Note: Your set speed will use your current
driving speed if you move the cruise control
lever up or down.
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.
Warning: Do not rely on Speed Assist or
Trac-Aware Cruise Control to
determine an accurate or appropriate
cruising speed. Always cruise at a safe
speed based on road conditions and
applicable speed limits.
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 set speed is displayed.
To increase/decrease speed by 1 km/h, move
the lever up or down to the first position and
release. To increase/decrease speed to the
closest 5 km/h increment, move the lever up/
down to the second position and release. For
example, if you are traveling at 83 km/h and
you move the lever up to the second position
and release, the speed increases to 85 km/h.
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. See Speed Assist on
page 112.
Note: It may take a few seconds for Model X
to reach the new cruising speed, assuming
Model X does not detect a vehicle ahead
driving slower than your set speed.
Overtake Acceleration
When following a vehicle with Trac-Aware
Cruise Control active, briefly engaging the
turn signal (to indicate a move into the
passing lane) accelerates Model X 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 accelerates only when the following
conditions are met:
•
Trac-Aware Cruise Control is operating
and detects a vehicle in front of you.
• No obstacles or vehicles are detected in
the target lane.
• Model X 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,
Trac-Aware
Cruise Control continues to maintain distance
from the vehicle ahead, but allows you to drive
slightly closer than your selected distance.
Acceleration cancels when:
• You reach your set cruising speed.
• Changing lanes takes too long.
• Model X 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 X stops
accelerating (in the same way as when you
release the accelerator pedal) and resumes
the set speed.
Warning:
Overtake Acceleration can
cancel for many unforeseen reasons in
addition to those listed above (for
example, lack of GPS data). Stay alert and
