Wheel Alignment Data
In order to ensure the accuracy of our MKS alignment process, all ride height data must be transferred to the MKS alignment console via the
required Romess docking station. Effective repair date February 1, 2013, any wheel alignments performed with manually entered ride height data
may be subject to debit.

NOTE:
As in Figure 1, an "ed" after the vehicle axle level indicates data has been entered manually, which is not acceptable.

Parktronic Malfunctions and Faults
This is an overview of Parktronic malfunction and fault scenarios, respectively.
Malfunction Scenario 1
Malfunctions are indicated with double red (4 LEDs) warning elements and no warning tone (Figure 1).
An entry is not saved in fault memory.
Malfunctions can be triggered by external ultrasonic signals:
^ Compressed air
^ Drier blower for a washer system
^ Rail vehicles
^ Brake squeal on vehicle or a nearby vehicle
Or through:
^ Soiling of sensors with ice or snow
^ License plate brackets
Fault Scenario 2
Faults are indicated in the Parktronic warning elements with double red (4 LEDs) with warning tone (Figure 1) (see arrows).
An entry is saved in fault memory.
The sensor function is automatically checked while driving at between 22-37 mph. If a fault occurs when driving, then this is issued at a speed less
than 9 mph with double red lights and warning tone.
The following applies to both scenarios:
If a malfunction or a fault is present for more than 2 seconds, the display in the warning elements goes out and the PARKTRONIC OFF button in the
UCP lights up in red.
Diagnosis
  77
To fix issues that cannot be clearly located via fault codes in fault memory, check for correct and central installation (Figure 3) (C) or for any
damage caused by stone chipping (Figure 2) (A) (B).
The decoupling ring must be centered and custom fit when installed (Figure 3) (C) and Figure 4 (C). Refer also to S-B-54.651251 Parktronic Sensor

Mercedes-Benz HVAC-Foam Cleaner - Work Procedure
NOTE:
This procedure is not approved for vehicles covered under warranty. Refer to LI83.00-P-051588 for details on which vehicles can be cleaned under
warranty using Mercedes-Benz Contra Sept disinfectant cleaner (S-B-83.30/134). Additionally, the combination filter is a maintenance item and is
not covered under warranty.
Procedure
1. Start the engine with the A/C ON, temperature set to coldest setting, inlet set for outside air (not recirculate) and blower set for high speed.
Note:
The A/C must be run for at least 15 minutes to get condensation to build on the evaporator. This will adequately wet evaporator and promote the
product's ability to clean.
2. Locate the evaporator core case and blower assembly by removing any covers below the instrument panel on the passenger's side that may cover
the case.
3. Remove the cabin air filter and close off the empty filter cavity with the filter block off plate
^ For models where the filter bock off plate is integrated with the filter media (as with model 204/212). Remove the filter media, leaving the
bare block off plate, which can be reinstalled for the cleaning procedure (Figure 1).
4. On vehicles with an activated charcoal filter, remove these filters as well.
5. Drill a 3/16" hole in an accessible location between the evaporator core case & blower assembly, depending on your vehicle model. Use a drill
stop set at the thickness of the case to prevent plunging into case too deep.
Warning!
Follow the diagrams for a given vehicle model series, otherwise damage to the evaporator may occur.
^ Only drill through the case skin and gently probe inside with a dull instrument for any obstructions that the nozzle may encounter. If needed, use
the supplied plug and find another spot to drill.
  75
6. Shake the disinfectant product can and with the hose attached to the can push the nozzle into position & rotate so the pointer faces the evaporator
core (Figure 2).
7. With the blower still on, start dispensing the foam in short bursts. As the case fills with foam, airflow will decrease from the vents. Pause for the
blower to push the foam through the core. (If the fan starts to squeak, stop dispensing while the blower catches up). As airflow resumes, continue
with short bursts of foam. If the system is overloaded by dispensing the foam too quickly, foam can escape from components under the dashboard.
NOTE:
Do not allow the foam to drip to any electronic components. Intercept any escaping foam with a towel.
To prevent possible staining, do not allow any foam to blow out of vents onto seating or other interior materials.
8. Continue with this application method until the can is empty then shut the system off completely.
9. After a minimum 10-minute wait, turn the blower on LOW to MEDIUM for 2 minutes to push excess foam out of the core.
10. Check that the drain is flowing freely under the vehicle. If there is no drainage, the drain is clogged. A clogged drain must be cleared.
Condensation will rinse out any remaining cleaner residue and contaminants.
11. Reinstall new cabin filters and activated charcoal (if equipped).
NOTE:
It is required that you replace the cabin filter after treatment. It is recommended that you replace the activated charcoal filters (if equipped).
Additional instructions for this procedure will be available via Learning & Performance:
VILT Course Code:X0001F-US.TTA (starting in second quarter 2012).

A/C Sealant
If refrigerant circuit becomes leaky while under warranty, do not apply sealant. This can lead to contamination of the air conditioning service unit
and damage the vehicles refrigerant circuit.
The damaged part must always be determined using the usual inspection procedures and replaced by a genuine Mercedes-Benz new part.
Returned components that have been contaminated, damaged or clogged by sealant will not be covered under warranty.
  37
NOTE:
If sealant is in the refrigerant circuit of the air conditioning system, this cannot be determined before the refrigerant is extracted. To determine if
sealant has been used in previous repairs, look for an adhesive label affixed to the engine compartment of the vehicle Protective devices for air
conditioning service units are offered by some manufacturers. They must be requested from the manufacturer of the air conditioning service unit.

Order No.: S-B-80.61/59
Group: 80
SUBJECT:
All Model Vehicles with Keys Having One Battery
Instrument Cluster Message "Replace Key Battery" Appearing Soon After New Key Battery Replacement
Customer Complaint: The message "Replace Key Battery" is displayed in the instrument cluster not long after the key battery was last replaced
Condition/Background: If the battery was recently replaced and the customer has this message in the Instrument Cluster, Product Technical
Support is interested in gathering more data to determine the root cause of this issue.
Action: Please open and close a PTSS case and include as much of the following information that is possible to obtain:
VIN - Vehicle's VIN
Key Date Code - Date code of the key that is experiencing the issue (last 4 digits on barrel)
1st Batt Repl - The last time the customer came in to get a new battery in their key
2nd Batt Rep - The date that the customer came in with the low battery message in the instrument cluster, requiring another battery replacement
Brand - The brand of the battery (Duracel, Panasonic, etc.)
Source - Where the battery came from (e.g. the PDC, local Walmart, etc.)
Tensioned - The last time the customer came in, were the key battery contacts tensioned?
Enhanced - The last time the customer came in, were the key battery contacts cleaned/enhanced?
Driving Frequency - How many times a day, on average, does the customer get in and out of their vehicle? Do they get in and out 20 times, 2 times,
8 times?
Ride length - What is the average drive length per drive cycle? This is important because the KG system pings the keys every 5km for 20km - for a
total of 5 times per drive cycle max.
Driving habits - Where does the customer keep their key when driving?
Parking Habits - Where does the customer park their car? Do they lock it? Do they keep the key in the vehicle overnight?

When creating the case, please use the symptom string >Overall vehicle>Safety and locking system>Locks/locking/Remote closing
mechanism>Discharged battery. Finally, replace the key battery with a new battery by lightly and carefully tension the contacts, cleaning the contacts
using contact cleaner, and using a clean cloth to insert the battery into the key.
