Technology that monitors itself
The indicator and warning lamps identified
by the
+ symbol are subjected to an oper-
ation check each time you switch on the
ignition or start the engine. They each light
up once for different periods of time.
When a malfunction occurs in a monitored
system, the corresponding lamp will either
fail to go out when the engine is started, or
it will come on again during normal driving.
Detailed information is provided on the
specified pages.

in the Info Display.
Starting 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.
To prevent the vehicle from rolling, always
select position P on the selector lever and
engage the parking brake before leaving
the vehicle with the engine running.<
When starting the engine, do not press the
accelerator 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.
Your BMW is equipped with the conve-
nience starting feature. After pressing 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 auto-
matically.
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, below + 57/– 156, at high altitudes
over 3,281 ft/1,000 m:
>Engage the starter for approx.
10 seconds the first time
>Press the accelerator pedal halfway
down while engaging the starter.
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 con-
verter, where it can cause overheating and
damage to the unit.<
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 nec-
essary to press the brake pedal.<
Switching off engine
With the vehicle stationary, briefly press the
start/stop button. This also activates the
radio mode.
The transmission automatically shifts to
position P: interlock.
Transmission position N remains
engaged if you keep to the following
order:
1.With Comfort Access: insert the remote
control into the ignition lock
2.With the engine running, engage trans-
mission position N
3.Switch off the engine
4.Leave the remote control in the ignition
lock.
This function is useful in automatic car
washes, etc.
Position P is engaged automatically after
approx. 30 minutes or when you remove
the remote control from the ignition lock.
Remember to observe the Check Control
for status messages.<

Driving
66 Provided that the remote control is
inserted in the ignition lock, you can
also release the parking brake manually
after the engine has been switched off,
refer to page64. This function is useful in
automatic car washes, etc.
Automatic Hold is deactivated.<
When leaving the vehicle, always
release the remote control from the
detent in the ignition lock; this precaution
prevents children from disengaging the
parking brake, etc.<
For your safety
Automatic Hold is automatically deacti-
vated when
>the engine is switched off
>the system detects that the driver's seat
is not occupied while the engine is run-
ning
>the hood is opened while the engine is
running
>the luggage compartment is opened
with the transmission in position R while
the engine is running, and
>when the parking brake is used to bring
the vehicle to a stop.
The indicator lamp changes from
green to red, and the AUTO P letters in the
Info Display disappear.
Before starting off again, briefly press the
button to disengage the parking brake
manually, refer to page64, or reactivate
Automatic Hold, refer to page65.
Before leaving the vehicle with the
engine running, always move the
automatic transmission's selector lever to
position P and ensure that the parking
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 deac-
tivated whenever the system detects
any tendency for the wheels to spin in
response to slippery road surfaces. Note the status reports in the Check Control.
You can find additional information on the
Check Control on page83.<
Malfunction
If a malfunction occurs, the indicator
lamp lights up yellow in the Info Dis-
play and a status report will appear in the
Check Control. Please note any supple-
mentary information that appears on the
Control Display.
Releasing 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 page68. Note the range
indicated in the Info Display.
If the wheel must be changed on a surface
with a more severe slope, take additional
precautions to secure the vehicle from roll-
ing e.g. with a chock, refer to page204
Otherwise there is a danger that the vehicle
could start to roll if parked on a steep
slope.<
Should it also be necessary to release the
automatic 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
page70.
Jump-starting and towing, refer to
pages209 and210.
