Tesla S - Page 98

NOTE: The onboard Global Positioning
System (GPS) determines if you are driving in
a region with right or left hand trac. In
situations where GPS data is unavailable (for
example, if there is inadequate signal),
engaging the turn signal near an exit does not
cause Trac-Aware Cruise Control to slow
down
Model S.
When enabled while on a highway
interchange or o-ramp in certain regions,
Trac-Aware Cruise Control may reduce your
set speed in
5 km/h increments – to as slow
as 40 km/h – to better match the reported
speeds of other Tesla vehicles that have
driven at that specific location. To override
this and continue cruising at your set speed,
tap the accelerator pedal or
move the cruise
stalk. The new set speed is maintained for the
duration of the interchange or
o-ramp
(unless you override it or cancel Trac-Aware
Cruise Control). After the interchange or o-
ramp, the set speed may revert or change as
necessary based on the new location. For
example, if you merged onto a
dierent
highway, the set speed reverts back to the set
speed that was in use before driving on the
interchange.
WARNING: In some cases (such as
having insucient data), Trac-Aware
Cruise Control may not automatically
reduce the set speed on the highway
interchange or o-ramp. Do not rely
on Trac-Aware Cruise Control to
determine an appropriate driving
speed. Tesla recommends driving at a
speed that is safe for road conditions
and within posted speed limits.
Adjust the Following Distance
To adjust the following distance you want to
maintain between
Model S and a vehicle
traveling ahead of you, rotate the cruise
control lever to choose a setting from 1 (the
closest following distance) to 7 (the longest
following distance). Each setting corresponds
to a time-based distance that represents how
long it takes for
Model S, from its current
location, to reach the location of the rear
bumper of the vehicle ahead of you.
As you rotate the cruise control lever, the
instrument panel displays the current setting.
Release the lever when the desired setting is
displayed.
NOTE: Your setting is retained until you
manually change it.
WARNING: It is the driver's
responsibility to determine and
maintain a safe following distance at
all times. Do not rely on Trac-Aware
Cruise Control to maintain an accurate
or appropriate following distance.
WARNING: Never depend on Trac-
Aware Cruise Control to adequately
slow down Model S to avoid a
collision. Always watch the road in
front of you and stay prepared to take
immediate corrective action.
Overtake Acceleration
When following a vehicle with Trac-Aware
Cruise Control active, briefly engaging the
turn signal (to indicate a move into the
passing lane) accelerates Model S towards the
vehicle ahead. By momentarily holding the
turn signal lever up or down, you can quickly
accelerate up to your set speed without
having to press the accelerator pedal. The
turn signal causes acceleration only when all
of the following conditions are met:
• Trac-Aware Cruise Control is operating
and detects a vehicle in front of you.
• No obstacles or vehicles are detected in
the target lane.
•
Model S is traveling below the set speed,
but over
72 km/h.
Overtake Acceleration is intended as an aid
when passing a vehicle ahead of you. When
the turn signal is engaged,
Trac-Aware
Cruise Control continues to maintain distance
from the vehicle ahead, but allows you to
drive slightly closer than your selected
distance.
