AirbagsThe rear seat side airbags may already
have been deactivated, either at the
time of manufacture or by a BMW
center. Labels in the rear door opening
should indicate the status of your rear
seat side airbags. 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
followed, there is still a small residual
risk of injuries to the face, hands and
arms occurring from airbag deployment
in isolated instances. The ignition and
inflation noise may provoke a mild
temporary hearing loss in extremely
sensitive individuals.
Airbag warning information is also
provided on the sun visors. This is the right way a child should sit in
a child-restraint device when rear side
airbags (arrow) are provided.
This is the right way a larger child
should sit wearing the safety belt when
rear side airbags (arrow) are provided.

Airbags Transporting children safelyOperational status
The indicator lamp in the instru-
ment cluster displays the opera-
tional status of the airbag
system from ignition key position 1.
System operational:
>The indicator lamp comes on briefly
when you turn the ignition key to
position 1 or higher.
System malfunction:
>The indicator lamp fails to come on,
when the ignition key is turned
>The indicator lamp fails to go out
after the engine has been started, or
it comes on during normal driving.
Please respond to any malfunctions in
the system by immediately having it
inspected at your BMW center; other-
wise the airbag could fail to respond to
an accident in which both the angle and
the severity of the impact would
normally trigger airbag deployment.
Commercially available child-restraint
systems are designed to be secured
with a lap belt or with the lap belt
portion of a combination lap/shoulder
belt. Improperly or inadequately
installed restraint systems can increase
the risk of injury to children. Always
read and follow the instructions that
come with the system.
If you use a child-restraint system with
a tether strap, three additional tether
anchorage points have been provided
(refer to the arrows in the illustration).
Depending on the location selected for
seating in the rear passenger area,
attach the strap hook to the corre-
sponding anchorage point to secure the
child-restraint system. Remove the
cover first on the middle location.
If the respective seating position is
fitted with a head restraint lift the head
restraint and pass the tether strap
between the head restraint and the seat
back.
Adjust the tether strap according to the
child-restraint manufacturer's instruc-
tions.

has been opened.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition (ignition key in position 0
or key removed). Simply switch it back
on.Steering unlocked You will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation. 1. Engage the parking brake
2. Gearshift lever in idling position
3. Press the clutch pedal at low
temperatures
4. Start the engine. Do not press the
accelerator pedal. Do not actuate the
starter for too short a time. Do not
turn it for more than approx.
20 seconds. Release the ignition key
immediately when the engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, begin
driving immediately at a moderate
engine speed.

SMG II: refer to the instructions on
page 60.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas.
Breathing the exhaust gases poses an
extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a potential safety hazard.<

Starting the engine Switching off the engine If the engine does not start on the first
attempt (the engine is very hot or cold,
for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
starting at about +57 (Ð156) and at
high altitudes over 3,300 ft (over
1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to damage to the
catalytic converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in personal injury
and property damage.<
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
discharging, always switch off electrical
devices that are not in use. Switch the
ignition off when the vehicle is not
being driven.Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving.
If you did so, the steering lock would
engage when the steering wheel is
turned.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
or reverse gear may not be enough to
prevent it from rolling away.<

Parking brake Manual transmission The parking brake is primarily designed
to prevent the vehicle from rolling while
parked. It operates against the rear
wheels. To engageThe lever engages automatically, 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 (arrow) and lower the lever.
If, in exceptional circumstances, it
should be 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 to apply
moderate pressure.
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.
Set the parking brake when parking on
steep hills, because under certain
conditions, putting the vehicle into first
or reverse gear may not be enough to
prevent it from rolling away.<
To avoid corrosion and one-sided
braking, apply the parking brake lightly
from time to time when coasting to a
standstill (at a traffic signal, for
instance), provided that it is safe to do
so.
Press the clutch pedal all the way down
each time you shift, pressing the
manual gearshift lever into its proper
end position.
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.<

indicator in the instrument cluster
flashes to indicate that a driving posi-
tion is engaged with the driver's door
open or if the hood is not closed prop-
erly, refer to page 61.
If none of the pedals is actuated, then
the gearbox is automatically taken out
of gear after approx. 4 seconds.
Then the desired direction of travel
must be selected again with the
selector lever in position 0.<
Starting off is not possible with the
hood open.<
Before exiting the vehicle with the
engine running, move the selector
lever into position 0 and apply the
parking brake.
Never leave the vehicle unattended

Cruise control You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
The cruise control is available whenever
the engine is running and the system
has been activated.
To activate the systemFrom ignition key position 2:
Press the button and the indicator lamp
in the instrument cluster (refer to
page 20) will come on. You can now
use the cruise control.
Do not use cruise control on
twisting roads, when high traffic
density prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice), or when the road
surface is loose (rocks or gravel,
sand).<To deactivate the systemPress the button as often as you need
to until the indicator lamp in the instru-
ment cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.
To maintain and store speed
or to acceleratePress button (+) briefly:
The system maintains and stores the
current vehicle speed. Every time you
tap the button, the speed increases by
0.6 mph (1 km/h).
Press and hold button (+):
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
maintains and stores the current speed.
If, on a downhill gradient, the
engine's braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
