2002 GMC SONOMA reset

2-44 Windshield Washer
There is a paddle marked with the windshield washer
symbol on the top of the multifunction lever. To spray
washer fluid on the windshield, push the paddle. The
wipers will clear the window and then either stop or
return to your preset speed.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
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.

2-46
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 briefly 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 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, briefly 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 briefly. 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.

2-68 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has been
driven, in either miles (used in the United States) or
kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Simply press the trip odometer button.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then it must be. But if
it can't, then it's set at zero, and a label must be put on
the driver's door to show the old mileage reading when
the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
To view the trip odometer, press the button near the
readout. To reset the trip odometer, hold the button until
it clears.
Tachometer (If Equipped)
The tachometer displays the engine speed in revolutions
per minute (rpm).
NOTICE:
On vehicles with a manual transmission, if you
operate the engine with the tachometer in the
shaded area, your engine or other parts could be
damaged. Damage to your engine or vehicle
caused by operating the engine in the shaded
area isn't covered by your vehicle warranty.

Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to set
the variance for your particular location:
1. Find your location on the zone map earlier in this
section. Record your zone number.
2. Press and hold both the MODE and the US/MET
buttons in the COMP/TEMP mode.
3. After five seconds, the compass will acknowledge
the variation mode by displaying the current zone
number. When it does, release both buttons.
4. Press US/MET until your zone number appears on
the display.
5. Press MODE to enter your zone number. Your
variance is now set and the display will return to the
COMP/TEMP mode.TRIP: Once in the TRIP mode, pressing the
MODE button will step you through the following
TRIP functions:

AVG ECON (Average Economy): The average fuel
economy since the last reset is displayed.

INST ECON (Instantaneous Economy):
Instantaneous fuel economy for the last second of
driving is displayed.

RANGE: The display indicates the estimated
distance that can be travelled with the remaining fuel
in the tank, based on the fuel economy for the last
few hours of driving.

FUEL USED: The fuel used since the last reset is
displayed.

AVG SPEED (Average Speed): The average speed
since the last reset is displayed.
To reset the trip computer, press the MODE and
US/MET buttons simultaneously for at least two
seconds. All functions will be displayed briefly once the
system is reset. Reset can only be performed in the AVG
ECON, FUEL USED and AVG SPEED modes. All three
modes are reset simultaneously.
