Changing wheels/tires
General information
When using run-flat tires or a flat tire kit, a wheel
does not always need to be changed immedi‐
ately when there is a loss of tire inflation pressure
due to a flat tire.
If needed, the tools for changing wheels are
available as accessories from a dealer’s service
center or another qualified service center or re‐
pair shop.
Safety information
DANGER
The vehicle jack is only provided for short-term
lifting of the vehicle for wheel changes. Even if
all safety measures are observed, there is a risk
of the raised vehicle falling, if the vehicle jack
tips over. There is a risk of injuries or danger to
life. If the vehicle is raised, do not lie under the
vehicle and do not start the engine.
DANGER
Supports such as wooden blocks under the ve‐
hicle jack reduce the capacity of the vehicle
jack to bear weight. They have the potential to
exert too much strain on the vehicle jack, caus‐
ing it to tip over and the vehicle to fall. There is
a risk of injuries or danger to life. Do not place
supports under the vehicle jack.
Warning
The jack, issued by the vehicle manufacturer, is
provided in order to perform a wheel change in
the event of a breakdown. The jack is not de‐
signed for frequent use; for example, changing
from summer to winter tires. Using the jack fre‐
quently may cause it to become jammed or
damaged. There is a risk of injury and risk of
damage to property. Only use the jack to attach
an emergency or spare wheel in the event of a
breakdown.
Warning
On soft, uneven or slippery ground, for example
snow, ice, tiles, etc., the vehicle jack can slip
away. There is a risk of injury. If possible,
change the wheel on a flat, solid, and slip-re‐
sistant surface.
Warning
The vehicle jack is optimized for lifting the vehi‐
cle and for the jacking points on the vehicle
only. There is a risk of injury. Do not lift any
other vehicle or cargo using the vehicle jack.
Warning
If the vehicle jack is not inserted into the jacking
point provided for this purpose, the vehicle may
be damaged or the vehicle jack may slip when
it is being cranked up. There is a risk of injury or
risk of damage to property. When cranking up
the vehicle jack, ensure that it is inserted in the
jacking point next to the wheel housing.
Warning
A vehicle that is raised on a vehicle jack may fall
off of the jack if lateral forces are exerted on it.
There is a risk of injury and risk of damage to
property. While the vehicle is raised, do not ex‐
ert lateral forces on the vehicle or pull abruptly
on the vehicle. Have a stuck wheel removed by
a dealer’s service center or another qualified
service center or repair shop.
