Windshield Wiper/
Washer
With the ignition on or in
accessory mode, move the
windshield wiper lever to
select the wiper speed.
HI : Use for fast wipes.
LO : Use for slow wipes.
INT : Use this setting for
intermittent wipes or for
Rainsense wipes, when
Rainsense is enabled. For
intermittent wipes, move the
lever up to INT, then turn
the
Oband up for more
frequent wipes or down for
less frequent wipes.
If Rainsense is enabled, see
“Rainsense” later in this
section.
If the windshield wipers are in
use while driving, the exterior
lamps come on automatically if
the exterior lamp control is in AUTO. The transition time for
the lamps coming on varies
based on wiper speed. See
“Lights On with Wipers”
under
Automatic Headlamp System
0 148.
OFF : Use to turn the
wipers off.
1X : For a single wipe, briefly
move the wiper lever down.
For several wipes, hold the
wiper lever down.
Clear snow and ice from the
wiper blades and windshield
before using them. If frozen to
the windshield, carefully
loosen or thaw them.
Damaged blades should be
replaced. See Wiper Blade
Replacement 0401.
Heavy snow or ice can
overload the wiper motor.
{Warning
In freezing weather, do not
use the washer until the
windshield is warmed. (Continued)

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 :
When enabled, move
the windshield wiper lever to
AUTO. Turn the
Oband on
the wiper lever to adjust the
sensitivity.
.Turn the band up for more
sensitivity to moisture.
.Turn the band down for less
sensitivity to moisture.
.Move the windshield wiper
lever out of the AUTO
position to deactivate
Rainsense.
Wiper Arm Assembly
Protection
When using an automatic car
wash, move the windshield
wiper lever to OFF. This
disables the automatic
Rainsense windshield wipers.

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

148 Lighting
If equipped, the DRL will come
on when all of the following
conditions are met:
.The ignition is on.
.The exterior lamp control is
in AUTO.
.The light sensor determines
it is daytime.
The DRL turn off when the
headlamps are turned to
Oor
the ignition is off.
For vehicles first sold in
Canada, the DRL can only be
turned off when the vehicle is
parked.
Automatic Headlamp
System
When the exterior lamp
control is set to AUTO and it is
dark enough outside, the
headlamps come on
automatically.
The light sensor is on top of
the instrument panel or on the
windshield near the rearview
mirror. Do not cover the
sensor, otherwise the
headlamps will come on when
they are not needed.
The system may also turn on
the headlamps when driving
through a parking garage or
tunnel.
If the vehicle is started in a
dark garage, the automatic
headlamp system comes on
immediately. If it is light
outside when the vehicle
leaves the garage, there is a slight delay before the
automatic headlamp system
turns off the headlamps.
During that delay, the
instrument cluster may not be
as bright as usual. Make sure
the instrument panel
brightness control is in the full
bright position. See
Instrument Panel Illumination
Control
0150.
When it is bright enough
outside, the headlamps will
turn off.
The automatic headlamp
system turns off when the
exterior lamp control is turned
to
Oor the ignition is off. For
vehicles sold in Canada, this
control only works when the
transmission is in P (Park).
Lights On with Wipers
If the windshield wipers are
activated in daylight with the
engine on, and the exterior
lamp control is in AUTO, the
headlamps, parking lamps, and
other exterior lamps come on.

5. Insert the replacementfuse into the empty slot of
the blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
Headlamp Wiring
An electrical overload may
cause the lamps to go on and
off, or in some cases to remain
off. Have the headlamp wiring
checked right away if the
lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats
due to heavy snow or ice, the
windshield wipers will stop.
Wiper function is available
immediately after the wiper
switch is set to off, and back
to on. To protect the wiper motor
from overheating, the wipers
may slow down when the
windshield is dry for a long
period of time. If a period of
dry operation, or little
moisture, exceeds 10 minutes,
the wipers may switch to
intermittent operation, and
remain there. When moisture
is again detected on the
windshield, wiper operation
will return to the operator
selected speed.
Although the circuit is
protected from electrical
overload, overload due to
heavy snow or ice may cause
wiper linkage damage. Always
clear ice and heavy snow from
the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not
snow or ice, be sure to get it
fixed.
Fuses and Circuit
Breakers
The wiring circuits in the
vehicle are protected from
short circuits by a combination
of fuses and circuit breakers.
This greatly reduces the
chance of damage caused by
electrical problems.
{Danger
Fuses and circuit breakers
are marked with
their ampere rating. Do not
exceed the
specified amperage rating
when replacing fuses and
circuit breakers. Use of an
oversized fuse or circuit
breaker can result in a
vehicle fire. You and others
could be seriously injured or
killed.
