Parking Assist PARKTRONIC
Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitor st he area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not ar eplacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting ap arking space. Make sure that there
are no persons, animals or object sint he maneu-
vering area while maneuvering and parking in/
leaving parking spaces.
! When parking, pay particular attention to
object sa bove or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
object st hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of at ruck or
ap neumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you: R
switch on the ignition R
shift the transmission to position [ , ^ or
\\ R
release the electric parking brake Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva-
ted at lower speeds.
Range of the sensors General notes Parking Assist PARKTRONIC does not take into
account obstacles located: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, tail section sorl oading ramps of trucks.
C
Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean

If at ire pressure of 200 kPa (2.0 bar/29 psi) has
been attained after ten minutes: X
Switch off the tire inflation compressor. X
Unscrew the fille rh ose from the valve of the
faulty tire.
Note that tire sealant may escape when you
unscrew the fille rh ose.X
USA only: Stow the tire sealant bottle and the
tire inflation compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for as hort period ,t he tire is too
badl yd amaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.

Whee la nd tire combinations
General notes You can ask for information regarding permitted
wheel/tire combinations at an authorized
Mercedes-Benz Center.
You should regularl yc heck the pressure of the
emergency spare wheel, particularly prio rt o
long trips, and correct the pressure as neces-
sary ( Y
pag e2 90). The valu eont he wheel is
valid.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tires and wheels
which have been approved by Mercedes-Benz
specifically for you rv ehicle.
These tires have been speciall ya dapted for
use with the control systems, such as ABS or
ESP ®
,a nd are marked as follows:R
MO = M ercedes-Benz OriginalR
MOE = M ercedes-Benz Original Extended
(tires featuring run-fla tc haracteristics)R
MO1 = M ercedes-Benz Original (only cer-
tain AMG tires)
Mercedes-Benz Original Extended tires may
only be use donw heels that have been spe-
cifically approved by Mercedes-Benz.
Only use tires, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicl en oise
emissions or fuel consumption, may other-
wis ebea dversely affected .Ina ddition, when
driving with al oad, tire dimension variations
coul dc aus et he tires to come into contact
with the bodywork and axle components. This
coul dr esult in damage to the tires or the vehi-
cle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tires, wheels or
accessories other than those tested and
approved.
Informatio nont ires, wheels and approved
combinations can be obtained from any quali-
fied specialist workshop.
! Retreaded tires are neither tested nor rec-
ommende dbyM ercedes-Benz, since previ-
ous damage cannot alway sbed etected on
retreaded tires. As ar esult, Mercedes-Benz
cannot guarantee vehicl es afety if retreaded
tires are mounted .Don ot mount use dt ires if
you have no information abo ut thei r previous
u
sage. The recommende dp ressures for various oper-
ating conditions can be found: R
on the Tire and Loading Informatio np lacard
on the B-pillar on the driver's side R
in the tire pressure tabl eint he fuel filler flap
Observe the notes on recommende dt ire pres-
sure su nder various operating conditions
( Y
pag e2 90).
Check tire pressures regularly ,a nd only when
the tires are cold. Comply with the maintenance
recommendations of the tire manufacturer in
the vehicl ed ocument wallet.
Notes on the vehicl ee quipment –a lway se quip

Exception: it is permissible to instal lad iffer-
ent type or make in the event of af lat tire.
Observe the "MOExtended tires (tires with

Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory .I t
is therefore recommende dt hat you additionally
equip you rv ehicl ew ith aT IREFIT kit if you mount

Brake fluid
G WARNING
The brake flui dc onstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,v apo rp ockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is ar isk of an accident.
You should have the brake flui dr enewe da t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
( Y
pag e3 15).
The brake flui dc hange interval sc an be found in

Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clea nt he
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul do therwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aq ualified specialist workshop.
! Always use as uitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio na nd
overheating.
i Have the coolant regularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y
pag e3 15).
The coolant is am ixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks: R
Anti-corrosion protection R
Antifreeze protection R
Raising the boiling point
If the coolant has antifreeze protection down to
-35 ‡( -37 †), the boiling point of the coolant
during operation is approximatel y2 66 ‡
