Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light 0114.
Child Restraints
Older Children
Older children who have outgrown
booster seats should wear the vehicle’s
seat belts.
The manufacturer instructions that
come with the booster seat state the
weight and height limitations for that
booster. Use a booster seat with a
lap-shoulder belt until the child
passes the fit test below:
.Sit all the way back on the seat. Do
the knees bend at the seat edge? If
yes, continue. If no, return to the
booster seat.
.Buckle the lap-shoulder belt. Does
the shoulder belt rest on the
shoulder? If yes, continue. If no, try
using the rear seat belt comfort
guide, if available. See “Rear Seat
Belt Comfort Guides” under
Lap-Shoulder Belt 056. If a comfort
guide is not available, or if the
shoulder belt still does not rest on
the shoulder, then return to the
booster seat.
.Does the lap belt fit low and snug
on the hips, touching the thighs? If
yes, continue. If no, return to the
booster seat.
.Can proper seat belt fit be
maintained for the length of the
trip? If yes, continue. If no, return
to the booster seat.
Q: What is the proper way to wear seat belts?
A: An older child should wear a
lap-shoulder belt and get the
additional restraint a shoulder belt
can provide. The shoulder belt
should not cross the face or neck.
The lap belt should fit snugly
below the hips, just touching the
top of the thighs. This applies belt

SEATS AND RESTRAINTS 75
Child restraints are devices used to
restrain, seat, or position children in
the vehicle and are sometimes called
child seats or car seats.
There are three basic types of child
restraints:
.Forward-facing child restraints
.Rear-facing child restraints
.Belt-positioning booster seats
The proper child restraint for your
child depends on their size, weight,
and age, and also on whether the
child restraint is compatible with the
vehicle in which it will be used. For each type of child restraint, there
are many different models available.
When purchasing a child restraint, be
sure it is designed to be used in a
motor vehicle. If it is, the child
restraint will have a label saying that
it meets federal motor vehicle safety
standards.
The instruction manual that is
provided with the child restraint
states the weight and height
limitations for that particular child
restraint. In addition, there are many
kinds of child restraints available for
children with special needs.
{Warning
To reduce the risk of neck and head
injury in a crash, infants and
toddlers should be secured in a
rear-facing child restraint until age
two, or until they reach the
maximum height and weight limits
of their child restraint.
{Warning
A young child's hip bones are still
so small that the vehicle seat belt
may not remain low on the hip
bones, as it should. Instead, it may
settle up around the child's
abdomen. In a crash, the belt would
apply force on a body area that is
unprotected by any bony structure.
This alone could cause serious or
fatal injuries. To reduce the risk of
serious or fatal injuries during a
crash, young children should always
be secured in an appropriate child
restraint.

DRIVING AND OPERATING 281
Lane Change Alert (LCA)
If equipped, the LCA system is a
lane-changing aid that assists drivers
with avoiding lane change crashes
that occur with moving vehicles in the
side blind zone (or spot) areas or with
vehicles rapidly approaching these
areas from behind. The LCA warning
display will light up in the
corresponding outside side mirror and
will flash if the turn signal is on.
{Warning
LCA does not alert the driver to
vehicles outside of the system
detection zones, pedestrians,
bicyclists, or animals. It may not
provide alerts when changing lanes
under all driving conditions. Failure
to use proper care when changing
lanes may result in injury, death,
or vehicle damage. Before making a
lane change, always check mirrors,
glance over your shoulder, and use
the turn signals.LCA Detection Zones
1. SBZA Detection Zone
2. LCA Detection Zone
The LCA sensor covers a zone of
approximately one lane over from
both sides of the vehicle, or 3.5 m
(11 ft). The height of the zone is
approximately between 0.5 m (1.5 ft)
and 2 m (6 ft) off the ground. The Side
Blind Zone Alert (SBZA) warning area
starts at approximately the middle of
the vehicle and goes back 5 m (16 ft).
Drivers are also warned of vehicles
rapidly approaching from up to 70 m
(230 ft) behind the vehicle.
How the System Works
The LCA symbol lights up in the side
mirrors when the system detects a
moving vehicle in the next lane over
that is in the side blind zone or
rapidly approaching that zone from
behind. A lit LCA symbol indicates it
may be unsafe to change lanes. Before
making a lane change, check the LCA
display, check mirrors, glance over
your shoulder, and use the turn
signals.
Left Side Mirror
DisplayRight Side Mirror Display
When the vehicle is started, both
outside mirror LCA displays will
briefly come on to indicate the system
is operating. When the vehicle is in a
forward gear, the left or right side
mirror display will light up if a moving
vehicle is detected in the next lane
over in that blind zone or rapidly
approaching that zone. If the turn

