stem limitations of Active Parking Assist
Objects located abo veor below the de tection
ra nge of Active Parking Assist are not de tected
when the parking space is being measured.
These are also not take n into account when the
parking maneuver is calculated, e.g. overhanging
loads, overhangs or loading ramp s of truc

these 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 pressure .
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 pr
eve ntthe t
ire fromchanging 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 batte ries,
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 bya
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 ov
er design
ated 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.

TEDama getovehicle and tires due to
non-app rove d tire types and sizes
Fo r saf etyre asons, only use wheels, tires
and accessories which havebeen appr oved
fo ryo ur vehicle byMercedes-Benz.
These tires ha vebeen specially adap tedfo r
use with the control sy stems, e.g. ABS or
ESP
®, and are mar ked as follo ws :
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(run-flat tires only for cer tain wheels)
RMO1 = Mercedes-Benz Original (only cer‐
tain AMG tires)
Cer tain characteristics, e.g. handling, vehicle
noise emissions or fuel consum ption, may
ot herwise be adversely af fected. In addition,
when driving wi tha load, tire dimension var‐
iations could cause the tires tocome into
contact wi th the body and axle components.
This could result in damage tothe tires or the

Wheels and tires

Observethefo llowing when selecting, ins talling
and replacing tires:
ROnly use tires and wheels of the same type
(summer tires, winter tires, MOEx tended
tires) and the same make.
ROnly mount wheels of the same size on one
axle (left and right).
It is only permissible tomount a dif fere nt
wheel size in theeve nt of a flat tire in order
to drive tothe specialist workshop.
ROnly mount tires of the cor rect size onto the
wheels.
RVe hicles with a tire pressure monitoring
sy stem: All mounte d wheels must be equip‐
ped with functioning sensors forth e tire
pressure monitoring sy stem.
RAt temp 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 thei snowflake sym‐
bol in addition tothe M+S marking pr ovide
th e best possible grip in wintry road condi‐
tions.
RFo r M+S tires, only use tires with the same
tread.
RObser vethe maximum permissible speed for
th e M+S tires mounted.
If th is is below theve hicle's maximum speed,
th is must be indicated in an appropriate label
in the driver's field of vision.
RBreak in new tires at moderate speeds for

Notes on brake fluid
Obser vethe no tes on operating fluids
(→page 394).
& WARNING Risk of an accident due to
va por poc kets form ing in the brake sys‐
te m
The brake fluid cons tantly absorbs moist ure
from the air. This lo wersthe boiling point of
th e brake fluid. Ifth e 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.
#Ha ve the brake fluid rene we d at the
specified inter vals.
Ha ve the brake fluid regularly changed at a quali‐
fi ed specialist workshop.
Only use brake fluid appr ovedby Mercedes-Benz
according toMB-F reigabe or MB-Appr oval 33 1.0.
