some new parts for the
airbag system. If you do not
get them, the airbag system
will not be there to help
protect you in another crash.
A new system will include
airbag modules and possibly
other parts. The service
manual for the vehicle
covers the need to replace
other parts.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy0448 and
Event Data Recorders 0449.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator 0125.
The passenger sensing
system turns off the front
outboard passenger frontal
airbag and knee airbag under certain conditions. No other
airbag is affected by the
passenger sensing system.
The passenger sensing
system works with sensors
that are part of the front
outboard passenger seat and
seat belt. The sensors are
designed to detect the
presence of a properly seated
occupant and determine if the
front outboard passenger
frontal airbag and knee airbag
should be allowed to inflate
or not.
According to accident
statistics, children are safer
when properly secured in a
rear seat in the correct child
restraint for their weight
and size.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.

16412876) - 2023 - CRC - 3/25/22
98 Seats and Restraints
If the head restraint was
removed, reinstall it before the
seating position is used. See
"Head Restraint Removal and
Reinstallation" under Lower
Anchors and Tethers for
Children (LATCH System)086
for additional information on
installing the head restraint
properly.
Securing Child
Restraints (With the
Seat Belt in the
Front Seat)
This vehicle has airbags.
A rear seat is a safer place to
secure a forward-facing child
restraint. See Where to Put
the Restraint 085.
In addition, the vehicle has a
passenger sensing system
which is designed to turn
off the front outboard
passenger frontal and
knee airbag under certain
conditions. See Passenger
Sensing System 072 and Passenger Airbag Status
Indicator
0125 for more
information, including
important safety information.
Never put a rear-facing child
seat in the front. This is
because the risk to the
rear-facing child is so great,
if the airbag deploys.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the front
outboard passenger frontal
airbag inflates. This is
because the back of the
rear-facing child restraint
would be very close to the
inflating airbag. A child in a
forward-facing child
restraint can be seriously
injured or killed if the front
outboard passenger frontal
airbag inflates and the
passenger seat is in a
forward position.
(Continued)
Warning (Continued)
Even if the passenger
sensing system has turned
off the front outboard
passenger airbag(s), no
system is fail-safe. No one
can guarantee that an
airbag will not deploy under
some unusual circumstance,
even though the airbag(s)
are off.
Secure rear-facing child
restraints in a rear seat,
even if the airbag(s) are off.
If you secure a
forward-facing child
restraint in the front
outboard passenger seat,
always move the seat as far
back as it will go. It is better
to secure the child restraint
in a rear seat.
See Passenger Sensing
System072 for additional
information.

enough to cause an expensive
repair or replacement. Paying
attention to the warning lights
and gauges could prevent
injury.

126 Instruments and Controls
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. Find a safe
place to stop the vehicle.
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 Service Mode. See Ignition
Positions
0247.
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.
Caution
Modifications to the engine,
transmission, exhaust,
intake, or fuel system, or the
use of replacement tires
that do not meet the original
tire specifications, can cause

Maps
The Navigation application
requires a map database to
run. It is stored on an SD card
that is connected to the
infotainment system. If the
map database is not available,
a missing SD card error
message will be displayed.
SD Card Error Messages
The SD card only works for
one unique vehicle. The SD
card must pass authentication
verification to be used for that
specific vehicle. If the SD card
has a switch that can be set to
read-only mode, ensure that it
is in the upward position and
not in read-only.
Potential error scenarios and
messages include:
.The SD card has initialized
for the first time:“Once
initialized, this SD card can
only be used for navigation
in this vehicle.”
.The SD card is not working
properly: “SD card is not
functioning properly.
(Error Code).”
See your dealer if this
message appears.
.The SD card is not paired
with the existing system:
“This SD card is not valid in
this vehicle for navigation.
See Owner’s Manual for
more detail or visit your
dealer. (Error Code).”
.The SD card has been
removed from the slot: “SD
card has been removed.
(Error Code).”
Make sure the SD card is in
the slot. If it was removed
and inserted and you still
receive an error code, see
your dealer. Touch Confirm to resume
after the initialization error
message. For the other
messages, touch OK to return
to the Home Page.
