If Model S is unable to detect the key, the
touchscreen displays a message indicating that a key is not inside. Place the key where
Model S can best detect it, which is below the
12V power socket (see Key Not Inside on page
43).
Radio equipment on a similar frequency can
affect the key. If this happens, move the key at
least one foot (30 cm) away from other electronic devices (phone, laptop, etc). If the
key does not work, you may need to change
its battery. If the key

8. Use the right steering wheel buttons to change what displays on the right side of theinstrument panel whenever a phone call is not active (see Using Right Steering Wheel Buttons
on page 40).
9. Total estimated driving distance (or energy) available. Instead of driving distance, you can display the percentage of battery energy remaining. To do so, touch Controls > Settings >Language & Units > Energy & Charging (see Settings on page 101).
Note: When anticipating when you need to charge, use range estimates as a general guideline only.
Note: In cold weather, some of the stored energy in the Battery may not be available on your drive because the Battery is too cold. When this happens, a portion of the Battery meter isblue and the driving distance value has a
snowflake image next to it. If Model S is plugged in,
you can heat your Battery using wall power by turning on climate control using the mobile app. When the Battery warms up, the blue portion on the meter and the
snowflake image are
no longer displayed.
10. The speed limit (if available) that is currently being detected by Speed Assist (see Speed
Assist on page 91).
11. The car in front of you (if applicable).
Note: In situations where Autosteer is unable to detect lane markings, the driving lane isdetermined based on the vehicle you are following. In these situations, the car in front of you
is highlighted in blue.
12. Pay attention to important driving-related messages that appear at the bottom center of the instrument panel.

Regenerative Braking
Whenever Model S is moving and your foot is
off the accelerator, regenerative braking slows
down Model S and feeds any surplus energy
back to the Battery.
By anticipating your stops and simply
removing pressure from the accelerator to slow down, you can take advantage ofregenerative braking to increase driving range.
Of course, this is no substitute for regular
braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model S, such as on a steep descent,
brake lights turn on to alert other road users
that you are slowing down.
The Energy app displays real-time feedback
on the amount of energy being gained by
regenerative braking. You can also display the
power meter on either side of the instrument
panel by choosing Energy using the scroll
button on the steering wheel (see Steering
Wheel on page 39).
The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. If regenerative
braking is limited, a dashed yellow line
displays on the power meter. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is low.
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative Braking .
2. Choose from two levels:

Overview of Climate Controls
The climate controls are always available at the bottom of the touchscreen. By default, climate control is set to Auto, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the temperature, the system automatically adjusts the heating, air
conditioning, air distribution, air circulation, and fan speed to maintain your selected temperature. To override these settings, touch Auto (see Customizing Climate Control on page 106).
The fan, heating, and air conditioning systems are powered by the Battery. Therefore, prolonged
use decreases driving range.
Note: The following illustration is provided for demonstration purposes only. Depending on vehicle
options, software version, market region, and settings, the information displayed may be slightly
different.
1. The front seats are equipped with heating pads that operate at three levels from 3 (highest) to
1 (lowest).
When operating, the indicator turns red and displays the setting number.
Note: If Model S is equipped with the optional cold weather package, you can also control seat heaters in the rear seats, heated wipers, and heated steering wheel by touching Controls > Cold Weather (see Controls on page 98). When equipped with the optional executive rear
seats, you can control the seat and the backrest separately in each second row passenger
seat.
2. Touch the up or down arrow to set the cabin temperature. To apply a temperature setting to both the driver and passenger side at the same time, touch SYNC TEMP on the temperaturepopup that appears when you touch an arrow.
3. Automatic/Manual climate control (see Customizing Climate Control on page 106).
4. The windshield defroster distributes air
flow to the windshield. Touch once to turn on, touch a
second time to operate the heating and fan at their maximum level, and touch a third time to
turn
off and restore the air distribution, heating, and fan to their previous settings.
5. Turn climate control system on/off.6. The rear window defroster warms up the rear window for 15 minutes, then automatically shutsoff. Exterior side mirrors are also heated.
Note: Depending on date of manufacture and options selected at time of purchase, some vehicles are not equipped with a heaters in the exterior side mirrors.
Warning: To avoid burns resulting from prolonged use, individuals who have peripheral neuropathy, or whose capacity to feel pain is limited because of diabetes, age, neurologicalinjury, or some other condition, should exercise caution when using the climate control
system and seat heaters.

If you select Always Show Estimated Round
Trip Energy in the Navigation settings, Model S also lets you know if you have enough
energy for a round trip at the bottom of the
turn-by-turn directions. By default, an estimate of your round trip energy usagedisplays at the bottom of the turn-by-turn
directions when the remaining battery energy
is estimated at less than ten percent after
completion of the round trip, or when the round trip consumes a
significant amount of
your energy.
When navigating, you can also use the Energy
app to monitor energy usage while on your trip (see Getting Maximum Range on page
65).
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 that minimizes the time you spend driving andcharging. To use Trip Planner, touch Controls
> Settings > Apps > Maps and Navigation >
Trip Planner > On .
After you select a destination, Trip Planner
zooms out to give you an overview of your
trip. As you begin your trip, Trip Planner zooms in to start navigation. The turn-by-turn
directions include:

About the Security System
If Model S does not detect a key nearby and a
locked door or trunk is opened, an alarm sounds and headlights and turn signals
flash.To deactivate the alarm, press any button on the key.
To manually enable or disable the alarm
system, touch Controls > Settings > Safety &
Security > Alarm . When set to on, Model S
activates its alarm one minute after the doors
lock and a recognized key is no longer
detected nearby.
If Model S is equipped with the optional
security package, it includes a battery-backed
siren that sounds instead of the horn in situations where a locked door or trunk isopened and Model S does not detect a key
nearby. If the Tilt/Intrusion setting is on, the siren also sounds if Model S detects motioninside the cabin, a window is broken, or if it is
moved or tilted (for example, with a tow truck
or jack). To turn the tilt/ intrusion detection systems on or
off, touch Controls > Settings
> Safety & Security > Tilt/Intrusion .
Note: If you plan to leave something that
moves, such as a dog, inside your locked
Model S, remember to turn
off the tilt/
intrusion system. Any type of motion detected
inside Model S activates the siren.
Note: To turn on Tilt/Intrusion, the Alarm must
be ON.

About the Battery
Model S has one of the most sophisticated
battery systems in the world. The most
important way to preserve the Battery is to LEAVE YOUR Model S PLUGGED IN when you
are not using it. This is particularly important if you are not planning to drive Model S for
several weeks. When plugged in, Model S wakes up when needed to automatically
maintain a charge level that maximizes the
lifetime of the Battery.
There is no advantage to waiting until the
