68 Seats and Restraints
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 instrument panel
when the vehicle is started.
The words ON and OFF will be
visible during the system check.
When the system check is
complete, either the word ON or
OFF will be visible. SeePassenger
Airbag Status Indicator 0108.
The passenger sensing system
turns off the front outboard
passenger frontal 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.
The sensors are designed to detect
the presence of a properly-seated
occupant and determine if the front
outboard passenger frontal 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 age
12 and under should be secured in
a rear seating position.
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 inflates.
{Warning
A child in a rear-facing child
restraint can be seriously injured
or killed if the passenger frontal
airbag inflates. This is because
(Continued)
Warning (Continued)
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
passenger frontal airbag inflates
and the passenger seat is in a
forward position.
Even if the passenger sensing
system has turned off the
passenger frontal airbag, no
system is fail-safe. No one can
guarantee that an airbag will not
deploy under some unusual
circumstance, even though the
airbag is turned off.
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing 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 child restraints in the rear(Continued)

6. If the child restraint has a toptether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System) 080.
7. Before placing a child in the child restraint, make sure it is
securely held in place. To
check, grasp the child restraint
at the safety belt path and
attempt to move it side to side
and back and forth. When the
child restraint is properly
installed, there should be no
more than 2.5 cm (1 in) of
movement.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it.Securing Child Restraints
(With the Safety Belt in
the Front Seat)
The vehicle has airbags. A rear seat
is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 079.
In addition, the vehicle has a
passenger sensing system which is
designed to turn off the front
outboard passenger frontal airbag
under certain conditions. See
Passenger Sensing System 068
and Passenger Airbag Status
Indicator 0108 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

Voltmeter Gauge
When the engine is not running, but
the ignition is turned on, this gauge
shows the battery's state of charge
in DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
idling for an extended period.
If there is a problem with the battery
charging system, a SERVICE
BATTERY CHARGING SYSTEM
message will appear in the Driver
Information Center (DIC) and/or the
charging system light comes on.
See
Battery Voltage and Charging
Messages 0124 for more
information.
However, readings in either warning
zone may indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their safety belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver safety belt is buckled,
neither the light nor the chime
comes on.
Passenger Safety Belt
Reminder Light
There is a passenger safety belt
reminder light near the passenger
airbag status indicator. See
Passenger Sensing System 068.

When the vehicle is started, the
passenger airbag status indicator
will light ON and OFF for several
seconds as a system check. Then,
after several more seconds, the
status indicator will light either ON
or OFF to let you know the status of
the front outboard passenger frontal
airbag.
If the word ON is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag is allowed
to inflate.
If the word OFF is lit on the
passenger airbag status indicator, it
means that the passenger sensing
system has turned off the front
outboard passenger frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be aproblem 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. See
Airbag Readiness
Light 0108 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, the Driver
Information Center (DIC) also
displays the SERVICE BATTERY
CHARGING SYSTEM message.
See
Vehicle Messages 0123 for
more information.
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.

includes all the information in
Format One along with a circular
tachometer, but without outside air
temperature.
All formats will show the
Turn-By-Turn navigation information
and provide details about the next
driving maneuver to be made. When
you near your destination, the HUD
will display a distance bar that will

destination. All navigation
information is provided to the HUD
by the navigation radio, if equipped.
Care of the HUD
Clean the inside of the windshield
as needed to remove any dirt or film
that could reduce the sharpness or
clarity of the HUD image. To clean the HUD lens, use a soft,
clean cloth that has household glass
cleaner sprayed on it. Wipe the
HUD lens gently, then dry it. Do not
spray cleaner directly on the lens
because the cleaner could leak into
the unit.
HUD Troubleshooting
Check that:
.
Nothing is covering the
HUD lens.
. HUD brightness setting is not
too dim or too bright.
. HUD is adjusted to the proper
height.
. Polarized sunglasses are
not worn.
. Windshield and HUD lens are
clean.
If the HUD image is not correct,
contact your dealer.
The windshield is part of the HUD
system. See Windshield
Replacement 0230.
Vehicle Messages
Messages are displayed on the DIC
to notify the driver that the status of
the vehicle has changed and that
some action may be needed by the

Some messages may not require
immediate action, but you can press
any of the DIC buttons on the
instrument panel to acknowledge
that you received the messages and
to clear them from the display.
Some messages cannot be cleared
from the DIC display because they
are more urgent. These messages

clearing the messages will only
make the messages disappear, not
correct the problem.
