Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
by
+ are tested for proper functioning whenever
the key is turned. They each light up once for
different periods of time.
If a malfunction occurs in one of the monitored
systems, the corresponding lamp does not go
out after the engine has started, or it lights up
again while the vehicle is in motion. You can find
more information about each system on the
specified pages.

by your BMW center or at a workshop that
works according to BMW repair procedures
with correspondingly trained personnel. Other-
wise, it is not guaranteed that the safety devices
will function properly.<
Mirrors
Exterior mirrors
The passenger's mirror is more convex
than the driver's mirror. The objects seen
in the mirror are closer than they appear. Do not
gauge your distance from traffic behind you on
the basis of what you see in the mirror; other-
wise there is an increased risk of an accident.<

Manual adjustment
The mirrors can also be adjusted manually:
press on the edges of the lens.
Folding mirrors in or out*
The mirrors can be folded in or out up to a road
speed of approx. 6 mph/10 km/h by pressing
button3. This can be useful on narrow roads,
for example, or to reset the mirrors to their cor-
rect positions after they were folded in.
Automatic heating*
Both exterior mirrors are automatically heated
when the engine is running or the ignition is
switched on.
Interior rearview mirror
Turn the knob to reduce glare from the head-
lamps of cars behind you when driving at night.
Interior and exterior mirrors with
automatic dimming feature*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. In the Road-
ster, one is located in the top of the mirror
frame, see arrow. In the Coupe, it is located at
the bottom of the mirror frame. The other photo
cell is on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photocells clean, do not
cover the area between the interior rearview
mirror and windshield, and do not affix adhesive
labels or stickers of any kind to the windshield
directly in front of the mirror.

Technology for driving comfort and safety
Driving stability control
systems
Your BMW is equipped with a s eries of systems
that help maintain driving stability even in
adverse driving situations.
Antilock Brake System ABS
ABS keeps the wheels from locking during
braking. Steering stability is maintained even
during full brake applications. In this way, active
safety is enhanced.
ABS is operational each time the engine is
started. Braking safely, refer to page75.
Electronic brake-force distribution
The system controls brake-force application at
the rear wheels in order to obtain increased sta-
bility in the vehicle's braking response.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. At the same time, the benefits of the ABS
are also exploited.
As long as you want full braking to continue, do
not reduce pressure on the brake.
Dynamic Stability Control DSC
DSC prevents slip at the drive wheels while
starting off and accelerating the vehicle. DSC
also recognizes unstable vehicle conditions,
such as fishtailing or nose-diving. In these
cases, and subject to physical limits, DSC helps
to keep the vehicle on a steady course by
reducing engine speed and by applying brakes
at individual wheels.
The laws of physics cannot be repealed
even with DSC. It will always be the
driver's responsibility to drive in a manner that
matches road conditions. Therefore, do not limit the additional safety margin by practicing
risky driving.<
Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamp for DSC lights up in the instrument
cluster. Dynamic Traction Control DTC and
DSC have been deactivated simultaneously. No
more interventions to increase stability and for-
ward momentum are carried out.
To enhance vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button again; the indicator lamp goes
out in the instrument cluster.
Checking
The indicator lamp flashes:
DSC controls the drive forces and
brake forces.
The indicator lamp is lit:
DSC has been deactivated completely.
Dynamic Traction Control DTC
DTC is a variant of the DSC in which forward
momentum is optimized for special road condi-
tions, e.g. snow-covered roads that have not
yet been cleared. The system ensures maxi-
mum forward momentum, but driving stability is
limited. Therefore, drive carefully in accordance
with conditions.

Technology for driving comfort and safety
52 In the following exceptional circumstances, it
may be effective to activate the DTC for a short
period:
>When driving on snow-covered grades, in
slush or on uncleared, snow-covered roads
>When rocking the vehicle or starting off in
deep snow or on loose surfaces
>When driving with snow chains
Activating DTC
Press the button briefly; the DTC indicator lamp
lights up in the instrument cluster.
Checking
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
Malfunction in the driving stability
control systems
Have the system checked as soon as possible.Drive cautiously, think well ahead and
avoid full brake applications, otherwise
unstable driving conditions could result.<
The vehicle remains operational. Have the sys-
tem checked as soon as possible.
Drive cautiously and think well ahead,
otherwise unstable driving conditions
could result.<
Drive-off assistant
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
1.Hold the car in place by depressing the
brake.
2.Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Depending on vehicle load,
the car may roll backwards a little during this
time span. Drive off without delay after releas-
ing the brake. Otherwise, the drive-off assistant
will no longer hold the car in place after approx.
2 seconds and the car will start to roll back-
wards.< The indicator lamp flashes:
DTC controls the drive forces and
brake forces.
The indicator lamp is lit:
DTC has been activated.
The warning lamp for the brake system
lights up in red, together with the yel-
low indicator lamps for ABS and DSC:
The driving stability control systems
have failed.
Canadian models display these warn-
ing lamps.
The DSC warning lamp lights up
together with the yellow warning lamp
for the brake system:
DSC, including DTC and DBC, are
malfunctioning.
Canadian models display these warn-
ing lamps.

