Notes

Status at time of printing

BMW pursues a policy of continuous,
ongoing development that is conceived
to ensure that our vehicles continue to
embody the highest quality and safety
standards combined with advanced,
state-of-the-art technology. For this
reason, the features described in this
Owner's Manual could differ from those
on your vehicle. Nor can errors and
omissions be entirely ruled out. You are
therefore asked to appreciate that no
claims can be recognized on the basis
of the data, illustrations or descriptions
in this Owner's Manual.

For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight – that is,
15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent – will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality – volatility, composition, addi-
tives, etc. – among gasolines offered for
sale in the United States and Canada.
The use of poor quality fuels may result
in driveability, starting and stalling
problems especially under certain envi-
ronmental conditions, such as high
ambient temperature and high altitude.
Should you encounter driveability prob-
lems which you suspect could be
related to the fuel you are using, we
recommend that you respond by
switching to a recognized high-quality
brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Obey pertinent safety rules when you
are handling gasoline.

Starting 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
converter.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable materi-
als – grass, hay, leaves, etc. Such con-
tact could lead to a fire, resulting in
serious personal injury and property
damage.<

immediately when the engine starts
4. Engage a driving position
5. Release footbrake and slowly
depress accelerator pedal.
With the engine running, the gear
indicator in the SMG display
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 72.
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. Driving 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 park-
ing brake.
Never leave the vehicle unattended
with the engine running. An unat-
tended vehicle with a running engine
represents a safety hazard.<

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 SMG IIIf 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 0,
a warning tone and the flashing gear
indicator in the SMG display remind you
that the vehicle is not secured against
rolling.
The warning stops after approx. ten
seconds. If you move the selector lever
into a forward or reverse position dur-
ing 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 – see arrow – 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
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
When shifting gears in the
fifth/sixth gear plane, be sure to
press the gearshift lever to the right in
order to prevent inadvertent selection
of a gear in the third/fourth gear plane.
Do not hold the vehicle in place on
slopes by slipping or "riding" the clutch.
Use the parking brake instead. Riding
the clutch causes the clutch assembly
to wear out sooner.<
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.
