PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL

NOTE:

When disconnecting the cable from the negative (-) battery terminal, initialize the following system after the cable is reconnected.

System Name	See Procedure
Parking Assist Monitor System	Refer to INITIALIZATION [08/2013 - ]

NOTE:

After the engine switch is turned off, the navigation system requires approximately 60 seconds to record various types of memory and settings. As a result, after turning the engine switch off, wait 60 seconds or more before disconnecting the cable from the negative (-) battery terminal.

If the cable has been disconnected from the negative (-) battery terminal before 60 seconds has elapsed, it is necessary to initialize the system. To initialize the system, perform the following procedures:
1. Move the vehicle to an open area with good GPS reception.
  HINT:
  
  The GPS icon is displayed on the map screen when the reception is good.
2. Turn the engine switch on (IG), and then wait several minutes while the system acquires time and location data and activates Destination Assist and Destination.
3. Turn the engine switch off and then on (IG) again to initialize XM Sports and XM Stocks services.
  HINT:
  - XM Sports and XM Stocks services are only available if XM Radio is active and the vehicle is equipped with LEXUS ENFORM.
  - XM Sports and XM Stocks services may take several minutes to update.

PRECAUTIONS FOR MULTI-MEDIA MODULE RECEIVER ASSEMBLY

A Hard Disk Drive (HDD) is built into the multi-media module receiver assembly to store map and other data, and is used for the navigation system. Therefore, care must be taken for the following points when handling:

Hard Disk Drive

When it is necessary to replace the multi-media module receiver assembly, be sure to replace it with a new one.
NOTE:
If a used multi-media module receiver assembly is installed as a replacement part, the customer's HDD will not be recognized.
Do not apply any vibration or shock to the multi-media module receiver assembly.
NOTE:
- Do not drop or subject the multi-media module receiver assembly to severe impacts.
- Do not use the multi-media module receiver assembly if it has been dropped or subjected to a severe impact.
- Do not store the multi-media module receiver assembly without the HDD installed. (Only remove the HDD from the multi-media module receiver assembly when the replacement multi-media module receiver assembly or HDD is ready.)
Do not remove the multi-media module receiver assembly if there is a risk that condensation may occur.
NOTE:
If the temperature of the multi-media module receiver assembly changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the multi-media module receiver assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.
Take measures to prevent static electricity.
NOTE:
Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.
Keep the multi-media module receiver assembly away from magnets or magnetized items.
NOTE:
Keep the multi-media module receiver assembly away from speakers, motors, magnetized tools and other magnetic items.

PRECAUTIONS FOR HARD DISK DRIVE (HDD)

Map and other data for the navigation system is stored on the Hard Disk Drive (HDD). Make sure to follow the following instructions when replacing the HDD:

NOTE:

Data downloaded by the customer may be stored on the HDD. This data will be lost when the HDD is replaced. Make sure to warn the customer that their data will be lost and obtain their consent prior to replacing the HDD.

The HDD must only be replaced with a new one. Do not attempt to install a used HDD from another vehicle.
NOTE:
The multi-media module receiver assembly can recognize only a new HDD.

Do not touch the HDD cover.

Fig 2: Identifying Correct/Incorrect Way To Hold HDD

NOTE:

When removing or installing the HDD, only hold it by the areas shown in the illustration.

*a	Example
*b	Correct
*c	Incorrect

Do not apply any vibration or shock to the HDD.
NOTE:
- Do not drop or subject the HDD to severe impacts.
- Do not use the HDD if it has been dropped or subjected to a severe impact.
- Do not store the HDD by itself if it has been removed from the multi-media module receiver assembly. (Only remove the HDD from the multi-media module receiver assembly when the replacement multi-media module receiver assembly or HDD is ready.)
Do not remove the HDD if there is a risk that condensation may occur.
NOTE:
If the temperature of the HDD changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the multi-media module receiver assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.
Take measures to prevent static electricity.
NOTE:
Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.
Keep the HDD away from magnets or magnetized items.
NOTE:
Keep the HDD away from speakers, motors, magnetized tools and other magnetic items.
Inspect after HDD replacement.
NOTE:
Make sure to perform Check Hard Disk Drive in Operation Check to confirm that there are no HDD abnormalities after removal or installation. Refer to OPERATION CHECK [08/2013 - ] .
