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 91). 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.
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 77).
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 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, pull the
cruise control lever toward you and hold
momentarily (about half a second). See Speed
Assist on page 91.
Note: It may take a few seconds for Model X
to reach the new cruising speed.
Overtake Acceleration
When following a vehicle with
Trac-Aware
Cruise Control active, engaging the turn signal
to indicate a move into the passing lane briefly
accelerates Model X 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 X only when the following
conditions are met:
•
Trac-Aware Cruise Control is operating
and detecting a vehicle in front.
• No obstacles or vehicles are detected in
the target lane.
• Model X 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,
Trac-Aware
Cruise Control continues to maintain distance
from the vehicle ahead, but allows you to drive
slightly closer than your selected distance.
Note: Model X uses its onboard GPS (Global
Positioning System) to determine if you are
driving in a region with right or left hand
trac. This enables the appropriate turn signal
to provide overtake acceleration. When
driving in right hand
trac, only the left turn
signal indicates a move into the passing lane.
In left hand
trac, only the right turn signal
(moving the turn signal lever up) indicates
Trac-Aware
Cruise Control
