A vehicle-specific Certification label is
attached to the rear edge of the driver
door. It may show the gross weight
capacity of the vehicle, called the Gross
Vehicle Weight Rating (GVWR). The
GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.Caution
Overloading the vehicle may cause
damage. Repairs would not be covered by
the vehicle warranty. Do not overload the
vehicle.
{Warning
Things you put inside your vehicle
can strike and injure people in a
sudden stop or turn, or in a crash.
.Put things in the rear area of your
vehicle. Try to spread the weight
evenly.
.Never stack heavier things, like
suitcases, inside the vehicle so
that some of them are above the
tops of the seats.
.Do not leave an unsecured child
restraint in your vehicle.
.When you carry something inside
the vehicle, secure it whenever
you can.
Starting and Operating
New Vehicle Break-In
Follow these recommended guidelines
during the first 2 414 km (1,500 mi) of driving
this vehicle. Parts have a break-in period and
performance will be better in the long run. During the first 800 km (500 mi), engine
torque will be limited in low gears.
For the first 322 km (200 mi):
.To break in new tires, drive at moderate
speeds and avoid hard cornering.
.New brake linings also need a break-in
period. Avoid making hard stops. This is
recommended every time brake linings
are replaced.
For the first 800 km (500 mi):
.Avoid full throttle starts and abrupt stops.
.Do not exceed 4000 rpm.
.Avoid driving at any one constant speed,
fast or slow, including the use of cruise
control.
.Avoid downshifting to brake or slow the
vehicle when the engine speed will
exceed 4000 rpm.
.Do not let the engine labor. Never lug the
engine. This rule applies at all times, not
just during the break-in period.
For the first 2 414 km (1,500 mi):
.Do not participate in track events, sport
driving schools, or similar activities.
.Check engine oil with every refueling and
add if necessary. Oil and fuel
consumption may be higher than normal.

engine will not start in Service Mode. Press
ENGINE START/STOP again to turn the
vehicle off.
Starting the Engine
Caution
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
SeeAdd-On Electrical Equipment 0227.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Place the transmission in P (Park) or
N (Neutral). To restart the vehicle when it is
already moving, use N (Neutral) only.
Starting the Vehicle
The remote key must be inside the vehicle
for the ignition to work. Cell phone chargers can interfere with the
operation of the Keyless Access system.
Battery chargers should not be plugged in
when starting or turning off the engine.
1. Press the brake pedal, then press ENGINE START/STOP on the instrument panel.
If there is no remote key in the vehicle
or if there is something causing
interference with it, the Driver
Information Center (DIC) will display a
message.
2. When the engine begins cranking, let go of the button and the engine cranks
automatically until it starts.
If the battery in the remote key is weak,
the DIC will display a message. The
vehicle can still be driven.
See “Starting the Vehicle with a
Low Remote Key Battery” under
Remote Keyless Entry (RKE) System
Operation 07. If the remote key battery
is dead, insert it into the cupholder
remote key pocket to enable engine
starting.
3. Do not race the engine immediately after starting it. Operate the engine and
transmission gently until the oil warms
up and lubricates all moving parts. 4. If the engine does not start and no DIC
message is displayed, wait 15 seconds
before trying again to let the cranking
motor cool down.
If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the
accelerator. If the vehicle starts briefly
but then stops again, repeat these steps.
This clears the extra gasoline from the
engine.
Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.

Engine Oil
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 0238.
.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 0232 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.

236 Vehicle Care
{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.
4. Remove the dipstick again and read the level 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
0 304.
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 0232 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. O-ring Seal
3. Engine Oil Filter
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.
3. Remove the engine oil drain plug from the bottom of the engine oil pan. Drain
plug removal will let the oil drain from
the external oil tank and residual oil
from the crankcase sump. Allow the oil
to drain.

15342622) - 2022 - CRC - 5/4/21
Vehicle Care 237
4. Remove the engine oil filter and allowthe oil to drain.
5. Inspect the drain plug O-ring seal and replace if it is damaged. Reinstall the
drain plug into the oil pan and tighten it
to 25 N.m (18 lb ft).
6. Replace the oil filter and tighten it three-quarters to one turn after the
gasket makes contact. See Maintenance
Replacement Parts 0300 for the correct
filter.
7. Remove the oil fill cap from the external engine oil tank.
Add oil to the oil tank through the
opening in the fill tube. See Capacities
and Specifications 0304.
8. Install the oil fill cap and insert the dipstick, 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. 9. 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 0300.
Specification
Use engine oils that meet the dexos2
specification.
Engine oils that have been approved by GM
as meeting the dexos2 specification are
marked with the dexos2 approved logo. See
www.gmdexos.com.
GM recommends Mobil 1 engine oils that
show the dexos2 approved logo.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 0W-40 viscosity grade engine oil.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” previously in this section.
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos2
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
