94StorageFasten the roof rack in the area of the
holes, indicated by the arrows in the
illustration.
Vehicles without roof railing
To fasten a roof rack, open the caps
in the roof strips. Insert the mounting
provisions, as instructed, in the
retainer indicated in the illustration.
Loading information
● Heavy objects in the load compartment should be placed
against the seat backrests.
Ensure the backrests are
securely engaged. If objects can
be stacked, the heavier objects should be placed at the bottom.
● Secure objects with lashing straps attached to lashing eyes
3 88.
● Secure loose objects in load compartment to prevent sliding.
● Do not allow the load to protrudeabove the upper edge of the
backrests.
● Do not place any objects on the load compartment cover or the
instrument panel.
● The load must not obstruct the operation of the pedals, parking
brake and gear selector lever, or
hinder the freedom of movement of the driver. Do not place any
unsecured objects in the interior.
● Do not drive with an open load compartment.9Warning
Always make sure that the load in
the vehicle is securely stowed.
Otherwise objects can be thrown
around inside the vehicle and
cause personal injury or damage
to the load or car.
● The payload is the difference between the permitted gross
vehicle weight (see identification
plate 3 272) and the EC kerb
weight.
Page 97 of 305
Storage95To calculate the payload, enter
the data for your vehicle in the
Weights table at the front of this
manual.
The EC kerb weight includes
weights for the driver (68 kg),
luggage (7 kg) and all fluids (tank 90% full).
Optional equipment and
accessories increase the kerb
weight.
● Driving with a roof load increases
the sensitivity of the vehicle to
cross-winds and has a
detrimental effect on vehicle
handling due to the vehicle's
higher centre of gravity.
Distribute the load evenly and secure it properly with retaining
straps. Adjust the tyre pressure
and vehicle speed according to
the load conditions. Check and
retighten the straps frequently.
Do not drive faster than 75 mph.
The permissible roof load is
75 kg for vehicles without roof
railing and 100 kg for vehicles
with roof railing. The roof load isthe combined weight of the roof
rack and the load.

Driving and operating213Vehicles with misfuel inhibitor9Warning
Do not try to open the flap of the
fuel filler neck manually on
vehicles with misfuel inhibitor.
Disregarding this could lead to
trapping of the fingers.
Vehicles with a selective catalytic
reduction system are equipped with a
misfuel inhibitor.
The misfuel inhibitor ensures that the flap of the fuel filler neck can only be
opened by using a nozzle for diesel
fuel or a funnel for emergency
refilling.
Turn the fuel filler cap slowly
anticlockwise.
The cap can be retained in the
bracket on the fuel filler flap.
Place the nozzle in a straight line to the filler neck and press with slight
force to insert.
In case of an emergency refill with a
canister, a funnel must be used to
open the cap of the filler neck.The funnel is located on the right-
hand side storage compartment in the load compartment.
Place the funnel in a straight line to
the filler neck and press with slight force to insert.
Use the funnel to fill the diesel fuel into
the filler neck.
After topping-up, put the funnel into
the plastic bag and stow it in the storage compartment.

Vehicle care223General Information
Accessories and vehicle modifications
We recommend the use of genuine
parts and accessories and factory
approved parts specific for your
vehicle type. We cannot assess or guarantee reliability of other products
- even if they have a regulatory or
otherwise granted approval.
Do not make any modifications to the
electrical system, e.g. changes of
electronic control units (chip tuning).Caution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, well ventilated place. Engage first or
reverse gear or set selector lever
to P. Prevent the vehicle from
rolling.
● Do not apply the parking brake.● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems
are not functional, e.g. anti-theft
alarm system.
Putting back into operation
When the vehicle is to be put back into
operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Activate the electronics
of the power windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plate if necessary.
End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our
Page 228 of 305
226Vehicle careWhen the engine oil level has
dropped to the MIN mark, top-up
engine oil.
We recommend the use of the same
grade of engine oil that was used at
last change.
The engine oil level must not exceed
the MAX mark on the dipstick.
On some engines, a funnel is needed to top-up engine oil.
The funnel is located on the right side storage in the load compartment.
Use the funnel to fill in the engine oil
into the engine oil opening.
After topping-up, put the funnel into the plastic bag and stow it in thestorage compartment.
Caution
Overfilled engine oil must be
drained or suctioned out.
Capacities 3 286.
Fit the cap on straight and tighten it.
Engine coolant
The coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.

Have bulbs replaced by a workshop.Electrical system
Fuses Data on the replacement fuse must
match the data on the defective fuse.
There are three fuse boxes in the vehicle:
● in the front left of the engine compartment
● in left-hand drive vehicles, in the interior behind the storage
compartment, or, in right-hand
drive vehicles, behind the
glovebox
● behind a cover on the left side of the load compartment
Before replacing a fuse, turn off the
respective switch and the ignition.
There are different kinds of fuses in
the vehicle.

Instrument panel fuse box
In left-hand drive vehicles, the fuse
box is behind the storage
compartment in the instrument panel.
Open the compartment and push it to the left to unlock. Fold the
compartment down and remove it.
