warning CHEVROLET CORVETTE 2007 6.G Service Manual

The SERVICE
TRACTION SYSTEM
message and the
TCS warning light will
come on to let you know
if there is a problem
with your TCS system.
SeeDIC Warnings
and Messages
on page 214.
When this light and the SERVICE TRACTION
SYSTEM message are on, the system will not
limit wheel spin. Adjust your driving accordingly.
The TCS system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions,
you should always leave the system on. But you
can turn the TCS system off if you ever need to.To turn the system off,
press the button located
on the console.
You can turn the system on or off at any time by
pressing the ACTIVE HANDLING button. The
DIC will display the appropriate message when
you push the button.
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.

Adding non-dealer accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 319for more information.
Active Handling System
The Active Handling System is a computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively
applying any one of the vehicle’s brakes.
When you rst start your vehicle during cold winter
weather and begin to drive away, the message
ACTIVE HANDLING WARMING UP may be
displayed in the DIC. This is normal. You can
acknowledge this message by pressing the RESET
button. The Active Handling System performance
is affected until the message, ACTIVE HANDLING
READY, is displayed in the DIC.
The ACTIVE HANDLING CALIBRATING message
may be displayed in the DIC and the instrument
panel cluster light will be on after exceeding
18 mph (30 km/h) for 10 seconds. The Active
Handling System is off until the ACTIVE
HANDLING READY message is displayed.
This could take up to 15 minutes.The ACTIVE HANDLING message will come on
when the system is operating. SeeDIC Warnings
and Messages on page 214for more information.
You may also feel or hear the system working.
This is normal.
The SERVICE ACTIVE
HANDLING message
will be displayed, the
instrument cluster light
will come on, and a
chime will sound to let
you know if there is a
problem with the system.
SeeDIC Warnings and Messages on page 214for
more information.
When this light and the SERVICE ACTIVE
HANDLING SYSTEM message are on, the system
is not operational. Adjust your driving accordingly.

Selective Ride Control
You may have a ride control system on your
vehicle called Magnetic Selective Ride Control.
The system provides the following performance
benets:
Reduced Impact Harshness
Improved Road Isolation
Improved High-Speed Stability
Improved Handling Response
Better Control of Body Ride Motions
This knob is located
on the center console.
Turn it to select the
suspension of your
choice.
TOUR:Use for normal city and highway driving.
This setting provides a smooth, soft ride.SPORT:Use where road conditions or personal
preference demand more control. This setting
provides more “feel”, or response to the road
conditions.
You can select a setting at any time. Based on road
conditions, steering wheel angle and your vehicle
speed, the system automatically adjusts to provide
the best ride and handling. Select a new setting
whenever driving conditions change.
There are three Driver Information Center (DIC)
messages that are displayed when a
malfunction occurs with the Selective Ride
Control system (SERVICE RIDE CONTROL,
SHOCKS INOPERATIVE, MAXIMUM SPEED
80 MPH (129 KM/H). Refer toDIC Warnings and
Messages on page 214for more information.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning,
you can steer but it will take much more effort.
286

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you
want the vehicle to go. If you start steering quickly
enough, your vehicle may straighten out. Always
be ready for a second skid if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle
control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road
to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal
use. Low oil levels can damage the engine.
For information on how to add oil, see
Engine Oil on page 333.
Z06 Only: Be sure to check the oil level often
during racing or other competitive driving
and keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.
Except Z06: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
After the competitive driving, remove excess
oil so that the level on the dipstick is not
above the upper mark that shows the proper
operating range.
292

Driving too fast through large water puddles or
even going through some car washes can cause
problems, too. The water may affect your
brakes. Try to avoid puddles. But if you cannot,
try to slow down before you hit them.
Hydroplaning
Hydroplaning is dangerous. So much water can
build up under your tires that they can actually ride
on the water. This can happen if the road is wet
enough and you are going fast enough. When your
vehicle is hydroplaning, it has little or no contact
with the road.
Hydroplaning does not happen often. But it can
if your tires do not have much tread or if the
pressure in one or more is low. It can happen if
a lot of water is standing on the road. If you
can see reections from trees, telephone poles,
or other vehicles, and raindrops dimple the
water’s surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds.
There just is not a hard and fast rule about
hydroplaning. The best advice is to slow down
when it is raining.
Driving Through Deep Standing Water
Notice:If you drive too quickly through deep
puddles or standing water, water can come
in through the engine’s air intake and badly
damage the engine. Never drive through water
that is slightly lower than the underbody of your
vehicle. If you cannot avoid deep puddles or
standing water, drive through them very slowly.
Driving Through Flowing Water
{CAUTION:
Flowing or rushing water creates strong
forces. If you try to drive through owing
water, as you might at a low water
crossing, your vehicle can be carried away.
As little as six inches of owing water
can carry away a smaller vehicle. If this
happens, you and other vehicle occupants
could drown. Do not ignore police warning
signs, and otherwise be very cautious
about trying to drive through owing water.
296

Here are ways to increase your safety in
city driving:
Know the best way to get to where you are
going. Get a city map and plan your trip
into an unknown part of the city just as you
would for a cross-country trip.
Try to use the freeways that rim and crisscross
most large cities. You will save time and
energy. SeeFreeway Driving on page 298.
Treat a green light as a warning signal.
A traffic light is there because the corner
is busy enough to need it. When a light turns
green, and just before you start to move,
check both ways for vehicles that have not
cleared the intersection or may be running
the red light.
Freeway Driving
Mile for mile, freeways — also called thruways,
parkways, expressways, turnpikes, or
superhighways — are the safest of all roads.
But they have their own special rules.
298

Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter.
You may want to put winter emergency
supplies in your vehicle.
Also seeTires on page 378.Include an ice scraper, a small brush or broom,
a supply of windshield washer uid, a rag,
some winter outer clothing, a small shovel, a
ashlight, a red cloth, and a couple of reective
warning triangles. And, if you will be driving under
severe conditions, include a small bag of sand,
a piece of old carpet, or a couple of burlap bags
to help provide traction. Be sure you properly
secure these items in your vehicle.

California Proposition 65 Warning
Most motor vehicles, including this one, contain
and/or emit chemicals known to the State of
California to cause cancer and birth defects
or other reproductive harm. Engine exhaust,
many parts and systems (including some
inside the vehicle), many uids, and some
component wear by-products contain and/or
emit these chemicals.
Doing Your Own Service Work
{CAUTION:
You can be injured and your vehicle
could be damaged if you try to do
service work on a vehicle without
knowing enough about it.
Be sure you have sufficient
knowledge, experience, the proper
replacement parts, and tools
before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts,
and other fasteners. English and
metric fasteners can be easily
confused. If you use the wrong
fasteners, parts can later break or
fall off. You could be hurt.

While refueling, let the cap hang by the tether
below the fuel ll opening.
{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 411.
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 caphas been left off or improperly installed. This would
allow fuel to evaporate into the atmosphere. See
Malfunction Indicator Lamp on page 200.
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 214for 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 200.
