Safety and Security Driving and safety systems 4-ETS Warning! The 4-ETS improves vehicle's ability to utilize available traction, especially under slippery road conditions. The brakes are applied to the spinning wheel and power is allowed to flow to the wheel(s) with traction. The 4-ETS function is available between vehicle speeds of 0 mph (km/h) and 37 mph (60 km/h). The ESP warning lamp v in the instrument cluster ( page 24) comes on when you switch on ignition ( page 35). It goes out when the engine is running. The ESP warning lamp v starts to flash at any vehicle speed, as soon as the tires lose traction and the wheels begin to spin. G ! The engine must be shut off when the parking brake is being tested on a brake test dynamometer. the vehicle is being towed with one axle raised. Otherwise, the 4-ETS will engage the brakes and seriously damage the brake system. For more information, see "Practical hints" ( page 293). When you see the ESP warning lamp v flashing in the instrument cluster, then proceed as follows: While driving off, apply as little throttle as possible. While driving ease up on the accelerator. Adapt your speed and driving style to the prevailing road conditions. Failure to observe these guidelines could cause the vehicle to skid. The 4-ETS cannot prevent accidents resulting from excessive speed. 83
