Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING

Parking the vehicle for a long period
General notes
If you leave the vehicle parked for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked for longer than six
weeks, the vehicle may suffer damage as a
result of lack of use.
XVisit a qualified specialist workshop and seek
advice.
Trickle charging the on-board electrical
system battery
The battery may drain if the vehicle is left sta-
tionary for long periods. In this case, Mercedes-
Benz recommends attaching the trickle charger
to 12 V socket :in the cargo compartment.
iA trickle charger and further information
can be obtained from a qualified specialist
workshop.
XSwitch the ignition off.
XOpen the tailgate.

The tailgate can be closed, even ifa trick le
charger isconnected. Make sure that the con-

Important safety notes
GWAR NING
If you switch off the ignition while driving,
safety-relevant functions are only available
wit hlimit ations, or not at all.This could affect,
for example, the power steering and the brake
boosting effect. You willrequire cons iderably
more effort to steer and brake. There isa risk
of an acc ident.
Do not switch off the ignition while driving.
GWARNING
If you operate mob ilecommunication equip-
ment when driving, you may be distracted
from the traff icsituation. You could also lose
control of the veh icle. There isa risk of an
acc iden t.
Only operate th is equipment when the veh icle
is stationary.
Observe the legal requirements for the country
in whic h you are driving. Some jur isdictions pro-
hibit thedriver from using a mob ilephone while
driv ing a veh icle. If
you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traff icsituation permits. Ifyou are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear inmind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
dist ance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

Reversing camera
General notes
Rear view camera :is located in the rear
bumper, underneath the tailgate.
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind your
vehicle with guide lines in the multimedia sys-
tem display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
iThe text shown in the multimedia system
display depends on the language setting. The
following are examples of rear view camera
messages in the multimedia system display.
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering and parking. Make sure
that there are no persons, animals or objects
etc., in the maneuvering area while maneuvering
and parking in parking spaces.
The rear view camera will not function or will
function only to a limited extent if:
Rin heavy rain, snow or fog
Rat night or in very dark places
Rif the camera is exposed to very bright light
Rif the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
Rif there is a sudden change in temperature,

Loading guidelines
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
GWARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
!This vehicle is not designed to transport
items on the roof. Roof carriers and other
devices which are mounted on the roof that
have not been specifically approved for this
model by Mercedes-Benz must not be used as
they could damage the vehicle and the
retractable hardtop (vario-roof).
At the time of going to print, Mercedes-Benz
does not offer any roof carrier or other roof-
installed devices for this model.
!This vehicle is not designed for objects such
as luggage carriers or other devices to be
installed or transported on the trunk lid.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a load:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle iden-
tification plate on the B-pillar of the driver's
door.
RThe cargo compartment is the preferred place
to carry objects.
RPosition heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment as possible.
RThe load must not protrude above the upper
edge of the seat backrests.
RHook in the cargo net when loading.
RSecure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges forprotection.
Stowage spaces
Important safety notes
GWARNING
If you transport objects in the vehicle interior
and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of
an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction.
RAlways stow objects in such a way that they cannot be tossed about in these or similar
situations.
RAlways make sure that objects do not pro-
trude out of the stowage spaces, luggage
nets or stowage nets.
