2008 BMW Z4 3.0SI ROADSTER start stop button

Opening and closing
28 out. Every time you close the convertible top,
keep the button pressed until the windows are
completely closed; pinch protection will be sus-
pended during this operation.<
When the convertible top has been stored
in the convertible top compartment for an
extended period of time, e.g. in the winter
months because the hardtop was being used,
you may have to support the convertible top by
hand when closing it for the first time. If the con-
vertible top stops right before the closing phase
is completed, press against the front part of the
convertible top frame from the outside to help
the closing process along. Keep pressing the
button while doing so until the top starts mov-
ing on its own again.<
Indicator lamps
>The red LED in the button is lit while the
convertible top is in motion. It goes out as
soon as the opening or closing operation
has been completed.
>If the red LED in the button flashes after the
button has been released, then the opening
or closing operation has not yet been com-
pleted.
The movement can be continued in the
desired direction by pressing this button.
>If the yellow LED in the button comes on
when the button is pressed, the convertible
top compartment panel in the cargo bay has
been folded up. The convertible top cannot
be moved.
Interruption
The automatic sequence will be interrupted
immediately if you release the button that oper-
ates the top. The sequence can be continued in

Automatic transmission
1.Depress the brake.
2.Start the engine.
Special starting conditions
In the following situations, press the accelerator
pedal halfway down when starting the engine:
>If the engine does not start on the first
attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. +57/–156, at high
altitudes above approx. 3,300 ft/1,000 m.
Avoid frequent starting attempts in quick
succession or repeated starting attempts
during which the engine does not start. Other-
wise, the fuel is not burned or inadequately
burned; there is a danger of overheating and
damaging the catalytic converter.<
Switching off the engine
Do not remove the key while the vehicle is
still moving. Otherwise, the steering lock
would engage when the steering wheel is
turned.
When you leave the vehicle, always remove the
key and engage the steering lock.
Apply the parking brake when parking on steep
gradients, otherwise the vehicle could start to
roll.<
You can have an acoustic signal set as a
reminder that the key is still in the ignition
switch after the driver's door has been
opened.<
Manual transmission
1.Turn the key to position 1 or 0.
2.Engage first gear or reverse gear.
3.Apply the parking brake.
Automatic transmission
1.With the car at a standstill, move the selec-
tor lever to position P.
2.Turn the key to position 1 or 0.
Parking brake
The parking brake is designed primarily to pre-
vent the vehicle from rolling when parked. It
operates against the rear wheels.
Indicator lamp
The indicator lamp is lit, and when you
drive off a signal sounds in addition.
The parking brake is still applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
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. In doing so, continuously
press the button of the parking brake lever. Oth-
erwise, too violent an application of the parking
brake can overbrake the rear axle and cause the
rear of the car to swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally apply the parking
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<

Add engine oil at the earliest opportunity, e.g.
when you stop to refuel.
The warning lamp lights up in yellow
within 30 seconds after the engine is
started: the oil level sensor is defective.
It is not possible to issue a current or accurate
measurement. Have the system checked as
soon as possible.
Checking the oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, i.e. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
You can have the oil level reading displayed in
the instrument cluster.
Press button1. The oil level is checked and dis-
played for approx. 15 seconds.
To exit the display sooner, press button 1 again.
Possible displays
1Oil level OK
2Oil level is being checked.
This can take about 3 minutes if the car is at
a standstill on a level surface, or about
5 minutes while the car is on the move.
3Oil level down to minimum:
Add 1 US quart/1 liter of engine oil as soon
as possible, refer also to Adding engine oil.
4Oil level is too high.
Have the vehicle checked immedi-
ately, as excessive oil can damage the
engine.<
5The oil level sensor is defective:
it is not possible to issue a current or accu-
rate measurement.
Do not add engine oil. You can continue
your journey. Have the system checked as
soon as possible.
