266 Driving and Operating
Caution (Continued)
.Check engine oil with
every refueling and add if
necessary. Oil and fuel
consumption may be
higher than normal during
the first
2 414 km (1,500 mi).
.To break in new tires,
drive at moderate speeds
and avoid hard cornering
for the first
322 km (200 mi). New tires
do not have maximum
traction and may tend
to slip.
.New brake linings also
need a break-in period.
Avoid making hard stops
during the first
322 km (200 mi). This is
recommended every time
brake linings are replaced.
.Should the vehicle be used
for racing or competitive
driving (after break-in), the
rear axle lubricant must be
replaced beforehand.See Track Events and
Competitive Driving (V-Series
and V-Series Blackwing)
0246.
On new vehicles, the various
mechanical and electrical
systems experience a
“break-in” period during the
first 6,400 km (4,000 miles) of
routine driving. As the vehicle
is driven, the mechanical
systems adjust to provide
optimal fuel economy and
transmission shift
performance.
Electrical systems will adapt
and calibrate during the
break-in period. A one-time
occurrence of clicks and
similar vehicle noises is normal
during this process.
Normal driving charges the
vehicle’s battery to achieve
the best operation of the
vehicle, including fuel
economy.
Composite Materials
This vehicle may be equipped
with parts containing carbon
fiber, sheet-molding
compound, or other composite
materials. Dealer-installed
accessories may also contain
composite materials.
{Warning
Exposed edges of parts
containing carbon fiber and
other composite materials
can be sharp. Contact with
these parts could result in
injury. Use caution to avoid
contacting these parts,
including when washing the
vehicle. If the parts are
damaged, replace the parts
promptly with replacements
from your dealer.

If equipped, the following
driver assistance features
should be turned to alert or
off when towing a trailer:
.Automatic Emergency
Braking (AEB)
.Intelligent Brake Assist (IBA)
.Front Pedestrian
Braking (FPB)
If equipped with Lane Change
Alert (LCA), the LCA detection
zones that extend back from
the side of the vehicle do not
move further back when a
trailer is towed. Use caution
while changing lanes when
towing a trailer.
If equipped with Rear Cross
Traffic Alert (RCTA), use
caution while backing up when
towing a trailer, as the RCTA
detection zones that extend out from the back of the
vehicle do not move further
back when a trailer is towed.
{Warning
To prevent serious injury or
death from carbon monoxide
(CO), when towing a trailer:
.Do not drive with the
liftgate, trunk/hatch,
or rear-most
window open.
.Fully open the air outlets
on or under the
instrument panel.
.Adjust the climate control
system to a setting that
brings in only outside air.
See
“Climate Control
Systems” in the Index.
For more information about
carbon monoxide, see
Engine Exhaust 0276.
Towing a trailer requires
experience. The combination
of the vehicle and trailer is
longer and not as responsive as the vehicle itself. Become
familiar with handling and
braking by driving on a level
road surface before driving on
public roads.
The trailer structure, the tires,
and the brakes must be all be
rated to carry the intended
cargo. Inadequate trailer
equipment can cause the
combination to operate in an
unexpected or unsafe manner.
Before driving, inspect all
trailer hitch parts and
attachments, safety chains,
electrical connectors, lamps,
tires, and mirrors. See Towing
Equipment
0371. If the trailer
has electric brakes, start the
combination moving and then
manually apply the trailer
brake controller to check the
trailer brakes work. During the
trip, occasionally check that
the cargo and trailer are
secure and that the lamps and
any trailer brakes are working.

Trailer Towing (LSY
2.0L L4 and LGY 3.0L
V6 Engines Only)
Caution
Towing a trailer improperly
can damage the vehicle and
result in costly repairs not
covered by the vehicle
warranty. To tow a trailer
correctly, follow the
directions in this section and
see your dealer for
important information about
towing a trailer with the
vehicle.
Never tow a trailer with a
V-Series or V-Series
Blackwing. These models are
not designed or intended to
tow a trailer.
Trailer Weight
{Warning
Never exceed the towing
capacity for your vehicle.
Safe trailering requires
monitoring the weight, speed,
altitude, road grades, outside
temperature, dimensions of
the front of the trailer, and
how frequently the vehicle is
used to tow a trailer.
Before towing a trailer, always
separately weigh:
.the total weight on the
vehicle's tires.
.the trailer.
.the trailer tongue.
{Warning
You and others could be
seriously injured or killed if
the trailer is too heavy or
the trailer brakes are
inadequate for the load. The
vehicle may be damaged, (Continued)
Warning (Continued)
and the repairs would not be
covered by the vehicle
warranty.
Only tow a trailer if all the
steps in this section have
been followed. Ask your
dealer for advice and
information about towing a
trailer.
Gross Vehicle Weight
Rating (GVWR)
For information about the
vehicle's maximum load
capacity, see Vehicle Load
Limits0261. When calculating
the GVWR with a trailer
attached, the trailer tongue
weight must be included as
part of the weight the vehicle
is carrying.

