Fluid Reservoirs - Tesla MODEL X 2021 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 X 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.
226
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. Reinstall 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—fluid
absorbs moisture which decreases
braking performance.
