Lighting Features
Entry Lighting
Some exterior lamps and the interiorlamps turn on briefly at night, or in
areas with limited lighting, whenK
is pressed on the Remote KeylessEntry (RKE) transmitter. When adoor is opened, the interior lampscome on if the dome lamp control isin the DOOR position. After about30 seconds the exterior lamps turnoff. Entry lighting can be disabledmanually by changing the ignitionout of the OFF position, or by
pressing the RKE transmitterQ
button.
This feature can be changed. See“Ve h i c l e L o c a t o r L i g h t s”underVehicle Personalization0160.
Exit Lighting
Some exterior lamps and the interiorlamps come on at night, or in areaswith limited lighting when the key isremoved from the ignition. Theexterior and interior lamps remainon for a set amount of time and then
automatically turn off. The interiorlamps do not come on if the domelamp control is in the Off position.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0160.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage
moving up or down. This is normal.If there is a problem, an alert will bedisplayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

For more information about CO,
seeEngine Exhaust0276.
To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See“Rocking the Vehicle to Get ItOut”later in this section.
The Traction Control System (TCS)can often help to free a stuckvehicle. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0295.If TCS cannot free the vehicle, see“Rocking the Vehicle to Get it Out”following.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).

{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approachesanother detected vehicle too rapidly,the red FCA display will flash on thewindshield. Also, eight rapidhigh-pitched beeps will sound fromthe front, or both sides of the SafetyAlert Seat will pulse five times.When this Collision Alert occurs, thebrake system may prepare for driverbraking to occur more rapidly whichcan cause a brief, mild deceleration.Continue to apply the brake pedalas needed. Cruise control may bedisengaged when the Collision Alertoccurs.

marking without using a turn signalin that direction. LDW uses acamera sensor to detect the lanemarkings at speeds of 56 km/h(35 mph) or greater.
{Warning
The LDW system does not steer
the vehicle. The LDW system
may not:
.Provide enough time toavoid a crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice; if they arenot in proper condition; or ifthe sun shines directly intothe camera.
.Detect road edges.
.Detect lanes on winding orhilly roads.
(Continued)
Warning (Continued)
If LDW only detects lane
markings on one side of the road,
it will only warn you when
departing the lane on the side
where it has detected a lane
marking. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LDW in
bad weather conditions.
How the System Works
The LDW camera sensor is on thewindshield ahead of the rearviewmirror.

When LDW is on,@is green if
LDW is available to warn of a lanedeparture. If the vehicle crosses adetected lane marking without using
the turn signal in that direction,@
changes to amber and flashes.Additionally, there will be threebeeps, or the driver seat will pulsethree times on the right or left,depending on the lane departuredirection.
When the System Does Not
Seem to Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.

If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due to tarmarks, shadows, cracks in the road,temporary or construction lanemarkings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.
Lane Keep Assist (LKA)
(1500 Series)
If equipped, LKA may help avoidcrashes due to unintentional lanedepartures. It may assist by gentlyturning the steering wheel if thevehicle approaches a detected lanemarking without using a turn signalin that direction. It may also provideaLaneDepartureWarning(LDW)system alert as the lane marking iscrossed. The LKA system will notassist or provide an LDW alert if itdetects that you are activelysteering. Override LKA by turningthe steering wheel. LKA uses a
camera to detect lane markingsbetween 60 km/h (37 mph) and180 km/h (112 mph).
{Warning
The LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems
may not:
.Provide an alert or enoughsteering assist to avoid alane departure or crash.
.Detect lane markings underpoor weather or visibilityconditions. This can occur ifthe windshield orheadlamps are blocked bydirt, snow, or ice, if they arenot in proper condition, or ifthe sun shines directly intothe camera.
.Detect road edges.
(Continued)
Warning (Continued)
.Detect lanes on winding orhilly roads.
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
alanemarking.EvenwithLKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions.
