CAUTION / NOTICE / HINT

NOTICE:
·

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed.

Click hereAudio / Visual / Telematics>NAVIGATION / MULTI INFO DISPLAY>NAVIGATION SYSTEM (w/o RST Switch (except 10.25 Inch Display))>PRECAUTION

·

Inspect the fuses and relays related to this system before inspecting the suspected areas below.

·

When replacing the combination meter assembly, make sure to replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in the combination meter assembly will not match the information from the vehicle and a DTC may be stored.

·

Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key, switches or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.

·

After turning the ignition switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.

When disconnecting the cable from the negative (-) auxiliary battery terminal, refer toAudio / Visual / Telematics>NAVIGATION / MULTI INFO DISPLAY>NAVIGATION SYSTEM (w/o RST Switch (except 10.25 Inch Display))>PRECAUTION

HINT:

When the cable is disconnected / reconnected to the auxiliary battery terminal, systems temporarily stop operating. However, each system has a function that completes learning the first time the system is used.

HINT:
·

Before disconnecting related connectors for inspection, push in on the connector body to check that each connector is not loose or disconnected.

·

When a connector is disconnected, check that the terminals and connector body are not cracked, deformed or corroded.
