Vehicle: 2003 MERCEDES-BENZ CLK320 3.2 V6 GAS
System
Four-wheel ABS uses a control unit, hydraulic actuator and wheel speed sensors to control brake fluid pressure and prevent wheel lock during severe braking conditions,
Basic ABS components are supplemented by an expanded hydraulic unit, a charging pump, a fourth wheel speed sensor and a more comprehensive electronic system for Acceleration Slip Regulation (ASR) and Electronic Traction System(ETS).
Integrated with ABS and traction control systems, Electronic Stability Program (ESP) detects slides and applies brake pressure to individual wheels to help maintain control.

Fuel System Pressure Relief
Do not smoke or allow an open flame of any type when working on or near any fuel system related components. The highly flammable vapor mixtures may ignite, resulting in serious personal injury.
Prior to disconnecting fuel lines, the fuel system pressure must be relieved to prevent accidental fuel spray.
After the battery has been disconnected and reconnected, some abnormal driveability symptoms may occur. The vehicle may need to be driven while it relearns its adaptive strategy.
