text version of content this owner's manual page from owners manual to the vehicle Mercedes C, year of production 1993 - 2001:

Acceleration Slip Regulation (ASR) The acceleration slip regulation will engage at all vehicle speeds, if one or both drive wheels begin to lose traction and spin in acceleration. While engaged, the yellow warning lamp in the speedometer dial flashes. With the acceleration slip regulation engaged, the brake is applied to the spinning drive wheel until slip is brought under control. If both drive wheels spin, the brake is applied to both drive wheels and simultaneously, engine torque is limited, to improve the vehicle's driving stability. As traction on the road surface increases, thus allowing acceleration without slip, the allowable engine torque also increases again and the brake is no longer applied to drive wheels. Important ! If the ASR warning lamp flashes, adapt your speed and driving to the prevailing road conditions. Caution! If the vehicle is towed with the front axle raise d (see Towing the vehicle in Index), the engine must be shut off (electronic key in steering lock position 0 or 1). Otherwise, the ASR regulation will immediately be engaged and will apply the rear wheel brakes. Notes: The indicator lamp for the ASR is combined with that of the BAS The yellow BAS/ASR malfunction indicator lamp in the instrument cluster and the yellow ASR warning lamp in the speedometer dial come on with the electronic key in steering lock position 2. They should go out with the engine running. If the BAS/ASR malfunction indicator lamp comes on with the engine running, a malfunction has been detected in either system. Pressing the accelerator pedal will require greater effort. Only partial engine output will be available. If the BAS malfunctions, the brake system functions in the usual manner, but without BAS. Have the BAS or ASR checked at your authorized Mercedes-Benz dealer as s oon as possible. With the ABS malfunctioning, the ASR is also switched off. Driving the vehicle with varied size tires will cause the wheels to ro tate at different speeds, therefore the ASR may activate (yellow ASR warning lamp in speedometer dial comes on). For this reason, all wheels, including the spare wheel, must have the same tire size. When testing the parking brake on a brake test dynamometer, the engine must be shut off. O therwise, the ASR will immediately be engaged and will apply the rear wheel brakes. In winter operation, the maximum effectiveness of the ASR is only achieved with Mercedes-Benz recommended M+S rated radial-ply tires and/or snow chains. ASR Control Switch ASR control switch located in center console To improve the vehicle's traction when driving with snow chains, or starting off in deep snow, sand or gravel, press the upper half of the ASR switch. The ASR warning lamp, located in the speedometer dial, is continuously illuminated. With the ASR sy stem switched off, the engine torque reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ASR is unavailable. Adapt your speed and driving to the prevailing road conditions. A portion of the ASR system remains active, even with the switch in the OFF position. If one drive wheel loses traction and begins to spin, the brake is applied until the wheel regains sufficient traction. The traction control engages at vehicle speeds up to approximately 24 mph (40 km/h), and switches off at 50 mph (80 km/h). No te: Avoid spinning of one drive wheel. Doing so may cause serious damage to the drive train which is not covered by the Mercedes-Benz Limited Warranty. The ASR warning lamp, located in the speedometer dial, starts to flash at any vehicle speed as soon as the tires lose traction and the wheels begin to spin. To return to the enhanced vehicle stability offered by ASR: press lower half of the switch (the ASR warning lamp in the speedometer dial goes out). Important! If the ASR warning lamp flas hes: during take-off, apply as little throttle as possible, while driving, ease up on the accelerator.
