{Warning
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon as
it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors
(if equipped with power door locks),
turn on the interior lamps and
hazard warning flashers, and shut
off the fuel system after the airbags
inflate. The feature may also
activate, without airbag inflation, after an event that exceeds a
predetermined threshold. You can
lock the doors, and turn off the
interior lamps and the hazard
warning flashers by using the
controls for those features.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the airbag
system will not be there to help
protect you in another crash.
A new system will include airbag
modules and possibly other
parts. The service manual for
the vehicle covers the need to
replace other parts.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording on page 13-14.
.Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.

3-26 Seats and Restraints
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal, may keep the airbag system
from working properly. The
operation of the airbag system can
also be affected by changing any
parts of the front seats, safety belts,
the airbag sensing and diagnosticmodule, steering wheel, instrument
panel, any of the airbag modules,
ceiling or pillar garnish trim, front
sensors, rollover sensor module,
or airbag wiring.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
If the vehicle has rollover roof-rail
airbags, see
Different Size Tires
and Wheels on page 10-59 for
additional important information.
If you have to modify your vehicle
because you have a disability and
you 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.
See Customer Assistance Offices
on page 13-3.
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 on
page 5-14.
{Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
open or break the airbag
coverings. If there are any
opened or broken airbag
coverings, have the airbag
covering and/or airbag module
replaced. For the location of the
airbags, see Where Are the
Airbags? on page 3-18. See your

Seats and Restraints 3-45
Warning (Continued)
Secure rear-facing child restraints
in a rear seat, even if the airbag
is off. If you secure a
forward-facing child restraint in
the front outboard seat, always
move the front passenger seat as
far back as it will go. It is better to
secure the child restraint in a
rear seat.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. For
example, the front outboard
passenger frontal airbag could
inflate even though the airbag
on-off switch is turned off.(Continued)
Warning (Continued)
To help avoid injury to yourself or
others, have the vehicle serviced
right away. SeeAirbag Readiness
Light on page 5-14 for more
information, including important
safety information.
If the vehicle does not have a rear
seat that will accommodate a
rear-facing child restraint, a
rear-facing child restraint should not
be installed in the vehicle, even if
the airbag is off.
If the child restraint uses a top
tether, see Lower Anchors and
Tethers for Children (LATCH
System) on page 3-35 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 strap
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.
When the airbag off switch has
turned off the front outboard
passenger frontal airbag, the off
indicator in the airbag off light
should light and stay lit when the
vehicle is started. See Airbag
On-Off Light on page 5-15.
2. Put the child restraint on the seat.

.The gauge moves a little while
turning a corner or speeding up.
.The gauge does not go back to
empty when the ignition is
turned off.
If the vehicle has a diesel engine,
see the Duramax diesel
supplement.
Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) or kPa (kilopascals)
when the engine is running.
Oil pressure may vary with engine
speed, outside temperature and oil
viscosity, but readings above the
low pressure zone indicate the
normal operating range.
A reading in the low pressure zone
may be caused by a dangerously
low oil level or other problem
causing low oil pressure.
{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.

Black plate (14,1)GMC Savana Owner Manual (GMNA-Localizing-U.S./Canada-7707482) -
2015 - crc - 6/3/14
5-14 Instruments and Controls
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle for an extended period.
This condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can be only driven for a
short time with the reading in either
warning zone. If it must be driven,
turn off all unnecessary
accessories.
Readings in either warning zone
indicate a possible problem in the
electrical system. Have the vehicle
serviced as soon as possible.Safety Belt Reminders
Safety Belt Reminder Light
There is a safety belt reminder light
on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their safety belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver safety belt is buckled,
neither the light nor the chime
comes on.
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 (if equipped), the
pretensioners (if equipped), the
airbag modules, the wiring, and the
crash sensing and diagnostic
module. For more information on the
airbag system, seeAirbag System
on page 3-16.
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.
