Cruise Control
{
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) system begins to limit
wheel spin while using cruise control,
cruise control automatically
disengages. See
Traction Control/
Electronic Stability Control 0247. If a
collision alert occurs when cruise
control is activated, cruise control is
disengaged. See Forward Collision Alert
(FCA) System 0287. 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: Press to turn the system on and
off. A white indicator appears in the
instrument cluster when cruise is
turned on.
RES+ : If there is a set speed in
memory, move the thumbwheel up
briefly to resume that speed or move
the thumbwheel up and hold to
accelerate. If cruise control is already
active, use to increase vehicle speed.
To increase speed by 1 km/h (1 mph),
press RES+ to the first detent. To
increase speed to the next 5 km/h
(5 mph) mark on the speedometer,
press RES+ to the second detent.

the desired speed, a green cruise
control indicator appears on the
instrument cluster and a cruise set
speed message appears on the
Head-Up Display (HUD), if equipped.
Resuming a Set Speed
If cruise control is set at a desired
speed and then the brakes are applied
or
*is pressed, cruise control is
disengaged without erasing the set
speed from memory.
Once the vehicle speed reaches about
40 km/h (25 mph) or more, move the
thumbwheel up toward RES+ briefly.
The vehicle returns to the previous set
speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is already
activated:
.Move the thumbwheel up toward
RES+ until the desired speed is
reached.
.To increase vehicle speed in small
increments, briefly press RES+ to
the first detent. For each press, the
vehicle goes about 1 km/h (1 mph)
faster.
.To increase vehicle speed in larger
increments, briefly press 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 speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0109.
The increment value used depends on
the units displayed.
Reducing Speed While Using Cruise

vehicle.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0109.
The increment value used depends on
the units displayed.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to increase
the vehicle speed. When you take your
foot off the pedal, the vehicle will slow
down to the previous set cruise speed.
While pressing the accelerator pedal
or shortly following the release to
override cruise, briefly moving the
thumbwheel down toward SET− will
result in cruise set to the current
vehicle speed. Using Cruise Control on Hills
How well cruise control will work on
hills depends upon the vehicle speed,
load, and the steepness of the hills.
When going up steep hills, you might
have to step on the accelerator pedal
to maintain speed. When going
downhill, the cruise control system
may automatically brake to slow the
vehicle. Also, you may have to brake
or shift to a lower gear to keep your
speed down. If the brake pedal is
applied, cruise control disengages.
Ending Cruise Control
There are four ways to end cruise
control:
.Step lightly on the brake pedal.
.Press*.
.Shift the transmission to
N (Neutral).
.PressJ.
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
(Advanced)
If equipped, Adaptive Cruise Control
(ACC) allows the cruise control set
speed and following gap to be
selected. 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 0421.
If a vehicle is detected in your path,
ACC can speed up the vehicle or apply
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 system activates, ACC
may automatically disengage. See
Traction Control/Electronic Stability
Control 0247. When road conditions
allow ACC to be safely used, ACC can
be turned back on.

2022 - CRC - 10/22/21
DRIVING AND OPERATING 253
Disabling the TCS or StabiliTrak/ESC
system will disengage and prevent
engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate,
especially when used on expressways,
freeways, and interstate highways.
When used on other roads, you may
need to take over the control of
braking or acceleration more often.
{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 0217.
{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 poor due to rain,
snow, fog, dirt, insect residue,
or dust; when other foreign
objects obscure the camera and/
or radar; or when the vehicle in
front or oncoming traffic causes
additional environmental
obstructions, such as road spray.
ACC performance is limited
under these conditions.
.On slippery roads where fast
changes in tire traction can
cause excessive wheel slip.
.Towing a trailer

Alerting the Driver
With Head-Up Display
Without Head-Up Display If ACC is engaged, driver action may
be required when ACC cannot apply
sufficient braking because of
approaching a vehicle too rapidly.
When this condition occurs, the
collision alert symbol will flash on the
windshield. Either eight beeps will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. See
“Collision/Detection
Systems” underVehicle Personalization
0 130.
See Defensive Driving 0217.
Approaching and Following a
Vehicle
The vehicle ahead indicator is in the
instrument cluster and HUD display
(if equipped). It 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 a detected vehicle ahead at the
selected follow gap. The vehicle speed
increases or decreases to follow a
detected vehicle in front of your
vehicle when that vehicle is traveling
slower than your vehicle 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.
Passing a Vehicle While Using ACC
If the set speed is high enough, and
the left turn signal is used to pass a
vehicle ahead in the selected following
gap, ACC may assist by gradually
accelerating the vehicle prior to the
lane change.

258 DRIVING AND OPERATING
{Warning
When using ACC to pass a vehicle
or perform a lane change, the
following distance to the vehicle
being passed may be reduced. ACC
may not apply sufficient
acceleration or braking when
passing a vehicle or performing a
lane change. Always be ready to
manually accelerate or brake to
complete the pass or lane change.
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 (Continued)
Warning (Continued)
caution when using ACC. Your
complete attention is always
required while driving and you
should be ready to take action and
apply the brakes.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles with cargo extending from
the back end.
.Non-standard shaped vehicles, such
as vehicle transport, vehicles with a
side car fitted, or horse carriages.
.Objects that are close to the front of
your vehicle.
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 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.
.A DIC message may display to
indicate that ACC is temporarily
unavailable.
The ACC active symbol will turn white
when ACC is no longer active.
In some cases, when ACC will not
activate, regular cruise control may be
used. See “Switching Between ACC and
Regular Cruise Control ”previously in
this section. Always consider driving
conditions before using either cruise
control system.
Notification to Resume ACC
ACC will maintain a following 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
