Instruments and Controls 101The front passenger seat belt
reminder light and chime may turn
on if an object is put on the seat
such as a briefcase, handbag,
grocery bag, laptop, or other
electronic device. To turn off the
reminder light and/or chime, remove
the object from the seat or buckle
the seat belt.
Airbag Readiness Light This light shows if there is an
electrical problem with the airbag
system. The system check includes
the airbag sensor(s), passenger
sensing system, the pretensioners,
the airbag modules, the roll bars,
the wiring, and the crash sensing
and diagnostic module. For more
information on the airbag system,
see Airbag System 0 59 . The airbag readiness light comes on
for several seconds when the
vehicle is started. If the light does
not come on then, have it fixed
immediately.
{ WarningIf the airbag readiness light stays
on after the vehicle is started or
comes on while driving, it means
the airbag system might not be
working properly. The airbags in
the vehicle might not inflate in a
crash, or they could even inflate
without a crash. To help avoid
injury, have the vehicle serviced
right away.
Passenger Airbag Status
Indicator The vehicle has a passenger
sensing system. See Passenger
Sensing System 0 65 for important
safety information. The center stack
has a passenger airbag status
indicator. 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 seconds, the status
indicator will light either ON or OFF
to let you know the status of the
front outboard passenger frontal
airbag and knee airbag.
If the word ON is lit on the
passenger airbag status indicator, it
means that the front outboard
passenger frontal airbag and knee
airbag are 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
and passenger knee airbag.

102 Instruments and Controls If, after several seconds, both status
indicator lights remain on, or if there
are no lights at all, there may be a
problem with the lights or the
passenger sensing system. See
your dealer for service.
{ WarningIf 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 0 101 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 on
with the engine not running. See
Ignition Positions 0 145 .
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.
CautionIf 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.

146 Driving and Operating CautionUsing a tool to force the key to
turn in the ignition could cause
damage to the switch or break the
key. Use the correct key, make
sure it is all the way in, and turn it
only with your hand. If the key
cannot be turned by hand, see
your dealer.

0 148 .
This is the only position from which
the key can be removed. This locks
the ignition and automatic
transmission. Do not turn the engine off when the
vehicle is moving. This will cause a
loss of power assist in the brake
and steering systems and disable
the airbags.
If the vehicle must be shut off in an
emergency:
1. Brake using a firm and steady
pressure. Do not pump the
brakes repeatedly. This may
deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral).
This can be done while the
vehicle is moving. After shifting
to N (Neutral), continue to
firmly apply the brakes and
steer the vehicle to a safe
location.
3. Come to a complete stop. Shift
to P (Park). Turn the
ignition off.
4. Set the parking brake. See
Electric Parking Brake 0 155 .{ WarningTurning off the vehicle while
moving may cause loss of power
assist in the brake and steering
systems and disable the airbags.

2 : The ignition switch stays in this
position when the engine is running.
This position can be used to operate
the electrical accessories, including
the ventilation fan and 12-volt power
outlet, as well as to display some
warning and indicator lights. This
position can also be used for
service and diagnostics, and to
verify the proper operation of the
