roof.
In a vehicle rollover, occupants not wearing
their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury

erly as entire body parts or portions of them
may protrude from the passenger compart-
ment.

accident and/or serious personal injury.!To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(

can sometimes change rapidly. Make sure to
close the tilt/sliding sunroof when leaving the

vehicle electronics could be damaged which is
not covered by the Mercedes-Benz Limited
Warranty.
iWhen the tilt/sliding sunroof is open, reso-
nance noises may result in addition to the usual

Warning!G
Make sure that no one is near the wheel
housing or under the vehicle when you lower
the vehicle while it is standing still. Limbs
could become wedged into or under the ve-
hicle.
For safety reasons, the vehicle can only be
lowered with all doors and the tailgate
closed. Lowering is interrupted if a door or
the tailgate is opened and will continue after
the door is closed again.
Warning!G
Please be aware that by raising the vehicle
level, the center of gravity also rises. There-
fore, always ensure that the vehicle level is
as low as possible. With higher ride height
the ESP
® may activate earlier in certain
situations.
Adapt your speed and driving to possible
changed driving behavior of the vehicle after
changing the vehicle level. The ESP
® cannot
prevent accidents, including those resulting
from excessive speed. The ESP
® cannot pre-
vent the natural laws of physics from acting
on the vehicle.
!Keep in mind that in rough or uneven ter-
rain, adjusting the vehicle to a lower level may
cause the vehicle underbody to come in contact
with the ground and result in damage to the vehi-
cle underbody. Always make sure the vehicle has
sufficient ground clearance before adjusting it to
a lower level.
!Before jacking up the vehicle with equip-
ment that lifts one or more of the wheels com-
pletely off of the ground, remove the SmartKey
from the starter switch.
!Please also note the information in the sec-
tion on towing (
