use the power socket in the luggage com-
partment (Y page 205) or rear compart-
ment (Y page 205), even when the ignition
is switched off. For example, to use TIREFIT
or to inflate the collapsible emergency
spare wheel*.
An emergency cut-off ensures that the on-
board voltage does not drop too low. If the
on-board voltage is too low, power to the
sockets is automatically cut-off. This
ensures that there is sufficient power to
start the engine.

324 Using the TIREFIT kit
You can use the TIREFIT kit to seal small
punctures, particularly those in the tyre tread.
You can use TIREFIT in outdoor temperatures
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and tyre sealant is unable to
provide breakdown assistance:
R if there are cuts or punctures in the tyre
greater than 4 mm
R if the wheel rim is damaged
R if you have driven at very low tyre pres-
sures or on a flat tyre
Do not drive any further. Consult a qualified
specialist workshop which has the neces-
sary specialist knowledge and tools to carry
out the work required.
Mercedes-Benz recommends that you use
a Mercedes-Benz Service Centre for this
purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist work-
shop. X
Do not remove any foreign objects which
have penetrated the tyre, e.g. screws or
nails.
X Remove TIREFIT, the accompanying "max.
80 km/h "sticker and the electric air pump
from the stowage well underneath the lug-
gage compartment floor (Y page 254). 1
Driver's field of vision sticker
2 Wheel sticker
X Affix part 1of the sticker within the driv-
er's field of vision.
X Affix part 2of the sticker near the valve
on the wheel with the defective tyre. G
Risk of injury
TIREFIT must not come into contact with
your skin, eyes or clothing. R
If TIREFIT comes into contact with your
eyes or skin, immediately rinse thor-
oughly with clean water.
R Change out of clothing which has come
into contact with TIREFIT immediately.
R If an allergic reaction occurs, consult a
doctor immediately.
Keep TIREFIT away from children.
R If TIREFIT is swallowed, immediately
rinse your mouth out thoroughly with
water and drink plenty of water.
R Do not induce vomiting. Consult a doctor
immediately.
R Do not inhale TIREFIT fumes.
i If TIREFIT leaks out, allow it to dry. It can
then be removed like a layer of film.
If you get TIREFIT on your clothing, have it
cleaned as soon as possible with perchloro-
ethylene. G
Risk of injury
Comply with the manufacturer's safety
instructions shown on the sticker on the
electric air pump. Practical advice

X Remove the spare wheel from the exterior
bracket (Y page 256).
or
X Remove the "Minispare" emergency spare
wheel from the stowage compartment
under the luggage compartment floor
(Y page 256).
Raising the vehicle G
Risk of injury
The jack is designed only to raise the vehi-
cle for a short time while a wheel is being
changed.
If you intend to work under the vehicle, it
must be placed on stands.
Make sure that the jack is placed on a firm,
non-slip, level surface. Do not use wooden
blocks or similar items as jacking supports.
Otherwise, the jack will not be able to ach-
ieve its load-bearing capacity due to the
restricted height.
Do not start the engine at any time while
the wheel is being changed.
Do not lie under the vehicle when it is being
supported by the jack. If you do not raise the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the tailgate is opened or closed) and you
could be seriously injured.
G
Risk of accident
If you fail to position the jack correctly, the
vehicle may:
R slip off the jack
R injure you or others
R be damaged
It is thus important to ensure that the jack
is positioned correctly in the respective
jacking points. Before positioning the jack,
remove any dirt that may have collected in
the jacking points. 1
Wheel wrench X
Using wheel wrench 1, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts com-
pletely.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels (arrows). Practical advice
