Driving
38 sion control system components, espe-
cially the catalytic converter.
Service Engine Soon indicator lamp
for Canadian models.
Malfunction in the engine electron-
ics.
You can continue to drive with
reduced engine output or engine speed.
Please have it checked by your BMW
Sports Activity Vehicle Center.
Starting the engine
When starting the engine, do not press the
accelerator pedal.
Vehicles with manual transmission:
Step on the clutch when starting the
vehicle. A lockout prevents the engine from
starting if the clutch is not depressed.<
Do not actuate the starter for too
short a time. Do not turn it for more
than approx. 20 seconds. Release the igni-
tion key immediately as soon as the engine
starts.<
If the engine fails to start on the first
attempt, for instance, if it is very hot or cold:
>Press the accelerator pedal halfway
down while engaging the starter.
During a cold start at very low tempera-
tures, as of approx. +57/Ð156, at high
altitudes over 3,300 ft/1,000 m:
>For the first attempt, run the start for
longer, approx. 10 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
Avoid frequent starting is quick suc-
cession or repeated start attempts in
which the engine does not start. Otherwise,
the fuel is not burned or inadequately
burned and there is a danger of overheat-
ing and damaging the catalytic converter.<
Manual transmission
1.Engage the handbrake
2.Gearshift lever in idle position
3.Press the clutch pedal
4.Start the engine.Before leaving the vehicle with the
engine running, place the gearshift
lever in idle position and apply the hand-
brake.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
Automatic transmission
1.Press the brake pedal
2.Place the selector lever in position P
or N
3.Start the engine.
To prevent the vehicle from rolling,
always select position P and engage
the handbrake before leaving the vehicle
with the engine running.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
Switching off the engine
Do not remove the ignition key when
the vehicle is moving, as otherwise
the steering could lock.
When leaving the vehicle, always remove
the ignition key and lock the steering.
When parking on downward inclines, apply
the handbrake.<
Manual transmission
Turn the ignition key to position 1 or 0.
Automatic transmission
Engage selector-lever position P, turn igni-
tion key to position 1 or 0.
Handbrake
The handbrake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp
The indicator lamp lights up from
ignition switch position 2 with the
handbrake set Ð an acoustic signal
also sounds when starting off.

Break-in procedures
To ensure that your vehicle provides maxi-
mum economy throughout a long service
life, we request that you observe the fol-
lowing instructions:
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 100 mph/160 km/h.
Always obey all official speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the kick-
down point.
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 one of the
differentials be replaced later in the course
of the vehicle's service life.
Tires
Due to technical factors associated with
their manufacture, tires do not achieve their
full traction potential until after an initial
break-in period. For this reason, drive with
extra care during the initial 200 miles/
300 km.
Obey your local and state maximum speed
limits.
When the vehicle is operated on wet
or slushy roads, a wedge of water
may form between the tire and the road
surface. This phenomenon is referred to as
hydroplaning and can lead to partial or
complete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake system
Approx. 300 miles/500 km must elapse
before the brake pads and rotors achieve
the optimal pad-surface and wear patterns
required for trouble-free operation and
long service life later on.
To break in the separate handbrake drums,
apply the handbrake lightly when coasting
to a standstill Ð at a traffic signal, for
instance; use caution to avoid posing a
danger to other road users.
To avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on when the
handbrake is set.
Vacuum for the brake system servo
unit on your BMW is available only
when the engine is running. When you
move the vehicle with the engine off Ð e.g.
by towing Ð substantially higher levels of
pedal force will be required to brake the
vehicle.<
Clutch
The function of the clutch is also only at its
optimized level after a distance driven of
approx. 300 miles/500 km. During this
break-in period, engage the clutch gently.
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 vari-
ous 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

Never attempt to continue driving
until the tank is completely empty, as
engine functions could be affected, and the
vehicle could sustain damage as a result.<
Fuel specifications
The engine uses lead-free gasoline only.
Required fuel:
Premium Unleaded Gasoline,
minimum 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.<

California Proposition 65
Warning
California laws require us to state the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component 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 accessories contain lead and
lead compounds. Wash your hands after
handling. Used engine oil contains chemi-
cals that have caused cancer in laboratory
animals. Always protect your skin by wash-
ing thoroughly with soap and water.<
OBD connector
The interface socket for the Onboard Diag-
nostic is located on the left of the driver's
side at the bottom of the instrument cluster
and under a cover. The cover has the let-
ters OBD on it.
The most important components for the
composition of the emissions can be
checked by a device across this interface. If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW Sports Activity
Vehicle Center at the earliest possible
opportunity.
The illuminated indicator lamp informs you
of the need for service, not that you need to
stop the vehicle. However, the systems
should be checked by your BMW Sports
Activity Vehicle Center at the next opportu-
nity.
If the indicator lamp blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW Sports Activity Vehicle Center imme-
diately. Severe engine misfiring over even a
short period of time can seriously damage
emission control system components,
especially the catalytic converter.

for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator lamp will
light up. If the fuel filler cap is then tight-
ened, the indicator lamp will usually go out
after a short period of time.<
