Before installing any child-
restraint device or child seat,
please read the following:
Never install a rearward-facing child-
restraint system in the front passenger
seat of this vehicle.
Your vehicle is equipped with an airbag
supplemental restraint system for the
front passenger. Because the backrest
on any rearward-facing child-restraint
system – of the kind designed for
infants under 1 year and 20 lbs/9 kg –
would be within the airbag's deploy-
ment range, you should never mount
such a device in the front passenger
seat, since the impact of the airbag
against the child-restraint's backrest
could lead to serious or fatal injuries.
If it is necessary for a child – not an
infant – to ride in the front seat, certain
precautions should be taken. First,
move the passenger seat as far away
from the dashboard as possible. This
important precaution is intended to
maximize the distance between the air-
bag and the child. Older children
should be tightly secured with a safety
belt after they have outgrown a booster
seat that is appropriate for their age,
height, and weight. Younger children
should be secured in an appropriate
forward-facing child-restraint system
that has first been properly installed
with a safety belt.
Never install a rearward-facing child-
restraint system in the front passenger
seat.
We strongly urge you to carefully read
and comply with the instructions for
installation and use provided by the
child-restraint's manufacturer whenever
you use such a device.
Do not attempt to modify child-restraint
systems. If you do this, the protection
provided by these systems could be
impaired.
Always ensure that all occupants – of all
ages – remain properly and securely
restrained at all times.<
All rear seating positions in your vehicle
meet the recommendations of
SAE J1819, an industry-recommended
practice for securing child-restraint sys-
tems in motor vehicles.
Securing child-restraint systemAll of the rear belt retractors and the
front passenger's safety belt can be
locked for mounting and securing child-
restraint systems.
A label with the appropriate instructions
for this is located in the immediate
vicinity of the buckle latch of each
safety belt.To lock the safety beltExtract the entire length of the belt from
the inertia reel mechanism. Allow the
reel to retract the belt somewhat and
engage the buckle, then tighten the belt
against the child-restraint system. The
retraction mechanism is now locked.

Always observe the installation instruc-
tions provided by the manufacturer of
the child-restraint system.To unlock the safety beltRelease the safety belt, remove the
child seat and retract the safety belt to
its end position on the belt retractor.
LATCH child-restraint mounting
systemLATCH: Lower Anchors and Tethers for
CHildren
The left and right rear seats are both
equipped with a LATCH child-restraint
mounting system.
Canadian models only:
The LATCH anchorage points are iden-
tified by buttons.
Remove the cover from the outside
mount by pulling forward. When rein-
stalling ensure that the recess is on the
top.

restraint mounting system at the right
rear seat.
Always follow all manufacturer's
instructions and observe all safety
precautions when installing the LATCH
child-restraint mounting system.<

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYou can learn about the entire array of
features this system offers at your BMW
center.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your vehi-
cle, refer to pages 33, 36
>Activating/deactivating the 'Follow
me home' function, refer to page 94
>Activating/deactivating daytime driv-
ing lamps, refer to page 94

Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 or removed until
the selector lever is in position P.<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.Steering unlockedYou 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.
Starting the engine
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.
When driving, standing at idle or park-
ing the vehicle, take care to avoid con-
tact 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.<
Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.<

If the engine does not start on the first
attempt – if it is very hot or cold, for
instance:
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures below approx. +57/–156 and at
altitudes over 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
>Press the accelerator pedal halfway
down while engaging the starter.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<
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.Manual transmission1. Engage the parking brake

the selector lever to position P and
engage the parking brake before leav-
ing your vehicle with the engine run-
ning.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a safety hazard. 2. Place the selector lever in neutral

The gearbox is automatically taken out
of gear if the driver's door is opened
while the engine is running and the
driver does not actuate the pedals, the
shift paddles or the selector lever. This
is accompanied by a warning tone and
the flashing gear indicator. The gear
display N appears in the instrument-
cluster.<
Before exiting the vehicle with the
engine running, move the selector

