Brake Rotor Wear
ZR1 models have ceramic brake rotors. Rotors should
be visually inspected whenever the brake pads are
replaced. Rotors also need to be weighed before brake
pads are replaced to confirm that the rotor mass is
greater than the wear‐out mass printed on the rotor.
The rotor can be reused if the weight of the rotor is
above the mass limit. Rotor inspection and weighing
methods can be found in the service manual. See
Service Publications Ordering Information
on
page 8‑16.
Brake Rotor Protector
{WARNING:
Ceramic rotors will be very hot after operation and
touching them may cause burns. Be sure brake
system is completely cool prior to installation of
protector, or coming in contact with them. Notice:
Rotors may be chipped if hard contact is
made with the wheel during wheel installation or
removal. Always use the rotor protectors. Be sure
to carefully follow wheel removal and installation
instructions.

{DANGER:
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Vehicle Storage
{WARNING:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
are not careful. See Jump Starting
on page 6‑50
for tips on working around a battery without
getting hurt.
Infrequent Usage: Remove the black, negative (−) cable
from the battery to keep the battery from running down.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it
safely.
{WARNING:
Batteries can hurt you. They can be dangerous
because:
.They contain acid that can burn you.
.They contain gas that can explode or ignite.
.They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice: If you try to start your vehicle by pushing or
pulling it, you could damage your vehicle. Do not
push or pull your vehicle to start it; instead, use the
jump starting procedure in this manual to start your
vehicle when the battery has run down.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice:
If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would
not be able to start your vehicle, and the bad
grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in Neutral before setting the parking brakes.
Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the 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.
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.
6-51

{WARNING:
Using an open flame near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been blinded.
Use a flashlight if you need more light.
Be sure the battery has enough water. You do not
need to add water to the battery installed in your
new vehicle. But if a battery has filler caps, be
sure the right amount of fluid is there. If it is low,
add water to take care of that first. If you do not,
explosive gas could be present.
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
5. Check that the jumper cables do not have loose or missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will
go to positive (+) or to a remote positive (+)
terminal if the vehicle has one. Negative (−) will
go to a heavy, unpainted metal engine part or to a
remote negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−) or you
will get a short that would damage the battery and
maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.

Bulb Replacement
For the proper type of replacement bulbs, see
Replacement Bulbs on page 6‑58.
For any bulb changing procedure not listed in this
section, contact your dealer/retailer.
High Intensity Discharge (HID)
Lighting
{WARNING:
The low beam high intensity discharge lighting
system operates at a very high voltage. If you try
to service any of the system components, you
could be seriously injured. Have your dealer/
retailer or a qualified technician service them.
The vehicle may have HID headlamps. After an HID
headlamp bulb has been replaced, you may notice
that the beam is a slightly different shade than it was
originally. This is normal.
Halogen Bulbs
{WARNING:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.

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 vehicle
Warranty booklet for details. For additional
information refer to the tire manufacturer.
{WARNING:
.Poorly maintained and improperly used
tires are dangerous.
.Overloading your tires can cause
overheating as a result of too much
flexing. You could have an air-out and
a serious accident. SeeLoading the
Vehicle
on page 5‑28.
(Continued)
WARNING: (Continued)
.Underinflated 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. See Inflation - Tire Pressure
on
page 6‑70
.
.Overinflated 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.
See High-Speed Operation
on page 6‑72for
inflation pressure adjustment for high speed
driving.

Run-Flat Tires
This vehicle, when new, had run-flat tires. There is no
spare tire, no tire changing equipment, and no place to
store a tire in the vehicle. Run-flat tires perform so well
without any air that a Tire Pressure Monitor System
(TPMS) is used to alert you if a tire has lost pressure.
{WARNING:
When the low tire warning light is displayed on
the instrument panel cluster, 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. Do not drive over 55 mph (90 km/h)
when the low tire warning light is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If a tire goes flat, you will not need to stop on the side
of the road to change the tire. You can just keep on
driving. The shorter the distance you drive and the
slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated
run-flat tire for 25 miles (40 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that
the tire can be repaired. The tires on coupe, convertible
and Z06 models can operate effectively with no air
pressure for up to 100 miles (160 km) at speeds up
to 55 mph (90 km/h), but the tire would then have to
be replaced. The tires on ZR1 models can operate
effectively with no air pressure for up to 50 miles
(80 km) at speeds up to 55 mph (90 km/h), but the tire
would then have to be replaced. When a tire is filled
with air, it provides a cushion between the road and the
wheel. Because you will not have this cushion when
driving on a deflated tire, try to avoid potholes that could
damage your wheel and require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you have driven
on the tire in a deflated condition. When a tire has
been damaged, or if you have driven any distance on
a run-flat tire, check with an authorized run-flat tire
service center to determine whether the tire can be
repaired or should be replaced. To maintain your
vehicle's run-flat feature, all replacement tires must
be self-supporting tires. As soon as possible,
contact the nearest authorized GM or run-flat servicing
facility for inspection and repair or replacement.
