2000 BMW 540I SEDAN lumbar support

50n
For maximum safety, please comply
with the following instructions when ad-
justing a seat:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with unexpected move-
ment, and the ensuing loss of vehicle
control could lead to an accident. Wear
the safety belt firmly against your body
at all times. In the event of a frontal im-
pact, a loose lap belt could slide over
your hips, leading to abdominal injury.
In addition, the safety belt's restraint ef-
fectiveness is reduced if the belt is
worn loosely.
Never ride with the backrest reclined to
an extreme horizontal angle (especially
important for front passengers to re-
member). Keep the backrest relatively
upright to minimize the risk of "sliding
under" the safety belt and sustaining in-
jury in an accident.
Do not slide the seats to the rear when
the vehicle is at an extreme angle (on
garage ramps or steep slopes, for in-
stance), to prevent the shoulder strap's
automatic height adjustment mecha-
nism from disengaging.<
1 Tilt angle (only driver's side)
2 Forward/Back adjustment
3 Cushion height
4 Backrest angle
5 Head restraint height
Adjust the tilt angle of the head restraint
by rotating it.
Comply with the adjustment
instructions in the preceding
column. Failure to do so could result in
diminished personal safety.< 380de023
Correct sitting postureTo reduce strain on the spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
The ideal sitting posture is achieved
with your head extending from your
spine in a straight line.
For long-distance driving, you may wish
to increase the backrest tilt-angle
slightly to reduce muscular tension.
Please remember that you should
always remain able to grasp the entire
periphery of the steering wheel without
straightening your arms.Lumbar support

This seat allows you to make additional
adjustments for:
1 Lumbar support
2 Shoulder supportLumbar supportYou can adjust the backrest's contour
for additional support in the curvature
of your spine's lumbar region.
The upper hips and spinal column re-
ceive supplementary support to help
you maintain a relaxed, upright posture.
>Press the front/rear of the switch:
Increase/decrease curvature.
>Press the upper/lower end of the
switch:
Increase the upper/lower curvature.380de024
Comply with the adjustment in-
structions on page 50. Failure to
do so could result in diminished per-
sonal safety.<
Shoulder supportYou can use the adjustable upper back-
rest for supplementary support in the
shoulder region. This provides a relaxed
driving position and helps relieve stress
on the shoulder muscles.
Press the rocker switch: The support
angle of the upper backrest section is
adjusted.
To obtain an optimal seating posture,
we recommend:
Driver and front passenger:
1 Adjust the upper backrest section
to its extreme rear position
2 Adjust to the optimal seating posture
as shown in the left column
3 Bring the upper backrest section for-
ward until your shoulders enjoy firm
support.380de064
