Removing the Maintenance Panel
To 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. On a single motor Model S, you can check it
yourself. To do so, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see Removing the
Maintenance Panel on page 154).
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 fluidlevel has dropped significantly, contact Tesla
before using Model S.
Topping Up the Battery Coolant
Warning: Battery coolant can be
hazardous and can irritate eyes and skin.
Under no circumstances should you 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 specifictype of G-48 ethylene-glycol coolant (HOAT).
Contact Tesla for more specific information
about the coolant.
