automatic transmission BMW 550I 2006 User Guide

Driving
66 fares. Especially on longer trips, the system can
reduce fatigue and tension, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
In addition to holding a steady cruising speed,
if you encounter slower vehicles ahead, active
cruise control will, within the scope of given
possibilities, adjust your vehicle's speed auto-
matically so that you can flow with the traffic
without having to make constant adjustments.
If, for example, while cruising at the selected
speed, you begin to approach a slower vehicle
ahead of you in the same lane, the system will
reduce your vehicle's speed to the same as that
of the vehicle ahead to maintain your selected
distance setting between your vehicle and the
vehicle ahead. You can vary the distance, which
is additionally speed-dependent. Based on
your selected distance setting, the system
automatically decreases the throttle setting and
lightly applies the brakes if necessary. The vehi-
cle brake lamps will automatically illuminate to
signal a following driver to take action. In addi-
tion, it may be necessary for the vehicle or the
driver to downshift, depending on the kind of
transmission your vehicle is equipped with, to
maintain the distance setting selected. If the
vehicle ahead speeds up or when the lane
ahead becomes clear, your vehicle will acceler-
ate to the speed you have selected by increas-
ing the throttle setting and shifting gears auto-
matically or by the driver as needed. Your
selected speed will be held when driving down-
hill, too.
Active cruise control is not and must not
be used as a collision avoidance/warning
system.<
Since this active cruise control system is
a new technology and operates differ-
ently from conventional cruise control systems
which you may be accustomed to, you are
strongly urged to read all of the pages relating
to this system before use. Pay special attention
to the information contained in the Things to
know about active cruise control section begin-
ning on page69.<
Navigation system Professional*
If a navigation DVD is in the drive, refer to
page124, the system adjusts the accelerating
and braking behavior of the vehicle to the road
you are driving on.
When the vehicle position is unknown, e.g.
when you leave the map area, this influence of
the navigation system is not available.
Manual transmission
You can shift with the cruise control activated.
Shifting information is provided or the system
deactivates itself if you drive at very high or very
low engine speeds for a longer period.
SMG
In the Sequential mode, shifting information is
provided or the system deactivates itself if you
drive at very high engine speeds for a longer
period.
In the Drive mode the SMG acts similarly to an
automatic transmission in the D position.

tance, refer to page68
5Select distance to vehicle driving ahead,

Maintaining current speed
Briefly press lever, arrow1, or briefly pull,
arrow2, at a driving speed of more than approx.
20 mph or 30 km/h.

Driving
70 to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
a warning to you. Also, be aware that every
decrease in the distance setting allows your
vehicle to come closer to a vehicle in front of
you and requires a heightened amount of alert-
ness.<
If while your vehicle is actively following a vehi-
cle in front of you and the vehicle ahead speeds
up or the lane ahead becomes clear, then your
vehicle will accelerate to the speed you have
selected. Be aware that changing to a clear,
unobstructed lane will also result in your vehicle
accelerating.
Be certain to deactivate the system when
you pull into an exit lane for a highway off-
ramp.<
Also, vehicles traveling in a staggered manner
on a highway may cause a delay in the system's
reaction to a vehicle in front of you or may cause
the system to react to a vehicle actually in the
lane next to you. Always be ready to take action
or apply the brakes if necessary.
Active cruise control can only decelerate the
vehicle to approx. 20 mph/30 km/h. If the sys-
tem reduces vehicle speed below 20 mph/
30 km/h or if DSC/ABS is engaged while driving,
the system will automatically deactivate.
Remember, the system cannot stop your
vehicle. In addition, the system is deacti-
vated whenever the driver applies the vehicle
brakes, shifts the transmission to neutral/N, or
deactivates DSC. After any deactivation, the
system will no longer automatically activate the
vehicle brakes, which means the driver must
intervene and resume manual braking. You
should then reactivate the system only when
you are fully aware of the prior speed and dis-
tance settings. reduce the stored desired speed; however, the
driver must constantly monitor traffic and inter-
vene if necessary.
When you switch off the engine or ignition,
active cruise control is fully switched off, too,
and any settings you have selected are can-
celed.
Swerving vehicles
When a vehicle moves from an adjacent lane
into your lane, active cruise control will not rec-
ognize this vehicle until it is fully in your lane
ahead of your vehicle.
Behavior in curves
Because of the limited range of the system, it is
possible that in curves or on the peaks and val-
leys of hilly roads, a vehicle ahead may be rec-
ognized late, or not at all. Therefore, it is up to
the driver to select a speed that is prudent in
view of the curves and terrain of the roadway.

