The gray speedometer icon

on the instrument panel

turns blue and displays the

set speed to indicate that

Trac-Aware Cruise Control

is active.

Note: The minimum set speed is 30 km/h. The

maximum set speed is 150 km/h. It is the

driver's responsibility to cruise at a safe speed

based on road conditions and speed limits.

You can now release the accelerator pedal and

allow

Trac-Aware Cruise Control to maintain

your set speed. When no vehicle is detected

ahead,

Trac-Aware Cruise Control maintains

the set speed. If a vehicle is detected, Trac-

Aware Cruise Control maintains your chosen

following distance, up to the set speed,

accelerating and decelerating Model X as

needed. When the vehicle you are following is

no longer detected,

Trac-Aware Cruise

Control accelerates up to the set speed.

Trac-Aware Cruise Control also adjusts the

speed as appropriate when entering and

exiting curves.

You can manually accelerate at any time when

driving at a set speed using

Trac-Aware

Cruise Control. But when you release the

accelerator, Model X returns to the set speed.

When following a vehicle, Trac-Aware Cruise

Control remains active at low speeds, even if

Model X comes to a standstill. When the

vehicle is moving again,

Trac-Aware Cruise

Control resumes operating at your current set

speed. However, under the following

circumstances,

Trac-Aware Cruise Control

goes into a HOLD state instead of resuming,

and the instrument panel displays a message

indicating that you need to resume cruise

control:

• You have been at a standstill for 5

minutes.

• The driver's seat belt is unbuckled.

• Model X detects a pedestrian nearby (the

HOLD state may clear when the

pedestrian is no longer close by).

• Model X suddenly loses visibility of the

vehicle you are following.

• The ultrasonic sensors detect an obstacle

in front of Model X.

To resume Trac-Aware Cruise Control, press

the accelerator pedal or pull the cruise control

lever toward you (see Canceling and

Resuming on page 95).

In right hand

trac, engaging the right turn

signal when driving in the right-most lane

within 50 meters of an exit (on a controlled

access road only, such as a highway or

freeway), causes

Trac-Aware Cruise Control

to assume you are exiting. As a result,

Trac-

Aware Cruise Control begins to slow down the

vehicle. Likewise in left hand trac, when

engaging the left turn signal when driving in

the left-most lane within 50 meters of an exit.

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 X.

Note: If you double-pull the cruise control

lever (or single-pull when Trac-Aware Cruise

Control is active), Autosteer activates if

enabled (see Autosteer on page 97) and the

set speed changes to either your current

driving speed, or the speed limit plus any

oset you have deﬁned in Speed Assist,

whichever is greater (see Cruising at the

Speed Limit on page 93).

Note: When

Trac-Aware Cruise Control is

actively slowing down Model X to maintain the

selected distance from the vehicle ahead, the

brake lights turn on to alert other road users

that you are slowing down. You may also

notice slight movement of the brake pedal.

However, when

Trac-Aware Cruise Control is

accelerating Model X, the accelerator pedal

does not move.

Warning:

Due to limitations inherent in

the onboard GPS, you may experience

situations in which Trac-Aware Cruise

Control slows down the vehicle, especially

near highway exits where a curve is

detected and/or you are actively

navigating to a destination and not

following the route.

Warning: Trac-Aware Cruise Control

cannot detect all objects and may not