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.<

and turn the ignition key to position 1 or
0.SMG gearboxIf you turn the ignition key to position 1
or 0 with the selector lever in position
R, or in sequential mode, a gear auto-
matically remains engaged.
If you turn the ignition key to position 1
or 0 with the selector lever in neutral
position N, a warning tone and the
flashing gear indicator in the display
remind you that no gear is engaged to
secure the vehicle against rolling.
The warning stops after approx.
9 seconds.
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.
Vehicles with manual or SMG gearbox:
Engage the parking brake when parking
on downhill roads, since engaging a
gear may not provide adequate resis-
tance to rolling, not even in first or
reverse gear.
Vehicles with automatic transmission:
place the selector lever in P.<
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
example – provided that it is safe to do
so.<
Manual transmission
Do not hold the vehicle in place on
slopes by slipping or 'riding' the
clutch. Use the parking brake instead.
Riding the clutch leads to severe and
premature clutch wear.<
6-speed transmission*When changing gear in the 5th/6th gear
plane, be sure to press the gearshift
lever to the right to prevent inadvert-
ently shifting to a gear of the 3rd/4th
gear plane.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 manual gearbox SMG*The conceptThe sequential manual gearbox SMG is
an automated manual gearbox with
which clutching and shifting is assumed
by an electro-hydraulic system.
The SMG is operated via the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Sequential mode: manual mode
>Drive mode: automatic operation
>Ability to choose between two differ-
ent driving programs: Standard,
Sport
>Operating safety through protection
against misshifting
>Automatic upshifts and downshifts in
the drive mode
>Automatic downshifts at minimum
engine rpm
>Kickdown function in the drive mode.
>Acceleration assistant, refer to
page 72.
Selector lever positionsThe current selector lever position is
indicated by a light-emitting diode in
the center console.
R: Reverse
N: Neutral
Position for forward driving with one-
touch functions:
Sequential mode
+: manual upshifts
—: manual downshifts
D: drive mode.
The SMG is ready for operation in igni-
tion key position 2.
The gearbox is automatically
placed in neutral gear if the
driver's door is opened while the engine
is running and the driver does not actu-
ate the pedals, the shift paddles or the
selector lever.
This is accompanied by an acoustic
signal and the flashing gear indicator.
The gear display N appears in the
instrument cluster.
A driving position can only be engaged
when the driver's door is closed.
When the vehicle is unlocked, a buzzer
in the area of the transmission indicates
that the system is ready for operation.<
ShiftlockWhen the car is at a standstill, a safety
function requires you to depress the
brake pedal if you want to move the
selector lever from the neutral
position N to a driving position.Driving precautions
Use enough acceleration to pull
away speedily when moving off on
an uphill gradient. Never try to prevent
the car from rolling back on an uphill
gradient by depressing the accelerator
pedal; always apply the handbrake.
Otherwise you could overheat the SMG
gearbox.<

RReverseSelect only when the vehicle is station-
ary.NNeutralAlways engage before starting the
engine, refer to Starting the engine on
page 66.Sequential modeEach time the engine is started, the
sequential mode is activated as soon as
you move the selector lever into the for-
ward driving position while the brake is
depressed.
The gears are shifted via the shift pad-
dles or the selector lever.
It is also possible to drive off in second
gear, e.g. on snow-covered roads.DDrive modeIn the drive mode all forward gears are
shifted automatically.
To switch from sequential to drive
mode: tap the selector lever to the right
toward D.
For rapid acceleration, e.g. during
passing, depress the accelerator pedal
completely: kickdown.To switch back to sequential mode: tap
the selector lever again to the right
toward D or change the current gear via
the shift paddles or the selector lever.
KickdownYou can achieve maximum acceleration
using kickdown.
Depress the accelerator pedal past the
increased resistance point at the full-
throttle position.
Shifting gearsWith selector lever:
>To upshift, tap the selector lever
toward +
>To downshift, tap the lever toward —.
With shift paddles on steering wheel:
>To upshift, pull one of the shift pad-
dles
>To downshift, push the paddle.
You accelerate from higher gears, e.g.
during passing, by manually downshift-
ing.
In the following situations, the SMG in
the sequential mode assists you:
>The transmission will only execute
upshifts and downshifts that will
result in an appropriate combination
of vehicle speed and engine rpm. For
