Malfunction in vehicle stability-control
systems
The brake system warning lamp lights
up in red, appearing together with the
indicator lamps for ABS and DSC. A
message appears on the Control Dis-
play. The driving stability control sys-
tems are deactivated. Conventional
braking efficiency remains available
without limitations. While you may con-
tinue, you should remember to proceed cau-
tiously and drive defensively while avoiding full
brake applications. Have the system checked
as soon as possible.

malfunction on Canadian models.
The indicator lamp for DSC lights up; a
message appears on the Control Dis-
play. DSC and DTC are deactivated.
The stability maintenance functions are no
longer available. The vehicle remains in running
order. Have the system checked as soon as
possible.
The warning lamp for the brake system
lights up in yellow; a message appears
on the Control Display. DBC has failed.
Have the system checked as soon as possible.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll and
optimizes vehicle stability during cornering and
evasive maneuvers.
Dynamic stabilizers at the front and rear axles
form the basis for active roll stabilization. Sus-
pension compliance adapts to suit driving con-
ditions, varying from performance-oriented during cornering to smooth and comfort-ori-
ented when the vehicle is proceeding in a
straight line. During vehicle operation, the sys-
tem continuously runs through closed-loop
control cycles lasting only fractions of a second.
The system assumes operational status each
time you start the engine.
Malfunction
The warning lamp lights up and a mes-
sage appears on the Control Display.
There is a malfunction in the system.
Have the system checked as soon as possible.
If there is a malfunction in the system,
please remember to adapt your speed
accordingly, especially in curves. The suspen-
s i o n w il l b e n o t i c ea b ly s o f t e r a n d t h e v e h i cl e w il l
display a greater tendency to tilt during corner-
ing and in crosswinds. If a message stating that
you should stop appears on the Control Display,
stop and switch off the engine as soon as pos-
sible. In this case the oil level in the reservoir
may have dropped below the minimum, possi-
bly owing to a leak in the hydraulic system. Do
not continue driving. Contact your BMW cen-
ter.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels
change. This change is detected and is
reported as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
Perform the initialization immediately
after correcting the inflation pressure,

Brake Force Display
The Brake Force Display lights up in two stages
depending on how strongly you brake.
>Normal braking: the brake lamps and the
center brake lamps light up.
>Forceful braking or braking with ABS: the
illuminated area of the rear brake lamps also
increases.

Portable phone in the vehicle
BMW discourages the use of mobile
communications devices, e. g. portable
phones, inside the vehicle without a direct con-
nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
This feature is controlled by two photocells in
the inside rearview mirror. One is integrated into
the glass of the mirror, while the other is located
at an offset position on the rear of the mirror
housing.
For trouble-free operation, keep the photocells
clean and do not cover the area between the
interior rearview mirror and the windshield. Do
not attach stickers of any kind to the windshield
in front of the mirror, either.
Hydroplaning
When driving on wet or slushy roads,
reduce road speed. If you do not, a wedge
of water can form between tires and road sur-
face. This phenomenon is referred to as hydro-
planing, and is characterized by a partial or
complete loss of contact between the tires and
the road surface, ultimately undermining your
ability to steer and brake the vehicle.<
The risk of hydroplaning increases as the tread
depth of the tires decreases, refer also to Mini-
mum tire tread on page173.
Driving through water
Do not drive through water on the road if it
is deeper than 1 ft/30 cm, and then only at
walking speed at the most. Otherwise, the vehi-
cle's engine, the electrical systems and the
transmission may be damaged.<
Using handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
SMG Sequential manual transmission
Start off quickly on slopes. Do not hold
the vehicle on a hill by pressing the accel-
erator, but apply the handbrake instead. Other-
wise overheating can occur in the transmission
region.<
Braking safely
Your BMW is equipped with ABS as a standard
feature. In situations that require it, it is best to
brake with full force. Since the vehicle maintains
steering responsiveness, you can still avoid
possible obstacles with a minimum of steering
effort.
Pulsation of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
Do not drive with your foot resting on the
brake pedal. Even light but consistent
pedal pressure can lead to high temperatures,
brake wear and possibly even brake failure.<
Driving in wet conditions
When roads are wet or there is heavy rain,
briefly exert gentle pressure on the brake pedal
every few miles. Monitor traffic conditions to
ensure that this maneuver does not endanger
other road users. The heat generated in this
process helps dry the pads and rotors to ensure
that full braking efficiency will then be available
when you need it.

Things to remember when driving
108
Hills
To prevent overheating and the resulting
reduced efficiency of the brake system,
drive long or steep downhill gradients in the
gear in which the least braking is required. Even
light but consistent pedal pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<
You can further enhance the engine's braking
action by selecting a lower gear in the automatic
transmission's manual mode, downshifting as
far as first gear on extremely steep stretches,
refer to page56. This strategy helps you avoid
placing excessive loads on the brake system.
Never drive with the clutch pressed or
allow the vehicle to coast with the trans-
mission in Neutral – or with the engine switched
off – there is no engine braking when the trans-
mission is in Neutral, and no power-assist for
brakes and steering when the engine is not run-
ning.
Never allow floor mats, carpets or any other
objects to protrude into the area around the
accelerator and brake pedals and obstruct their
movement.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimum
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
When the vehicle is parked
Condensation forms in the air conditioner sys-
tem during operation, and then exits under the
vehicle.
Traces of condensed water under the
vehicle are therefore normal
.
Before driving into a car wash
To prevent the exterior mirrors on this vehicle
from being damaged, always fold them in by
hand before entering an automatic car wash.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining loading limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, this could
damage the vehicle and produce unstable
vehicle operating conditions.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
1,400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
650 lbs.:
1,400 lbs. minus 750 lbs. = 650 lbs.

sure to escape, then continue turning to
open.
3.The coolant level is correct when the cool-
ant level is between the MIN and MAX
marks, refer to the diagram adjacent to the
filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until there is an audible click.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

Malfunctions
Brake fluid
The warning lamp lights up in spite of
the handbrake being released; a mes-
sage appears on the Control Display:
Stop immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time, a
considerably longer brake pedal travel may be
noticeable. Have the system thoroughly
checked.
Display of the previously described
malfunction on Canadian models.
When you continue driving, an increased
brake pedal path can be necessary, and
significantly longer braking distances might be
required. Please adapt your driving style
accordingly.<
Brake pads
The warning lamp lights up in spite of
the handbrake being released; a mes-
sage appears on the Control Display:
The brake pads have reached their minimum
pad thickness. Have brake pads replaced
immediately.
Display of the previously described
malfunction on Canadian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. As BMW cannot
assess the suitability of other brake pads for
use on your vehicle, we are unable to assume
continued responsibility for the vehicle's oper-
ating safety if non-approved pads are
installed.<

LEDs light-emitting diodes
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare directly into the unfiltered light for
several hours, as this could result in irritation of
the retina.<
Changing wheels
Safety precautions in the event of a flat
tire or wheel change: Park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Lock the steering wheel in straight-ahead set-
ting of the wheels. Apply the handbrake and
engage first gear, reverse gear or selector lever
position P.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a guardrail.
If a warning triangle or portable hazard warning
lamp is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.
