Important safety notes G
WARNING
When the load surface moves up, your hands may become trapped on the frame of the
EASY-PACK trunk box. There is a risk of injury.
When the load surface moves up, make sure
that your hands are not within the sweep of
the load surface. If someone becomes trap-
ped, carefully push the center of the load sur-
face downward.
! When the EASY-PACK trunk box is pulled
out, no objects may be placed on the frame
of the box, nor should the frame be pushed from above. Otherwise, the box could be
damaged.
! Sharp-edged, pointed or fragile objects
can damage the EASY-PACK trunk box and
then be thrown out. There is a risk of injury.
Do not transport sharp-edged, pointed or
fragile objects in the EASY-PACK trunk box. Always store and secure these or similar
objects in the trunk outside of the EASY-
PACK trunk box.
! If you exceed the maximum permitted
load of the EASY-PACK trunk box, objects
can be thrown out of the EASY-PACK trunk box and strike vehicle occupants. There is arisk of injury, particularly in the event of
sudden braking or a sudden change in
direction.
Always observe the maximum permitted
load of the EASY-PACK trunk box. Always
store and secure heavy objects in the trunk
outside of the EASY-PACK trunk box.
The maximum permitted load of the EASY-
PACK trunk box is 22 lb s(10 kg). With a load
of above approximately 11 lbs (5 kg), the bot-
tom of the box moves downward until it rests on the mat of the trunk floor. Thus, overload-
ing of the box is avoided. 304

Important safety notes G
WARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character- istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired. There is a risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
The maximum roof load can be found in the
"Technical data" (Y page 403).
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to avoid damage to the vehicle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain dam-
age even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is instal-
led you can:
R raise the sliding sunroof/panorama roof
with power tilt/sliding panel fully
R open the trunk lid fully
! To avoid damaging or scratching the cov-
ers, do not use metallic or hard objects to
open them. An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefore ensure that you observe
the roof carrier manufacturer's installation
instructions.
Vehicles with a panorama roof with
power tilt/sliding panel: the panorama roof
with power tilt/sliding panel cannot be
opened if a roof carrier is installed. The pan-
orama roof with power tilt/sliding panel can
still be raised to allow ventilation of the vehi-
cle 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.
Attaching the roof carrier X
Open covers 0043carefully in the direction of
the arrow.
X Fold covers 0043upwards.
X Only secure the roof carrier to the anchor-
age points under covers 0043.
X Observe the manufacturer's installation
instructions. Features

Cleaning the vehicle parts
Cleaning the wheels G
WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! Do not park the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked.
Cleaning the windows G
WARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol- vents to clean the inside of the windows. Do
not touch the insides of the windows with
hard objects, e.g. an ice scraper or ring.
There is otherwise a risk of damaging the
windows. !
Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away. This
can lead to corrosion damage and damage to electronic components.
X Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
product that is recommended and
approved by Mercedes-Benz.
Cleaning wiper blades G
WARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
! Do not pull the wiper blade. Otherwise,
the wiper blade could be damaged.
! Do not clean wiper blades too often and
do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
! Hold the wiper arm securely when folding
back. The windshield could be damaged if
the wiper arm smacks against it suddenly.
X Fold the windshield wiper arms away from
the windshield.
X Carefully clean the wiper blades with a
damp cloth.
X Fold the windshield wiper arms back again
before switching on the ignition.
Cleaning the exterior lighting !
Only use cleaning agents or cleaning
cloths which are suitable for plastic light
lenses. Unsuitable cleaning agents or
cleaning cloths could scratch or damage
the plastic light lenses. Care
