2018 MERCEDES-BENZ GLC lock

G WARNING
At high speeds the raised sliding sunroof auto-
matically lowers slightly at the rear. This could
trap you or other persons. There is a risk of
injury. Make sure that nobody reaches into
the sweep of the sliding sunroof whilst the
vehicle is in motion.
If somebody becomes trapped, immediately
pull back the sliding sunroof switch. The slid-
ing sunroof lifts during opening.
! Only open the sliding sunroof if it is free of
snow and ice. Otherwise, malfunctions may
occur.
Do not allow anything to protrude from the
sliding sunroof. Otherwise, the seals could be
damaged.
! The weather can change abruptly. It could
start to rain or snow. Make sure that the slid-
ing sunroof is closed when you leave the vehi-
cle. The vehicle electronics can be damaged if
water enters the vehicle interior.
Resonance noises can occur in addition to the
usual airflow noises when the sliding sunroof is
open. They are caused by minor pressure fluc-
tuations in the vehicle interior. Change the posi-
tion of the sliding sunroof or open a side window
slightly to reduce or eliminate these noises.
Sliding sunroof reversing feature In the following section, the term "sliding sun-
roof" refers to the panorama roof with power
tilt/sliding panel.
The sliding sunroof is equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts the sliding sunroof during the closing
process, the sliding sunroof opens again auto-
matically. The automatic reversing feature is
only an aid and is no substitute for your attention
when closing the sliding roof.
G WARNING
The reversing feature does not react: R
to soft, light and thin objects, e.g. small fin-
gers R
over the last 1/6 in (4 mm) of the closing
movement R
during resetting R
when closing the sliding sunroof again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure.
If somebody becomes trapped: R
release the switch immediately, or R
press the switch in any direction during the
automatic closing process
The closing process is stopped.

tion remains active for five minutes or until you
open a front door.
When a roof carrier is mounted the panorama
roof with power tilt/sliding panel cannot be
opened. The panorama roof with power tilt/slid-
ing panel can still be raised to allow ventilation
of the vehicle interior. If the panorama roof with
power tilt/sliding panel makes contact with a
roof carrier approved by Mercedes-Benz, the
sunroof will lower slightly but remain raised at
the rear.
Rain-closing feature The raised panorama roof with power tilt/sliding
panel automatically lowers when driving if it
starts to rain. The sliding sunroof is lowered
depending on: R
the road speed R
the intensity of the rain
You can manually cancel the automatic closing
procedure. Press or pull the W switch in any
direction.
To raise the panorama roof with power tilt/slid-
ing panel again, press the W switch in direc-

Important safety notes
G WARNING
Parts of the body could become trapped
between the roller sunblind and frame or slid-
ing sunroof during automatic opening or clos-
ing. There is a risk of injury.
When opening or closing, make sure that no
body parts are in the sweep of the roller sun-
blind.
If somebody becomes trapped: R
release the switch immediately, or R
during automatic operation, push the
switch briefly in any direction
The opening or closing procedure will be stop-
ped.
The roller sunblinds shield the vehicle interior
from sunlight. The roller sunblinds can only be
opened and closed when the panorama roof
with power tilt/sliding panel is closed.
Roller sunblind reversing feature The roller sunblinds are equipped with an auto-
matic reversing feature. If a solid object blocks
or restricts a roller sunblind during the closing
process, the roller sunblind opens again auto-
matically. However, the automatic reversing
feature is only an aid and is not a substitute of
your attentiveness when closing the roller sun-
blind.
G WARNING
The reversing feature does not react in par-
ticular to soft, light and thin objects, e.g. small
fingers. This means that the reversing feature
cannot prevent someone being trapped in
these situations. There is a risk of injury.
When closing the roller sunblind, make sure
that no body parts are in the sweep area.96

G WARNING
If you close the sliding sunroof again immediately after it has been blocked or reset, the sliding
sunroof closes with increased or maximum force. The reversing feature is then not active. Parts
of the body could be trapped in the closing area in the process. This poses an increased risk of
injury or even fatal injury.
Make sure that no parts of the body are in the closing area.
If somebody becomes trapped: R
release the switch immediately, or R
press the switch in any direction during the automatic closing process
The closing process is stopped.
! If the sliding sunroof still cannot be opened or closed as a result of a malfunction, contact a
qualified specialist workshop.

Problems with the seat heating / seat ventilation Problem
Possible causes/consequences and P Solutions
The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on. The on-board voltage is too low because too many electrical consum-
ers are switched on. X
Switch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation can be switched back on manually.104
