Risk of injury
Children could injure themselves if they
operate the sliding/tilting sunroof.
Never leave children unsupervised in the
vehicle. Always take the KEYLESS–GO
key* with you when leaving the vehicle,
even if you are only leaving it for a short
time. G
Risk of injury
Make sure that nobody can become trap-
ped when you are opening and closing the
sliding/tilting sunroof. If there is a risk of
entrapment, release the switch and push it
briefly in any direction to stop the sliding/
tilting sunroof. G
Risk of injury
The glass in the sliding/tilting sunroof
could break in an accident. If you are not
wearing a seat belt, there is a risk that you
could be thrown through the opening in the
event of the vehicle overturning. Therefore,
always wear a seat belt to reduce the risk
of injuries. !
Only open the sliding/tilting sunroof if it
is free of snow and ice. Otherwise, mal-
functions may occur.
Do not allow anything to protrude from the
sliding/tilting sunroof. The seals could oth-
erwise be damaged.
i Resonance noises can occur in addition
to the usual airflow noises when the slid-
ing/tilting sunroof is open. They are caused
by minor pressure fluctuations in the vehi-
cle interior.
Change the position of the sliding/tilting
sunroof or open a side window slightly to
reduce or eliminate these noises.
i It is also possible to open and close the
sliding/tilting sunroof from the outside
using the "Summer opening" (Y page 101)
and "Convenience closing" (Y page 102)
features respectively.
When PRE-SAFE ®
* has been activated, the
sliding/tilting sunroof closes automatically in
the event of danger, leaving a small gap open. Controls

Loading and stowing
192 Loading guidelines
G
Risk of injury
Secure and position the load as described
in the loading guidelines.
Otherwise, vehicle occupants could
be injured by the load being thrown around
in the event of sharp braking, a sudden
change in direction or an accident. This also
applies to seats which have been removed.
You will find further information in the
"Securing a load" section.
Even if you follow all the loading guidelines,
the load will increase the risk of injury in the
event of an accident. G
Risk of poisoning
Keep the tailgate closed when the engine is
running. Otherwise, you could be poisoned
by exhaust fumes entering the vehicle.
The handling characteristics of a laden vehi-
cle depend on the distribution of the load
within the vehicle. You should therefore load
your vehicle as shown in the illustrations. Load distribution
Observe the following notes when transport-
ing a load:
R
When transporting a load, never exceed the
maximum permissible gross vehicle weight
or the permissible axle loads for the vehicle
(including occupants).
R Position heavy loads as far forwards and as
low down in the luggage compartment as
possible.
R The load must not protrude above the
upper edge of the backrests.
R Always place the load against the front or
rear seat backrests. Make sure that the backrests and the seats are securely
locked into place.
R Secure the load with sufficiently strong and
wear-resistant load restraints. Pad sharp
edges for protection.
i Load restraints are available at any quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre. R
If the rear seats are not occupied, insert the
belt tongue on the outer seat belts into the
buckle of the opposite seat belt. This
increases the restraining effect of the rear
seat backrests. Controls
