2015 TESLA MODEL S cooling

1.Close
Touch the circled X in the top left corner
of a window to close it (or you can touch anywhere outside the window).
2. Sunroof
If Model S is equipped with a sunroof,
touch to adjust its position (see Sunroof
on page 15).
3. Suspension
If Model S is equipped with Smart Air
Suspension, touch to manually raise or lower Model S, or to remove a previously
saved auto-raising location (see Smart Air
Suspension on page 83). Model S must
be powered on and you must press the
brake pedal before you can change
suspension settings. Smart Air Suspension
causes Model S to self-level, even when
powered off. Therefore, when towing or
lifting, you must disable self-leveling (see
Instructions for Transporters on page 150
and Jacking and Lifting on page 132).
4. Driving
• Steering mode Adjust the amount of effort requiredto turn the steering wheel. Sport feels
more responsive whereas Comfort
feels easier to drive and park (see
Steering Wheel on page 37).
• Acceleration (Dual Motor vehicles only)
Choose an acceleration level. Sport is the standard level of acceleration and allows you to maximize driving range(see the Range Mode setting below).
Choose Insane if you want to increase
peak torque by approximately 50 per cent. If you choose Insane, the Range
mode setting, if on, automatically turns off.
• Creep
When on, Model S slowly movesforward when in Drive and backward
in Reverse when you release the brake
(similar to a conventional vehicle with an automatic transmission). You can
adjust this setting only when Model S
is in Park.
• Traction ControlTo allow the wheels to spin on a
standard single motor Model S, you can turn off traction control. On a dualmotor Model S, you can enable Slip
Start. If you turn off Traction Control
(or enable Slip Start), a warning
message displays on the instrument
panel. Traction control turns off for
the current drive only. On dual motor
vehicles, traction control is
automatically turned on again when the speed exceeds 40 mph
(64 km/h). See Traction Control on
page 54.
• Regenerative braking
When you release the accelerator
when driving, regenerative braking
slows Model S and feeds any surplus
energy back to the Battery. If set to
Low, Model S does not slow down as
quickly, but you may experience less range (see Regenerative Braking on
page 53).
Note: Regardless of the setting, the
energy gained by regenerative
braking is reduced if the Battery is
full, or if it is extremely cold or hot
(the surplus energy is used to heat or
cool the Battery).
• Range Mode
If on, Model S conserves energy by
limiting the power of the climate
control system. Cabin heating and
cooling may be less effective, but seat
heaters turn on to compensate. In
Dual Motor vehicles, Range Mode can
be turned on only when acceleration
is set to Sport (see above).
5. Cold Weather
If Model S is equipped with the cold
weather option, you can control all seat heaters as well as the heated wipers andsteering wheel. Heaters that are turned on
are displayed in red. To turn off all seat
heaters, touch All Off. Note that you can
also control the front driver and
passenger seats using the main climate
control panel located on the bottom of
the touchscreen (see Climate Controls on
page 80).
6. Trips
View and reset the trip meters that
summarize how far you have driven (see
Trip Information on page 69).

Customizing Climate ControlThe climate control system is designed to automatically provide optimum comfort in most
situations. All you need to do is set the desired temperature, and the air conditioning, air
recirculation, air distribution, and fan speed automatically maintain your selected temperature.
To override the automatic setting, touch AUTO ON to view the individual settings. Then touch the
setting you want to change. When you change a setting, the AUTO ON icon turns from blue to
gray and RESET AUTO displays instead.
1.Touch RESET AUTO to change all settings
back to the their default values.
2. Touch A/C ON or A/C OFF to turn the air
conditioning on and off, respectively. Turning it off reduces cooling, but saves
energy.
Because Model S runs much quieter than a gasoline-powered vehicle, you may notice
the sound of the compressor as it is
operating. To minimize noise, reduce the
fan speed or recirculate the air.
3. Choose how air is drawn into Model S:
Outside air is drawn into
Model S (see Ventilation on
page 82). Although less
efficient than recirculating the
air in very hot or low climate
conditions, this setting draws
more air into the rear seating
areas, and is recommended
when occupants are seated in
the Tesla built-in rear facing
child seats.Air inside Model S is
recirculated. This prevents
outside air (traffic fumes) from
entering but reduces
dehumidifying and cooling
performance. Recirculating the
air is the most efficient way to
cool the front cabin area but it
is also the loudest. To prevent
the windshield from fogging in
some conditions, briefly change
the setting every hour to draw
in outside air.
4. Choose where air flows into the cabin.
You can choose more than one location:
Foot-level ventsFace-level ventsWindshield vents
5. Drag the slider to set the speed of the fan.

