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.

Loading New Software
Model S updates its software wirelessly,
providing new features throughout your term of ownership. Tesla recommends that you
install software update as soon as they are
available. The
first time you enter Model S
after an update is made available, a scheduling
window displays on the touchscreen. The
scheduling window displays again at the end
of your
first driving session.
Note: Some software updates can take from
two to three hours to complete. Model S must be in P (Park) when the new software is being
installed. To ensure the fastest and most
reliable delivery of software updates, leave the
Wi-Fi turned on and connected whenever
possible (see Connecting to Wi-Fi on page
128).
When a software update is available, a yellow
clock icon appears on the touchscreen

Checking and Replacing Wiper
BladesCaution: Wiper blades do not lock into a lifted position. When cleaning or
replacing a wiper blade, lift the wiper arm
only a short distance from the windshield,
just far enough to access the blade. Do
not lift a wiper arm beyond its intended
position. Doing so can cause damage that
is not covered by the warranty.
To make wiper blades easy to access, turn offthe wipers, shift Model S into Park, then use
the touchscreen to move them to the service
position. Touch Controls > Settings > Service
& Reset > Service Mode > ON .
Note: Wipers automatically return to their
normal position when you shift Model S out of Park.
Periodically check and clean the edge of the wiper blade and check the rubber for cracks,
splits and roughness. If damaged, replace the blade immediately to prevent damage to the
glass.
Contaminants on the windshield, or on the wiper blades, can reduce the
effectiveness of
the wiper blades. Contaminants include ice,
wax spray from car washes, washer
fluid with
bug and/or water repellent, bird droppings,
tree sap, and other organic substances.
Follow these guidelines for cleaning:
