Fine-link snow chains
Safety information
The manufacturer of the vehicle recommends
the use of fine-link snow chains. Certain types of
fine-link snow chains have been tested by the
manufacturer of the vehicle and recommended
as road-safe and suitable.
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.
Information regarding suitable snow chains is
available from a dealer’s service center or an‐
other qualified service center or repair shop.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:
DANGER
▷ 215/45 R 20.
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.
Follow the snow chain manufacturer's instruc‐
tions.
Do not reset the Tire Pressure Monitor TPM af‐
ter mounting snow chains, as doing so may re‐
sult in incorrect readings.
When driving with snow chains, activate the
Sport program with the selector lever. This en‐
sures that the rear wheels are being powered.
Warning
When driving with snow chains, briefly activate
Dynamic Traction Control DTC, if needed.
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.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains.
Changing wheels/tires
General information
When a flat tire kit is used, an immediate wheel
change when there is a loss of tire inflation pres‐
sure in the event of a flat tire is not always neces‐
sary.
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.
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.

Securing the vehicle against rolling
General information
The vehicle manufacturer recommends to addi‐
tionally secure the vehicle against rolling away
when changing a wheel.
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.
On a level surface
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.
Place chocks or other suitable objects, for exam‐
ple a rock, in front of and behind the wheel that is
diagonally opposite to the wheel that you wish to
change.
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.
On a slight downhill gradient
Warning
Incorrect handling of the vehicle jack can dam‐
age the vehicle's underbody and expose high-
voltage components. 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. Make
sure not to damage any of the underbody pan‐
eling parts.
If you need to change a wheel on a slight down‐
hill grade, place chocks and other suitable ob‐
jects, for instance a rock, under the wheels of
both the front and rear axles against the rolling
direction.
