2004 BMW 645CI COUPE ECU

Driving
56 do not pull it too strongly. In doing so, con-
tinuously press the button of the handbrake
lever.
Strong application of the handbrake can
lead to overbraking of the rear axle and
associated 'fishtailing' of the vehicle rear
end.
The brake lamps do not light up when the
handbrake is engaged.
Vehicles with manual or SMG transmission:
When parking on inclines, engage the
handbrake, as even engaging the first or
reverse gear might not under certain cir-
cumstances secure the vehicle against
moving.
Vehicles with automatic transmission:
Engage selector-lever position P.<
To prevent corrosion and one-sided
braking action, occasionally engage
the handbrake lightly when the vehicle is
slowly coming to a standstill if the traffic
conditions are suitable.<
Manual transmission
While shifting gear in the 5th/6th gear
level, press the gearshift lever to the
right, as otherwise engine damage could
occur from inadvertently engaging a gear in
the 3rd/4th gear level.
On inclines, do not hold the vehicle with the
clutch; use the handbrake. Otherwise there
is high clutch wear.<
Reverse gear
Select only when the vehicle is completely
stationary. When pressing the gearshift
lever to the left, overcome some resis-
tance.The backup lamps automatically switch on
in ignition key position 2.
SMG Sequential manual
transmission*
The concept
The SMG Sequential manual transmission
is an automated manual transmission in
which an electro-hydraulic system handles
the clutching and gear changes.
You operate the SMG using the selector
lever in the center console and two shift
paddles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Options of two drive programs:
Normal or Sport, refer to page 59
>Protection against incorrect gearshifts
and automatic shift down at minimum
engine speed, also in the Sequential
mode
>Kickdown function in the Drive mode
>Acceleration assistant, refer to
page 60.
The SMG is operational in ignition key posi-
tion 2.
Selector-lever positions
The current selector-lever position is dis-
played on the center console.
>R: Reverse gear
>N: Neutral, idle

The currently engaged gear is displayed, in
the Drive mode preceded by a D.
Shiftlock
Press the brake pedal before shifting out
of N; the shift command will not be exe-
cuted unless the brake is applied.
R Reverse
Select only when the vehicle is completely
stationary.
Sequential mode
After every engine start, as soon as the
selector lever is pushed to the right and the
brake pedal is pressed, the Sequential
mode is activated.
The gear is changed using the shift paddles
or selector lever.
Driving off is also possible in second gear,
e.g. when the roadway is icy.
D Drive mode
In the Drive mode, all forward gears are
shifted automatically.
To switch from Sequential to Drive mode:
Briefly press the selector lever to the right
towards D.
Kickdown:
For rapid acceleration, e.g. overtaking,
press the accelerator pedal as far down as
it will go: you achieve maximum accelera-
tion.
To switch back to the Sequential mode:
briefly press the selector lever back to the
right towards D or change the current gear
using the shift paddles or selector lever.
Start off quickly on slopes. Do not
hold the vehicle on a hill by applying
the throttle, but engage the handbrake
instead. Otherwise overheating can occur
in the area of the transmission.<
Gear changes
Using selector lever
>To shift up, briefly press the selector
lever towards +
>To shift down, briefly press towards —.
Using shift paddles on steering
wheel
>To shift up, pull one of the shift paddles
>To shift down, press.
In the following situations, the SMG in the
Sequential mode assists you:
>Upshifts and downshifts are executed
only when they will result in a plausible
combination of engine and vehicle

Driving
58 speed; thus, for example, a downshift
that would cause the engine to overrev
will not be executed by the system
>When the vehicle is stationary, the
transmission automatically downshifts
into first gear
>Shortly before dropping below a gear-
dependent minimum speed, the trans-
mission downshifts automatically even
without your intervention.
Malfunction
The warning lamp lights up and a
message appears on the Control
Display. There is a malfunction in
the transmission system. Avoid high loads.
While it will remain still possible to move
the selector lever to any desired position,
the transmission will revert to operation in
its default mode with only a limited number
of forward gears.
Have the system checked as soon as pos-
sible.
Information on jump-starting and towing
begins on page 185.
Overheating
The warning lamp lights up and a
message appears on the Control
Display. In addition, an acoustic
signal sounds. Overheating in the area of
the transmission. If possible, stop or drive
off quickly so that the system can cool
down.
Automatic transmission
with Steptronic*
In addition to the fully automatic mode, you
can also shift manually with Steptronic,
refer to page 59.

the front of the selector lever knob, refer to
arrow.
Shiftlock
Press the brake pedal before shifting out
of P or N; the shift command will not be
executed unless the brake is applied.
To prevent the vehicle from creeping after
you select a driving position, maintain pres-
sure on the brake pedal until you are ready
to start.
To prevent the vehicle from rolling,
always select selector-lever posi-
tion P and engage the handbrake before
leaving the vehicle with the engine running.

function automatically.
Press the button repeatedly to run through
the following control sequence:
>Indicator lamps off: outside air flows
into the vehicle continuously
>Right indicator lamp on, AUC mode: the
system detects pollutants in the outside
air and responds by blocking the supply
of outside air when required.
Depending upon air quality require-
ments, in the automatic mode the sys-
tem alternates between its outside-air
and recirculated-air modes
>Left indicator lamp on, recirculated-air
mode: the supply of outside air into the
vehicle is continuously blocked.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing
the air volume as required.
The recirculated-air mode should not be
used over a longer period of time, as the air
quality inside the vehicle deteriorates con-
tinuously.<
Residual heat mode

Integrated universal remote
control*
The concept
The integrated universal remote control
replaces up to three different hand-held
transmitters for various items of radio-con-
trolled equipment such as door openers
and house alarm systems. The integrated
universal remote control registers and
stores signals from the original hand-held
transmitters.
The signal of an original hand-held trans-
mitter can be programmed on one of the
three memory buttons 1. Then the respec-
tive device can be actuated with the mem-
ory button 1 programmed for its use with
the ignition key in position 2. The indicator
lamp 2 flashes to confirm transmission of
the signal.
If you sell your vehicle one day, delete the
saved programs beforehand for your own
security, refer to page 95.
To prevent possible damage or injury,
before programming or using the inte-
grated universal remote control, always
inspect the immediate area to make certain
that no people, animals or objects are
within the travel range of the device. Also,
comply with the safety precautions of the
original hand-held transmitter.<
Checking compatibility
If you see this symbol on the pack-
aging or in the manual supplied with
the original hand-held transmitter, it
is safe to assume that it is compatible with
the integrated universal remote control.
If you have additional questions, please
consult your BMW Sports Activity Vehicle
Center or call 1-800-355-3515.
