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.
XObserve the additional display messages in the multifunction
display.
XPull over and stop the vehicle safely and switch off the engine,
paying attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 151).
XLeave the vehicle and keep a safe distance from the vehicle until
the engine has cooled down.
XCheck the coolant level and add coolant, observing the warning
notes (
Ypage 265).
XIf you need to add coolant more often than usual, have the
engine coolant system checked.
XMake sure that the air supply to the engine radiator is not
blocked, e.g. by snow, slush or ice.
XAt coolant temperatures below 248 ‡(120†) ,dr ive to the
nearest qualified specialist workshop.
XAvoid subjecting the engine to heavy loads, e.g. driving in moun-
tainous terrain
, and stop-and-go traffic.

lowing hazards:
Rthey may burst, especially as the load and vehicle speed
increase.
Rthey may wear excessively and/or unevenly, which may greatly
impair tire traction.

Procedure and general information
Searching for and authorizing (connect-
ing) a mobile phone
Before using your mobile phone with Audio
20/COMAND for the first time, you will need
to search (
Ypage 229) for the phone and
then authorize it (
Ypage 229). Depending on
the mobile phone, authorization either takes
place by means of Secure Simple Pairing or by
entering a passkey. Audio 20/COMAND
automatically makes the system suitable for
your mobile phone available. You can recog-
nize Secure Simple Pairing by a code which is displayed in Audio 20/COMAND and on the
mobile phone. You can recognize the passkey
system by the fact that you have to enter a
code on the mobile phone and in Audio 20/
COMAND. The mobile phone is always con-
nected automatically after authorization.
If Audio 20/COMAND does not detect your
mobile phone, this may be due to particular
security settings on your mobile phone. You
can also start the search procedure and
authorization on the mobile phone
(
Ypage 230).
Device-specific information on authorizing
and connecting Bluetooth
®-capable mobile
phones can be found on the Internet at

Useful information
i
This Operator's Manual describes all
models and all standard and optional equip-
ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and
functions.
iRead the information on qualified special-
ist workshops (
Ypage 31).
Stowage areas
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, 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.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid/tailgate is open when the engine is
running, especially if the vehicle is in motion.
There is a risk of poisoning.
Always switch off the engine before opening
the trunk lid/tailgate. Never drive with the
trunk lid/tailgate open.
GWARNING
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 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:
RNever exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle
identification plate on the B-pillar of the
driver's door.
RThe trunk/cargo compartment is the pre-
ferred place to store objects.
RPosition heavy loads as far forwards as pos-
sible and as low down in the trunk/cargo
compartment as possible.
RThe load must not protrude above the
upper edge of the seat backrests.
RAlways place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
RAlways place the load behind unoccupied
seats if possible.
RUse the cargo tie-down rings and the parcel
nets to transport loads and luggage.
RUse cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load.
RWhen transporting objects in the cargo
compartment, the combined cargo cover
and net must always be installed (cargo
compartment cover and cargo net).
RSecure the load with sufficiently strong and
wear-resistant tie-downs. 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.
RAlways stow objects so that they cannot be
thrown around in such situations.
RAlways make sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces while
driving.
RAlways stow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk/cargo compartment.
Observe the loading guidelines (Ypage 238).

Important safety notes
GWARNING
If the rear bench seat/rear seat and seat
backrest are not engaged they could fold for-
wards, e.g. when braking suddenly or in the
event of an accident.
RThe vehicle occupant would thereby be
pushed into the seat belt by the rear bench
seat/rear seat or by the seat backrest. The
seat belt can no longer offer the intended
level of protection and could even cause
injuries.
RObjects or loads in the trunk cannot be
restrained by the seat backrest.
There is an increased risk of injury.
