Loading guidelines
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
If you distribute the load unevenly in the vehi- cle, the handling as well as the steering and
braking characteristics are severely affected.
There is a risk of an accident.
Distribute the load evenly in the vehicle.
Secure the load to prevent it from slipping.
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.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the rear
door is open when the engine is running, par-
ticularly if the vehicle is moving, exhaust
fumes could enter the passenger compart-
ment. There is a risk of poisoning.
Turn off the engine before opening the rear
door. Never drive with the rear door open.
Driving, braking and steering characteristics
change depending on:
Rtype of load
Rweight
Rthe center of gravity of the load
You should therefore load your vehicle as shown
in the illustrations.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, accessories installed, vehicle occupants
and luggage/load.
Do not exceed the load limit or permitted gross
vehicle weight rating (GVWR) for your vehicle.
The load limit and GVWR are given on the vehicle
identification plate found on the driver's door B-
pillar.
Furthermore, the load must be distributed in
such a way that the weight on each axle never
exceeds the gross axle weight rating (GAWR) for
the front and rear axles. The relevant GVWR and
GAWR information can be found on the vehicle
identification plate on the driver's side B-pillar.
Further information can be found in the "Loading
the vehicle" section (
Ypage 266).
Observe the following notes when transporting
a load:
RPosition heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment as possible.
RTransport loads when possible in the cargo
compartment. You should only use the cargo
compartment enlargement if the load does
not fit in the cargo compartment.

Notes on the oil level
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 mile s(1000 km). The oil consumption may
be higher than this when the vehicle is new or if you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
When checking the oil level:
Rpark the vehicle on a level surface
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature
Rif the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait approximately 30 minutes before
carrying out the measurement
Checking the oil level using the oil dip-
stick
Example: engine compartment
On the G 63 AMG, the oil level can be checked
using the oil dipstick.
XPull oil dipstick :out of the dipstick guide
tube.
XWipe off oil dipstick :.
XSlowly slide oil dipstick :into the guide tube
to the stop and take it out again after approx-
imately three seconds.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
XIf the oil level has dropped to MIN mark =or
below, add 1.1 US qt (1.0 l)of engine oil.
On all other models, the on-board computer
must be used to check the engine oil level.
Checking the oil level using the on-
board computer
G 550: the oil level can only be checked using
the on-board computer.
XMake sure that the SmartKey is in position 2
in the ignition lock.

Adding engine oil
!Use only engine oils and oil filters that are
approved for vehicles with a service system. A
list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any authorized
Mercedes-Benz Center.
The following cause engine failure or damage
to the exhaust system:
RUse of engine oils and oil filters that have
not been expressly approved for the service
system
RReplacement of engine oil and oil filter after
the replacement interval specified by the
service system has expired
RUse of engine oil additives
!Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
Example: engine oil cap
XTurn cap :counter-clockwise and remove it.
XAdd the amount of engine oil required.
Observe the specifications in the on-board com-
puter when doing so or fill carefully to the max-
imum mark on the oil dipstick.
The difference between the minimum mark and
the maximum mark on the oil dipstick is approx-
imately 2.1 US qt (2.0 l).
XReplace cap :on the filler neck and tighten
clockwise.
Ensure that the cap locks into place securely.
