4.1 Concepts 
4.1.1 Smart Zoom 
Smart Zoom provides much more than just a usual automatic zoom feature: \
• While following a route:  when approaching a turn, it will zoom in and raise the 
view angle to let you easily recognize your maneuver at the next junctio\
n. If the 
next turn is at a distance, it will zoom out and lower the view angle to\
 be  fl at so 
you can see the road in front of you. 
•  While driving without an active route:  Smart Zoom will zoom in if you drive 
slowly and zoom out when you drive at high speed. 
•  Off: Turns the Smart Zoom setting off.
4.1.2  Route calculation and recalculation 
The navigation system calculates the route based on your preferences:
•  Route planning methods:  • 
 : Gives a quick route if you can travel at or near the speed limit 
on all roads.
• 
 : Gives a route that has the smallest total distance of all possible 
routes. 
• 
 : This method combines the merits of the Fast and Short 
routes: The navigation system makes a calculation for the Fast route, 
but it also includes other roads in the calculation in consideration of \
fuel 
economy.
• 
 : Results in a route with fewer turns and no dif fi cult maneuvers. 
With this option, you can make the navigation system take, for example, 
the highway/freeway instead of a series of smaller roads or streets.
