The red coolant warn-
ing lamp comes on
while the engine is run-
ning. A warning tone
also sounds.The coolant temperature has exceeded 248 ‡ (120 †). The air-
flow to the engine radiator may be blocked or the coolant level may
be too low.
GWARNING
The engine is not being cooled sufficiently and may be damaged.
Do not drive when your engine is overheated. This can cause some
fluids which may have leaked into the engine compartment to
catch fire.
Steam from the overheated engine can also cause serious burns
which can occur just by opening the hood.
There is a risk of injury. X Observe the additional display messages in the multifunction display.
X Pull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
X Secure the vehicle against rolling away ( Ypage 110).
X Leave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
X Check the coolant level and add coolant, observing the warning
notes ( Ypage 208).
X If you need to add coolant more often than usual, have the
engine coolant system checked.
X Make sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
X At coolant temperatures below 248 ‡ (120 †), drive to the
nearest qualified specialist workshop.
X Avoid subjecting the engine to heavy loads, e.g. driving in moun-
tainous terrain, and stop-start driving.

Observe the following notes when transport-
ing a load:
R Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible.
iTransport 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.
R Always place the load against the backrests
of the front seats or rear seats.
R Use the cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
If the rear bench seat is not occupied: XInsert the belt tongue on the outer seat
belts into the buckle of opposite seat
belt :.
X Secure the load with sufficiently strong and
wear-resistant tie downs.
X Pad sharp edges for protection.

Important safety notes
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants.
There is a risk of injury, particularly in the
event of sudden braking or a sudden change
in direction. R Always stow objects so that they cannot be
thrown around in such situations.
R Always make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
R Close the lockable stowage spaces while
driving.
R Stow and secure objects that are heavy,
hard, pointy, sharp-edged, fragile or too
large in the cargo compartment.
Observe the loading guidelines ( Ypage 192).

Do not tamper with or repair cargo tie-down
points, cargo tie-down rings or tie downs.
Have maintenance work as well as modifica-
tions, installations and conversions carried
out at a qualified specialist workshop(Y page 28).
Observe the following notes on securing
loads:
R Secure the load using the cargo tie-down
rings.
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 tie-downs across sharp edges
or corners.
R Pad sharp edges for protection.
R Only use tie downs that have been checked
in accordance with applicable standards,
e.g. lashing nets or lashing straps.
R Fill the spaces between the load and the
cargo compartment walls and the wheel
housing in a form-locking way. Only use
dimensionally stable transportation aids
for this, such as chocks, wooden fixings or
padding.
Cargo tie-down rings in the cargo com-
partment
There are four cargo tie-down rings :in the
cargo compartment mounted at the sides.
Cargo compartment cover
Important safety notes
GWARNING
On its own, the cargo compartment cover
cannot secure or restrain heavy objects,
items of luggage and heavy loads. You could
be hit by an unsecured load during sudden
changes in direction, braking or in the event of an accident. There is an increased risk of
injury or even fatal injury.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping over, e.g. by
using tie downs, even if you are using the
cargo compartment cover.
!When loading the vehicle, make sure that
you do not stack the load in the cargo com-
partment higher than the lower edge of the side windows. Do not place heavy objects
on top of the cargo compartment cover.
The cargo compartment cover is located
behind the rear bench seat backrest.
Opening and closing the cargo compart-
ment cover
X To open: pull cargo compartment cover :
back and clip it into the retainers on the left and right of the rear door.
X To close: unclip cargo compartment
cover :and guide it forwards until it is
completely rolled up.
