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.
SeeDefensive Driving on page 5-2for more information.
Detecting the Vehicle Ahead
The vehicle ahead symbol, located next to the FCAsymbol, will only appear when a vehicle ahead of you isdetected in your path. If this symbol does not appear,or disappears briefly, FCA will not respond to vehiclesyou may see ahead. The symbol may disappear oncurves, highway exit ramps, or hills. Also, when anothervehicle enters the same lane as you, the FCA systemwill not detect the vehicle until it is completely inyour 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 when the
radar is blocked by snow, ice, or dirt. Keep your
radar clean. See “Cleaning the System” under
Adaptive Cruise Control on page 4-15.
{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 considerunnecessary. It could respond to a turning vehicleahead of you, guard rails, signs, and other stationaryobjects. This is normal operation, your vehicle does notneed service.
Other Messages
There are three messages that may appear on theDriver Information Center (DIC). They are CLEANRADAR, RADAR CRUISE NOT READY and SERVICERADAR CRUISE. SeeDIC Warnings and Messageson page 4-67.
Cleaning the System

The system operates in the delay mode. If the system isleft on for long periods of time, occasional wipes mayoccur without any moisture on the windshield. Thisis normal and indicates that the Rainsense™systemis active.
The Rainsense™system is activated by turning thewiper control band to one of the five sensitivity levelswithin the delay area. The position closest to off isthe lowest sensitivity setting, level one. This allows morerain or snow to collect on the windshield betweenwipes. Turning the wiper band away from you to highersensitivity levels increases the sensitivity of thesystem and frequency of wipes. The highest sensitivitysetting, level five is closest to low. A single wipe willoccur each time you turn the wiper stalk to a highersensitivity level to indicate that the sensitivity level hasbeen increased.
Notice:Going through an automatic car wash withthe wipers on can damage them. Turn the wipersoff when going through an automatic car wash.
The MIST and wash cycle operates as normal and arenot affected by the Rainsense™function. The systemcan be overridden at any time by manually changing thewiper control to low or high speed.
Notice:Do not place stickers or other items on theexterior glass surface directly in front of the rainsensor.
Windshield Washer
{WARNING:
In freezing weather, do not use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
J(Washer Fluid):Press and release this paddle,
located at the top of the turn signal/multifunction lever, tospray washer fluid on the windshield. The wipers willclear the windshield and either stop or return tothe preset speed. For more washer cycles, press andhold the paddle.

Cruise Control
With cruise control, a speed of approximately 40 km/h(25 mph) or more can be maintained without keepingyour foot on the accelerator. Cruise control does not workat speeds below about 40 km/h (25 mph). A cruise controllight appears in the instrument panel cluster when thecruise control is on.
When the brakes are applied, the cruise controlshuts 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 TractionControl System (TCS) begins to limit wheel spin,the cruise control automatically turns off. SeeTractionControl System (TCS) on page 5-6. When roadconditions let you safely use it again, the cruise controlcan be turned back on.
Setting Cruise Control
{WARNING:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.

application of the vehicle’s brakes. To disengage ACC,apply the brake. If no vehicle is in your path, thevehicle 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, see
Defensive Driving on page 5-2.
{WARNING:
•On winding roads, Adaptive Cruise Control
may not detect a vehicle ahead. You couldcrash into a vehicle ahead of you. Do not useAdaptive Cruise Control on winding roads.
•Adaptive Cruise Control may not have time to
slow your vehicle enough to avoid a crashwhen you are driving in conditions wherevehicles may suddenly slow or stop ahead ofyou, enter your lane, or cross your vehicle’spath. If you are driving in these conditions, donot use Adaptive Cruise Control. The warningbeep and alert symbol may indicate that youare driving in conditions where AdaptiveCruise Control should not be used. See“Alerting the Driver” in this section.
•On slippery roads, fast changes in tire traction
can cause needless wheel spinning, and youcould lose control. Do not use cruise controlon slippery roads.
