cruise control GMC SONOMA 2003 Owner's Manual

Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
Turn and Lane-Change Signals
Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
Windshield Wipers
Windshield Washer
Cruise Control (If Equipped)
Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or
down. When the turn isnished, the lever will return
automatically.
An arrow on the
instrument panel cluster
willash in the direction of
the turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts toash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
As you signal a turn or a lane change, if the arrows
don’tash but just stay on, a signal bulb may be burned
out and other drivers won’t see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check the fuse (seeFuses and Circuit Breakers
on page 5-89) and for burned-out bulbs.

Cruise Control
If your vehicle is equipped
with cruise control, it is
located on a band at
the end of your turn
signal/multifunction lever.
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).{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 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 located 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 briey from
ON to R/A (Resume/Accelerate).
You’ll go right back up to your chosen speed and
stay there.If you hold the switch at R/A, 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.
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 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, briey 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 the SET 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 SET
button briey. 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
driversnd 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.
If you have an automatic transmission and you
apply your brakes, the cruise control will shut off.
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
The control on the driver’s side of the instrument panel
operates the exterior lamps.
The exterior lamp control has three positions:
9(Off):Turn the exterior lamps control all the way
counterclockwise to turn off the lamps and put the
system in automatic headlamp mode.

Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear. Do not lubricate accelerator
and cruise control cables.
Transfer Case and Front Axle
(Four-Wheel Drive) Inspection
Every 12 months or at engine oil change intervals,
check front axle and transfer case and add lubricant
when necessary. Auid loss could indicate a problem;
check and have it repaired, if needed. Check vent
hose at transfer case for kinks and proper installation.
More frequent lubrication may be required on
off-road use.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chang, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving
habits or conditions result in frequent braking.
