Liftgate
{Warning
Exhaust gases can enter the vehicle if it
is driven with the liftgate or trunk/hatch
open, or with any objects that pass
through the seal between the body and
the trunk/hatch or liftgate. Engine
exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can
cause unconsciousness and even death.
If the vehicle must be driven with the
liftgate or trunk/hatch open:
.Close all of the windows.
.Fully open the air outlets on or under
the instrument panel.
.Adjust the climate control system to a
setting that brings in only outside air
and set the fan speed to the highest
setting. See“Climate Control Systems”
in the Index.
.If the vehicle is equipped with a
power liftgate, disable the power
liftgate function.

Heated Mirrors
If equipped, the heated outside mirrors turn
on when the rear window defogger is on
and help to clear fog or frost from the
surface of the mirrors.
K:This button is on the climate control
panel.
See “Rear Window Defogger” underDual
Automatic Climate Control System 0180.

position when:
.The vehicle is shifted out of R (Reverse),
or remains in R (Reverse) for about
30 seconds.
.The vehicle is turned off.

84 Instruments and Controls
There are power outlets:
.On the center stack below the climate
control system.
.In the rear cargo area.
To use the outlet, remove the cover.
Caution
Leaving electrical equipment plugged in
for an extended period of time while the
vehicle is off will drain the battery.
Always unplug electrical equipment when
not in use and do not plug in equipment
that exceeds the maximum 20 amp
rating.
{Warning
Power is always supplied to the rear
cargo power outlet. Do not leave
electrical equipment plugged in when the
vehicle is not in use because the vehicle
could catch fire and cause injury or
death. Certain accessory plugs may not be
compatible with the accessory power outlet
and could overload vehicle and adapter
fuses. If a problem is experienced, see your
dealer.
When adding electrical equipment, be sure
to follow the proper installation instructions
included with the equipment. See
Add-On
Electrical Equipment 0259.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty. The
power outlets are designed for accessory
power plugs only, such as cell phone
charge cords.
Power Outlet 110/120 Volt Alternating
Current
If equipped, this power outlet can be used
to plug in electrical equipment that uses a
maximum limit of 150 watts.
The power outlet is on the rear of the
center console.
An indicator light on the outlet turns on to
show it is in use. The light comes on when
the ignition is on and equipment requiring
less than 150 watts is plugged into the
outlet, and no system fault is detected.
The indicator light does not come on when
the ignition is off or if the equipment is not
fully seated into the outlet.
If equipment is connected using more than
150 watts or a system fault is detected, a
protection circuit shuts off the power supply
and the indicator light turns off. To reset
the circuit, unplug the item and plug it back
in or turn the Retained Accessory Power

Lighting 129
Exit Lighting
Some exterior lamps and interior lamps turn
on when the driver door is opened after the
vehicle is turned off.
The exterior and interior lamps remain on
for a set amount of time, then automatically
turn off.
The interior lights turn on when the vehicle
is turned off.
The exterior lamps turn off immediately by
turning the exterior lamp control off.
This feature can be changed. On the
infotainment home screen, select the
Settings icon
TVehicleTExit Lighting.
Battery Load Management
The vehicle has Electric Power Management
(EPM) that 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. If the
vehicle has a voltmeter gauge or a voltagedisplay on the Driver Information Center
(DIC), you may see the voltage move 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 of the power
needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, 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 helps prevent the battery from
being drained, if the interior courtesy lamps
or reading lamps are accidentally left on.
If any of these lamps are left on, they
automatically turn off after 10 minutes,
if the ignition is off. The lamps will not
come back on again until one of the
following occurs:
.The ignition is turned on.
.The doors are closed and then re-opened.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
accessory mode.
