For all vehicles X
All occupants must get out of the vehicle.
Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area whilst a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Switch off the engine.
X Remove the key from the ignition lock.

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 as jacking supports. Oth-
erwise, the jack will not be able to achieve
its load-bearing capacity due to the restric-
ted 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 rais
e
the vehicle as described, it could slip off the
jack (e.g. if the engine is started or a door
or the boot lid are opened or closed) and
you could be seriously injured . 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 temperature s
down to -20 °C. G
Risk of accident
In the following situations, your safety is at
particular risk and TIREFIT is unable to pro -
vide 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 carr
y
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.

have penetrated the tyre, e.g. screws or
nails .