Using the Touchscreen81

Ventilation
Outside air is drawn into Model S through the
grill in front of the windshield. Keep the grill
clear of obstructions such as leaves and snow.
To direct the flow of air inside Model S, move
the interior vents up, down, or from side to
side.
Note: You can direct the outer face level vents
toward the side windows to help defrost or defog them.
Cabin Air Filter
Model S has an air filter that prevents pollen,
industrial fallout, road dust and other particles
from entering through the vents. Tesla replaces the air filter at the regularly
scheduled maintenance intervals of every 12 months, or every 12,500 miles (20,000 km).
Climate Control Operating Tips
• To conserve energy, you can limit the power of the climate control system by
turning on Range Mode. Cabin heating and cooling may be less effective, butseat heaters turn on to compensate.
Touch Controls > Driving > Range Mode .
• If the climate control system operates more loudly than you prefer, reduce thefan speed or adjust the air flow to draw in
outside air (instead of recirculating).
• In addition to cooling the interior, the air conditioning system also cools the
Battery. Therefore, in hot weather, the air
conditioning system can turn on even if
you turned it off. This is normal because the system’s priority is to cool the Battery
to ensure it stays within an optimum
temperature range to support long life and optimum performance.
• To ensure the climate control system operates efficiently, close all windows and
ensure that the exterior grill in front of the
windshield is free of ice, snow, leaves, and
other debris.
• To reduce the time it takes to reach a comfortable temperature in hot weather,
drive with the windows slightly open for a
few minutes when you first start driving.
• In very humid conditions, it is normal for the windshield to fog slightly when you
first turn on the air conditioning. This fog
clears within a few seconds.
• It is normal for a small pool of water to form under Model S when parked. Extra
water produced by the dehumidifying
process is drained underneath.

Opening the Charge Port
The charge port is located on the driver’s side of Model S, behind a door that is part of therear tail light assembly.
Park Model S so that the charge cable easily
reaches the charge port.
With Model S unlocked, or a recognized key
nearby, press and release the button on a
Tesla charge cable to open the charge port door. If the cable you are using does not havethis button, you can also open the charge portdoor using any of these methods:
• Touch Controls > Charge Port on the
touchscreen.
• Touch the battery icon at the top of the touchscreen to display the Charging
screen, then touch Open Charge Port.
• Hold down the rear trunk button on the key for 1-2 seconds.
To charge at a public charging station, attach
an adapter to the station’s chargingconnector. The most commonly usedadapter(s) for each market region aresupplied with Model S. Depending on thecharging equipment you are using, you may
need to start and stop charging using a control on the charging equipment.
Note: The charge port lights up white when
you open the charge port door. If you do not
connect a charge cable, the light eventually
turns off.
Note: If you do not insert the charge cable
into the charge port within a few minutes after
opening the charge port door, the latch
closes. If this happens, use the touchscreen to
open the charge port door.Caution: The connector end of the charge
cable can damage the paint if dropped onto Model S.Caution: Do not attempt to force the
charge port door open. Doing so can
damage the latch. A damaged latch
cannot hold the door closed.
Plugging In
If desired, use the touchscreen to change the
charge limit and the charging current.
If you are using the Mobile Connector, plug it into the power outlet before plugging it intoModel S.
Align the connector to the charge port and
insert fully. When the connector is properly
inserted, charging begins automatically after Model S:
• Engages a latch that holds the connector in place.
• Shifts into Park (if it was in any other gear).
• Heats or cools the Battery, if needed. If the Battery requires heating or cooling,
you may notice a delay before charging begins.
Note: Whenever Model S is plugged in but not
actively charging, it draws energy from the wall instead of using energy stored in the
Battery. For example, if you are sitting in
Model S and using the touchscreen while it’s is
parked and plugged in, the energy being used
is drawn from the power outlet instead of the
Battery.

