Press the interior release button to open the
front trunk, then push up on the hood.
Note: The interior release button glows
following a brief exposure to ambient light.
Warning: People should never climb
inside the front trunk. Never shut the
front trunk when a person is inside.Warning: Care should be taken to ensure
that objects inside the front trunk do not
bump against the release button, causing the trunk to accidentally open.
Opening Hood with No Power
In the unlikely event that Model 3 has no 12V power, you will be unable to open the front
trunk using the touchscreen, key fob, or
mobile app. To open the front trunk in this situation:
Note: The following will not open the front
trunk if Model 3 is locked and has 12V power.
1. Locate an external 12V power supply
(such as a portable jump starter).
2. Release the tow eye cover by pressing
firmly on the top right perimeter of the
cover until it pivots inward, then gently pulling the raised section toward you.
Note: Depending on production date,
either the positive or negative terminal
may be attached to the tow eye cover.
3. Pull the two wires out of the tow eye
opening to expose both terminals.
4. Connect the 12V power supply
Note: The parking brake operates on the rear
wheels only, and is independent of the pedal-
operated brake system.
Warning: In snowy or icy conditions the
rear wheels may not have sufficient
traction to prevent Model 3 from sliding
down a slope, particularly if not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always responsible for parking safely.Warning: Your Model 3 may display an
alert if the road is too steep to safely park
on, or if the parking brakes are not
properly engaged. These alerts are for
guidance purposes only and are not a
substitute for the driver’s judgment of safe parking conditions, including specific
road or weather conditions. Do not
depend on these alerts to determine
whether or not it is safe to park at any location. You are always responsible for
parking safely.When you use the touchscreen to
manually apply the parking brake,
the red parking brake indicator lights
up on the touchscreen.If the parking brake experiences an
electrical issue, the amber parking brake indicator lights up and a fault
message displays at the top of the
touchscreen.Caution: In the unlikely event that Model 3
loses electrical power, you cannot access
the touchscreen and are therefore unable to release the parking brake without first
jump starting Model 3 (see Instructions
for Transporters on page 199).Brake Wear
Model 3 brake pads are equipped with wear indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as
it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their service life and require replacement. To
replace the brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by removing the tire and wheel. For detailed
specifications and service limits for rotors and
brake pads, see Subsystems on page 188.
Additionally, Tesla recommends cleaning and
lubricating the brake calipers every year or
12,500 miles (20,000 km) if in an area where
roads are salted during winter months.Warning: Neglecting to replace worn
brake pads damages the braking system
and can result in a braking hazard.

Battery Information
About the Battery
Model 3 has one of the most sophisticated
battery systems in the world. The most
important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN when
you are not using it. This is particularly important if you are not planning to drive
Model 3 for several weeks. When plugged in,
Model 3 wakes up when needed to
automatically maintain a charge level that
maximizes the lifetime of the Battery.
Note: When left idle and unplugged, your
vehicle periodically uses energy from the Battery for system tests and recharging the
12V battery when necessary.
There is no advantage to waiting until the
Battery’s level is low before charging. In fact, the Battery performs best when charged
regularly.
Note: If you allow the Battery to discharge to
0%, other components may become damaged
or require replacement (for example, the 12V
battery). In these cases, you are responsible for repair and/or transporting expenses.
Discharge-related expenses are not covered
by the warranty or under the Roadside
Assistance policy.
The peak charging rate of the Battery may
decrease slightly after a large number of DC
Fast Charging sessions, such as those at
Superchargers. To ensure maximum driving
range and Battery safety, the Battery charge
rate is decreased when the Battery is too cold,
when the Battery’s charge is nearly full, and when the Battery conditions change with
usage and age. These changes in the condition of the Battery are driven by battery physics
and may increase the total Supercharging
duration by a few minutes over time.
Battery Care
Never allow the Battery to fully discharge.
Even when Model 3 is not being driven, its
Battery discharges very slowly to power the
onboard electronics. The Battery can
discharge at a rate of approximately 1% per day, though the discharge rate may vary
depending on environmental factors (such as
cold weather), vehicle configuration, and your
selected settings on the touchscreen.
Situations can arise in which you must leave
Model 3 unplugged for an extended period of time (for example, at an airport when
traveling). In these situations, keep the 1% in
mind to ensure that you leave the Battery with a sufficient charge level. For example, over a
two week period (14 days), the Battery may
discharge by approximately 14%.
Discharging the Battery to 0% may result in
damage to vehicle components. To protect
against a complete discharge, Model 3 enters
a low-power consumption mode when the
displayed charge level drops to approximately
0%. In this mode, the Battery stops supporting
the onboard electronics and auxiliary 12V
battery. Once this low-power consumption
mode is active, immediately plug in Model 3 to
prevent a jump-start and 12V battery
replacement.
Note: If the vehicle is unresponsive and will
not unlock, open, or charge, then the 12V
battery may have become discharged. In this
situation, contact Tesla.
Temperature Limits
For better long-term performance, avoid
exposing Model 3 to ambient temperatures
above 140
