BMW 2004 Z4 Roadster 3.0i 사용자 매뉴얼

Driving

You accelerate from higher gears, e.g. dur-
ing passing, by downshifting manually.

In the following situations, the SMG in the
sequential mode assists you:

The transmission will only execute
upshifts and downshifts that will result
in an appropriate combination of vehi-
cle speed and engine rpm. For
instance, downshifts that would result
in excessive engine speed cannot be
executed

During a stop the gearbox is automati-
cally downshifted into first gear

Shortly before a gear-dependent mini-
mum speed is reached, the gearbox
shifts down automatically without you
taking any action.

Display in the instrument cluster

Gear indicator

R N 1 2 3 4 5 6 D1 D2 D3 D4 D5 D6

The currently engaged gear, the selected
mode, and any possible malfunctions are
displayed in the instrument cluster.

Malfunctions

Indicator lamp

If the indicator lamp comes on,
there is a malfunction in the trans-
mission system.

All of the selector lever positions can con-
tinue to be engaged; however, in the for-
ward drive positions the range of available
gears is restricted.

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

Warning tone

An acoustic signal sounds if the SMG gear-
box overheats; if possible you should either
stop or increase your pullaway speed so
that the system can cool down.

Driving Dynamic Control

The Driving Dynamic Control feature lets
you select between a standard and a sport
program.

Sport program

The engine responds more spontane-
ously to any motion of the accelerator
pedal

The vehicle is steered more directly and
traction is enhanced

Additionally with SMG and automatic
transmission:

The shifting times are reduced

The engine speed range is optimally uti-
lized in the drive mode.

Activating the Sport program

In ignition key position 2

Press the SPORT button.
The LED in the button lights up.

With automatic transmission:
The sport program of the automatic

transmission is enabled by activating the
Driving Dynamic Control system. Thus, the
selector lever does not have to be shifted
from D to M/S; refer also to page
