinade‐
qu ate traction
The traction grade assigned tothis tire is
based on stra ight-ahead braking traction
te sts, and does not include either accelera‐
tion, cornering, hydroplaning or peak traction
ch aracteristics. #

drive at a speed tosuit the pr evailing

NO
TEDama getothe driv etra in from
wheelspin #
Avoid wheelspin. The traction grades – from highest
tolowest –
are AA, A,B and C. Those grades represent the
tire's ability tostop on wet pa vement as meas‐
ured under controlled conditions on specified
go vernment test sur faces made of asphalt and
concr ete.
Te mp erature grade &
WARNING Risk of accident from tire
ove rheating and tire failure
The temp erature grade forth is tire is es tab‐
lished for a tire that is proper ly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately
or in combination, can cause excessive heat
build-up and possible tire failure. #
Obser vethere commended tire pres‐
su res and regularly check the tire pres‐ sure of all tires including
the spare
wheel. #
Adjust the tire pressure as necessar y. The
temp erature grades are A (the highest), B
and C. They represent the tire's resis tance tothe
ge neration of heat and its ability todissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel. Sus‐
ta ined high temp erature can cause the material
of the tire todegenerate and reduce tire life, and
exc essive temp erature can lead tosudden tire
fa ilure. Grade C cor responds toa le vel of per‐
fo rm ance which all passenger car tires must
