Safety and security Driving safety systems ! The ESP® will only function properly if you use wheels of the recommended tire size as specified in the "Technical data" section of this Operator's Manual. i The cruise control switches off automatically when the ESP® engages. For more information, see the "Practical hints" section (Y page 272) and (Y page 300). Electronic Traction System (ETS) G Observe Safety notes, see page 58. The ETS (Electronic Traction System) is a component of the ESP®. The ETS improves the vehicle's ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. When you switch off the ESP®, the ETS is still enabled. Switching off the ESP® G Warning! The ESP® should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. Do not switch off the ESP® when a spare wheel is mounted. To improve the vehicle's traction, switch off the ESP® in driving situations in which it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: Rwhen Rin Rin When you switch off the ESP® Rthe Rthe ESP® does not stabilize the vehicle engine output is not limited, which allows the drive wheels to spin and thus cut into surfaces for better grip ETS will still apply the brakes to a spinning wheel ESP® continues to operate when you are braking cannot activate the cruise control cruise control switches off if activated Rthe Rthe Ryou Rthe driving with snow chains deep snow sand or gravel i When the ESP® is switched off and one or more drive wheels are spinning, the ESP® warning lamp v in the instrument cluster flashes. However, the ESP® will then not stabilize the vehicle. G Warning! Switch on the ESP® immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESP® will not stabilize the vehicle when it is starting to skid or a wheel is spinning. 61
