INT :Move the lever up to INT for
intermittent wipes, then turn the
N
band up for more frequent wipes or
down for less frequent wipes.
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.
f: Pull the windshield wiper
lever toward you to spray washer
fluid and activate the wipers. The
wipers will continue until the lever is
released or the maximum wash time
is reached. When the lever is
released, additional wipes may
occur depending on how long the
windshield washer had been
activated. See Washer Fluid0231
for information on filling the
windshield washer fluid reservoir. 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 0236.
Heavy snow or ice can overload the
wiper motor.
{Warning
In freezing weather, do not use
the washer until the windshield is
warmed. 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, 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, 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, the wipers
continue to run until they reach the
base of the windshield.
Compass
The vehicle may have a compass
display on the center stack. The
compass receives its heading and
other information from the Global
Positioning System (GPS) antenna,
Electronic Stability Control, 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

Lighting 127
To turn off the DRL, turn the exterior
lamp control to
O. The DRL will stay
off until the control is toggled again.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps and parking
lamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed. The system may also turn on the
headlamps and parking lamps 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 changes to the
DRL. 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
0129.
When it is bright enough outside,
the headlamps and parking lamps
will turn off or may change to
Daytime Running Lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off. To turn automatic headlamp system
back on, turn the band to
Oagain,
then release it.
If the automatic headlamp system
has the headlamps turned on and
you turn the ignition off, the
headlamps will turn off. When the
driver door is opened the
headlamps and parking lamps will
illuminate for a period of time.
The length of the delayed
illumination period can be changed.
See “Exit Lighting” underVehicle
Personalization 0116.
The regular headlamp system
should be turned on when needed.
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 will
come on. The time it takes for the
lamps to turn on depends on the
wiper speed. When the wipers are
turned off, the lamps turn off. To
disable, move the exterior lamp
control to
Oor;.

Vehicle Care 239
Electrical System
Electrical System
Overload
The vehicle has fuses to protect
against an electrical system
overload.
Fuses protect power devices in the
vehicle.
Replace a bad fuse with a new one
of the identical size and rating.
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 until the motor cools
and will then restart.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
fuses. 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
(Continued)
Danger (Continued)
fuse or circuit breaker can result
in a vehicle fire. You and others
could be seriously injured or
killed.
To check a fuse, look at the
silver-colored band inside the fuse.
If the band is broken or melted,
replace the fuse. Be sure to replace
a bad fuse with a new one of the
identical size and rating.
Fuses of the same amperage can
be temporarily borrowed from
another fuse location, if a fuse goes
out. Replace the fuse as soon as
possible.
Instrument Panel Fuse
Block
The instrument panel fuse block is
behind the glove box. The glove box
can be accessed by unlatching the
door damper and squeezing the
pivot to release the damper ring.
Pull the glove box bin side walls in
