Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "

l

" are tested for
proper functioning whenever the igni-
tion key is turned. They each light up
once for different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it will light up while the vehicle is mov-
ing. You will see how to react to this
below.

Red: stop immediately

Battery charge

l
The battery is no longer being
charged. There is a malfunction
of the alternator V-belt or in the charg-
ing circuit of the alternator. Please con-
tact the nearest BMW center.
If the ribbed V-belt is defective, do
not continue driving. The engine
could be damaged due to overheating.
If the V-belt is defective, increased
steering effort is also required.<
Engine oil pressure
l
Stop the vehicle immediately
and switch off the engine. Check
the engine oil level and refill as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving. If you do
so, the engine could be damaged
because of inadequate lubrication.<
Tire Pressure Control (RDC)
* l
In addition, an acoustic will go
off: a tire failure has occurred.
Reduce vehicle speed immediately to
stop the vehicle. Avoid hard brake ap-
plications. Do not oversteer.
For additional information, refer to
page 89.
Brake hydraulic system l
If the lamp comes on when the
parking brake is not engaged,
check the brake fluid level. Before driv-
ing further, be sure to read the notes on
pages 117 and 136.

The fully automatic convertible top
*
The fully automatic convertible top
combines assured protection from the
weather with a one-touch operation.
Here are a few tips to ensure that you
get the most enjoyment out of driving
your convertible.
It is advisable to close the convertible
top when the vehicle is parked. The
closed convertible top not only protects
the passenger compartment from un-
foreseeable damage from the weather,
it also provides a certain degree of theft
protection. In addition, keep valuables
only in the locked luggage compart-
ment, even with the convertible top
closed.
Never mount a roof-mounted luggage
rack on the convertible top.
To prevent damage, do not operate the
convertible top at temperatures below
14 7 (–10 6).
To conserve the battery, operate the
convertible top only with the engine
running if at all possible.
The convertible top operation is
completely automatic. In rare in-
stances, some manual support may be
necessary (see Note in next column
but one).
Operate the convertible top only when
the vehicle is stationary. Do not start to
drive while operating it, either, because
the procedure could be interrupted
when the top hits certain positions.
A partially open convertible top can
lead to damage or injury.
If you initiate convertible top operation
with the vehicle stationary and then
start driving, e.g. at a traffic light, you
can completely carry out the initiated
operation. To do this, press and hold
the corresponding button again.
Give the respectively applicable traffic
rules preference during convertible top
operation, as otherwise you will be in
violation of the law.
Remove any foreign objects from the
windshield frame before closing the
convertible top, otherwise, they could
hinder the opening and closing of the
convertible top.
Do not place any objects on the con-
vertible top, since they would fall off
when the convertible top is operated
and cause damage or injuries.
While driving, always close the rear
power windows first, or close all 4 win-
dows at the same time, otherwise the
windows may not shut tightly at higher
speeds.cDo not reach into the convertible
top mechanism during opening
and closing. Keep children away from
the moving parts of the convertible top
during operation.
The automatic process is immediately
interrupted if the button for actuating
the convertible top is released. The pro-
cess can be continued in the direction
desired by pressing the switch.c
If the convertible top has been
stored in the convertible top com-
partment for an extended period of
time, e.g. during the winter months be-
cause the hardtop
* has been used, it
may be necessary to manually support
the top when closing it automatically for
the first time:
Should the convertible top stop shortly
before it reaches the end of the closing
operation, press from outside against
the front of the convertible top frame
while pressing the switch to help the
top along until it begins moving again
on its own.c

Convenience operation from the
driver's door lock>To open: with the door closed, turn
the key to the "Unlock" position and
hold it
>To close: with the door closed, turn
the key to the "Lock" position and
hold it.
Releasing the key stops the movement.
For safety reasons, to keep the closing
process in view, you cannot use the re-
mote control for convenience operation.
At higher speeds, the lower air
pressure in the passenger com-
partment may create a vacuum and
cause the convertible top to start flut-
tering. Increase the air supply via the
ventilation controls so that a vacuum
does not occur in the vehicle.c
The wind deflector cuts down air turbu-
lence within the passenger area, thus
affording a pleasant ride, even at higher
speeds. It is delivered in a protective
casing, and because of its minimal size,
can easily be stowed in the luggage
compartment.Installation1 Take the wind deflector out of its
protective casing

Automatic transmission with Steptronic
*
In the following situations, the Step-
tronic "thinks" for you in the manual
mode:
>In order to prevent the engine from
overrevving, the transmission shifts
automatically to the next higher gear
just before the RPM cutoff point
>If you do not do anything to inter-
vene, it will automatically downshift
at lower speeds
>In the "Kickdown" mode, the trans-
mission shifts down to the lowest
gear which is possible, depending on
the engine speed
>Depending on the situation – when
driving in adverse winter conditions,
for example – you may also start out
in 2nd or 3rd gear.

