stop start CHEVROLET COBALT 2007 1.G Owner's Manual

When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal
down while you:
Start your engine.
Shift into a gear.
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the
chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when
you are pulling a trailer. SeeScheduled
Maintenance on page 396for more on this.
Things that are especially important in trailer
operation are transaxle uid (do not overll),
engine oil, drive belt, cooling system and brake
system.
Each of these is covered in this manual, and the
Index will help you nd them quickly. If you
are trailering, it is a good idea to review this
information before you start your trip.
Check periodically to see that all hitch nuts and
bolts are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat
during severe operating conditions. SeeEngine
Overheating on page 309.

While refueling, hang the tethered fuel cap from
the hook on the fuel door.
{CAUTION:
Fuel can spray out on you if you open the
fuel cap too quickly. If you spill fuel and
then something ignites it, you could be
badly burned. This spray can happen if
your tank is nearly full, and is more likely
in hot weather. Open the fuel cap slowly
and wait for any hiss noise to stop. Then
unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or overll
the tank and wait a few seconds after you have
nished pumping before removing the nozzle.
Clean fuel from painted surfaces as soon
as possible. SeeWashing Your Vehicle on
page 377.
When replacing the fuel cap, turn it clockwise
until it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the
fuel cap has been left off or improperly installed.This would allow fuel to evaporate into the
atmosphere. SeeMalfunction Indicator Lamp
on page 174.
The CHECK GAS CAP message will be displayed
on the Driver Information Center (DIC) if the fuel
cap is not properly installed. SeeDIC Warnings and
Messages on page 184for more information.
{CAUTION:
If a re starts while you are refueling,
do not remove the nozzle. Shut off the
ow of fuel by shutting off the pump or by
notifying the station attendant. Leave the
area immediately.
Notice:If you need a new fuel cap, be sure
to get the right type. Your dealer/retailer
can get one for you. If you get the wrong type,
it may not t properly. This may cause your
malfunction indicator lamp to light and
may damage your fuel tank and emissions
system. SeeMalfunction Indicator Lamp
on page 174.

{CAUTION:
You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not spill
coolant on a hot engine.
1. You can remove the ll neck pressure cap
when the intercooler system, including the
upper intercooler hose, is no longer hot.
Turn the pressure cap slowly counterclockwise
about one-quarter of a turn. If you hear a
hiss, wait for that to stop. This will allow any
remaining pressure to be vented.
2. Then keep turning the pressure cap slowly,
and remove it.3. Add the proper DEX-COOL
®coolant mixture
to the ll neck, until there is coolant visible in
the horizontal tube section of the ll neck.
4. With the ll neck pressure cap off, start the
engine and let it run for at least 30 seconds.
Watch out for the engine cooling fan. Turn the
engine off. By this time, the coolant level inside
the ll neck may be lower. If the level drops so
that coolant is no longer visible in the horizontal
tube section of the ll neck, add more of the
DEX-COOL
®coolant mixture to the ll neck
until the level is again visible in the horizontal
tube section.
5. Replace the intercooler system pressure cap.
Be sure the pressure cap is hand-tight and
fully seated.
If the coolant is not at the proper level when
the system cools down again, see your dealer.

Brake Adjustment
Every time you make a moderate brake stop, the
disc brakes adjust for wear. If you rarely make
a moderate or heavier stop, then the brakes might
not adjust correctly. If you drive in that way,
then — very carefully — make a few moderate
brake stops about every 1,000 miles (1 600 km),
so the brakes will adjust properly.
If your vehicle has rear drum brakes and the
brake pedal goes down farther than normal,
the rear drum brakes might need adjustment.
Adjust them by backing up and rmly applying
the brakes a few times.
Replacing Brake System Parts
The braking system on a vehicle is complex.
Its many parts have to be of top quality and work
well together if the vehicle is to have really good
braking. Your vehicle was designed and tested with
top-quality brake parts. When you replace parts of
the braking system — for example, when the brake
linings wear down and you need new ones put
in — be sure you get new approved replacement
parts. If you do not, the brakes might not workproperly. For example, if someone puts in
brake linings that are wrong for your vehicle, the
balance between the front and rear brakes can
change — for the worse. The braking performance
you have come to expect can change in many other
ways if someone puts in the wrong replacement
brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery.
Your vehicle’s battery is located in the trunk. You
do not need to access the battery to jump start
your vehicle. SeeJump Starting on page 322.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
