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

The yellow tire pressure
monitor warning lamp
(pressure loss/
malfunction) is lit.The tire pressure monitor has detected a loss of pressure in at
least one of the tires.
GWARNING
With tire pressures which are too low, there is a risk of the fol-
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.
Rthe 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 maneuvers. Pay attention to the traffic conditions as you do so.
XSecure the vehicle against rolling away (Ypage 151).
XObserve the additional display messages in the multifunction

ests can be folded down separately to
increase the trunk capacity.
Folding the seat backrest forward
iVehicles with memory function: when you
fold one or both parts of the rear seat back-
rest forwards, the respective front seat
moves forward slightly, when necessary, in
order to avoid contact.
XVehicles without memory function: if nec-
essary, move the driver's or front-
passenger seat forward.
XOpen the trunk.

Plastic hooks (Sedan)
On vehicles without a through-loadin g feature
in the rear bench seat, six plastic hooks are
installed to the trunk floor.
Cargo tie-down rings
General notes
Observe the fol lowing notes on securing
loads:
RObserve the loading guidelines
(
Ypage 238).
RSe cure the load using the cargo tie-down
rings.
RDistribute the load on the cargo tie-down
rings evenly.
RDo not use elastic straps or nets to secure
a load, as these are only intended as an
anti-s lipprotection for light loads.
RDo not route tie-down s across sharp edges
or corners.
RPad sharp edges for protection.

Checking coolant level
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
GWARNING
The engine cooling system is pressurized, par-
ticularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolant spraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape.
XPark the vehicle on a level surface.
Only check the coolant level when the vehi-
cle is on a level surface and the engine has
cooled down.
XTurn the SmartKey to position 2in the igni-
tion lock (
Ypage 137).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (
Ypage 138).
XCheck the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
XTurn the SmartKey to position 0in the igni-
tion lock (
Ypage 137).
XSlowly turn cap :half a turn counter-
clockwise to allow excess pressure to
escape.
XTurn cap :further counter-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.

TIREFIT kit
Important safety notes
TIREFIT is a tire sealant.
You can use TIREFIT to seal punctures of up to
0.16 in (4 mm), particularly those in the tire
tread. You can use TIREFIT at outside tem-
peratures down to Ò4 ‡ (Ò20 †).
GWARNING
In the following situations, the tire sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tire properly:
Rthere are cuts or punctures in the tire larger
than those mentioned above.
Rthe wheel rim is damaged.
Ryou have driven at very low tire pressures or on a flat tire.
There is a risk of an accident.
Do not drive the vehicle. Contact a qualified
specialist workshop.
GWARNING
The tire sealant is harmful and causes irrita-
tion. It must not come into contact with your
skin, eyes or clothing or be swallowed. Do not inhale TIREFIT fumes. Keep tire sealant away
from children. There is a risk of injury.
If you come into contact with the tire sealant,
observe the following:
RRinse off the tire sealant from your skin
immediately with water.
RIf the tire sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
RIf tire sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately.
RImmediately change out of clothing which
has come into contact with tire sealant.
RIf an allergic reaction occurs, seek medical
attention immediately.
!Do not operate the tire inflation compres-
sor for longer than eight minutes at a time
without a break. It may otherwise overheat.
The tire inflation compressor can be oper-
ated again once it has cooled down.
Comply with the manufacturer’s safety
instructions on the sticker on the tire inflation
compressor.
Using the TIREFIT kit
XDo not remove any foreign objects which
have penetrated the tire, e.g. screws or
nails.
XRemove the tire sealant bottle, the accom-
panying TIREFIT sticker and the tire infla-
tion compressor from the stowage well
underneath the trunk floor/cargo compart- ment floor (
Ypage 270).
XAffix part :of the TIREFIT sticker to the
instrument cluster within the driver's field
of vision.
XAffix part ;of the TIREFIT sticker near the
valve on the wheel with the defective tire.
