Starting the engine
Do not run the engine in closed
rooms, as otherwise the inhaling of
toxic exhaust gases can cause uncon-
sciousness and death. The exhaust gases
contain carbon monoxide, an odorless and
colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
1.Insert the remote control unit all the way
into the ignition lock
2.Depress the brake pedal
3.Briefly press the start/stop button.
Your BMW is equipped with the con-
venience starting feature. After
depressing the brake pedal, all you need to
do is briefly press the start/stop button.
The system responds by automatically
engaging the starter and allowing it to run
until the engine starts, after which it then
disengages automatically.
The automatic starting mode will not
operate or will be canceled if the battery
voltage is low. The engine can be started
by jump-starting, refer to page 202.<
Do not allow the engine to warm up by
leaving it running while the vehicle remains
stationary. Instead, begin to drive immedi-
ately at a moderate engine speed.
If you have accidentally switched off
the engine while driving, it can be
restarted from a speed of approx. 3 mph/
5 km/h by pressing the button. It is not
necessary to depress the brake pedal.< Under the following conditions you should
press the accelerator pedal halfway down
when starting:
>If the engine fails to start on the first
attempt, for instance, if it is very hot or
cold
>During a cold start at high altitudes,
from approx. 3,281 ft/1,000 m, at very
low temperatures, from approx. + 5 7/
Ð 15 6.
Refrain from starting the vehicle
repeatedly at brief intervals, and
avoid an excessive number of starting
attempts if the vehicle fails to start;
repeated activation of the starter over an
extended period would allow unburned or
only partially combusted fuel to enter the
catalytic converter, where it can cause
overheating and damage to the unit.<
Switching off the engine
With the vehicle stationary, briefly press the
start/stop button. This also activates the
radio mode.
Should exceptional circumstances
render it necessary for you to switch
off the engine while the vehicle is moving,
press the start/stop button for approxi-
mately 1 second.
If you maintain pressure on the start/stop
button for longer than two seconds while
switching off the ignition, the remote con-
trol unit will be ejected.<
Always remove the remote control
unit from the ignition lock before
leaving the vehicle.<
Parking brake
The concept
Your BMW is equipped with an electrome-
chanical parking brake.
The parking brake is primarily intended to
prevent the vehicle from rolling while
parked.

Break-in procedures
To ensure that your vehicle continues to
furnish optimal economy of operation
throughout an extended service life, we
request that you devote careful attention to
the following section.
Engine and differential
Up to 1,200 miles (2,000 km):
During this initial period you should attempt
to avoid constant, steady-state operation
and vary both vehicle and engine speeds
as often as possible. Until the break-in
period has been completed you should
also refrain from exceeding the following:
>4,500 rpm or 105 mph (170 km/h)
Always obey all official speed limits.
Avoid full-throttle operation and use of the
transmission's kickdown mode during
these initial miles.
Once you have driven 1,200 miles
(2,000 km), the engine and vehicle speeds
can be gradually increased.
You should also comply with these break-in
procedures should the engine or differen-
tial need to be replaced at a later point.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. Therefore, drive reservedly
during the first 200 miles (300 km).
Brake system
Brakes require an initial break-in period of
approx. 300 miles (500 km) to achieve
optimal contact and wear patterns
between brake pads and rotors.
General driving notes
High temperatures
Extreme temperatures occur at the
catalytic converter on this and every
catalyst-equipped vehicle. Do not remove
the heat shields installed adjacent to
various sections of the exhaust system,
and never apply undercoating to them.
When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any
highly flammable materials such as hay,
leaves, grass, etc. Such contact could lead
to a fire, and with it the risk of serious pro-
perty damage as well as personal injury.<
Parking the vehicle
Condensation forms in the air conditioner
system during operation, and then exits
under the vehicle. Traces of condensed
water under the vehicle are thus normal.
Before driving into the car wash
1.Fold in the door mirrors, refer to
page 52, as otherwise they could be
damaged due to the width of the vehicle
2.Leave the remote control in the ignition
lock, as otherwise the P position of the
automatic transmission will automati-
cally be selected when the remote con-
trol is removed. Also refer to page 68
3.Release the parking brake, especially
when you have activated Automatic
Hold. Refer to pages 63 and 64.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a
wedge of water can form between tires and
road surface. This phenomenon is referred
to as hydroplaning, and is characterized by
a partial or complete loss of contact bet-
ween tires and road surface, ultimately

Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti-Knock Index.
Do not use leaded fuels. The use of
leaded fuels will cause permanent
damage to the system's oxygen sensor and
the catalytic converter.<

Rules and regulations
California Proposition 65
Warning
California laws require us to state the fol-
lowing warning:
Engine exhaust, some of its constitu-
ents, and certain vehicle components
contain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of compo-
nent wear contain or emit chemicals known
to the State of California to cause cancer
and birth defects or other reproductive
harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling.
Used engine oil contains chemicals that
have caused cancer in laboratory animals.
Always protect your skin by washing tho-
roughly with soap and water.<
OBD connector
The Onboard Diagnostic Ð OBD Ð 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 emission
control system for the vehicle's lifetime.
The system monitors emission-related components and systems for deterioration
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.
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 emis-
sions control components, especially the
catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system 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.<
