{WARNING:
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 the 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 overfill the
tank and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. See Washing
Your Vehicle on page 6‑94.
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.
See Malfunction Indicator Lamp on page 4‑41. The CHECK GAS CAP message displays on the Driver
Information Center (DIC) if the fuel cap is not properly
installed. See
DIC Warnings and Messages
on
page 4‑52for more information.
{WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow 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 fit
properly. This may cause the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. See Malfunction Indicator Lamp
on page 4‑41.

Checking Engine Oil
(Except ZO6, ZR1, and Grand Sport)
If the CHECK OIL LEVEL message displays on the
Driver Information Center (DIC), check the engine oil
level right away. For more information, see Driver
Information Center (DIC)
on page 4‑47. Check the
engine oil level regularly; this is an added reminder.
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
See Engine Compartment Overview
on page 6‑14for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If this is not done,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a lint‐free paper towel or a cloth, then push it back in all
the way.
3. Remove the dipstick again, keeping the tip down and read the level on the cross‐hatched area.
Oil levels that fall in the cross‐hatched area are
normal.
4. Push the dipstick back in all the way.

If coolant is needed, add the proper DEX-COOL®
coolant mixture directly to the surge tank, but be sure
the cooling system is cool before this is done.
1. When the cooling system, including the coolant surge tank pressure cap and upper radiator hose,
is no longer hot, remove the pressure cap.
Turn the pressure cap slowly counterclockwise
about one-quarter turn and then stop.
If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.
2. Keep turning the pressure cap slowly, and remove it.
3. Fill the coolant surge tank with the proper DEX-COOL coolant mixture until the level inside
stabilizes at the FULL COLD mark on the front of
the surge tank.

4. Open the hoods and locate the positive (+) and negative (−) terminal locations on each vehicle.
6.2 L LS3 shown, 7.0 L LS7 and 6.2 L LS9 similar
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
fill cap.
See
Engine Compartment Overview
on page 6‑14for the location of the engine compartment fuse
block and engine oil fill cap.
You will not need to access the battery for jump
starting. The remote terminals are for that purpose.
{WARNING:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools away from any underhood
electric fan.

Notice:If the jumper cables are connected or
removed in the wrong order, electrical shorting
may occur and damage the vehicle. The repairs
would not be covered by the vehicle warranty.
Always connect and remove the jumper cables in
the correct order, making sure that the cables do
not touch each other or other metal.
Jumper Cable Removal
A. Heavy, Unpainted Metal Engine Part or Remote Negative (−) Terminal
B. Good Battery or Remote Positive (+) and Negative (−) Terminals
C. Dead Battery or Remote Positive (+) Terminal To disconnect the jumper cables from both vehicles, do
the following:
1. Disconnect the black negative (−) cable from the vehicle that had the dead battery.
2. Disconnect the black negative (−) cable from the vehicle with the good battery.
3. Disconnect the red positive (+) cable from the vehicle with the good battery.
4. Disconnect the red positive (+) cable from the other vehicle.
5. Return the engine fuse block cover to its original position.
6. You may also need to initialize the power windows. See “Power Window Initialize” underPower
Windows
on page 3‑17for more information.
