Driving your vehicle
Hand brake
WARNING: Do not apply the hand
brake when the vehicle is moving. This
could result in a loss of control and may
damage the rear brakes.
S
The hand brake operates on the rear wheels
only, and is totally independent of the foot
operated hydraulic brake system.
To apply the hand brake, pull the lever fully
upwards.
If the starter switch is in the ON
position and the hand brake is
applied, the warnin g indicator in the
instrument panel illuminates and the Touch
Screen will display the main Parked screen.
Caution: If the hand brake is applied
when the brakes are hot (such as after
prolonged or frequent hard use), care should
be taken that the hand brake is securely
engaged. As the brake discs cool, the amount
of brake force applied by the lever will
reduce. To release the hand brake, pull the lever up
slightly, depress the button (shown in
illustration) and fully lower the lever. The
warning indicator will extinguish and the
Touch Screen will display a Drive screen.
Braking
WARNING: After driving through heavy
rain, some loss of braking response may
be experienced. As soon as safety permits,
apply the brakes to generate heat and dry the
brake components. Never drive the vehicle
through deep water - doing so can cause
damage and void the New Vehicle Limited
Wa r ra n t y.
S
The brakes operate through dual circuits. If
one circuit fails, the other continues to
function, but brakin g performance is
reduced. If greater pedal effort, or longer
stopping distances are experienced, the car
should not be driven and Tesla Motors should
be contacted as soon as possible. The brakes are servo-assisted, but only when
the starter switch is in the ON position and
the electrical systems are operating. Without
servo assistance, greater pedal effort is
required to control the vehicle, resulting in
longer stopping distances.
Regenerative brakingWhenever the vehicle is moving and your
foot is off the accelerator, regenerative
braking slows the vehicle and feeds energy
back to the battery. By anticipating your
stops and simply removing your foot from
the accelerator to slow down, you can take
advantage of the energy gains of
regenerative braking. A visual display on the
instrument panel provides real-time
feedback of the vehicle’s regenerative
braking. See
LCD panel, page 6-11 .Anti-lock Braking System
(ABS)
WARNING: ABS cannot overcome the
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.
S
WARNING: Do not take risks when
driving in the hope that ABS will correct
errors of judgement. In all cases it is the
driver's responsibility to drive with due care
and attention.
S
Your vehicle is equipp ed with an anti-lock
braking system (ABS) that prevents the
wheels from locking when maximum brake

pressure is applied. 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
result in an increase in braking distance.
S
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 indicatorWhen the starter switch is turned to the ON
position, and also at frequent intervals while
driving, the ABS checks that all its
components are operating correctly. If a fault is detected, the warning
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.
Tra c t i o n c o n t ro l
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.S
The traction control system 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 flash
quickly.
Traction control is automatically switched on
each time the starter switch is turned to the
ON position.Switching off traction controlIf required, traction control can be manually
switched off by pressing and holding the
switch on the center console for
approximately two seconds. When the
button is released, traction control will be
disabled. The warning indicator in the
instrument panel illuminates to inform
you that the vehicle is operating without the
advantages of traction control.
Under normal conditions, traction control
should be left on. The system should only be
switched off in circumstances where you
deliberately want the wheels to slip. As soon
as the circumstances requiring you to switch
traction control off have passed, press the
switch to turn traction control back on.BRAKE
