ignition CHEVROLET CORVETTE 2007 6.G Repair Manual

Competitive Driving Mode
The driver can select this optional handling mode
by pressing the ACTIVE HANDLING button on
the console two times within a ve second
time period. COMPETITIVE DRIVING MODE will
be displayed in the DIC. Competitive Driving
Mode allows the driver to have full control of the
rear wheels while the Active Handling System
helps maintain directional control of the vehicle by
selective brake application. This involves less
intervention than with both the Active Handling
System and Traction Control Systems on.
The instrument cluster light will not be on. The
Traction Control System will not be operating.
Adjust your driving accordingly.
When you press the ACTIVE HANDLING button
again, or turn the ignition to Acc., the Active
Handling and Traction Control Systems will
be on. The TRACTION SYSTEM AND ACTIVE
HANDLING-ON message will be displayed
temporarily in the DIC and a chime will be heard.Notice:When traction control is turned off,
or Competitive Driving Mode is active, it
is possible to lose traction. If you attempt to
shift with the rear wheels spinning with a loss
of traction, it is possible to cause damage
to the transmission. Do not attempt to shift
when the rear wheels do not have traction.
Damage caused by misuse of the vehicle
is not covered. See your warranty book for
additional information.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel.
It works like a standard axle most of the time,
but when one of the rear wheels has no traction
and the other does, this feature will allow the
wheel with traction to move the vehicle.

{CAUTION:
Coasting downhill in NEUTRAL (N) or with
the ignition off is dangerous. The brakes
will have to do all the work of slowing
down. They could get so hot that they
would not work well. You would then have
poor braking or even none going down a
hill. You could crash. Always have the
engine running and your vehicle in gear
when you go downhill.
Know how to go down hills. The most important
thing to know is this: let the engine do some of
the slowing down. Shift to a lower gear when
you go down a steep or long hill.
Know how to go uphill. You may want to shift
down to a lower gear. The lower gears help
cool the engine and transmission, and you can
climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Do not swing wide
or cut across the center of the road. Drive at
speeds that let you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled
car or an accident.
You may see highway signs on mountains that
warn of special problems. Examples are long
grades, passing or no-passing zones, a falling
rocks area, or winding roads. Be alert to these
and take appropriate action.

How to Check Power Steering Fluid
To check the power steering uid, do the following:
1. Turn the ignition off and let the engine
compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with
a clean rag.
4. Replace the cap and completely tighten it.
5. Remove the cap again and look at the
uid level on the dipstick. There are markings
on both sides of the dipstick.
The level should be at the FULL COLD mark.
If necessary, add only enough uid to bring
the level up to the mark.When the engine
compartment is hot,
the level should
be at the HOT mark.
When the engine
compartment is
cool, the level
should be at the
FULL COLD mark.
What to Use
To determine what kind of uid to use, see
Recommended Fluids and Lubricants on page 443.
Always use the proper uid. Failure to use the
proper uid can cause leaks and damage
hoses and seals.

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The
repairs would not be covered by your
warranty. Always turn off your radio and
other accessories when jump starting
your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the
cigarette lighter or the accessory power outlet.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save
both batteries. And it could save the radio!
4. Open the hoods and locate the positive (+) and
negative (−) terminal locations on each vehicle.Your vehicle has a remote positive (+)
terminal (A) and a remote negative (−)
terminal (B), as shown in the illustration, which
should be used to jump start your vehicle.
The remote positive (+) terminal (A) can
be accessed by opening the cover of the
engine compartment fuse block.
The remote negative (−) terminal (B) is
located underneath the engine cover,
below the engine oil ll cap.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. TPMS sensors are mounted onto each
tire and wheel assembly. The TPMS sensors
monitor the air pressure in your vehicle’s tires
and transmit tire pressure readings to a receiver
located in the vehicle.
The TPMS is designed to alert the driver if a
low pressure condition exists. Using the Driver
Information Center (DIC), tire pressure levels can
be viewed by the driver. For additional information
and details about the DIC operation and displays
seeDIC Controls and Displays on page 208
andDIC Warnings and Messages on page 214.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located in the instrument panel
cluster. A DIC message to check the pressure in a
specic tire will also appear on the DIC display.The low tire pressure warning symbol on the
instrument panel cluster and the LOW TIRE
PRESSURE message on the DIC display will
appear at each ignition cycle until the tires
are inated to the correct ination pressure.
You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
DIC warning message will appear when the vehicle
is rst started and then turn off as you start to
drive the vehicle. This could be an early indicator
that the tire pressures are getting low and
need to be inated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire ination pressure label. (If your vehicle
has tires of a different size than the size indicated
on the vehicle placard or tire ination pressure
label, you should determine the proper tire
ination pressure for those tires.)
