Vehicle Security
This vehicle has theft-deterrent
features; however, they do not make
it impossible to steal.
Immobilizer
SeeRadio Frequency Statement on
page 13‑16 for information
regarding Part 15 of the Federal
Communications Commission (FCC)
rules and Industry Canada
Standards RSS-GEN/210/220/310.
Immobilizer Operation
This vehicle is equipped with the
PASS-Key®III+ (Personalized
Automotive Security System)
theft-deterrent system.
PASS-Key III+ is a passive
theft deterrent system. The system is automatically armed
when the key is removed from the
ignition.
You do not have to manually arm or
disarm the system.
The security light will come on if
there is a problem with arming or
disarming the theft-deterrent
system.
When the PASS-Key III+ system
senses that someone is using the
wrong key, it shuts down the
vehicle's starter and fuel systems.
The starter will not work and fuel will
stop being delivered to the engine.
Anyone using a trial-and-error
method to start the vehicle will be
discouraged because of the high
number of electrical key codes.
If the engine does not start and the
security message comes on, the
key may have a damaged
transponder. Turn the ignition off
and try again.If the engine still does not start, and
the key appears to be undamaged,
try another ignition key. At this time,
you may also want to check the
instrument panel PASS KEY fuse.
If the engine still does not start with
the other key, the vehicle needs
service. If the vehicle does start, the
first key may be faulty. See your
dealer or a locksmith who can
service the PASS-Key III+ to have a
new key made. See
Fuses and
Circuit Breakers on page 10‑43.
It is possible for the PASS-Key III+
decoder to learn the transponder
value of a new or replacement key.
Up to 10 keys may be programmed
for the vehicle. This procedure is for
learning additional keys only. If all
the currently programmed keys are
lost or do not operate, you must see
your dealer or a locksmith who can
service PASS-Key III+ to have keys
made and programmed to the
system.

Black plate (14,1)GMC Savana Owner Manual - 2012 - 2nd - 11/11/11
2-14 Keys, Doors, and Windows
See your dealer or a locksmith who
can service PASS-Key III+ to get a
new key blank that is cut exactly as
the ignition key that operates the
system.
To program the new key:
1. Verify the new key has
1
stamped on it.
2. Insert the original, already programmed key into the ignition
lock cylinder and start the
engine. If the engine will not
start, see your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF and
remove the key. 4. Insert the key to be programmed
and turn it to ON/RUN within
10 seconds of removing the
previous key.
The security message will turn
off once the key has been
programmed. It may not be
apparent that the security
message went on due to how
quickly the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to be
programmed.
If you lose or damage a
PASS-Key III+ key, see your dealer
or a locksmith who can service
PASS-Key III+ to have a new
key made.
Do not leave the key or device that
disarms or deactivates the
theft-deterrent system in the vehicle.
Exterior Mirrors
Convex Mirrors
{WARNING
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you
cut too sharply into the right lane,
you could hit a vehicle on the
right. Check the inside mirror or
glance over your shoulder before
changing lanes.
The passenger side mirror is convex
shaped. A convex mirror's surface is
curved so more can be seen from
the driver seat.

3-12 Seats and Restraints
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt. If you are
using a rear seating position with a
detachable safety belt and the
safety belt is not attached, see
“Reinstalling the Rear Seats”under
Rear Seats on page 3‑5 for
instructions on reconnecting the
safety belt to the mini-buckle.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”
in the Index. 2. Pick up the latch plate and pull
the belt across you. Do not let it
get twisted.
The lap-shoulder belt may lock if
you pull the belt across you very
quickly. If this happens, let the
belt go back slightly to unlock it.
Then pull the belt across you
more slowly.
If the shoulder portion of a
passenger belt is pulled out all
the way, the child restraint
locking feature may be engaged.
If this happens, let the belt go
back all the way and start again.
3. Push the latch plate into the
buckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑17.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.

Safety Belt Use During
Pregnancy
Safety belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to
be seriously injured if they do not
wear safety belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap
portion should be worn as low as
possible, below the rounding,
throughout the pregnancy.The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
Safety Belt Extender
If the vehicle's safety belt will fasten
around you, you should use it.
But if a safety belt is not long
enough, your dealer will order you
an extender. When you go in to
order it, take the heaviest coat you
will wear, so the extender will be
long enough for you. To help avoid
personal injury, do not let someone
else use it, and use it only for the
seat it is made to fit. The extender
has been designed for adults. Never
use it for securing child seats. To
wear it, attach it to the regular safety
belt. For more information, see the
instruction sheet that comes with
the extender.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer
to have it repaired. Torn or frayed
safety belts may not protect you in a
crash. They can rip apart under
impact forces. If a belt is torn or
frayed, get a new one right away.
Make sure the safety belt reminder
light is working. See
Safety Belt
Reminders on page 5‑16.
Keep safety belts clean and dry.
See Safety Belt Care on page 3‑18.

Black plate (20,1)GMC Savana Owner Manual - 2012 - 2nd - 11/15/11
3-20 Seats and Restraints
{WARNING
Airbags inflate with great force,
faster than the blink of an eye.
Anyone who is up against, or very
close to, any airbag when it
inflates can be seriously injured
or killed. Do not sit unnecessarily
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag
when it inflates can be seriously
injured or killed. Airbags plus
lap-shoulder belts offer protection
for adults and older children, but
not for young children and infants.
Neither the vehicle safety belt
system nor its airbag system is
designed for them. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in the
vehicle. To read how, seeOlder
Children on page 3‑38 orInfants
and Young Children on
page 3‑40.
There is an airbag readiness light
on the instrument panel, which
shows the airbag symbol.
The system checks the airbag
electrical system for malfunctions.
The light tells you if there is an
electrical problem. See Airbag
Readiness Light on page 5‑16 for
more information.
