The red coolant warning lamp comes on while the engine is running.
The coolant level is too low.
If the coolant level is correct, the airflow to the engine radiator may be blocked or the electric engine radiator fan may be defective.
The coolant is too hot and the engine is no longer being cooled sufficiently.
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 (Y page 144).
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
(Y page 299).
X If you have to add 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 snow,
slush or ice.
X Do not start the engine again until the coolant temperature is below 248 ‡
(120 †). Otherwise, the engine could be damaged.

The red coolant warning lamp comes on while the engine is running.
The coolant temperature has exceeded 248 ‡ (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.
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.

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, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey. G
DANGER
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the tail- gate is open while the engine is running, espe-cially if the vehicle is in motion. There is a risk of poisoning.
Always switch off the engine before opening
the tailgate. 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 burns.
Always be particularly careful and supervise
children closely around the exhaust pipe and
the exhaust pipe trims. Allow these compo-
nents to cool down before touching them.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occupants and luggage/cargo.
Do not exceed the load limit or permitted grossvehicle weight rating (GVWR) for your vehicle.
The gross load limit and the GVWR are specified
on the vehicle identification plate on the B-pillar
of the driver's door (Y page 337).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and rear axles. The specifications for GVWR and GAWR
are on the vehicle identification plate on the B-
pillar of the driver's door (Y
page 337).
Observe the notes on loading the vehicle
(Y page 337).
The handling characteristics of a laden vehicle
are dependent on the distribution of the load
within the vehicle. For this reason, you should
observe the following notes when transporting a
load:
R Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
R The cargo compartment is the preferred place
to carry objects.
R Position heavy loads as far forward as possi-
ble and as low down in the cargo compart-
ment 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 cargo tie-down rings and the parcel
nets to transport loads and luggage.
R Use cargo tie-down rings and fastening mate-
rials appropriate for the weight and size of the load.
R Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges for
protection. Stowage spaces
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. 272

R
Always stow objects in such a way that they
cannot be tossed about in these or similar
situations.
R Always make sure that objects do not pro-
trude out of the stowage spaces, luggage

R Ensure that closable stowage spaces are
shut before beginning your journey.
R Always stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or large objects in
