CHEVROLET COBALT 2007 1.G Owners Manual

Rear Window Defogger
The rear window defogger uses a warming grid
to remove fog from the rear window.
The rear window defogger will only work when
the ignition is in RUN.
<(Rear):Press the button to turn the rear
window defogger on or off. Be sure to clear as
much snow from the rear window as possible.
An indicator light above the button will come on
to let you know that the rear window defogger
is activated.
The rear window defogger will turn off about
15 minutes after the button is pressed. If turned
on again, the defogger will only run for about
seven minutes before turning off. If the vehicle
is moving faster than 50 mph (80 kph), the
rear defogger will stay on. The defogger can
also be turned off by pressing the button again
or by turning off the engine.Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
Outlet Adjustment
Use the thumbwheels located next to and below
the air outlets to change the direction of the airow
and to open and close the outlets.
Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.

Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment lter. The lter removes certain
particles from the air, including pollen and dust
particles. Reductions in airow, which may occur
more quickly in dusty areas, indicate that the lter
needs to be replaced early.
The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled
Maintenance on page 396for replacement
intervals. See your dealer for details on changing
the lter. To nd out what type of lter to use,
seeNormal Maintenance Replacement Parts
on page 408.To access the passenger compartment air lter
you must go through the glove box.
1. Open the glove box and remove all articles
from the inside.
2. Tilt the glove box door down by squeezing on
each side of the glove box until the door can
be lowered from its track. Lower the glove
box door.
162

3. Open the passenger compartment air lter
door by reaching through the opening in the
back of the glove box and raising the tab until
the door can be opened downward.4. Remove the lter by sliding it out of the
housing.
When installing a new air lter make sure the
AIR FLOW arrow is pointing downward. Reverse
Steps 1 through 5 making sure the glove box
door snaps back into place.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or
is a problem with one of your vehicle’s functions.
As the details show on the next few pages,
some warning lights come on briey when you
start the engine just to let you know they are
working. If you are familiar with this section,
you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions.
Often gages and warning lights work together
to let you know when there is a problem with
your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of
the gages shows there may be a problem, check
the section that tells you what to do about it.
Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning
lights and gages. They can be a big help.
164

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running.
You will know how fast you are going, about how much fuel is left in the tank, and many other things
you will need to drive safely and economically.
United States SS Cluster shown, Canada and Base similar
165

Speedometer and Odometer
Your speedometer lets you see your speed
in both miles per hour (mph) and kilometers
per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip A and
Trip B odometer. See “Trip Information” under
DIC Operation and Displays on page 181.
The odometer mileage can be checked without
the vehicle running. Simply open the driver’s door
and the mileage will be displayed briey.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty.
Do not operate the engine with the tachometer
in the shaded warning area.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will sound for several seconds to remind you and
your passengers to buckle your safety belts.
The driver safety belt light will also come on and
stay on for several seconds, then it will ash for
several more.
You should buckle your
seat belt.
If the vehicle is equipped with the passenger
sensing system, 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. SeePassenger Sensing System
on page 77for more information.
166

Passenger Safety Belt
Reminder Light
If your vehicle has this feature, 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. This would
only occur if the passenger airbag is enabled. See
Passenger Sensing System on page 77for more
information. The passenger safety belt light will also
come on and stay on for several seconds, then it
will ash for several more.
This light and chime
reminder 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 cluster, 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 sensor, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 68.
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.
167

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.
{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.
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
If your vehicle has the passenger sensing system,
then your instrument panel has a passenger
airbag status indicator. SeePassenger Sensing
System on page 77.
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.
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).
United StatesCanada
168

{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 right
front 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 77for more on this,
including important safety information.
169

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 167.
Charging System Light
The charging system
light will come on briey
when you turn on the
ignition, and the engine
is not running, as a
check to show you
it is working.
Then it should go out when the engine is started.
If it stays on, or comes on while you are driving,
you may have a problem with the electrical
charging system. Have it checked by your
dealer/retailer. Driving while this light is on
could drain your battery.
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.