Bring the vehicle to a stop. Move the
transmission selector lever to "P". Set
the parking brake and turn the engine
off (ignition key to position 0).
Wait a few seconds, then start the
engine.
If the indicator lamp goes out after a
few seconds, normal transmission per-
formance has been restored. You may
continue to drive as usual. If the indica-
tor lamp does not go out, you can put
the selector lever in all positions. How-
ever, the vehicle will now only operate
in 3rd and 4th gear.
If this happens, avoid extreme engine
loads and consult the nearest BMW
center.
Do not work in the engine com-
partment when a drive gear (for-
ward or reverse) is engaged. If you do
this, the vehicle could move.<

Dynamic Stability Control (DSC) The conceptDSC helps maintain vehicle stability,
even in critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, the system recog-
nizes unstable vehicle conditions (un-
dersteering or oversteering, for exam-
ple) and helps hold the vehicle on a
sure course by intervening via the
engine and by braking intervention at
the individual wheels.
The system activates automatically
each time you start the engine.46cus012
Indicator lamp
The indicator lamp in the instru-
ment cluster goes out shortly
after you switch on the ignition.
Refer to pages 21 and 22.
Indicator lamp flashes:
The system is active and governs drive
force and braking force.
If the indicator lamp fails to go out after
the engine is started, or if it comes on
during normal driving and stays on:
There is a system malfunction or the
system was deactivated with the but-
ton. You can continue to drive the vehi-
cle normally, but without DSC. Please
consult your BMW center for repairs.
To deactivate the systemPress the button, the indicator lamp
comes on.
The illustration depicts the arrangement
of the buttons if the vehicle is fully
equipped. This may vary, depending on
the equipment actually installed.
When the DSC is deactivated, you are
operating the vehicle in the conven-
tional drive mode.
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period:
>When rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
Refer also to page 118.To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be re-
pealed, even with DSC. Any con-
sequences arising from traction loss
due to excessive vehicle speed remain
the responsibility of the driver. For this
reason, do not take risks by using the
additional safety margin provided by
the system as an excuse.<
For additional details concerning DSC,
please refer to the chapter describing
"Advanced technology" on page 173.

Automatic climate controlAir supply

By pressing the left or right half
of the button, you can vary the
air supply. By doing this, you switch off
the automatic control for the air supply.
Nevertheless, the automatic air distri-
bution remains unchanged.
When you set the lowest blower speed
by pressing the left half of the button,
all of the displays are canceled: the
blower, heater and air conditioner are
switched off, and the air supply stops.
You can reactivate the system by
pressing any button of the automatic
climate control.
Defrost the windshield and side
windows
This program quickly removes
ice and condensation from the
windshield and side windows.
Air conditioner
The air is cooled and dehumidi-
fied and – depending on the tem-
perature setting – rewarmed when the
air conditioner system is switched on.
Depending on the weather, the wind-
shield may fog over briefly when the
engine is started.
Use the button to switch the air condi-
tioner off when outside air temperatures
are below approx. 41 7 (+5 6). This
will help to prevent the windows from
fogging over.
If the windows fog over after switching
the air conditioner off, switch it back on.
Condensation forms in the air
conditioner system during opera-
tion, which then exits under the vehicle.
Traces of condensed water of this kind
are thus normal.<
Automatic recirculated air
control (AUC)
If there are unpleasant odors or
pollutants in the outside air, you
can temporarily block the air flow from
the outside. The system then recircu-
lates the air already within the vehicle.
By repeated actuation of the button,
you can select three different operating
modes.
>Indicator lamps off: fresh air flows
into the vehicle
>Left-hand indicator lamp on – AUC
mode: the system detects pollutants
in the outside air and responds by
deactivating the outside air flow as
required. The system then recircu-
lates the air already within the vehicle.
Depending on air quality require-
ments, the system automatically
switches between outside air supply
and recirculation of the air already
within the vehicle
>Right-hand indicator lamp on: the
flow of outside air is permanently
blocked. The system recirculates the
air already within the vehicle.
If the windows fog over in the
recirculated air mode, switch this
mode off and increase the air supply
as required.<

Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear, and possibly
to brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as aquaplaning
or hydroplaning. It is characterized by a
partial or complete loss of contact be-
tween the tires and the road surface.
The ultimate results are loss of steering
and braking control.
Driving through water:
Do not drive through water over the
road if it is deeper than 1 ft (30 cm), and
then only at walking speed, otherwise
the engine, electrical system and trans-
mission could be damaged.
Clothes hooks (when hardtop
* is
mounted):
When suspending clothing from the
hooks, ensure that they will not obstruct
the driver's vision. Do not hang heavy
objects on the hooks. If you do, they
could cause personal injury during
braking or evasive maneuvers.<
The catalytic converter reduces harmful
exhaust emissions. It is designed for
use with unleaded fuel only.
Even minute quantities of lead would be
enough to permanently damage both
the catalytic converter and the system
oxygen sensor.To ensure efficient, trouble-free engine
operation and to avoid potential damage:>Be sure to comply with the scheduled
maintenance requirements
>Fill the fuel tank well before it is
empty
>Tow-start only when the engine is
cold. If you attempt to tow-start with
a warm engine, unburned residual
fuel in the catalytic converter could
ignite and cause damage. It is better
to jump-start the vehicle with outside
assistance
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables
disconnected.Be sure to observe the instruc-
tions above to prevent unburned
fuel from reaching the catalytic con-
verter, otherwise, the catalytic con-
verter could overheat and be damaged.
High temperatures occur in every vehi-
cle equipped with a catalytic converter.
Heat shields are installed adjacent to
some sections of the exhaust system.
Never remove these shields; do not
apply undercoating to their surfaces.
When driving, standing at idle, and
parking the vehicle, take extra care to
avoid contact between the exhaust sys-
tem and flammable materials (grass,
hay, leaves, etc.). Such contact could
lead to a fire, resulting in serious per-
sonal injury and property damage.<

Winter operationWinter is often accompanied by rapid
changes in weather, requiring not only
a different driving style, but also certain
preparations to the vehicle itself to en-
sure that your vehicle operates safely
and trouble free throughout the winter
months.CoolantBe sure that the coolant mixture con-
tains the year-round ratio of 50:50
water and antifreeze/corrosion protec-
tion. This mixture provides protection
against freezing down to approx. –34 7
(–37 6). Replace the coolant every four
years.LocksBMW door lock deicer can be used to
free them if frozen. This deicer also
contains lubricant.
After its use, treatment with BMW lock
barrel grease is recommended.
Rubber seals and components To prevent the weather stripping from
freezing, apply a spray-on rubber treat-
ment or silicone spray to the door, hood
and luggage compartment lid seals.
A full range of car care products is
available from your BMW center. both summer and winter tires. Mount
them in pairs on the rear wheels only
and comply with the manufacturer's
safety precautions. Do not exceed a
maximum speed of 30 mph (50 km/h).
In this type of exceptional situation
where the snow chains are mounted,
deactivate the DSC. Refer to page 88.
Starting offWhen starting off from a full stop in
deep snow or when "rocking" the vehi-
cle to free it, it may be effective to
deactivate the DSC system for a short
period. Refer to page 88.Driving on low-traction road
surfacesUse smooth, gentle pressure to control
the accelerator pedal. Avoid excessive
engine speeds and shift to the next
higher gear at an early point. On down-
hill grades or slopes, shift down to the
next lower gear at an early point. Main-
tain an adequate distance between
yourself and the vehicle ahead.

Winter operationBrakesWinter road conditions substantially
reduce the amount of traction available
between the tires and the road surface.
Keep this in mind, because the braking
distance increases substantially.
ABS is intended to prevent the wheels
from locking during brake applications,
thus helping to maintain vehicle stability
and steering response.
If the ABS does not respond in a critical
braking situation and the wheels lock,
reduce the pressure on the brake pedal
until the wheels just start to roll again
while still maintaining enough force to
continue braking. Then increase the
pressure, reduce the pressure when the
wheels lock, reapply pressure, etc.
This staggered braking procedure will
reduce stopping distances while help-
ing you maintain steering control.
You can then attempt to steer around
hazards after you have reduced pres-
sure on the brake pedal.Do not shift down on slick road
surfaces. Doing so could cause
the rear wheels to lose traction and
skid, which could result in the loss of
vehicle control.<
Depress the clutch during hard
braking on road surfaces that pro-
vide only poor or uneven traction.<
Skid control Depress the clutch and release the ac-
celerator pedal, or place the selector
lever of the automatic transmission into
the "Neutral" position. Countersteer
carefully and attempt to regain control
of the vehicle.
ParkingEngage first or reverse gear. If your
vehicle is equipped with an automatic
transmission, place the selector lever in
Park. On vehicles with manual trans-
mission, also apply the parking brake
when parking on inclined surfaces. In
order to prevent the parking brake pads
from locking due to frost or corrosion,
dry them by gently applying the parking
brake as the vehicle is coming to a
stop. Make sure that following traffic
is not endangered.
The brake lamps do not come
on when the parking brake
is applied.<
