Changing wheels/tires
General information
When a flat tire kit is used, an immediate wheel
change when there is a tire pressure loss in the
event of a flat tire is not always necessary.
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
Warning
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 injury or danger to
life. When the vehicle is raised with the vehicle
jack, do not lie under the vehicle and do not
switch on the drive-ready state.
Warning
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 injury 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
When the vehicle jack is not inserted into the
jacking point provided for this purpose, the ve‐
hicle 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 in‐
serted in the jacking point next to the wheel
housing.
