System Initialization
If for any reason, you lose power to
the compass system (the battery was
disconnected), the system needs to
be initialized before you can use it.
Initialization requires this:
Entry of the compass system 4-
digit security code to ''unlock'' the
system.
GPS initialization. This may not be
needed depending on how long the
system was without power.
Compass System (U.S. model without navigation system)
Entering the Security Code
If the battery goes dead or is
disconnected for any reason, you will
have to enter a security code into
both the audio system and the
compass system before you can use
it again.
When you purchased the vehicle,
you should have received two cards
that have the audio and compass
system's security codes and serial
numbers. Keep these cards in a safe
place in case you need the codes. If
you lose the cards, you must obtain
the security codes from your dealer.
Enter the four-digit compass system
security code. If you have entered it
correctly, the display changes to the
Disclaimer screen . You have ten
chances to enter the correct code. If
all ten are incorrect, turn the ignition
to OFF, then back to ON (II) to have
ten more chances to enter the
correct code.
To enter the code, turn the interface
knob to select the number, then
press the interface selector to enter
it. Keep doing the same procedure to
enter all four correct numbers. If you
need to delete the number you
entered mistakenly, move the
interface selector to the right.