2. Push the bottom of the cover forward until the holes on the
cover line up with the holes on the
bumper.
3. Snap the hitch cover into place by pushing the upper corners forward.
4. Reinstall the two fasteners on the lower surface by turning clockwise.
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.Weight-Distributing Hitch
Adjustment
A weight-distributing hitch may be
useful with some trailers.
1. Front of Vehicle
2. Body to Ground Distance
When using a weight-distributing
hitch, measure the front fender height
above the front axle distance (2)
before and after connecting the trailer.
Adjust the spring bars until the front
fender height distance (2) is
approximately halfway between the
first and second measurements.
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 0337 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

322 VEHICLE CARE
Brakes
Disc brake linings have built-in wear
indicators that make a high-pitched
warning sound when the brake linings
are worn and new linings are needed.
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.
{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.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied, clearing up following several applications. This
does not mean something is wrong
with the brakes.
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 0394.
Brake pads should be replaced as
complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does
not return to normal height, or if
there is a rapid increase in pedal
travel. This could be a sign that brake
service may be required.
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement parts.
If this is not done, the brakes may not
work properly. The braking
performance can change in many ways if the wrong brake parts are
installed or if parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir is
filled with GM approved DOT 3 brake
fluid as indicated on the reservoir cap.
See
Engine Compartment Overview
0 308 for the location of the reservoir.
Checking Brake Fluid
With the vehicle in P (Park) on a level
surface, the brake fluid level should be
between the minimum and maximum
marks on the brake fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.Normal brake lining wear. When
new linings are installed, the fluid
level goes back up.

Tire Sidewall Labeling
Useful information about a tire is
molded into its sidewall. The
examples show a typical passenger
vehicle tire and a compact spare
tire sidewall.
Passenger (P-Metric) Tire Example
(1) Tire Size:The tire size is a
combination of letters and
numbers used to define a
particular tire's width, height,
aspect ratio, construction type,
and service description. See the
“Tire Size ”illustration in this
section. (2) TPC Spec (Tire Performance
Criteria Specification)
:Original
equipment tires designed to GM's
specific tire performance criteria
have a TPC specification code
molded onto the sidewall. GM's
TPC specifications meet or exceed
all federal safety guidelines.
(3) DOT (Department of
Transportation)
:The
Department of Transportation
(DOT) code indicates that the tire
is in compliance with the U.S.
Department of Transportation
Motor Vehicle Safety Standards.
DOT Tire Date of Manufacture
:
The last four digits of the TIN
indicate the tire manufactured
date. The first two digits represent
the week and the last two digits,
the year. For example, the third
week of the year 2020 would have
a 4-digit DOT date of 0320. Week
01 is the first full week (Sunday
through Saturday) of each year. (4) Tire Identification Number
(TIN)
:The letters and numbers
following the DOT (Department of
Transportation) code are the Tire
Identification Number (TIN). The
TIN shows the manufacturer and
plant code, tire size, and date the
tire was manufactured. The TIN is
molded onto both sides of the tire,
although only one side may have
the date of manufacture.
(5) Tire Ply Material
:The type
of cord and number of plies in the
sidewall and under the tread.
(6) Uniform Tire Quality
Grading (UTQG)
:Tire
manufacturers are required to
grade tires based on three
performance factors: tread wear,
traction, and temperature
resistance. For more information
see Uniform Tire Quality Grading
0 354.
