Wipers and Washers
Wipers
To wipe the windshield, rotate the end of the
left-hand steering column lever away from
you. The steering column lever has five
positions:

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 119). The washer de-icers turn off when
the heated wipers turn off (after 15 minutes),
provided the temperature is warm enough to prevent freezing.

Brakes
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

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 68)
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 47).
The amount of energy fed back to the Battery using regenerative braking can depend on thecurrent 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:

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.

Traction Control
How It Works The traction control system constantly
monitors the speed of the front and rear
wheels. If Model S experiences a loss of
traction, the system minimizes wheel spin by
controlling brake pressure and motor power.
By default, the traction control system is on. Under normal conditions, it should remain on
to ensure maximum safety.

Park Assist
How Park Assist Works
Model S has several sensors designed to detect the presence of objects. When drivingslowly in Drive or Reverse (for example, when
parking), the sensors alert you if an object is
detected in close proximity of your Model S.
Objects are only detected in the direction of
the gear you selected; front objects in Drive,
rear objects in Reverse.
Warning: You may not be alerted if
Model S rolls freely in the opposite
direction of the gear you selected (for
example, you will not receive an alert if
Model S rolls backwards down a hill while
in Drive).
The sensors are activated when driving slower
than 8 km/h.
Warning: Never depend on Park Assist to
inform you if an area you are approaching is free of objects and/or people. Several
external factors can reduce the
performance of Park Assist, causingeither no readings or false readings (see
Limitations and False Warnings on page
72). Therefore, depending on Park Assist
to determine if Model S is approaching an obstruction can result in damage to the
vehicle and/or objects, and can
potentially cause serious injury. Always
inspect the area with your own eyes.
When reversing, perform shoulder checks and use all mirrors. Park assist does not
detect children, pedestrians, bicyclists,
animals, or objects that are moving, protruding, located too far above or
below the sensors, or too close or too far
from the sensors. Park Assist is for
guidance purposes only and is not intended to replace your own direct visual
checks. It is not a substitute for careful
driving.
Visual and Audio Feedback
When you shift to Reverse, the Park Assist
view displays on the left side of the instrument
panel, showing objects that are in close
proximity to the front and rear of Model S.
This view closes when you shift into Drive
unless an object is detected close to the front
of Model S, in which case the Park Assist view
closes automatically when your driving speed
exceeds 8 km/h. When reversing, visual
feedback also displays on the touchscreen, immediately below the camera view (see Rear
View Camera on page 80). You can manually
close the park assist view on the touchscreen by touching the X in the upper left corner.
When driving with the Camera app displayed on the touchscreen, you can switch to the
Park Assist view when driving at speeds below
8 km/h. Touch the button located in the upper
left corner of the Camera app window. This is
useful if you need assistance with parallel parking.
If chimes are turned on (see Controlling
Audible Feedback on page 72), an audible
beep sounds as you approach an object. You
can temporarily mute the chime by pressing
the scroll button on the left side of the
steering wheel or by touching the mute button on the bottom left corner of the Park Assist
view.
Note: If a sensor is unable to provide
feedback, the instrument panel displays an
alert message.
Caution: Keep sensors clean from dirt,
debris, snow, and ice. Avoid using a high
pressure power washer on the sensors
