Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, about how much fuel you have and many other things you’ll need to know to drive safely and
economically.

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).
Trip Odometer
The trip odometer can tell you how far your vehicle
has been driven since you last set the trip odometer
to zero.
Press the reset button, located on the instrument panel
cluster next to the trip odometer display, to toggle
between the trip odometer and the regular odometer.
Holding the reset button for two seconds while the
trip odometer is displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.
Engine Hour Meter Display
The odometer can also display the number of hours the
engine has run. To display the hour meter, turn the
ignition off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for
up to 30 seconds, or until the ignition is turned on.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:Do not operate the engine with the
tachometer in the red area, or engine damage may
occur.

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 willflash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
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, seeAir Bag Systems on page 1-55.
This light will come on
when you start your
vehicle, and it willflash 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.

this light will be lit and stay lit to remind you that the air
bag has been turned off. This light will go off when
you turn the air bag back on again. SeeAir Bag
Off Switch on page 1-61for more on this, including
important safety information.The AIR BAG OFF light will

{CAUTION:
If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identied 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
inate 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.

{CAUTION:
If the air bag readiness light 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 inate even though the switch is off. If
this ever happens, don’t let anyone whom the
national government has identied 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) 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.
When the ignition key is turned to RUN or START, the
passenger air bag status indicator will light ON and
OFF, or the symbol for on and off, for several seconds
as a system check. Then, after several more seconds,Passenger Air Bag Status Indicator–United States
Passenger Air Bag Status Indicator–Canada

2003 - Sierra Denali

the status indicator will light either ON or OFF, or either
the on or off symbol to let you know the status of the
right front passenger’s frontal air bag.
If the word ON or the on symbol is lit on the passenger
air bag status indicator, it means that the right front
passenger’s frontal air bag is enabled (may inflate).
{CAUTION:
If the on indicator comes on when you have a
rear-facing child restraint installed in the right
front passenger’s seat, it means that the
passenger sensing system has not turned off
the passenger’s frontal air bag. A child in a
rear-facing child restraint can be seriously
injured or killed if the right front passenger’s
air bag inates. This is because the back of
the rear-facing child restraint would be very
close to the inating air bag. Don’t use a
rear-facing child restraint in the right front
passenger’s seat unless the air bag has been
turned off.If the word OFF or the off symbol is lit on the passenger
air bag status indicator, it means that the passenger
sensing system or the air bag off switch has turned off
the right front passenger’s air bag. SeePassenger
Sensing System on page 1-66orAir Bag Off Switch on
page 1-61for more on this, including important safety
information.
{CAUTION:
If the right front passenger’s air bag is turned
off for a person who isn’t in a risk group
identied 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 inate 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.
