Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal and the message TURN SIGNAL ON will
also appear in the
DIC. To turn the chime and message
off, move the turn signal lever td the off position.
Headlamp High/Low-Beam Changer
$0 io (Headlamp High/Low Beam Changer): To
change the headlamps from low
to high beam, push the
lever toward the instrument panel. To return
to
low-beam headlamps, pull the multifunction lever toward
you. Then release
it.
When the high beams are
on, this indicator light on
the instrument panel
cluster will also be on.
I I
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are in the automatic
position. To
use it, pull the turn signal lever toward you, then
release it.
If your headlamps are in the automatic position or on
low beam, your high-beam headlamps will turn on.
They’ll stay on
as long as you hold the lever toward you.
The high-beam indicator
on the instrument panel
cluster will come on. Release the lever
to return to
normal operation.
Windshield Wipers
You control the windshield wipers by turning the band
with the wiper symbol on it.
(Mist): For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go.
The wipers will stop after one wipe.
If you want
more wipes, hold the band on mist longer.
(Delay): You can set the wiper speed for a long or
short delay between wipes. This can be very useful
in light rain or snow. Turn the band to choose the delay
time. The closer
to the top of the lever, the shorter
the delay.
0 (Low Speed): For steady wiping at low speed,
turn the band away from you
to the first solid band past
the delay settings. For high-speed wiping, turn the
band further, to the second solid band past the delay
settings. To stop the wipers, move the band
to off.

Settirn Cruise Cor+poI
If you leave your cruise control on when you’re
not using cruise, you might hit a button and go
into cruise when you don’t want to. You could
be startled and even lose control. Keep the
cruise control switch
off until you want to use
cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The
CRUISE light on the
instrument panel will
illuminate when the cruise
control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
dismgages
the cruise cor;trol. But ~OLI dcn’t need to
reset it.
Once you’re going about
25 mph (40 km/h) or more, you
can move the cruise control switch briefly from on to
resume/accelerate.
You’ll go right back up
to your chosen speed and
stay there.
If you hold the switch at resume/accelerate the vehicle
will keep going faster until you release the switch or
apply the brake.
So unless you want to go faster, don’t
hold the switch at resume/accelerate.

Increasing Speed While Using Cruise
Control

speed. Press the SET button at the end of the lever,
then release the button and the accelerator pedal.
You’ll now cruise at the higher speed.
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch briefly to resume/accelerate.

1 mph (1.6 km/h) faster.
Move the cruise switch from on to
Reducing Speed While Using Cruise
Control
Press in the button at the end of the lever until you
reach the lower speed you want, then release it.
To slow down in very small amounts, briefly press
the set button. Each time you do this, you’ll go
about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot
off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers find this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are four ways to turn off the cruise control:
e Step lightly on the brake pedal,
move the cruise control switch to off, or
shift the transmission to NEUTRAL (N).
If your vehicle has the Stabilitrak@feature, cruise
control will deactivate
if road conditions cause
Stabilitrak@to activate.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.

Exterior Lamps
The control on the driver’s side of your instrument panel
operates the exterior lamps.
The exterior lamp control has four positions:
AUTO: Turn the control to this position to put the
system into automatic headlamp mode. The Daytime
Running Lamps (DRL) will also be activated
if it is light
enough outside.
A light near the symbol will be lit
when in this mode.
0 (Off): Turn the control to this position and release it
to turn
off all exterior lamps including the DRLs. A
light near the symbol will be lit when in this mode.
To turn the lamps back on when in this mode, turn the
switch to the headlamp mode. The
off mode will
cancel when the vehicle is turned
off. This mode is not
available for vehicles first sold in Canada.
:oo: (Parking Lamps): Turn the control to this position
to turn on the parking lamps, together with the
following:
Parking Lamps
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
$0 (Headlamps): Turn the control to this position to
turn
on the headlamps, together with the previously
listed lamps and lights.
When the vehicle is turned
off and the headlamps are in
AUTO, the headlamps may automatically remain on
for a set time. You can change this delay time using the
DIC. See Driver hformation Center
(DIC) on page 3-43.
You can switch your headlamps from low to high-beam
by pushing the turn signaVmultifunction lever toward
the instrument panel.

Automatic Headlamp System
When it is dark enough outside and the headlamp
switch is in AUTO, your automatic headlamp system will
turn on your headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, parking lamps, roof marker lamps and the
instrument panel lights. The radio lights will also be dim.
To turn off the automatic headlamp system, turn the
exterior lamps switch
to the off position and then
release.
Your vehicle has a light sensor located on the top of the
instrument panel. Be sure
it is not covered, or the
system will be on whenever the ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running
Lamps (DRL) and the automatic headlamp systems
so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay. If
you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage,
it will take approximately
one minute for the automatic headlamp system to
change
to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. See ”Instrument
Panel Brightness” under lnterior
Lamps on page 3-76.
Lamps On Reminder
If a door is open, a reminder chime will sound when
your headlamps or parking lamps are manually turned
on and your key is out of the ignition. To turn off
the chime, turn the headlamp switch
to off or AUTO and
then back on. In the automatic mode, the headlamps
turn off once the ignition is in LOCK and the headlamps
on at exit delay ends
(if enabled in the DIC).
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others
to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
first sold in Canada.
