you fail to remove the ignition key after
opening the driver's door.
After removing the key, turn the
steering wheel slightly to the left or right
until the lock engages. 390de010
Steering unlocked Turning the steering wheel slightly to
the right or left often makes it easier to
turn the key from 0 to 1.
Individual electrical accessories are
ready for operation.Starting engine Depress the clutch when starting the
engine. A lockout prevents the engine
from starting with the clutch engaged.
Before starting>Engage the parking brake
>Move the gearshift lever to the neu-
tral position
>Depress the clutch pedal.
Do not allow the engine to run in
enclosed spaces. The exhaust
gases contain carbon monoxide, an
odorless and colorless, but highly toxic
gas. Breathing the exhaust gases poses
an extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<

Starting the engine Switching off the engine Starting engineDo not press the accelerator pedal
while starting the engine.
While it is important not to release
the key prematurely, you should
also avoid allowing the starter to
operate continuously for more than
20 seconds at a time. Release the igni-
tion key immediately when the engine
starts.<
Do not warm up the engine by allowing
it to run with the vehicle parked.
Instead, you should drive away immedi-
ately while taking care to avoid high
engine speeds until the engine warms
to its normal operating temperature.
If the engine does not start on the first
attempt (the engine is very hot or cold,
for instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures of roughly +57 (Ð156) or below
and at altitudes of over 3,300 ft
(1,000 m):
>Allow the starter to turn somewhat
longer (approx. 10 seconds) during
your initial starting attempt.
The engine's idle speed is automatically
regulated by the computerized engine-
management system. A brief period at
high idle is normal just after starting; the
idle speed should gradually return to
normal as the engine warms. Should
the engine fail to revert to its normal
idle speed after warming, a problem
may exist: please refer the problem to
your BMW center.
To prevent the battery from discharging,
always switch off any electrical devices
not in use, as well as the ignition when
the vehicle is not being driven.
Extended starting attempts,
characterized by excessively fre-
quent or long periods with the
starter engaged, can lead to catalyst
damage.<
When driving, standing at idle,
and parking the vehicle, take care
to avoid contact between the exhaust
system and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious per-
sonal injury and property damage.<
Turn the ignition key to position 1 or 0.
Do not remove the ignition key
while the vehicle is still moving. If
you do so, the steering will lock, making
it impossible to steer the vehicle.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Always engage the parking brake
when parking on hills and inclined sur-
faces, as even first gear or reverse may
not provide adequate resistance to
rolling.<

58n
Parking brake Manual transmission The parking brake is designed primarily
to prevent the vehicle from rolling when
it is parked. It operates on the rear
wheels.To engageThe lever engages automatically when
it is pulled up, and the "PARK BRAKE"
(in Canada "P") indicator lamp comes
on in the instrument cluster in ignition
key position 2. Refer to page 17. To releasePull up slightly on the lever, press the
button and lower the lever.390de714
If, in exceptional circumstances, it
should be 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 to apply mod-
erate pressure.
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 applied. Always
engage the parking brake when parking
on hills and inclined surfaces, as even
first gear or reverse may not provide
adequate resistance to rolling.<
You can help prevent corrosion and
maintain balanced braking by periodi-
cally pulling up the parking brake lever
gently while coasting to a stop at a
traffic light. Always check traffic condi-
tions first to avoid posing a hazard to
yourself or other road users.
When shifting gears, always depress
the clutch pedal all the way down, then
move the gearshift lever until it engages
securely in the desired gear.
You will also need to depress the clutch
when starting the engine, as an auto-
matic lockout prevents the starter from
operating when the clutch is engaged.
When the vehicle lighting is switched
on, the shift pattern is illuminated on
the gearshift lever.
When shifting gears in the 5th/
6th-gear plane, be sure to press
the gearshift lever to the right in order
to prevent inadvertent selection of a
gear in the 3rd/4th-gear plane.<39mde017

Washer/Wiper system Cruise control Cleaning headlampsWhen the headlamps are on, they are
also cleaned automatically every fifth
time you activate "Cleaning windshield"
5 or "Intensive cleaning" 6.
Do not use the washers if there is
any danger that the fluid will
freeze on the windshield, as your vision
could be obscured. You can reduce this
danger by adding a windshield washer
antifreeze. Refer to page 115. Do not
activate the washer if the reservoir is
empty, as the washer pump could be
damaged. automatically when the ignition key is in
position 2.
You can store and automatically main-
tain any desired vehicle speed above
approx. 20 mph (30 km/h).
The cruise control is available whenever
the engine is running and the system
has been activated.
To activate the system From ignition key position 2:
Press the button and the indicator lamp
on the instrument cluster (refer to
page 18) will come on. You can now
use the cruise control.
Do not use cruise control on
twisting roads, when high traffic
density prevents driving at a constant
speed, or when the road surface is slick
(snow, rain, ice) or loose (rocks or
gravel, sand). the indicator lamp in the instrument
cluster goes out.
Cruise control is also deactivated when
the ignition key is in position 0.
The speed stored in memory is deleted.

Cruise control To maintain and store speed
or to acceleratePress button (+) briefly:
The system maintains and stores the
current vehicle speed. Every time you
tap the button, the speed increases by
approx. 0.6 mph (1 km/h).
Press and hold button (+):
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the button, the system
stores and maintains the current speed.
If, on a downhill gradient, the
engine braking effect is not suffi-
cient, the controlled speed can be
exceeded. Speed can drop on uphill
grades if the engine output is insuffi-
cient.<
To deceleratePress button (Ð) briefly:
If you are already driving with active
cruise control, the speed is decreased
by approx. 0.6 mph (1 km/h) every time
you tap the button.
Press and hold button (Ð):
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the button, the
system maintains and stores the cur-
rent speed.
To interrupt the cruise controlWhen the system is activated, press the
button. The indicator lamp stays on.
You can use the cruise control again
whenever you want by calling up the
speed that was stored last.
In addition, cruise control is interrupted
automatically:
>When the brakes are applied
>When you depress the clutch pedal
>If you exceed or fall below the pro-
grammed speed for an extended
period (by depressing the acceler-
ator, for example). To recall the stored settingPress button:
The vehicle accelerates to and main-
tains the last speed stored.

Tachometer Engine oil temperature Fuel gauge The orange pre-warning zone appears
depending on the engine temperature.
As the engine temperature increases,
more and more of the sectors of this
pre-warning zone disappear.
Avoid engine speeds in the pre-warning
zone if possible.
Do not operate the engine with the
needle in the red overspeed zone of the
gauge.
To protect the engine, the engine-man-
agement system interrupts the fuel
supply when you approach this sector.39mus023
The normal operating temperature
range is between + 176 7 (+ 80 6) and
+ 248 7 (+ 120 6). Do not exceed the
maximum temperature of +302 7
(+150 6). 39mus024
When you switch on the ignition, the
indicator lamp comes on briefly to con-
firm that the system is operational.
If the indicator lamp comes on and
stays on, there are approx. 2.5 gal
(10 liters) of fuel still in the tank.
For fuel tank capacity, refer to
page 143.
If the tilt of the vehicle varies (when you
are driving in mountainous areas, for
example), the needle may fluctuate
slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<39mus025
