2004 GMC SONOMA ignition

Sliding Rear Window
If your vehicle has this feature, squeeze the latch in the
center of the window and slide the glass to open it.
When you close the window, be sure the latch is
engaged.
Sun Visors
To block out glare, you can pull the visor down. You
can also swing the visor from side-to-side.
Theft-Deterrent Systems
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.
Content Theft-Deterrent
Your vehicle may be equipped with a Content
Theft-Deterrent alarm system.
With this system, the
SECURITY light will flash
as you open the door
if your ignition is off.
This light reminds you to activate the theft-deterrent
system. Here’s how to do it:
1. Open the door.
2. Lock the door with the power door lock switch or
the remote keyless entry transmitter. The
SECURITY light should come on and stay on.
2-14

3. Close all doors. The SECURITY light should go off
after approximately 30 seconds. The alarm is not
armed until the SECURITY light goes off.
If a door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. Your
vehicle’s headlamps will flash and the horn will sound for
110 seconds, then will turn off to save the battery
power.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
•If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
keyafterthe doors are closed.
•Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door
with the key. You can also turn off the alarm by pressing
UNLOCK on the remote keyless entry transmitter.
The alarm won’t stop if you try to unlock a door any
other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the SECURITY light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
If the alarm does not sound when it should but the
vehicle’s headlamps flash, check to see if the horn
works. The horn fuse may be blown. To replace
the fuse, seeFuses and Circuit Breakers on page 5-95.
If the alarm does not sound or the vehicle’s headlamps
do not flash, the vehicle should be serviced by an
authorized service center.

Passlock®
Your vehicle is equipped with the
Passlock®theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If a correct key is not used or the
ignition lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately five seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before
trying to restart the engine. Remember to release the
key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the SECURITY message
comes on, you will be able to restart the engine if
you turn the engine off. However, your
Passlock
®system is not working properly and must be
serviced by your dealer. Your vehicle is not protected
by Passlock
®at this time. You may also want to check
the fuse. SeeFuses and Circuit Breakers on page 5-95.
See your dealer for service.
In an emergency, call the GM Roadside Assistance
Center. SeeRoadside Assistance Program on page 7-6.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
“break-in.” But it will perform better in the long run
if you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-55for more information.
2-16

Ignition Positions
With the key in the ignition, you can turn it to five
different positions.
Notice:Lengthy operation of features such as
the radio in the accessory ignition position may
drain the battery and prevent your vehicle from
starting. Do not operate your vehicle in the
accessory ignition position for a long period
of time.A (ACCESSORY):This position lets you use things like
the radio and the windshield wipers when the engine
is off. Push in the key and turn it toward you. Your
steering wheel will remain locked, just as it was before
you inserted the key.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the key.
Use the correct key and turn the key only with your
hand. Make sure the key is all the way in. If it is, turn
the steering wheel left and right while you turn the
key hard. If none of this works, then your vehicle
needs service.
B (LOCK):This position locks your ignition when
the key is removed. The steering wheel locks
when equipped with a manual transmission. It’s a
theft-deterrent feature. You will only be able to remove
your key when the ignition is turned to LOCK.
C (OFF):This position lets you turn off the engine
but still turn the steering wheel. Use OFF if you must
have your vehicle in motion while the engine is off
(for example, if your vehicle is being towed).
D (RUN):This is the position for driving.
E (START):This position starts your engine.
2-17

Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features of
your vehicle to continue to work for up to 20 minutes
after the ignition key is turned to OFF.
Your radio, power windows, sunroof and overhead
console will work when the ignition key is in RUN or
ACCESSORY. Once the key is turned from RUN
to OFF, these features will continue to work for up to
20 minutes or until a door is opened.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position–
that’s a safety feature. To restart when you’re already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.Notice:Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it doesn’t start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.
When starting your engine in very cold weather (below
0°F or 18°C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there up to
15 seconds. When the engine starts, let go of
the key.
2. If your engine still won’t start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, do the
same thing, but this time keep the pedal down
for five or six seconds. This clears the extra
gasoline from the engine.

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.
2-20

Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) when the ignition key is in RUN. If you cannot
shift out of PARK (P), ease pressure on the shift
lever–push the shift lever all the way into PARK (P) as
you maintain brake application. Then move the shift
lever into the gear you wish. SeeShifting Out of Park (P)
on page 2-28.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-42.
NEUTRAL (N):In this position, your engine doesn’t
connect with the wheels. To restart when you’re already
moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine racing may damage the
transmission. The repairs would not be covered by
your warranty. Be sure the engine is not racing
when shifting your vehicle.
DRIVE (D):This position is for normal driving. If you
need more power for passing, and you’re:
•Going less than about 35 mph (55 km/h), push your
accelerator pedal about halfway down.
•Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You’ll shift down to the next gear and have more power.
2-21

Transfer Case
The transfer case buttons
are to the right of the
steering wheel on
the instrument panel.
Use these buttons to shift into and out of
four-wheel-drive. You can choose among three driving
settings:
2HI (Two-Wheel Drive High):This setting is for driving
in most street and highway situations. Your front axle
is not engaged in two-wheel drive. When this light
is turned on, it is about one-half as bright as the others.4HI (Four-Wheel Drive High):This setting engages
your front axle to help drive your vehicle. Use 4HI when
you need extra traction, such as on snowy or icy
roads, or in most off-road situations.
4LO (Four-Wheel Drive Low):You may never need
4LO. This setting also engages your front axle to
give you extra traction. It sends the maximum power to
all four wheels. You might choose 4LO if you were
driving off-road in sand, mud or deep snow and climbing
or descending steep hills.
Indicator lights in the buttons show you which setting
you are in. The indicator lights will come on briefly when
you turn on the ignition and one will stay on. If the
lights do not come on, you should take your vehicle in
for service. An indicator light will flash while shifting.
It will remain illuminated when the shift is completed.
Shifting from 2HI to 4HI
Press and release the 4HI button. This can be done at
any speed, and the front axle will lock automatically.
Shifting from 4HI to 2HI
Press and release the 2HI button. This can be done at
any speed, and the front axle will unlock automatically.
