Sliding/Tilt sunroof
*
Other automatic operations are:
>With the sunroof open, press the
switch briefly toward "Lift:" The sun-
roof automatically extends to its fully
raised position
>With the sunroof lifted, press the
switch briefly toward "Open:" The
sunroof automatically opens all the
way.
Pressing the switch again briefly stops
the motion.Safety featureIf the sliding/tilt sunroof encounters re-
sistance at a point roughly past the
middle of its travel when it is closing,
the closing cycle is interrupted and the
sliding/tilt sunroof will open again
slightly.
Despite this safety feature, be ex-
tremely careful that the closing
path of the sunroof is not obstructed
whenever it is closed. Otherwise, trig-
gering the closing-force limitation may
not be ensured in some situations (with
very thin objects, for instance). You can
override this safety feature by pressing
the switch beyond the resistance point
and holding it.<
Sliding/Tilt sunroof with glass
moonroof
*
The options and control procedures are
essentially the same as those previ-
ously described for the sliding/tilt sun-
roof. In order to open the raised roof,
press the control switch towards
"Open" until the roof has reached the
desired position.
The headliner insert slides back some-
what when you raise the sunroof. When
the sunroof is opened the headliner
retracts with it. The headliner will then
automatically remain in its retracted
position, but can be repositioned as
desired.
Power loss or malfunctionAfter interruptions in the electrical
supply (when the battery is discon-
nected, for instance), the sunroof may
only lift. To reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all
the way
2 Press and hold the switch for
approximately twenty seconds.
In the event of an electrical malfunction,
you can also operate the sliding/tilt sun-
roof manually. Refer to page 180.390de637

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

BMW comfort seat

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

Front passenger's seat adjusted for
relaxed traveling:
1 Adjust the upper backrest section
to its extreme rear position
2 Increase the seat cushion tilt
3 Tilt the backrest more
4 Bring the upper backrest section
forward.
Make corrections in the forward-
backward adjustment of the seat
to ensure that the safety belt still fits
firmly against your body. If you do not
do this, the protection provided by the
safety belt may be reduced.<

Head restraintsTo adjust the angle of the front head
restraints: Adjust by tilting the head
restraint.
To adjust the height of the rear head
restraints: Adjust by pulling or applying
pressure.
Head restraints reduce the risk of
spinal injury in the event of an
accident. Adjust the head restraint so
that its center is approximately level
with your ears.
Leave the center-rear head restraint in
the fully-lowered position at all times,
since pulling it out limits its function.< 39mde051
Active changes in the seat's surface
help to avoid muscle cramps, pain in
the spine's lumbar region and fatigue.
To activate the seat, press the button
(arrow).
For additional details concerning the
BMW active seat, please refer to the
chapter describing "Advanced technol-
ogy" on page 190.390de629

Automatic steering wheel
adjustment (only in conjunction with seat, mirror
and steering wheel memory)
In order to make it easier to get into and
out of the car, the steering wheel auto-
matically moves into the top position
and returns to the driving (memory) po-
sition.
This automatic feature is controlled by
the position of the ignition key and by
the driver's door.

Mirrors
The mirror on the passenger's
side features a lens with a more
convex surface than the mirror installed
on the driver's side. When estimating
the distance between yourself and
other traffic, bear in mind that the ob-
jects reflected in the mirror are closer
than they appear. This means that esti-
mations of the distance to following
traffic should not be regarded as pre-
cise.<
Electric heatersBoth mirrors are heated automatically
with the ignition key in position 2.
Interior rearview mirrorTo reduce glare from vehicles behind
you after dark, tilt the mirror by moving
the small lever.Lighted vanity mirrorFold down the sun visor and slide the
cover panel to the side as required.
The mirror lamps operate in ignition key
positions 1 and 2.Sun visorsThese can be folded down toward the
windshield or swiveled out against the
side windows.390de030
Interior rearview mirror with
automatic dimming feature
*
By responding to the effects of ambient
light and the glare from following traffic,
this mirror automatically dims through
an infinitely-variable range.
The mirror automatically reverts to its
clear, undimmed setting whenever you
select "Reverse."
For proper functioning of the mirror, be
sure that the two photocells are unob-
structed and clean. One of the photo-
cells (arrow) is positioned in the mirror's
glass, while the other is slightly offset
on the opposite side of the mirror.

mic technology used in this mirror, refer
