The alert symbol will flash when:
.Your vehicle is approaching another vehicle too
quickly.
.Your vehicle is following a vehicle ahead of you
much too closely.
See Defensive Driving
on page 5‑2for more
information.
Detecting the Vehicle Ahead
The vehicle ahead symbol, located next to the FCA
symbol, only appears when a vehicle ahead of you is
detected in your path. If this symbol does not appear,
or disappears briefly, FCA will not respond to vehicles
you may see ahead. The symbol may disappear on
curves, highway exit ramps, or hills. Also, when another
vehicle enters the same lane as you, the FCA system
will not detect the vehicle until it is completely in your
driving lane.
{WARNING:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect a
vehicle ahead. FCA may not help you avoid a
collision under these conditions. Do not use FCA
(Continued)
WARNING: (Continued)
when the radar is blocked by snow, ice, or dirt.
Keep your radar clean. See“Cleaning the
System” underAdaptive Cruise Control

.
{WARNING:
FCA may not detect and warn soon enough to
stationary or slow-moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not rely on FCA when
approaching stationary or slow-moving vehicles or
other objects.
Unnecessary Alerts
FCA may occasionally provide alerts that you consider
unnecessary. It could respond to a turning vehicle
ahead of you, guard rails, signs, and other stationary
objects. This is normal operation, your vehicle does not
need service.

Cruise Control
With cruise control, a speed of approximately 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). A cruise
control light appears in the instrument panel cluster
when the cruise control is on.
When the brakes are applied, the cruise control
shuts off.
{WARNING:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do not
use the 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.If your vehicle is in cruise control when the Traction
Control System (TCS) begins to limit wheel spin, the
cruise control automatically turns off. See
Traction
Control System (TCS)
on page 5‑6. When road
conditions let you safely use it again, the cruise control
can be turned back on.
The cruise control buttons
are located on left side of
the steering wheel.
I(On/Off): Press to turn the cruise control system on
or off.
+ RES (Resume/Accelerate): Press briefly to make the
vehicle resume to a previously set speed or press and
hold to accelerate.

control or make the vehicle decelerate.
[(Cancel): Press to disengage cruise control without
erasing the set speed from memory.
Setting Cruise Control
If the cruise button is on when not in use, it could get
bumped and go into cruise when not desired. Keep the
cruise control switch off when cruise is not being used.
The cruise light on the instrument panel cluster comes
on after the cruise control has been set to the desired
speed.
1. Press
I.
2. Get up to the speed desired.
3. Press the SET– button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brakes are applied, the cruise control is disengaged
without erasing the set speed from memory.
Once the vehicle speed is 40 km/h (25 mph) or greater,
press the +RES button on the steering wheel. The
vehicle returns to the previously set speed and stays
there.
If you press and hold the +RES button, the vehicle
speed increases until the button is released or the
brake is applied. Do not hold in the +RES button, if you
do not want the vehicle speed to increase.
Increasing Speed While Using Cruise
Control
If the cruise control is already activated,
.Press the +RES button. Hold it there until the
desired speed is reached, and then release the
button.
.To increase the vehicle speed in small amounts,
briefly press the +RES button and then release it.
Each time this is done, the vehicle goes about
1.6 km/h (1 mph) faster.

Reducing Speed While Using Cruise
Control
If the cruise control is already activated,
.Press the SET–button until the lower speed
desired is reached, then release it.
.To slow down in small amounts, press the
SET– button briefly. Each time this is done, the
vehicle goes about 1.6 km/h (1 mph) slower.
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 slows down to the previous cruise control
speed.
Using Cruise Control on Hills
How well your cruise control works 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 the vehicle speed.
When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle speed down. When
the brakes are applied or you shift into a lower gear the
cruise control is disengaged.
Ending Cruise Control
There are three ways to end cruise control:
.To disengage cruise control, step lightly on the
brake pedal.
.Press the[button.
.Press theIbutton.
Erasing Speed Memory
The cruise control set speed is erased from memory by
pressing the
Ibutton or if the ignition is turned off.

Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control (ACC) is an enhancement to
traditional cruise control. It allows you to keep cruise
control engaged in moderate traffic conditions without
having to constantly reset your cruise control. ACC
uses radar to detect a vehicle directly ahead in your
path, within a distance of 100 m (330 ft), and operates
at speeds above 40 km/h (25 mph). When it is engaged
by the driver, the system can apply limited braking or
acceleration of the vehicle automatically to maintain a
selected follow distance to the vehicle ahead. Braking is
limited to 2.45 m/sec2 (0.25 g's) of deceleration, which is
comparable to moderate application of the vehicle's
brakes. To disengage ACC, apply the brake. If no
vehicle is in your path, the vehicle will react like
traditional cruise control.
{WARNING:
Adaptive Cruise Control will not apply hard
braking or bring the vehicle to a complete
stop. It will not respond to stopped vehicles,
pedestrians or animals. When you are
approaching a vehicle or object, Adaptive Cruise
Control may not have time to slow your vehicle
enough to avoid a collision. Your complete
attention is always required while driving and you
should be ready to take action and apply the
brakes. For more information, seeDefensive
Driving on page 5‑2.

{WARNING:
.On winding roads, Adaptive Cruise Control
may not detect a vehicle ahead. You could
crash into a vehicle ahead of you. Do not use
Adaptive Cruise Control on winding roads.
.Adaptive Cruise Control may not have time to
slow your vehicle enough to avoid a crash
when you are driving in conditions where
vehicles may suddenly slow or stop ahead of
you, enter your lane, or cross your vehicle's
path. If you are driving in these conditions, do
not use Adaptive Cruise Control. The warning
beep and alert symbol may indicate that you
are driving in conditions where Adaptive
Cruise Control should not be used. See
“Alerting the Driver”in this section.
(Continued)
WARNING: (Continued)
.On slippery roads, fast changes in tire traction
can cause needless wheel spinning, and you
could lose control. Do not use cruise control
on slippery roads.
.When weather limits visibility, such as when in
fog, rain, or snow conditions, Adaptive Cruise
Control performance is limited. There may not
be enough distance to adapt to the changing
traffic conditions. Do not use cruise control
when visibility is low.

There are six follow distances to choose from. The
follow distance selection ranges from near to far
(one second to two seconds follow time). The distance
maintained for a selected follow distance will vary
based on vehicle speed. The faster the vehicle speed
the further back your vehicle will follow. Consider traffic
and weather conditions when selecting the follow
distance. The range of selectable distances may not be
appropriate for all drivers and driving conditions. If you
prefer to travel at a follow distance farther than ACC
allows, disengage the system and drive manually.
Alerting the Driver
The ACC alert symbol is
located on the display at
the top of the instrument
panel to the right of the
driver.
The alert symbol flashes and a warning beep sounds
when driver action may be required. If ACC is engaged,
the alert symbol will flash when:
.ACC cannot apply sufficient braking because you
are approaching a vehicle too rapidly.
.The vehicle speed drops below about 32 km/h
(20 mph).
.A temporary condition prohibits ACC from
operating. See DIC Warnings and Messageson
page 4‑65for more information.
.A malfunction is detected in the system. See DIC
Warnings and Messageson page 4‑65for more
information.
See Defensive Driving on page 5‑2.
{WARNING:
Adaptive Cruise Control has only limited braking
ability to slow your vehicle. In some cases,
Adaptive Cruise Control may not have time to
slow your vehicle enough to avoid a collision. Be
ready to take action and apply the brakes
yourself. See Defensive Driving on page 5‑2.

Approaching and Following a Vehicle
The vehicle ahead symbol
is located on the top of
the instrument panel to
the right of the driver.
The vehicle ahead symbol only appears when a vehicle
is detected in your path.
If this symbol does not appear, or disappears briefly,
ACC will not respond to vehicles you may see ahead.
{WARNING:
When the Adaptive Cruise Control radar is
blocked by snow, ice, or dirt, it may not detect a
vehicle ahead. Adaptive Cruise Control may not
have time to slow your vehicle enough to avoid a
collision. Do not use Adaptive Cruise Control
when the radar is blocked by snow, ice, or dirt.
Keep your radar clean. See “Cleaning the
System” later in this section. ACC automatically slows your vehicle down when
approaching a slower moving vehicle. It then adjusts
your vehicle speed to follow the vehicle in front at the
selected follow distance. Your 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, your brake lights
will come on. Braking may feel or sound different than if
you were applying the brakes yourself. This is normal.
Stationary or Very Slow-Moving Objects
{WARNING:
Adaptive Cruise Control may not detect and react
to stationary or slow‐moving vehicles or other
objects ahead of you. You could crash into an
object ahead of you. Do not use Adaptive
Cruise Control when approaching stationary or
slow‐moving vehicles or other objects.
