WARNING
When you open the sliding door, the sliding
door could hit other people as it moves
backwards. There is a risk of injury.
Only open the sliding door when traffic con-
ditions permit.
! Do not use the lower sliding door guide
(carriage) as a step. Otherwise, you could
damage the paneling and/or the sliding
door mechanism.
You must reset the electric sliding door if
there has been a malfunction or an interrup-
tion in the voltage supply
(Y page 80).
i Please note, if the child-proof locks have
been activated, you cannot open the sliding
door from the inside. You can only open a
sliding door from the inside if the child-proof
locks have not been activated. Further infor-
mation can be found under "Child-proof
locks for the sliding door" (Y page 66) and
"Opening/closing from the inside"
(Y page 79). Obstacle detection with reversing
feature
The sliding door is equipped with automatic
obstacle detection with reversing feature. If a
solid object blocks or restricts the sliding door
during the automatic closing process, the slid-
ing door opens again automatically. If the slid-
ing door is obstructed during the opening pro- cedure, it moves back a few centimeters in the
opposite direction and stops.
Automatic obstacle detection with reversing
feature is only an aid. It is not a substitute for
your attentiveness when closing the electrical
sliding door.
If an obstacle is detected, the display shows
the Left-hand Electric Sliding Door
Obstruction Detected message for exam-
ple, and five warning tones sound. G
WARNING
The reversing feature does not react:
R to soft, light and thin objects, e.g. small
fingers
R over the last 8 mm of the closing move-
ment
This means that the reversing feature can-
not prevent someone being trapped in these
situations. There is a risk of injury.
When closing, make sure that no-one has
any parts of the body within the closing
area.
If someone is trapped:
R press the 5 button on the SmartKey,
or
R pull the exterior door handle, or
R press the corresponding sliding door but-
ton in the center console, or
R press the button on the door frame, or
R pull the rocker switch on door handle Opening/closing from the outside78

Consult a qualified specialist workshop which
has the necessary specialist knowledge and
tools to carry out the work required.

Important safety notes
G
DANGER
Combustion engines emit poisonous
exhaust gases, such as carbon monoxide.
Exhaust gases can enter the vehicle interior
if the rear-end door is open when the engine
is running, especially if the vehicle is in
motion. There is a risk of poisoning.
Always switch off the engine before opening
the rear-end door. Never drive with the rear-
end door open. G
WARNING
If you open a rear door, you could:
R endanger other people or road users
R be caught by oncoming traffic
This is particularly the case if you open the
rear door more than 90°. There is a risk of
an accident and injury.
Only open the rear doors when traffic condi-
tions permit. Always make sure that the rear
doors are properly locked. G
WARNING
If you open the rear-end doors 90°, the rear
lighting systems are no longer visible. The
vehicle will then be difficult for other road
users to see or will not be seen by them at
all, particularly if it is dark or visibility is
poor. There is a risk of an accident.
You should therefore ensure in this and simi-
lar situations that the vehicle is visible from
the rear in accordance with the relevant
national regulations, by using the warning
triangle, for instance.
! Make sure that there is sufficient clear-
ance when opening the rear doors. You
could otherwise damage the vehicle and
objects in close range of the rear doors.
You can lock the rear-end doors at an angle of
approx. 90° and, if necessary,
180° or 270°.
Always make sure that the open rear-end door
is correctly engaged in the detent. Opening and closing from the out-

To prevent damage to the seats and the
seat heating, observe the following notes:
R Do not spill liquids onto the seats. Dry the
seats as soon as possible if liquid does
get spilled on the seats.
R If the seat covers are damp or wet, do not
switch on the seat heating. Also, do not
use the seat heating to dry the seats.
R Clean the seat covers as recommended;
see the "Interior care" section.
R Do not transport heavy loads on the
seats. Do not place pointed objects on
the seat cushions such as knives, nails or
tools. Where possible, use the seats only
for carrying passengers.
R When operating the seat heating, do not
cover the seats with insulating materials,
e.g. blankets, coats, bags, protective cov-
ers, child seats or booster seats.
R When the seat heating is switched on, the
seat surface can be damaged as a result
of objects being placed on the seats, for
example, seat cushions, child seats and
protective covers not approved by
Mercedes-Benz.
Your seat must be adjusted in such a way that
you can wear the seat belt correctly.
Observe the following points:
R Position the backrest in an almost vertical
position so that you are sitting virtually
upright. Do not drive with the backrest
reclined too far back.
R Your arms should be slightly bent when you
are holding the steering wheel.
R Avoid seat positions that prevent the seat
belt from being correctly routed. The shoul-
der section of the belt must be routed over
the middle of your shoulder and be pulled
tight against your upper body. The lap belt
must always pass across your lap as low
down as possible, i.e. over your hip joints.
R Adjust the head restraint so that it supports
the back of the head at eye level.
R The distance from the pedals should be
such that you can depress them fully.
