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, the cruise control
system may automatically brake to
slow the vehicle down. 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.

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 for selecting
the cruise control set speed and
following gap. Read this entire section
before using this system. ACC uses a
camera and radar sensors to detect
other vehicles. See Radio Frequency
Statement 0349. The following gap is
the following time (or distance)
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.
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 the
Traction Control System (TCS) or StabiliTrak electronic stability control
system activates while ACC is
engaged, ACC may automatically
disengage. See
Traction Control/
Electronic Stability Control 0196. When
road conditions allow ACC to be safely
used, ACC can be turned back on. ACC
will not engage if the TCS or
StabiliTrak electronic stability control
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.

Press and hold +RES up until the
desired set speed appears on the
display, then release it.
. To increase vehicle speed in small
increments, press +RES up to the
first detent. For each press, the
vehicle goes 1 km/h (1 mph) faster.
. To increase vehicle speed in larger
increments, press +RES up to the
second detent. For each press, the
vehicle speed increases to the next
5 km/h (5 mph) mark on the
speedometer.
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.
Reducing Speed While ACC is at a
Set Speed

.Press and hold SET– down until
the desired lower speed is reached,
then release it.
. To decrease the vehicle speed in
smaller increments, press SET–
down to the first detent. For each
press, the vehicle goes about
1 km/h (1 mph) slower.
. To decrease the vehicle speed in
larger increments, press SET–
down to the second detent. For
each press, the vehicle speed
decreases to the next 5 km/h
(5 mph) mark on the speedometer.
Selecting the Follow Distance Gap
When a slower moving vehicle is
detected ahead within the selected
following gap, ACC will adjust the
vehicle's speed and attempt to
maintain the follow distance gap
selected.
Press
[on the steering wheel to
adjust the following gap. Each press
cycles the gap button through three
settings: Far, Medium, or Near. When pressed, the current gap setting
displays briefly on the instrument
cluster and HUD. The gap setting will
be maintained until it is changed.
Since each gap setting corresponds to
a following time (Far, Medium,
or Near), the following distance will
vary based on vehicle speed. The
faster the vehicle speed, the further
back your vehicle will follow a vehicle
detected ahead. Consider traffic and
weather conditions when selecting the
following gap. The range of selectable
gaps may not be appropriate for all
drivers and driving conditions.
Changing the gap setting
automatically changes the alert timing
sensitivity (Far, Medium, or Near) for
the Forward Collision Alert (FCA)
feature. See
Forward Collision Alert
(FCA) System 0217. Alerting the Driver
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 on the HUD 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 0147.
See Defensive Driving 0174.

206 DRIVING AND OPERATING
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 indicator is not displaying, ACC
will not respond to or brake to
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 lights will
come on. The automatic braking mayfeel 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 electronic stability control
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.
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.

DRIVING AND OPERATING 207
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
0 147.
When the vehicle ahead drives away,
press +RES or 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 0194. To resume ACC
and 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 0146.
{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 will
turn blue on the instrument cluster.
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 (Continued)
