requ irements The prescribed service inter

be per form ed more of tenth an presc ribed if the
ve hicle is operated under arduous conditions or
increased loads.
Examples of arduous operating conditions:
R regular city driving with frequent intermediate
st ops R
mainly short-dis tance driving
R frequent ope ration in mountainous terrain or
on poor road sur faces
R when the engine is of ten le ftidling for long
periods
R operation in particula rly dusty conditions
and/or if air-reci rculation mode is frequently
used
In these or similar operating conditions, ha vethe
interior air filter, engine air cleaner, engine oil and
oil filter etc. changed more frequently. If theve hi‐

If yo u open the hood when the engine has
ove rheated or during a fire inthe engine com‐

WARNING Risk of accident due toincor‐
re ct ins tallation of snow chains
Ve hicles with rear-wheel drive: ifyo u ha ve
ins talled snow chains tothe front wheels,
th ey may drag against theve hicle body or
ch assis components.
This could cause damage totheve hicle or the
tires. #
Never ins tall snow chains on the front

WARNING Risk of accident due to
unsuitable sn ow chains
Ve hicles with all-wheel drive do not ha vesuf‐
fi cient clea rance on the front axle for com‐
mercial lyavailable sn ow chains.
When you ins tall commercially available sn ow
ch ains, the snow chains may come loose and
damage chassis components or brake hoses. #

R The sn owchains must be retightened af ter
driving appr oximately 0.6 miles (1 km). This is
th e only wayto ensure the snow chains are
optimally seated with clearance toadjacent
components.
R Vehicles with all-wheel drive: install snow

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 can:
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 to hydroplaning. &
WARNING Risk of an accident due to
insuf ficient tire pressu re
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 malfunctions 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 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‐
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
R Susceptibility todamage &
WARNING Risk of accident caused by
re peated drop in tire pressure
If th e tire pressure drops repeatedly, the
wheel, valve or tire may be damaged.

Ra
ting. You can find the Gross Axle Weight Rating
on the B-pillar on the driver's side.
Speed rating: the speed rating is pa rtof the tire
identification. It specifies the speed range for
which a tire is appr oved.
GV W (Gross Vehicle Weight): the Gross Vehicle
We ight includes thewe ight of theve hicle includ‐
ing fuel, tools, the spare wheel, accessories
ins talled, occupants, luggage and the trailer
dr aw bar nose weight if applicable. The Gross Vehi‐
cle Weight must ne verex ceed the Gross Vehicle
We ight Rating (GVWR) specified on the B-pillar on
th e driver's side.
GV WR (Gross Vehicle Weight Rating): the
GV WR is the maximum permitted gross weight of
th e fully laden vehicle (weight of theve hicle
including all accessories, occupants, fuel, lug‐
ga ge and the trailer dr awbar nose weight if appli‐
cable). The Gross Vehicle Weight Rating is speci‐
fi ed on theve hicle identification plate on the B-
pillar on the driver's side.
Maximum weight of the laden vehicle: the
maximum weight is the sum of theve hicle's curb
we ight, weight of the accessories, maximum load
and thewe ight of thefa ctory ins talled optional
equipment.
Kilopascal (kPa): metric unitfor tire pressu re.
6.9 kPa are the equivalent of 1 psi. Ano ther unit
fo r tire pressu reis bar. 100 kilopascals (kPa) are
th e equivalent of 1 bar.
Load index: in additiontothe load-bearing index,
th e load index may also be imprinted on the side‐
wa ll of the tire. This specifies the load-bearing
capacity more precisel y.
Curb weight: thewe ight of a vehicle with stand‐
ard equipment including the maximum capacity
of fuel, oil and coolant. It also includes the air-
conditioning sy stem and optional equipment if
th ese are ins talled on theve hicle, but does not
include passengers or luggage.
Maximum tire load: the maximum tire load is
th e maximum permissible weight in kilog rams or
lbs for which a tire is appro ved.
Maximum permissible tire pressure: maximum
permissible tire pressure for one tire.
Maximum load on one tire: maximum load on
one tire. This is calculated bydividing the maxi‐
mum axle load for one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressu re. Aspect
ratio: relationship between tire height
and tire width in percent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the
tire's su rface. The tire pressure is specified in
pounds per square inch (psi), in kilopascal (kPa)
or in bar. The tire pressure should only be cor rec‐
te d when the tires are cold.
Ti re pressure on cold tires: the tires are cold
when theve hicle has been par ked with the tires
out of direct sunlight for at least thre e hours and
th eve hicle has been driven less than 1 mile
(1.6 km).
Ti re contact sur face: the part of the tire that
comes into con tact wi th thero ad.
Ti re bead: the purpose of the tire bead is to
ensure that the tire sits securely on the wheel
ri m. There are se veral wire cores in the tire bead
to preve ntthe tire from changing length on the
wheel rim.
Side wall:the part of the tire between the tread
and the tire bead.
Special equipment weight: the combined
we ight of those optional extras that we igh more
th an there placed standard parts and more than
5 lbs (2.3 kg). These op tionalextras, su chas
high-pe rformance brakes, le vel control sy stem, a
ro of luggage rack or a high-per form ance batter y,
are not included in the curb weight and the
we ight of the accessories.
TIN (Tire Identification Number): a unique iden‐
tification number which can be used bya tire
manufacturer toidentify tires, forex ample for a
product recall, and thus identify the pur chasers.
The TIN is made up of the manufacturer identifi‐
cation code, tire size, tire type code and the man‐
ufacturing date.
Load-bearing index: the load-bearing index (also
load index) is a code that con tains the maximum
load-bearing capacity of a tire.
Tr action: traction is there sult of friction between
th e tires and thero ad sur face.
We ar indicator: narrow bars (tread wear bars)
th at are distributed overth e tire tread. If the tire
tread is le vel with the bars, thewe ar limit of
1/ 16 in (1.6 mm) has been reached.
Distribution of vehicle occupants: distribution
