Fluid Reservoirs - Tesla S Owner's Manual

Fluid Reservoirs

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
On a Rear Wheel Drive Model S, you can
check the fluid level visually. BUT DO NOT
REMOVE THE FILLER CAP AND DO NOT ADD
FLUID. Doing so can result in damage not
covered by the warranty. To check the fluid
level, park Model S on level ground. When
Model S is cool, remove the maintenance
panel (see Removing the Maintenance Panel
on page 166). The fluid level can be seen by
looking at the outside marks on the side of the
reservoir.
166
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.
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.
