seat belt, and child restraints is
necessary for most effective
protection. Failure to follow all
instructions in this manual
concerning the use of seats, seat
belts, and child restraints can
increase the risk or severity of
injury in an accident.
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator is
under the climate controls.
After the ignition switch is placed in
the ON position, the passenger
airbag status indicator on the
instrument panel will light for about
seven seconds. When the system
check is complete, the word OFF
and the symbol for off will be visible
if the front outboard passenger
frontal airbag is turned off. See
Passenger Airbag Status Indicator
090.
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.

or not there is an airbag for that
person.
{Warning
If the airbag readiness light ever
comes on and stays on,
or flashes, 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 089
for more information, including
important safety information.
If the Off Indicator Is Not Lit for
a Child Restraint
If a child restraint has been installed
and the off indicator is not lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle. 3. Remove any additional items
from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint following the directions
provided by the child restraint
manufacturer and refer to
Securing Child Restraints 075.
5. If, after reinstalling the child restraint and restarting the
vehicle, the off indicator is still
not lit, turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to make
sure that the vehicle seatback
is not pushing the child
restraint into the seat cushion.
Also make sure the child
restraint is not trapped under
the vehicle head restraint.
If this happens, adjust the head
restraint. See Head Restraints
0 37.
6. Restart the vehicle. If the off indicator is still not lit, do
not install a child restraint in this
vehicle and check with your dealer.
Consider using another vehicle to
transport the child when a rear seat
is not available. Never put a
rear-facing child restraint in the front
seat, even if the off indicator is lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in
the front outboard passenger seat,
but the off indicator is lit, it could be
because that person is not sitting
properly in the seat. Use the
following steps to allow the system

Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the gas
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The indicator moves a little when
turning a corner or speeding up.
. The gauge goes back to empty
when the ignition is turned off.
Seat Belt Reminders
The light and chime remind you to
fasten your seat belts. The light
illuminates when the ignition is
placed in ON or START and remains
illuminated until the driver ’s seat belt
is fastened. At the same time, the
chime sounds for about six seconds
unless the driver ’s seat belt is
securely fastened.
The seat belt warning light may also
illuminate if the front passenger ’s
seat belt is not fastened when the
front passenger seat is occupied.
For seven seconds after the ignition
switch is placed in ON, the system
does not activate the warning light
for the front passenger.
{Warning
If the seat belt warning light stays
on continuously while the ignition
is turned ON with all doors closed
and all seat belts fastened, it may
indicate a malfunction in the
system. Have the system
checked by your dealer.
See Seat Belts 043.
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 wiring, and
the crash sensing and diagnostic
module. For more information on the
airbag system, see Airbag System
0 49.
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.

{Warning
If the airbag readiness light stays
on or comes on and flashes 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

The passenger airbag status
indicator is under the climate
controls.
After the ignition switch is placed in
the ON position, the passenger
airbag status indicator on the
instrument panel will light for about
seven seconds and then go out or
stay lit depending on the front
outboard seat occupied status. The
passenger airbag status indicator
operates as follows:
.Passenger seat occupied by a
small adult, child, or child
restraint: The passenger airbag
status indicator lights to indicate
that the front passenger frontal
airbag is off and will not inflate in
a collision.
. Occupied passenger seat and
the passenger meets the
conditions outlined in this
manual: The passenger airbag
status indicator is not lit to
indicate that the front passenger
frontal airbag is operational.

Charging System Light
This light will come on briefly when
the ignition is turned on, and the
engine is not running, as a check to
show it is working.
It should go out when the engine is
started. If it 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. If a short
distance must be driven with the light on, turn off all accessories,
such as the radio and air
conditioner, to help reduce the drain
on the battery.
Malfunction Indicator
Lamp (Check Engine
Light)
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
ON, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions
0145 for more
information.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the
OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the service technician in
correctly diagnosing any
malfunction.
Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.

Emissions Inspection and
Maintenance Programs
Depending on where you live, your
vehicle may be required to
participate in an emission control
system inspection and maintenance
program. For the inspection, the
emission system test equipment will
likely connect to the vehicle's Data
Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. Connecting devices that are
not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0174. See
your dealer if assistance is needed. The vehicle may not pass
inspection if:
.
The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON while
the engine is off. See your
dealer for assistance in verifying
proper operation of the
malfunction indicator lamp.
. The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II system readiness, your dealer
can prepare the vehicle for
inspection.
Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.

When the ignition is on, the brake
system warning light also comes on
when the parking brake is set. See
Parking Brake0156. The light stays
on if the parking brake does not fully
release. If it stays on after the
parking brake is fully released, it
means the vehicle has a brake
problem.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal might go closer to the
floor. It could take longer to stop.
If the light is still on, check the brake
fluid level and have the vehicle
towed for service. See Towing the
Vehicle 0231.
{Warning
The brake system might not be
working properly if the brake
system warning light is on.

Antilock Brake System
(ABS) Warning Light
MetricEnglish
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes.
If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
