that either do not exist or are not in the
lane of travel, causing Model S to slow
down unnecessarily or inappropriately.
Warning: Traffic-Aware Cruise Control
may be unable to provide adequate
speed control because of limited braking
capability and hills. It can also misjudge
the distance from a vehicle ahead. Driving
downhill can increase driving speed,
causing Model S to exceed your set speed
(and potentially the road's speed limit).
Never depend on Traffic-Aware Cruise
Control to slow down the vehicle enough
to prevent a collision. Always keep your
eyes on the road when driving and be
prepared to take corrective action as
needed. Depending on Traffic-Aware
Cruise Control to slow the vehicle down
enough to prevent a collision can result in
serious injury or death.
Changing the Set Speed
To change the set speed while using Traffic-
Aware Cruise Control, move the cruise control
lever up (increase) or down (decrease) until
your desired set speed is displayed.
Autopilot
Traffic-Aware Cruise Control
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.
Note: It may take a few seconds for Model S to
reach the new cruising speed, assuming
Model S does not detect a vehicle ahead
driving slower than your set speed.
HOLD State
When following a vehicle, Traffic-Aware Cruise
Control remains active at low speeds, even
when Model S comes to a full stop. When the
vehicle is moving again, Traffic-Aware Cruise
Control resumes operating at the set speed.
However, under the following circumstances,
Traffic-Aware Cruise Control goes into a HOLD
state, in which case, you need to briefly press
the accelerator pedal or pull the cruise control
lever toward you (see
Resuming on page 87) to resume cruising.
When the HOLD status is active, the
instrument panel displays the HOLD icon and
a message that indicates that you need to
resume cruise control. The following
circumstances can cause Traffic-Aware Cruise
Control to go into the HOLD state:
• Model S has been at a standstill for 5
minutes.
• Model S detects a pedestrian (the HOLD
state may clear when the pedestrian is no
longer detected).
• Model S suddenly loses visibility of the
vehicle in front of you.
• The ultrasonic sensors detect an obstacle
in front of Model S.
