Getting Started
Before you begin to operate the navigation system, read
this manual thoroughly to become familiar with it and
to understand how the system works.
The navigation system allows you to do the following:
Plan a route with provided turn-by-turn route
and map guidance with voice prompts.
Select a destination using various methods
and choices.
The information in the system may not always be
complete. Road conditions such as prohibited turns,
detours, and construction zones, change frequently.
It is important to consider whether you can follow
the directions given by the system for the current
conditions.
When getting started, you may set the navigation system
to your preference using various options. You will also

Navigation Audio System
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See
“Retained Accessory Power (RAP)” in Section 2 of
your vehicle’s owner manual for more information.
The audio system is operated using navigation system
menus. The audio menus are explained in this section.
