DRIVING TIPS
Dynamic Stability Control when driving with
roof load.
Roof drip rail with flaps
The fixing points are located in the roof drip rail
above the doors.
Fold the cover outward.
Mounting
Follow the installation instructions of the roof
rack.
Be sure that adequate clearance is maintained
for tilting and opening the glass sunroof.
Loading
Because roof-mounted luggage 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 bot‐
tom.

▷ Secure the roof luggage firmly, for instance
using ratchet straps.

Driving on racetracks
Warning
The vehicle is not designed for use in M Sport
or motor sport type competition. There is a risk
of accident. Do not use the vehicle for M Sport
or motor sport type competitions.
Higher mechanical and thermal loads during
racetrack operation lead to increased wear. This
wear is not covered by the warranty.
When driving on a racetrack, increase the dura‐
tion of the load slowly.
The standard brake linings and the wear indica‐
tors are not designed for racetrack operation.
