Active Parking Assist
Fu nction of Active Parking Assist
Ac tive Parking Assist is an elect ronic pa rking
assis tance sy stem which uses ultrasound and is
automatically activated during forw ard tra vel.
The sy stem is operational at speeds of up to
appr oximately 22 mph (35 km/h). When all the
conditions are ful filled, thec symbol appears
in the multifunction display and the sy stem auto‐
matically sear ches for and measu res parking
spaces on bo thsides of theve hicle parallel and
perpendicular tothe direction of tra vel. If Active
Pa rking Assist is activated, suitable parking
spaces are displa yed in the multimedia sy stem. The
ë symbol appears in the multifunction
displa y.The ar rowsshow on which side of the
car riag ewa yfree parking spaces ar elocated.
The parking spac eand ,if necessar y,the parking
direction can be selected as desired. Active
Pa rking Assist calculates a suitable vehicle path
and assists youin parking and exiting the park‐
ing space.
Ac tive Parking Assist changes gear, accelerates,
brakes and steers theve hicle.
Ac tive Parking Assist is only an aid. It is not a
substitute foryo ur attention tothe sur roundings.
The responsibility for safe maneu vering and
pa rking remains with you. Make sure that no
persons, animals or objects etc. are in the
ma

neu vering range.
Ac tive Parking Assist is canceled if, among other
th ings, one of thefo llowing actions is car ried
out:
RYo u deactivate Parking Assist PARKTRONIC.
RYou deactivate Active Parking Assist.
RYo u begin steering.
RYo uappl yth e parking brake.
RYo u enga ge005D.
RESP®inter venes.
RYo u open theta ilgate.
Sy 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 ksor
th e boundaries of parking spaces. In some cir‐
cums tances, Active Parking Assist may therefore
guide you into the parking space prematurel y.

Ve hicles with Blind Spot Assis t:Dr ivers can
also be warned of any crossing traf fic when
back ing out of a parking space. If a critical situa‐
tion is de tected, a warning symbol appears on
th e camera image of the multimedia sy stem. If
th e driver does not respond tothewa rning, the
ve hicle's brakes can be applied automaticall y.To
do this, the function uses thera dar sensors in
th e bumper. The area adjacent totheve hicle is
continually monitored.
If th era dar sensors are obstructed byvehicles
or other objects, de tection is not possible.

If AT TENTION ASSIST de tects indicators of fati‐
gue or increasing lapses in concentration on the
part of the driver, it suggests taking a brea k.
AT TENTION ASSIST is only an aid. It cann ot
alw ays de tect fatigue or lapses in concentration

fo r ade quate recuperation.
Yo u can choose between two settings.
RStandard: normal sy stem sensitivity
RSensitive: higher system sensitivity. The
driver is warned earlier and the attention

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 ha vebeen 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
ve hicle.

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 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.
ROnly ins tall 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 the004D snowflake sym‐
bol in addition tothe M+S marking pr ovide

RFo r M+S tires, only use tires with the same
tread.
RObser 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 in an appropriate label
in the driver's field of vision.
RRu n in new tires at moderate speeds forth e

RRe place the tires af ter six years at the latest,
re ga rdless of wear.
RWhen 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,

0071 WARNING Risk of an accident due to

te m
The brake fluid constantly absorbs moisture
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.
