small battery, which can be a choking
hazard. If swallowed, internal burns can
occur, resulting in severe injury or death.
Seek medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not touch
metal surfaces on the RKE transmitter
when it has been exposed to extreme
heat. These surfaces can be hot to the
touch at temperatures above 59 °C
(138 °F).
Caution
When replacing the battery, do not touch
any of the circuitry on the transmitter.
Static from your body could damage the
transmitter.
Caution
Always replace the battery with the
correct type. Replacing the battery with
an incorrect type could potentially create
a risk of battery explosion. Dispose of
used batteries according to instructions
and local laws. Do not attempt to burn,
crush, or cut the used battery, and avoid
exposing the battery to environments
with extremely low air pressures or high
temperatures.
Replace the battery in the transmitter soon
if the DIC displays REPLACE BATTERY IN
REMOTE KEY.

R (Reverse), and the front windshield wiper
is performing interval wipes, then the rear
wiper automatically performs interval wipes.
This feature can be turned on or off. See
Vehicle Personalization0110.
The windshield washer reservoir is used for
the windshield and the rear window. Check
the fluid level in the reservoir if either
washer is not working. See Washer Fluid
0 259.
Compass
The vehicle may have a compass display on
the Driver Information Center (DIC). The
compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, StabiliTrak/Electronic
Stability Control (ESC), and vehicle speed
information.
The compass system is designed to operate
for a certain number of miles or degrees of
turn before needing a signal from the GPS
satellites. When the compass display shows
CAL, drive the vehicle for a short distance in
an open area where it can receive a GPS
signal. The compass system will
automatically determine when a GPS signal
is restored and provide a heading again.
Clock
Set the time and date using the
infotainment system. See "Time / Date"
under Settings 0157.
Power Outlets
Power Outlets 12-Volt Direct Current
The vehicle has 12-volt outlets that can be
used to plug in electrical equipment, such as
a cell phone or MP3 player.
{Warning
Power is always supplied to the rear
cargo power outlet. Do not leave
electrical equipment plugged in when the
(Continued)
Warning (Continued)
vehicle is not in use because the vehicle
could catch fire and cause injury or
death.
Caution
Leaving electrical equipment plugged in
for an extended period of time while the
ignition is off will drain the battery.
Always unplug electrical equipment when
not in use and do not plug in equipment
that exceeds the maximum 15 amp
rating.
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 0241.

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
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.
To charge a compatible smartphone:
1. Remove all objects from the charging pad. The system may not charge if there
are any objects on the charging pad.
2. Place the smartphone face up on the charging pad.
To maximize the charge rate, ensure the
smartphone is fully seated and centered
in the holder with nothing under it.
A thick smartphone case may prevent
the wireless charger from working,
or may reduce the charging performance.
See your dealer for additional
information. 3. The
$will appear on theVon the
infotainment display. This indicates that
the smartphone is properly positioned
and charging. If a smartphone is placed
on the charging pad and
$does not
display, remove the smartphone from
the pad, turn it 180 degrees, and wait
three seconds before placing/aligning the
smartphone on the pad again.
