Instruments and Controls 5-9
Power Outlets
Accessory power outlets can be
used to plug in electrical equipment,
such as a cell phone, MP3
player, etc.
There are three accessory power
outlets. The power outlets located
below the climate control system,
inside the center console storage
bin, and on the rear of the center
console are powered while the
vehicle is in ON/RUN/START or
ACC/ACCESSORY mode, or until
the driver door is opened with
10 minutes of turning off the vehicle.
On the CTS Wagon there is an
additional accessory power outlet
located near the rear cargo net that
is powered at all times.
Remove the cover to access and
replace when not in use.
Notice:Leaving electrical
equipment plugged in for an
extended period of time while the
vehicle is off will drain the
battery. Always unplug electrical equipment when not in use and
do not plug in equipment that
exceeds the maximum 20 ampere
rating.
Certain electrical accessories may
not be compatible with the
accessory power outlet and could
overload vehicle or adapter fuses.
If a problem is experienced, see
your dealer.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See
Add-On
Electrical Equipment on page 9‑58.
Notice: Hanging heavy
equipment from the power outlet
can cause damage not covered
by the vehicle warranty. The
power outlets are designed for
accessory power plugs only, such
as cell phone charge cords.
Cigarette Lighter
The vehicle may have a cigarette
lighter. To use the lighter, push it in
all the way and let go. When it is
ready, it will pop back out by itself.
Notice: Holding a cigarette lighter
in while it is heating does not let
the lighter back away from the
heating element when it is hot.
Damage from overheating can
occur to the lighter or heating
element, or a fuse could be
blown. Do not hold a cigarette
lighter in while it is heating.

6-4 Lighting
Adaptive Forward
Lighting (AFL)
The Adaptive Forward Lighting
System (AFL) pivots the headlamps
horizontally to provide greater road
illumination while turning. To enable
AFL, set the exterior lamp switch on
the multifunction lever to the AUTO
position. Moving the switch out of
the AUTO position will deactivate
the system. AFL will operate when
the vehicle speed is greater than
3 km/h (2 mph). AFL will not operate
when the transmission is in
R (Reverse). AFL is not immediately
operable after starting the vehicle;
driving a short distance is required
to calibrate the AFL. SeeExterior
Lamp Controls on page 6‑1.
Hazard Warning Flashers
|
Hazard Warning Flasher:
Press this button located on the
instrument panel near the audio
system, to make the front and rear
turn signal lamps flash on and off.
This warns others that you are
having trouble. Press again to turn
the flashers off.
Turn and Lane-Change
Signals
An arrow on the instrument panel
cluster flashes in the direction of the
turn or lane change.
Move the lever all the way up or
down to signal a turn. Raise or lower the lever until the
arrow starts to flash to signal a lane
change. Hold it briefly until the lane
change is complete. The arrow will
automatically flash three times.
The lever returns to its starting
position when it is released.
If after signaling a turn or lane
change the arrow flashes rapidly or
does not come on, a signal bulb
may be burned out.
Have the bulbs replaced. If the bulb
is not burned out, check the fuse.
See
Fuses and Circuit Breakers
on
page 10‑42.
Turn Signal On Chime
If the turn signal is left on for about
1.6 km (1 mile), a warning chime will
sound and the TURN SIGNAL ON
message will appear on the Driver
Information Center (DIC) display.
See “Turn Signal On” underDriver
Information Center (DIC)
on
page 5‑27for more information.

Battery
The battery is in the trunk, behind
the trim panel, on the passenger
side of the vehicle. Refer to the
replacement number shown on the
original battery label when a new
battery is needed.
{DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.After a power loss, such as
disconnecting the battery or
removing the maxi fuses in the
power distribution fuse block, the
following steps must be performed
to calibrate the electronic throttle
control. If this is not done, the
engine will not run properly.
1. Turn the ignition to ON/RUN. Do
not start the engine.
2. Leave the ignition in ON/RUN for at least three minutes so that the
electronic throttle control will
cycle and re-learn its home
position.
3. Turn the ignition to LOCK/OFF.
4. Start and run the engine for at least 30 seconds.
Vehicle Storage
{WARNING
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting
on
page 10‑112
for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
Extended Storage: Remove the
black, negative (−) cable from the
battery or use a battery trickle
charger.

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.

Vehicle Care 10-41
Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and other
Power Accessories
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, 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 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.

10-42 Vehicle Care
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
you can.To identify and check fuses, circuit
breakers, and relays, see
