Cruise Control
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
When the brakes are applied, the cruise control
turns off.
If the vehicle has the StabiliTrak
®system and begins
to limit wheel spin while you are using cruise control,
the cruise control will automatically disengage.
SeeStabiliTrak
®System on page 4-6. When road
conditions allow you to safely use it again, the cruise
control can be turned back on.The cruise control buttons
are located on the left side
of the steering wheel.
I(On/Off):Press to turn the system on or off.
The indicator light on the button turns on when cruise
control is on.
+ RES (Resume/Accelerate):Press to make the
vehicle accelerate or resume to a previously set speed.
SET−(Set/Coast):Press to set the speed or make
the vehicle decelerate.
[(Cancel):Press to cancel cruise control without
erasing the set speed from memory.CTS Shown, CTS-V

Setting Cruise Control
Cruise control will not work if the parking brake is set, or
if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
comes on after the cruise control has been set to
the desired speed.
{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. Press the
Ibutton.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose the cruise control is set at a desired speed
and then the brake is applied. This shuts off the cruise
control. But it does not need to be reset.
Once the vehicle is driving at about 25 mph (40 km/h)
or more, press the +RES button on the steering
wheel. The vehicle goes back to the previously set
speed and stays there.
Increasing Speed While Using Cruise
Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle goes about 1 mph (1.6 km/h) faster.
3-15

Reducing Speed While Using Cruise
Control
To reduce the vehicle’s speed while using cruise
control:
Press and hold the SET– button on the steering
wheel until the desired speed is reached, then
release it.
To slow down in very small amounts, press the
SET– button on the steering wheel briey.
Each time this is done, the vehicle goes about
1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal, the
vehicle slows down to the previously set cruise speed.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle’s speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift
to a lower gear to keep the vehicle’s speed down.
When the brakes are applied the cruise control turns off.
Ending Cruise Control
There are four ways to end cruise control:
Step lightly on the brake pedal
(manual and automatic transmissions).
Press the clutch pedal to the oor
(manual transmissions).
Press[on the steering wheel.
PressIon the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles rst sold in Canada.
The DRL system will make either the reduced intensity
low-beam headlamps or dedicated DRL’s come on
when the following conditions are met:
It is still daylight and the ignition is in ON/RUN
or START.
The exterior lamp control is in off or AUTO and the
headlamps are off.
The automatic transmission is not in P (Park).
When DRL’s are on, only the reduced intensity
low-beam headlamps or dedicated DRL’s will be on.
The other exterior lamps and the instrument panel
cluster will not be on.When the exterior lamp control is in AUTO and it is dark
enough outside, the DRL turns off and the low-beam
headlamps will turn on. When it is bright enough outside,
the low-beam headlamps will go off, and the DRL will
turn back on. If the vehicle is started in a dark garage,
the automatic headlamp system comes on immediately.
Once the vehicle leaves the garage, it takes about
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
the instrument panel cluster may not be as bright
as usual. Make sure the instrument panel brightness
lever is in the full bright position. SeeInstrument Panel
Brightness on page 3-20.
Turning the exterior lamp control to off or to the
low-beam headlamp position will turn off the DRL.
If the parking lamps or the fog lamps were turned on
instead, the DRL will still turn off.
This will work regardless of gear position and whether
or not the parking brake is set.

Brake System Warning Light
This vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking both
parts need to be working well.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the ignition is
turned to ON/RUN. If it does not come on then, have it
xed so it will be ready to warn if there is a problem.
When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will ash or stay on if the parking brake is not
fully released.If the light stays on after the parking brake is fully
released there is a base brake problem.
For vehicles with the Electric Park Brake (EPB), if the
light continues ashing after the brake is released,
or while driving, there is a problem with the Electric
Parking Brake system.
If the light comes on while driving, pull off the road and
stop carefully. The pedal may be harder to push, or
the pedal may go closer to the oor. The vehicle may
take longer to stop. If the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle
on page 4-26.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United States

For vehicles with the Electric Park Brake (EPB), this
light should come on briey when ignition is turned
to ON/RUN. If it does not come on then, have it xed so
it will be ready to warn if there is a problem.
If this light comes on there is a problem with a system
on the vehicle that is causing the park brake system
to work at a reduced level. The vehicle can still be
driven, but should be taken to a dealer/retailer as soon
as possible.
SeeElectric Parking Brake on page 2-44for more
information.
Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briey when the engine
is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on,
the vehicle does not have antilock brakes and there is a
problem with the regular brakes. SeeBrake System
Warning Light on page 3-39.
For vehicles with a Driver Information Center (DIC),
seeDIC Warnings and Messages on page 3-58for all
