Wheel change
General
For run-flat tyres or when using a flat tyre kit, it is
not always necessary to change a wheel immedi‐
ately if tyre inflation pressure is lost due to a flat
tyre.
If required, the tools for changing wheels are
available as optional accessories from a Service
Partner of the manufacturer, another qualified
Service Partner or a specialist workshop.
Safety notes
DANGER
The jack is only intended for raising the vehicle
briefly during a wheel change. Even if the safety
measures are complied with, there is a risk of
the raised vehicle falling over due to the jack
slipping. There is a danger of injury or even
death. If the vehicle is raised with the jack, do
not lie underneath the vehicle and do not start
the engine.
DANGER
Supports such as wooden blocks under the ve‐
hicle jack can prevent it from achieving its load
capacity due to the restricted height. The load
capacity of the wooden blocks may be excee‐
ded, causing the vehicle to tip over. There is a
danger of injury or even death. 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 tyres. Using the jack
frequently may cause it to become jammed or
damaged. There is a danger of injury and dam‐
age to property. Only use the jack to change an
emergency wheel or a spare wheel in the event
of a flat tyre.
WARNING
On soft, uneven or slippery ground, for exam‐
ple, snow, ice, tiles or similar, the jack may slip.
There is a danger of injury. Perform the wheel
change on a level, firm and non-slip surface if at
all possible.
WARNING
The jack is only optimised for raising the vehi‐
cle and for use with the jacking points on the
vehicle. There is a danger of injury. Do not lift
another vehicle or other items with the jack.
