Power Outlets
The accessory power outlets can
be used to connect electrical
equipment, such as a cellular
phone.
There are two accessory power
outlets, one is located inside the
center console storage and other on
the rear of the center floor console.
Open the protective cover to use the
accessory power outlet.
Certain electrical accessories
may not be compatible with the
accessory power outlets and could
result in blown vehicle or adapter
fuses. If you experience a problem,
see your dealer/retailer for
additional information on the
accessory power outlet.
Notice:
Adding any electrical
equipment to the vehicle can
damage it or keep other
components from working as
they should. The repairs would
not be covered by the vehicle
warranty. Do not use equipment
exceeding maximum amperage
rating of 20 amperes. Check with
your dealer/retailer before adding
electrical equipment.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment.
Notice:
Improper use of the
power outlet can cause damage
not covered by the vehicle
warranty. Do not hang any type
of accessory or accessory
bracket from the plug because
the power outlets are designed
for accessory power plugs only.
Power Outlet 120 Volt Alternating
Current
The vehicle may have a power
outlet that can be used to plug in
electrical equipment that uses a
maximum limit of 150 watts.
The power outlet is located on the
rear of the center console.
An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is in
ON/RUN and equipment requiring
less than 150 watts is plugged into
the outlet, and no system fault is
detected.

Instruments and Controls
All navigation information is
provided to the HUD by the
navigation radio or OnStar
®
service, for vehicles that have
these features.
The HUD image displayed on the
windshield will automatically dim
and brighten to compensate for
outside lighting. However, the HUD
brightness control can still be
adjusted as needed.
The HUD image can temporarily
light up depending on the angle and
position of the sunlight on the HUD
display. This is normal and will
change when the angle of the
sunlight on the HUD display
changes.
Polarized sunglasses could make
the HUD image harder to see.
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image.
To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
If You Cannot See the HUD
Image When the Ignition Is On
.
Is anything covering the
HUD lens?
.
Is the HUD dimmer setting bright
enough?
.
Is the HUD image adjusted to
the proper height?
.
Are you wearing polarized
sunglasses?
.
Still no HUD image? Check the
fuse in the instrument panel fuse
block. See
Instrument Panel
Fuse Block on page 9
44
.
If the HUD Image Is Not Clear
.
Is the HUD image too bright?
.
Are the windshield and HUD
lens clean?
If the HUD image is not correct,
contact your dealer/retailer.
Keep in mind that the windshield is
part of the HUD system.

Lighting
Turn and Lane-Change
Signals
Move the lever all the way up or
down to signal a turn.
An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it there until the lane
change is completed. If the lever is
briefly pressed and released, the
turn signal flashes three times.
The turn and lane
change signal
can be turned off manually by
moving the lever back to its original
position.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
might be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers
on

.
Fog Lamps
For vehicles with fog lamps, the
button is located on the exterior
lamp control, on the outboard side
of the steering wheel.
To turn on the fog lamps, the ignition
and the headlamps or parking lamps
must be on.
If the fog lamps are turned on while
the exterior lamp switch is in the
AUTO position, the headlamps
come on automatically.
#
:
Press to turn on or off. An
indicator light on the instrument
panel cluster comes on when the
fog lamps are on.
Some localities have laws that
require the headlamps to be on
along with the fog lamps.
Driving and Operating
8-23
Wait at least 15 seconds
between each try, to allow the
cranking motor to cool down.
When the engine starts, let go of
the key or button, and the
accelerator. If the vehicle starts
briefly but then stops again, do
the same thing. This clears the
extra gasoline from the engine.
Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the
oil warms up and lubricates all
moving parts.
Engine Heater
The engine coolant heater,
if available, can help in cold weather
conditions at or below
18°C (0°F)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the
vehicle. An internal thermostat in
the plug-end of the cord will prevent
engine coolant heater operation at
temperatures above
18°C (0°F).
To Use The Engine Coolant
Heater
1.
Turn off the engine.
2.
Open the hood and unwrap the
electrical cord.
The electrical cord is located on
the driver side of the engine
compartment, between the
fender and the engine
compartment fuse block.
3.
Plug it into a normal, grounded
110-volt AC outlet.
{
WARNING
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a fire. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet.
If the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4.
Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine parts.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.

Engine Oil
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the oil
must be warm and the vehicle must
be on level ground.
The engine oil dipstick handle
is a yellow loop. See
Engine
Compartment Overview
on
page 9
6
for the location of the
engine oil dipstick.
1.
Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might not
show the actual level.
2.
Pull out the dipstick and clean it
with a paper towel or cloth, then
push it back in all the way.
Remove it again, keeping the tip
down, and check the level.

Vehicle Care
Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed.
This greatly reduces the chance of
circuit overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
.
Headlamp Wiring
.
Windshield Wiper Motor
.
Power Windows and other
Power Accessories
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.
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.
To identify and check fuses, circuit
breakers, and relays, see

component.
