When opening and raising the roof, automatic
operation is only available if the sliding sunroof
is in the closed position.
The sun protection cover automatically opens
along with the sliding sunroof. You can open or
close the sun protection cover manually when
the sliding sunroof is raised or closed.
You can continue to operate the sliding sunroof
after switching off the engine or removing the
SmartKey from the ignition lock. This function isavailable for up to five minutes or until the driv-
er's or front-passenger door is opened.
Resetting
!If the sliding sunroof still cannot be opened
or closed fully after resetting, contact a quali- fied specialist workshop.
Reset the sliding sunroof if it does not move
smoothly.
XTurn the SmartKey to position 1or 2in the
ignition lock.
XRaise the sliding sunroof fully at the rear
(Ypage 99).
XKeep the 3switch pressed for another
second.
XMake sure that the sliding sunroof can be fully
opened and closed again (Ypage 99).
XIf this is not the case, repeat the steps above.

power tilt/sliding panel
Opening and closing

;To open
=To close/lower
The panorama roof with power tilt/sliding panel
can only be operated when the roller sunblind is
open.
XTurn the SmartKey to position 1or 2in the
ignition lock.
XPress or pull the 3switch in the corre-
sponding direction.
If you press or pull the 3switch beyond the
point of resistance, automatic operation is star-
ted in the corresponding direction. You can stop
automatic operation by pressing or pulling
again.
If the panorama roof with power tilt/sliding
panel is raised at the rear, it automatically low-
ers slightly at higher speeds. The noise level in
the vehicle interior is reduced as a result. At low
speeds it raises again automatically.
You can also temporarily deactivate automatic
lowering. To do so, press the 3switch. The
panorama roof with power tilt/sliding panel rai-
ses again automatically.
You can continue to operate the panorama roof
with power tilt/sliding panel after you switch off the engine or remove the SmartKey. This func-
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 pano rama r
oof with
power tilt/sliding panel makes contact with a

XFold out lower plate;.
XGuide the lugs on the lower plate fully into the

XPlace chocks or other suitable items under
the front and rear of the wheel that is diago-
nally opposite the wheel you wish to change.
Raising the vehicle
GWARNING
If you do not position the jack correctly at the
appropriate jacking point of the vehicle, the
jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
!The jack is designed exclusively for jacking
up the vehicle at the jacking points. Other-
wise, your vehicle could be damaged.
Observe the following when raising the vehi-
cle:
RTo raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If used incorrectly, the
jack could tip over with the vehicle raised.
RThe jack is designed only to raise and hold the
vehicle for a short time while a wheel is being
changed. It must not be used for performing
maintenance work under the vehicle.
RAvoid changing the wheel on uphill and down- hill slopes.
RBefore raising the vehicle, secure it from roll-
ing away by applying the parking brake and inserting wheel chocks. Do not disengage the
parking brake while the vehicle is raised.
RThe jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a large,
flat, load-bearing underlay must be used. On a
slippery surface, a non-slip underlay must be
used, e.g. rubber mats.
RDo not use wooden blocks or similar objects
as
a jack underlay. Otherwise, the jack will not
be able to achieve its load-bearing capacity
due to the restricted height.
RMake sure that the distance between the
underside of the tires and the ground does not
exceed 1.2 in (3 cm).
RNever place your hands and feet under the
raised vehicle.
RDo not lie under the vehicle.
RDo not start the engine when the vehicle is
raised.
RDo not open or close a door or the trunk lid
when the vehicle is raised.
RMake sure that no persons are present in the
vehicle when the vehicle is raised.
Vehicles with alloy wheels and hub caps: the
wheel bolts are covered by a hub cap. Before you
can unscrew the wheel bolts, you must remove
the hub cap. Two different variants can be instal- led.
Vehicles with plastic hub cap:
XTo remove: turn the center cover of hub
cap :counter-clockwise and remove.
XTo install: before installing, ensure that hub
cap :is in the open position. To do this, turn
the center cover counter-clockwise.
XPosition hub cap :and turn the center cover
clockwise until hub cap :engages physically
and audibly.
XMake sure that hub cap :is installed
securely.

Brake fluid
GWARNIN G
The brak efluid constantl yabsorbs moisture
from th eair. This lower sth eboiling poin tof
th ebrak efluid .If th eboiling poin tof th ebrak e
fluid is to olow, vapo rpockets may for min th e
brak esystem when th ebrakes are applie d
hard. This would impair braking efficiency.
There is aris kof an accident.
You should hav eth ebrak efluid renewed at
th especifie dintervals.
When handlin gbrak efluid ,observ eth eimpor-
tan tsafet ynote son servic eproducts
(
Ypage 388).
The brak efluid chang eintervals can be foun din
th eMaintenance Booklet .
Only use brak efluid approve dby Mercedes-
Benz in accordanc ewit hMB-Freigabe or MB -
Approval 331.0.
Information about approve dbrak efluid can be
obtained at any qualified specialis tworkshop or
on th eInternet at
http://bevo.mercedes-benz.co m.
iHave the brake fluid regularly replaced at a
qualified specialist workshop in accordance
with the replacement intervals and the
replacement confirmed in the Maintenance
Booklet.
Coolant
Important safety notes
GWARNING
If antifreeze comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clean the
antifreeze from components before starting
the engine.
!Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact a qualified specialist workshop.
!Always use a suitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosion and
overheating.
iHave the coolant regularly replaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
(
Ypage 388).
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the fol-
lowing tasks:
Rcorrosion protection
Rantifreeze protection
Rraising the boiling point
If the coolant has antifreeze protection down to
-35 ‡ (-37 †), the boiling point of the coolant
during operation is approximately 266 ‡
(130 †).
The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
Rbe at least 50%. This will protect the engine
cooling system against freezing down to
approximately -35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection down
to -49 ‡ [-45 †]). Otherwise, heat will not be dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibito r concentra
te in accordance
with MB Specifications for Service Products
310.1.
iWhen the vehicle is first delivered, it is filled
with a coolant mixture that ensures adequate
antifreeze and corrosion protection.
