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 malfunctioning.
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 Stop the vehicle immediately, paying attention to road and traffic conditions,
and switch off the engine.
X Safeguard the vehicle against rolling away (Y page 167).
X Leave the vehicle and keep a safe distance from the vehicle until the engine has
cooled down.
X Check the coolant level and top up the coolant, observing the warning notes
(Y page 321).
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.
X Drive to the nearest qualified specialist workshop.
X Avoid heavy loads on the engine as you do so, e.g. driving in mountainous terrain
and stop-start traffic. ?

The red coolant warning lamp comes on while the engine is running.
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 is overheated
can cause some fluids which 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.

lit.
The tyre pressure monitor has detected a loss of pressure in at least one of the
tyres.
G WARNING
Underinflated tyres pose the following risks:
R the tyres may burst, especially as the load and vehicle speed increase
R the tyres may wear excessively and/or unevenly, which may greatly impair tyre
traction
R the driving characteristics, as well as steering and braking, may be greatly
impaired
There is a risk of an accident.
X Stop the vehicle without making any sudden steering or braking manoeuvres.
Pay attention to the traffic conditions as you do so.
X Safeguard the vehicle against rolling away (Y page 167).
X Observe the additional display messages in the multifunction display.

Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 25). Stowage areas
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. For this reason, you should
observe the following notes when 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 load 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 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 secure the load with sufficiently strong and
wear-resistant lashing material. pad sharp
edges for protection.
i Load restraints are available at any qualified
specialist workshop, e.g. a Mercedes-Benz
Service Centre. Stowage compartments
Important safety notes G
WARNING
If you do not correctly store objects in the
vehicle interior, they can slip or be flung
around, thus striking vehicle occupants.
There is a risk of injury, especially when brak- ing or abruptly changing directions.
R Always store objects so that they cannot be
flung around in these or in similar situa-
tions.
R Always make sure that objects do not pro-
trude from stowage compartments, lug-
gage nets or stowage nets. Stowage areas
