Driving

. We recommend this program for

performance-oriented driving.

When you press the S/M/D button a sec-
ond time the transmission switches to its
manual mode; press again to return to the
automatic program.

You can also return to the standard auto-
matic program by reselecting D.

In the manual mode the transmission
upshifts when you briefly press the buttons
on the rear of the steering wheel. You
downshift by briefly pressing the buttons
on the front of the steering wheel. The Info
Display shows the manual ranges M1
through M6.

Upshifts and downshifts are executed only
when they will result in a plausible combi-
nation of engine and vehicle speed; thus,
for example, a downshift that would cause
the engine to overrev will not be executed
by the system. The selected gear appears
briefly in the Info Display, followed by the
current gear.

To obtain maximum acceleration, for
passing maneuvers, etc., during

operation in the manual mode, use the
kickdown or downshift manually.

Malfunctions

A status report will appear in the Check
Control to alert you to any malfunctions in
the transmission-control system. Please
note any supplementary information that
appears on the Control Display. The direc-
tional arrows also start to flash in the Info
Display.

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.

Some types of malfunction will make it
impossible to engage all gears.

The engine may respond with reduced out-
put when accelerating from a standing
start.

If this happens, avoid extreme engine loads
and consult the nearest BMW center.

If no status messages appear in the
Info Display you should accelerate

carefully to confirm that you are driving in
the desired direction.
Never work in the engine compartment
with any of the forward or reverse gears
engaged, as the vehicle could start to
move. Engaging the parking brake, refer to
page

Manual release of transmission
lockout

You can respond to any interruptions in the
supply of electrical power, for instance, if
the battery is discharged or disconnected,
by releasing the transmission lockout man-
ually.

To prevent the drive wheels from
locking up and sliding, the transmis-

sion lockout must always be released man-
ually before the vehicle is towed.

Press the brake pedal before releas-
ing the transmission lockout manu-

ally. If the brakes are not applied, the vehi-
cle could start to roll if parked on a steep
slope.
The transmission lockout should only be
released for towing. Remember to engage
the transmission lockout when you repark
the vehicle after moving it.
Should it also be necessary to release
the parking brake manually, owing to a dis-
charged battery, etc., always adhere to the
following sequence:

Start by manually releasing the parking
brake, refer to page

Then proceed to manually release the
transmission lockout.

Jump-starting and towing, refer to
