Brakes
Battery Disconnect
Disconnect the battery before servicing the
hydraulic brake system. It is critical to
disconnect the battery before bleeding the
system, replacing the pads, or any other
work. The battery must be disconnected to
prevent the brake master cylinder from
pressurizing the hydraulic system during its
automated self diagnostic tests that can
occur when a door is opened or the remote
key is present.
{Warning
To avoid personal injury and/or vehicle
damage, always disconnect the battery
before performing service work on the
hydraulic brake system. Bleeding the
brake system with the battery connected
can lead to the system diagnosing a leak
or air in the braking system. A Diagnostic
Trouble Code (DTC) may set and vehicle
speed may be limited.Brake Fluid
Replace existing brake fluid with a qualified
high performance DOT 4 brake fluid from a
sealed container. Brake fluid with a dry
boiling point >310 °C (590 °F) is qualified.
If high performance brake fluid is used,
replace it with GM approved brake fluid
before driving on public roads. If high
performance brake fluid is in the vehicle and
the age of the brake fluid is over a month
old or unknown, replace the brake fluid
before track events and competitive driving.
Do not use silicone or DOT-5 brake fluids.
Check the fluid level before each competitive
driving event.
Brake System Flushing and Bleeding
The J55, J56, and J57 brake systems require
specific processes for bleeding and fluid
flushing. These can be found in the service
manual.
Properly bleeding the brake system is
required for proper operation of the
hydraulic brake system. Brake Leak Detection
The hydraulic braking system has advanced
diagnostic capability to help detect hydraulic
leaks, trapped air, and other performance
issues. These diagnostics are active when
the hydraulic system is powered. To avoid
inadvertently setting a leak DTC, disconnect
the battery before servicing the brake
system.
If the vehicle sets a DTC related to a brake
system leak, the Brake System Warning
Light will come on and vehicle speed may
be limited to 100 kph (62 mph). Any time a
leak DTC is set, the vehicle should be
inspected carefully for evidence of a leak
and should be repaired immediately. See
your dealer.
Brake Fade Warning Assist
The Brake Fade Warning Assist system
monitors brake system performance. If the
system detects brake fade, or if the brake
fluid is near the boiling point, the driver will
be alerted.
The Brake Fade Warning Assist system is
designed for use with the factory-installed
brake pads or GM approved replacement
pads. If the brake pads on the vehicle need

Engine Oil (5.5L LT6 Engine)
To ensure proper engine performance and
long life, pay careful attention to engine oil.
Follow these important steps:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See“Selecting the Right Engine
Oil” later 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” later in this section.
.Change the engine oil at the appropriate
time. SeeEngine Oil Life System 0252.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking the Engine Oil
1. Engine Oil Dipstick
2. Engine Oil Fill Cap
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. To get an accurate reading, the vehicle
must be parked on a level ground.
The engine oil dipstick handle is a loop. See
Engine Compartment Overview 0238 for the
location.
The vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differently
than a standard engine lubrication system
and requires a special procedure when
checking the engine oil level. Follow this
procedure closely.
The engine oil level must be checked when
the engine is warm. Cold oil level in the dry
sump tank may not indicate the actual
amount of oil in the system. Engine oil is
contained in an external tank, separate from
the engine. Under normal operating
conditions, the oil pan under the engine
does not store any oil. If the vehicle has
been parked for an extended period without
the engine being started, some oil will seep
back into the oil pan. This will reduce the
amount of oil held in the dry sump tank and there could be no engine oil on the
dipstick. This is normal since the dipstick is
designed to read the engine oil level only
after the engine has run long enough to
reach normal operating temperature. Do not
add engine oil based on cold engine dipstick
readings. The engine oil level on the dipstick
must be checked while the engine is running
at idle.
To check the engine oil:
1. Turn the engine on and let it warm up to at least 80 °C (175 °F).
2. Once the engine is warm, check the oil while the engine is running at idle.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
3. Remove the dipstick and wipe it with a clean lint-free paper towel or a cloth.
Re-insert the dipstick and push it all the
way in until it stops.

