The vehicle can compensate differences in

ldrive)
If you fai ltoadapt you rdriving style, 4MATIC
can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot
take account of road ,weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsibl efor the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If ad rive wheel spins due to insufficient grip:
R whe npulling away,o nly depress the accel-
erato rpedal as far as is necessary.
R accelerate les swhend riving.
! Never tow the vehicle with one axle
raised. Thi smay damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain eithe ronthe ground or
be fully raised. Observe the instructions for towing the vehicle with allw heels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you use winter tyres
(M+S tyres), with snow
chains if necessary.
4MATIC ensures that allf our wheels are per-
manently driven. Together with ESP ®
,it
improves the traction of you rvehicle when-
ever adrive wheel spins due to insufficient
grip. PARKTRONIC

General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. Aparking symbol
indicates asuitable parking space. Active
steering intervention and brake application
can assist you during parking. You may also
use PARKTRONIC (Y page 235).
i The active braking application is only
available on vehicles with automatic trans- mission.
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or
objectsa re in the manoeuvring range. When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at a
sharp angle. Otherwise, you may damage
the wheels or tyres.
Active Parking Assist may also display spaces not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of drivewaysore ntrances and exits
R unsuitable surfaces Driving systems

Activ
eParking Assist is activated automati-
cally when driving forwards .The system is
operational at speeds of up to approximately 35 km/h .While in operation, the system inde-
pendently locate sand measures parking
space sonb oths ides of the vehicle.
Activ eParking Assist will onl ydetect parking
spaces:
R parallel or at right angle stothe direction of
travel.
R tha tare parallel to the direction of travel
and ar eatleast1.5mw ide
R that are parallel to the direction of travel
and at leas t1.0ml onger than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your
vehicle
i Note that Active Parking Assist cannot
measure the size of aparking space if it is at
right angles to the direction of travel. You
will need to judge whether your vehicle will
fit in the parking space.
When driving at speeds below 30 km/h, you
will see parking symbol ;asas tatus indi-
cator in the instrument cluster. When apark-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only display sparking
spaces on the front-passenger side as stand- ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. When parking on the driver's side, this must remain activated untilyou confirm the use of Active Parking Assist
by pressing the abutton on the multi-
function steerin gwheel. The system auto-
matically determines whether the parking
space is parallel or at right angles to the direc-
tion of travel.
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 maway from it. Parking G
WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
R there is amalfunction in the system or in
the voltage supply.
R the electrical system in the engine com-
partment ,the battery or the fuses are tam-
pered with.
R the battery is disconnected.
R the vehicle is accelerated, e.g. by avehicle
occupant.
There is arisk of an accident.
Before leaving the vehicle, alwayss ecure it
against rolling away.
i Vehicles with automatic transmission:
When PARKTRONIC detect sobstacles,
Active Parking Assist brakes automatically
during the parking process. You are respon-
sible for braking in good time.
X Stop the vehicle when the parking symbol
shows the desired parking space in the
