Adjusting

Seats
Note before adjusting
Never attempt to adjust your seat while
the vehicle is moving. The seat could
respond with unexpected movement, and the
ensuing loss of vehicle control could lead to an
accident.
Also on the passenger side, do not incline the
backrest too far to the rear while the vehicle is
being driven, otherwise there is a danger in the
event of an accident of sliding under the safety
belt, eliminating the protection normally pro-
vided by the belt.<
Please follow the instructions on damage to
safety belts provided on page53 and the infor-
mation on the active front head restraints
on
page51.
Adjusting seat
To ensure that the safety systems con-
tinue to provide optimized protection,
please observe the adjustment instructions on
page47.<

program. You can select from among three pro-
grams from comfort to sport.
