Map Adjustments

The system allows you to adjust the scale of view on the map. Also, as you drive, the map will scroll automatically based on the direction of travel.

Map Scales

/ (Zoom In/Zoom Out): Select the zoom in or out screen buttons or the scale on the bar to change the level of map detail. The scale will appear on the screen once the zoom in or zoom out screen buttons are selected. The system will adjust the map accordingly. The scale of a map can range from 1/32 mi. (50 m) to 256 mi. (400 km). To change between English or metric, see "Driver Information Center, DIC Controls and Displays" in the Index of your vehicle's owner manual.

Scrolling the Map


Object Number: 811648  Size: A1

Touch anywhere on the map screen and the scroll symbol will appear. Use this feature to scroll across the map.

Move your finger in any direction on the map screen and the map will continue to scroll in that direction until you remove your finger.

If scrolling while your vehicle is in PARK (P), the system will scroll initially at a slower rate. The scroll speed will increase if you continue touching the map screen.

If scrolling while your vehicle is in motion, there is one scroll speed and a limited distance to scroll. You have to keep touching the map screen to scroll for a longer distance.

If you have used the scroll feature to scroll the map and your vehicle icon becomes lost, press the NAV (Navigation) key to return to the current vehicle location on the map.

Use the scroll feature on the map to set a destination. See "From Map" under Destination for more information.

When scrolling on the map without a planned route, press the GO screen button to calculate the route from your current position to the destination mark.
