Sliding/Tilt sunroofAutomatic
* opening and closing
Press the switch past the resistance
point briefly: The sunroof travels to ei-
ther the fully-closed or fully-open posi-
tion.
Other automatic operations are:
>With the sunroof open, press the
switch briefly toward "Lift:"
The sunroof 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 immediately.
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 roof. When the
roof is opened, the headliner retracts
with it. The headliner will then automati-
cally remain in its retracted position, but
can be repositioned as desired.
Power loss or malfunctionAfter interruptions in electrical supply
(when the battery is disconnected, for
instance), the sunroof will only lift. To
reinitialize the mechanism:
1 Raise the sliding/tilt sunroof all the
way
2 Continue to hold the switch for
approx. five seconds.
In the event of an electrical system mal-
function, the sliding/tilt sunroof can be
manually operated. Refer to page 178.380de616

Cargo loading Roof-mounted luggage rack
*
Securing the load>Secure smaller, light pieces with the
retaining straps or with a luggage
compartment net or elastic straps (re-
fer to page 39)
>For large, heavy pieces, see your
BMW center for load-securing de-
vices
*. Lashing eyes are provided at
the corners of the luggage compart-
ment for attaching these load-secur-
ing devices (refer to the illustration).
>Comply with the information en-
closed with the load-securing de-
vices.
380de613
Always position and secure the
load correctly, otherwise it can en-
danger the passengers in the event of
braking, swerving or in a crash.
Do not exceed the permissible gross
weight and the permissible axle loads
(refer to page 196). If you do so, the
operating safety of the vehicle is no
longer ensured, and you are in violation
of the law.
Do not stow heavy or hard objects in
the passenger compartment unless
they are properly secured. Improperly
secured objects would be thrown
around during braking and evasive ma-
neuvers and endanger the occupants.<
A special luggage system is available as
an option for your BMW. Please comply
with the precautions included with the
installation instructions.
Because roof racks raise the center of
gravity of the car when loaded, they ex-
ercise a major effect on its handling and
steering response.
You should therefore always remember
not to exceed the approved roof weight,
the approved gross vehicle weight or
the axle weights when loading the rack.
You will find the specifications under
"Technical Data" on page 196.
Make sure that the load is not too
heavy, and attempt to distribute it
evenly. Always load the heaviest pieces
first (on the bottom). Make sure there is
sufficient space to raise the sliding/tilt
sunroof.