HDC Hill Descent Control on 525xi,
530xi
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately twice walking speed without
active intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately double
walking speed, approx. 7 mph/12 km/h, and
then maintains this speed at a constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.
Activating HDC
You can activate HDC:
>with the programmable buttons on the
steering wheel, refer to page51
>or via iDrive
iDrive, for principle details, refer to page16.
1.Open the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.Select "HDC" and press the controller.5.Select "HDC on" and press the controller.
The HDC display in the instrument cluster
appears.
If the vehicle is automatically braked, a message
appears on the Control Display for approx.
20 seconds.
Deactivating HDC
When you use the programmable buttons on
the steering wheel or via iDrive, the HDC display
goes out.
Over approx. 37 mph/60 km/h HDC is immedi-
ately deactivated, and after approx. 10 seconds
when the ignition is switched off.
Using HDC
Manual transmission:
Use HDC in low gears and reverse gear.
Automatic transmission:
You can use HDC in every drive position.
Displays in instrument cluster

Malfunction
If the HDC display goes out in the HDC mode or
does not appear:
HDC is temporarily not available, as the brake
temperature is too high.

Things to remember when driving

Things to remember when driving
Break-in period
Moving parts need breaking-in time to adjust to
each other. To ensure that your vehicle contin-
ues to provide optimized economy of operation
throughout an extended service life, we request
that you devote careful attention to the follow-
ing section.
Engine and differential
Always obey all official speed limits.
Up to 1,200 miles/2,000 km
Drive at changing engine and driving speeds,
however do not exceed 4,500 rpm or 100 mph/
160 km/h.
Avoid full-throttle operation and use of the
transmission's kick-down mode during these
initial miles.
From 1,200 miles/2,000 km
The engine and vehicle speed can gradually be
increased.
SMG Sequential Manual Gearbox
Do not use the acceleration assistant during the
break-in period, refer to page61.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. Therefore, drive reservedly during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive in a reserved manner during
this break-in period.
Clutch
The function of the clutch is only at its opti-
mized level after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following part replacement
Observe the break-in instructions again if com-
ponents mentioned above must be replaced
after subsequent driving operation.
General driving notes
Closing luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is com-
pletely closed. Otherwise, exhaust fumes could
enter the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
luggage compartment lid/tailgate open:
1.Close all windows and the glass sunroof or
panorama glass sunroof.
2.Increase the air volume of the automatic
climate control to a high level, refer to
page100.
Hot exhaust system
As in all vehicles, extremely high temper-
atures are generated on exhaust system.
Do not remove the heat shields installed adja-
cent to it, and never apply undercoating to
them. When driving, standing at idle and while
parking take care to avoid possible contact
between the hot exhaust system and any highly
flammable materials such as hay, leaves, grass,
etc. Such contact could lead to a fire, and with it
the risk of serious property damage as well as
personal injury.<

Mobile communications devices in
vehicle
BMW discourages the use of mobile
communications devices, e. g. mobile
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors,
automatic dimming feature*
This feature is controlled by two photocells in
the inside rearview mirror. One is integrated into
the glass of the mirror, while the other is located
at an offset position on the rear of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach stickers of any kind to the windshield
in front of the mirror, either.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page193.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential Manual Gearbox
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Starting assistant
The starting assistant enables you to start off
conveniently on slopes. The parking brake is
not required for this purpose.
1.Hold the vehicle with the footbrake.
2.Release the footbrake and immediately
drive off quickly.
The starting assistant holds the vehicle
for approx. 2 seconds after releasing the
footbrake. Depending on the load, the vehicle
may also roll back slightly during this time.
After releasing the footbrake, immediately start
quickly, otherwise the starting assistant no
longer holds the vehicle after approx. 2 seconds
and it begins to roll back.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.

