Electrical Components InspectionNJEL0051FUEL WARNING LAMP OPERATION CHECKNJEL0051S011. Turn ignition switch “OFF”.
2. Disconnect fuel level sensor unit harness connector B29.
3. Connect a resistor (80Ω) between fuel level sensor unit har-
ness connector terminals 4 and 1.
4. Turn ignition switch “ON”.
The fuel warning lamp should come on.
NOTE:
For QG Engine Only
ECM might store the DTC P0180 during this inspection. If the DTC
is stored in ECM memory, erase the DTC after reconnecting the
fuel level sensor unit and fuel pump harness connector. Refer to
EC-48 (With EURO-OBD), 430 (Without EURO-OBD), “HOW TO
ERASE EMISSION-RELATED DIAGNOSTIC INFORMATION”,
“Emission-related Diagnostic Information”, “ON BOARD DIAG-
NOSTIC SYSTEM DESCRIPTION”.

SPEED DEPENDENT VOLUME CONTROLNJEL0497S13DescriptionNJEL0497S1301If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises
at higher driving speeds.
The radio receives a speed signal from the combination meter and selects the output volume.
PERSONAL AUDIO SETTINGSNJEL0497S14DescriptionNJEL0497S1401The radio is designed to store several settings (volume, bass, treble, preset stations and level of speed
dependent volume control) with every NATS ignition key used. Up to a maximum of 4 NATS keys can be reg-
istered. During the communication mentioned under “Anti-Theft System”,the radio will recognize the used
ignition key and select the accompanying settings.
