Automatic transmission with Steptronic
Upshifts or downshifts will be carried
out by the ATC only at appropriate
engine speeds and road speeds. For
instance, if engine speed is too high, a
downshift will not be executed. The
gear selected will appear briefly in the
instrument cluster followed by the
current gear.
If you are driving in the manual
mode and wish to accelerate
rapidly from low road speeds (when
passing, for instance), you must shift
down manually or with the "Kickdown"
function.<
You can only change from "M/S" to
selector lever positions "P," "R," and
"N" via the "D" position.
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
> In order to prevent engine over-
speeding, the transmission shifts
automatically to the next higher gear.
shortly before the RPM cutoff point
> At low speeds, the transmission
shifts down automatically – you do
not have to act.
> In the "Kickdown" mode, the trans-
mission shifts down to the lowest
gear which is possible, depending on
the engine speed.

> According to the situation, for
instance in wintry conditions, the
vehicle can be started in 2nd or
3rd gear.

If the indicator lamp comes on
or the message "TRANS.FAIL-
SAFE PROG" appears in the
*
Check Control
, there is a fault in the
transmission system.
Bring the vehicle to a stop. Move the
transmission selector lever to "P." Set
the parking brake and turn the engine
off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission
performance has been restored. You
may continue to drive as usual. If the
indicator lamp does not go out, you can
place the selector lever in all positions.
However, the vehicle will now only drive
forward with limited gear selection.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could
move.<
