Deactivating HDC
after approx. 2 seconds and the car will start to
roll backwards.<
Press the button again; the LED goes out.
HDC is automatically deactivated at speeds
greater than approx. 35 mph/60 km/h.
Flat Tire Monitor FTM*
Using HDC
The concept
In cars with manual transmission:
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
Use HDC in lower gears and in reverse gear.
With automatic transmission:
You can use HDC in any drive position.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. 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.<
Malfunction
The HDC display disappears during HDC oper-
ation, or does not appear:
HDC is temporarily unavailable due to exces-
sive brake temperature, or DSC has failed.
In the following situations, the system could be
delayed or malfunction:
Drive-off assistant
>
>
>
System has not been initialized
The drive-off assistant enables you to drive off
smoothly on uphill gradients. It is not necessary
to use the parking brake for this.
Driving on snowy or slippery road surface
Performance-oriented style of driving: slip
in the drive wheels, high lateral acceleration
1.
Hold the car in place by depressing the
brake.
>
Snow chains are attached
2.
Release the brake and drive off without
delay.
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.<
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Otherwise, the drive-off
assistant will no longer hold the car in place

I need to find out more about my 323i.
I'm having computer cluster.
The 2009 BMW 3-Series is an enthusiast's dream, yet not-quite-perfect safety ratings, smallish rear seats, and some fussy controls might wrinkle potential buyers' noses
