Maps and Navigation
Predicting Energy Usage
When navigating to a destination, Model S helps you
anticipate your charging needs by calculating the
amount of energy that remains when you reach your
destination. The calculation is an estimate based on
driving style (predicted speed, etc.) and environmental
factors (elevation changes, temperature, etc.). When
navigating, the map displays this calculation at the
bottom of the expanded turn-by-turn direction list (see
Navigating to a Destination on page
turn-by-turn direction list is compressed, touch the top
of the list to expand it.
Throughout your route, Model S monitors energy usage
and updates the calculation. A popup warning displays
at the bottom of the turn-by-turn direction list in these
situations:
• A yellow warning displays when you have very little
energy remaining to reach your destination, requiring
you to drive slowly to conserve energy. For tips on
conserving energy, see
page 68.
• A red warning displays when you must charge to
reach your destination.
To determine if you have enough energy for a round trip,
touch the battery icon at the bottom of the turn-by-turn
direction list to display an estimated calculation of your
round trip energy usage.
Online Routing
Model S detects real-time traffic conditions and
automatically adjusts the estimated driving and arrival
times. In situations where traffic conditions will delay
your estimated time of arrival and an alternate route is
available, the navigation system can reroute you to your
destination. You can also specify the minimum number
of minutes that must be saved before you are rerouted.
To turn this feature on or off, touch the map's settings
icon (see Navigation Settings on page
Online Routing.
Trip Planner
Trip Planner helps you take longer road trips with
confidence. If reaching your destination requires
charging, Trip Planner routes you through the
appropriate Supercharger locations. Trip Planner selects
a route and provides charging times to minimize the
amount of time you spend driving and charging. To
enable Trip Planner, touch the map's settings icon (see
Navigation Settings on page
Planner.

When Trip Planner is enabled and charging is required to
reach your destination, the turn-by-turn direction list
includes Supercharger stops, recommended charging
times at each Supercharger, and an estimate of how
much energy will be available when you arrive at the
Supercharger location.
NOTE: When navigating to a Supercharger or, in some
regions, a third-party fast charger using Trip Planner,
Model S may allocate some energy to pre-heat the
Battery to arrive at the Supercharger or third-party fast
charger with an optimal Battery temperature. This
reduces charging time (see
Supercharging on page 73).
To remove Supercharger stops and display directions
only, touch Remove all charging stops at the bottom of
the turn-by-turn direction list. If you remove charging
stops, the turn-by-turn direction list may display an alert
indicating that charging is needed to reach your
destination. To add Supercharger stops back to the turn-
by-turn direction list, touch Add charging stops.
While charging at a Supercharger, the charging screen
displays the remaining charging time needed to drive to
your next Supercharger stop, or destination (if no
further charging is needed). If you charge for a shorter
or longer length of time, charging time at subsequent
Supercharger stops is adjusted accordingly.
NOTE: You can also use the mobile app to monitor
remaining charging time needed.
NOTE: If a Supercharger on your navigation route
experiences an outage, Trip Planner displays a
notification and attempts to reroute you to a different
Supercharger location.
If Trip Planner estimates that you won't have enough
energy for your round trip, and there are no
Superchargers available on your route, Trip Planner
displays an alert at the top of the turn-by-turn direction
list notifying you that charging is needed to reach your
destination.
Map Updates
As updated maps become available, they are
automatically sent to Model S over Wi-Fi. To ensure you
receive them, periodically connect Model S to a Wi-Fi
network (see Connecting to Wi-Fi on page

new maps are installed.
