2. To calibrate, press and hold the 7
and 9 radio preset buttons together
for approximately 10 seconds until
CAL appears. Release the buttons.

may take up to five circles to
complete calibration.

AUXILIARY POWER POINT (12VDC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
The auxiliary power point is located
on the instrument panel.
Do not use the power point for
operating the cigarette lighter
element (if equipped).
To prevent the fuse from being
blown, do not use the power
point(s) over the vehicle capacity of
12 VDC/180W. If the power point or
cigar lighter socket is not working, a
fuse may have blown. Refer to Fuses and relays in the Roadside
Emergencies chapter for information on checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
• do not use the power point longer than necessary when the engine is
not running,
• do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.
