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.

How It WorksThe 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
always active. Under normal conditions, it should remain active to ensure maximum
safety.
On standard (single motor) Model S vehicles,
traction control can be turned
off at any time.
Turn it off only in circumstances where you
deliberately want the wheels to spin, such as
when Model S is stuck in snow or mud.
On a dual motor Model S, you can enable slip
start to allow the wheels to spin at a limited speed. Slip start can be enabled only when
Model S is moving 20 mph (32 km/h) or
slower. Slip start automatically disables when
the speed exceeds 40 mph (64 km/h).
This indicator flashes on the
instrument panel whenever the
traction control system is actively
controlling brake pressure and motor
power to minimize wheel spin. If the
indicator stays on, a fault is detected with the traction control system.
Contact Tesla Service.Warning: Traction control can not prevent
accidents caused by driving dangerously
or turning too sharply at high speeds.Warning: If the above indicator remains
illuminated without turning off traction
control (single motor vehicles) or
enabling slip start (dual motor vehicles), the traction control system may not be
operating correctly. Contact Tesla Service immediately.
Disabling Traction Control (single motor
vehicles)
Under normal conditions, the traction control
system should remain enabled. Disable it only
in circumstances where you deliberately want
the wheels to spin, such as:

Checking Brake FluidWarning: Contact Tesla immediately if you
notice increased movement of the brake
pedal or a
significant loss of brake fluid.Driving under these conditions can result in extended stopping distances or
complete brake failure.
The Brake indicator on the
instrument panel alerts you if the
quantity of
fluid in the brake
reservoir drops below the
recommended level. If it displays
while driving, stop as soon as safety
permits by gently applying the
brakes. Do not continue driving.
Contact Tesla immediately.
Fluid Level Check
Tesla checks the brake
fluid level at the
regularly scheduled maintenance intervals. To
check it yourself, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see Removing the
Maintenance Panel on page 149).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir
without removing the
filler cap.
The brake
fluid level should always be
between the MIN and the MAX marks.
Note: Although brake
fluid level drops slightly
during normal use as a result of brake pad
wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake
fluid. Tesla service
does this when you bring Model S in for
regular servicing. The following instructions
are provided for information purposes and future reference only:
1. Clean the filler cap before removing to
prevent dirt from entering the reservoir.
2. Unscrew the cap and remove.
3. Top up the reservoir to the MAX mark using brake
fluid meeting DOT3specifications.4. Replace the filler cap.
Warning: Only use new fluid from a sealed
air-tight container. Never use previously
used
fluid or fluid from a previously
opened container

Use a Flatbed OnlyUse a
flatbed trailer only, unless otherwisespecified by Tesla. Do not transport Model S
with the tires directly on the ground.
Caution: Damage caused by transporting is not covered by the warranty.Caution: To transport Model S, follow theinstructions exactly as described next.
Disable Self-Leveling (air
suspension vehicles only)
If Model S is equipped with Smart AirSuspension, it automatically self-levels, even
when power is
off. To prevent damage, you
must activate Jack mode to disable self- leveling:
1. Touch Controls > Suspension on the touchscreen.
2. Press the brake pedal, then touch Very High to maximize height.
3. Touch Jack.
When Jack mode is active,
Model S displays this indicator
light on the instrument panel,
along with a message telling you
that active suspension is
disabled.
Note: Jack mode cancels when Model S is
driven over 4.5 mph (7 km/h).
Warning: Failure to activate Jack mode on
a Model S equipped with Smart Air Suspension can result in the vehicle
becoming loose during transport, which
may cause
significant damage.
Activate Tow Mode
Model S may automatically shift into Park
when it detects the driver leaving the vehicle,
even if it has previously been shifted into Neutral. To keep Model S in Neutral (which
disengages the parking brake), you must use
the touchscreen to activate Tow mode:
1. Shift into Park.
2. Press the brake pedal, then on the touchscreen, touch Controls > Settings >
Service & Reset > Tow Mode.When Tow mode is active, Model S
displays this indicator light on the
instrument panel, along with a
message telling you that Model S is
free-rolling.
Note: Tow mode cancels when Model S is
shifted into Park.
Caution: If the electrical system is not
working, and you therefore cannot release
the electric parking brake, attempt to
quick start the 12V battery. For
instructions, call Tesla. If a situation
occurs where you cannot disengage the
parking brake, use tire skids or transport Model S for the shortest possible distance
using wheeled dollies. Before doing so,
always check the dolly manufacturer
