2016 MERCEDES-BENZ GLC COUPE steering wheel

towards the edge of the carriageway, your vehi-
cle could come into contact with the kerb or
other road boundaries. Be particularly aware of
other road users, e.g. cyclists, that are directly
next to your vehicle.
Obstacles such as traffic pylons on the lane or
projecting out into the lane are not detected.
An inappropriate steering intervention, e.g. after
you have intentionally driven over a lane mark-
ing, can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS with Steering Assist and
Stop&Go Pilot cannot continuously keep your
vehicle in lane. In some cases, the steering
intervention is not sufficient to bring the vehicle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not
leave the lane.
The system may be impaired or may not function
in the following situations:
R poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road
surface is wet)
R the windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R no or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
R the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R the distance to the vehicle in front is so small
that the lane markings cannot be detected
R the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R the road is narrow and winding
R there are highly variable shade conditions on
the roadway
The system is switched to passive and no longer assists you by performing steering interventions
if:
R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
After you have finished changing lanes, Steering Assist and Stop&Go Pilot are automatically
active again. Steering Assist and Stop&Go Pilot cannot pro-
vide assistance in the following situations:
R on very sharp corners
R when a loss of tyre pressure or a defective
tyre has been detected and displayed
Also observe the important safety notes for
DISTRONIC PLUS (Y page 178).
The steering interventions are carried out with a
limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears on the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Assist
and Stop&Go Pilot switch to passive mode.
DISTRONIC PLUS remains activated.

Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting a parking
space. You may also use PARKTRONIC
(Y page 191).
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 objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
If you have attached a trailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between
your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk 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 obsta-
cles 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 In a zone where parking or stopping is pro-
hibited
R In front of driveways or entrances and exits
R On unsuitable surfaces
Parking tips:
R On narrow roads, drive as closely as possible
past the parking space
R Parking spaces that are littered or overgrown
might be identified or measured incorrectly
R Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly
R Snowfall or heavy rain may lead to a parking
space being measured inaccurately
R Pay attention to the PARKTRONIC
(Y page 192) warning messages during the
parking procedure
R You can intervene in the steering procedure
to correct it at any time. Active Parking Assist is then deactivated
R When transporting a load that protrudes from
your vehicle, you should not use Active Park-
ing Assist
R Never use Active Parking Assist when snow
chains are fitted
R Always pay attention to the specified tyre
pressure for your vehicle. This has a direct
influence on the parking characteristics of the vehicle
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Objects located above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken into account when the parking procedure is cal-culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles. 194

WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
Further information on the detection range
(Y page 191).
Active Parking Assist does not assist you with
parking in spaces at right angles to the direction
of travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward-park
Active Parking Assist does not assist you with
parking in spaces that are parallel or at right
angles to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, such as by foliage or grass paving
blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer :
Detected parking space on the left
; Parking symbol
= Detected parking space on the right Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle.
Active Parking Assist will detect only parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle
i Note that Active Parking Assist cannot
measure the size of a parking 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 ;as a status indicator in
the instrument cluster. When a parking space
has been detected, an arrow towards the right or
the left also appears. Active Parking Assist dis-
plays only parking spaces on the front-
passenger side as standard. 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 until you confirm the use of
Active Parking Assist by pressing the abut-
ton on the multifunction steering wheel. The
system automatically determines whether the
parking space is parallel or at right angles to the
direction of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 15 m away from it. Driving systems

Parking tips:
R The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front of and
behind it and the conditions of the location. It may be the case that Active Parking Assist
guides you too far into a parking space, or not
far enough into it. In some cases, it may also
lead you across or onto the kerb. If necessary,
you should cancel the parking procedure with Active Parking Assist.
R You can also preselect transmission position
D. The vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early, the park- 196
Driving systemsDriving and parking

ing procedure will be cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order that Active Parking Assist can support
you when you are exiting a parking space:
R the border of the parking space must be high
enough at the front and the rear. A kerb, for
example, is too small.
R the border of the parking space must not be
too wide. Your vehicle can be manoeuvred
into the parking space at a maximum angle of
45° to the starting position.
R a manoeuvring distance of at least 1.0 mmust
be available.
Active Parking Assist can assist you with exiting
a parking space as well only if you have parked
the vehicle parallel to the direction of travel
using Active Parking Assist.
i If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the vehicle is exiting the parking space. You are
responsible for braking in good time.
X Start the engine.
X Release the electric parking brake.
X Switch on the turn signal in the direction in
which you intend to pull away.
