2002 GMC SONOMA ESP

1-5 Memory Seat (If Equipped)
If your vehicle has this
feature, the control, located
on the outboard side of the
driver's seat, looks like this.
Use this memory function to save your seat cushion and
seatback settings by using the following procedure:
1. Adjust the driver's seat to a safe and comfortable
driving position.
2. Press the SET button and then press and hold button 1
(for driver) for three seconds. A chime will sound to
let you know that the position has been stored.
A second seating and mirror position can be
programmed by repeating the procedure with a second
driver and pressing button 2 for three seconds. Each
time button 1 or 2 is pressed and released while the
vehicle is in PARK (P), the memory position will be
recalled. Each time a memory button is pressed, a
single chime will sound.3. To program your keyless entry transmitter, if
equipped, press the UNLOCK button within five
seconds of programming the memory button. You
will hear a chime to confirm programming of the
transmitter.
When your vehicle is in PARK (P) for an automatic
transmission or the parking brake is engaged for a
manual transmission, push and release the numbered
memory button you just stored. The seat will move to
the set position. You will hear one chime.
Pressing the UNLOCK button of a keyless entry
transmitter will adjust the seat to the corresponding
stored memory position. You will hear one chime.
Repeat Steps 1 and 2 to readjust the seat. The transmitter
need not be programmed unless it needs to correspond
to the other numbered memory button.
If there is a third driver, use the seat adjuster switch
to adjust the seat. Pressing any of the seat adjuster
switches, the SET button or pressing the desired
memory button twice will cause the seat to stop moving.
If you push the numbered button to adjust the seat and
start the vehicle while the seat is still adjusting,
adjustment will pause while the ignition is in START.
Adjustment will resume after the ignition is in RUN.

or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That's why
safety belts make such good sense.
Here Are Questions Many People Ask
About Safety Belts
-- and the Answers
Q:
Won't I be trapped in the vehicle after an
accident if I'm wearing a safety belt?
A:You could be -- whether you're wearing a safety
belt or not. But you can unbuckle a safety belt,
even if you're upside down. And your chance of
being conscious during and after an accident, so
you can unbuckle and get out, is much greater if
you are belted.
Q:If my vehicle has air bags, why should I have to
wear safety belts?
A:Air bags are in many vehicles today and will be in
most of them in the future. But they are
supplemental systems only; so they work with
safety belts
-- not instead of them. Every air bag
system ever offered for sale has required the use of
safety belts. Even if you're in a vehicle that has air
bags, you still have to buckle up to get the most
protection. That's true not only in frontal collisions,
but especially in side and other collisions.

1-28
When should an air bag inflate?
An air bag is designed to inflate in a moderate to severe
frontal or near
-frontal crash. The air bag will inflate
only if the impact speed is above the system's designed
ªthreshold level.º If your vehicle goes straight into a
wall that doesn't move or deform, the threshold level is
about 9 to 16 mph (14 to 26 km/h). The threshold level
can vary, however, with specific vehicle design, so that
it can be somewhat above or below this range. If your
vehicle strikes something that will move or deform, such
as a parked car, the threshold level will be higher. The
air bag is not designed to inflate in rollovers, rear
impacts, or in many side impacts because inflation
would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined by the angle of the impact and
how quickly the vehicle slows down in frontal or
near
-frontal impacts.
The air bag system is designed to work properly under a
wide range of conditions, including off
-road usage.
Observe safe driving speeds, especially on rough terrain.
As always, wear your safety belt. See ªOff
-Road
Drivingº in the Index for more tips on off
-road driving.What makes an air bag inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. The sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, air bag and related
hardware are all part of the air bag modules inside the
steering wheel and in the instrument panel in front of the
right front passenger.
How does an air bag restrain?
In moderate to severe frontal or near
-frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. Air bags supplement the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant's upper body,
stopping the occupant more gradually. But air bags
would not help you in many types of collisions,
including rollovers, rear impacts and many side impacts,
primarily because an occupant's motion is not toward
those air bags. Air bags should never be regarded as
anything more than a supplement to safety belts,
and then only in moderate to severe frontal or
near
-frontal collisions.

Windows
CAUTION:
Leaving children in a vehicle with the windows
closed is dangerous. A child can be overcome by
the extreme heat and can suffer permanent
injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with the
windows closed in warm or hot weather.

2-7
Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
You can use the keyless entry system, if you have this
feature. You can also use your key to unlock your door
from the outside. To lock your door from the inside,
slide the manual lever on the door down.
To unlock the door, slide
the lever on the door up.
You will see a red area on
the lever.
You can also use the power door lock switch
(if equipped).

3. With the tailgate halfway down, pull the tailgate
toward you at the left side and then move the tailgate
to the left to release the right side.
Reverse the procedure to reinstall the tailgate. Make
sure it is secure.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition. If you have an automatic transmission, taking
your key out also locks your transmission. Also
remember to lock the doors.

2-49 Daytime Running Lamps (If Equipped)
(Optional)
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 lamps are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on at
reduced brightness when the following conditions are met:

The ignition is on,

the exterior lamps control is in OFF,

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.
The following does not apply to vehicles first sold
in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following these steps. When the
system is turned off, the headlamps will not
automatically come on when it becomes dark outside.
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you the
system is off.
3. The system will revert back to the automatic mode
when the DOME OVERRIDE button is again pushed
four times within six seconds (a chime will sound),
or when the ignition is turned off and on again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Playing a Specific Loaded Compact Disc
For every CD loaded, a number will appear on the radio
display. To play a specific CD, first press the CD AUX
button to start playing a CD. Then press the numbered
pushbutton that corresponds to the CD you want to play.
A small bar will appear under the CD number that is
playing, and the track number will appear.
If an error appears on the radio display, see ªCompact
Disc Messagesº later in this section.
LOAD CD
(Eject): The CD eject side of this
button will eject a disc or discs, if you have multiple
discs loaded. To eject a disc or discs from the disc
player, perform one of the following steps:

Press and release the CD eject side of the LOAD CD
button to eject the disc that is currently playing, or

to eject all of the discs, press the CD eject side of the
LOAD CD button for two seconds, you will hear a
beep, and the light will flash to let you know when a
disc is being ejected.When the CD eject side of the LOAD CD button is
pressed, the receiver will eject the disc and REMOVE
CD will be displayed. You can now remove the disc. If
the disc is not removed, after 25 seconds, the disc will
be automatically pulled back into the receiver. If you try
to push the disc back into the receiver, before the
25 second time period is complete, the receiver will
sense an error and will try to eject the disc several times
before stopping.
Do not repeatedly press the CD eject side of the LOAD
CD eject button to eject a disc after you have tried to
push it in manually. The receiver's 25
-second eject
timer will reset at each press of eject, which will cause
the receiver to not eject the disc until the 25
-second time
period has elapsed.
Once the player stops and the disc is ejected, remove
the disc. After removing the disc, press the PWR knob
off and then on again. This will clear the disc
-sensing
feature and enable discs to be loaded into the
player again.
