HDC Hill Descent Control Self-leveling suspension
*
Using HDC With manual transmission:
Use HDC in first gear and in Reverse
since the engine's braking action is
diminished in the higher gears.
With automatic transmission:
You can use HDC in every drive posi-
tion. In case of a malfunction If the LED in the button goes out during
HDC operation or does not light up
when the HDC is activated:
HDC is temporarily unavailable due to
excessive brake temperature. The warning lamp for the self-
leveling suspension comes on,
or the message SELFLEVEL
SUSP.INACT appears in the Check
Control: there is a malfunction in the
self-leveling suspension.
Stop and inspect the vehicle. If the rear
of the vehicle is visibly lower than the
front, possibly accompanied by a tilt
noticeable when you compare the left
rear with the right rear, please respond
by immediately proceeding to the near-
est BMW Sports Activity Vehicle center.
Drive with appropriate caution in the
meantime. The vehicle has reduced
ground clearance and driving comfort
may be noticeably reduced.
Even when the position of the vehicle is
normal, have the system checked as
soon as possible when a malfunction is
indicated.

Adaptive Head Light
*
High beams/roadside parking lamps
The concept Adaptive Head Light is a variable head-
lamp control system that enables better
illumination of the road surface.
Depending on the steering angle and
other assumptions, the light from the
headlamp follows the course of the
road.Activating Adaptive Head Light
In ignition key position 2, turn
the light switch to the position
'Automatic headlamp control',
refer to page100.
To avoid blinding oncoming traffic, the
Adaptive Head Light
>is not active when driving in reverse
>is active only when pointing toward
the passenger side.
MalfunctionsThe LED next to the symbol for auto-
matic headlamp control flashes. Adap-
tive Head Light is faulty or has failed.
Have the system checked as soon as
possible.

Coolant Brake fluid4. When necessary, slowly add coolant
until the correct level is reached; do
not overfill.
5. Close the cap and tighten snugly.
6. Have the cause of the coolant loss
corrected as soon as possible.
Brake fluid level
If the warning lamp lights up
or
the message CHECK BRAKE
FLUID appears in the Check
Control: stop immediately. The
brake fluid in the reservoir has
fallen to below the minimum
level.
Add brake fluid The brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports Activ-
ity Vehicle center is familiar with the
specifications for factory-approved
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page140.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW Sports Activity Vehicle center.
Refer also to the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach of
children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and cause
serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

OBD interface socketThe interface socket for the Onboard
Diagnostics is located on the left of the
driver's side at the bottom of the instru-
ment cluster and under a cover. The
cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emission
control system for the vehicle's lifetime.
The system monitors emission-related
components and systems for deteriora-
tion and malfunction.
An illuminated indicator lamp
informs you of the need for ser-
vice, not of the need to stop the
vehicle. However, the systems should
be checked by your BMW Sports Activ-
ity Vehicle center at the earliest possi-
ble opportunity. 530us105
Display of the previously
described malfunction in Cana-
dian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a
rather severe level of engine misfire.
When this occurs, you should reduce
speed and consult the nearest BMW
Sports Activity Vehicle center as soon
as possible. Severe engine misfire over
only a short period of time can seriously
damage emission control components,
especially the catalytic converter.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
lamp will light up. If the filler cap is sub-
sequently tightened, the indicator lamp
should extinguish within a few days.<
Event Data Recorders Your vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
have a Subscription Service Agree-
ment for the BMW Assist system, cer-
tain vehicle information may be trans-
mitted or recorded in order to provide
such services.