Things to remember when driving
118 Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
The braking effect of the engine can be further
increased by downshifting in the manual mode
of the automatic transmission, if necessary into
first gear, refer to page62. This prevents over-
loading of the brakes.
Do not drive with the clutch depressed, in
idle or with the engine switched off, other-
wise there will be no engine braking action or
support of the braking force and steering.
Never allow floor mats, carpets or any other
objects to protrude into the area of movement
of the pedals and impair their operation.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle. Traces of condensed water under the
vehicle are therefore normal.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
With comfort access and automatic
transmission
Insert the remote control into the ignition lock.
The engine can be switched off in the selector
lever position N. Also refer to page39.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, this could

Telephoning
The concept
Your BMW is equipped with a full mobile phone
preparation package. After logging on a suitable
mobile phone on the vehicle once, you can
operate the mobile phone via iDrive, with the
buttons on the steering wheel and by voice.
A mobile phone that has been logged on once is
automatically detected again with the engine
running or the ignition switched on as soon as
it is in the vehicle interior. The logon data of up
to four mobile phones can be stored simulta-
neously. If several mobile phones are detected
simultaneously, the respective last mobile
phone logged on can be operated via the vehi-
cle.
Using a phone in your vehicle
Using the snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW cen-
ter which mobile phones snap-in adapters are
offered for.
BMW discourages the use of mobile
phones or other mobile communications
devices inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate owner's manual for a detailed
description of safety precautions and informa-
tion, we request that you direct your particular
attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do
not observe this precaution, your being dis-
tracted can endanger vehicle occupants and
other road users.<
Suitable mobile phones
Ask your BMW center which mobile phones
with a Bluetooth interface are supported by the
mobile phone preparation package or which
mobile phones snap-in adapters are available
for. These mobile phones support the functions
described in this Owner's Manual with a certain
software version. Malfunctions can occur with
other mobile phones.
Care instructions
You can find what you need to know about car-
ing for your mobile phone in the separate Caring
for your vehicle brochure and in the mobile
phone owner's manual.
Operating options
You can operate the mobile phone* using:
>The steering wheel, refer to page11
>iDrive, refer to page16

TeleService , BMW Assist
TeleService
TeleService supports you when communicat-
ing with a BMW center. The built-in car phone
can be used to transmit data regarding the ser-
vice status of your vehicle or regarding legally
mandated inspections directly to your BMW
center. This is the same data that is also stored
for CBS Condition Based Service in the remove
control. Your BMW center can then contact
you, and you can make an appointment that
suits you while you are still on the road. Your
advantage here is that your BMW center can
prepare in advance for the required mainte-
nance work. The TeleService functions are
country-specific: the data regarding the service
status of your vehicle or regarding legally man-
dated inspections is transmitted on a country-
specific basis either automatically before they
fall due or during your calls to the BMW center.
Your BMW center will be glad to provide more
detailed information.
BMW Assist
BMW Assist provides you with other services in
addition to TeleService. For example, the posi-
tion data of your vehicle can be transferred to
the BMW Assist response center if an emer-
gency call
* has been initiated.
Many functions of BMW Assist depend on the
individually agreed contract. Data transmission,
e. g. of the CBS Condition Based Service, dif-
fers from country to country.
The contract of participation with BMW Assist
and the activation must be completed before
you can use BMW Assist.
When the contract expires, the car phone can
be deactivated by a BMW center without having
to visit a BMW center. Following deactivation of
the car phone, no emergency calls can be
made. The car phone can be reactivated after
signing a new contract with a BMW center.You can also use the services of BMW Assist via
the Internet. The range of services is continually
being expanded.
Requirements
You can use TeleService or BMW Assist when
the following requirements are met:
>The installed car phone is logged on to a
cellular telephone network. This network
must be capable of transmitting the ser-
vices.
>To transmit position data, the vehicle must
be able to determine the current position.
This can be displayed on the Control Dis-
play.
>For TeleService or BMW Assist to be acti-
vated and updated, the GPS signal must be
available.
>For BMW Assist: you have applied to your
BMW center or BMW Customer Support for
BMW Assist.
Enabling TeleService or BMW Assist
For you to be able to use the services of
TeleService or BMW Assist, these must be
