  Summary

  Complaint Noises/ squealing from the service brake in various driving situations and ambient conditions Cause Frictional vibrations Remedy AMG brake systems are designed for high loads. This can result in noises under certain operating conditions. These are dependent on speed, brake pressure or ambient conditions such as temperature and air humidity. (Extract from the owner's manual) If customer complaints are received, please proceed as follows: • Check whether, apart from this document, an additional document exists for the model series in question, and if so, work through it • Check whether the complaint can be reproduced and at which axle the noises occur (ideally together with the customer while driving) • Check the friction pairings of the affected axle for wear, mechanical damage or localized overheating damage. a) If this is the case, replace the damaged component parts and assess the brake again with regard to noise. b) If there no obvious visible or technical problems with the brake system, we recommend bedding in the brakes by following the procedure below: • Before trip, the mileage incurred must be clarified with the customer (approx. 50 km) • Select a suitable route • Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 100 km/h to 50 km/h (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1.5 km between brake applications • Finally drive approx. 5 km to allow the system to cool • Reassess the problem If this action fails to deliver the desired success, create a TIPS case with the following information: • Observe SI00.00-P-0086A • Have parts already been replaced? If yes, when and which parts (date, mileage)? • How is the customer's driving profile, and when/where is it reproducible? • Create a video/ sound file • Attach usable pictures of the brake components on the affected axle (important: including the back of the lining)

  Summary

  Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10-P-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down (Picture_01). 6. Glue the new diaphragm onto the intended surface at the service cover (Picture_02). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack (absorption) acts effectively, the headlamp has to be air-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted (Picture_03). 2. The new transparent diaphragm must be correctly bonded (Picture_04). 3. Check headlamp housing for any external damage.

  Summary

  Complaint Headlamp or front fog lamp leaky or fogged Cause Fogging of the headlamps is a natural phenomenon, which can occur under certain climatic conditions. It does not lead to any technical impairment of the headlamp. Headlamps comply with all applicable standards. If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". Remedy Headlamp: Remedy 1 Clearing fogged/condensed LED headlamps and LED rear lamps: 1. Drive vehicle into workshop (temperature higher than +18 °C/+64.4 °F) and connect the exhaust extraction. Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine and connect battery support via a charger. 3. Open the hood or trunk. 4. Switch on the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Clearing fogged/condensed halogen/xenon headlamps: 1. Drive the vehicle into the workshop (temperature higher than +18 °C/+64.4°F). Note: Do not perform an engine wash before the defogging test. 2. Switch off the engine. 3. Open the hood. 4. Switch off the lights. 5. Leave the vehicle in this state for 60 minutes. 6. Check for formation of condensation, a significant reduction in the formation of condensation must be clearly recognizable (thawing progress). Note: If there is no visible reduction in the formation of condensation, check the headlamp for a defect. (See Remedy 2) It is not physically possible to defog the headlamps completely. Fogging does not impair the operation or the service life of the headlamp. Remedy 2 A Damaged headlamp can be identified as follows: 1. Check the headlamp for external damage and that the cover caps and the diaphragm are correctly seated. 2. Check the electrical connectors of the plugs and pins. 3. Check for leak tightness in accordance with LI82.10-P-078307. The test can only be conducted on headlamps. 4. If the headlamp or the rear lamp has any external damage, replace the component part in accordance with the WIS instructions. Note: External damage to the headlamp/rear lamp or faulty seating of the cover caps does not present a warranty or goodwill case. With headlamps, it is possible to install desiccant packs if the problem occurs repeatedly. Open ventilation system: LI82.10-P-064766. Closed ventilation system LI82.10-P-078304

  Summary

  Complaint The garage door hand transmitter cannot be initialized with the integrated garage door opener in the inside rearview mirror. Cause 1. The integrated garage door opener (GDO) is not compatible with the opening system installed in the garage. 2. The garage door drive uses a rolling code system. In contrast to the fixed code system, the LED in the mirror in this case flashes green after programming. 3. When the handheld remote control is initialized with the integrated GDO, the distance between the handheld remote control and the GDO is too long or too short. 4. The maximum programming time of the hand transmitter was exceeded. The hand transmitter switches itself off after 10s to 20s. However, the garage door opener needs up to 30s to learn the code. 5. The maximum programming time of the integrated GDO was exceeded. The integrated GDO has aborted programming unsuccessfully. 6. The GDO cannot be programmed after replacement (See #9). 7. The batteries of the hand transmitter are too weak. 8. A part of the signal was not registered correctly. 9. The GDO is not programmed to US standards. 10. Errors with Chamberlin MyQ, Liftmaster MyQ, or Craftsman AssureLink systems causing loss of synchronization. Remedy Note: The numbering of the remedies refers to the numbering of the causes. 1. Installation of a universal receiver. Order via the Homelink Hotline. 2. In the case of garage door drives with rolling code system, synchronization of the garage door drive must also be performed. 3. Keep the correct distance when initializing! This can vary between 5 and 20 cm depending on the system.

  Summary

  Complaint The range of the integrated garage door opener (GTO) is too short. Cause 1. Vehicles equipped with infrared windows and/or a heated windshield may suffer from complaints involving low transmission power. 2. When comparing the range between the integrated GTO and the garage door hand transmitter, the garage door hand transmitter is tested outside the vehicle. 3. The garage door hand transmitter is being aimed towards the garage door, but the vehicle is in a different position. 4. The garage door drive is old. Remedy 1. The lower level of transmission power is mainly perceived by customers who did not have any infrared windows (code 595) or all-round infrared windows (code 596) or heated windshield (code 597) in their previous model or who have another model without this special equipment in their fleet. The loss in transmission has technical reasons, i.e. a thin metal film is fitted in the windows. Please consider these codes and advise the customer accordingly! Replacing parts does not remedy the problem. 2. Perform the comparison test between the integrated GDO and the garage door hand transmitter under identical conditions. The garage door hand transmitter must be inside the vehicle and must be held at the height of the inside rearview mirror. 3. The customer instinctively aims the garage door hand transmitter towards the door. However, the transmission direction of the integrated GDO depends on the position of the inside rearview mirror, and thus depends directly on the position of the vehicle relative to the receiving antenna of the garage door drive.

  Summary

  To enhance the satisfaction of our customers, avoid further costs of litigation and return focus to its core businesses, Mercedes-Benz USA, LLC (MBUSA) has entered into a settlement regarding claims relating to allegations that the ?590 Mars Red? paint available as an original, exterior color option for certain models of Mercedes-Benz vehicles may experience peeling, flaking, or bubbling of the exterior paint or clear coat. This ?Mars Red? paint is sometimes referred to as ?Fire Opal.? A motion for approval of the settlement was filed with the Court on December 21, 2020. The settlement must receive final approval from the court before it takes effect. As part of the settlement, MBUSA has agreed to offer sliding-scale warranty coverage for certain vehicles to repaint any non-plastic exterior surface of a Subject Vehicle because of peeling, flaking, or bubbling of the exterior paint or clear coat. This warranty coverage does not cover repainting necessitated by external influences such as automobile accidents, scratches, or road debris. Warranty coverage will not take effect until the settlement is judicially approved and other events occur. If the settlement becomes effective, coverage will include inspection of the vehicle to diagnose the possible cause of any observed peeling, flaking, or bubbling of the exterior paint or clear coat.
