2004 GMC SONOMA display

Automatic Transmission Operation
Your automatic transmission has a shift lever on the
steering column.
There are several different positions for your shift lever.
It features an electronic shift position indicator within
the instrument cluster. This display must be powered
anytime the shift lever is capable of being moved out of
PARK (P). This means that if your key is in OFF, but
not locked, there will be a small current drain on
your battery which could discharge your battery over a
period of time. If you need to leave your key in the
ignition in OFF for an extended period, it is
recommended that you disconnect the battery cable
from the battery to prevent discharging your battery.PARK (P):This position locks your rear wheels. It’s the
best position to use when you start your engine
because your vehicle can’t move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle will not move, even when
you are on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). SeeShifting Into Park (P) on
page 2-26. If you are pulling a trailer, see
Towing a Trailer on page 4-55.

Temperature and Compass Display
The outside air temperature and the compass are
displayed at the front of the overhead console. The
buttons are located to the left of the display.
ON/OFF:Press this button to turn the display on or off.US/MET:Press this button for the temperature to be
displayed in either degrees Farenheit (English) or
Celsius (metric).
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on.
If the outside temperature is 37°F (3°C) or lower when
you turn on the ignition, the word ICE will appear
on the display. This is a warning to the driver that road
conditions may be icy, and that appropriate precautions
should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, when your vehicle is new, the
compass may function erratically. If it does, CAL
(Calibration) will appear on the display. To correct the
calibration, drive in a complete 360° circle three
times and the compass will function normally.

Variance is the different 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. Record your
zone number.
2. Press and hold both the ON/OFF and the US/MET
buttons. The display will go off.3. After five seconds, VAR CAL (Variance Calibration)
will appear on the display. When it does, release
both buttons.
4. Press US/MET until your zone number appears on
the display.
5. Press ON/OFF to enter your zone number. Your
variance is now set.
Sunglasses Storage Compartment
The overhead console has a sunglasses storage
compartment.

Driver Information Center (DIC)
If your vehicle is equipped with a Driver Information
Center (DIC), this system displays the outside air
temperature, compass direction and trip information in
the overhead console.
US/MET (United States/Metric):The US/MET (United
States/metric) button allows you to switch the display
between the English and metric system.
MODE:The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.
COMP/TEMP (Compass/Temperature):The display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is
facing.Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37°F (3°C) or lower, the display will
toggle between the ICE and the current temperature
every eight seconds. This is a warning to the drive that
road conditions may be icy, and that appropriate
precautions should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, if C (Calibration) is displayed,
the compass will need to be calibrated. You may also
place the compass in a noncalibrated mode by pressing
the holding the MODE and US/MET buttons at the
same time while in the COMP/TEMP mode. After about
10 seconds, the compass will display C and you can
release the buttons. Drive the vehicle in a complete
360° circle three times at a speed of less than 5 mph
(8 km/h), and the compass will function normally.
Once the calibration is complete, the display will return
to a compass reading.

Variance is the different 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. 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.

the display.
5. Press MODE to set your zone number. Your
variance is now set and the display will return to the
COMP/TEMP mode.
TRIP:Once in the TRIP mode, press the MODE button
for 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.

Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.
If your vehicle is equipped with a luggage carrier, it may
have side rails and crossrails attached to the roof to
secure cargo. The adjustable tie downs, at both ends of
the crossrails, should be used to secure loads to the
luggage carrier. Use GM accessory racks that are
compatible with your luggage carrier for transporting
sports equipment. These are available through
your dealer.

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 resets.
Tachometer
The tachometer (if equipped) displays the engine speed
in revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
