the strap which is fastened to the cap.
A loose or missing cap will activate the
CHECK GAS CAP* lamp.<
Warning lamp* lights up. The
gas cap is not properly closed
or is missing. Check if the gas
cap is properly closed.Fuel tank capacity>Approx. 16.6 gal./63 liters, of which
>approx. 2.1 gal./8 liters are reserve
capacity.
Do not drive to the last drop of
fuel. This can prevent the engine
from operating properly and result in
damage.<
Fuel specificationsThe engine uses lead-free gasoline
only.Required fuelPremium Unleaded Gasoline,
Minimum Octane Rating: AKI 91.
Minimum Octane Rating corresponds to
the Anti Knock Index AKI and is deter-
mined according to the so-called
(R+M)/2 method.
Do not use leaded gasoline, as
otherwise the lambda probe and
catalytic converter will be permanently
damaged. cant differences in fuel quality: volatility,
composition, additives, etc., among
gasolines offered for sale in the United
States and Canada. 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 % meth-
anol plus an equivalent amount of co-
solvent, will not void the applicable
warranties with respect to defects in
materials or workmanship.
The use of poor-quality fuels may
result in drivability, starting and
stalling problems especially under cer-
tain environmental conditions such as
high ambient temperature and high alti-
tude.
Should you encounter drivability 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 also result in unsched-
uled maintenance.<

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 you leave the vehicle with the engine
running, move the gearshift lever into
the idling position or the selector lever
into position N, as applicable, and
apply the parking brake. If you fail to do
this, the vehicle could move.<
>Do not press the accelerator pedal
while starting the engine
>Do not end the starting procedure too
early, but do not continue it for more
than 20 seconds
>Release the ignition key immediately
when the engine starts
>Do not let the engine warm up in
idling position. Instead, begin to drive
at moderate engine speeds.
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 very low temperatures
below about +5 7/–156 and at high
altitudes above 3,300 ft/1,000 m:
>On the first attempt, engage the
starter for approx. 10 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.<
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.<

132Laws and regulations
OBD interface socketThe Onboard Diagnostic OBD interface
socket is located on the left of the
driver's side under the instrument panel
and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle"s
lifetime. The system monitors emission-
related components and systems for
deterioriation and malfunction.
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Display in Canadian models for
the malfunction described
above.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission control
components, especially the catalytic
converter.
When the fuel filler cap is not
properly tightened, the OBD sys-
tem can detect the vapor leak and the
indicator will light up. If the filler cap is
subsequently tightened, the indicator
should go out within a few days.<
Event data recordersYour vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agreement
for the BMW Assist system, certain
vehicle information may be transmitted
or recorded in order to provide such
services.

If the tow bar can only be used in a
diagonal position, please note the fol-
lowing:
>Clearance is restricted while you are
driving around corners
>The inclination of the tow bar pro-
duces lateral force.
Only attach the tow bar to the
towing eyelets. Other parts of the
vehicles could otherwise be dam-
aged. make sure that the tow rope is taut.
Use nylon ropes or straps for tow-
ing because they prevent sudden
jerking movements. Attach the tow rope
only to the towing eyelets. Other parts
of the vehicles could otherwise be
damaged.<
With a tow truckHave the BMW transported by a tow
truck with a lift sling, or on a flatbed.
Never allow passengers to ride in
a towed vehicle for any reason.<
Do not lift the vehicle by the tow-
ing eyelet, nor by parts of the
body or chassis. Otherwise damage
could result. converters if the engine is cold. It is
better to jump-start the engine, refer to
page 147.

5. Pull over at a suitable location,
remove the tow bar or tow rope, and
turn on the hazard warning flashers
6. Have the vehicle checked.
Vehicles with sequential M gearbox
with Drivelogic:
>Have the vehicle towed with the
selector lever in position N
>Move the selector lever into position
S and pull it toward + within 2 sec-
onds. The correct gear will automati-
cally be selected and engaged
>After the engine has started, move
the selector lever into position N
again.
