Overtake Acceleration
When following a vehicle with Traffic-Aware
Cruise Control active, engaging the turn signal
to indicate a move into the passing lane briefly
accelerates Model S towards the vehicle
ahead. By momentarily holding the turn signal
lever up or down (depending on the region
you are driving in), you can quickly accelerate
up to your set speed without having to press
the accelerator pedal. The turn signal
accelerates Model S only when the following
conditions are met:
• Traffic-Aware Cruise Control is operating
and detecting a vehicle in front.
• No obstacles or vehicles are detected in
the target lane.
• Model S is traveling below the set speed,
but over 72 km/h.
• The turn signal indicates a move into the
passing lane.
Overtake Acceleration is intended as an aid
when passing a vehicle ahead of you. When
the turn signal is engaged, Traffic-Aware
Cruise Control continues to maintain distance
from the vehicle ahead, but allows you to drive
slightly closer than your selected distance.
Note: Model S uses its onboard GPS (Global
Positioning System) to determine if you are
driving in a region with right or left hand
traffic. This enables the appropriate turn signal
to provide overtake acceleration. When
driving in right hand traffic, only the left turn
signal indicates a move into the passing lane.
In left hand traffic, only the right turn signal
(moving the turn signal lever up) indicates
passing. In situations where GPS data is
unavailable (for example, inadequate signal),
the turn signal does not activate Overtake
Acceleration.
Acceleration cancels when:
• You reach your set cruising speed.
• Changing lanes takes too long.
• Model S gets too close to the vehicle
ahead.
OR
• You disengage the turn signal.
Note: Overtake Acceleration occurs when you
either fully engage the turn signal, or you hold
the turn signal in the momentary position
(partially engaged). When you release or
disengage the turn signal, Model S stops
accelerating (in the same way as when you
release the accelerator pedal) and resumes
the set speed.
Driver Assistance
Traffic-Aware Cruise Control
Warning: Overtake Acceleration can
cancel for many unforeseen reasons in
addition to those listed above (for
example, lack of GPS data). Stay alert and
never depend on Overtake Acceleration
to increase your driving speed.
Warning: Overtake Acceleration increases
your driving speed whenever the
appropriate turn signal is engaged, and
accelerates Model S closer to the vehicle
ahead. Although Traffic-Aware Cruise
Control continues to maintain distance
from the vehicle ahead, it is important to
be aware that your selected following
distance is reduced when Overtake
Acceleration is active, particularly in cases
where it may not be your intention to
overtake the vehicle you are following.
