instrument cluster GMC SIERRA DENALI 2003 Owners Manual

Never put a rear facing child restraint in the right front
passenger seat unless the air bag is
off. Here’s why:
A child in a rear-facing child restraint ca
seriously injured or killed if the right front passenger’s air bag inflates. This is because
the back of the rear-facing child restraint
would be very close to the inflating air bag. Be
sure to turn
off the air bag before using a
rear-facing child restraint
in the right front seat
position. If a forward-facing child restraint
is
suitable for your child, always move the passenger seat as far back as
it will go.
A rear seat is a safer place to secure a forward-facing
child restraint. If you need to secure a forward-facing
child restraint in the right front seat position, see
Where
to Put the Restraint
on page 1-38
If the air bag readiness light in the instrument
panel cluster ever comes on when you have
turned
off the air bag, it means that something
may be wrong with the air bag system. The
right front passenger’s air bag could inflate
even though the switch
is off. If this ever
happens, have the vehicle serviced promptly.
Until you have the vehicle serviced, don’t let
anyone whom the national government has identified as a member of a passenger air bag
risk group
sit in the right front passenger’s
position (for example, don’t secure a
rear-facing child restraint
in your vehicle). See
”Air Bag Off Switch’’
in the Index.
In addition to the
AIR BAG OFF switch, your vehicle
may have the passenger sensing system. See
Passenger Sensing System on page 1-68 and
Passenger Air Bag Status Indicator on page 3-30 for
more on this, including important safety information.
1-51

When either the passenger sensing system and/or
the AIR BAG
OFF switch has turned off the
right front passenger’s frontal air bag, the
off
indicator in the passenger air bag status indicator
on the rearview mirror will light and stay lit
when
y-” turn the ignition to RUN or START.
2. Put the restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder
portions
of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
If the air bag readiness light
in the instrument
panel cluster ever comes
on when you have
turned
off the air bag, it means that something
may be wrong with the air bag system. The
right front passenger’s air bag could inflate
even though the switch
is off. If this ever
happens, have the vehicle serviced promptly.
Until
you have the vehicle serviced, don’t let
anyone whom the national government has identified as a member of a passenger air bag
risk group sit in the right front passenger’s
position (for example, don’t secure a
rear-facing child restraint
in your vehicle). See
”Air Bag
Off Switch” in the Index. 4. Buckle the belt. Make sure the release button is
positioned
so you would be able to unbuckle the
safety belt quickly
if you ever had to.

r
There is an air bag
readiness light on the
instrument panel cluster,
which shows the air
bag
symbol.
Where Are the Air Bags?
The system checks the air bag electrical system for
malfunctions. The light tells you
if there is an electrical
problem. See
Air Bag Readiness Light on page 3-27
for more information.
The driver’s air bag is in the middle of the steering
wheel.
1-59

Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment
if your vehicle has the passenger
sensing system.
Stowing of articles under the passenger’s seat or between the passenger’s seat cushion and
seatback may interfere with the proper operation of the passenger sensing system.
I I
If the air bag readiness light in the instrument
panel cluster ever comes on and stays on,
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’s seat may not have the protection
of the frontal air bag. See “Air Bag Readiness
Light”
in the Index for more on this, including
important safety information.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The
cord is located on the driver’s side of the engine
compartment, near the power steering fluid
reservoir. If you have a diesel engine, refer to
diesel supplement for location.
3. Plug it into a normal, grounded 11 0-volt AC outlet.
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a fire. You could
be seriously
injured. Plug the cord into a properly grounded
three-prong
11 0-volt AC outlet. If the cord
won’t reach, use a heavy-duty three-prong
extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug ana
store the cord as it was before to keep it away
from moving engine parts.
If you don’t, it could be
damaged.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead
of trying to list everything here, we ask that you contact
your dealer in the area where you’ll be parking your
vehicle. The dealer can give you the best advice for that
particular area.
Automatic Transmission Operation
Your vehicle is equipped with an automatic transmission
that features an electronic shift position indicator
located within the instrument panel cluster. This display
is powered anytime the shift lever
is capable of being
moved out
of PARK (P). See Fuses and Circuit Breakers
on page
5-95.
There are several different positions for your shift lever.
PARK
(P): This position locks your wheels. It’s the
best position to use when you start your engine because
your vehicle can’t move easily.
2-1 8

Tow/HauI Mode
Your vehicle may be equipped with a tow/haul mode.
The switch is located on the end of the column shift
lever. You can use this feature to assist when towing or
hauling a heavy load.
I
00
When tow/haul is activated
the tow/haul symbol will
illuminate
on the
instrument panel cluster.
See
Tow/Haul Mode under
Towing a Trailer on
page 4-51 for more
information.
All-Wheel Drive
With this feature, engine power is sent to all four wheels
all the time.
This is like four-wheel drive, but there is
no separate
lever or switch to engage or disengage the front axle. It
is fully automatic, and adjusts itself as needed for
road conditions.

Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signai a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return
automatically.
An arrow on the instrument
panel cluster will flash
in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
If you move the lever all the way up or down, and the
arrow flashes at twice the normal rate, a signal bulb may
be burned out and other drivers may not see your
turn signal.
If a bulb
is burned out, replace it to help avoid an
accident. If the arrows don’t
go on at all when you signal
a turn, check for burned-out bulbs or a blown fuse
See
Fuses and Circuit Breakers on page 5-95.
