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 and the feature
is turned on, 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 based on
the current sensitivity setting.
Keep this area of the windshield clear of
debris to allow for best system performance.

compass receives its heading and other
information from the Global Positioning
System (GPS) antenna, 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

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
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 instrumentpanel brightness control is in the full bright
position. See
Instrument Panel Illumination
Control 0137.
When it is bright enough outside, the
headlamps 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.
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. The transition time

Vehicle Care 333
Replace a bad fuse with a new one of the
identical size and rating.
If there is a problem on the road and a fuse
needs to be replaced, there are some spare
fuses and a fuse puller in the left
instrument panel fuse block. The
same amperage fuse can also be borrowed.
Choose some feature of the vehicle that is
not needed to use and replace it as soon as
possible.
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 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.
{Warning
Installation or use of fuses that do not
meet GM’s original fuse specifications is
dangerous. The fuses could fail, and result
in a fire. You or others could be injured
or killed, and the vehicle could be
damaged.
See Accessories and Modifications 0309 and
General Information 0309.
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.
Engine Compartment Fuse Block
The engine compartment fuse block is in the
engine compartment, on the driver side of
the vehicle.
