{Warning
Cruise control can be dangerous
where you cannot drive safely at a
steady speed. Do not use cruise
control on winding roads or in
heavy traffic.
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could
lose control. Do not use cruise
control on slippery roads.
With cruise control, a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot
on the accelerator. Cruise control does
not work at speeds below about
40 km/h (25 mph). If the Traction Control System (TCS)
or StabiliTrak/Electronic Stability
Control (ESC) begins to limit wheel
spin while using cruise control, the
cruise control automatically
disengages. See
Traction Control/
Electronic Stability Control 0203. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision Alert
(FCA) System 0226. When road
conditions allow cruise control to be
safely used, it can be turned back on.
Cruise control will disengage if either
TCS or StabiliTrak/ESC is turned off.
If the brakes are applied, cruise
control disengages.

J.
Erasing Speed Memory
The cruise control set speed is erased
from memory if
Jis pressed or if
the ignition is turned off.
Adaptive Cruise Control
If equipped with Adaptive Cruise
Control (ACC), it allows the driver to
select the cruise control set speed and
following gap. Read this entire section
before using this system. The
following gap is the following time
between your vehicle and a vehicle
detected directly ahead in your path,
moving in the same direction. If no
vehicle is detected in your path, ACC
works like regular cruise control. ACC
uses camera and radar sensors. See
Radio Frequency Statement 0350.
If a vehicle is detected in your path,
ACC can apply acceleration or limited,
moderate braking to maintain the
selected following gap. To disengage
ACC, apply the brake. If ACC is controlling your vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control
(ESC) system activates, the ACC may
automatically disengage. See
Traction
Control/Electronic Stability Control
0 203. When road conditions allow
ACC to be safely used, the ACC can be
turned back on.
ACC will not engage if the TCS or
StabiliTrak/ESC system is disabled.
{Warning
ACC has limited braking ability and
may not have time to slow the
vehicle down enough to avoid a
collision with another vehicle you
are following. This can occur when
vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver” in this section.
Complete attention is always
required while driving and you
should be ready to take action and
apply the brakes. See Defensive
Driving 0174.
{Warning
ACC will not detect or brake for
children, pedestrians, animals,
or other objects.
Do not use ACC when:
. On winding and hilly roads or
when the sensors are blocked
by snow, ice, or dirt. The
system may not detect a
vehicle ahead. Keep the entire
front of the vehicle clean.
. Visibility is low, such as in
fog, rain, or snow conditions.
ACC performance is limited
under these conditions.
. On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.

DRIVING AND OPERATING 211
Warning (Continued)
control is in before using the
feature. If ACC is not active, the
vehicle will not automatically brake
for other vehicles, which could
cause a crash if the brakes are not
applied manually. You and others
could be seriously injured or killed.
Setting Adaptive Cruise Control
If
Jis on when not in use, it could
get pressed and go into cruise when
not desired. Keep
Joff when cruise
is not being used.
Select the set speed desired for cruise.
This is the vehicle speed when no
vehicle is detected in its path.
ACC will not set at a speed less than
25 km/h (16 mph), although it can be
resumed when driving at lower
speeds.
To set ACC while moving:
1. Press
J.
2. Get up to the desired speed. 3. Move the thumbwheel down
toward SET–.
4. Remove your foot from the accelerator.
After ACC is set, it may immediately
apply the brakes if a vehicle ahead is
detected closer than the selected
following gap.
ACC can also be set while the vehicle
is stopped if ACC is on and the brake
pedal is applied.
The ACC indicator displays on the
instrument cluster and Head-Up
Display (HUD), if equipped. When ACC
is turned on, the indicator will be lit
white. When ACC is engaged, the
indicator will turn green.
Be mindful of speed limits,
surrounding traffic speeds, and
weather conditions when selecting the
set speed. Resuming a Set Speed
If the ACC is set at a desired speed
and then the brakes are applied, ACC
is disengaged without erasing the set
speed from memory.
To begin using ACC again, move the
thumbwheel up toward RES+ briefly.
The vehicle returns to the previous set
speed.
.
If the vehicle is moving, it returns
to the previous set speed.
. If the vehicle is stopped with the
brake pedal applied, move the
thumbwheel up toward RES+ and
release the brake pedal. ACC will
hold the vehicle until the
thumbwheel is moved up toward
RES+ or the accelerator pedal is
pressed.

212 DRIVING AND OPERATING
Once ACC has resumed, if there is no
vehicle ahead, if the vehicle ahead is
beyond the selected following gap,
or if the vehicle has exited a sharp
curve, then the vehicle speed will
increase to the set speed.
Increasing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
.Use the accelerator to get to the
higher speed. Move the
thumbwheel down toward SET– .
Release the control and the
accelerator pedal. The vehicle will
now cruise at the higher speed.
When the accelerator pedal is
pressed, ACC will not brake
because it is overridden. The ACC
indicator will turn blue on the
instrument panel and HUD,
if equipped. See Vehicle Messages
0 148.
. Move the thumbwheel up toward
RES+ until the desired set speed
appears on the display, then
release it. .
To increase vehicle speed in small
increments, move the thumbwheel
up toward RES+ to the first detent.
For each press, the vehicle goes
1 km/h (1 mph) faster.
. To increase vehicle speed in larger
increments, move the thumbwheel
up toward RES+ to the second
detent. For each press, the vehicle
speed increases to the next 5 km/h
(5 mph) mark on the speedometer.
The set speed can also be increased
while the vehicle is stopped.
. If stopped with the brake applied,
move the thumbwheel up toward
RES+ until the desired set speed is
displayed.
. If ACC is holding the vehicle at a
stop and there is another vehicle
directly ahead, moving the
thumbwheel up toward RES+ will
increase the set speed. Moving the
thumbwheel up toward RES+ when
there is no longer a vehicle ahead
will cause the ACC to resume. When it is determined that there is no
vehicle ahead or the vehicle ahead is
beyond the selected following gap,
then the vehicle speed will increase to
the set speed.
The speedometer reading can be
displayed in either English or metric
units. See
Instrument Cluster 0126.
The increment value used depends on
the units displayed.
Reducing Speed While ACC is at a
Set Speed
If ACC is already activated, do one of
the following:
. Use the brake to get to the desired
lower speed. Release the brake and
move the thumbwheel down
toward SET– . The vehicle will
now cruise at the lower speed.
. Hold the thumbwheel down
toward SET– until the desired
lower speed is reached, then
release it.
. To decrease the vehicle speed in
smaller increments, move the
thumbwheel down toward SET− to

Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display.
The vehicle ahead indicator only
displays when a vehicle is detected in
your vehicle’s path moving in the
same direction.
If this symbol is not displaying, ACC
will not respond to or brake for
vehicles ahead.
ACC automatically slows the vehicle
down and adjusts vehicle speed to
follow the vehicle in front at the
selected follow gap. The vehicle speed
increases or decreases to follow the
vehicle in front of you, but will not
exceed the set speed. It may apply
limited braking, if necessary. When
braking is active, the brake lamps will come on. The automatic braking may
feel or sound different than if the
brakes were applied manually. This is
normal.
Stationary or Very Slow-Moving
Objects
{Warning
ACC may not detect and react to
stopped or slow-moving vehicles
ahead of you. For example, the
system may not brake for a vehicle
it has never detected moving. This
can occur in stop-and-go traffic or
when a vehicle suddenly appears
due to a vehicle ahead changing
lanes. Your vehicle may not stop
and could cause a crash. Use
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
ACC Automatically Disengages
ACC may automatically disengage and
the driver will need to manually apply
the brakes to slow the vehicle when:
.
The sensors are blocked.
. The Traction Control System (TCS)
or StabiliTrak/ESC system has
activated or been disabled.
. There is a fault in the system.
. The radar falsely reports blockage
when driving in a desert or remote
area with no other vehicles or
roadside objects. A DIC message
may display to indicate that ACC
is temporarily unavailable.
The ACC indicator will turn white
when ACC is no longer active.
Notification to Resume ACC
ACC will maintain a follow gap behind
a detected vehicle and slow your
vehicle to a stop behind that vehicle.
If the stopped vehicle ahead has
driven away and ACC has not
resumed, the vehicle ahead indicator
will flash as a reminder to check
traffic ahead before proceeding. In

addition, the left and right sides of the
Safety Alert Seat will pulse three
times, or three beeps will sound. See
”Alert Type”and “Adaptive Cruise Go
Notifier” in“Collision/Detection
Systems” underVehicle Personalization
0 149.
When the vehicle ahead drives away,
move the thumbwheel up toward
RES+ or press the accelerator pedal to
resume cruise control. If stopped for
more than two minutes or if the driver
door is opened and the driver seat belt
is unbuckled, the ACC automatically
applies the Electric Parking Brake
(EPB) to hold the vehicle. The EPB
status light will turn on. See Electric
Parking Brake 0201. To release the
EPB, press the accelerator pedal.
A DIC warning message may display
indicating to shift to P (Park) before
exiting the vehicle. See Vehicle
Messages 0148.{Warning
If ACC has stopped the vehicle, and
if ACC is disengaged, turned off,
or canceled, the vehicle will no
longer be held at a stop. The vehicle
can move. When ACC is holding the
vehicle at a stop, always be
prepared to manually apply the
brakes.
{Warning
Leaving the vehicle without placing
it in P (Park) can be dangerous. Do
not leave the vehicle while it is
being held at a stop by ACC. Always
place the vehicle in P (Park) and
turn off the ignition before leaving
the vehicle.
ACC Override
If using the accelerator pedal while
ACC is active, the ACC indicator turns
blue on the instrument cluster and in
the HUD (if equipped) to indicate that automatic braking will not occur. ACC
will resume operation when the
accelerator pedal is not being pressed.
{Warning
The ACC will not automatically
apply the brakes if your foot is
resting on the accelerator pedal.
You could crash into a vehicle
ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a
vehicle ahead in your lane. You
could be startled if the vehicle
accelerates up to the set speed,
especially when following a vehicle
exiting or entering exit ramps. You
could lose control of the vehicle or
crash. Do not use ACC while driving
on an entrance or exit ramp. Always
be ready to use the brakes if
necessary.

12017481) - 2019 - CRC - 11/5/18
216 DRIVING AND OPERATING
{Warning
On curves, ACC may respond to a
vehicle in another lane, or may not
have time to react to a vehicle in
your lane. You could crash into a
vehicle ahead of you, or lose control
of your vehicle. Give extra attention
in curves and be ready to use the
brakes if necessary. Select an
appropriate speed while driving in
curves.
ACC may operate differently in a
sharp curve. It may reduce the vehicle
speed if the curve is too sharp.
When following a vehicle and entering
a curve, ACC may not detect the
vehicle ahead and may accelerate to
the set speed. When this happens, the
vehicle ahead indicator will not
appear.
ACC may detect a vehicle that is not
in your lane and apply the brakes.
ACC may occasionally provide an alert
and/or braking that is considered
unnecessary. It could respond to
vehicles in different lanes, signs,
guardrails, and other stationary
objects when entering or exiting a
curve. This is normal operation. The
vehicle does not need service. Other Vehicle Lane Changes
ACC will not detect a vehicle ahead
until it is completely in the lane. The
brakes may need to be manually
applied.
Do Not Use ACC on Hills and When
Towing a Trailer
