Instrument Panel - DrivingWhen Model S is driving (or ready to drive), the instrument panel shows your current drivingstatus and a real-time visualization of the road as detected by the Autopilot components (see
About Autopilot on page 85). The visualization automatically zooms in and out as needed to
inform you when a vehicle is detected in your blind spot.
Note: The following illustration is provided for demonstration purposes only. Depending on vehicle
options, software version, and market region, the information displayed may be slightly different.
1.Indicator lights display along the top to provide status (see Instrument Panel Overview on
page 58).
2. When you are actively navigating to a destination, navigation instructions display here. Use
the left steering wheel buttons to change what displays on the left side of the instrument
panel whenever navigation instructions are not displayed (see Using Left Steering Wheel
Buttons on page 44).
3. Traffic-Aware Cruise Control is cruising at a set speed. When Traffic-Aware Cruise Control is

De-icing Washer Nozzles
If Model S is equipped with the optional cold weather package, washer nozzles have de-
icers that turn on whenever the ambient
temperature nears freezing, or when you turn
on the heated wipers (see Climate Controls on
page 128). The washer de-icers turn off when
the heated wipers turn off (after 15 minutes),
provided the temperature is warm enough to prevent freezing.

Braking and Stopping
Braking Systems
Warning: Properly functioning braking
systems are critical to ensure safety. If you experience a problem with the brake
pedal, brake caliper, or any component of
a Model S braking system, contact Tesla
immediately.
Model S has an anti-lock braking system (ABS) that prevents the wheels from locking
when you apply maximum brake pressure. This
improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according
to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep firm and
steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator brie

Caution: If the brakes are not functioning
properly, stop the vehicle as soon as safety permits and contact Tesla Service.
See Park on page 52 for information on
using the Park button to stop the vehicle
in case of emergency.Warning: Always maintain a safe driving
distance from the vehicle in front of you
and be cautious in hazardous driving
conditions. Do not rely on brake disc
wiping or hydraulic fade compensation to act as a substitute for adequate braking.
Regenerative Braking
Whenever Model S is moving and your foot is
off the accelerator, regenerative braking slows
down Model S and feeds any surplus energy
back to the Battery.
By anticipating your stops and reducing or
removing pressure from the accelerator pedal
to slow down, you can take advantage of regenerative braking to increase driving range.
Of course, this is no substitute for regular braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model S (such as when your foot is
completely off the accelerator pedal at
highway speeds), the brake lights turn on to
alert others that you are slowing down.
Warning: In snowy or icy conditions
Model S may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 67)
in snowy or icy conditions to help maintain vehicle stability.
The Energy app displays real-time feedback
on the amount of energy being gained by
regenerative braking. You can also display the
power meter on either side of the instrument
panel by choosing Energy using the scroll
button on the steering wheel (see Steering
Wheel on page 44).
The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed yellow line displays on the power
meter.
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:

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.
