Maximum speed of winter tires
Repairing a flat tire
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then attach a label showing the permissible maxi‐
mum speed in the field of view. The label is avail‐
able from a dealer's service center or another
qualified service center or repair shop.
Safety measures
▷ Park the vehicle as far away as possible from
passing traffic and on solid ground.
▷ Switch on the hazard warning system.
With winter tires mounted, observe and do not
exceed the permissible maximum speed.
▷ Secure the vehicle against rolling away by
setting the parking brake.
▷ Turn the steering wheel until the front wheels
are in the straight-ahead position and engage
the steering wheel lock.
Rotating wheels between axles
▷ Have all vehicle occupants get out of the ve‐
hicle and ensure that they remain outside the
immediate area in a safe place, such as be‐
hind a guardrail.
Warning
Rotating tires between the axles on vehicles
with different tire sizes or rim sizes on the front
and rear axles can cause damage to the tires
and the vehicle. There is a risk of accident. Do
not rotate the tires between the axles on vehi‐
cles with different tire sizes or rim sizes on the
front and rear axles.
▷ If necessary, set up a warning triangle at an
appropriate distance.
Snow chains
Safety information
Warning
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated in pairs be‐
tween the axles to achieve even wear. Further in‐
formation is available from a dealer's service cen‐
ter or another qualified service center or repair
shop. After rotating, check the tire pressure and
correct, if needed.
With the mounting of snow chains on unsuita‐
ble tires, the snow chains can come into con‐
tact with vehicle parts. There may be a risk of
accident or risk of damage to property. Only
mount snow chains on tires that are designated
by their manufacturer as suitable for the use of
snow chains.
Storing tires
Tire inflation pressure
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Warning
Storage
Insufficiently tight snow chains may damage
tires and vehicle components. There may be a
risk of accident or risk of damage to property.
Make sure that the snow chains are always suf‐
ficiently tight. Re-tighten as needed according
to the snow chain manufacturer's instructions.
Store wheels and tires in a cool, dry and dark
place.
Always protect tires against all contact with oil,
grease, and solvents.
Do not leave tires in plastic bags.

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.
