ABS (Antilock Brake System) Prevents the wheels from locking up during braking so that the vehicle can continue to be steered. Accessory weight ( page 526) Adaptive Brake Brake system that is coupled with ->ABS, ->ESP and ->BAS. Adaptive Brake takes driver and vehicle characteristics into consideration, thus achieving an optimal braking effect. ADS (Adaptive Damping System) Automatically adapts the optimum suspension damping to prevailing driving conditions. Advanced TPMS* (Tire Pressure Monitoring System) The Advanced TPMS monitors the tire inflation pressure in all four tires. A warning is issued to alert you to a decrease in pressure in one or more of the tires. Tire inflation pressure inquiries are made using the ->Instrument cluster control system. Airmatic Automatically selects the optimum suspension tuning and ride height for your vehicle. Airmatic consists of two components: Adaptive Damping System Vehicle level control Air pressure ( page 526) Alignment bolt Metal pin with thread. The centering pin is an aid used when changing a tire to align the wheel with the wheel hub. A-pillar Front connecting pillar between the roof and the vehicle body (->B-pillar, ->C-pillar).
