2020 TESLA MODEL Y ECU

CAUTION: Sentry Mode may not trigger the
security alarm in all situations involving damage to
the vehicle. The security alarm depends upon
multiple factors to be triggered and may not
detect all impacts to the vehicle or may not trigger
the alarm in all cases.
Standby, Alert, and Alarm States
When in Sentry Mode, Model Y may go through three
states depending on its surroundings

1. Place the curved part of the lug nut cover tool (located in the glovebox for some vehicles, or you can use a small allen wrench) into the lowered
perimeter around the middle of the lug nut cover.
NOTE: The lug nut cover tool can also be purchased
at an auto parts store or through online retailers.
2.
Twist the lug nut cover tool so that the end of the curved part is facing away from the Tesla "T".
3.
Firmly pull the lug nut tool away from the wheel until the lug nut cover is released.
To install the lug nut cover:
1.
Align the lug nut cover into position.
2.
Push firmly on the lug nut cover until it fully snaps
into place.
CAUTION: Make sure the lug nut cover is fully
secure before driving to prevent it from falling
off.
Tire Pressure Monitoring
Each tire should be checked monthly when cold and
inflated to the recommended pressures that are printed
on the Tire and Loading Information label located on the
driver’s door pillar (see Maintaining Tire Pressures on
page 164). If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire
inflation pressure label, determine the proper tire
inflation pressure for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that displays a tire pressure telltale (Tire Pressure Warning) on the
touchscreen when
one or more of your tires is
significantly under-inflated.
Accordingly, when the Tire Pressure indicator light
displays on the
touchscreen to alert you about tire
pressure, stop and check your tires as soon as possible, and
inflate them to the proper pressure (see Maintaining
Tire Pressures on page 164). Driving on a significantly

under-inflated tire causes the tire to overheat and can
lead to tire failure.
Under-inflation also reduces range
e

Regularly inspect the exterior paint for damage. Treat minor chips and scratches using a paint touch-up pen (available for purchase from Tesla). Use the touch-up
pen after washing but before polishing or waxing.
Repair rock chips, fractures or scratches. Refer to
https://www.tesla.com/support/body-shop-support for
more information on repair locations and available
services.
CAUTION: Do not use cutting pastes, color
restoration compounds, or polishes containing
harsh abrasives. These can scour the surface and
permanently damage the paint.
CAUTION: Do not use chrome polish or other
abrasive cleaners.
Using a Car Cover
To preserve the cosmetic appearance of the body when
Model Y is not being used, use a genuine Tesla car
cover. Car covers can be purchased from Tesla. See
Parts and Accessories on page 177.
CAUTION: Use only a Tesla-approved car cover
when Model Y is plugged in. Using a non-Tesla car
cover can prevent the Battery from being
adequately cooled during charging.
Floor Mats
To extend the life of your carpet and make them easier
to clean, use genuine Tesla
floor mats (see Parts and
Accessories on page 177). Maintain floor mats by
regularly cleaning them and checking that they are
properly attached. Replace
floor mats if they become
excessively worn.
WARNING: To avoid potential interference with a
foot pedal, ensure that the driver’s floor mat is
securely fastened, and never place an additional
floor mat on top of it. Floor mats should always
rest on top of the vehicle carpeting surface and
not on another floor mat or other covering.
Cleaning
172MODEL Y OWNER

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.
3.
If checking the Battery coolant, remove the cabin intake trim panel by pulling it upwards 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
touchscreen
displays a warning message. Stop driving Model Y 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 touchscreen 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 FluidWARNING: 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
touchscreen 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.
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.
Replace 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
