unfolded position.
.The mirrors vibrate at normal
driving speeds.
Fold and unfold the mirrors one time
using the mirror controls to reset
them to their normal position. A noise
may be heard during the resetting of
the power folding mirrors. This sound
is normal after a manual folding
operation.

position when the vehicle is in
R (Reverse). This allows the curb to be
seen when parallel parking. The
mirror(s) may move from their tilted
position when:
.The vehicle is shifted out of
R (Reverse), or remains in
R (Reverse) for about 30 seconds.
.The ignition is turned off.

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.
Always unplug electrical equipment
when not in use and do not plug in
equipment that exceeds the maximum
15 amps rating.
Wireless Charging
The vehicle may have a wireless
charging pad below the climate
controls. The system operates at 145
kHz and wirelessly charges one Qi
compatible smartphone. The power
output of the system is capable of
charging at a rate up to 3 amp (15W),
as requested by the compatible
smartphone. See Radio Frequency
Statement 0410.
{Warning
Wireless charging can affect the
operation of an implanted
pacemaker or other medical devices.
If you have one, it is recommended
to consult with your doctor before
using the wireless charging system.
The vehicle must be on, in ACC/
ACCESSORY, or Retained Accessory
Power (RAP) must be active. The
wireless charging feature may not
correctly indicate charging when the
vehicle is in RAP, or during Bluetooth
phone calls. See Retained Accessory
Power (RAP) 0229.
The operating temperature is −20 °C
(−4 °F) to 60 °C (140 °F) for the
charging system and 0 °C (32 °F) to
35 °C (95 °F) for the smartphone.
A text message may be displayed on
the radio indicating that the system is
unable to charge due to high
temperature while the charger or the
phone is above or below these
operating temperature ranges.
{Warning
Remove all objects from the
charging pad before charging your
compatible smartphone. Objects,
such as coins, keys, rings, paper
clips, or cards, between the
smartphone and charging pad will
become very hot. On the rare
occasion that the charging system
does not detect an object, and the
object gets wedged between the
smartphone and charger, remove
the smartphone and allow the
object to cool before removing it
from the charging pad, to prevent
burns.

138 LIGHTING
If the vehicle has remained parked for
an extended period of time with no
remote key use or Keyless Access
operation, approach detection will be
disabled. To reactivate, press any
button on the remote key or open and
close all vehicle doors to re-enable the
entry lighting feature on approach.
Approach detection will not work if:
.The vehicle battery is low.
.The ignition is on or in ACC/
ACCESSORY.
.Entry lighting is set to Off. See
“Vehicle Locator Lights”under
Vehicle Personalization 0123.
Approach detection will not work with
a single remote key if:
.The remote key is left within a 5 m
(16 ft) range of the vehicle for
several minutes
.The remote key is left inside the
vehicle and all the doors are closed
To help maximize remote key battery
life, do not store the remote key
within 5 m (16 ft) of the vehicle.
Exit Lighting
Some exterior lamps come on at night,
or in areas with limited lighting, when
the driver door is opened after the
ignition is turned off.
The dome lamp comes on after the
ignition is turned off or any door is
opened. The exterior lamps and dome
lamp remain on after the door is
closed for a set amount of time, then
automatically turn off.
The exterior lamps turn off
immediately by turning the exterior
lamp control off.
The exit lighting for exterior lights can
be changed. See Vehicle Personalization
0 123.
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. If the vehicle has a
voltmeter gauge or a voltage display
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 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, 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.
