Sequential manual gearbox SMG* BMW 325i, 330i
The principle
The sequential manual gearbox SMG is
an automated manual transmission in
which an electro-hydraulic system actu-
ates the clutch and shifts gear.
You operate the SMG by means of a
selector lever in the centre console and
two shift paddles on the steering wheel.
It offers you the following functions:
>
Sequential, automated gearshift
mode cruise mode
>
Choice of two driving programs (nor-
mal or sport) in sequential mode
>
Acceleration assistant (launch con-
trol)
>
Automatic double declutching
>
Dependability of positive gearshifts
>
Automatic upshifts at maximum
engine rpm
>
Automatic downshifts at minimum
engine rpm
>
Kick-down function.
Selector lever positions
R: Reverse
N: Neutral
Forward position with touch-shift func-
tions:

The SMG is operational from ignition
key position 2 on.
When the car is at a standstill, a safety
function requires you to depress the
brake pedal if you want to move the
selector lever to a drive position within
approximately 2 seconds of selecting
neutral shiftlock function.
R Reverse
Engage this gear only when the car is
standing still.
N Neutral
Always move the selector lever to this
position before starting the engine.
Sequential mode
When you start the engine, the sequen-
tial mode is always activated as soon as
you depress the brake pedal and move
the selector lever to the forward posi-
tion.
C Cruise mode
All forward gears are shifted automati-
cally in cruise mode.
To change from sequential mode to
cruise mode: lightly press the selector
lever to the right toward "C".
Sharply press the accelerator all the
way down for rapid acceleration (kick-
down) when you want to overtake,
for example.
Kick-down
You can achieve maximum acceleration
and top speed using kick-down.
