Fluid Reservoirs - Tesla 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.
Maintenance
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
page 105).
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 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 type of
G-48 ethylene-glycol coolant (HOAT). Contact Tesla
for more specific information about the coolant.
