Warning (Continued)
using another vehicle to transport
the child when a rear seat is not
available.
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag if:
. The front outboard passenger seat
is unoccupied.
. The system determines an infant
is present in a child restraint.
. A front outboard passenger takes
his/her weight off of the seat for a
period of time.
. There is a critical problem with
the airbag system or the passenger
sensing system.
When the passenger sensing system
has turned off the front outboard
passenger frontal airbag and knee
airbag, the OFF indicator will light and
stay lit as a reminder that the airbags
are off. See Passenger Airbag Status
Indicator 0132. The passenger sensing system is
designed to turn on the front
outboard passenger frontal airbag and
knee airbag, anytime the system
senses that a person of adult size is
sitting properly in the front outboard
passenger seat.
When the passenger sensing system
has allowed the airbag to be enabled,
the ON indicator will light and stay lit
as a reminder that the airbags are
active.
For some children, including children
in child restraints, and for very small
adults, the passenger sensing system
may or may not turn off the front
outboard passenger frontal airbag and
knee airbag, depending upon the
person's seating posture and body
build. Everyone in the vehicle who has
outgrown child restraints should wear
a seat belt properly
—whether or not
there is an airbag for that person.
{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 0131 for
more information, including
important safety information.
If the On Indicator Is Lit for a
Child Restraint
The passenger sensing system is
designed to turn off the front
outboard passenger frontal airbag and
knee airbag, if the system determines
that an infant is present in a child
restraint. If a child restraint has been
installed and the ON indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.

Warning (Continued)
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.
SeePassenger Sensing System 087
for additional information.
If the child restraint uses a top tether,
see Lower Anchors and Tethers for
Children (LATCH System) 099 for top
tether anchor locations.
Do not secure a child seat in a
position without a top tether anchor if
a national or local law requires that
the top tether be anchored, or if the
instructions that come with the child
restraint say that the top tether must
be anchored.
In Canada, the law requires that
forward-facing child restraints have a
top tether, and that the tether be
attached. When using the lap-shoulder belt to
secure the child restraint in this
position, follow the instructions that
came with the child restraint and the
following instructions:
1. Move the seat as far back as it will go before securing the
forward-facing child restraint.
Move the seat upward or the
seatback to an upright position,
if needed, to get a tight
installation of the child restraint.
When the passenger sensing
system has turned off the front
outboard passenger frontal and
knee airbag, the off indicator on
the passenger airbag status
indicator should light and stay lit
when you start the vehicle. See
Passenger Airbag Status Indicator
0132.
2. Put the child restraint on the seat.
3. Pick up the latch plate, and run the lap and shoulder portions of
the vehicle's seat belt through or around the restraint. The child
restraint instructions will show
you how.
4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle, away from the child
restraint, so that the seat belt
could be quickly unbuckled if
necessary.

Warning Lights, Gauges,
and Indicators
Warning lights and gauges can signal
that something is wrong before it
becomes serious enough to cause an
expensive repair or replacement.
Paying attention to the warning lights
and gauges could prevent injury. Some warning lights come on briefly
when the engine is started to indicate
they are working. When one of the
warning lights comes on and stays on
while driving, or when one of the
gauges shows there may be a problem,
check the section that explains what
to do. Waiting to do repairs can be
costly and even dangerous.

{Warning
If 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.
If there is a problem with the airbag
system, a Driver Information Center
(DIC) message may also come on.
Passenger Airbag Status
Indicator
The vehicle has a passenger sensing
system. See Passenger Sensing System
0 87 for important safety information.
The overhead console 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
more 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 knee
airbag. 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.{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

Brake System Warning
Light
The vehicle brake system consists of
electronically controlled hydraulic
brake circuits. If a fault is detected,
valves are adjusted to allow the brake
pedal to push brake fluid directly into
the hydraulic brake circuits. When a
fault occurs, the brake system warning
light comes on, and Driver
Information Center (DIC) messages
may display. Vehicle speed may also
be limited and the amount of brake
pedal force applied may need to
increase. Have the vehicle brake
system serviced as soon as possible.
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 if there is a
problem.
The brake system warning light may
also come on when the parking brake
is set, if the vehicle has low brake
fluid, or if the brakes are severely
faded. See Brake Fluid 0268. If the
brakes are overheated, DIC messages
may display, and the vehicle speed
may be limited. If the brake fluid is
not low, if the brakes are not
overheated, and if the parking brake is
fully released, then the vehicle has a
brake problem. Have the vehicle brake
system serviced as soon as possible. If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal may go closer to the
floor. It could take longer to stop.
If the light is still on, have the vehicle
towed for service. See
Towing the
Vehicle 0312.
{Warning
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning light
on can lead to a crash. If the light is
still on after the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed for
service.
