dure is complete.

mised acceleration values may be reached
again only after a few minutes.
Notes on driving
& WARNING Risk of accident due to
objects in the driver's footwell
Objects in the driver's footwell may impede
pedal travel or block a depressed pedal.
This jeopardises the operating and road
safety of the vehicle.
Stow all objects in the vehicle securely
#
so that they cannot get into the driver's
footwell.
Always fit the floor mats securely and
#
as prescribed in order to ensure that
there is always sufficient room for the
pedals.
Do not use loose floor mats and do not
#
place floor mats on top of one another.
