GMC SONOMA 2000 Owner's Manual

2-38 Cruise Control (If Equipped)
With cruise control, you can
maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not
work at speeds below about
25 mph (40 km/h).
If you have an automatic transmission and you apply
your brakes, the cruise control will shut off.
If you have a manual transmission and you apply your
brakes or push the clutch pedal, the cruise control will
shut off.CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your 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 needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

Setting Cruise Control
CAUTION:
If you leave your cruise control switch 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.Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
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 from ON to
R/A for about a half a second.
You'll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A longer than a half a
second, the vehicle will keep going faster until you
release the switch or apply the brake. You could be
startled and even lose control. So unless you want to
go faster, don't hold the switch at R/A.

2-40
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 button at the end of the lever, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.

Move the cruise switch from ON to R/A. 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 to R/A.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
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, press the
button for less than a half a second. Each time you
do this, you'll go 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 two ways to turn off the cruise control:

Step lightly on the brake pedal or push the clutch
pedal, if you have a manual transmission.

Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

Exterior Lamps
Your parking lamp and headlamp switch is on the
driver's side of your instrument panel.
Turn the knob clockwise to the parking lamps symbol to
manually turn on:

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel LightsTurn the knob clockwise to the master lamps symbol to
turn on all the lamps listed as well as the headlamps.
Turn the knob all the way counterclockwise to turn off
your lamps and put the system in auto headlamp mode.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also dim.
Your vehicle is equipped with a light sensor on the
top of the instrument panel under the radio speaker
grill. 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.

2-42
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder chime will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To turn the chime
off, turn the knob all the way to the left or turn the
instrument panel dimmer down to the fully dimmed
position. In the automatic mode, the headlamps turn
off once the ignition key is in OFF.
Daytime Running Lamps (If Equipped)
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 lights are required on
all vehicles first sold in Canada.The DRL system will make your headlamps come on at
reduced brightness when:

the ignition is on,

the headlamp switch is in automatic headlamp mode,

the light sensor detects daytime light,

an automatic transmission is not in PARK (P), and

the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the regular headlamps.
The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the
DRL off, put the transmission in PARK (P) or set the
parking brake. To idle a manual transmission vehicle
with the DRL off, set the parking brake. The DRL will
stay off until you shift out of PARK (P) or release the
parking brake.

2-43
The following does not apply to vehicles first sold in
Canada, and to some early production vehicles.
When necessary, you may turn off the Automatic

(the chime will sound), or turn the ignition to OFF
and then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp switch is on the instrument panel under
the lamps switch. Press the switch to turn the fog lamps
on. Press the switch again to turn them off. A light will
glow in the switch when the fog lamps are on.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beam headlamps
go off, the fog lamps will come on again.

In this position, the dome lamps will remain on
whether the doors are opened or closed.

2-45
You can use the DOME OVERRIDE button, located
below the parking/headlamp knob, to set the dome
lamps to come on automatically when the doors are
opened, or to remain off. To turn the lamps off, press the
button into the ªinº position. With the button in this
position, the dome lamps will remain off when the doors
are open. To return the lamps to automatic operation,
press the button again and return it to the ªoutº position.

come on when you open the door. This will override the
illuminated entry feature, unless you use your keyless
entry transmitter to unlock the vehicle.
Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box, cargo and underhood lamps if they
are left on for more than 20 minutes when the ignition is
off. This will keep your battery from running down.
