TRACTION CONTROL (OPTION) If you have this feature, this brake only Traction Control complements your anti-lock braking system. Traction Control regulates tire spin during low-speed acceleration and steady driving. The Traction Control Brake-Only System uses the same wheel speed sensors used by your Anti-Lock Brake System (ABS). When wheel slip is detected by the wheel sensors, the electronic control module sends a signal to thebrake pressure modulator to apply pressure pulses to the brakes. Traction is then maximized and your vehicle is enabled to accelerate or continue driving witha controlled amount of tire slip. This low-speed system controls tireslippage and is fullyfunctional until you is reach a speed of 24 mph and then the traction control gradually phased out as your vehicle reaches 30 mph. To keep you informed of changing road conditions the "TRACTIONACTIVE" telltale light will illuminate when the system is activated. Because this is a brake only Traction Control system, itis designed to protect your vehicles powertrain components. The system will temporarily by disabled should the brakes or transaxle reach excessively high temperatures and prolonged use of traction control. The "TRACTION OFF" telltale light in the instrument panel informs you when this system isnot in operation. ELECTRONIC LEVEL CONTROL This keeps your vehicle level. The ignition does nothave to be"ON" for thelevel control to work. The system consists of an electronic height sensor, a small electric air compressor, and air adjustable shock absorbers mounted on the rearof the vehicle. If the system has a slight leak, the air compressor will run frequently for a few seconds each time. For a massive air leak, the air compressor will stay on for approximately 7 minutes. You should see your dealer for service, but you can keep driving your Cadillac.
