PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park- ing space. When maneuvering, parking or
pulling out of a parking space, make sure that
there are no persons, animals or objects in
the area in which you are maneuvering.
!When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
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
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
General notes
PARKTRONIC does not take objects into con-
sideration that are:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps.
:Sensors in the front bumper, left-hand
side (example)
The sensors must be free from dirt, ice or
slush. They can otherwise not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them
(
Ypage 380).
224Driving systems
Driving and parking

Adaptive
WhenAdaptive
isselected, no warning vibra-
tion occurs if:
Ryou swit ch on the turn signals. Inthis event,
the warnings are suppressed for a certain
period of time.
Ra driv ing safety system intervenes, e.g.
AB S,BAS or ESP®.
Ryou accelerate hard, e.g. kickdown.
Ryou brake hard.
Ryou steer actively, e.g. swerve to avoid an
obstacle or change lanes quickly.
Ryou cut the corner on a sharp bend.
In order that you are warned only when nec-
essary and ingood time ifyou cross the lane
marking, the system recognizes certain con-
dit ions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou appr oach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a high-
way.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe road has narrow lanes.
Ryou cut the corner on a bend.
Active Driving Assistance package
General notes
The Active Dr iving Assistance package con-
sists of DI STRONIC PLUS (
Ypage 205), Acti ve
Blin dSpo t Assist (
Ypage 248) and Active
Lane Keepin g Assist (
Ypage 251).
Active Blind Spot Assist
General notes
ActiveBlindSpo t Assist mon itors the areas
on either sideof the vehicle that are not
dire ctly vis ible to the driver with two lateral,
rear-facing radar sensors. A warning lamp
lights up inthe exterior mirrors and draws your attention to vehicles detected
inthe
mon itored area. Ifyou then switch on the cor-
respondin g turn signal to change lanes, you
will also receive a visual and audible co llision
warning. Ifa risk of lateral co llisionis detec-
te d, correct ivebraking may help you avoid a
co llisio n. Before a course-correcting brake
applic ation, Acti veBlind Spot Assist evalu-
ates the space inthe dire ction of travel and at
the sides of the vehicle. For this, Acti veBlind
Spot Assist uses the forward-facing radar
sensors.
Acti veBlind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Imp ortant safety notes
Acti veBlind Spot Assist isonly an aid and is
not a substitute for attenti vedriving.

Driving and parking

Either no braking application, or a course-
correcting brake application adapted to the
driving situation occurs if:
Rthere are vehicles or obstacles, e.g. crash
barriers, close to both sides of your vehicle.
Ra vehicle approaches you too closely at the
side.
Ryou have adopted a sporty driving style with
high cornering speeds.
Ryou brake or accelerate significantly.
Ra driving safety system intervenes, e.g.
ESP®or PRE-SAFE®Brake.
RESP®is switched off.
Rthe off-road program is activated (vehicles
without the ON&OFFROAD package).
Roff-road program 1 or 2 is activated (vehi-
cles with the ON&OFFROAD package).
Rthe LOW RANGE off-road gear is activated
(vehicles with the ON&OFFROAD package).
Ra loss of tire pressure or a defective tire is
detected.
Switching on Active Blind Spot Assist
XMake sure that Active Blind Spot Assist is
activated in the on-board computer
(
Ypage 282).
XTurn the SmartKey to position 2in the igni-
tion lock.
Warning lamps :in the exterior mirrors
light up red for approximately 1.5 seconds
and then turn yellow.
Towing a trailer
When you attach a trailer, make sure y
ou have
correctly established the electrical connec-
tion. This can be accomplished by checking
the trailer lighting. Active Blind Spot Assist is
then deactivated. The indicator lamp lights up
yellow in the exterior mirrors and the Active
BlindSpotAssistCurrentlyUnavail‐
able See Operator's Manualmessage
appears in the multifunction display.
Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area
in front of your vehicle by means of camera :
at the top of the windshield. Active Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational
Important safety notes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of accident nor override the laws of phys-
ics. Active Lane Keeping Assist cannot take
into account road, weather or traffic condi-
tions. Active Lane Keeping Assist is only an
aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for
braking in good time and for staying in your
lane.
Active Lane Keeping Assist cannot continu-
ously keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
