At all times, occupants should sit
upright and be properly restrained
– infants and small children in appropri-
ate child-restraint systems; larger chil-
dren and adults using the safety belts.
Never let an occupant's head rest near
or on a side airbag because the inflating
airbag could cause a serious or fatal
injury. Please note that the word Airbag
imprinted on the door trim panel indi-
cates the airbag's location.
Accident research shows that the saf-
est place for children in an automobile
is in the rear seat. However, a child sit-
ting in the rear seat and not properly
restrained may place his or her head on
or near the side airbag, if so equipped.
For example, a child – even though
belted in – may fall asleep with his or
her head against the side airbag. It may
be difficult for a driver to ensure that
children in the rear seat will remain
properly positioned at all times and not
place their heads on or near the side
airbag. Therefore, we recommend that
the rear seat side airbags, if provided,
be deactivated if you plan to transport
children in the rear seat.
The rear seat side airbags may already
have been deactivated by a BMW cen-
ter. If you are uncertain of their status,
or wish to have the airbags activated or
deactivated, please contact your BMW
center.<
Even when all these guidelines are
observed, there is still a small residual
risk of injuries to the face, hands and
arms occurring from airbag deployment
in isolated instances.
In sensitive individuals, the ignition and
inflation noise may induce a mild hear-
ing loss that is temporary in most
cases.
Airbag warning information is also pro-
vided on the sun visors.This is the right way a child should sit in
a child restraint when rear side airbags
are provided.

This is the right way a larger child
should sit wearing the seat belt when
rear side airbags are provided.Indicator lamp
The indicator lamp indicates the
operational status of the airbag
system when the ignition key is
in position 1 or higher.
System operational:
>The indicator lamp comes on briefly
when the ignition key is turned to
position 1 or higher.
System malfunction:
>Indicator lamp does not come on or
>indicator lamp lights up continuously.
If there is a system malfunction,
there is a risk that the airbags will
not be triggered within their normal
response range, even if the level of
impact would normally have triggered
them. Have your BMW center inspect
the airbag system immediately.<

Starting the engine and driving off
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
drive off immediately at a moderate
engine speed.<
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.<
If the engine does not start on the first
attempt, such as when it is very hot or
cold:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures
below about +57/–156 and at high
altitudes above 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period, but no longer than
20 seconds.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged can damage the catalytic con-
verter.<
When driving, standing at idle or
parking the vehicle, take care to
avoid contact between the hot exhaust
system and flammable materials –
grass, hay, leaves, etc. Such contact
could lead to a fire, resulting in serious
personal injury and property damage.<

With the engine running, the gear
indicator in the SMG Drivelogic
display flashes to indicate that a driving
position is engaged with the driver's
door open or that the hood is not
closed properly, refer to page 68.
If neither the pedals, the shift paddles,
nor the selector lever are actuated, then
the gearbox is automatically taken out
of gear after approx. four seconds. It
will then be necessary to move the
selector lever back to position N before
engaging the desired driving position.
Driving off is not possible with the hood
open.<

Before exiting the vehicle with the
engine running, move the selector
lever into position N and apply the
parking brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharg-
ing, always deactivate electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.

Switching off the engine
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.<
Always engage the parking brake
when parking on downhill roads.
Engaging a gear may not sufficiently
secure the vehicle against rolling.<
Manual transmissionTurn the ignition key to position 1 or 0.Sequential M gearbox with
DrivelogicIf you turn the ignition key to position 1
or 0 with the selector lever in the for-
ward or reverse position, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in position
N, a warning tone and the flashing gear
indicator in the SMG Drivelogic display
remind you that no gear is engaged to
secure the vehicle against rolling.
The warning stops after approx.
10 seconds. If you move the selector
lever into a forward or reverse position
during this time, a gear is automatically
engaged.
Parking brakeThe parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates against the rear
wheels.To engageThe detent engages automatically, and
the indicator lamp in the instrument
cluster comes on when the ignition key
is in position 2, refer to page 18.To releasePull up slightly on the lever, press the
button and lower the lever.

If exceptional circumstances
make it necessary to engage the
parking brake while the vehicle is in
motion, do not pull it with excessive
pressure. Keep your thumb pressed
against the release button while care-
fully pulling the lever up.
Excessive pressure can lead to over-
braking and loss of traction – fishtailing
– at the rear axle.
The brake lamps do not come on when
the parking brake is engaged.
Always engage the parking brake when
parking on downhill roads. Engaging a
gear may not sufficiently secure the
vehicle against rolling.<
To avoid corrosion and one-sided
braking, apply the parking brake
from time to time when coasting to a
standstill – at a traffic light, for example
– provided that it is safe to do so.<
Manual transmission
When shifting gears in the 5th/6th
gear plane, be sure to press the
gearshift lever to the right in order to
prevent inadvertent selection of a gear
in the 3rd/4th gear plane. Do not hold
the vehicle in place on slopes by slip-
ping or 'riding' the clutch. Use the park-
ing brake instead. Riding the clutch
leads to severe and premature clutch
wear.<
ReverseSelect only when the vehicle is station-
ary. Press the shift lever to the left to
overcome the resistance.
As you do this, the backup lamps will
light up automatically when the ignition
key is in position 2.

Sequential M gearbox with Drivelogic*The conceptThe sequential M gearbox with
Drivelogic is an automated manual
gearbox with which clutching and shift-
ing is assumed by an electro-hydraulic
system.
The SMG Drivelogic is operated via two
shift paddles on the steering wheel and
the selector lever in the center console.
It offers the following functions:
>Sequential and automated shifting
mode
>Ability to choose between different
driving programs – Drivelogic
>Gradient assistance, refer to page 70
>Upshift display and shift lights, refer
to page 71
>RPM matching on downshifts
>Driving dependent functions:
The respective driving situation, e.g.
cornering, mountain driving or brak-
ing, is detected by sensors and taken
into account for shifting, e.g. to
achieve optimum gear selection dur-
ing deceleration and subsequent
acceleration
>Slip recognition at the rear axle for
increasing driving stability, e.g. dur-
ing downshifting on slippery road
surfaces>Operating safety through protection
against misshifting.
Under normal operating conditions, fuel
consumption is lowest when driving in
the first driving program of the auto-
mated shifting mode.
Selector lever positionsR: Reverse position
N: Neutral position
Forward position with one-touch mode:
>S: sequential mode
>D: automated mode
>+: upshifting in sequential mode
>–: downshifting in sequential mode.
The SMG Drivelogic is ready for opera-
tion from ignition key position two or
higher.
For your safety, it is only possible to
engage a driving position with the vehi-
cle stopped approx. two seconds after
engaging position 0 with the footbrake
depressed – shift-lock function.
