protection needed in a crash. The
person wearing the belt could be (Continued)

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
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 safety
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 safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child restraints.
To wear it, attach it to the regular
safety belt. For more information,
see the instruction sheet that comes
with the extender.
Safety System Check
Check that the safety belt reminder,
safety belts, buckles, latch plates,
and retractors, are all working
properly. Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from performing properly. See your
dealer to have it repaired. Torn or
frayed safety belts may not protect
you in a crash. They can rip apart
under impact forces. If a belt is torn
or frayed, have it replaced
immediately.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders 0112.
Keep safety belts clean and dry.
See Safety Belt Care 064.
Safety Belt Care
Keep belts clean and dry.

Wireless Charging
The vehicle may have a wireless
charging pocket outside the armrest
of the center console. The system
wirelessly charges one PMA or Qi
compatible mobile device.
To check for phone or other device
compatibility:
.In the U.S., see my.buick.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 in ON/RUN,
ACC/ACCESSORY, or Retained
Accessory Power (RAP). The
wireless charging feature may not
correctly indicate charging when the
vehicle is in RAP. See
Retained
Accessory Power (RAP) 0178.
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 mobile device.
{Warning
Remove all metal objects from the
charging pocket before charging
your mobile phone. Metal objects,
such as coins, keys, rings,
or paper clips, between the
mobile phone and the charger will
become very hot. On the rare
occasion that the charging system
does not detect a metal object,
and the object gets wedged
between the mobile phone and
the charger, remove the mobile
phone and allow the metallic

problem with the lights or the
passenger sensing system. See
your dealer for service.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0113 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. The light turns off when the engine
is started. If it does not, have the
vehicle serviced by your dealer.
If the light stays on, or comes on
while driving, there could be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
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 (Check Engine
Light)
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 in
ON/RUN with the engine not
running for Key Access or in Service
Only Mode for Keyless Access. See
Ignition Positions
0173.
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.
