Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead toaparking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 195) warning messages during the
parking procedure.
RYou can intervene in the steeringprocedure
to correctitatany time. Active Parking
Assist will then be canceled.
RWhen transportingaload which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
alwayscorrect. This hasadirectinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthatare paralleltothe direction of travel
Rthat are on straight roads, not bends
Rthat are on the same levelasthe road,e.g.
not on the pavement
Detectingparking spaces
Objects located above the height range of
Active Parking Assist willnot be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated,e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may causeacollision asaresult. There is
arisk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.

Active Parking Assist is switched on
automaticallywhen driving forwards. The
system is operational at speeds of up to
approximately 22 mph (35 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle.

Only winter tires bearing thesnowflake
symbol in addition to the M+S marking
provide the best possiblegrip in wintry road
conditions.
Only these tires will allowdriving safety
systems such as ABS and ESP®to function
optimally in winter. These tires have been
developedspecificallyfor driving in snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.
Alwaysobserve the maximum permissible
speed specified for the M+S tires you have
mounted.
Once the winter tires are mounted:
XCheck the tire pressures (Ypage 341).
XVehiclesfor Canada:restart the tire
pressure loss warning system
(Ypage 342).
XRestart the tire pressure monitor

Snow chains
GWARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There isarisk of an accident.
To avoid hazardous situations:
Rnever install snow chains to the front
wheels
Ralways install snow chains in pairs to the
rear wheels.
!On vehicles with AIRMATIC, you must
drive at raised vehicle level if snow chains
have been mounted. The vehicle may
otherwise be damaged.
!On some tire sizes there is not enough
space for snow chains. To avoid damage to
the vehicle or tires, observe the "Wheel and
tire combinations" section under "Tires and
wheels".
For safety reasons, Mercedes-Benz
recommends that you only use snow chains
that have been speciallyapproved for your
vehicle by Mercedes-Benz,orare of a
corresponding standard of quality.
If you intend to mount snow chains, please
bear the following points in mind:
RSnow chains may not be mounted on all
wheel/tire combinations. Permissible
wheel-tire combinations (Ypage 362).
ROnly use snow chains when driving on
roads completely covered by snow.
Remove the snow chains as soon as
possiblewhen you come toaroad that is
not snow-covered.
RLocal regulations may restrict the use of
snow chains. Observe the appropriate
regulations if you wish to mount snow
chains.
RDo not exceed the maximum permissible
speed of 30 mph (50 km/h).
iYou may wish to deactivate ESP®when
pulling away with snow chains installed
(Ypage 69). This way you can allow the
wheels to spin inacontrolled manner,
achieving an increased driving force
(cutting action).

Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
(Ypage 338).
Information on air pressure for the tires on
your vehicle can be found:
Ron the vehicle's Tire and Loading
Information placard on the B-pillar
(Ypage 345)
Ron the tire pressure label on the fuel filler
flap (Ypage 165)
Rin the "Tire pressure" section
Runder "Tire pressure" (Ypage 338)
Checking tire pressures manually
To determine and set the correct tire
pressure, proceed as follows:
XRemove the valve cap of the tire that is to
be checked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Ypage 338).
XIf the tire pressure is too low, increase it to
the recommended value.
XIf the tire pressure is too high, release air
by pressing down the metal pin in the valve.
Use the tip ofapen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
XScrew the valve cap onto the valve.
XRepeatthese steps for the other tires.
Tire pressureloss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss inatire. If the speed
of rotation ofawheel changes asaresult of
aloss of pressure,acorresponding warning
message will appearinthe multifunction
display.
You can recognizethe tire pressure loss
warning by theRun Flat Indicator
Active Press 'OK' to Restartmessage
which appears in theServ.menu of the
multifunction display. Further information on
the message displaycan be found under
"Restarting the tire pressure loss warning
system" section (Ypage 342).
Important safety notes
The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Ypage 338).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you ofasudden loss of pressure, e.g. if the
tire is penetrated byaforeign object.Inthe
event ofasudden loss of pressure, bring the
vehicle toahalt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditionsare wintry.
Ryou are driving on sand or gravel.
