The red coolant warn-
ing lamp comes on
while the engine is run-
ning. 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.GWARNING
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.
Steam from an overheated engine can cause serious burns which
can occur just by opening the bonnet.
This poses a risk of injury.

The yellow tyre pres-
sure monitor warning
lamp (pressure loss/
malfunction) is lit.The tyre pressure monitor has detected a loss of pressure in at
least one of the tyres.GWARNING
With tyre pressures which are too low, there is a risk of the fol-
lowing hazards:
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.
XStop the vehicle without making any sudden steering or braking
manoeuvres. Pay attention to the traffic conditions as you do
so.XSecure the vehicle against rolling away ( Y page 162).XObserve the additional display messages in the multifunction
display.XCheck the tyres and, if necessary, follow the instructions for a
flat tyre ( Y page 298).XCheck the tyre pressure ( Y page 322).XIf necessary, correct the tyre pressure.h
The yellow tyre pres-
sure monitor warning
lamp (pressure loss/
malfunction) flashes for
approximately one
minute and then
remains lit.The tyre pressure monitor is faulty.GWARNING
The system is possibly unable to recognise or register low tyre
pressure.
There is a risk of an accident.

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos-
sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: ( Y page 24).
Loading guidelines
GWARNING
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.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the boot
lid is open when 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 boot lid. Never drive with the boot lid
open.
The handling characteristics of a laden vehi-
cle 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 when transporting a load, never exceed the
maximum permissible gross vehicle weight
or the permissible axle loads for the vehicle
(including occupants).
R the boot is the preferred place to carry
objects.
R position heavy loads as far forwards as pos-
sible and as low down in the boot as pos-
sible.
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 Lashing material is available at any quali-
fied specialist workshop.

Important safety notes
GWARNING
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.

sudden braking or a sudden change in direc-
tion.
