2019 MERCEDES-BENZ S-CLASS CABRIOLET brakes

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 appr oved.
Maximum permissible tire pressure: maxi‐
mum 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 of one axle bytwo.
PSI (pounds per square in ch):standard unit of
measurement for tire pressu re.
Aspect ratio: ratio between tire height and tire
width in pe rcent.
Ti re pressure: pressure inside the tire applying
an outward forc eto eve rysquare inch of the tire.
The tire pressure is specified in pounds per
square inch (psi), in kilopascals (kPa) or in bar.
The tire pressure should only be cor rected when
th e tires are cold.
Cold tire pressure: the tires are cold when the
ve hicle has been par kedfo r at least 3 hours without direct sunlight on
the tires or theve hicle
has been driven for 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.
We ight of optional equipment: the combined
we ight of the optional equipment weighing more
th an there placed standard parts and more than
5 lbs (2.3 kg).This optional equipment, such as
high-per form ance brakes, le vel control sy stem, a
ro of luggage rack or high-per form ance bat teries,
is not included in the curb weight and thewe ight
of the accessories.
TIN (Tire Identification Number): a unique
identification number which can be used by a
tire manufactu rerto identify tires, forex ample,
in a product recall, and thus identify the pur‐
ch asers. The TIN is made up of the manufactur‐ er's identity code, tire size, tire type code and
th e manufacturing date.
Load-bearing index: the load-bearing index is a
code that con tains the maximum load-bearing
capacity of a tire.
Tr action: traction is the grip resulting from fric‐
tion between the tires and thero ad sur face.
We ar indicator: narrow bars (tread wear bars)
th at are distributed overth e tire conta ct surface.
If th e tire tread is le vel with the bars, thewe ar
limit of 1/ 16in (1.6 mm) has been reached.
Distribution of vehicle occupants: distribution
of vehicle occupants over designated seat posi‐
tions in a vehicle.
Maximum permissible pa yload weight: nomi‐
nal load and luggage load plus 150 lb (68 kg)
multiplied bythe number of seats in theve hicle. Wheels and tires

R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(run-flat tire only for cer tain wheels)

tain AMG tires)
Cer tain characteristics, such as handling,
ve hicle noise emissions, fuel consum ption,
et c. may otherwise be adversely af fected.
Fu rthermore, other tire sizes could result in
th e tires rubbing against the body and axle
components when loaded. This could result
in damage tothe tire or theve hicle. 396

Obser
vethefo llowing when selecting, ins talling
and replacing tires:
R Only use tires and wheels of the same type
(summer tires, winter tires, MOEx tended
tires) and the same make.
R Only ins tall wheels of the same size on one
axle (left and right).
It is only permissible toins tall a dif fere nt
wheel size in theeve nt of a flat tire in order
to drive tothe specialist workshop.
R Only ins tall tires of the cor rect size onto the
wheels.
R Vehicles with a tire pressure monitoring
sy stem: All ins talled wheels must be equip‐
ped with functioning sensors forth e tire
pressure monitoring sy stem.
R Attemp eratures below 45 °F (7 °C), use win‐
te r tires or all-season tires mar ked M+S for
all wheels.
Wi nter tires bearing the004D snowflake sym‐
bol in addition tothe M+S marking pr ovide
th e best possible grip in wintry road condi‐
tions. R
For M+S tires, only use tires with the same
tread.
R Obser vethe maximum permissible speed for
th e M+S tires ins talled.
If th is is below theve hicle's maximum speed,
th is must be indicated byan appropriate
label in the driver's field of vision.

R When replacing with tires that do not fea‐
ture run-flat characteristics: vehicles with
MOExtended tires are not equipped with a
TIREFIT kit at thefa ctor y.Equip theve hicle
with a TIREFIT kit af terre placing with tires
th at do not feature run-flat characteristics,
e.g. winter tires.

WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
tem
The brake fluid constantly absorbs moisture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va por poc kets may form inthe brake sy stem
when the brakes are applied hard.
This causes the braking ef fect to be
impaired. #
Have the brake fluid rene we d at the
specified inter vals. Ha
ve the brake fluid regularly replaced at a
qu alified specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0.
