key BMW Z4 ROADSTER 3.0I 2004 E85 Owner's Guide

Driving
42 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.

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.
For jump-starting and towing, refer to the
information on page 94.
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 39.<

Cruise control*
1To maintain and store speed/
to accelerate
2To decelerate
3To recall the stored setting
4To deactivate the system
Do not use cruise control on twisting
roads, when high traffic density pre-
vents driving at a constant speed, when the
road surface is slick, e.g. from snow, rain or
ice, nor when the road surface is loose, e.g.
from rocks or sand.<
To maintain and store speed/
to accelerate
You can maintain and store any desired
speed above approx. 20 mph / 30 km/h.
Press the lever briefly in direction 1:
The system maintains and stores the cur-
rent vehicle speed. Every time you tap the
lever, the speed increases by approx.
0.6 mph / 1 km/h.
Hold the lever in position 1:
The vehicle accelerates without pressure
on the accelerator pedal. As soon as you
release the lever, the system stores and
maintains the current speed.
If, on a downhill grade, the engine
braking effect is not sufficient, the
controlled speed can be exceeded. Speed
can drop on uphill grades if the engine out-
put is insufficient.<
To decelerate
Press the lever briefly in direction 2:
When the cruise control is active, vehicle speed is reduced by approx. 0.6 mph /
1 km/h every time you tap the button.
Hold the lever in position 2:
With the cruise control active, the system
automatically reduces the throttle opening
to slow the vehicle. As soon as you release
the lever, the system stores and maintains
the current speed.
To recall the stored setting
Press the lever briefly in direction 3:
The vehicle accelerates to and maintains
the last speed stored.
To deactivate the system
Press the lever briefly in direction 4:
The cruise control is deactivated immedi-
ately.
In addition, the system is automatically
deactivated in response to the following
conditions:
>When you apply the brakes
>When you depress the clutch or move
the automatic selector lever from D to N
>If you exceed or fall below the preset
speed for an extended period, for
example by depressing the accelerator.
You can recall the speed last stored.
Cruise control is also deactivated when the
ignition key is turned to position 0.
The stored speed is cleared in this case.

Parking lamps/Low beams
Parking lamps
The front, rear and side vehicle
lighting is switched on. You can use
the parking lamps to signal the
position of the vehicle when it is parked.
For information on lighting on one side of
the vehicle for parking, which is available
as an additional feature, refer to page 47.
Low beams
When you switch off the ignition
with the low beam headlamps on,
only the parking lamps will remain
on.
Defective bulbs
The indicator lamp lights up:
At least one bulb of the vehicle's
exterior lighting has failed.
For replacing bulbs refer to page 88.
Follow me home lamps
When you activate the headlamp flasher
after parking the vehicle and switching off
the lights, the low beams will come on for a
brief period.
You can also have this function acti-
vated/deactivated if you wish.<
LIGHTS ON warning
Whenever you open the driver's door after
having turned the ignition key to position 0,
you will hear an acoustic signal for a few seconds to remind you that the lamps have
not been switched off
.
Daytime driving lamps*
If you desire, the light switch can be left in
the second position:
When the ignition is switched off, the exter-
nal lighting is also switched off.
You can have the activation settings
for the daytime driving lamps pro-
grammed on your vehicle.<
Automatic headlamp control*
When the switch is set to this posi-
tion, the system automatically acti-
vates and cancels the low beams in
response to changes in ambient light, for
example in tunnels, at dusk, and when it is
raining or snowing.
The vehicle's external lights remain
on constantly when you switch on the
front fog lamps after the headlamps have
come on automatically.<
Automatic headlamp control cannot
serve as a substitute for the driver's
judgement in determining when the vehicle
lights should be switched on. For example,
the sensors are not able to detect fog. To
avoid safety risks, you should respond to
these kinds of low-visibility situations by
switching the headlamps on manually.<
You can have the sensitivity of your
vehicle's automatic headlamp control
adjusted.<
