2006 BMW 330XI SEDAN brake light

Technology for driving comfort and safety

Malfunction
The warning lamps for the brake sys-
tem light up in yellow. The drive-off
assistant has failed. The car will not
be held in place after the brake is
released. Have the system checked as soon as
possible.
Canadian models display these warn-
ing lamps.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures
while the car is being driven. The system
reports any significant loss of pressure in one
tire in relation to another.
If a tire loses pressure, its rolling radius
changes, and this in turn alters the speed of
rotation. 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.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external factors, nor can it identify
the gradual loss of pressure that will inevitably
occur in all four tires over a lengthy period of
time.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration>If snow chains are attached
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system while snow chains
are attached.<
iDrive concept, refer to page16.
1.Press the button.
This opens the start menu.
2.Press the controller to open the menu.
3.Select "Vehicle settings" and press the
controller.
4.If necessary, move the highlight marker to
the uppermost field. Turn the controller
until "FTM" is selected and press the con-
troller.
5.Start the engine, but do not start driving.
6.Select "Set tire pressure" and press the
controller.
7.Select "Yes" and press the controller.
8.Start to drive.
"Status: FTM active" reappears in the Con-

Technology for driving comfort and safety
90 tiously and think well ahead. Have the system
checked.
If the warning lamp lights up during the first
engine starting following a power supply inter-
ruption, the system must be activated by being
initialized.
Brake Force Display*
The brake lamps light up in two stages,
depending on how sharply you apply the
brakes.
>Normal braking:
The brake lamps and the center brake lamp
light up.
>Sharp braking:
The illuminated surface of the brake lamps
is enlarged, as long as the rear fog light is
not switched on.
Airbags
The following airbags are located under the
marked covers:
1Front airbags
2Head airbags
3Side airbags
Protective action
Observe the adjustment instructions on
page40 to ensure the best possible per-
sonal protection.<
The front airbags help protect the driver and
front passenger by responding to frontal impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
head air bag supports the head.
The airbags will purposely not be activated by
every collision, e.g. not by more minor acci-
dents, certain roll-over situations and rear-end
collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way. Do not attach

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*
The automatic dimming feature of the interior
and exterior mirrors
* is controlled by two photo
cells in the interior rearview mirror. One photo
cell is in the mirror frame, see arrow; the other is
on the back of the mirror.
In order to ensure that the system functions
correctly, keep the photo cells 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.
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 situation, known as hydroplaning,
means that the tire can completely 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 page195.
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.<
Use the handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page87.
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 of the brake pedal, combined with
sounds from the hydraulic circuits, indicate that
ABS is in its active mode.
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.
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 brake pressure can lead to
high temperatures, brake wear and possibly
even brake failure.<

Engine oil
The engine oil consumption is dependent on
driving style and driving conditions.
Checking oil level
Your car is equipped with an electronic oil-level
monitor.
For a precise measurement and display of the
oil level, it is necessary that the engine be at
operating temperature, e.g. after uninterrupted
driving for at least approx. 6.5 miles/10 km. You
can have the oil level displayed while you are
driving, or while the vehicle is at a standstill on a
level surface and the engine is running.
Display in the instrument cluster
1.Lightly push button 1 in the turn indicator
stalk up or down repeatedly until the appro-
priate symbol is shown in the display,
accompanied by the word "OIL".
2.Press button 2 in the turn indicator stalk.
The oil level is checked and the reading dis-
played.

to open.
3.The coolant level is correct if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next 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.
Brake system
Malfunctions
Brake fluid
The warning lamps light up in red
even though the handbrake has been
released. A message 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 checked without
delay.
Display of this malfunction on Cana-
dian models.
If you continue to drive the car, you may
have to depress the brake more and brak-
ing distances may be significantly longer.
Please adapt your driving style accordingly.<
Brake pads
The warning lamps light up in red
even though the handbrake has been
released. A message appears on the
Control Display. The brake pads have
reached the safe limit for pad wear. Have brake
pads replaced immediately.
Display of this malfunction on Cana-
dian models.
For your own safety: use only brake pads
that BMW has approved for the corre-
sponding vehicle model. BMW is unable to
assess the suitability of brake pads it has not
approved and therefore cannot guarantee their
safety.<
