Cargo net
Important safety notes
GWARNING
Make sure the cargo net is properly engaged
at top and bottom position and the tightening
belts are securely fastened.
Never use a damaged cargo net.
Always use cargo net when transporting
cargo. This helps to avoid personal injury from
smaller objects being thrown around in the
occupant compartment during a collision or
sudden maneuver.
The cargo net cannot prevent the movement
of large, heavier objects into the passenger
compartment in an accident. Such items must
be properly secured using the cargo tie-down
rings in the cargo compartment floor.
Passenger use of seats behind installed cargo
net is restricted because of the footwell being
taken up by the net.
It is particularly important to use a safety net
if the vehicle is loaded with small objects
above the level of the backrests. For safety
reasons, always use a cargo net when
transporting loads.
Preparing the cargo net
The cargo net can be used in two different
positions (behind the B-pillar or the C-pillar).

means of the basic carrier bars being
mounted.
Follow the manufacturer's installation
instructions. Otherwise, an improperly
attached roof rack system or its load could
become detached from the vehicle.

220 lb (100 kg).
Take into consideration that when the roof
rack is loaded, the handling characteristics
are different from those when operating the
vehicle without the roof rack loaded.
! 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
installed you can:
R raise the sliding sunroof fully
R open the panorama roof with power tilt/

equipment, e.g. toll recording systems,
areas : on the windshield are permeable to
radio waves. In these areas, you can install
radio-controlled systems.
These areas can best be seen from outside
the vehicle by observing the light reflected off

not to catch hands or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged
before driving off. Do not continue driving if
the hood can no longer engage after an
accident, for example. The hood could
otherwise come loose while the vehicle is in
motion and injure you and/or others.XLower the hood and let it fall from a height
of approximately 8 inches (20 cm).XCheck that the hood has engaged properly.

Radiator
i Vehicles with a diesel engine: do not
cover the radiator, for example with a
winter front or bug cover. Otherwise, the
readings of the on-board-diagnostic
system may be inaccurate. Some of these
readings are required by law and must be
accurate at all times.
Engine oil
Notes on the oil level
Depending on the driving style, the vehicle
consumes up to 0.9 US qts. (0.8 l) of oil over
a distance of 600 miles (1000 km). The oil
consumption may be higher than this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the oil level using the oil
dipstick
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.

Checking and adding other service
products
Checking the coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the SmartKey to position
2 (Y page 145) in the ignition lock.
On vehicles with KEYLESS-GO, press the
Start/Stop button twice ( Y page 145).XCheck the coolant temperature gauge in
the multifunction display.
The coolant temperature must be below
158 ‡ (70 †).GWARNING
In order to avoid any potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.XSlowly turn cap : half a turn counter-
clockwise and allow excess pressure to
escape.XTurn cap : further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the filler neck when cold, there is
enough coolant in coolant expansion
tank ;.
If the coolant is approximately 0.6 in
(1.5 cm) above marker bar = in the filler
neck when warm, there is enough coolant
in coolant expansion tank ;.XIf necessary, add coolant that has been
tested and approved by Mercedes-Benz.XReplace cap : and turn it clockwise as far
as it will go.
For further information on coolant, see
( Y page 359).
