Accessories and
Modifications
Adding non-dealer accessories or
making modifications to the vehicle
can affect vehicle performance and
safety, including such things as
airbags, braking, stability, ride and
handling, emissions systems,
aerodynamics, durability, and
electronic systems like antilock
brakes, traction control, and stability
control. These accessories or
modifications could even cause
malfunction or damage not covered
by the vehicle warranty.Damage to suspension components
caused by modifying vehicle height
outside of factory settings will not be
covered by the vehicle warranty.
Damage to vehicle components
resulting from modifications or the
installation or use of non-GM
certified parts, including control
module or software modifications, is
not covered under the terms of the
vehicle warranty and may affect
remaining warranty coverage for
affected parts.
GM Accessories are designed to
complement and function with other
systems on the vehicle. See your
dealer to accessorize the vehicle
using genuine GM Accessories
installed by a dealer technician.
Also, see
Adding Equipment to the
Airbag-Equipped Vehicle 079.
Lifting the Vehicle
{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatictransmission in P (Park) or a
manual transmission in

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0227.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Z06, Grand Sport, and Stingray
with Z51)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away.
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0217 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the
engine oil level on steep grades

Vehicle Care 235
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 a hiss is heard, 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 mixture until the
level inside stabilizes at the
cold fill line on the front of the
surge tank.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until the
upper radiator hose can be felt
getting hot. Any time during
this procedure, watch out for
the engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is lower, add more of the proper
mixture to the coolant surge
tank until the level stabilizes at
the cold fill line on the coolant
surge tank.
5. Replace the pressure cap tightly.
6. Verify coolant level after the engine is shut off and the
coolant is cold. If necessary,
repeat coolant fill procedure
Steps 1−6.
If the coolant still is not at the
proper level when the system
cools down again, see your
dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
Cooling System (Aero
Panel)
The aero panel enhances
aerodynamic efficiency and
improves fuel economy.
Remove the aero panel and bracket
to improve engine cooling and air
conditioning performance when
driving aggressively or in hot
weather.
