90 INSTRUMENTS AND CONTROLS
The wiper-activated headlamps
immediately turn off when the
ignition is turned to off, or the
windshield wiper control is turned off.
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" underSettings0182.
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) 0229.
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.
It is possible to replace the factory
power outlet with a cigar lighter
receptacle, if desired. This requires the
factory installed circuit breaker to be
replaced with a standard minifuse by
the dealer. A minifuse will not reset
and will have to be replace if blown.
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 0307.

Engine Oil
To ensure proper engine performance
and long life, careful attention must
be paid to engine oil. Following these
simple, but important steps will help
protect your investment:
.Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil” in
this section.
.Check the engine oil level regularly
and maintain the proper oil level.
See “Checking Engine Oil” and
“When to Add Engine Oil” in this
section.
.Change the engine oil at the
appropriate time. See Engine Oil Life
System 0318.
.Always dispose of engine oil
properly. See “What to Do with Used
Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially prior
to a long trip. The engine oil dipstick
handle is a loop. See Engine
Compartment Overview 0313 for the
location.
{Warning
The engine oil dipstick handle may
be hot; it could burn you. Use a
towel or glove to touch the dipstick
handle.
If a low oil Driver Information Center
(DIC) message displays, check the oil
level.
Follow these guidelines:
.To get an accurate reading, park the
vehicle on level ground. Check the
engine oil level after the engine has
been off for at least two hours.
Checking the engine oil level on
steep grades or too soon after
engine shutoff can result in incorrect readings. Accuracy
improves when checking a cold
engine prior to starting. Remove the
dipstick and check the level.
.If unable to wait two hours, the
engine must be off for at least
15 minutes if the engine is warm,
or at least 30 minutes if the engine
is not warm. Pull out the dipstick,
wipe it with a clean paper towel or
cloth, then push it back in all the
way. Remove it again, keeping the
tip down, and check the level.

Bulb Replacement
LED Lighting
This vehicle has LED lamps. For
replacement of any LED lighting
assembly, contact your dealer.
Electrical System
Electrical System Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the electrical load is too heavy
a circuit breaker opens, protecting the
circuit until overcurrent condition is
removed. This greatly reduces the
chance of circuit overload and fire
caused by electrical problems.
Fuses and circuit breakers protect
electrical devices in the vehicle.Replace a blown or open 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, the
same amperage fuse can 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. 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.

VEHICLE CARE 335
{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
0 310 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
on the driver side of the engine
compartment.
Lift the fuse block cover to access the
fuses.
The vehicle may not be equipped with
all of the fuses and relays shown.
Caution
Spilling liquid on any electrical
component on the vehicle may
damage it. Always keep the covers
on any electrical component.
