Anti-Lock Braking System (Abs); Traction Control - Tesla Roadster 2 Owner's Manual

The amount of regenerative braking can vary
depending on the current state of the
Battery. For example, you'll experience a loss
of regenerative braking if the Battery is
extremely hot or cold or if the Battery has
already been charged to its maximum
allowable level using the Range or
Performance charge setting.
You'll also experience a loss of regenerative
braking in slippery road conditions—when
this occurs, the traction control indicator on
the instrument panel may flash and you may
experience that the brakes feel slightly
different. This is not a cause for concern.
When regenerative braking is not
available or has been significantly
reduce, a warning indicator illuminates on the
instrument panel.
Anti-lock Braking System
(ABS)
WARNING: ABS cannot overcome
physical limitations such as stopping
the vehicle in too short a distance, turning the
vehicle at high speeds, or the lack of grip on
the road's surface.
WARNING: Do not take driving risks
and hope that ABS will correct
judgement errors. It is always your
responsibility to drive with due care and
attention.
Your vehicle is equipped with an anti-lock
braking system (ABS) that prevents the
wheels from locking when you apply
Driving your vehicle
maximum brake pressure. This allows you to
maintain steering control during heavy
braking on 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 ABS is operating and
is not a cause for concern. Keep firm and
steady pressure on the brake pedal while
experiencing the pulsation.
Emergency braking
WARNING: DO NOT pump the foot
brake. ABS does this for you and by
pumping the foot brake yourself, you are
interfering with ABS operation, which may
increase braking distance.
In an emergency, fully press the brake pedal
even when the road surface is slippery. ABS
will vary the braking pressure to each wheel
according to the amount of traction available.
This prevents the wheels from locking and
ensures that the vehicle stops as safely as
possible.
Note: ABS operates only when control of the
vehicle is jeopardized. It can not compensate
for driver error.
ABS warning indicator
When the key is turned to the ON position,
and also at frequent intervals while driving,
the ABS checks that all its components are
operating correctly.
Driving basics
If a fault is detected, the warning
BRAKE
indicator in the instrument panel
flashes and the ABS shuts down. Contact
Tesla Motors as soon as possible.
The vehicle's brakes remain fully operational
and are not affected by an ABS failure.
However, braking distances may increase and
wheels may lock under heavy braking.

Traction control

WARNING: Traction control cannot
overcome the physical limitations of the
vehicle turning at too high a speed and
cannot prevent any accident which may
result.
The traction control system
TC
constantly monitors the difference in
speed between the front and rear wheels. If a
loss of traction is detected, it reduces torque
to the rear wheels to minimize wheel spin.
When this happens, you may notice the
traction control warning indicator on the
instrument panel illuminate briefly.
Traction control is automatically switched on
each time the key is turned to the ON
position. The traction control button on the
center console illuminates amber to indicate
the vehicle's traction control system is
operating.
Note: For safety reasons, you can not drive
without traction control when using cruise
control. If you disable traction control, cruise
control will also be disabled. Or, if you are
