Roof racks are available as special accessories.
Securing
Follow the installation instructions of the roof
rack.
Loading
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect
on vehicle handling and steering response.
Therefore, note the following when loading and
driving:
▷Do not exceed the approved roof/axle
loads and the approved gross vehicle
weight.
▷Be sure that adequate clearance is main‐
tained for tilting and opening the glass sun‐
roof.
▷Distribute the roof load uniformly.▷The roof load should not extend past the
loading area.
▷Always place the heaviest pieces on the
bottom.
▷Secure the roof luggage firmly, e.g., tie with
ratchet straps.
▷Drive cautiously and avoid sudden acceler‐
ation and braking maneuvers. Take corners
gently.

Winter tires
Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires provide
better winter traction than summer tires, they
do not provide the same level of performance
as winter tires.
Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then a respective symbol is displayed in your
field of vision. The label is available from a
dealer’s service center or another qualified
service center or repair shop.
With mounted winter tires, observe and adhere
to the permissible maximum speed.
Run-flat tires
If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Further information is availa‐
ble from a dealer’s service center or another
qualified service center or repair shop.
Rotating wheels between axles
Different wear patterns can occur on the front
and rear axles depending on individual driving
conditions. The tires can be rotated between
the axles to achieve even wear. Further infor‐
mation 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.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.
Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of tires that are self-
supporting to a limited degree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the
event of a tire inflation pressure loss.
Continued driving with a damaged tire, refer to
page 109.
Continued driving with a damaged tire, refer to
page 106.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire.
A dealer’s service center will be glad to answer
additional questions at any time.
