Testing a Child Safety Seat
Before seating a child, always make sure the
child safety seat is not loose:
1. Hold the child safety seat by the belt path and try to slide the safety seat from side
to side and front to back.
2. If the seat moves more than one inch (2.5 cm), it is too loose. Tighten the belt or
reconnect the LATCH retained child safety
seat.
3. If you are unable to reduce slack, try a
different seat location or try another child
safety seat.
Warnings - Child Safety Seats
Warning: Extreme hazard! Do not seat a
child on the front passenger seat even if
you are using a child safety seat. This seat
has an airbag in front of it. Although this airbag is disabled when Model S detects a
lightweight passenger, do not rely on technology to protect your child.Warning: Child restraint systems are
designed to be secured in vehicle seats
by lap belts or the lap belt portion of a lap-shoulder belt. Children could be
endangered in a crash if their child restraints are not properly secured in the
vehicleWarning: According to accident statistics,
children are safer when properly
restrained in the rear seating positions
than in the front seating positions.Warning: Do not use a forward facing child safety seat until your child weighs
over 20 lbs (9 kg) and can sit
independently. Up to the age of two, a
child

little or no light is detected.
You can also manually turn an individual dome light on or
off by pressing its lens. If you
manually turn a dome light on, it turns off when Model S powers off. If Model S was already
powered off when you manually turned the light on, it turns off after 60 minutes.
2. If you turn on AMBIENT lights, the lights on the door armrests turn on whenever the headlights are on.
3. If you turn on AUTO HIGH BEAM, high beam headlights turn on and
off automatically based
on whether or not light is detected in front of Model S (see High Beam Headlights on page
51). This feature is available only if Model S is equipped with the optional Autopilot Tech Package.
4. Touch to turn fog lights (if equipped) on or
off. Fog lights operate only when low beam
headlights are on. Fog lights do not operate when headlights are turned off or when high
beam headlights are on.
The Front Fog indicator displays on the instrument panel whenever front fog
lights are on.
Note: Depending on the market region and vehicle options, your vehicle may not be equipped
with front and/or rear fog lights.
Note: In some regions, there is no control for the front fog lights. They operate in conjunction
with the headlights and turn on only in situations where low beam headlights are on.

If Model S is equipped with Driver Assistance
components (see About Driver Assistance on
page 65), and you have purchased the
optional Autopilot Tech Package, the high
beam headlights can automatically switch to low beam when there is light detected in front
of Model S (for example, from an oncoming vehicle or street lights). To turn this feature on,touch Controls > Auto High Beam.
Note: Your chosen setting is retained until you manually change it. It can also be saved in
your driver
profile.
In situations where high beams are turned offbecause Auto High Beam is turned on and
light is detected in front of Model S, you can
temporarily turn on high beams by pulling the
lever all the way toward you.
The following indicator light islights are visible
on the instrument panel when high beams are
turned on:

left).
The turn signals stop operating when canceled by the steering wheel, or when you return the
lever to the central position.
The corresponding turn signal
indicator lights up on the instrument
panel when a turn signal is
operating. You also hear a clicking
sound.Warning: If Model S is equipped with both
Autopilot hardware and the optional
Autopilot Tech Package, and
Traffic-
Aware Cruise Control is active, engaging
a turn signal can cause Model S to accelerate when using
Traffic-AwareCruise Control in specific situations (see
Overtake Acceleration on page 70).
Warning: If Model S is equipped with both

Braking Systems
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 flashes briefly on
the instrument panel when you firststart Model S. If this indicator lights
up at any other time, an ABS fault
has occurred and the ABS is not
operating. Contact Tesla. The braking system remains fully operational and
is not
affected by an ABS failure.
However, braking distances may increase.
If the instrument panel displays this
indicator at any time other than
displaying
briefly when you first start
Model S, a brake system fault is
detected or the brake
fluid level is
low. Contact Tesla immediately.
Emergency Braking
In an emergency, fully press the brake pedal and maintain
firm pressure, even on low
traction surfaces. The ABS varies the braking
pressure to each wheel according to the
amount of traction available. This prevents
wheels from locking and ensures that you stop
as safely as possible.
Warning: Do not pump the brake pedal.
Doing so interrupts operation of the ABS
and can increase braking distance.Warning: Always maintain a safe distance
from the vehicle in front of you and be
aware of hazardous driving conditions.
While the ABS can improve stopping
distance, it cannot overcome the laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of
water prevents direct contact between the tires and the road).
If Model S is equipped with Autopilot
hardware, Automatic Emergency Braking
automatically applies full braking in situations
where a collision is considered imminent (see
Automatic Emergency Braking on page 86).
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 stop
the squealing, contact Tesla Service.
Warning: Neglecting to replace worn
brake pads results in damage to the
braking system and can create a braking
hazard.

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 simply
removing pressure from the accelerator to slow down, you can take advantage ofregenerative 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 on a steep descent,
brake lights turn on to alert other road users
that you are slowing down.
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 37).
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. If regenerative
braking is limited, a dashed yellow line
displays on the power meter. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is low.
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 Model S is stopped, Vehicle Holdcontinues to apply the brakes even after you
remove your foot from the brake pedal. When
driving on a hill or on a
flat surface, brake as
you normally would. You can release the brake
pedal, and remain stopped (even on a hill),
whenever the instrument panel displays the
Vehicle Hold indicator light.
This indicator displays on the
instrument panel whenever Vehicle
Hold is engaged.
To disengage Vehicle Hold, press the
accelerator pedal or press and release the
brake pedal.
Note: Shifting into Neutral also disengages Vehicle Hold.
Note: After actively braking Model S for
approximately 10 minutes, Model S shifts into
Park and Vehicle Hold cancels. Model S also shifts into Park if it detects that the driver has
left the vehicle.
