WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the boot
lid is open when the engine is running, espe-
cially if the vehicle is in motion. There is arisk
of poisoning.
Always switch off the engine before opening
the boot lid. Never drive with the boot lid
open. G
WARNING
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 arisk of injury, especially
when braking or abruptly changing directions.
Always store objectssot hat they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
WARNING
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 arisk 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.
The handling characteristics of aladen 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:
R never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the boot is the preferred place to store
objects.
R position heavy loads as far forward as possi-
ble and as low down in the boot as possible. R
the load must not protrude above the upper
edge of the seat backrests.
R always place the load behind unoccupied
seats if possible.
R secure the load with sufficiently stronga nd
wear-resistant lashing material. Pad sharp
edges for protection.

of injury, particularly in the event of sudden
braking or asudden change in direction.
R Always stow objectssot hat they cannot be

Important safety notes G
WARNING
When aload is transported on the roof, the
vehicle's centre of gravity rises and the han-
dling changes. If you exceed the maximum
roof load, the handling as well as steering and braking characteristics are severely affected.
There is arisk of an accident.
Always observe the maximum roof load and
adapt your driving style.
You will find information on the maximum roof
load in the "Technical data" section
(Y page 377). !
Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz vehicles. This
helps to prevent damage to the vehicle.
Position the load on the roof carrier in such a way that the vehicle will not sustain damage
even when it is in motion.
Depending on the vehicle equipment, ensure
that when the roof carrier is fitted you can:
R raise the sliding sunroof/panorama sliding
sunroof fully
R open the boot lid fully
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 panoramas liding sunroof:if a
roof carrier is fitted, the panorama sliding sun-
roof cannot be opened. In order to allow venti-
lation of the vehicle interior, you can raise the
panorama sliding sunroof.
If ar oof carrier approved by Mercedes-Benz
makes contact with the panorama sliding sun-
roof, the sunroof will lower slightly but remain
raised in the rear.
Attaching the roof carrier X
Open covers :carefully in the direction of
the arrow.
X Fold covers :upwards.
X Only secure the roof carrier to the anchorage
points under covers :.

ave work on the batteries carried
out at aqualified specialist workshop. Should
it, in exceptional circumstances, be abso-
lutely necessary to disconnect the 12-volt
battery yourself, please observe the follow-
ing:
R secure the vehicle to prevent it from rolling
away.
R switch the ignition off.
R first, disconnect the negative terminal, fol-
lowed by the positive terminal.
Vehicles with automatic transmission: the
transmission is locked in position Pafter dis-
connecting the battery.
After the work has been completed, firmly
reinstall the battery and the cover of the pos-
itive terminal.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes or clothing.
Wear suitablep rotective clothing, in
particular gloves, an apron and a
face mask.
Immediately rinse electrolyte or acid
splashes off with clean water. Con-
sult adoctor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual. For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz.T
hese batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the battery be damaged in the event of an accident.
In order for the battery to achieve the maximum possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.In such cases, have the battery disconnected ataq ualified specialist workshop. You can also
charge the battery with acharger recommended
by Mercedes-Benz.F or more information,
please contact aqualified specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for alengthy
period. Consult aqualified specialist workshop
if you wish to leave your vehicle parked up for a
long period of time.
When you park the vehicle, remove the key if you do not require any electrical consumers. The
vehicle will then use very little energy, thus con- serving battery power. Charging the 12
Vbattery
Vehicles with alithium-ion battery:
! Only use battery chargers with
amaximum
charging voltage of 14.4 V.
