2018 MERCEDES-BENZ GLC trailer

Steering Pilot cannot provide assistance: R
on very sharp corners R
when towing a trailer R
when a loss of tire pressure or a defective tire
has been detected and displayed
Pay attention also to the important safety notes
on Distance Pilot DISTRONIC ( Y
page 171).
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 in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel, a warning tone also
sounds to remind you to take control of the
vehicle after five seconds at the latest. Steering
Pilot is then switched to passive. Distance Pilot
DISTRONIC remains active.

RACE START
Important safety notes
i RACE START is only available for the
Mercedes-AMG GLC 63 4MATIC+ and
Mercedes-AMG GLC 63 S 4MATIC+ models.
i RACE START must not be used on normal
roads. RACE START must only be activated and used on dedicated road circuits, outside
of public road use.
i RACE START is only available after the vehi-
cle has been run-in ( Y
page 135).
RACE START enables optimal acceleration from
a standing start. For this, a suitably high-grip
road surface is required and the vehicle and tires
must be in good working order.
G WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an
accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
i Observe the safety notes on driving safety
systems ( Y
page 66).
Be sure to read the safety notes and informa-
tion on ESP ®
( Y
page 69).
Activation conditions You can activate RACE START if: R
the doors are closed R
the hood is closed R
the tailgate is closed R
the engine is running and the engine and
transmission are at operating temperature R
the steering wheel is in the straight-ahead
position. R
the vehicle is on a level surface R
the vehicle is stationary, the brake pedal is
depressed (left foot) and the parking brake is
released R
the transmission is in position [R

Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. You
can also still use Parking Assist PARKTRONIC
( Y
page 191).
Important safety notes Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Make sure that no persons, animals or
objects are in the path of your vehicle.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
For vehicles with a trailer tow hitch installed, the
minimum length for parking spaces is slightly
longer.
If you have attached a trailer to your vehicle, you
should not use Parking Pilot. Once the electrical
connection is established between your vehicle
and the trailer, Parking Pilot is no longer availa-
ble. Parking Assist 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
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot
parking procedure.
! If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces Parking tips: R
On narrow roads, drive as close to the parking
space as possible. 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 warning messages of
Parking Assist PARKTRONIC during the park-
ing procedure ( Y
page 193).R
You can intervene in the steering procedure
to correct it at any time. Parking Pilot is then
canceled- R
When transporting a load that protrudes from
your vehicle, you should not use Parking Pilot- R
Never use Parking Pilot when snow chains are
mounted. R
Always pay attention to the specified tire
pressure for your vehicle. This has a direct
influence on the parking characteristics of the
vehicle.
Use Parking Pilot 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 detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, tail sections or load-
ing ramps of trucks. Parking Pilot may therefore
guide you into the parking space too early.
G WARNING
If there are objects above the detection range: R
Parking Pilot may steer in too early R
the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.188

Further information about the detection range
( Y
page 192).
Parking Pilot does not assist you parking in
spaces at a right angle 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 curb R
you forward-park
Parking Pilot does not assist you parking in
spaces parallel with or at a right angle to the
direction of travel if: R
the parking space is on a curb R
the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks R
the area is too small for the vehicle to maneu-
ver into R
the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer

are no persons, animals or objects in the maneu-
vering area while maneuvering and parking in/
leaving parking spaces.
! When parking, pay particular attention to
objects above 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
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a truck or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
! If you do not need the trailer tow hitch,
remove the detachable ball coupling. Parking
Assist PARKTRONIC measures the minimum
detection range to an obstacle from the
bumper, not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you: R
switch on the ignition R
shift the transmission to position [ , ^ or
\\
Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/ h) . It is reactiva-
ted at lower speeds.
Parking Assist PARKTRONIC is deactivated for
the rear area when you establish an electrical
connection between your vehicle and a trailer.
Range of the sensors Parking Assist PARKTRONIC does not take into
account obstacles located: R
below the detection range, such as persons,
animals or objects R

loads, tail sections or loading ramps of trucks C

if the rear of your vehicle is damaged. In this
case, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the rear
view camera may be restricted due to additional
accessories on the rear of the vehicle (e.g.
license plate holder, rear bicycle rack).
The rear view camera is protected from rain-
drops and dust by means of a flap. When the rear
view camera is activated, this flap opens.
The flap closes again when: R
you have finished the maneuvering process R
you switch off the engine R
you open the cargo compartment
Observe the notes on cleaning ( Y

For technical reasons, the flap may remain open
briefly after the rear view camera has been
deactivated.
