vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
TCS or StabiliTrak/ESC begins to
limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow. TCS and
StabiliTrak/ESC will automatically
turn on when cruise control is set.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
SeeIf the Vehicle Is Stuck 0187
and “Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin
. Flash when StabiliTrak/ESC is
activated
. Turn on and stay on when either
system is not working
If either system fails to turn on or to
activate, a message may display in
the Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly.
If
dcomes on and stays on:
1. Stop the vehicle. 2. Turn the engine off and wait
15 seconds.
3. Start the engine.
4. Drive the vehicle.
If
dcomes on and stays on, the
vehicle may need more time to
diagnose the problem. If the
condition persists, see your dealer.

212 Driving and Operating
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, the cruise control automatically disengages. See
Traction Control/Electronic Stability
Control
0208. If a collision alert
occurs when cruise control is
activated, cruise control is
disengaged. See Forward Collision
Alert (FCA) System 0229. When
road conditions allow the cruise
control to be safely used, cruise
control can be turned back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage the
cruise control.
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 to that speed or
press and hold to accelerate. If the
cruise control is already active, use
to increase vehicle speed.
SET− :Move the thumbwheel down
briefly to set the speed and activate
cruise control. If the cruise control is
already active, use to decrease
vehicle speed.
*: Press to disengage cruise
control without erasing the set
speed from memory.
Setting Cruise Control
If
Jis on when not in use, SET− or
RES+ could get pressed and go into
cruise when not desired. Keep
J
off when cruise is not being used.

3. Move the thumbwheel down toSET−. The desired set speed
briefly appears in the
instrument cluster.
4. Remove your foot from the accelerator.
When the cruise control has been
set to the desired speed, a green
cruise control indicator appears on
the instrument cluster.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or
*is pressed, the
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, then release it.
. To increase vehicle speed in
small increments, move the
thumbwheel up toward RES+
briefly. For each press, the
vehicle goes about 1 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
and Midlevel) 0124 or
Instrument Cluster (Uplevel) 0128.
The increment value used depends
on the units displayed. Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.
Move the thumbwheel down
toward SET− until the desired
lower speed is reached, then
release it.
. To decrease the vehicle speed in
small increments, move the
thumbwheel down toward SET−
briefly. For each press, the
vehicle goes about 1 km/h
(1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster (Base
and Midlevel) 0124 or
Instrument Cluster (Uplevel) 0128.
The increment value used depends
on the units displayed.

214 Driving and Operating
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 the 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 your
speed. When going downhill, you
might 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).
. Press
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.
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
pedal. 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
0208. When road
conditions allow ACC to be safely
used, the ACC can be turned
back on.
Turning off the TCS or StabiliTrak/
ESC system will disengage the
cruise control.

]
indicator will be lit on the instrument
cluster. When the regular cruise
control is engaged, a green
J
indicator will be lit on the instrument
cluster.
When the vehicle is turned on, the
cruise control mode will be set to
the last mode used before the
vehicle was turned off.
{Warning
Always check the cruise control
indicator on the instrument cluster
to determine which mode cruise
control is in before using the
feature. If ACC is not active, the (Continued)
Warning (Continued)
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 (15 mph), although it
can be resumed when driving at
lower speeds.
To set ACC:
1. Press

3. Move the thumbwheel downtoward 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. When ACC is
active, the indicator will be lit green.
Be mindful of speed limits,
surrounding traffic speeds, and
weather conditions when selecting
the set speed. Resuming a Set Speed
If 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.
.
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.

speed display on the instrument
cluster. The vehicle ahead indicator
may be flashing if a vehicle ahead
was present and moved. See
“Approaching and Following a
Vehicle” later in this section. 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 pedal 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 on the instrument
cluster will turn blue.
. Move the thumbwheel up toward
RES+ until the desired set
speed appears on the display,
then release it.

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 a
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 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 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” under
Vehicle Personalization 0151.
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 0206. To resume
ACC and release the EPB, press
the accelerator pedal.

object gets closer, more bars light
up and the bars change color from
yellow to amber to red.
When an object is first detected in
the rear, one beep will be heard
from the rear, or both sides of the
Safety Alert Seat will pulse two
times. When an object is very close,
<0.6 m (2 ft) in the vehicle rear, five
beeps will sound from the rear,
or both sides of the Safety Alert
Seat will pulse five times.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows a red
warning triangle with a left or right
pointing arrow on the infotainment
display to warn of traffic coming
from the left or right. This system
detects objects coming from up to
20 m (65 ft) from the left or right side
of the vehicle. When an object is
detected, three beeps sound from
the left or right, depending on the
direction of the detected vehicle.
Use caution while backing up when
towing a trailer, as the RCTA
detection zones that extend outfrom the back of the vehicle do not
move further back when a trailer is
towed.
Turning the Features On or Off
To turn RPA on or off, pressXon
the center console. The indicator
light next to the button comes on
when the features are on and turns
off when the features have been
disabled.
RCTA and Rear Park Assist
symbols can be turned on or off
through vehicle personalization. See
“Collision/Detection Systems” under
Vehicle Personalization 0151.
Turn off RPA when towing a trailer.
Assistance Systems for
Driving
If equipped, when driving the
vehicle in a forward gear, Forward
Collision Alert (FCA), Lane
Departure Warning (LDW), Lane
Keep Assist (LKA), Side Blind Zone
Alert (SBZA), Lane Change Alert
(LCA), Forward Automatic Braking
(FAB), and/or the Front Pedestrian Braking (FPB) System can help to
avoid a crash or reduce crash
damage.
Forward Collision Alert
(FCA) System
If equipped, the FCA system may
help to avoid or reduce the harm
caused by front-end crashes. When
approaching a vehicle ahead too
quickly, FCA provides a red flashing
alert on the windshield and rapidly
beeps or pulses the driver seat.
FCA also lights an amber visual
alert if following another vehicle
much too closely.
FCA detects vehicles within a
distance of approximately 60 m
(197 ft) and operates at speeds
above 8 km/h (5 mph). If the vehicle
has Adaptive Cruise Control (ACC),
it can detect vehicles to distances of
approximately 110 m (360 ft) and
operates at speeds above 4km/h
(2.5 mph). See
Adaptive Cruise
Control 0214.
