Using the touchscreens, you can pinpoint exactly where you want to direct the air flowing from
this vent when heating or cooling the cabin. When the face-level vent is on you can adjust the
direction of the air
flow from each vent. To adjust the direction of the air flow, touch the
radiating air waves from the corresponding vent on the touchscreen. The air flows in a single
stream when centered or splits into mirrored air streams when air is directed outward or inward
from the center of the vent.

Removing the Maintenance
Panel
To 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
Your Battery coolant should not need to be
replaced for the life of your vehicle under
most circumstances. However, if the quantity
of
fluid in the cooling system drops below the
recommended level, the instrument panel displays a warning message. Stop driving Model S as soon as safety permits and
contact Tesla.
Fluid Level Check
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 specific
mixture of G-48 ethylene-glycol coolant
(HOAT). Contact Tesla for more specific information about the coolant.
Checking Brake Fluid
WARNING: Contact Tesla immediately if you notice increased movement of the brake pedal or a significant loss of brake fluid. Driving under these conditions can result in extended stopping distances or complete brake failure.
A red 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 and health
at the regularly scheduled maintenance intervals.
Topping Up the Brake Fluid
Do not top up your brake fluid. 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
