As you rotate the cruise control lever, the
instrument panel displays the current setting.
Release the lever when the desired setting is
displayed.
Cruising at the Speed Limit
Trac-Aware Cruise Control makes it easy to
cruise at the speed limit. Once you've initially
set a cruising speed, you can adjust the speed
to cruise at the speed limit that is currently
being determined by Speed Assist (see Speed
Assist on page 88). To do so, pull the cruise
control lever toward you and hold
momentarily (about half a second). When you
release, your cruising speed is set to the speed
that is automatically or manually being
determined by Speed Assist, taking into
consideration any
oset you have specified. If
you are already driving faster than the speed
limit when you pull and momentarily hold the
lever, the set speed does not adjust to the
speed limit—it adjusts to your current driving
speed.
Note: When you adjust the cruising speed
based on the speed limit, the set speed does
not change when the speed limit changes. You
must pull and hold the cruise control lever
again to cruise at the new speed limit. You can
also manually adjust your cruising speed at
any time (see Changing the Set Speed on
page 69).
Note: If Speed Assist is unable to determine a
speed limit, your set speed does not change
when you pull the cruise control lever toward
you and hold momentarily.
Warning: Do not rely on Speed Assist to
determine an accurate or appropriate
cruising speed. Always cruise at a safe
speed based on road conditions.
Changing the Set Speed
To change the set speed while using Trac-
Aware Cruise Control, move the cruise control
lever up (increase) or down (decrease) until
your desired speed is reached.
To increase/decrease speed by 1 mph (1
km/h), move the lever up or down to the first
position and release. To increase/decrease
speed to the closest 5 mph (5 km/h)
increment, move the lever up/down to the
second position and release. For example, if
you are traveling at 57 mph and you move the
lever up to the second position and release,
the speed increases to 60 mph. You can also
increase/decrease speed by holding the lever
in the full up/down position and releasing
when the desired speed displays below the
cruise control icon.
To cruise at the speed limit that is currently
being determined by Speed Assist (including
any
osets that you have set), pull the cruise
control lever toward you and hold
momentarily (about half a second). See Speed
Assist on page 88.
Note: It may take a few seconds for Model S to
reach the new cruising speed.
Note: The maximum set speed is 90 mph
(150 km/h).