2023 - CRC - 5/10/22
Driving and Operating 371
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going
by, and rough roads can affect
the trailer and the hitch.
Never attach rental hitches or
other bumper-type hitches.
Only use frame-mounted
hitches that do not attach to
the bumper.
Always seal any holes in your
vehicle if the trailer hitch
removed. If not sealed, dirt,
water, and carbon monoxide
(CO) from the exhaust may
enter your vehicle. See Engine
Exhaust0276.
Consider using mechanical
sway controls with any trailer.
Ask a trailering professional
about sway controls or refer to the trailer manufacturer's
recommendations and
instructions.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.
.Tires must be properly
inflated to support loads
while towing a trailer. See
Tires
0418 for instructions
on proper tire inflation.
Safety Chains
Always attach chains between
the vehicle and the trailer, and
attach the chains to the holes
on the trailer hitch platform.
Instructions about safety
chains may be provided by the
hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under
the tongue of the trailer to
help prevent the tongue from
contacting the road if it
becomes separated from the
hitch. Always leave just
enough slack so the combination can turn. Never
allow safety chains to drag on
the ground.
Trailer Brakes
Loaded trailers over 450 kg
(1,000 lb) must be equipped
with brake systems and with
brakes for each axle. Trailer
braking equipment conforming
to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent,
is recommended.
State or local regulations may
require trailers to have their
own braking system if the
loaded weight of the trailer
exceeds certain minimums
that can vary from state to
state. Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly. Never attempt to tap
into your vehicle's hydraulic
brake system. If you do, both
the vehicle anti-lock brakes

General
Information
For service and parts needs,
visit your dealer. You will
receive genuine GM parts and
GM-trained and supported
service people.
Genuine GM parts have one of
these marks:
California Perchlorate
Materials
Requirements
Certain types of automotive
applications, such as airbag
initiators, seat belt
pretensioners, and lithium
batteries contained in
electronic keys, may contain
perchlorate materials.
Perchlorate Material –special
handling may apply. See
www.dtsc.ca.gov/
hazardouswaste/perchlorate.
Accessories and
Modifications
Adding non-dealer accessories
or making modifications to the

Caution (Continued)
.Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of
the washer system.
.When using concentrated
washer fluid, follow the
manufacturer instructions
for adding water.
.Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if it
is completely full.
Brakes
Disc brake linings, except J57
V-Series Blackwing with
carbon ceramic brakes, have
built-in wear indicators that
make a high-pitched warning
sound when the brake linings
are worn and new linings areneeded. The sound can come
and go or can be heard all the
time when the vehicle is
moving, except when applying
the brake pedal firmly. The
V-Series Blackwing has
electronic pad wear sensors.
See Brake Pad Life System (If
Equipped)
0403
{Warning
The brake wear warning
sound means that soon the
brakes will not work well.
That could lead to a crash.
When the brake wear
warning sound is heard,
have the vehicle serviced.
Caution
Continuing to drive with
worn-out brake linings could
result in costly brake repairs.
Properly torqued wheel nuts
are necessary to help prevent
brake pulsation. When tires
are rotated, inspect brake linings for wear and evenly
tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities
and Specifications
0482.
Brake linings should be
replaced as complete
axle sets.
Brake Squeal and
Brake Dust
Some driving conditions or
climates can cause a brake
squeal when the brakes are
first applied, clearing up
following several applies. This
does not mean something is
wrong with the brakes.
Vehicles equipped with high
performance brake systems
provide superior fade
resistance, but will produce
increased brake squeal and
brake dust on the wheels and
calipers as compared to
standard brake linings. This is
normal.
