Congratulations, and thank you for choosing a BMW. Thorough familiarity with your vehicle will provide you with enhanced control and security when you drive it. [. . . ] Such contact could cause a fire, resulting in personal injuries and property damage. <
The catalytic converter reduces harmful exhaust emissions. Even minute quantities of lead would be enough to permanently damage both the catalytic converter and the system's oxygen sensor. To ensure efficient, trouble-free engine operation and avoid potential damage: > Be sure to comply with the scheduled maintenance requirements. Tow-starting when the engine is warm could cause unburned fuel to ignite in the catalytic converter, resulting in significant damage. It is better to start the vehicle with an outside starting aid.

Antilock Brake System (ABS)
The concept
ABS increases active safety by preventing the wheels from locking when braking. When the front wheels slide, the driver loses steering control over the vehicle. Traction loss at the rear wheels can cause the rear end to break into an uncontrolled skid. The system can achieve the shortest braking distances possible under most conditions (on straight-aways and in curves, on asphalt, ice, wet road surfaces, etc. ). ABS is designed to meet two essential requirements during every brake application: > To help provide vehicle stability. > Assured ability to steer and maneuver on the various road surfaces (asphalt, concrete, dirt, wet conditions, snow, ice).
99n The ABS closed-loop control circuit cycles in fractions of a second. The pulsation at the brake pedal, together with sounds generated by the hydraulic control system, indicate to you that the vehicle is approaching its maximum braking range. It is a reminder to you that you must adapt the vehicle's road speed to existing road conditions. On road surfaces that have a loose surface layer on a firm base with good traction (on gravel, deep sand or snow, for example), braking distances may be longer than with locked wheels. However, ABS continues to provide enhanced vehicle stability and steering response under these conditions.
The system is operative once the vehicle exceeds a speed of approx. Therefore, the wheels could theoretically tend to lock in the final phase of a braking action, but this is insignificant in actual practice. If you are in a situation which requires full braking, you will exploit the full benefits of the ABS system if you apply maximum brake pressure ("panic stop"). Since the vehicle maintains steering responsiveness, you can avoid possible obstacles with a minimum of steering effort, despite the full brake application.

Brake System (ABS)
In the event of a fault
The ABS warning lamp comes on, refer to page 21. The brake system then reverts to conventional operation as on vehicles without ABS. However, have the brake system checked by your BMW center as soon as possible. To prevent undetected defects and cumulative faults from adversely affecting the brake system, refer any problems to your BMW center at the earliest opportunity. [. . . ] This tends to further reduce the tendency to slide under the lap belt.
