Introduction

WARNING

Using the navigation system while driving can take your attention away from the road, causing a crash in which you could be seriously injured or killed.

Follow all operating instructions and safety information in this manual.

While driving, do not look at the screen or operate the system controls for more than a second or so at a time, and only after deciding you can do so safely. Pull to the side of the road if you need more time to look at the screen or operate the controls.

The navigation system is designed to provide route information to help you reach your destination. However, this route guidance may sometimes conflict with current road conditions such as street closures, road construction, detours, and out-of-date map data.

Additionally, the system itself has certain limitations (see page 99).

Therefore, you must verify the audio and visual route information provided by the system by carefully observing the roadway, signs and signals, etc. If you are unsure, proceed with caution.

Always use your own good judgment, and obey traffic laws while driving.

Map Overview

Current Street

The current street on which your vehicle is located appears at the bottom of the map screen (see page 18). A message saying “ Not on a digitized road” may appear instead when you drive half a mile away from a mapped road. For more details, see Off-road Tracking on page 60.

Verified/Unverified Street

Your navigation system has two kinds of streets: verified (dark colored) and unverified (light colored). The differences between the two types of streets are contrasted in the chart on page 7.

Verified streets (dark colored)

These roads are found within metropolitan areas, and include interstate freeways and major roads connecting cities.

Shown on daytime map screen as black or red, such as interstate freeways.

The database vendor has verified these streets.

Information like turn restrictions, average speed, and whether it is a one-way street have been gathered and used when creating your route to a destination.

While driving to your destination, the displayed route line is solid blue. The system provides voice and map guidance to your destination.

There are no pop-up boxes urging extra caution during a route. However, because roads constantly change, you are urged to use common sense, and always obey posted traffic restrictions.

Voice guidance issues instructions such as “In a halfmile, make a right turn.”

The time and distance “to go,” displayed while en route to a destination, is based on the average speed and distance for the roads used for your route.

Unverified streets (light colored)

These roads are found in rural areas, and typically include residential streets away from the center of a town.

Shown on the daytime map screen as light brown.

These streets have not been verified by the database vendor. The system does not contain information on one-way streets, turn restrictions, or the road’s average speed. They are shown on the map for reference and may have errors in map location, naming, and address range.

Your route line is either a blue dotted “vector line,” or a dashed pink/blue line. For information on selecting this option, and the routing differences, see Unverified Area Routing on page 83.

Regardless of whether the user chooses route guidance, there are cautionary screens before and during the route urging the user to be extra cautious, and obey all traffic restrictions. See Unverified

Area Routing on page 83.

The phrase “if possible” is added to each guidance instruction.

For example: “In a half-mile, make a right turn, if possible.”

Because the average speed of these roads is not known, the time and distance “to go” is based on a fixed average speed of 25 mph for these roads.
