86 SEATS AND RESTRAINTS
A thick layer of additional material,
such as a blanket or cushion,
or aftermarket equipment such as seat
covers, seat heaters, and seat
massagers can affect how well the
passenger sensing system operates.
We recommend that you not use seat
covers or other aftermarket equipment
except when approved by GM for your
specific vehicle. SeeAdding Equipment
to the Airbag-Equipped Vehicle 087 for
more information about modifications
that can affect how the system
operates.
A wet seat can affect the performance
of the passenger sensing system. Here
is how:
. The passenger sensing system may
turn off the passenger frontal
airbag and passenger knee airbag
when liquid is soaked into the
seat. If this happens, the off
indicator will be lit, and the airbag
readiness light on the instrument
panel will also be lit.
. Liquid pooled on the seat that has
not soaked in may make it more
likely that the passenger sensing
system will turn on the passenger frontal airbag and passenger knee
airbag while a child restraint or
child occupant is on the seat.
If the passenger frontal airbag and
passenger knee airbag are turned
on, the on indicator will be lit.
If the passenger seat gets wet, dry the
seat immediately. If the airbag
readiness light is lit, do not install a
child restraint or allow anyone to
occupy the seat. See Airbag Readiness
Light 0126 for important safety
information.
The on indicator may be lit if an
object, such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device, is put on an unoccupied seat.
If this is not desired, remove the
object from the seat.
{Warning
Stowing articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle should
be serviced. There are parts of the
airbag system in several places around
the vehicle. Your dealer and the
service manual have information
about servicing the vehicle and the
airbag system. To purchase a service
manual, see Service Publications
Ordering Information 0366.
{Warning
For up to 10 seconds after the
vehicle is turned off and the battery
is disconnected, an airbag can still
inflate during improper service. You
can be injured if you are close to an
airbag when it inflates. Avoid
yellow connectors. They are
probably part of the airbag system.
Be sure to follow proper service
procedures, and make sure the
person performing work for you is
qualified to do so.

11349156) - 2018 - CRC - 9/29/17
SEATS AND RESTRAINTS 87
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet metal
may keep the airbag system from
working properly. The operation of the
airbag system can also be affected by
changing any parts of the front seats,
seat belts, airbag sensing and
diagnostic module, steering wheel,
instrument panel, inner door seals
including the speakers, any of the
airbag modules, ceiling or pillar
garnish trim, overhead console, front
sensors, side impact sensors, or airbag
wiring.
Your dealer and the service manual
have information about the location of
the airbag sensors, sensing and
diagnostic module, and airbag wiring.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
passenger seat. The passenger sensing
system may not operate properly if
the original seat trim is replaced withnon-GM covers, upholstery, or trim; or
with GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad or
device, installed under or on top of
the seat fabric, could also interfere
with the operation of the passenger
sensing system. This could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). See
Passenger Sensing
System 082.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0311 for additional important
information.
If you have to modify your vehicle
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. See Customer
Assistance Offices 0359.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0126.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 078. See
your dealer for service.

114 INSTRUMENTS AND CONTROLS
Lift the cover to access the accessory
power outlet.
Certain electrical accessories may not
be compatible with the accessory
power outlet and could overload a
vehicle circuit breaker or adapter fuse.
If overloaded, the circuit breaker will
reset after all devices are disconnected
or if Retained Accessory Power (RAP)
is turned off and then back on. See
Retained Accessory Power (RAP)0197.
Wait one minute to allow the circuit
breaker to reset before reconnecting
devices or turning RAP back on. If the
problem continues, the issue could be
within your device. Try another
known good device to make sure the
circuit breaker is operating properly.
If this does not resolve your problem,
see your dealer.
It is possible to replace the factory
power outlet with a cigar lighter
receptacle, if desired. This requires the
factory installed circuit breaker to be
replaced with a standard minifuse by
the dealer. A minifuse will not reset
and will have to be replace if blown.Caution
Failure to replace the circuit
breaker with the minifuse could
overheat the cigar lighter and
damage the vehicle.
When adding electrical equipment, be
sure to follow the proper installation
instructions included with the
equipment. See Add-On Electrical
Equipment 0251.
Caution
Adding any electrical equipment to
the vehicle may damage it or keep
other components from working as
they should. The repairs would not
be covered by the vehicle warranty.
Do not use equipment exceeding
maximum amperage rating of
15 amperes. Check with your dealer
before adding electrical equipment.
Caution
Hanging heavy equipment from the
power outlet can cause damage not
covered by the vehicle warranty.
The power outlets are designed for
accessory power plugs only, such as
cell phone charge cords.

CLIMATE CONTROLS 175
Operation Tips
.Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into the
vehicle.
. Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
. Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.
. Do not attach any devices to the
air vent slats. This restricts airflow
and may cause damage to the air
vents.Maintenance
Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle. The
filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule 0339.
See your dealer regarding replacement
of the filter.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained and
certified technicians. The air
conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be
replaced by a new evaporator to
ensure proper and safe operation. During service, all refrigerants should
be reclaimed with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to the
environment and may also create
unsafe conditions based on inhalation,
combustion, frostbite, or other
health-based concerns.

front. If the warning does not come
back on, continue to drive normally
and have the cooling system checked
for proper fill and function.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while parked.
If the warning is still displayed, turn
off the engine until it cools down.
Washer Fluid
What to Use
When windshield washer fluid is
needed, be sure to read the
manufacturer's instructions before
use. If operating the vehicle in an area
where the temperature may fall below
freezing, use a fluid that has sufficient
protection against freezing.
Adding Washer Fluid
Open the cap with the washer symbol
on it. Add washer fluid until the tank
is full. SeeEngine Compartment
Overview 0256 for reservoir location.
Caution
.
Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint.
(Continued)
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 pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be

VEHICLE CARE 277
The brake master cylinder reservoir is
filled with GM approved DOT 3 brake
fluid as indicated on the reservoir cap.
SeeEngine Compartment Overview
0 256 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.
. A fluid leak in the brake hydraulic
system. Have the brake hydraulic
system fixed. With a leak, the
brakes will not work well.
Always clean the brake fluid reservoir
cap and the area around the cap
before removing it.
Do not top off the brake fluid. Adding
fluid does not correct a leak. If fluid is
added when the linings are worn,
there will be too much fluid when new brake linings are installed. Add or
remove fluid, as necessary, only when
work is done on the brake hydraulic
system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You or
others could be burned, and the
vehicle could be damaged. Add
brake fluid only when work is done
on the brake hydraulic system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning Light
0 129.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid at
the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0339. What to Add
Use only GM approved DOT 3 brake
fluid from a clean, sealed container.
See
Recommended Fluids and
Lubricants 0348.{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.
Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the paint
finish can be damaged. Immediately
wash off any painted surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove the
cap and do not add fluid.