Service Intervals
Regular maintenance is the key to ensuring
the continued reliability and efficiency of your
Model S.
Rotate the tires every 5000 miles (8000 km),
maintain the correct tire pressures, and take Model S to Tesla at the regularly scheduledmaintenance intervals of every 12 months, orevery 12,500 miles (20,000 km), whichever
comes first. It is also important to perform the
daily and monthly checks described below.
Model S must be serviced by Tesla-certified
technicians. Damages or failures caused by
maintenance or repairs performed by non-
Tesla certified technicians are not covered by
the warranty.
Daily Checks • Check the Battery’s charge level, displayed on the instrument panel.
• Check that all exterior lights, horn, turn signals, and wipers and washers are
working.
• Check the operation of the brakes, including the parking brake.
• Check the operation of the seat belts (see Seat Belts on page 20).
• Look for fluid deposits underneath Model S that might indicate a leak. It is
normal for a small pool of water to form
(caused by the air conditioning system’s dehumidifying process).
Monthly Checks • Check the mileage to determine if the tires need to be rotated (every
5000 miles/8000 km), and check the
condition and pressure of each tire (see
Tire Care and Maintenance on page 109).
• Check washer fluid level and top up if necessary (see Topping Up Washer Fluid
on page 125).
• Check that the air conditioning system is operating (see Climate Controls on page
80).Warning: Contact Tesla immediately if
you notice any significant or sudden drop in fluid levels or uneven tire wear.Fluid Replacement Intervals
Do not change or top up Battery coolant and
brake fluid yourself. Tesla service technicians replace fluids at the regularly scheduled
service intervals:
• Brake fluid. Every 2 years or 25,000 miles (40,000 km), whichever comes first.
• Battery coolant. Every 5 years or 62,500 miles (100,000 km), whichever
comes first.
Note: Any damage from opening the Battery
coolant reservoir is excluded from the warranty.
High Voltage Safety Your Model S has been designed and built
with safety as a priority. However, be aware of these precautions to protect yourself from the
risk of injury inherent in all high-voltage
systems:
• Read and follow all instructions provided on the labels that are attached to Model S.These labels are there for your safety.
• The high voltage system has no user- serviceable parts. Do not disassemble,
remove or replace high voltage components, cables or connectors. High
voltage cables are colored orange for
easy identification.
• If an accident occurs, do not touch any high voltage wiring, connectors, or
components connected to the wiring.
• In the unlikely event that a fire occurs, immediately contact your local fire
emergency responders.Warning: Always disconnect the charge
cable before working underneath Model S, even if charging is not in
progress.Warning: Keep your hands and clothing
away from cooling fans. Some fans
operate even when Model S is powered
off.Caution: Some fluids (battery acid,
Battery coolant, brake fluid, windshield
washer additives, etc.) used in motor
vehicles are poisonous and should not be
inhaled, swallowed, or brought into contact with open wounds. For your
safety, always read and follow
instructions printed on fluid containers.
Maintenance Schedule
108Model S Owner's Manual

Removing the Maintenance Panel
To access fuses and check fluid levels, remove the maintenance panel:
1. Pull the rear edge of the maintenance
panel upward to release the five clips that
hold the panel in place.
2. Maneuver the maintenance panel toward
the windshield to remove.Caution: The maintenance panel protects
the front trunk from water. When re- attaching, make sure it is fully seated.Checking Battery Coolant
If the quantity of fluid in the cooling system
drops below the recommended level, the
instrument panel displays a warning message.
Stop Model S as soon as safety permits and
contact Tesla.
Fluid Level Check
Tesla checks the Battery coolant 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 123).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir. DO
NOT REMOVE THE FILLER CAP AND DO NOT ADD FLUID. Doing so can result in damage
not covered by the warranty.
The fluid level should be between the MIN and
the MAX marks. If you notice that the fluid
level has dropped significantly, contact Tesla before using Model S.
Topping Up the Battery Coolant
Under no circumstances should you add coolant. If the instrument panel warns youthat the fluid level is low, contact Teslaimmediately.
To maximize the performance and life of the Battery, the cooling system uses a specific
type of G-48 ethylene-glycol coolant (HOAT).
Contact Tesla for more specific information
about the coolant.
