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, 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 backin or turn the Retained Accessory Power
(RAP) off and then back on. See
Retained
Accessory Power (RAP) 0217. The power
restarts when equipment using 150 watts or
less is plugged into the outlet and a system
fault is not detected.
The power outlet is not designed for and
may not work properly, if the following are
plugged in:
.Equipment with high initial peak wattage,
such as compressor-driven refrigerators
and electric power tools
.Other equipment requiring an extremely
stable power supply, such as
microcomputer-controlled electric blankets
and touch sensor lamps
.Medical equipment
Wireless Charging
If equipped, the vehicle has wireless
charging in the storage bin at the front of
the floor console. 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 0371.
{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. See Retained Accessory
Power (RAP) 0217.
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.
{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

outside air temperature and helps maintain
the temperature inside the vehicle. Any
cover on the front of the vehicle, could
cause a false reading in the displayed
temperature.

information from these sensors to maintain
comfort settings by adjusting the outlet
temperature, fan speed, and air delivery
mode. The system may also supply cooler
air to the side of the vehicle facing the sun.
The recirculation mode will also be used as
needed to maintain cool outlet
temperatures.

Park Assist
With RPA, and if equipped with FPA, as the
vehicle moves at speeds of less than 8 km/h
(5 mph) the sensors on the bumpers may
detect objects up to 2.5 m (8 ft) behind the
vehicle and 1.2 m (4 ft) in front of the
vehicle within a zone 25 cm (10 in) high off
the ground and below bumper level.
These detection distances may be shorter
during warmer or humid weather.
Blocked sensors will not detect objects and
can also cause false detections. Keep the
sensors clean of mud, dirt, snow, ice, and
slush; and clean sensors after a car wash in
freezing temperatures.
{Warning
The Park Assist system does not detect
children, pedestrians, bicyclists, animals,
or objects below the bumper or that are
too close or too far from the vehicle. It is
(Continued)
Warning (Continued)
not available at speeds greater than
8 km/h (5 mph). To prevent injury, death,
or vehicle damage, even with Park Assist,
always check the area around the vehicle
and check all mirrors before backing.
The instrument cluster may have a Park
Assist display with bars that show “distance
to object” and object location information
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,
or both sides of the Safety Alert Seat will
pulse two times. When an object is very
close (<0.6m (2 ft) in the vehicle rear,
or <0.3m (1 ft) in the vehicle front), five beeps will sound from the rear, or both
sides of the Safety Alert Seat will pulse five
times.
Rear Cross Traffic Alert (RCTA)
If equipped, RCTA shows a red warning
triangle with a left or right pointing arrow
on the infotainment display to warn of
traffic coming from the left or right. This
system detects objects coming from up to
20 m (65 ft) from the left or right side of
the vehicle. When an object is detected,
three beeps sound from the left or right,
depending on the direction of the detected
vehicle.
Use caution while backing up when towing
a trailer, as the RCTA detection zones that
extend out from the back of the vehicle do
not move further back when a trailer is
towed.
Turning the Features On or Off
To turn RPA on or off, pressXon the
center console. The indicator light next to
the button comes on when the features are
on and turns off when the features have
been disabled.
