2008 CHEVROLET COBALT change time

TRIP A or TRIP B
Press the information button until TRIP A or TRIP B
display. These modes show the current distance
traveled since the last reset for each trip odometer in
either miles (mi) or kilometers (km). Both odometers can
be used at the same time.
To reset the trip odometer to zero, press and hold the
reset button for a few seconds while the desired
trip odometer is displayed.
FUEL RANGE
Press the information button until FUEL RANGE
displays. This mode shows the remaining distance you
can drive without refueling in either miles (mi) or
kilometers (km). It is based on fuel economy and the
fuel remaining in the tank.
When the fuel level is low, FUEL RANGE LOW displays.
The fuel economy data used to determine fuel range
is an average of recent driving conditions. As your
driving conditions change, this data is gradually updated.
The FUEL RANGE mode cannot be reset.
MPG (L/100 KM) AVG (Average)
Press the information button until MPG (L/100 KM) AVG
displays. This mode shows how many miles per
gallon (mpg) or liters per 100 kilometers (L/100 km)
your vehicle is getting based on current and past driving
conditions.
To reset the average fuel economy, press and hold the
reset button while MPG (L/100 KM) AVG is displayed.
Average fuel economy is then calculated starting from
that point. If the average fuel economy is not reset, it is
continually updated each time you drive.
MPG (L/100 KM) INST (Instantaneous)
Press the information button until MPG (L/100 KM) INST
displays. This mode shows the current fuel economy
at a particular moment and changes frequently as
driving conditions change. This mode shows the
instantaneous fuel economy in miles per gallon (mpg) or
liters per 100 kilometers (L/100 km). Unlike average
fuel economy, this screen cannot be reset.

CHANGE OIL SOON
This message displays when the life of the engine oil
has expired and it should be changed.
When this message is acknowledged and cleared from
the display, the engine oil life system must still be
reset separately. SeeEngine Oil Life System on
page 5-16andScheduled Maintenance on page 6-4
for more information.
CHECK GAS CAP
This message displays if the fuel cap has not been fully
tightened. Recheck the fuel cap to make sure that it
is on properly. A few driving trips with the cap properly
installed should turn the message off.
CHECK TIRE PRESS (Pressure)
This message displays when the pressure in one or
more of the vehicle’s tires needs to be checked. If a tire
pressure message appears on the DIC, stop as soon
as you can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
SeeTires on page 5-49,Loading Your Vehicle on
page 4-27, andInflation - Tire Pressure on page 5-56.
The DIC also shows the tire pressure values. See
DIC Operation and Displays on page 3-40. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 3-34.

Radio Data System (RDS)
Your radio may have a Radio Data System (RDS).
The RDS feature is available for use only on FM stations
that broadcast RDS information. This system relies
upon receiving specic information from these stations
and only works when the information is available.
While the radio is tuned to an FM-RDS station, the
station name or call letters display. In rare cases, a radio
station can broadcast incorrect information that causes
the radio features to work improperly. If this happens,
contact the radio station.
Playing the Radio
O
(Power/Volume):Press this knob to turn the
system on and off.
Turn this knob clockwise or counterclockwise to increase
or decrease the volume.Speed Compensated Volume (SCV):Radios with
the Speed Compensated Volume (SCV) feature will
automatically adjust the radio volume to compensate for
road and wind noise as the vehicle’s speed changes
while driving, so that the volume level is consistent.
To activate SCV:
1. Set the radio volume to the desired level.
2. Press the MENU button to display the radio
setup menu.
3. Press the pushbutton under the AUTO VOLUM
(automatic volume) label on the radio display.

compensation. The display times out after
approximately 10 seconds. Each higher setting
allows for more radio volume compensation at
faster vehicle speeds.

Braking
SeeBrake System Warning Light on page 3-31.
Braking action involves perception time and reaction
time. First, you have to decide to push on the brake
pedal. That is perception time. Then you have to bring
up your foot and do it. That is reaction time.
Average reaction time is about three-fourths of
a second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of
a second, a vehicle moving at 60 mph (100 km/h) travels
66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between your
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is wet,
dry, or icy; tire tread; the condition of the brakes; the
weight of the vehicle; and the amount of brake force
applied.
Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. The brakes might not have time to cool
between hard stops. The brakes will wear out much fasterif you do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means better
braking and longer brake life.
If your vehicle’s engine ever stops while you are driving,
brake normally but do not pump the brakes. If you do,
the pedal could get harder to push down. If the
engine stops, you will still have some power brake
assist. But you will use it when you brake. Once the
power assist is used up, it can take longer to stop and
the brake pedal will be harder to push.
If your vehicle has Electronic Stability Control (ESC)
and the 2.0L turbocharged engine, it also has a
hydraulic brake boost feature which supplements the
power brake system to maintain consistent brake
performance under conditions of low brake booster
vacuum. Low brake booster vacuum conditions
can include initial start up after the vehicle has been
parked for several hours, very frequent brake stops, or
high altitude driving. When hydraulic brake boost is
active, you might feel minor brake pulsation or
movement but this is normal. If brake pedal feel changes
or the brake pedal feels hard to push, you might not
be receiving the intended brake boost and the SVC
BRAKE SYSTEM DIC message may be displayed.
Adding non-dealer/non-retailer accessories can affect
your vehicle’s performance. SeeAccessories and
Modifications on page 5-3.
