WARNING
If you shift down on aslippery road surfac ein
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface. G
DANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible ,poisonous gases
such as carbon monoxide (CO) may enter the
vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is arisk of
fatal injury.
If you leave the engine or the auxiliary heating
running, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open
aw indow on the side of the vehicle that is not
facin ginto the wind.
! Take care not to damage the sealing strip
and the mould ingont he side of the rear

Bonnet
Active bonnet (pedes tria np rotection) Operating principle
!
An activ ebonnet that had been triggered
must be repaired at aqualified specialist
workshop. The activ ebonnet function will
then be available again .The additional
pedestrian protection provided by the
activ ebonnet will then be restored.
i The activ ebonnet is only available in cer-
tain coun tries. It is available for all models,
except for AMG vehicles.
The activ ebonnet can reduce the risk of injury
to pedestrians in cer tain acciden tsituations.
Raising the active bonnet increases the clear-
anc etoh ard components, such as the engine.
If the active bonnet has been triggered, it will
be raised in the area of the bonnet hinges by
approximately 100 mm. The active bonnet is
triggered by pyrotechnics.
For the drive to the workshop, reset the trig-
gered active bonnet yourself .After be ing
reset, th eactive bonnet rest sinthe area of
the bonnet hinges on the seals, and the bon-
net hinges do not enga ge.For this rea son, we
recommend that you do not excee damaxi-
mum top spee dof130 km/h on the wa yto

An emergenc ycut-off ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, the power to
the sockets is automatically cut. This
ensures that there is sufficient power to
start the engine. MOExtended tyres (tyres with run-flat

WARNING
When driving in emergenc ymode, the driving
characteristic sdeteriorate, e.g. when cor ner-
ing, accelerating quickly and when braking.
There is arisk of accident.
Do not exceed the stated maximum speed.
Avoid abrupt steering and drivin gmanoeu-
vres, and driving over obstacles (kerbs, pot-
holes ,off-road) .This applies in particular to a
laden vehicle.

R there are tears in the sidewall softhe tyre.
After driving in emergency mode, have the
whee lrims checked at aquali fied specialist
workshop with regar dtotheir furthe ruse. The
fault ytyre must be replaced.
With MOExtended tyres (tyres with run-flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or mor etyres.
MOExtended tyres may only be used in con-
junction with an active tyre pressure loss
warning syste morwith an activ etyre pres-
sure monitor.
The maximum driving distance is approx-
imately 80 km when the vehicle is partially
laden, and approximatel y30kmwhen the
vehicle is fully laden.
In addition to the vehicle load, the drivin gdis-
tance possible depends upon:
R speed
R road condition
R outside temperature
The drivin gdistance possible in run-flat mode
may be reduced by extrem edriving condi-
tions/manoeuvres ,oritcan be increased
through amoderate style of driving.
The maximum permissible distance which
can be driven in run-flat mode is counted from
the moment the tyr epressure loss warning
appe arsint he multifunction display.
You must not exceed amaximum spee dof
80 km/h.
i When replacing one or all tyres, make
sure tha tyou only use tyres marked
"MOExtended". Make sure that you only
use the size of tyr especified for the vehicle.
i Vehicles with MOExtended tyres are not
equipped with aTIREFIT kit at th efactory.
It is therefore recommended that you addi-
tionally equip your vehicle with aTIREFIT kit
if yo ufit tyres that do not featur erun-flat
characteristics, e.g. winter tyres. ATIREFIT kit can be obtaine
dfrom aqualified spe-
cialist workshop. TIREFIT kit
Usin gthe TIREFIT kit TIREFIT is
atyre seal ant.
You can use TIREFIT to seal punctures of up
to 4m m, particularl ythose in the tyr etread.
Yo uc an use TIREFI Tatoutside temperatures
down to Ò20 †. G
WARNING
In the following situations, the tyre sealant is
unable to provide sufficient breakdown assis-
tance, as it is unable to seal the tyre properly:
R there are cuts or punctures in the tyre
larger than those mentioned above.
R the wheel rim is damaged.
R you have driven at very low tyre pressures
or on aflat tyre.
There is arisk of accident.
Do not drive any further. Contact aqualified
specialist workshop. G
WARNING
The tyre 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 tyre sealant away
from children. There is arisk of injury.
If you come into contact with the tyre sealant,
observe the following:
R Rinse off the tyre sealant from your skin
immediately with water.
R If the tyre sealant comes into contact with
your eyes, immediately rinse them thor-
oughly with clean water.
R If tyre sealant is swallowed, immediately
rinse your mouth out thoroughly and drink
plenty of water. Do not induce vomiting,
and seek medical attention immediately. Flat tyre

Do not switch off the tyr einfla tion com-
pressor during this phase.
X Let the tyre inflation compresso rrun for
five minutes. The tyre should then have
attained apressure of at leas t180 kPa
(1.8 bar/26 psi).

It can then be removed like alayer of film.
If you get tyre sealant on you rclothing,
have it cleaned as soon as possible with
perchloroethylene.
Tyre pressur enot reached If
ap ressure of 180 kPa (1.8 ba r/26 ps i)has
not been achieved after five minutes:
X Switc hoff th etyre inflation compressor.
X Unscrew the filler hos efrom the valve of
the faulty tyre.
X Very slowly drive forwards or reverse

X Pum pupt he tyreagain.
Af teram aximum of five minutes the tyre
pressure must be at least 180 kPa (1.8 bar/

WARNING
If the required tyre pressure is not reached
after the specified time, the tyre is too badly
damaged. The tyre sealant cannot repair the
tyre in this instance. Damaged tyres and atyre
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.

You should therefor eadapt your driving style
accordingly and driv ecarefully. Do not exceed

After use, excess tyre seal antm ay run out
of the filler hose. This could cause stains.
Therefore, place the filler hos einthe plastic

Environmenta
lnote
Have the used tyre sealant bottle disposed of
professionally, e.g. at aqualified specialist
workshop.
If at yrep ressure of 18 0kPa (1. 8bar/2 6psi)
has been attained after five minutes:
X Switc hoff th etyre inflation compressor.
X Unscrew the filler hos efrom th evalve of
the faulty tyre.
X Stow the tyre sealant bottle, the tyre infla-
tion compressor and the warning triangle.
X Pull away immediately.
The maximum spee dfor atyre sealed with
tyre sealant is 80 km/h. The upper part of
the TIREFI Tsticker must be affixed to the
instrument cluster in the driver's field of
vision.
X Stop after driving for approximately ten
minutes and check the tyre pressure with
the tyre inflation compressor.
The tyre pressure must now be at least
130 kPa (1.3 bar/19 psi). G
WARNING
If the required tyre pressure is not reached
after driving for ashort period, the tyr eistoo
badly damaged. The tyr esealant can not
re pair the tyr einthis instance. Damaged tyres
and atyre pressure that is too low can signif-
icantly impair the vehicle's braking and driv-
ing characteristics. There is arisk of accident.
Do not continue driving. Contact aqualified
specialist workshop.
X Correct the tyre pressure if it is still at least
130 kPa (1.3 bar/19 psi) (see the fuel filler
flap for values).
X To increase the tyre pressure: switch on
the tyre inflation compressor. Flat tyre
