2020 TESLA MODEL S battery

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
50).
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

Child-Protection Lock
Model S has child-protection locks on the rear
doors and liftgate to prevent them from being
opened using interior handles. Use the
touchscreen to turn child-protection locks on
or off. Touch Controls > Vehicle > Child-
Protection Lock .
Note: It is recommended that you turn child-
protection locks on whenever children are
seated in the rear seats.
Drive Away Locking
Model S automatically locks all doors
(including the trunks) whenever your driving
speed exceeds 5 mph (8 km/h).
Walk-Away Locking
Doors and trunks automatically lock whenever
you walk away carrying the key or if the key is
otherwise not detected by your vehicle (not
present, dead battery, etc.).
To turn this feature on or off, touch Controls >
Vehicle > Walk-Away Door Lock .
Note: Depending on date of manufacture and
options selected at time of purchase, some Model S vehicles are not equipped with the
Walk-Away Locking.
Note: If Model S detects an authenticated key
for five minutes after you exit the vehicle and
close all doors, Walk-Away Lock disables and will not lock when you leave with the key. You
will need to manually lock your vehicle until after your next drive.
Note: If all doors are closed and you use the
key to unlock Model S, walk away locking is temporarily suspended for one minute. If you
open a door within this minute, it does not re-
lock until after all the doors are closed and
you have walked away with the key.
Note: If your vehicle was unlocked using the
mobile app, it automatically locks after a short
period of time with all doors closed. If parking
in an area without cellular service, such as an
indoor parking garage, ensure that you have a
functional key fob readily available.Unlocking When the Key Doesn

12V Power SocketYour Model S has a power socket located onthe front of the center console. Power is
available whenever the instrument panel and
touchscreen are on.
The 12V power socket is suitable for
accessories requiring up to 11A continuous
draw (15A peak) or a maximum of 150
continuous watts (180 watts peak).
Note: Power is available whenever the vehicle
is considered "awake" The vehicle may be awake for many reasons. For example, when
using features such as Summon, or when features such as Smart Preconditioning, Cabin
Overheat Protection, Keep Climate On, Dog Mode, Sentry Mode, etc. are enabled. The
vehicle is also awake whenever the 12V battery
is being charged or is in use, during HV
charging, when the vehicle is communicating
with the mobile app, etc. Leaving an accessory
plugged in does not deplete the 12V battery.
Note: In situations where Model S is unable to
detect the key (low battery, interference, etc.),
place it immediately below the 12V power
socket where Model S can best detect it.

Starting and Powering
Off
Starting When you open a door, Model S powers on
the instrument panel and touchscreen and you
can operate all controls.
To drive Model S:
1. PRESS THE BRAKE PEDAL - Model S
powers on and is ready to drive.
2. SELECT A GEAR - Move the gear lever all
the way down for Drive and all the way up
for Reverse. See Shifting Gears on page
52.
Note: If the PIN to Drive feature is enabled
(see PIN to Drive on page 149), you must also
enter a valid PIN on the touchscreen before
you can drive Model S.
Note: If Passive Entry is off and you do not
press the brake pedal to start Model S within
approximately five minutes, a message
displays on the instrument panel and you must
use the key to lock then unlock Model S again
before starting the vehicle.
Everything you need to know when driving
Model S displays on the instrument panel.
Key Not Inside
If Model S does not detect a key when you
press the brake, the instrument panel displays
a message telling you that a key is not inside.
If you receive this message, place the key in
the center console cup holder where Model S
can best detect it.
If Model S still does not detect the key, try holding it against the center console,
immediately below the 12V power socket (see
12V Power Socket on page 22). Or try using
another key. If another key does not work, contact Tesla.
A number of factors can affect whether
Model S can detect the key. These include a
low battery in the key, interference from other
devices using radio signals, and objects
between the key and receiver.
Always keep the key with you. After driving,
the key is needed to restart Model S after it
powers off. And when you leave Model S, you
must bring the key with you to lock Model S, either manually or automatically.
Powering Off
When you finish driving, shift into Park by
pressing the button on the end of the gear selector. The parking brake automatically
engages and all systems keep operating.
When you leave Model S with the key, it
powers off automatically, turning off the
instrument panel and touchscreen.
Model S also powers off automatically after
being in Park for 15 minutes, even if you are
sitting in the driver

to cold weather conditions. If Model S is plugged in, you can heat your Battery by
turning on climate control with the mobile app. The snow

Caution: If the brakes are not functioning
properly, stop the vehicle as soon as safety permits and contact Tesla Service.
See Park on page 52 for information on
using the Park button to stop the vehicle
in case of emergency.Warning: Always maintain a safe driving
distance from the vehicle in front of you
and be cautious in hazardous driving
conditions. Do not rely on brake disc
wiping or hydraulic fade compensation to act as a substitute for adequate braking.
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 reducing or
removing pressure from the accelerator pedal
to slow down, you can take advantage of regenerative 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 when your foot is
completely off the accelerator pedal at
highway speeds), the brake lights turn on to
alert others that you are slowing down.
Warning: In snowy or icy conditions
Model S may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 67)
in snowy or icy conditions to help maintain vehicle stability.
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 44).
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. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed yellow line displays on the power
meter.
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:

range. In addition to heating the Battery, thesesettings also cool the battery when necessary
(for example, while driving at high speeds,
during rapid acceleration, driving for long
periods, etc.).
Launch Mode
Launch Mode, available on Performance All-
Wheel Drive vehicles only, provides optimum acceleration on surfaces with good traction.
Note: Hard acceleration including, but not
limited to, using launch mode, increases stress
on the vehicle
