Driving tips Braking applications triggered automatically by ESP® may otherwise seriously damage the brake system. If your brake system is subject only to moderate loads, you should test the functionality of your brakes at regular intervals by pressing firmly on the brake pedal at high speeds. This improves the grip of the brake pads. The wear of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and operating conditions. For this reason, it is impossible to state a mileage that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your authorized Mercedes-Benz Center. 139 G Warning Make sure that you do not endanger other road users when you apply the brakes. Parking brake G Warning! While performing this procedure please assure that the vehicle is stopped before applying the parking brake. Otherwise the rear wheels could lock up. You could lose control of the vehicle and cause an accident. In addition, the vehicle's brake lights do not light up when the parking brake is engaged. Make sure not to endanger any other road users when you engage the parking brake. You can find a description of Brake Assist (BAS) on (Y page 56). High-performance brake system for AMG vehicles The high-performance brake system is installed only on the G 55 AMG. G Warning New vehicle brake pads and discs, and replacement brake pads and discs may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period. Excessive high-demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. To maintain the braking effect of the parking brake between the service intervals, you can briefly apply the parking brake while driving. X Drive about 20 mph (30 km/h) on a dry, even road. X Pull the parking brake upwards with the release button depressed (Y page 135), until the vehicle brakes noticeably. X Hold the lever in this position for approximately ten seconds and then push it all the way down again. ! Do not drive faster than 25 mph (40 km/h). Otherwise, you could damage the brakes. The high-performance brake system is designed for heavy loads. This may lead to noise when braking.
