Warning (Continued)
Otherwise the washer fluid
can form ice on the
windshield, blocking your
vision.
{Warning
Before driving the vehicle,
always clear snow and ice
from the hood, windshield,
washer nozzles, roof, and
rear of the vehicle, including
all lamps and windows.
Reduced visibility from snow
and ice buildup could lead to
a crash.
Wiper Parking
If the ignition is turned off
while the wipers are on LO, HI,
or INT with Rainsense
disabled, they will
immediately stop.
If the windshield wiper lever is
then moved to OFF before the
driver door is opened or within 10 minutes, the wipers will
restart and move to the base
of the windshield.
If the ignition is turned off
while the wipers are
performing wipes due to
windshield washing or
Rainsense, the wipers
continue to run until they
reach the base of the
windshield.
Rainsense
If equipped with Rainsense, a
sensor near the top center of
the windshield detects the
amount of water on the
windshield and controls the
frequency of the windshield
wiper.
To turn the Rainsense feature
on or off, select Settings >
Vehicle > Comfort and
Convenience > Rainsense
Wipers > Select ON or OFF.
Keep this area of the
windshield clear of debris to
allow for best system
performance.AUTO :

Instruments and Controls 101
With Rainsense, if the
transmission is in N (Neutral)
and the vehicle speed is very
slow, the wipers will
automatically stop at the base
of the windshield.
The wiper operations return
to normal when the
transmission is no longer in
N (Neutral) or the vehicle
speed has increased.
f:Pull the windshield wiper
lever toward you to spray
windshield washer fluid and
activate the wipers. The
wipers will continue until the
lever is released or the
maximum wash time is
reached. When the windshield
wiper lever is released,
additional wipes may occur
depending on how long the
windshield washer had been
activated. See Washer Fluid
0 393 for information on filling
the windshield washer fluid
reservoir.
Compass
The vehicle has 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
0 207.
Power Outlets
The accessory power outlets
can be used to plug in
electrical equipment, such as a
cell phone or MP3 player.
The vehicle has two accessory
power outlets:
.Inside the center console
storage area.
.On the rear of the center
floor console.
Lift the cover to access the
accessory power outlet.
Certain electrical accessories
may not be compatible with
the accessory power outlet
and could overload a vehicle
circuit breaker or adapter
fuse. If overloaded, the circuit
breaker will reset after all
devices are disconnected or if

Retained Accessory Power
(RAP) is turned off and then
back on. See Retained
Accessory Power (RAP)0267.
Wait one minute to allow the
circuit breaker to reset before
reconnecting devices or
turning RAP back on. If the
problem continues, the issue
could be within your device.
Try another known good
device to make sure the circuit
breaker is operating properly.
If this does not resolve your
problem, see your dealer.
Caution
Failure to replace the circuit
breaker with the minifuse
could overheat the cigar
lighter and damage the
vehicle.
When adding electrical
equipment, be sure to follow
the proper installation
instructions included with the
equipment. See Add-On
Electrical Equipment 0366.
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
If equipped and enabled, the
vehicle has wireless charging
in the bin below the climate
control system. 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 (15 W), as requested by the compatible
smartphone. See Radio

repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.
Some warning lights come on
briefly when the engine is

working. When one of the
warning lights comes on and

there may be a problem, check
the section that explains what
to do. Waiting to do repairs
can be costly and even
