SEATS AND RESTRAINTS 91
Warning (Continued)
Never put a rear-facing child
restraint in the front seat, even if
the airbag is off. If securing a
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 child
restraints in the rear seat. Consider
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 that 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 0138.
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(s) to be enabled, the ON
indicator will light and stay lit as a
reminder that the airbag(s) 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 0138 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.

If the vehicle must be modified
because you have a disability and have
questions about whether the
modifications will affect the vehicle's
airbag system, or if you have
questions about whether the airbag
system will be affected if the vehicle is
modified for any other reason, call
Customer Assistance. SeeCustomer
Assistance Offices 0403.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See Airbag
Readiness Light 0138.
Caution

the location of the airbags, see
Where Are the Airbags?085. See
your dealer for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible. If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
Airbag Readiness Light
0138.

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.

English, Standard Theme Shown
The engine oil pressure gauge shows
the engine oil pressure
in kPa (kilopascals) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature and oil
viscosity.
On some models, the oil pump will
vary engine oil pressure according to
engine needs. Oil pressure may change
quickly as the engine speed or load
varies. This is normal.
If the oil pressure warning light or
Driver Information Center (DIC)
message indicates oil pressure outside the normal operating range, check the
vehicle's oil as soon as possible. See
Engine Oil
0299.
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check the
oil level as soon as possible. Add oil
if required, but if the oil level is
within the operating range and the
oil pressure is still low, have the
vehicle serviced. Always follow the
maintenance schedule for changing
engine oil.
