92 Seats and Restraints
Warning (Continued)
restraint properly in the vehicle
using the vehicle safety belt or
LATCH system, following the
instructions that came with that
child restraint and the instructions
in this manual.
To help reduce the chance of injury,
the child restraint must be secured
in the vehicle. Child restraint
systems must be secured in vehicle
seats by lap belts or the lap belt
portion of a lap-shoulder belt, or by
the LATCH system. See Lower
Anchors and Tethers for Children
(LATCH System) 094. Children can
be endangered in a crash if the child
restraint is not properly secured in
the vehicle.
When securing an add-on child
restraint, refer to the instructions
that come with the restraint which
may be on the restraint itself or in a
booklet, or both, and to this manual.
The child restraint instructions are important, so if they are not
available, obtain a replacement
copy from the manufacturer.
Keep in mind that an unsecured
child restraint can move around in a
collision or sudden stop and injure
people in the vehicle. Be sure to
properly secure any child restraint in
the vehicle
—even when no child is
in it.
In some areas of the United States
and Canada, Certified Child
Passenger Safety Technicians
(CPSTs) are available to inspect
and demonstrate how to correctly
use and install child restraints. In
the U.S., refer to the National
Highway Traffic Safety
Administration (NHTSA) website to
locate the nearest child safety seat
inspection station. For CPST
availability in Canada, check with
Transport Canada or the Provincial
Ministry of Transportation office.
Securing the Child Within the
Child Restraint
{Warning
A child can be seriously injured or
killed in a crash if the child is not
properly secured in the child
restraint. Secure the child
properly following the instructions
that came with that child restraint.
Where to Put the
Restraint
According to accident statistics,
children and infants are safer when
properly restrained in a child
restraint system or infant restraint
system secured in a rear seating
position.
Whenever possible, children age
12 and under should be secured in
a rear seating position.
If a child restraint is secured in the
front outboard passenger seat, and
the vehicle has a switch on the
passenger side instrument panel
endcap to manually turn off the front

6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the
belt, and feed the shoulder belt
back into the retractor. When
installing a forward-facing child
restraint, it may be helpful to
use your knee to push down on
the child restraint as you
tighten the belt.
Try to pull the belt out of the
retractor to make sure the
retractor is locked. If the
retractor is not locked, repeat
Steps 5 and 6. 7. If the vehicle does not have a
rear seat and the child restraint
manufacturer recommends
using a top tether anchor,
attach the top tether to the top
tether anchor. Refer to the
instructions that came with the
child restraint and to Lower
Anchors and Tethers for
Children (LATCH System) 094.
8. 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.
If the vehicle is equipped with a
passenger sensing system, and
when the passenger sensing system
has turned off the front outboard
passenger frontal airbag, the off
indicator in the passenger airbag
status indicator should light and stay
lit when the vehicle is started. If a child restraint has been installed
and the on indicator is lit, see
“If the
On Indicator Is Lit for a Child
Restraint” underPassenger Sensing
System 080 for more information.
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.
With Airbag On-Off Switch
This vehicle has airbags. A rear
seat is a safer place to secure a
forward-facing child restraint. See
Where to Put the Restraint 092.
There may be a switch on the
instrument panel endcap that you
can use to turn off the front
outboard passenger frontal airbag.
See Airbag On-Off Switch 078 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
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.
See Airbag System
Messages 0158.

If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
(Continued)
Warning (Continued)
example, the front outboard
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.
To help avoid injury to yourself or
others, have the vehicle serviced
right away. SeeAirbag Readiness
Light 0137 for more information,
including important safety
information.
If the word ON or the on symbol is

142 Instruments and Controls
Check the following:
.A loose or missing fuel cap may
cause the light to come on. See
Filling the Tank 0320. A few
driving trips with the cap
properly installed may turn the
light off.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off. See
Fuel 0317.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
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. See Add-On
Electrical Equipment 0349. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running.
. The light does not come on
when the ignition is in ON/RUN
while the engine is off.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.
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
is a brake problem. Have the brake
system inspected right away.
