Raising and closing glass roof
Ignition key as of position 1:
>Briefly press the switch for raising the
roof:
The roof opens and the sliding panel
moves back approx. 2 in/5 cm
>Press the switch twice beyond the
resistance point toward the rear:
The roof opens and the sliding panel
moves completely back
>To close, briefly press the switch or
push it twice beyond the resistance
point toward the front:
The roof and sliding panel close.
Opening and closing sliding panel
Ignition key as of position 1:
>Push the switch up to the resistance
point in the desired direction:
The sliding panel continues to move as
long as you continue to hold the switch
>Push the switch beyond the resistance
point in the desired direction:
The sliding panel moves automatically.
Briefly press the switch again in any
direction to stop the movement.
After switching off ignition
You can still operate the roof:
>Ignition key in position 1 for approx.
15 minutes
>In position 0 or with the ignition key
removed for approx. 1 minute, as long
as a door has not been opened.
For information on using the convenience
operation mode at the door lock or with the
remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the glass roof encounters resistance
when closing from the raised position, the
closing action is interrupted and the glass
roof opens.
If the sliding panel encounters resistance
when closing within approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens approx. 8 in/20 cm.
Despite the anti-trapping mechanism,
you should always inspect the roof's
travel range prior to closing it, as the safety
feature might fail to detect certain kinds of
obstructions, such as very thin objects, and
the roof would continue closing.
The anti-trapping mechanism for closing
the glass roof is deactivated if the switch is
pressed beyond the resistance point and
held there. The closing action is immedi-
ately interrupted when you release the
switch.<
Following interruptions in electrical
power supply
After disconnecting the battery, it can
occur that the glass roof does not move.
The system has to be initialized. Should
this occur, please have the roof initialized
at your BMW center.
Manual operation
In the event of an electrical malfunction,
you can operate the panorama glass roof
and the sliding panel manually.

Adjustments
Sitting safely
The ideal sitting position can make a vital
contribution to relaxed, fatigue-free driving.
The sitting position also plays an important
role together with the safety belts and air-
bags in providing occupants with maximum
levels of passive safety in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the
following section.
For additional information on transporting
children safely, refer to page 51.
Sitting safely with airbags
Always maintain an adequate dis-
tance between yourself and the air-
bags. Always hold the steering wheel by
its rim with hands at the 9 o'clock and
3 o'clock positions, to minimize the risk of
injuries to your hands and arms in the event
of airbag deployment.
No one and nothing is to come between the
airbags and the seat occupant.
Do not use the cover of the front airbag on
the front passenger side as a storage area.
Make sure that the front passenger is sit-
ting correctly and does not rest feet or legs
on the instrument panel, otherwise leg inju-
ries can occur if the knee and front airbags
are triggered.
Never let an occupant's head rest near or
on a side airbag because the inflating air-
bag could cause a serious or fatal injury.<
Even if you adhere to all the instructions
injuries resulting from contact with airbags
cannot be fully excluded, depending on the
circumstances. The ignition and inflation
noise may provoke a mild – usually tempo-
rary – hearing loss in extremely sensitive
individuals.
For airbag locations and additional infor-
mation on airbags, refer to page 81.
Sitting safely with safety belts
Fasten your safety belt before starting any
trip. Airbags complement the safety belt as
an additional safety device, but they do not
represent a substitute.
Your vehicle has four seats that are all
equipped with a safety belt.
At all times, occupants should sit
upright and be properly restrained:
infants and small children in appropriate
child-restraint systems; larger children and
adults using the safety belts.
Never allow more than one person to wear
a single safety belt. Never allow infants or
small children to ride in a passenger's lap.
Expectant mothers should always wear
their safety belts, taking care to position
the lap belt against the lower hips, where it
will not exert pressure against the abdomi-
nal area.
Do not route the belt across your neck, or
run it across sharp edges. Be sure that the
belt does not become caught or jammed.
Avoid twisting the belt while routing it firmly
across the hips and shoulder. Do not allow
the belt to rest against hard or fragile
objects. Otherwise, in the event of a frontal
impact, a loose lap belt could slide over
your hips, leading to abdominal injury.
Avoid wearing clothing that prevents the
belt from fitting properly and pull the lap
belt periodically to readjust the tension
across your shoulder in order to avoid a
reduction in the retention effect of the
safety belt.<
For instructions on operating safety belts,
refer to page 47.

matic curb monitor, refer to page 45
To prevent the exterior mirrors from
being damaged due to the width of
the vehicle, always fold them in by hand
before entering an automatic car wash.<
You can also adjust the mirrors manually
if necessary by pressing against the outer
edges of their lenses.
Storing the mirror positions, refer to Seat,
mirror and steering wheel memory,
page 44.
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 objects reflected in the mirror
are closer than they appear. This means
that estimations of the distance to following
traffic should not be regarded as precise.<
Automatic functions
>Both exterior mirrors are automatically
heated in ignition key position 2
>The interior and exterior mirrors dim
depending on the light occurring when
the vehicle is being driven forward
*.There are two photocells in the interior
mirror to control the automatic dimming
of the interior mirror. One is integrated
within the mirror's lens, refer to arrow,
while the other is located at an offset
position on the rear of the mirror hous-
ing.
For trouble-free operation, keep the
photocells clean and do not cover the
area between the interior rearview mir-
ror and the windshield. Do not attach
any kind of stickers on the windshield in
front of the mirror, either.

3 Start engine
Starting engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas.Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.
To prevent the vehicle from rolling, always
select idle position or position N and apply
the handbrake before leaving the vehicle
with the engine running.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
Special starting conditions
Press the accelerator pedal halfway down
when starting if
>the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>the engine is started at very low tem-
peratures, below approx. + 57/–156,
at high altitudes, over 3,300 ft/1,000 m.
Avoid frequent starting in quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter.<
Manual transmission
1.Apply the handbrake
2.Gearshift lever in idle position
3.Press the clutch pedal
If the clutch pedal is not
depressed, the engine will not
start.<
4.Start the engine.
Do not terminate the starting operation
too early, but after approx. 20 seconds
at the latest. When the engine starts, let
go of the ignition key immediately.
