2018 TESLA MODEL S ECU

7.Displays
Manually control the brightness and the DAY (light background) or NIGHT (dark background)
setting of the touchscreen and instrument panel. When set to AUTO, the brightness changes
automatically between day and night brightness based on ambient lighting conditions. When
Auto-adjust is checked, the displays are further adjusted based on both the surroundings and
by learning your preferences (i.e. it remembers the type of manual adjustments you make).
To disable the touchscreen momentarily for cleaning purposes, touch CLEAN MODE.
You can also put Model S into an energy saving mode so it consumes less energy when not in
use (see Getting Maximum Range on page 70).
Note: The Displays settings can also be accessed from the Controls screen.
8. HomeLink (if equipped)
If the HomeLink feature is available in your region, use it to control RF-enabled garage doors, lights, or security systems (see HomeLink Universal Transceiver on page 133).
9. Driver Assistance
If Model S is equipped with Driver Assistance components, you can control the features that provide a safer and more convenient driving experience (see About Driver Assistance on page
73).
10. Service & Reset
Turn various service-related features on and
off:

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 112).
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 104). 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 temperature
popup that appears when you touch an arrow.
3. Touch the fan icon to customize and automate climate control settings (See Customizing
Climate Control on page 112.)
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.
Note: The label on this button says Keep Climate On if you have set the climate control system
to maintain your temperature settings when parked (see Customizing Climate Control on
page 112).
6. The rear window defroster warms up the rear window for 15 minutes, then automatically shuts
off. 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 heater 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, neurological injury, or some other condition, should exercise caution when using the climate control
system and seat heaters.

About the Security SystemIf Model S does not detect a key nearby and a
locked door or trunk is opened, an alarm sounds and the 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 you exit,
the doors lock, and a recognized key is no
longer detected.
If your Model S is equipped with the optional security package, it includes a battery-backed
siren that sounds in situations where a locked door or trunk is opened and Model S does notdetect a key nearby. If the Tilt/Intrusion
setting is on, the siren also sounds if Model S
detects motion inside the cabin or if the
vehicle is moved or tilted (for example, with a
tow truck or jack). To temporarily turn the Tilt/
Intrusion detection system
off, touch
Controls > Settings > Safety & Security > Tilt/
Intrusion > OFF . The Tilt/Intrusion setting is
enabled every time Model S is unlocked.
Note: If you plan to leave something that
moves, such as a dog, inside your locked
Model S, remember to turn
off Tilt/Intrusion .
Motion detected inside Model S activates the
siren.
Note: The Alarm must be on to enable Tilt/
Intrusion .

Checking Brake FluidWarning: Contact Tesla immediately if
you notice increased movement of the brake pedal or a
significant loss of brakefluid. Driving under these conditions can
result in extended stopping distances or complete brake failure.
The Brake indicator on the
instrument panel alerts you if the
quantity of
fluid in the brake
reservoir drops below the
recommended level. If it displays
while driving, stop as soon as safety
permits by gently applying the
brakes. Do not continue driving.
Contact Tesla immediately.
Fluid Level Check
Tesla checks the brake
fluid level at the
regularly scheduled maintenance intervals. To
check it yourself, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see Removing the
Maintenance Panel on page 159).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir
without removing the
filler cap.
The brake
fluid level should always be
between the MIN and the MAX marks.
Note: Although brake
fluid level drops slightly
during normal use as a result of brake pad
wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake
fluid. Tesla service
does this when you bring Model S in for
regular servicing. The following instructions
are provided for information purposes and future reference only:
1. Clean the filler cap before removing it to
prevent dirt from entering the reservoir.
2. Unscrew the cap and remove it.
3. Top up the reservoir to the MAX mark
using the appropriate brake
fluid.4. Replace the filler cap, ensuring it is fully
secured.
Warning: Only use new fluid from a
sealed air-tight container. Never use
previously used
fluid or fluid from a
previously opened container

2.Remove the tow eye cover by inserting a
small flat screwdriver into the slot located
along the top of the cover, then prying gently to release the cover from the top
snapCaution: Keep the tow eye cover in a
safe place so you can replace it when
towing is complete.
3. Fully insert the tow eye into the opening,
then turn it counter-clockwise until
securely fastened.
4. Attach the winch cable to the tow eye.
Caution:
Before pulling, make sure
the tow eye is securely tightened.
5. Pull Model S slowly onto the flatbed truck.
6. Shift Model S into Park by pressing the
button on the end of the gear selector.
If not equipped with a tow eye:
1. Attach the tow straps to the large hole on
each of the rearmost lower suspension
arms underneath the front of the vehicle.
2. To protect the underbody from any
damage, place a protective barrier (such
as a piece of wood) between the tow
strap and the underbody.
3. Pull Model S slowly onto the
flatbed truck.
4. Shift Model S into Park by pressing the
button on the end of the gear selector.
