2005 CHEVROLET CORVETTE tire pressure

TIRE FLAT:You will hear two chimes when this
message is displayed followed by the message
MAXIMUM SPEED 55 MPH (90 km/h). Also, the tire
pressure light on the instrument panel cluster will come
on. SeeTire Pressure Light on page 3-42. If this
message appears, do not drive your vehicle above this
limit. The next message to appear is REDUCED
HANDLING. The active handling system will intervene
more quickly when a at tire has been detected.
Adjust your driving accordingly. To acknowledge these
warnings, press the RESET button. After you press
the RESET button, a message will reappear every
10 minutes until this condition changes. This message
indicates that the pressure in one of your tires is
lower than 10 psi (68 kPa). Next to the TIRE FLAT
message, you can see either LEFT FRONT, RIGHT
FRONT, LEFT REAR or RIGHT REAR to indicate to you
which tire is at. You can receive more than one tire
pressure message at a time. To read other messages
that may have been sent at the same time, press
the RESET button. 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 your Tire
Loading Information Label. SeeExtended Mobility
Tires on page 5-56andInation - Tire Pressure on
page 5-58.
{CAUTION:
When the LOW TIRE PRESSURE or TIRE FLAT
message is displayed on the Driver Information
Center, your vehicle’s handling capabilities will
be reduced during severe maneuvers. If you
drive too fast, you could lose control of your
vehicle. You or others could be injured. Don’t
drive over 55 mph (90 km/h) when the LOW
TIRE PRESSURE or TIRE FLAT message is
displayed. Drive cautiously and check your tire
pressures as soon as you can.
TOO COLD TO MOVE TOP:This message displays
and a chime sounds when the power convertible
top button is pressed and the power convertible top
pump motor temperature is below -4°F (-20°C). Wait for
the power convertible top pump motor to warm up
before using the power convertible top.

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel.The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.

To turn the system off,
press the ACTIVE
HANDLING button on the
console for ve seconds.
You can turn the
system on and off at any
time by pressing the
button. The DIC will display
the appropriate message
when you push the button.
If the Tire Pressure Monitor (TPM) system detects a at
tire and the Driver Information Center (DIC) displays
TIRE FLAT, or if the TPM system is malfunctioning and
the DIC displays SERVICE TIRE MONITOR, the
Active Handling System will be affected as follows:
The Active Handling System cannot be turned off by
the driver.
If the Active Handling System is off, it will be turned
on automatically.
Competitive Driving Mode is unavailable.
The Active Handling System will feel different in
aiding and maintaining directional control.
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. A chime
will sound and 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 steer the
vehicle by selective brake application. 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.
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.
4-11

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 your engine’s air intake and badly damage
your 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.
Some Other Rainy Weather Tips
Besides slowing down, allow some extra following
distance. And be especially careful when you
pass another vehicle. Allow yourself more clear
room ahead, and be prepared to have your
view restricted by road spray.
Have good tires with proper tread depth. SeeTires
on page 5-51.

The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles that
rst part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course, you
will nd experienced and able service experts in GM
dealerships all across North America. They will be ready
and willing to help if you need it.Here are some things you can check before a trip:
Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
Lamps:Are they all working? Are the lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inated to the
recommended pressure?
Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps:Do you have up-to-date maps?

Tire and Loading Information Label
A vehicle specic Tire and Loading Information label is
attached to the center pillar (B-pillar) of your vehicle. With
the driver’s door open, you will nd the label attached
below the door latch. This label shows the number of
occupant seating positions (A), and the maximum vehicle
capacity weight (B) in kilograms and pounds.
The Tire and Loading Information label also shows the
size of the original equipment tires (C) and the
recommended cold tire ination pressures (D). For more
information on tires and ination seeTires on page 5-51
andInation - Tire Pressure on page 5-58.There is also important loading information on the
vehicle Certication label. It tells you the Gross Vehicle
Weight Rating (GVWR) and the Gross Axle Weight
Rating (GAWR) for the front and rear axle. See
“Certication Label” later in this section.
Steps for Determining Correct Load Limit
1. Locate the statement “The combined weight of
occupants and cargo should never exceed
XXX kg or XXX pounds” on your vehicle’s placard.
2. Determine the combined weight of the driver and
passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and
passengers from XXX kilograms or XXX pounds.
4. The resulting gure equals the available amount of
cargo and luggage load capacity. For example, if
the “XXX” amount equals 1400 lbs and there will be
ve 150 lb passengers in your vehicle, the amount
of available cargo and luggage load capacity is
650 lbs (1400−750 (5 x 150) = 650 lbs).
5. Determine the combined weight of luggage and
cargo being loaded on the vehicle. That weight
may not safely exceed the available cargo
and luggage load capacity calculated in Step 4. Label Example

Tires
Your new vehicle comes with high-quality tires made by
a leading tire manufacturer. If you ever have questions
about your tire warranty and where to obtain service,
see your GM Warranty booklet for details. For additional
information refer to the tire manufacturer’s booklet
included with your vehicle’s Owner’s Manual.{CAUTION:
Poorly maintained and improperly used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an air-out and a
serious accident. SeeLoading Your
Vehicle on page 4-31.
Underinated tires pose the same danger
as overloaded tires. The resulting accident
could cause serious injury. Check all tires
frequently to maintain the recommended
pressure. Tire pressure should be checked
when your tires are cold.
Overinated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a pothole.
Keep tires at the recommended pressure.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.
SeeInflation - Tire Pressure on page 5-58for
ination pressure adjustment for high speed
driving.
