2018 TESLA MODEL X cooling

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 127).
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/cooling pads. When operating, the top indicator
turns red when heating or the bottom indicator turns blue when cooling.
Note: If Model X 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 119).
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 for the front and rear
cabin. (See Customizing Climate Control on page 127.)
Note: Rear climate controls are available only if Model X is equipped with six or seven seating
positions.
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 127).
6. The rear window defroster warms up the rear window for 15 minutes, then automatically shuts
off. Exterior side mirrors are also heated.
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.

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. You can even keep the climate control system on while you are away from the vehicle so that the
selected temperature is maintained.
To override the automatic setting, touch FRONT or REAR to customize individual settings for the
front or rear seating areas. Then touch the setting you want to change. Touch RESET AUTO to
change all settings on the panel back to their defaults. Or, you can touch AUTO associated with
any individual setting to change it back to its default.
Note: Rear climate controls are available only if Model X is equipped with six or seven seating
positions.
In addition to the five settings shown above (and described below), if Model X is in Park, a Climate
Timer displays below the above popup (see Keep Climate On on page 130).
1. Touch RESET AUTO to change all settings on the currently displayed customization panel
back to their default values.
2. Touch A/C ON or A/C OFF to turn the air conditioning on and
off, respectively. Turning it offreduces cooling, but saves energy.
Because Model X runs much quieter than a gasoline-powered vehicle, you may notice thesound of the A/C compressor as it is operating. To minimize noise, reduce the fan speed.

Rear Cabin Climate Controls (6 and 7 seat vehicles only)
Note: When set to AUTO, the rear heating and air conditioning turn off when Model X detects that
there are no occupants in the second or third row seats. To override this energy saving feature and
save the settings until you manually change them, touch the AUTO button located above the
Climate On/Climate
Off setting. Touching AUTO a second time cancels your manual setting and
resumes the energy saving feature.
1. Touch RESET AUTO to change all settings back to their default values.
2. Touch CLIMATE ON or CLIMATE OFF to turn the air conditioning on and
off, respectively.
Turning it off reduces cooling, but saves energy.
Note: Because Model X runs much quieter than a gasoline-powered vehicle, you may notice
the sound of the A/C compressor as it is operating. To minimize noise, reduce the fan speed
or recirculate the air.
3. Touch the arrows to adjust the temperature.
4. Touch the arrows to set the speed of the fan.

Removing the Maintenance PanelTo check
fluid levels, remove the maintenance
panel:
1. Open the hood.
2. Pull the maintenance panel upward to
release the clips that hold it in place.
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 driving Model X as soon as safety
permits and contact Tesla.
Fluid Level Check
Tesla checks the Battery coolant level at the
regularly scheduled maintenance intervals.
DO NOT REMOVE THE FILLER CAP AND DO NOT ADD FLUID. Doing so can result in
damage not covered by the warranty.
Do Not Top Up Battery Coolant
Warning: Battery coolant can be
hazardous and can irritate eyes and skin.
Under no circumstances should you
remove the
filler cap and/or add coolant.
If the instrument panel warns you that the
fluid level is low, contact Tesla
immediately.
To maximize the performance and life of the
Battery, the cooling system uses a specificmixture of G-48 ethylene-glycol coolant
(HOAT). Contact Tesla for more specificinformation about the coolant.
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.
Topping Up the Brake Fluid
Do not top up your brake
fluid. Tesla service
does this when you bring Model X 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
