BMW BMW AG X5 4.4i Automobile User Manual


 
68n
Automatic transmission with Steptronic
engine speed is too high, for instance,
the 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 rap-
idly – to pass another vehicle, for exam-
ple – shift down manually or with the
kickdown function.<
You can only change from M/S to se-
lector 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
possible gear based on the engine
speed.
> Depending on the situation – when
driving in adverse winter conditions,
for example – you may also start out
in 2nd or 3rd gear.
Electronic transmission control
module
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 en-
gine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual. If the indica-
tor lamp does not go out, you can place
the selector lever in all positions. How-
ever, the vehicle will now only drive for-
ward with limited gear selection.
If this should occur, avoid extreme en-
gine loads and consult the nearest au-
thorized 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.<

ing and towing begins on page 170.
