If equipped with Keyless Access,the exterior lamps automatically turnon when a door is opened after theignition is changed to the OFFposition. The dome lamps alsocome on after the ignition ischanged to the OFF position. SeeIgnition Positions (Key Access)0182orIgnition Positions (KeylessAccess)0183.
The exterior lamps turn offimmediately by turning the exteriorlamps control off.
This feature can be changed. SeeVehicle Personalization0127.
Battery Load
Management
The vehicle has Electric PowerManagement (EPM) that estimatesthe battery's temperature and stateof charge. It then adjusts the voltagefor best performance and extendedlife 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. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.
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 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 to
generate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.
Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver.
Battery Power Protection
The battery saver feature isdesigned to protect the vehicle'sbattery.
If some interior lamps are left onand the ignition is turned off, thebattery rundown protection systemautomatically turns the lamp off aftersome time.
Exterior Lighting Battery
Saver
The exterior lamps turn off about10 minutes after the ignition isturned off, if the parking lamps orheadlamps have been manually lefton. This protects against draining

Tire and Loading Information
Label
Label Example
Avehicle-specificTireand
Loading Information label is
attached to the vehicle's center
pillar (B-pillar). The Tire and
Loading Information label shows
the number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.
The Tire and Loading
Information label also shows the
tire size of the original
equipment tires (3) and the
recommended cold tire inflation
pressures (4). For more
information on tires and inflation
seeTires0248andTire
Pressure0256.
There is also important loading
information on the Certification
label. It may show the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front and
rear axle. See“Certification
Label”later in this section.
“Steps for Determining Correct
Load Limit–
1.Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5.Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6.If your vehicle will be towing
atrailer,loadfromyour
trailer will be transferred to

manual to determine how
this reduces the available
cargo and luggage load
capacity of your vehicle.”
This vehicle is neither designed
nor intended to tow a trailer.

Turning the System On and Off
The RPA system can be turned onand off using the infotainmentsystem controls. SeeVehiclePersonalization0127.
When the system is off, PARKASSIST OFF displays on the DriverInformation Center (DIC). Themessage disappears after a shortperiod of time.
RPA defaults to the on setting eachtime the vehicle is started.
Turn off RPA when towing a trailer.
When the System Does Not
Seem to Work Properly
The following messages may bedisplayed on the DIC:
SERVICE PARKING ASSIST :Ifthis message occurs, check thefollowing conditions:
.The sensors are not clean. Keepthe vehicle's rear bumper free ofmud, dirt, snow, ice, and slush.For cleaning instructions, seeExterior Care0280.
.The park assist sensors arecovered by frost or ice. Frost orice can form around and behindthe sensors and may not alwaysbe seen; this can occur afterwashing the vehicle in coldweather. The message may notclear until the frost or ice hasmelted.
If the above conditions do not exist,take the vehicle to your dealer torepair the system.
PA R K A S S I S T O F F :If the RPAsystem does not activate due to atemporary condition, the messagedisplays on the DIC. This can occurunder the following conditions:
.The driver has disabled thesystem.
.An object was hanging out of thetrunk during the last drive cycle.Once the object is removed,RPA will return to normaloperation.
.The bumper is damaged. Takethe vehicle to your dealer torepair the system.

Forward Collision Alert
(FCA) System
If equipped, the FCA system mayhelp to avoid or reduce the harmcaused by front-end crashes. Whenapproaching a vehicle ahead tooquickly, FCA provides a red flashingalert on the windshield and rapidlybeeps.
FCA detects vehicles within adistance of approximately 60 m(197 ft) and operates at speedsabove 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