17272984) - 2024 - CRC - 2/20/23
Vehicle Care 247
4. Remove the dipstick again and read thelevel on the cross-hatched area. Re-insert
the dipstick and push it all the way in
until it stops.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick, add 1 L (1 qt) of the
recommended oil through the oil fill cap
opening in the oil tank fill tube and then
recheck the level. See “Selecting the Right
Engine Oil” later in this section for the type
of oil to use. For engine oil crankcase
capacity, see Capacities and Specifications
0 325.
Caution
Do not add too much oil. Oil levels above
or below the acceptable operating range
shown on the dipstick are harmful to the
engine. If the oil level is above the
operating range (i.e., the engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range), the engine could be
damaged. Drain the excess oil or limit
driving of the vehicle, and seek a service
professional to remove the excess oil.
See Engine Compartment Overview 0238 for
the location of the external engine oil tank
dipstick and fill cap.
Add enough oil to put the level somewhere
in the proper operating range. Push the
dipstick all the way back into the oil tank
tube when finished.
Changing the Engine Oil and Filter
The vehicle requires a special procedure
when changing the engine oil and filter.
Follow this procedure closely.
1. Engine Oil Drain Plug
2. Drain Plug O-ring Seal
3. Engine Oil Drain Plug
4. Drain Plug O-ring Seal
5. Engine Oil Filter Cap
6. Engine Oil Filter Cap O-ring Seal
7. Engine Oil Filter Element
To change the engine oil and filter:
1. Run the engine at idle for about 20 seconds to return all of the oil back
into the dry sump oil tank.
2. Turn the engine off prior to draining the oil and remove the oil fill cap so the oil
tank can breathe while it’s draining.

3. Remove the engine oil drain plug (1)from the bottom of the engine oil tank.
Drain plug removal will let the oil drain
from the external oil tank. Allow the oil
to drain.
4. Inspect the drain plug O-ring seal (2) and replace if it is damaged. Reinstall the
drain plug into the oil tank by rotating it
to a stop.
5. Remove the engine oil drain plug (3) from the bottom of the engine
crankcase. Drain plug removal will let the
residual oil drain from crankcase sump.
Allow the oil to drain.
6. Inspect the drain plug O-ring seal (4) and replace if it is damaged. Reinstall the
drain plug into the crankcase sump and
tighten them to 25 Y(18 lb ft).
7. Remove the engine oil filter cap (5) and filter (7) and allow the oil to drain.
8. Install the engine oil filter cap (5) with a new engine oil filter cap seal ring (6) and
the new oil filter element (7) and hand
tighten. See Maintenance Replacement
Parts 0321 for the correct filter.
Tighten the engine oil filter cap (5) to
25 Y (18 lb ft). 9. Add oil to the oil tank through the
opening in the oil tank. See Capacities
and Specifications 0325.
10. Install the oil fill cap and insert the dipstick until fully seated to a stop,
if removed.
{Warning
To help avoid personal injury and/or
engine damage, always install the engine
oil dipstick and oil fill cap until fully
seated to a stop. If not fully seated, oil
could escape on to hot exhaust parts and
cause a fire.
11. Start the engine and check the oil level as described under "Checking the Engine
Oil." previously in this section.
Selecting the Right Engine Oil
Selecting the right engine oil depends on
both the proper oil specification and the
viscosity grade. See Recommended Fluids
and Lubricants 0320.
Specification
Use engine oils that meet the dexosR
Performance Engine Oil specification.
Engine oils that have been approved by GM
as meeting the dexosR specification are
marked with the dexosR approved logo. See
www.gmdexos.com.
GM recommends Mobil 1 engine oils that
show the dexosR approved logo.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.

Vehicle Care 249
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos
specification are all that is needed for good
performance and engine protection.
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can be unhealthy for your skin and
could even cause cancer. Do not let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer's warnings
about the use and disposal of oil products.
Used oil can be a threat to the environment.
If you change your own oil, drain all the oil
from the filter before disposal. Never dispose
of oil by putting it in the trash or pouring it
on the ground, into sewers, or into streams
or bodies of water. Recycle it by taking it to
a place that collects used oil.
