Turn and Lane-Change Signals
An arrow on the instrument
panel cluster ashes 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 ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times
The lever returns to its starting position when it is
released.
If after signaling a turn or lane change the arrow ashes
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. SeeFuses and Circuit Breakers on
page 5-115.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km),
a warning chime will sound and the TURN SIGNAL ON
message will appear on the Driver Information Center
(DIC) display. See “Turn Signal On” underDIC Warnings
and Messages on page 3-58for more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever
to change the headlamps from low to high beam.
Pull the lever back and then release it to change from
high to low beam.

Headlamps
The exterior lamp control is located towards the end of
the turn signal/multifunction lever.
O(Exterior Lamp Control):Turn the band with this
symbol on it to operate the exterior lamps.
The exterior lamp control has four positions:
O(Off):Turns off all lamps, except the Daytime
Running Lamps (DRL).
AUTO (Automatic):Turns the headlamps on and off
automatically, depending upon how much light is
available outside of the vehicle.
;(Parking Lamps):Turns on the parking lamps
together with the following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
5(Headlamps):Turns on the headlamps, together
with the previously listed lamps and lights.
Wiper Activated Headlamps
This feature activates the headlamps and parking
lamps after the windshield wipers have been in use
for about six seconds. For this feature to work,
the exterior lamp control must be in AUTO.
The wiper-activated headlamps immediately turn off,
when the ignition is turned to LOCK/OFF or the
windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-48for additional
information.
3-17

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Electric Power Management
The vehicle has Electric Power Management (EPM) that
estimates the battery’s temperature and state of charge.
It then adjusts the voltage for best performance and
extended life of the battery.
When the battery’s state of charge is low, the voltage is
raised slightly to quickly bring the charge back up. When
the state of charge is high, the voltage is lowered slightly
to prevent overcharging. If the vehicle has a voltmeter
gage or a voltage display on the Driver Information
Center (DIC), you may see the voltage move up or down.
This is normal. If there is a problem, an alert will be
displayed.The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer loads, and
loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands of
some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to the
driver. If so, a Driver Information Center (DIC) message
might be displayed, such as BATTERY SAVER ACTIVE,
BATTERY VOLTAGE LOW, or LOW BATTERY. If this
message is displayed, it is recommended that the driver
reduce the electrical loads as much as possible. SeeDIC
Warnings and Messages on page 3-58.

To replace the passenger compartment air lter:
1. Turn the ignition to ON/RUN with the engine off.
2. Turn on the windshield wipers and turn the
ignition off again when the wipers are straight up
on the windshield.
This allows access to the leaf screen.
The passenger compartment air lter is located
under the screen.
3. Open the hood to access the engine compartment.
SeeHood Release on page 5-12for more
information.
4. Remove the three screws that hold the screen in
place and lift off the screen by lifting and sliding it
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
lter cover.
6. Lift the lter cover off by pulling it straight up.
7. Remove the old lter and insert a new one.
SeeMaintenance Replacement Parts on page 6-16
for the correct part number for the lter.
8. Reverse Steps 1 through 6 to reinstall the cover.Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
may be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
Notice:If the engine is operated with the tachometer
in the shaded warning area, the vehicle could be
damaged, and the damages would not be covered by
the vehicle warranty. Do not operate the engine with
the tachometer in the shaded warning area.The CTS-V tachometer has tracer lights that follow the
movement of the tachometer indicator. The tracer lights
can be turned off in the DIC Vehicle Customization.
SeeDIC Vehicle Customization on page 3-72for more
information.
For the CTS-V, the tracer lights also ash when it is
time to up-shift to avoid the engine speed limit.
SeeAutomatic Transmission Operation on page 2-36
orManual Transmission Operation on page 2-40
for more information.
Engine Speed Limiter
This feature prevents the engine speed from reaching
an unsafe level. If the level is too high, the throttle closes
or limits the fuel supply until the engine speed returns
to a safe level. Throttle operation and fuel supply returns
to normal when engine speed is lowered.
For the CTS-V, the tachometer tracer lights ashes prior
to reaching engine speed limit. The tracer lights also
ash on automatic transmission vehicles while in
the DSC or Tap Shift modes. United States and

Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime sounds for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light comes
on and stays on for
several seconds, then
ashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
safety belt is already buckled, neither the chime nor the
light comes on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a
chime sounds for several seconds to remind the front
passenger to buckle their safety belt. This only occurs
if the passenger airbag is enabled. SeePassenger
Sensing System on page 1-67for more information.
The passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then ashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and chime
may turn on if an object is put on the seat such as a
briefcase, handbag, or grocery bag. To turn off the
warning light and/or chime, remove the object from the
seat or buckle the safety belt.

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing
and diagnostic module. For more information on the
airbag system, seeAirbag System on page 1-58.
The airbag readiness light
ashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
xed immediately.{CAUTION:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inate in a crash, or they could even inate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 3-58
