64 Seats and Restraints
{Warning
If something is between an
occupant and an airbag, the
airbag might not inflate properly
or it might force the object into
that person causing severe injury
or even death. The path of an
inflating airbag must be kept
clear. Do not put anything
between an occupant and an
airbag, and do not attach or put
anything on the steering wheel
hub or on or near any other
airbag covering.
Do not use seat accessories that
block the inflation path of a
seat-mounted side impact airbag.
Never secure anything to the roof
of a vehicle with roof-rail airbags
by routing a rope or tie‐down
through any door or window
opening. If you do, the path of an
inflating roof-rail airbag will be
blocked.
When Should an Airbag
Inflate?
This vehicle is equipped with one or
more airbags. SeeAirbag System
0 60. Airbags are designed to inflate
if the impact exceeds the specific
airbag system's deployment
threshold. Deployment thresholds
are used to predict how severe a
crash is likely to be in time for the
airbags to inflate and help restrain
the occupants. The vehicle has
electronic sensors which help the
airbag system determine the
severity of the impact. Deployment
thresholds can vary with specific
vehicle design.
Frontal airbags are designed to
inflate in moderate to severe frontal
or near-frontal crashes to help
reduce the potential for severe
injuries mainly to the driver or front
outboard passenger head and
chest.
Whether the frontal airbags will or
should deploy is not based primarily
on how fast the vehicle is traveling. It depends largely on what you hit,
the direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or
moving, rigid or deformable, narrow
or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, rear
impacts, or in many side impacts.
Seat-mounted side impact airbags,
if equipped, are designed to inflate
in moderate to severe side crashes
depending on the location of the
impact. Seat-mounted side impact
airbags are not designed to inflate in
frontal impacts, near-frontal impacts,
rollovers, or rear impacts.
A seat-mounted side impact airbag
is intended to inflate on the side of
the vehicle that is struck.
The vehicle may or may not be
equipped with roof-rail airbags.
Roof-rail airbags are designed to
inflate in moderate to severe side

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
Publication Ordering Information
0
344.
{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.
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,
including improperly repairing or
replacing, any parts of the following:
.
Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
. Front seats, including stitching,
seams or zippers
. Seat belts
. Steering wheel, instrument
panel, ceiling trim, or pillar
garnish trim
. Inner door seals, including
speakers
Your dealer and the service manual
have information about the location
of the airbag modules and sensors,

Caution
Leaving electrical equipment
plugged in for an extended period
of time while the vehicle is off will
drain the battery. Always unplug
electrical equipment when not in
use and do not plug in equipment
that exceeds the maximum
20 amp rating.
When adding electrical equipment,
be sure to follow the proper
installation instructions included with
the equipment. See Add-On
Electrical Equipment 0227.
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.
Power Outlet 110/120 Volt
Alternating Current
This power outlet can be used to
plug in electrical equipment that
uses a maximum limit of 150 watts.
The 110/120 volt power outlet is on
the instrument panel.
An indicator light on the outlet turns
on to show it is in use. The light
comes on when the ignition is on,
equipment requiring less than 150
watts is plugged into the outlet, and
no system fault is detected.
The indicator light does not come on
when the ignition is off, or if the
equipment is not fully seated into
the outlet.
If equipment is connected using
more than 150 watts or a system
fault is detected, a protection circuit
shuts off the power supply and the
indicator light turns off. To reset the
circuit, unplug the item and plug it
back in or turn the Retained
Accessory Power (RAP) off and
then back on. See Retained
Accessory Power (RAP) 0180. The power outlet is not designed for
the following, and may not work
properly if they are plugged in:

Instruments and Controls 105
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, the
gauge shows the condition of the
charging system. 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
at an idle for an extended period.This condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can be only driven for a
short time with the reading in either
warning zone. If it must be driven,
turn off all unnecessary
accessories.
Readings in either warning zone
indicate a possible problem in the
electrical system. Have the vehicle
serviced as soon as possible.
Seat Belt Reminders
Seat Belt Reminder Light
There is a seat 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 seat 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 seat belt is buckled,
neither the light nor the chime
comes on.
Airbag Readiness Light
This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), the

Lighting 127
Daytime Running
Lamps (DRL)
DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional DRL are
required on all vehicles first sold in
Canada.
The DRL system comes on in
daylight when the following
conditions are met:
.The ignition is on.
. The exterior lamp control is in
the AUTO position.
. The shift lever is not in P (Park).
. The light sensor determines it is
daytime.
When the DRL are on, the taillamps,
sidemarker, instrument panel lights,
and other lamps will not be on.
The automatic headlamp system
automatically switches from DRL to
the headlamps depending on the
darkness of the surroundings. To turn off the DRL, turn the exterior
lamp control to
Oand then release
it. For vehicles first sold in Canada,
the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp
System
When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps, along with
the taillamps, sidemarker lamps,
parking lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamp
control to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.The vehicle has a light sensor on
the top of the instrument panel. Do
not cover the sensor; otherwise the
system will come on whenever the
ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system are only affected
when the light sensor sees a
change in lighting lasting longer
than the delay.
