General notes
Some systems perform a self test when the ignition is switched on. Some warning and indicator
lamps may temporarily switch on or flash during the test. This behaviour is nothing to be concerned about.
The warning and indicator lamps will alert you to a malfunction if they switch on or flash after the
engine is started or while driving. 264

The red coolant warning lamp lights up while the engine is running.
The coolant level is too low.

X Check the coolant level and top up the coolant, making sure to observe the
warning notes (Y page 305).
X If you have to top up the coolant frequently, have the engine cooling system
checked.
X Make sure that the air supply to the engine radiator is not blocked, e.g. by frozen
slush.
X Do not start the engine again until the coolant temperature is below 120 †. The
engine may otherwise be damaged.

The red coolant warning lamp lights up while the engine is running. A warning
tone also sounds.
The coolant temperature has exceeded 120 †. The airflow to the engine radiator may be blocked or the coolant level may be too low.
G WARNING
The engine is not being cooled sufficiently and may be damaged.
Never drive with an overheated engine. Driving when your engine has overheated
can cause any fluids that may have leaked into the engine compartment to catch fire.
In addition, steam from an overheated engine can cause serious burns, which can
occur just by opening the bonnet.
There is a risk of injury.

Loading guidelines
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 a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open. 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 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.
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle.
Observe the following notes on loading and
transporting a load:
R never exceed the maximum permissible gross
vehicle weight or the permissible axle loads
for the vehicle (including occupants).
R the luggage compartment is the preferred
place to store objects.
R position heavy loads as far forwards as pos-
sible and as low down in the luggage com-
partment as possible. R
the load must not protrude above the upper
edge of the seat backrests.
R always place the load against the rear or front
seat backrests. Make sure that the seat
backrests are securely locked into place.
R always place the load behind unoccupied
seats if possible.
R use the lashing eyelets and the luggage nets
to transport loads and luggage.
R only use lashing eyelets and fastening com-
ponents that are suitable for the weight and
size of the load.
R the maximum load capacity of the stowage
well under the luggage compartment floor is
25 kg.
R secure the load with sufficiently strong and
wear-resistant lashing material. Pad sharp
edges for protection.
! Do not position the load on one part of the
folding luggage compartment floor only. The
maximum load capacity of the folding luggage compartment floor is 100 kg. Spread the
weight evenly to avoid damaging the luggage
compartment floor. Place a solid board under the load if necessary. Please note that the
load on the luggage compartment floor will be increased when the load is lashed down. Stowage areas
Stowage compartments
Important safety notes G
WARNING
If you transport objects in the vehicle interior and these are not adequately secured, they
could slip or be flung around and thereby
strike vehicle occupants. In addition, cup
holders, open stowage spaces and mobile
phone brackets may not always be able to
hold the objects placed in them in the event of an accident. There is a risk of injury, particu-
larly in the event of sharp braking or sudden
changes of direction. 288

passenger seat
G
WARNING
If the backrest of the co-driver's seat is folded forward, passengers in the rear compartment
could collide with parts of the seat mecha-
nism, particularly in the event of an accident,
heavy braking or sudden changes of direction.
There is a risk of injury.
If another person is travelling in the vehicle
when the backrest of the co-driver's seat is
folded forward, this person must sit on the
rear seat behind the driver.
The backrest of the front-passenger seat can be
folded forwards to increase the luggage com-
partment capacity.
Once you no longer need the backrest on the
front-passenger side to be used as a load sur-
face, fold the backrest back into place. X
To fold forward: gently push the backrest
back.
X Pull release handle :and fold the backrest
fully onto the seat cushion until it engages.

Lashing eyelets Observe the following notes on securing loads:
R Observe the loading guidelines (Y page 288).
R Secure the load using the lashing eyelets.
R Distribute the load on the lashing eyelets
evenly.
R Do not use elastic straps or nets to secure a
load. These are intended only as anti-slip pro-
tection for light loads.
R Do not route lashing materials across sharp
edges or corners.
R Pad sharp edges for protection. :
Lashing eyelets
Bag hooks G
WARNING
The bag hooks cannot restrain heavy objects
or items of luggage. Objects or items of lug-
gage could be flung around and thereby hit
vehicle occupants when braking or abruptly
changing directions. There is a risk of injury.
Only hang light objects on the bag hooks.
Never hang hard, sharp-edged or fragile
objects on the bag hooks.
! The bag hook can bear a maximum load of
3 kg. Do not use it to secure a load. Stowage areas
