2007 CHEVROLET CORVETTE check engine light

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.
Under certain weather or operating conditions,
occasional brake squeak, squeal, or other
noise might be heard with your vehicle’s
performance braking system. This brake system
is designed for superior fade resistance and
consistent operation using high performance
brake pads. Brake noise is normal and does
not affect system performance.
Adding non-dealer/non-retailer accessories
can affect your vehicle’s performance. See
Accessories and Modications on page 319.Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this
test is going on, and you might even notice that
the brake pedal moves a little. This is normal.
If there is a problem
with ABS, this warning
light will stay on.
SeeAnti-Lock Brake
System Warning
Light on page 197.

You can run the engine to keep warm, but
be careful.
{CAUTION:
Snow can trap exhaust gases under
your vehicle. This can cause deadly
CO (carbon monoxide) gas to get inside.
CO could overcome you and kill you.
You cannot see it or smell it, so you
might not know it is in your vehicle.
Clear away snow from around the base
of your vehicle, especially any that is
blocking the exhaust pipe. And check
around again from time to time to be
sure snow does not collect there.
Open a window just a little on the side of
the vehicle that is away from the wind.
This will help keep CO out.
Run your engine only as long as you must.
This saves fuel. When you run the engine, make it
go a little faster than just idle. That is, push the
accelerator slightly. This uses less fuel for the heat
that you get and it keeps the battery charged.

Section 5 Service and Appearance Care

If you want to do some of your own service
work, you should use the proper service manual.
It tells you much more about how to service
your vehicle than this manual can. To order the
proper service manual, seeService Publications
Ordering Information on page 468.
Your vehicle has an airbag system. Before
attempting to do your own service work,
seeServicing Your Airbag-Equipped Vehicle
on page 64.
You should keep a record with all parts receipts
and list the mileage and the date of any service
work you perform. SeeMaintenance Record
on page 447.
Adding Equipment to the Outside
of Your Vehicle
Things you might add to the outside of your
vehicle can affect the airow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important
part of the proper maintenance of your vehicle.
To help keep the engine clean and maintain
optimum vehicle performance, GM recommends
the use of gasoline advertised as TOP TIER
Detergent Gasoline.
The 8th digit of the Vehicle Identication
Number (VIN) shows the code letter or number
that identies your vehicle’s engine. The VIN is at
the top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 418.
Gasoline Octane
If your vehicle has the 6.0L V8 engine (VIN Code U),
use premium unleaded gasoline with a posted
octane rating of 91 or higher. You may also use
regular unleaded gasoline rated at 87 octane or
higher, but your vehicle’s acceleration may be
slightly reduced, and you may notice a slight
audible knocking noise, commonly referred to as
spark knock. If the octane is less than 87, you may
notice a heavy knocking noise when you drive.
321

If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower for
about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues and you are not
stopped, pull over, stop, and park your vehicle
right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
messages COOLANT OVER TEMPERATURE
and REDUCED ENGINE POWER are displayed,
along with the Check Engine light, an overheat
protection mode which alternates ring groups of
cylinders helps prevent engine damage. In
this mode, you will notice a loss in power and
engine performance. This operating mode allows
your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).
Notice:After driving in the overheated
engine protection operating mode, to avoid
engine damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life
system. SeeEngine Oil on page 333.