Special operating instructions
Break-in procedures
Moving parts need to be given some time until
they can interact smoothly with one another. To
ensure that your vehicle provides maximum
economy throughout a long service life, we
request that you observe the following:
Always obey all official speed limits.
Engine and differential
Up to 1,200 miles/2,000 km
Drive at varying engine and road speeds, but do
not exceed 4,500 rpm or 100 mph/160 km/h.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kickdown point.
After driving 1,200 miles/2,000 km
Engine and vehicle speeds can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until an initial break-in period has
elapsed. Therefore, drive cautiously during the
first 200 miles/300 km.
Brake system
Brakes require an initial break-in period of
approx. 300 miles/500 km to achieve optimized
contact and wear patterns between brake pads
and rotors. Drive cautiously during this break-in
period.
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. Shift gears carefully during
the break-in period.
After replacing components
The same break-in procedures should be
observed if any of the components mentioned
above have to be renewed in the course of the
vehicle's operating life.
Driving notes
Close the luggage compartment lid/
tailgate
Operate the vehicle only when the lug-
gage compartment lid/tailgate is closed.
Otherwise, exhaust fumes could enter the inte-
rior of the vehicle.<
Should it be absolutely necessary to drive with
the luggage compartment lid/tailgate open:
1.Coupe: close both windows.
Roadster: close all windows if the convert-
ible top is closed.
2.Greatly increase the air flow from the air
conditioning or automatic climate control,
refer to page62 or65.
Hot exhaust system
In all vehicles, extremely high tempera-
tures are generated in the exhaust sys-
tem. Never remove the heat shields installed in
this area, nor apply undercoating to their sur-
faces. When driving, standing at idle or parking
the vehicle, take care to avoid contact between
the hot exhaust system and flammable materi-
als, e.g. hay, leaves, grass, etc. Such contact
could lead to a fire, resulting in serious personal
injury and property damage. Do not touch the
hot exhaust pipes to avoid the risk of injury from
burns.<
Mobile communications in the vehicle
BMW advises against using mobile com-
munications devices, e.g. mobile phones,
inside the vehicle without connecting them
directly to an outside antenna. Otherwise, it

cannot be ruled out that vehicle electronics and
the mobile communications device interfere
with one another. In addition, it is not ensured
that the radio waves emitted during transmis-
sion are directed outside of the vehicle inte-
rior.<
Hydroplaning
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 situation, known as
hydroplaning, means that the tire can com-
pletely lose contact with the road surface, so
that neither the car can be steered nor the brake
be properly applied.<
The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page87.
Driving through water
Drive through water on the road only if it is
not deeper than 1 ft/30 cm, and then only
at walking speed at the most. Otherwise, the
vehicle's engine, the electrical systems and the
transmission may be damaged.<
Moisture inside the vehicle
Make sure that the passenger compart-
ment does not become wet and that liq-
uids are transported in closed containers.
Otherwise, moisture could penetrate and dam-
age electronic components inside the vehicle.<
Use the parking brake on inclines
On inclines, keep the vehicle from rolling
by using the parking brake rather than by
slipping the clutch, which would lead to a high
degree of clutch wear.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. Applying the brakes fully is the most
effective way of braking in situations in which
this is necessary. Since the vehicle maintains
steering responsiveness, you can still avoid possible obstacles with a minimum of steering
effort.
Pulsation at the brake pedal combines with
sounds from the hydraulic circuits to indicate to
the driver that ABS is in its active mode.
Wet roads
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Watch traffic conditions to
ensure that this maneuver does not endanger
other road users. The resulting heat dries the
brake rotors and brake pads. Immediate braking
force is then available if necessary.
Inclines
To prevent overheating and, as a result,
diminished braking effectiveness, drive
down long or steep downhill grades in the gear
that requires the least braking. Otherwise, even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can increase the engine's braking effect by
shifting down, all the way to first gear if neces-
sary. This strategy helps you avoid placing
excessive loads on the brake system. Down-
shifting in manual mode of the automatic trans-
mission, refer to page43.
Never drive with the clutch held down,
with the transmission in idle or with the
engine switched off; otherwise, engine braking
action will not be present or there will be no
power assistance to the brakes or steering.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
pedals, otherwise pedal function could be
impaired.<
Corrosion on the brake rotors
Limited vehicle use, extended periods with the
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle,
low-pressure applications will all increase the
tendency for corrosion to form on the rotors and
contamination to accumulate on the brake
pads. This occurs because the minimal pres-

Correct wheels and tires
BMW recommends using only wheels
and tires that have been approved by
BMW for your particular vehicle model, other-
wise body contact and serious accidents can
result despite the use of the same nominal size,
e.g. due to manufacturing tolerances. If non-
approved wheels and tires are used, BMW can-
not evaluate their suitability, and therefore can-
not be held liable for driving safety.<
You can inquire about the correct wheel/tire
combination at your BMW center.
The correct combination of wheels and tires is
also necessary to ensure reliable operation of
various vehicle systems such as ABS and DSC.
To maintain good handling and vehicle
response, only use tires of a single brand and
tread configuration. After a tire has been dam-
aged, for instance, mount the original wheel and
tire combination again as soon as possible.
Wheels with electronics for the Tire
Pressure Monitor TPM
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPMS electronics; otherwise the
Tire Pressure Monitor would not be able to
detect a flat tire, refer to page54. Your BMW
center will be glad to provide you with more
information.
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Run-Flat Tires
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-Flat Tires for your own safety. In the
event of a flat, moreover, no spare wheel is
available. Your BMW BMW center will be glad to
provide you with more information.
For safety reasons, BMW recommends
that damaged Run-Flat Tires be replaced
rather than repaired.<
Special characteristics of winter tires
BMW recommends the use of winter tires for
operation under winter road conditions. While
all-season tires with M+S designation provide
better winter traction than summer tires, they
generally do not achieve the full performance of
winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and acci-
dents.<
If the car is capable of speeds higher than that
permitted for the winter tires, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store tires in a cool, dry place, protecting them
against light whenever possible. Protect the
tires from contact with oil, grease and fuel. Do
not exceed the maximum tire inflation pressure
indicated on the sidewall of the tire.
Swapping wheels between the axles
BMW advises against moving the front wheels
to the rear wheel positions and vice versa, as
this may impair vehicle handling characteristics.
