90 Seats and Restraints
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.
The best way to protect the fetus is
to protect the mother. When a seat
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Lap Belt
This section is only for the lap belt.
To learn how to wear a lap-shoulder
belt, seeLap-Shoulder Belt 085.
The vehicle may have a center
seating position with a lap seat belt.
The lap seat belt does not have a
retractor.
To make the belt longer, tilt the latch
plate and pull it along the belt.
Buckle, position, and release it the
same way as the lap part of a
lap-shoulder belt.
To make the belt shorter, pull its free
end as shown until the belt is snug.
If the belt is not long enough, see
Seat Belt Extender 091.
Make sure the release button on the
buckle is positioned so you would
be able to unbuckle the seat belt
quickly if necessary.
If you find that the latch plate will
not go fully into the buckle, see if
you are using the correct buckle. Be
sure that the latch plate clicks when
inserted into the buckle.

center console or on the center
stack for vehicles with bench seats, can be configured to
operate using Retained
Accessory Power (RAP) or
battery power modes. If these
power outlets are used while in
the battery power mode, this
could cause interference
between the Remote Keyless

140 Instruments and Controls
The power outlet is not designed for
the following, and may not work
properly if they are plugged in:
.Equipment with high initial peak
wattage, such as
compressor-driven refrigerators
and electric power tools
. Other equipment requiring
an extremely stable power
supply, such as
microcomputer-controlled
electric blankets and touch
sensor lamps
. Medical equipment
Wireless Charging
The vehicle may have wireless
charging on top of the center
console. See Center Console
Storage 0128. The system
operates at 145 kHz and wirelessly
charges one Qi compatible mobile
device. The power output of the
system is capable of charging at a
rate up to 1 amp (5W), as requested
by the compatible mobile device.
See Radio Frequency Statement
0 414. To check for phone or other device
compatibility:
.
In the U.S., see
my.chevrolet.com/learn.
. In Canada, see
gmtotalconnect.ca.
. Or, see your dealer for details.
{Warning
Wireless charging can affect the
operation of an implanted
pacemaker or other medical
devices. If you have one, it is
recommended to consult with
your doctor before using the
wireless charging system.
The vehicle must be on, in ACC/
ACCESSORY, or Retained
Accessory Power (RAP) must be
active. The wireless charging
feature may not correctly indicate
charging when the vehicle is in RAP.
See Retained Accessory Power
(RAP) 0224. The operating temperature is
−20 °C
(−4 °F) to 60 °C (140 °F) for the
charging system and 0 °C (32 °F) to
35 °C (95 °F) for the phone.
{Warning
Remove all objects from the
charging pad before charging
your mobile device. Objects, such
as coins, keys, rings, paper clips,
or cards, between the phone and
charging pad will become very
hot. On the rare occasion that the
charging system does not detect
an object, and the object gets
wedged between the phone and
charger, remove the phone and
allow the object to cool before
removing it from the charging
pad, to prevent burns.

Warning (Continued)
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0151 for more information,
including important safety
information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
It should go out when the engine is
started.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is on
with the engine not running for Key
Access or in Service Mode for
Keyless Access.
See
Ignition Positions (Key Access)
0 219 orIgnition Positions (Keyless
Access) 0217.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.

The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0288. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running.
. The light does not come on
when the ignition is on with the
engine not running for Key
Access or in Service Mode for
Keyless Access.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
When the ignition is on, the brake
system warning light also comes on
when the parking brake is set. The
light stays on if the parking brake
does not fully release. If it stays on
after the parking brake is fully
released, it means the vehicle has a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal can go closer to the
floor. It may take longer to stop.
If the light is still on, have the
vehicle towed for service. See
Towing the Vehicle 0372.
