Automatic transmission with Steptronic*

Upshifts or downshifts will be carried

out by the ATC only at appropriate en-

gine speeds and road speeds. For in-

stance, 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 cur-

rent gear.

If you are driving in the manual

mode and wish to accelerate rap-

idly from low road speeds (when pass-

ing, for instance), you must shift down

manually or with the kickdown func-

tion.<

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 au-

tomatically 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 transmis-

sion 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.

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

engine.

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 happens, avoid extreme engine

loads and consult the nearest autho-

rized 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.<

For jump-starting, towing and tow-

starting, refer to pages 182 and 183.
