2020 TESLA MODEL S ECU

Gears
Shifting Gears When Model S is in Park, you must press the
brake to shift to another gear.
Move the lever up or down to change gears.
If you try to shift into a gear that the current
driving speed prohibits, a chime sounds and
the gear does not change.
Reverse
Push the lever all the way up and release. You
can only shift into Reverse when Model S is
stopped or moving less than 5 mph (8 km/h).
If moving less than 1 mph (1.6 km/h), you must
press the brake.
Neutral
Push the lever up or down to the first position
and release to shift into Neutral. Neutral allows
Model S to roll freely when you are not
pressing the brake pedal.
If Model S is in Park and you use the
touchscreen to release the parking brake
( Controls > Safety & Security ), Model S shifts
into Neutral (see Parking Brake on page 68).
Drive
Push the lever all the way down and release.
You can shift into Drive when Model S is stopped or moving less than 5 mph (8 km/h)in Reverse. If Model S is moving less than
1 mph (1.6 km/h), you must press the brake to shift into Drive.
Park
Press the end of the gear selector while
Model S is stopped. Whenever Model S is in Park, the parking brake is applied.
Model S automatically shifts into Park
whenever you connect a charge cable or if
two or more of the following conditions are
met simultaneously while traveling slower than
approximately 1.5 mph (2 km/h):

When Tow mode is active, Model S
displays this indicator light on the
instrument panel, along with a
message telling you that Model S will
roll freely.
Note: In Tow mode, Model S does not shift into
a driving gear. To cancel Tow mode, shift into
Park or touch Tow mode again. Tow mode also
cancels if you use the touchscreen to apply
the parking brake ( Controls > Safety &
Security > Parking Brake ).

Driving53

Use the touchscreen to manually release the
parking brake (which also shifts Model S into Neutral):
1. Touch Controls > Safety & Security .
2. Press the brake pedal, then touch Parking
Brake . If Model S was previously in Park, it
shifts into Neutral.When you use the touchscreen to
manually apply the parking brake,
the red parking brake indicator lights
up on the instrument panel.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
instrument panel.Caution: In the unlikely event that Model S
loses electrical power, you cannot access
the touchscreen and are therefore unable to release the parking brake. Contact
Tesla.
Brake Wear
Model S 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 194.
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.

Limitations and False Warnings The parking sensors may not function
correctly in these situations:

Safety & Security

Note: You can direct the outer face level vents
toward the side windows to help defrost or
defog them.
Cabin Air Filter
Model S has an air filter that prevents pollen,
industrial fallout, road dust and other particles
from entering through the vents. Tesla
recommends replacing the cabin air filter
every 2 years.
Tesla recommends replacing the HEPA air
filter (if equipped) every 3 years.
Cabin Overheat Protection
The climate control system can reduce the
temperature of the cabin in extremely hot
ambient conditions for a period of up to twelve hours after you exit Model S. TouchControls > Safety & Security > Cabin Overheat

For security reasons, if you sell Model S, it isrecommended that you delete your Home and
Work Locations. You can delete these
individually or you can perform a factory reset to erase all personal data (see Erasing
Personal Data on page 127).
Map Updates As updated maps become available, they are
automatically sent to Model S over Wi-Fi. To
ensure you receive them, periodically connect Model S to a Wi-Fi network (see Connecting
to Wi-Fi on page 156). The touchscreen
displays a message informing you when new
maps are installed.
