service GMC SIERRA DENALI 2003 User Guide

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
key after the 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 the system
has been armed.
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 or
by placing the key in the ignition and turning it to
START.
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 message
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 and the headlamps do not
flash, you may have the feature turned
off. See DIC
Operation and Displays on page 3-43 for more
information.
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.
If the engine stalls and the security light flashes,
wait 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 is running and the security light 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 (see
Fuses and Circuit Breakers on page 5-95.) See your
dealer for service.
In an emergency, call the GM Roadside Assistance
Center. See
Roadside Assistance Program on page 7-5
under Customer Assistance Information.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notices Your vehicle doesn’t 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 first
500 miles (805 km).
Don’t drive at any one speed - fast or slow - for
the first
500 miles (805 km). Don’t make
full-throttle starts.
Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new brake
linings aren’t 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.
Don’t tow a trailer during break-in. See “Towing a
Trailer” in the Index for more information.
Ignition Positions
With your key in the ignition switch you can turn it to
four different positions.
c
A
~~~ ~
Notice: If your key seems stuck in LOCK and you
can’t turn
it, be sure you are using the correct key; if
so, is it all the way in? Turn the key only with
your hand. Using a tool to force
it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel cluster, which shows the air bag symbol.
The system checks the air bag’s electrical system for
malfunctions. The light tells you
if there is an electrical
problem. The system check includes the air bag
sensors, the air bag modules, the passenger sensing
system
(if equipped), the wiring and the crash sensing
and diagnostic module. For more information on the
air bag system, see
Air Bag Systems on page 1-57.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then
the light should go out.
This means the system
is
ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.

If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identified by the national government, that
person won’t have the extra protection of an
air bag.
In a crash, the air bag wouldn’t be able
to inflate and help protect the person sitting
there. Don’t
turn off the passenger’s air bag
unless the person
sitting there is in a risk
group. See
”Air Bag Off Switch” in the Index
for more on this, including important safety
information.

this ever happens, don’t let anyone whom the
national government has identified as a
member of a passenger air bag risk group

example, don’t secure a rear-facing child
restraint
in your vehicle) until you have your
vehicle serviced.
Passenger Air Bag Status Indicator
If your vehicle has the passenger sensing system your
rearview mirror will have a passenger air bag status
indicator.

If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identified by the national government, that
person won’t have the extra protection of an
air bag.
In a crash, the air bag wouldn’t be able
to inflate and help protect the person sitting
there. Don’t turn
off the passenger’s air bag
unless the person sitting there is
in a risk
group. See ”Air Bag
Off Switch” in the Index
for more on this, including important safety information.
If, after several seconds, all status indicator lights
remain on, or
if there are no lights at all, there may be a
problem with the lights or the passenger sensing
system. See your dealer for service. If the air bag
off indicator and the air bag
readiness light ever come on together,
it
means that something may be wrong with the
air bag system.
If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting
in the right front
passenger seat may not have the protection of
the air bag. See ”Air Bag Readiness Light” in
the Index.

You can only drive for a short time with the reading in
either warning zone.
If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
With the ignition on, the brake system warning light will
flash when you set the parking brake. The light will
flash
if the parking brake doesn’t release fully. If you try
to drive with the parking brake engaged, a chime
will sound when the vehicle speed is greater than
3 mph (5 km/h).
Your vehicle’s hydraulic brake system is divided into two
parts.
If one part isn’t working, the other part can still
work and stop you. For good braking, though, you need
both parts working well.
If the warning light comes on and a chime sounds there
could be a brake problem. Have your brake system
inspected right away.

This light should come on briefly when you turn the
ignition key
to RUN. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder
to push. Or, the pedal may go closer to the
floor. It may take longer
to stop. If the light is still on,
have the vehicle towed for service. See Towing
Your Vehicle on page 4-45.

Your brake system may not be working
properly
if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident.
If the light is still
on after you’ve pulled
off the road and stopped
carefully, have the vehicle towed for service.

Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds. That’s
normal.

If the light doesn’t come on then, have it fixed so it will
be ready to warn you
if there is a problem.
If the light stays on, or comes on when you’re driving,
your vehicle needs service.
You will also hear a
chime sound when the light
is on steady. If the regular
brake system warning light isn’t on, you still have
brakes, but you don’t have anti-lock brakes. If the
regular brake system warning light is also on you don’t
have anti-lock brakes and there’s a problem with
your regular brakes.
In addition to both lights, you will
also hear a chime sound on the first occurrence of
a problem and each time the car is shut
off and then
restarted. See
Brake System Warning Light on
page 3-34 earlier in this section.
