If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. SeeTraction
Control System (TCS) (CTS) on page 4-8orTraction
Control System (TCS) (CTS-V) on page 4-9and
Stabilitrak
®System on page 4-11. When road conditions
allow you to safely use it again, you may turn the
cruise control back on.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not 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.This light on the instrument
panel cluster will come on
while cruise control is on.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more, you
can move the cruise control switch brie y 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.

This light on the instrument
panel cluster will come on
when cruise control is
set. It will go out when
cruise control is turned off.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This shuts off the
cruise control. But you don’t need to reset it.
Once the vehicle is traveling approximately
25 mph (40 km/h) or more, you can press the
plus (resume/accelerate) button to return to your
desired preset speed. The cruise control light will
be displayed again.
The vehicle will return to and stay at your preset speed.
If you press and hold the plus (resume/accelerate)
button, the vehicle speed will increase until you
release the button or apply the brake. Unless you
want to go faster, do not press and hold the plus
(resume/accelerate) button.
Increasing Speed While Using
Cruise Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button, then release the button
and the accelerator pedal. You will now cruise at
the higher speed.
Press the plus (resume/accelerate) button. Hold it
until you get up to the speed that you want, and
then release the button. To increase your speed
in very small amounts, brie y press the plus
(resume/accelerate) button and then release it.
Each time you do this, your vehicle will speed up
approximately 1 mph (1.6 km/h).
The accelerate feature will only work after you have set
the cruise control speed by pressing the set button.

Exterior Lamps
Headlamps
SeeTurn Signal/Multifunction Lever on page 3-10for
more information on the headlamps.
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
rst sold in Canada.
The DRL system will make the turn signal lamps come
on when the following conditions are met:
It is still daylight and the ignition is in ON or START,
the exterior lamp control is in OFF or AUTO with the
headlamps off, and
an automatic transmission is not in PARK (P) or the
parking brake is not set on a manual transmission.When DRL are on, only your front turn signal lamps will
be on. No other exterior lamps will be on when the
DRL are being used. Your instrument panel won’t be lit
up either.
When the exterior lamp control is in AUTO and it’s dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it’s bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. 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
about 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
lever is in the full bright position. See “Instrument Panel
Brightness” underInterior Lamps on page 3-26.

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, how much fuel you’re using and many of the other things you’ll need to know to drive safely
and economically.

SEEK LOCAL/DISTANT:This feature instructs the
audio system to seek only local radio stations with the
strongest signal or to seek all radio stations with a strong
signal in a large area. Use LOCAL when you are in
urban areas where there are several strong radio station
signals and you want to limit the number of stations to
those with the strongest signals only. Use DISTANT
when you are in rural areas where there are fewer radio
station signals available.
To switch between LOCAL and DISTANT, press the
