only be made when the vehicle is
stationary.
Before taking to the road and to make the most
of the ergonomic layout of the instruments and
controls, carry out these adjustments in the
following order:
–

head restraint height.
–


seat backrest angle.
–


seat cushion height.
–


longitudinal seat position.
–


steering wheel height and reach.
–


rear view mirror and door mirrors.

Once these adjustments have been
made, check that the instrument panel
can be viewed correctly from your driving
position.

perception of heat is impaired (e.g.
illness,
taking medication).
To keep the heated pad intact and to prevent
