Loading and stowing
146 Securing a load
Lashing eyelets G
Risk of injury
Distribute the load on the lashing eyelets
evenly.
Otherwise, vehicle occupants could be
injured by objects being thrown around if
you:
R brake sharply
R change direction suddenly
R are involved in an accident
Please observe the loading guidelines.
Observe the following points or guidelines
when securing loads:
R Secure the load using the lashing eyelets.
R Do not use elastic straps or nets to secure
a load, as these are only intended as an
anti-slip protection for light loads.
R Do not route lashing materials across sharp
edges or corners.
R Pad sharp edges for protection. Securing loads in the luggage compart-
ment

Lashing eyelets
X Secure the load using lashing eyelets 1or
the mounting cups for the seats, if the seats
have been removed.
Securing a load when the seats have been
removed X
Guide the load restraints in a cross pattern
over the load, as shown in the illustration.
X Secure the load using the lashing eyelets
or the mounting cups on the seats. G
Risk of injury
Always stow the load so that it does not
interfere with driving the vehicle.
Avoid obstructing the driver's line-of-sight.
The load must not protrude above the upper
edge of the door trim if the front-passenger
seat has been removed.
Pad sharp edges for protection. This will
reduce the risk of lacerations and prevent
the load restraints from wearing.
Observe the following notes:
R The load must not protrude above the
upper edge of the door trim.
R Long loads must only be placed low down
and towards the front of the front-
passenger footwell.
! Load restraints must not be fastened to
the front right-hand mounting cup. Other-
wise, the contact switch for the front-
passenger seat could be damaged. Controls

Refuelling
168 Running-in notes
The first 1,500 km
If you treat the engine with sufficient care
from the very start, you will be rewarded with
excellent performance for the remainder of
the engine's life.
R You should therefore drive at varying road
and engine speeds for the first 1,500 km.
R Avoid heavy loads, e.g. driving at full throt-
tle, during this time. Do not exceed 2
/ 3 of
the maximum permissible engine speed for
each gear.
R Change gear in good time.
R Do not shift down a gear manually in order
to brake.
Vehicles with AUTOTRONIC*:
R Try to avoid depressing the accelerator
pedal beyond the pressure point (kick-
down).
R Only use ranges 3,2or 1for slow driving,
e.g. in mountainous terrain.
After 1,500 km you may gradually bring the
vehicle up to full road and engine speeds. Refuelling
Refuelling
G
Risk of explosion
Fuel is highly flammable. Fire, naked flames
and smoking are therefore prohibited when
handling fuels.
Switch off the engine before refuelling. G
Risk of injury
Avoid any contact with fuels.
You can damage your health if your skin
comes into direct contact with fuel or if you
inhale fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with a
diesel engine. Never mix diesel with petrol.
This causes damage to the fuel system and
engine and could result in the vehicle catch-
ing fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
injection system. Damage resulting from
adding the wrong fuel is not covered by the
warranty. !
Do not start the engine if you accidentally
refuel with the wrong fuel. Otherwise, the
fuel could enter the fuel lines. This would
require draining of the fuel tank and fuel
lines. Notify a qualified specialist workshop
and have the fuel tank and fuel lines
drained completely.
When you open or close the vehicle with the
key, the fuel filler flap is automatically
unlocked or locked.
The position of the fuel filler cap is to the rear
on the right. The fuel tank filler flap is shown
in the instrument cluster 4. The arrow on
the filling pump indicates the side of the vehi-
cle. 1

X Close the fuel filler flap.
i Vehicles with a diesel engine:
if the fuel tank has been run completely dry,
it will be necessary to bleed the fuel system
(Y page 232). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228.
You could otherwise impair engine output
or damage the engine.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be adequate and could cause
coking around the inlet valve. In such
cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
For further information on "Fuel" see
(Y page 291). Turbo engines !
Refuel using only unleaded Super Plus
with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
You could otherwise impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle. Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
You could otherwise impair engine output
or damage the engine.
You will find further information about die-
sel under "Fuel" in the index.
! When refuelling vehicles with a diesel par-
ticle filter in countries outside the EU, only
low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
should be used. In countries in which diesel Operation

Bonnet
G
Risk of accident
Do not pull the release lever while the vehi-
cle is in motion. If you do so, the bonnet
may open up and block your view.
Opening G
Risk of injury
There is a risk of injury if the bonnet is open,
even if the engine is not running.
Some engine components can become
very hot.
To avoid the risk of burns, only touch those
components described in the Owner’s Man-
ual and observe the relevant safety notes. G
Risk of injury
The radiator fan between the radiator and
the engine can start automatically, even if
the key has been removed from the ignition
lock. For this reason, you must not reach
into the fan rotation area. Otherwise, you
could be injured. Vehicles with a petrol engine:
The electronic ignition system uses high
voltage. For this reason, you must never
touch components of the ignition system
(ignition coil, ignition cable, spark plug con-
nector or test socket) when:
R
the engine is running.
R the engine is being started.
R the ignition is switched on and the engine
is being cranked by hand.
Vehicles with a diesel engine:
The electronic injection control uses high
voltage. Therefore, never touch fuel injec-
tion system components when:
R the engine is running.
R the engine is being started.
R the ignition is switched on.
X Make sure that the windscreen wipers are
switched off. G
Risk of injury
The windscreen wipers and wiper linkage
could be set in motion.
When the bonnet is open, you or others
could be injured by the wiper rods. Make sure that the windscreen wipers are
switched off and that the key has been
pulled out of the ignition lock before open-
ing the bonnet.
The bonnet release lever is located in the

Depending on driving style, the vehicle con-
sumes a maximum of 0.8 l oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds. You can only
estimate the oil consumption after you have
driven a considerable distance.
For further information on engine oil see
(Y page 295).
Checking the engine oil level To do so:
R
the vehicle should be parked on level

R the engine should be switched off for at
least five minutes if the engine was at nor-
mal operating temperature.
