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.

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

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.

the last display.
It will not be possible to cancel the display
if the fuel level has fallen into the reserve
range or if a Check Control status report is
currently on the screen.
Briefly press the button again to view the
last display.<
Fuel gauge
The fuel gauge mode appears automati-
cally once the fuel level falls into the
reserve range. At the same time, the words
"Fuel reserve" appear. The tank still con-
tains approx. 2.6 gallons/10 liters of fuel.
If the tilt of the vehicle varies, when you are
driving in mountainous areas, for example,
the indicator may fluctuate slightly.
It will not be possible to cancel the
computer display once the fuel level
drops into the reserve range. However, you
can still request a display of the travel
range. Computer, refer to page85.<
Fuel tank capacity: approx. 23.2 gallons/
88 liters. You can find information on refu-
eling on page186.
Refuel well before the tank is empty,
as otherwise engine functions will not
be ensured and damage can occur if you
drive down to the last drop.<
Cruising range
Displays the estimated cruising range avail-
able with the remaining fuel. The fuel level
is measured and the range is calculated
taking the driving style over the last
20 miles/30 km into account.
Always refuel as soon as possible
once your range falls to below
30 miles/50 km, as otherwise engine func-tions are not ensured and damage can
occur.<
Refueling is only registered by the com-
puter for fuel amounts above approx.
1.3 gallons/5 liters.
Remaining distance
When you enter a destination in the naviga-
tion system or manually enter a distance in
the computer prior to departure, the system
can also display the distance remaining to
your destination, refer to page132 or87.
The system automatically applies the dis-
tance to your destination using the route
recommended by the navigation system.
When you enter a destination in the
navigation system, any manual entries
will be overwritten no later than once
1,640 ft/500 meters of the calculated dis-
tance have elapsed.<
Energy Control/
current fuel consumption
Shows the current fuel consumption. This
allows you to see whether your current
driving style is conducive to fuel economy
with minimum exhaust emissions.
Average fuel consumption
The average fuel consumption is calculated
for the time during which the engine is run-
ning.
You can use the Control Display to view
your fuel consumption rate over two differ-
ent distances, refer to Computer or Trip
computer.
Average speed
Periods with the vehicle parked and the
engine off are not included in the calcula-
tions of average speed.
Reset average speed: Press button2 in the
turn indicator lever for approx. 2 seconds.

malfunction on Canadian models.
Dynamic Drive
The concept
Dynamic Drive minimizes body roll and
optimizes vehicle stability during cornering
and evasive maneuvers.
Active stabilizers at the front and rear axles
form the basis for Dynamic Drive. Suspen-
sion compliance adapts to suit driving con-
ditions, varying from performance-oriented
during cornering to smooth and comfort-
oriented when the vehicle is proceeding in
a straight line.
The system assumes operational status
each time you start the engine.
Driving with Dynamic Drive
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
Malfunction
The warning lamp lights up, accom-
panied by a status message in the
Check Control. Please take note of
the additional information on the Control
Display. A malfunction has occurred in the
system. Have the system checked as soon
as possible.
If the Dynamic Drive system switches
off in response to malfunction, please
remember to adapt your speed accord-
ingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a Check Control message stating that you
should stop appears in addition to the red
symbol, stop immediately and switch off
the engine. In this case the oil level in the
reservoir may have dropped below the min-imum, possibly owing to a leak in the
hydraulic system.
Please observe the additional instructions
provided on the Control Display.<
EDC Electronic Damping
Control*
The suspension responds to changes in
factors such as road surface, or operating
conditions such as steering and braking, by
adapting to the new conditions within frac-
tions of a second.
Two programs are available; they can be
selected in the "Settings" menu.
Comfort mode
The Comfort mode is suitable for use
throughout the vehicle's entire speed range
and regardless of load.
Sport program
You should select the Sport program for
consistently performance-oriented
response from shock absorbers and steer-
ing.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure another
tire.

Technology for comfort, convenience and safety
96 The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirements
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page189 and correct if neces-
sary
3.Initialize the system.
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natu-
ral, even pressure drop in all four tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When you are driving on snow-covered
or slippery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted.
Initializing system
Perform the initialization immediately
after correcting the inflation pressure,
changing a tire or changing a wheel or all
wheels. A drive is necessary for this pur-
pose.<
1.Start the engine, but do not drive off
2.Select "RPA" from the "Settings" menu
and confirm your selection. The initial-
ization menu appears 3.Select "SET" and confirm your selection
4.Drive off.
"FTM is being initialized" is displayed as the
status.
It takes at least 10 minutes before the Flat
Tire Monitor can detect and report a flat
tire.
When driving with snow chains, do
not initialize the system.<
Select and confirm to exit from the
menu.
Indication of a flat tire
The warning lamp lights up red,
accompanied by a status message
in the Check Control. In addition, an
acoustic signal sounds. A flat tire or a major
air loss has occurred.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW center.<
3.Replace the damaged tire, refer to
Changing wheels on page204.
