The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the DRL. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright

Lighting Features
Entry Lighting
Some exterior lamps and the interior lamps
turn on briefly at night, or in areas with
limited lighting, when
Kis pressed on the
Remote Keyless Entry (RKE) transmitter.
When a door is opened, the interior lamps
come on if the dome lamp control is in the
Hposition. After about 30 seconds the
exterior lamps turn off. Entry lighting can be
disabled manually by changing the ignition
out of the OFF position, or by pressing
Q
on the RKE transmitter.
This feature can be changed. See “Vehicle
Locator Lights” underVehicle Personalization
0 98.
Exit Lighting
Some exterior lamps and the interior lamps
come on at night, or in areas with limited
lighting when the key is removed from the
ignition. The exterior and interior lamps
remain on for a set amount of time and
then automatically turn off. The interior
lamps do not come on if the dome lamp
control is in the Off position. The exterior lamps turn off immediately by
turning the exterior lamps control off.
This feature can be changed. See
Vehicle
Personalization 098.
Battery Load Management
The vehicle has Electric Power Management
(EPM), which estimates the battery's
temperature and state of charge. It then
adjusts the voltage for best performance
and extended life of the battery.
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. The
voltmeter gauge or the voltage display on
the Driver Information Center (DIC),
if equipped, may show the voltage moving
up or down. This is normal. If there is a
problem, an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the power that
is needed for very high electrical loads. A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, rear window
defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idle
speed to generate more power, whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a DIC message might be
displayed and it is recommended that the
driver reduce the electrical loads as much as
possible.
Battery Power Protection
This feature shuts off the dome and reading
lamps, if they are left on for more than
10 minutes after the ignition is turned off.

or 4n—or set the parking brake before
placing the transfer case in N (Neutral).
See Shifting Into Park 0189.
Caution
Extended high-speed operation in 4n
may damage or shorten the life of the
drivetrain.
Engagement noise and bump when shifting
between 4
nand 4mor from N (Neutral),
with the engine running, is normal.

Stability Control 0202.
Electronic Transfer Case
Use the transfer case shift knob, next to the
steering wheel, to shift into and out of
four-wheel drive for extra traction.
All of the lights will flash on then off
momentarily when the ignition is turned on.
The light that remains on will indicate the
state of the transfer case.
If the indicator mark on the shift knob does
not match up with the light then that likely
means the knob was moved when the
ignition was off.
The indicator mark on the shift knob must
line up with the indicator light before a shift
can be commanded. To command a shift
rotate the transfer case shift knob to the new desired position. The light will flash
meaning that the shift is in progress. When
the shift is completed the new position will
be illuminated. If the transfer case cannot
complete a shift command, it will go back to
its last chosen setting.
In extreme cold weather it may be
necessary to slow or stop the vehicle to
shift from 2
mto 4m.
Delayed shifts from 4
mto 2mmay be
experienced due to uneven tire wear, low
tire pressure, high vehicle loading, or cold
temperatures.
Caution
Shifting the transmission into gear before
the requested mode indicator light has
stopped flashing could damage the
transfer case.

for RPA. As the 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. When
an object is very close, <0.6 m (2 ft) in the
vehicle rear, continuous beeps will sound

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. 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 40 km/h (25 mph).
{Warning
FCA is a warning system and does not
apply the brakes. When approaching a
slower-moving or stopped vehicle ahead
too rapidly, or when following a vehicle
too closely, FCA may not provide a
warning with enough time to help avoid
a crash. It also may not provide any
warning at all. FCA does not warn of
pedestrians, animals, signs, guardrails,
bridges, construction barrels, or other
objects. Be ready to take action and
apply the brakes. See Defensive Driving
0 170.
FCA can be disabled with either the FCA
steering wheel control or, if equipped,
through vehicle personalization. See
“Collision/Detection Systems” underVehicle
Personalization 098.
Detecting the Vehicle Ahead
FCA warnings will not occur unless the FCA
system detects a vehicle ahead. When a
vehicle is detected, the vehicle ahead
indicator will display green. Vehicles may
not be detected on curves, highway exit
ramps, or hills, due to poor visibility; or if a
vehicle ahead is partially blocked by
pedestrians or other objects. FCA will not
detect another vehicle ahead until it is
completely in the driving lane.
{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.
