Odometer, outside
temperature display, clock
When the ignition is off you can briefly acti-
vate the time, outside temperature and
odometer displays by pressing the knob 3
at the lower left of the instrument cluster.
Outside temperature display, clock,

on the Control Display, refer to Measure-
ment units on page 72.
To call up the date:
Briefly press the CHECK button on the turn
indicator lever, refer to page 69.

Ice warning
A signal sounds when the outside temper-
ature falls to roughly +37.57/+36; this is
accompanied by a message.
Please bear in mind that the ice warn-
ing does nothing to alter the fact that
black ice may be present on roads at tem-
peratures higher than +37.57/+36, e.g.
on bridges and shaded roads.<
Odometer and trip odometer 2
To reset the trip odometer to zero:
Press button 3 in the instrument cluster.
Tachometer
The white-striped advance warning field,
arrow 1, changes depending on the engine
temperature. The segments disappear in
sequence as the engine warms to its nor-
mal operating temperature.
Avoid allowing the engine speed to rise as
far as the advance warning field whenever
possible.
Engine speeds in the red warning field,
arrow 2, must be avoided.
In this range, the fuel supply is interrupted
to protect the engine.

Engine oil thermometer
The engine oil temperature is between
approx. 1607/706 and approx. 3407/
1706 during normal operation.
If the engine oil temperature is too high, a
message appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal-
lons/70 liters, including the reserve capac-
ity of approx. 2.1 gallons/8 liters. You can
find information on refueling on page 162.
If the tilt of the vehicle varies for a longer
period, when you are driving in mountain-
ous areas, for example, the indicator may
fluctuate slightly.
After the reserve quantity has been
reached, a message appears for a short
time on the Control Display; the remaining
range is shown in the computer. Below a
range of approx. 30 miles/50 km, the mes-
sage remains on the Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, as otherwise engine functions are
not ensured and damage can occur.<
Service requirement display
In instrument cluster
The remaining distance to be driven, the
date for the next maintenance as well as
the date entered for the state emission or
vehicle inspection are displayed briefly as
of ignition key position 2, if the date is
imminent.
Your BMW Service Advisor will deter-
mine your vehicle's current service
requirements by reading out the data
stored in the vehicle key.<
On Control Display
You can view additional information on ser-
vice and maintenance procedures on the
Control Display.

2.Select "Service" and press the control-
ler
3.Select "Service requirements" and
press the controller
4.Select "Status" and press the control-
ler.

Mode selection
As of ignition key position 1, you can use
the BC button in the turn signal lever to call
up computer information in the instrument
cluster.
A new function appears each time you
briefly press the BC button.
Displays in instrument cluster
The display sequence:
>Cruising range
>Average speed
>Average fuel consumption.
Cruising range
Displays the estimated cruising range
available with the remaining fuel. The sys-
tem calculates the cruising range based on
operating conditions over the last 20 miles/
30 km and the amount of fuel remaining in
the tank.
Always refuel as soon as possible
once your cruising range falls to
below 30 miles/50 km, as otherwise engine
functions are not ensured and damage can
occur.<
Average fuel consumption
The average fuel consumption is calculated
for the time during which the engine is run-
ning.
You can use the Control Display to view
your fuel consumption rate over two differ-
ent distances, refer to Computer or Trip
computer.
To reset the average fuel consumption:
press the BC button in the turn signal lever
for approx. 2 seconds.
Average speed
Periods with the vehicle parked and the
engine off are not included in the calcula-
tions of average speed.
To reset the average speed: press the
BC button in the turn signal lever for
approx. 2 seconds.

DSC Dynamic Stability Control
DSC optimizes vehicle stability during
acceleration and when starting from a full
stop, as well as optimizing traction. The
system recognizes any tendency for the
vehicle to assume an unstable attitude
such as oversteer or understeer; it then
counteracts this tendency with a combina-
tion of graduated reductions in engine
torque and selective braking intervention at
individual wheels. DSC provides optimal
stability within the limits defined by the
laws of physics.
The DSC is operational every time you start
the engine. DSC includes the functionality
of the DTC Dynamic Traction Control and
DBC Dynamic Brake Control, see below.
Indicator lamp
The indicator lamp goes out soon
after you start the engine.
The indicator lamp flashes:
DSC controls the drive and braking forces.
The indicator lamp stays lit:
DSC has been switched off via the button.
DTC Dynamic Traction Control
In special driving states, e.g. in deep snow,
DTC ensures maximum forward momen-
tum. The gain in forward momentum also
involves a reduction in driving stability.
DTC is active up to approx. 45 mph/
70 km/h, whereas DSC is only effective to
a limited degree.
You may find it useful to briefly activate
DTC under the following special circum-
stances:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>When ascending snow-covered hills,
and when driving in deep or on hard-
packed snow
>When driving with snow chains.
Activating DTC
>Press the DSC button briefly; the DTC
indicator lamp in the instrument cluster
lights up continuously.
Deactivating DTC again
Press the DSC button briefly again; the
DTC indicator lamp in the instrument clus-
ter goes out.
Switching off DSC
Press the DSC button until the DSC indica-
tor light in the instrument cluster lights up
continuously, however not longer than
approx. 10 seconds. DSC and DTC are
deactivated. In addition, the stability pro-
moting intervention of the active steering is
deactivated, refer to page 80.
A message appears on the Control Display.
Please note any supplementary information
that appears there.
To maintain optimal stability, drive
with the system on whenever possi-
ble.<
Reactivating DSC
Press the DSC button briefly; the indicator
lamp in the instrument cluster goes out.

Technology for comfort, convenience and safety

Airbag system operational
The airbag warning lamp in the instrument
cluster indicates the operational readiness
of the entire airbag system and the safety
belt tensioners as of ignition key position 1.
The warning lamp goes out after a few sec-
onds.
Airbag system malfunction
Have the airbag system checked
immediately if a malfunction occurs,
as otherwise there is a danger of the sys-
tem not responding in the expected man-
ner to an impact occurring within its normal
response range.<
There is a malfunction in the airbag
system when:
>The warning lamp does not light up as
of ignition key position 1
>The warning lamp remains on continu-
ously
>The warning lamp lights up while the
vehicle is being driven.
Convertible:
Rollover protection system
The rollover protection system is automati-
cally activated in the event of an accident
or a critical driving situation, extreme incli-
nation on the longitudinal or transverse
axis, or loss of ground contact. The rollover
bars located behind the rear head
restraints move out within fractions of a
second.As a supplement to the rollover bar inte-
grated in the windshield frame, the rollover
protection system ensures that all vehicle
occupants have the necessary headroom.
Always keep the path of movement of
the rollover protection system clear.
In less severe accidents, you are protected
by the fastened safety belt and, depending
on the severity of the accident, the belt ten-
sioner and the multistage airbag restraint
system.<
Lowering
If the protection function was not required
after automatic activation, the rollover pro-
tection system can be lowered again.
No tools are necessary for this purpose.
1.Press the release backwards and hold
in that position
2.Press the rollover bar halfway down
from above
3.Let go of the release
4.Press the rollover bar down until it
snaps into place
5.Use the same procedure for the second
rollover bar.
Have the rollover protection system
checked after unexpected triggering.
