RELATED TO HANDS-FREE PHONE

• Before performing diagnosis, confirm that the cellular phone being used by the customer is compatible with

the vehicle.

• It is possible that a malfunction is occurring due to a version change of the phone even though the phone is

a compatible type. This can be confirmed by changing the cellular phone to another compatible type, and

check that it operates normally. It is important to determine whether the cause of the malfunction is the vehi-

cle or the cellular phone.

Check Compatibility

1. Make sure the customer’s Bluetooth

related concern is understood.

2. Verify the customer’s concern.

NOTE:

The customer’s phone may be required, depending upon their concern.

3. Write down the customer’s phone brand, model and service provider.

NOTE:

It is necessary to know the service provider. On occasion, a given phone may be on the approved list with

one provider, but may not be on the approved list with other providers.

4. Go to “www.nissanusa.com/bluetooth/”.
a. Using the website’s search engine, find out if the customer’s phone is on the approved list.
b. If the customer’s phone is NOT on the approved list:

Stop diagnosis here. The customer needs to obtain a Bluetooth

phone that is on the approved list before

any further action.

c. If the feature related to the customer’s concern shows as “N” (not compatible):

Stop diagnosis here. If the customer still wants the feature to function, they will need to get an approved

phone showing the feature as “Y” (compatible) in the “Basic Features”.

d. If the feature related to the customer’s concern shows as “Y” (compatible):
