Complaint After a software update of HERMES communication module N112/9 has been performed on a gray import vehicle, the message "SOS - Service not activated" is displayed in the instrument cluster. Cause The message "SOS - Service not activated" tells the customer that "over-the-air" registration of the vehicle with the Mercedes Intelligent Cloud is not possible. On a gray import vehicle, this is due to the fact that the SIM card installed in the HERMES communications module cannot dial into the mobile phone network in the importing country. Remedy The only way of avoiding the message in the instrument cluster is to deactivate the HERMES module using the 09o deactivation process after obtaining the customer's consent. After deactivation, the HERMES control unit (N112/9) has the operating status "Inoperative". The message "SOS not ready" appears in the audio/COMAND display (A40/8) and may also appear in the instrument cluster. This display message tells the customer that the emergency call function is not available. In addition, the workshop must attach a label (2 x part number A9078172900 required) to the cover of the emergency call button in the overhead control panel and to the emergency call button itself. Replacing the hardware of the HERMES communication module is not effective.

Complaint Headlamps leaking or fogged Cause The fogging of the headlamp is a natural phenomenon which can occur under certain climatic conditions. In contrast to a leaky headlamp, physical fogging does not result in a technical impairment of the headlamp. A leak test must be performed to determine if physical fogging exists or if the headlamp is leaky. Remedy Check for external damage: You can identify a damaged headlamp in the following way: For headlamps with a closed system 1. Check the headlamps for any external damage and check also for correct seating of the Gore-diaphragm/correct latching of the cover caps. 2. If the headlamp exhibits any external damage, replace the headlamp. For headlamps with an open system 1. Check the headlamps for any external damage and seal off the vent, then make sure the cover caps are latched correctly into place. 2. If the headlamp exhibits any external damage, replace the headlamp. Note: External damage to the headlamp does not present a warranty or goodwill case. 1. Clear fogged/condensed LED headlamps and LED rear lamps: 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 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). 7. If the condensation has disappeared, nothing else has to be done. Note: If defrosting has been performed, you can skip the first step. 2. Leak test of headlamp with overpressure: • Connect test adapter to pressure tester. (Figure 1) • Check test adapter for leak tightness. To do so, connect plug and coupling (picture 2) and apply a maximum overpressure of 30 mbar. The pressure must remain constant. If the pressure does not remain constant, use a new adapter. • All vents have to be sealed with sealing compound and the existing diaphragm with the stamp (picture 3 [3]). (Picture 4) Make allowance for the different headlamp variants here (there are different outlet openings). • Check if the headlamp needs to be removed to gain access to the diagnostic socket on the headlamp housing. • Plug the adapter onto the diagnostic socket on the headlamp housing. (Picture 5). • Apply a maximum of 30 mbar overpressure to the headlamp housing. Note: If the maximum overpressure of 50 mbar is exceeded the headlamp seal will be damaged (picture 6). • If a pressure drop of less than 10 mbar is measured within 30 seconds, the headlamp is tight and there is natural physical condensation. • If a higher pressure drop than 10 mbar is measured within 30 seconds, the headlamp is leaky. Note: The leaky position can be localized with the aid of soap suds. If the pressure test is not passed, the headlamp is leaky. If the cause cannot be rectified, the headlamp must be replaced. Note: If the headlamp is replaced, no dry packs may be installed on the new replacement headlamp. AR82.10-P-5455WT was created for the pressure test. This AR can be used as a reference manual for all closed headlamps. In the event of an open headlamp system, the vent ducts must be sealed before the pressure test.

Complaint Headlamp, 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. Remedy NOTE: If a pressure compensation diaphragm is fitted in the housing cover, then the lamp unit is a "closed system". 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 damage. (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-078896 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.

Complaint Tailgate opens unintentionally. Cause Accidental or unnoticed activation of the button to open the tailgate on the vehicle key. E.g. when stored in trouser pocket, handbag etc. Remedy As of the 6th generation, the vehicle key can be recoded so that the tailgate no longer opens as a result of a long press on the button, but by double-clicking on the button instead. This reduces the likelihood of the button being activated accidentally or unintentionally. The recoding can be carried out as follows: 1. Enter AO Code O19 into VeDoc (O for Oscar, not "zero") 2. EZS N73: Perform SCN coding 3. Deactivate the vehicle key (a successful deactivation is indicated by the LED lighting up 2x briefly and then 1x for a long period). 4. Place the vehicle key on the key symbol in the storage compartment and then switch on the ignition. All other vehicle keys must be outside of the vehicle when doing this! Perform steps 3 and 4 successively for all vehicle keys. Notes: 6th, 7th and 8th generation keys can be deactivated as follows: Up to modification year 22/1 double-click on the locking button As of modification year 22/1, by pressing and holding the locking button + double-clicking on the release tab On model series 167, the storage compartment with the key symbol is located in the armrest. The SCN coding from the EZS is only transferred correctly to the vehicle key under the following conditions: Only one vehicle key is located in the vehicle, this key has been deactivated and it is positioned on the marking in the storage compartment for the data transfer. The costs for this adaptation are to be borne by the customer.

