CHEVROLET AVALANCHE 2007 2.G Owners Manual

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
approximately one second while the trip odometer
is displayed will reset it.
To display the odometer reading with the ignition
off, press the reset button.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a
chime will sound for several seconds to remind
people to buckle their safety belts. The driver
safety belt light will also be provided and stay on
for several seconds, then it will ash for several
more. You should buckle your seat belt.
This chime and light
will be repeated if
the driver remains
unbuckled and
the vehicle is
in motion.
If the driver’s belt is buckled, neither the chime
nor the light will come on.
241

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to RUN or
START, a chime will sound for several seconds
to remind the front passenger to buckle their safety
belt. The passenger safety belt light will also
come on and stay on for several seconds, then
it will ash for several more.
This chime and light
will be repeated if the
passenger remains
unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled,
neither the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The
system checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 72.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go out. This means the
system is ready.
242

{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays
on after you start your vehicle.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to
RUN. If the light does not come on then, have
it xed so it will be ready to warn you if there
is a problem.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system.
Your overhead console has a passenger airbag
status indicator.
When the ignition key is turned to RUN or START,
the passenger airbag 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, 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 airbag.
United StatesCanada
243

If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means
that the right front passenger’s frontal airbag is
enabled (may inate).
{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 airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.
{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint,
no system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger
sensing system has turned off the right front
passenger’s frontal airbag. SeePassenger Sensing
System on page 81for more on this, including
important safety information.
244

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.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together,
it means that something may be wrong
with the airbag 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 frontal
airbag. SeeAirbag Readiness Light
on page 242.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, but the engine is
not running, as a check
to show you it is working.
It should go out once the engine is running. If it
stays on, or comes on while you are driving, you
may have a problem with the charging system.
It could indicate that you have problems with the
generator, the generator drive belt, or another
electrical problem. Have it checked right away.
Driving while this light is on could drain your battery.
When this light comes on, the Driver Information
Center (DIC) will also display the SERVICE
BATTERY NOT CHARGING SYSTEM message.
SeeDIC Warnings and Messages on page 267
for more information.
If you must drive a short distance with the light
on, be certain to turn off all your accessories,
such as the radio and air conditioner, to reduce
the drain on your battery.
245

Voltmeter Gage
When your engine
is not running, but the
ignition is in RUN,
this gage shows your
battery’s state of
charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. The charging
system regulates voltage based on the state of
the battery for improved fuel economy and battery
life. The gage may transition from a higher to
lower or a lower to higher reading, this is normal.
Readings between the low and high warning
zones indicate the normal operating range.Readings in the low warning zone may occur
when a large number of electrical accessories are
operating in the vehicle and the engine is left at
an idle for an extended period. This condition
is normal since the charging system is not able
to provide full power at engine idle. As engine
speeds are increased, this condition should
correct itself as higher engine speeds allow the
charging system to create full power. If there is
a problem with the battery charging system,
this light will come on or the SERVICE BATTERY
CHARGING SYSTEM DIC message will display.
SeeDIC Warnings and Messages on page 267
andCharging System Light on page 245for more
information.
Brake System Warning Light
With the ignition on, the brake system warning
light will come on when you set the parking brake.
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).
246

Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not 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 may also come on due to low brake uid.
SeeBrakes on page 472for more information.
This light should come on briey when you
turn the ignition key to RUN. If it does not
come on then, have it xed so it will be ready
to warn you if there is a problem.
{CAUTION:
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 have pulled
off the road and stopped carefully, have
the vehicle towed for service.
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 may go closer
to the oor. It may take longer to stop. If the
light is still on, have the vehicle towed for service.
SeeTowing Your Vehicle on page 408.

Anti-Lock Brake System
Warning Light
With the Anti-Lock Brake
System (ABS), this light
will come on when
you start your engine
and may stay on for
several seconds.
That is normal. If the light does not come on then,
have it xed so it will be ready to warn you if
there is a problem.
If the light stays on, or comes on when you are
driving, your vehicle needs service. A chime
will sound when the light stays on. If the regular
brake system warning light is not on, you still
have brakes, but you do not have ABS.If the regular brake system warning light is
also on you do not have ABS and there is a
problem with your regular brakes. In addition to
both lights, you will also hear a chime sound
on the rst occurrence of a problem and each
time the vehicle is shut off and then restarted.
SeeBrake System Warning Light on page 246.
The ABS warning light should come on briey
when you turn the ignition key to RUN. If the light
does not come on then, have it xed so it will
be ready to warn you if there is a problem.
StabiliTrak®Indicator Light
This warning light
should come on
briey when the
engine is started.
248

If the warning light does not come on then, have
it xed so it will be ready to warn you if there
is a problem. If it stays on, or comes on when
you are driving, there may be a problem with your
StabiliTrak
®system and your vehicle may need
service. When this warning light is on, the system
is off and will not limit wheel spin. Adjust your
driving accordingly.
This light will also ash when the StabiliTrak
®
system is active.
If the StabiliTrak
®system warning light comes on
and stays on for an extended period of time when
the system is turned on, your vehicle needs service.
SeeStabiliTrak
®System on page 359for more
information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your
vehicle is working. During a majority of the
operation, the gage will read 210°F (100°C) or
less. If you are pulling a load or going up hills,
it is normal for the temperature to uctuate
and approach the 250°F (122°C) mark. If the
gage reaches the 260°F (125°C) mark, it indicates
that the cooling system is working beyond
its capacity.
SeeEngine Overheating on page 460.

Tire Pressure Light
This light will come on
briey when you turn
the ignition to RUN.
This light will also come on when one or more
of your tires are signicantly underinated.
If your vehicle has a Driver Information
Center (DIC), a CHECK TIRE PRESSURE
DIC message will accompany the light. See
DIC Warnings and Messages on page 267for
more information.
Stop and check your tires as soon as it is safe
to do so. If underinated, inate to the proper
pressure. SeeTires on page 492for more
information.This light will ash for 60 seconds and then
turn on solid if a problem is detected with the
Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 501
for more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has
a computer which
monitors operation
of the fuel, ignition,
and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels
for the life of the vehicle, helping to produce a
cleaner environment. The check engine light comes
on to indicate that there is a problem and service
is required. Malfunctions often will be indicated
by the system before any problem is apparent.
