Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals
Headlamps
Headlamp High/Low Beam-Changer
Flash-To-Pass Feature
Fog Lamps
Cruise Control (CTS)
For more information on the exterior lamps, seeExterior
Lamps on page 3-24.
Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or
down. The lever returns automatically when the
turn is complete.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete. The lever returns to its original
position when it’s released.
Arrows that ash rapidly when signaling for a turn or
lane change may be caused by a burned-out signal bulb.
Other driver’s won’t see the signal. CTS

Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if
the arrow fails to work when signaling a turn. SeeFuses
and Circuit Breakers on page 5-100.
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 Message”
underDIC Warnings and Messages on page 3-70.
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.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.
Flash-To-Pass Feature
This feature allows you to use the high-beam headlamps
to signal the driver in front of you that you want to pass.
Pull and hold the turn signal/multifunction lever toward
you to use this feature. When you do, the following
will occur:
If the headlamps are either off, in low-beam or in
Daytime Running Lamps (DRL) mode, the
high-beam headlamps will turn on. They’ll stay on
as long as you hold the lever there. Release
the lever to turn them off.
If the headlamps are in high-beam mode, they will
switch to low beam. To return to high-beam, push
the lever away from you.
3-11

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.
When the exterior lamp control is off or in the parking
lamp position and the windshield wiper control is in any
position except off, the Headlamps Suggested
message will appear on the DIC display. See
“Headlamps Suggested Message” underDIC Warnings
and Messages on page 3-70.
When the ignition is turned to OFF, the wiper-activated
headlamps will immediately turn off. They will also
turn off if 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.
Fog Lamps
Use the fog lamps for better vision in foggy or
misty conditions.
The fog lamp control is located on the turn
signal/multifunction lever.
-:The band with/or next to this symbol is used to
turn the fog lamps on and off.
The parking lamps must be on for the fog lamps to work.
To operate the fog lamps on the CTS:
To turn the fog lamps on, turn the fog lamp band on
the lever up to the dot and release it. The band will
return to its original position.
To turn the fog lamps off, turn the fog lamp band up
to the dot and release it. The band will return to its
original position, and the fog lamps will turn off. If you
turn on the high-beam headlamps, the fog lamps will
also turn off. They’ll turn back on again when you
switch back to low-beam headlamps.
To operate the fog lamps on the CTS-V:
To turn the fog lamps on, turn the band on the lever
up to the fog lamp symbol and release it. The band
will return to its original position.
To turn the fog lamps off, turn the band up to the fog
lamp symbol and release it. The band will return to its
original position, and the fog lamps will turn off. If you
turn on the high-beam headlamps, the fog lamps will
also turn off. They’ll turn back on again when you
switch back to low-beam headlamps.

Cruise Control Light
This light comes on
whenever you set your
cruise control.
The light will go out when the cruise control is
turned off. SeeCruise Control on page 3-23for
more information.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
See “Headlamp High/Low-Beam Changer” under
Turn Signal/Multifunction Lever on page 3-10for
more information.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition
is in ON.
If the fuel supply gets low, the Fuel Level Low message
will appear on the DIC and a single chime will sound.
SeeDIC Warnings and Messages on page 3-70
for more information.

You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a wet
road, you cannot stop, accelerate, or turn as well
because your tire-to-road traction is not as good as on
dry roads. And, if your tires do not have much tread
left, you will get even less traction. It is always wise to
go slower and be cautious if rain starts to fall while
you are driving. The surface may get wet suddenly when
your reexes are tuned for driving on dry pavement.

Bulb Replacement
For the proper type of replacement bulb, see
Replacement Bulbs on page 5-56.
For any bulb changing procedure not listed in this
section, contact your dealer.
High Intensity Discharge (HID)
Lighting
{CAUTION:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you
try to service any of the system components,
you could be seriously injured. Have your
dealer or a qualied technician service them.
Your vehicle may have HID headlamps. After your
vehicle’s HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.
Halogen Bulbs
{CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
Headlamps
It is recommended that this component be replaced as
a unit. See your dealer.
