  Summary

  In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz USA (“MBUSA”) is extending the coverage for the ignition coil on your vehicle from the original New Vehicle Limited Warranty of 4 years / 50,000 miles to 15 years / 150,000 miles (whichever occurs first),and applies to the vehicle regardless of ownership. Why the warranty extension? On certain Model Year vehicles, the ignition coil might not operate and meet specifications as intended, potentially illuminating the check engine Malfunction Indicator Lamp (‘MIL’). Any repairs under this warranty extension must be performed by an authorized Mercedes-Benz dealership. • If your preferred authorized Mercedes-Benz dealership performs a diagnosis and confirms that your vehicle has the issue, the repair will be performed at no cost to you. • This extended warranty does not apply to any other components or conditions beyond the ones mentioned above, and standard warranty terms apply, including the exclusions with respect to extra expenses, as identified in the Service and Warranty Information booklet.

  Summary

  In our continuing efforts to assure the proper performance of Mercedes-Benz products and to enhance the satisfaction of our customers, Mercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles is extending the warranty coverage on the ignition coil in certain Model Year ("MY") vehicles listed below from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 15 years/ 150,000 miles (whichever occurs first) due to the following condition: • The ignition coil might not operate and meet specifications as intended due to a fault in the winding process of the ignition coil. This may cause reduction in the coil's performance, and lead to combustion misfires on the affected cylinder. This may also cause an increase in exhaust emissions and result in the illumination of the check engine Malfunction Indicator Lamp ('MIL'). Please be advised that all repairs being claimed under this extended warranty must have a quick test uploaded with the following fault code information and may be audited. • P030022 - random/multiple cylinder misfire detected. • P030x85 or P030x00 - cylinder x misfire detected. (x = the affected cylinder)

  Summary

  Complaint The result from the XENTRY battery test does not match the current state of the battery. Cause The XENTRY battery tester uses the stored on-board electrical system data in the SAM module to access the health of the 12 volt battery. The XENTRY battery test may not take into account a single discharge event because the SAM cannot record the data if the battery is discharged. Note: A discharged battery does not necessarily need to be replaced. A discharged battery may be recovered with no permanent damage. Remedy Follow guided tests as described.

  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. If the initialization attempt is unsuccessful, repeat the initialization process, changing the distance between the hand transmitter and the mirror.

  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

  Complaint Insufficient cooling capacity and/or noises from refrigerant compressor Cause Under analysis Remedy In order to detect the fault, please perform the following test steps: 1. Connect manometer of air conditioning service unit in order to read off high pressure and low pressure 2. Connect XENTRY and bring up all climate control actual values in air conditioning menu under "actual values" 3. Set blower to speed 7 4. Set temperature on both sides (driver and front passenger) to LOW 5. Activate AC ON Result 1: Only a small pressure ratio is established (e.g high pressure 7-8 bar; low pressure 5-6 bar). Continue with step (A) Result 2: A larger pressure ratio is established (e.g high pressure 12-16 bar; low pressure 0-2 bar). Continue with step (B) (A): Check the dryer package for black oil and particles. (A.1) Black oil and particles present: Replace refrigerant compressor and valves, flush refrigerant circuit according to instructions in WIS (Refrigerant-only flushing method). Then put system into operation. If the high pressure and low pressure values are OK and the system functions as intended, the vehicle can be returned to the customer. If the pressure ratio is still not correct, continue with step (C) (A.2) No black oil or particles present: continue with step (B) (B): Disconnect vehicle-side power supply for shutoff valve Y19/3 and externally power shutoff valve Y19/3 with 12 V. With the blower setting still set to speed 7, allow the air conditioning system to run. Measure the low pressure while this occurs.
