Rollover protection system2. Pull up on the lever (arrow) toward
the front of the vehicle and keep it in
this position
3. Keep pressing down on the protec-
tive bar 1 from on top until you hear it
click into place
4. Put the cover panel back in place
and press down firmly
5. Press the rear part of the head
restraint 2 to retract it.
Do the same for the second protective
bar. If you are not familiar with any of
the procedures, consult your BMW
center.
Have the rollover protection system
checked out by your BMW center after
it has been inadvertently triggered.
Do not move the convertible top
under any circumstances if the
rollover protection system has
extended.
Do not use the rear head restraints as
storage shelves.
Absolutely no modifications are to be
made to any of the rollover protection
system's individual components or any
of its wiring.
Only your BMW center is to carry out
any work on the rollover protection
system.
Work done on the system that is carried
out improperly could lead to failure in
an emergency or accidental activation.
Regarding having the system checked
to ensure long-term operation: be scru-
pulous in adhering to the Service
Interval Display for maintenance inter-
vals. Every 2 years at the latest, the roll-
over protection system must be
inspected at a BMW center.<

Starting the engine Switching off the engine
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.
Do not allow the engine to warm up by
leaving it running while the vehicle
remains stationary. Instead, drive off
immediately at a moderate engine
speed.<
If the engine does not start on the first
attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at extremely low tempera-
tures of roughly +5 7 (Ð15 6) or below
and at altitudes of over 3,300 ft
(1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds)
>Press the accelerator pedal halfway
down while engaging the starter.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from discharging,
always deactivate electrical devices
that are not in use. Switch the ignition
off when the vehicle is not being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can lead to catalyst
damage.<
Turn the ignition key to position 1 or 0.
You should never remove the igni-
tion key when the vehicle is in
motion, as the steering lock could
engage.
When you leave the vehicle, always
remove the ignition key and engage the
steering lock.
Vehicles with manual transmission:
Always engage the parking brake when
parking on hills and slopes, as first gear
or reverse may not provide adequate
resistance to rolling.
Vehicles with automatic transmission:
Place the selector lever in "P."<

Fuel gauge Temperature gauge Service Interval DisplayOnce the indicator lamp stays on
continuously, there are still approx.
2 gallons (8 liters) of fuel in the fuel
tank.
For fuel tank capacity refer to page 147.
Certain operating conditions (such as
those encountered in mountainous
areas) may cause the needle to fluc-
tuate slightly.
Please refuel early, since driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.<
When you switch on the ignition, the
indicator lamp lights up briefly as an
operation check.
BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on during normal
vehicle operation: the engine has over-
heated. Shut off the engine immediately
and allow it to cool down.
Checking coolant level, refer to
page 123.Between the blue and red zonesNormal operating range. The needle
may rise as far as the edge of the red
sector in normal operation.
Remaining distance to serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The next service due appears with the
message OIL SERVICE or INSPEC-
TION, together with the distance
remaining in miles (kilometers) before
the next scheduled service.
The computer bases its calculations
of the remaining distance on operating
conditions in the preceding period.
A flashing message and a "Ð" in front of
the number mean that the service
interval has already been exceeded by
the distance shown on the display.
Please contact your BMW center for an
appointment.

Dynamic Stability Control (DSC)
*
To switch DSC off/activate ADBPress the DSC button briefly; the indi-
cator lamp comes on and stays on.
DSC is deactivated; ADB is operational.
In the following rare situations, it may
prove useful to deactivate the ADB for a
brief period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>When driving on snow-covered
grades, in deep snow, or on a snow-
covered surface that has been
packed down from being driven on
>When driving with snow chains.
Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.
To switch DSC and ADB offHold the DSC button down for at least
3 seconds. The indicator lamp and the
yellow brake warning lamps light up
and remain on continuously.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC
switched on whenever possible. lamp or the indicator lamps will go out.
The laws of physics cannot be
repealed, even with DSC. An
appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.
When ADB is in its standby mode, DSC
is deactivated; DSC does not intervene
to enhance vehicle stability under these
conditions.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
The system responds to sudden, high-
intensity applications of force to the
brake pedal by automatically braking
the vehicle with maximum boost to
achieve the shortest-possible braking
distances during "panic stops." This
system exploits all the benefits of ABS.
Do not reduce the pressure exerted
against the brake pedal until the
braking maneuver has been completed.
DBC is deactivated when you release
the brake pedal.

To ensure that your vehicle continues to
provide maximum economy throughout
an extended service life, we request
that you devote careful attention to the
following instructions.
Engine and differentialThe first 1,200 miles (2,000 km):
Attempt to constantly vary both vehicle
and engine speed during these initial
miles while remembering to avoid
engine speeds in excess of 4,500 rpm
and/or vehicle speeds of over 100 mph
(160 km/h):
Always obey all official speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
After the initial 1,200 miles (2,000 km)
you can gradually increase both engine
and vehicle speeds.
Please remember to observe the same
break-in procedures if either the engine
or the differential is replaced later in the
course of the vehicle's service life.
TiresOwing to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed.
We thus ask you to drive with extra care
during the first 200 miles (300 km).
Always obey all official speed limits.
When the vehicle is operated on
wet or slushy roads, a wedge of
water may form between the tire and
the road surface. This phenomenon is
referred to as aquaplaning, or hydro-
planing, and can lead to partial or
complete loss of traction, vehicle
control and braking effectiveness.
Reduce your speed on wet roads. elapse before the brake pads and
rotors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and an extended service
life later on.
To break-in the separate parking brake
drums, apply the parking brake lightly
when coasting to a standstill (at a traffic
signal, for instance); use caution to
avoid posing a danger to other road
users. You can prevent corrosion in the
drums by periodically repeating this
procedure.
The brake lamps do not come on
when you engage the parking
brake.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
vehicle with the engine off Ð when
towing, for example Ð substantially
higher levels of pedal force will be
required to brake the vehicle. elapse before the clutch starts to
operate at optimum efficiency.
Remember to engage the clutch care-
fully during this initial period.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect tire inflation pressure is
a frequent cause of tire damage.
Tire pressure also has a major effect on
your BMW's handling response.
Be sure to check the tire pressures,
including the space-saver spare tire or
the spare tire, on a regular basis, at
least twice a month and before every
extended journey, refer to page 24.
Otherwise, incorrect tire pressure can
lead to poor handling, to tire damage
and accidents.<
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is 0.063 in (1.6 mm). Tread wear
indicators (arrow) are embedded in the
base of the tire's tread. Their locations
are indicated by the legend TWI Ð Tread
Wear Indicator Ð at various points on
the tire's shoulder. When the tread
reaches a depth of 0.063 in (1.6 mm),
these indicators appear to signal that
the tires have worn to the minimum
legal level. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.
Do not drive on a deflated (flat)
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. The type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it, its
wheels and tires inspected.
