2006 SUBARU IMPREZA ignition

Seat, seatbelt and SRS airbags 1-53
– CONTINUED –
Operation
1) SRS side airbag deploys as soon as a
collision occurs.
2) SRS side airbag protects the front pas- senger ’s head and chest.
3) After deployment, SRS side airbag starts to deflate immediately.
The SRS side airbag can function only
when the ignition switch is in the “ON ” po-
sition.
The driver ’s and front passenger ’s SRS
side airbags deploy independently of each
other since each has its own impact sen-
sor. Also, the SRS side airbag deploys in-
dependently of the frontal airbags in the
steering wheel and instrument panel.
An impact sensor is incorporated into
each of the vehicle ’s center pillars. If ei-
ther sensor detects a certain predeter-
mined amount of force during a side im-
pact collision, the control module sends a
signal to the side airbag module on the im-
pacted side of the vehicle, instructing it to
inflate the SRS side airbag. Then the side
airbag module produces gas, which in-
stantly inflates the SRS side airbag. After
deployment, the SRS side airbag will de-
flate in a few seconds.
The SRS side airbag deploys even when
no one occupies the seat on the side on
which an impact is applied.
When the SRS side airbag deploys, a sud-
den, fairly loud inflation noise will be heard
and some smoke will be released. These
occurrences are normal result of the de-
ployment. This smoke does not indicate a
fire in the vehicle.
Do not put any kind of cover or
clothes or other objects over either
front seatback and do not attach la-
bels or stickers to the front seat sur-
face on or near the SRS side airbag.
They could prevent proper deploy-
ment of the SRS side airbag, reduc-
ing protection available to the front
seat ’s occupant.

SRS airbag system servicing
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury.
Flashing or flickering of the warn-
ing light
No illumination of the warning
light when the ignition switch is
first turned to the “ON ” position
Continuous illumination of the
warning light
Illumination of the warning light
while driving
When discarding an airbag mod-
ule or scrapping the entire vehicle
damaged by a collision, consult
your SUBARU dealer.
The SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal test equipment on any circuit
related to the SRS airbag system.
For required servicing of the SRS
airbag, see your nearest SUBARU
dealer. Tampering with or discon-
necting the system ’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.

Immobilizer (Turbo models)
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle ’s immobilizer system
can be used to operate your vehicle. Even
if an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a tran-
sponder in which the key ’s ID code is
stored. When a key is inserted into the ig-
nition switch and turned to the “ON ” posi-
tion, the transponder transmits the key ’s
ID code to the immobilizer system ’s re-
ceiver. If the transmitted ID code matches
the ID code registered in the immobilizer
system, the system allows the engine to
be started. Since the ID code is transmit-
ted and acted upon almost instantly, the
immobilizer system does not impede nor-
mal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. (Refer to the “Ig-
nition switch ” section [chapter 3].)
This device complies with Part 15 of
the FCC Rules and with RSS-210 of In-
dustry Canada. Operation is subject to
the following two conditions: (1) This device may not cause harmful interfer-
ence, and (2) this device must accept
any interference received, including in-
terference that may cause undesired
operation.
Changes or modifications not express-
ly approved by the party responsible
for compliance could void the user
’s
authority to operate the equipment.
NOTE
To protect your vehicle from theft,
please pay close attention to the fol-
lowing security precautions:
Never leave your vehicle unattended
with its keys inside.
Before leaving your vehicle, close all
windows and lock the doors and rear
gate.
Do not leave spare keys or any
record of your key number in the vehi-
cle.
Security ID plate
1) Key number plate
2) Security ID plate
The security ID is stamped on the metal
plate attached to the key set. Write down
the security ID and keep it in another safe
place, not in the vehicle. This number is
needed to make a replacement key if you
lose your key or lock it inside the vehicle.
This number is also needed for replace-
ment or repair of the engine control unit,
immobilizer control unit.
Security indicator light
The security indicator light deters potential
thieves by indicating that the vehicle is
equipped with an immobilizer system. It
Do not place the key under direct
sunlight or anywhere it may be-
come hot.
Do not get the key wet. If the key
gets wet, wipe it dry with a cloth
immediately.

begins flashing (approximately once every
three seconds) approximately 60 seconds
after the ignition switch is turned from the“ON ” position to the “ACC ” or “LOCK ” po-
sition or immediately after the key is pulled
out.
If the security indicator light does not
flash, the immobilizer system may be
faulty. If this occurs, we recommend that
you contact your SUBARU dealer as soon
as possible.
In case an unauthorized key is used (e.g.
an imitation key), the security indicator
light comes on.
NOTE
Even if the security indicator light
flashes irregularly or its fuse blows
(the light does not flash if its fuse is
blown), the immobilizer system will
function normally.
Key replacement
Your key number and security ID will be
required if you ever need a replacement
key made. Any new key must be regis-
tered for use with your vehicle ’s immobiliz-
er system before it can be used. Up to four
keys can be registered for use with one
vehicle.
For security, all the keys registered with your vehicle
’s immobilizer system will
have their ID codes erased and re-regis-
tered when a new key is made. Therefore,
all of your vehicle ’s keys must be present-
ed when a new key is registered. Any key
that is not re-registered when a new key is
made cannot be used after the other keys
are re-registered. For information on re-
placement keys and on the registration of
keys with your immobilizer system, con-
tact your SUBARU dealer.

Keep all doors locked when you
drive, especially when small chil-
dren are in your vehicle.
Along with the proper use of seat-
belts and child restraints, locking
the doors reduces the chance of be-
ing thrown out of the vehicle in an
accident.
It also helps prevent passengers
from falling out if a door is acciden-
tally opened, and intruders from un-
expectedly opening doors and en-
tering your vehicle.
