Starting the engine
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.
Never leave the vehicle parked with the
engine running, as it would then pose a
potential safety hazard.<
1.Insert the remote control unit all the way
into the ignition lock
2.Depress the brake pedal
3.Maintain pressure on the brake pedal
and briefly press the start / stop button.
You can release the brake pedal as soon as
the engine starts.
Your BMW is equipped with the
convenience 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. It is then possible to start the
engine using electrical power from an
outside source, refer to page 187.
The engine starts immediately in response
to pressure on the button at speeds of
roughly 3 mph (5 km/h) and above. It is not
necessary to depress the brake pedal.<
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.
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 cold starts at high altitudes, of
roughly 3,300 ft (1000 m) and above, and in
extreme cold, at temperatures of approxi-
mately +5 7 (Ð15 6) and below.
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 engineWith 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,
maintain pressure on the start / stop button
for approx. 1 second.
If you maintain pressure on the start / stop
button for longer than two seconds while
switching off the ignition, the remote
control 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 electro-
mechanical parking brake.
The parking brake is primarily intended to
prevent the vehicle from rolling while
parked.

63
You have two separate options for
engaging the parking brake:
>Manually, by briefly pressing the button
>Automatically, through activation of the
Automatic Hold mode, refer to next
column.
An electrohydraulic mechanism then
engages the parking brakes to prevent the
rear wheels from turning whenever you
switch off the engine.
When the engine is running, parking brake
engagement is controlled by the brake
system's hydraulic circuits, which act on
the disc brakes at the front and rear
wheels. Brake pedal feel Because this function is activated using the
brake system's hydraulic circuits, the
response of the brake pedal may change
slightly. Engagement may also be accom-
panied by activation noise Ð this is normal. Manual engagement
Press the button briefly, the
word "PARK" appears briefly in
the Info Display.
The indicator lamp
appears in red in the Info
Display when the parking brake is
engaged, refer to page 14.
The indicator lamp goes out
soon after you switch off the igni-
tion.<
Manual release
With the ignition on, briefly
press the button: the indicator
lamp in the Info Display goes
out.
Provided that the detent holding the
remote control unit in the ignition lock
is engaged, you can also release the
parking brake after the engine has been
switched off. This function is intended for
use in automatic car washes, etc.<
When leaving the vehicle, always
release the remote control unit from
the detent in the ignition lock; this precau-
tion prevents children from disengaging the
parking brake, etc.
The parking brake can still be engaged at
any time when the remote control unit is
released from the detent. It is only possible
to disengage the parking brake with the
ignition on.<
If exceptional circumstances should
make it necessary to engage the
parking brake while the vehicle is in motion,
maintain pressure on the button.
The indicator lamp appears in red in the
Info Display. A gong sounds at the same
time.
The brake lamps come on.
The vehicle continues to brake automati-
cally for as long as you maintain pressure
on the button.<
When you brake the vehicle to a
virtual stop, i.e., down to a speed of
approx. 1.9 mph (3 km/h) or below, the
parking brake remains engaged.
The indicator lamp in the Info Display
appears in red. Press the button briefly to
disengage the parking brake manually.<
Automatic Hold You can activate this feature after starting
the engine; it then remains operational until
the next time the engine is switched off.
This feature provides supplementary
support during vehicle operation by auto-
matically engaging and releasing the
parking brake during stops at traffic lights,

Driving
64 in stop-and-go traffic, etc. As the vehicle
then no longer tends to "creep" when a
driving position is engaged, it is no longer
necessary to hold the vehicle by
depressing the brake pedal.
It prevents the vehicle from rolling back-
ward during uphill starts.
The parking brake also engages automati-
cally when you switch off the engine after
stopping the vehicle.
You can activate and deactivate the Auto-
matic Hold feature by selecting the
"Settings" menu in the Control Center. A
description of the Control Center is

from the Info Display panel.
You can program the programmable
function button on the steering wheel
to control the Automatic Hold function,
refer to page 53.
This will allow you to activate and deacti-
vate the Automatic Hold function quickly
and without distraction from traffic and
road conditions.< You can also deactivate Auto-
matic Hold by pressing the
button while the vehicle is
stationary. The vehicle remains
stationary, the indicator lamp
changes from green to red. Press the
button again to release the parking brake.
Driving with Automatic Hold The parking brake engages automatically
when the vehicle comes to a stop. The indi-
cator lamp in the Info Display
appears in green.
To start off again, simply depress the
accelerator pedal. The parking brake
disengages automatically, and the indi-
cator lamp goes out.
Do not drive through an automatic car
wash with the Automatic Hold on and
the engine running. The system would
engage the parking brake while the vehicle
is stationary.<Parking with Automatic Hold The parking brake engages automatically
when you stop the vehicle and switch off
the engine. The indicator lamp
changes from green to red.
Provided that the remote control unit
is engaged in the ignition lock, you
can also release the parking brake manu-
ally after switching off the engine, refer to
page 63. This option is useful in automatic
car washes, etc.

brake is engaged. The vehicle could start to
roll if you fail to observe these precautions.
Never leave an unattended vehicle with the
engine running, as such a vehicle repre-
sents a potential safety hazard.<
Automatic Hold is automatically
deactivated whenever the system
detects any tendency for the wheels to spin
in response to slippery road surfaces. Note
the status displays in the Check Control
panel. You can find more detailed informa-
tion on Check Control on page 80.< Malfunctions In the event of malfunction, the indicator
lamp in the Info Display will light up
yellow, and a status report will appear in
the Check Control panel. Please remember
to observe the supplementary information
provided in the Control Display. To disengage the parking brake
manually You can respond to any interruptions in the
supply of electrical power, for instance, if
the battery is discharged or disconnected,
by releasing the parking brake manually.
Before proceeding to release the
parking brake manually, and each
time you park the vehicle without engaging the parking brake, always ensure that the
automatic transmission's selector lever is
in position P, refer to page 66. Note the
range indicated in the Info Display.
If it is not possible to avoid parking on an
extremely steep slope, use some supple-
mentary means, such as a wheel chock, to
make certain that the vehicle will not roll,
refer to page 184. Otherwise the danger
exists that the vehicle could roll when
parked on a very steep hill.<
Should it be necessary to release the auto-
matic transmission's lockout manually, for
instance, if the battery is discharged,
always adhere to the following sequence:
1.If necessary, start by manually releasing
the parking brake
2.Then release the automatic transmis-
sion's lockout manually, refer to page 70.

can also return the parking brake to normal
operational status after it has been
released manually in response to malfunc-
tion.<
Following manual release, the actual
status of the parking brake may vary
from that displayed by the indicator lamp.<
Operation after interruptions in
power supply
The parking brake may only be used
again, if it is released manually after
an interruption in power supply, i. e. as a
result of a discharged or disconnected
battery. If this is not done, the parking
brake may fail to operate correctly. Even
with the parking brake engaged, there
would be a danger of the vehicle rolling on
steep hills.<
