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
). The fluid
level can be seen by looking at the outside
marks on the side of the reservoir.
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.
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