Complaint The flap of the reversing camera opens and closes by itself during forward travel several times during the trip. No camera image is displayed in the head unit. The reversing camera or the 360° system functions normally when activated manually or by engaging drive range "R". Cause This is not a malfunction, but an intended system behavior. Calibration of the reversing camera is in progress. The calibration is completed by: • Opening the camera cover for a maximum of 5 cumulative minutes. • If the vehicle speed is < 35 km/h (<22 MPH). • The steering wheel angle is < 10°. If calibration is aborted by exceeding one of the above conditions, the camera retracts and the calibration will re-attempt once the conditions are achieved and the speed returns to the range of 18 km/h (~11 MPH). Remedy SCN code PARK213M on MFA2 facelift vehicles produced after 09/2024 (A-Class, CLA, GLA, etc...) so the complete calibration speed window is available. For vehicles with PARK213M or PARK223 a calibration is completed successfully by: • Driving forward (typically less than 1 minute). • Vehicle speed is < 35 km/h (<22 MPH). • The steering wheel angle is < 10°. • During daylight. • Without a vehicle following too closely (camera must be able to see asphalt). When calibration has completed successfully, the camera door closes automatically for the rest of the driving cycle. The camera will now only open if the customer requests (Example: Engaging reverse gear). The calibration of the camera will re-initiate every drive cycle (ignition change). The customer can generally perform calibration at the first attempt while briefly maintaining a speed range of 15 km/ h (~9 MPH) and 35 km/h (~22 MPH). The customer can therefore play a significant role in reducing the camera door noise and actuation frequency.

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 and driving styles. Please refer to the Operator's Manual for further information such as care and maintenance instructions (washing vehicle directly after heavy use and using approved cleaning agents). These are dependent on speed, brake pressure or ambient conditions such as temperature and air humidity. 1. Beginning Diagnostics: a) Check whether, apart from this document, an additional document exists for the model series in question, and if so, work through it and then continue with1b. b) Check whether the complaint can be reproduced and at which axle or side the noises occur (ideally together with the customer while driving). c) Check the affected system for component wear, mechanical damage or localized overheating damage. 1. Replace damaged components as necessary and re-assess noise concern. d) Secure vehicle on a lift. 1. Start the engine and depress the brake pedal 3-4 times. 2. Check each wheel to see if they turn freely by hand. 3. If a wheel is not turning freely by hand, this needs to be addressed prior to re-assessing the noise concern. e) Assess condition of brake rotors and pads per WIS and visually (i.e. long periods of stagnation, etc...). 2. Specific Axle Work: NOTE: If brake pad has a metal backing plate, there is no need to affix the adhesive film. a) If the noises are coming from the front axle => Affix linings with adhesive film (see attachments for front axle). If backing plate is installed on pads, move to step 3. 1. Remove brake linings of front axle. 2. Clean all contact points on brake lining and brake caliper/carrier. 3. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining. For 6 piston calipers, only in the area of the center piston. For other piston caliper configurations less than 6, apply where the piston(s) makes contact with the back of the pad. 4. Chamfer edges (round off sharp leading edges) on brake pads. See picture "Chamfered Pads". 5. After installing the brake linings, actuate the brake for 30 seconds. b) If the noises are coming from the rear axle => Affix linings with adhesive film and grease the lining as per the specification (see attachments for rear axle). 1. Remove brake pads of rear axle. 2. Cleaning all contact points on brake lining and brake caliper/carrier. 3. Grease contact points (red areas) between brake lining and guide of brake caliper with heat-resistant lubricating paste. 4. Clean bonding surface (where pistons contact back of brake pad). Apply adhesive film to the backplate of the piston-side brake lining. 5. Chamfer edges (round off sharp leading edges) on brake pads. See picture "Chamfered Pads". IMPORTANT: Be absolutely certain to not allow paste between friction surfaces of the pad and disc! 3. Brake Bedding Process: a) Before trip, the mileage incurred must be clarified with the customer (approx. 30 miles). b) Select a suitable route so speeds of approximately 65 MPH can be achieved. c) Brake the vehicle 15 times with a brake pressure of approx. 30 bar (have the passenger read it out using XENTRY) from 62 MPH to 30 MPH (no emergency stops and no braking in the ESP control range). Maintain a cooling distance of approx. 1 mile between brake applications. d) Finally drive approx. 3 miles to allow the system to cool. e) Reassess noise.
