that the ventilation system al-
ways works properly.
. If at any time you suspect that
exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid or rear gate
closed while driving to prevent
exhaust gas from entering thevehicle. &
Drinking and driving
WARNING
Drinking and then driving is very
dangerous. Alcohol in the blood-
stream delays your reaction time
and impairs your perception, judg-
ment and attentiveness. If you drive
after drinking –even if you drink just
a little –it will increase the risk of
being involved in a serious or fatal
accident, injuring or killing yourself,
your passengers and others. In
addition, if you are injured in the
accident, alcohol may increase the
severity of that injury.
Please don ’t drink and drive.
Drunken driving is one of the most
frequent causes of accidents. Since alco-
hol affects all people differently, you may
have consumed too much alcohol to drive
safely even if the level of alcohol in your
blood is below the legal limit. The safest
thing you can do is never drink and drive.
However if you have no choice but to
drive, stop drinking and sober up comple-
tely before getting behind the wheel. &
Drugs and drivingWARNING
There are some drugs (over the
counter and prescription) that can
delay your reaction time and impair
your perception, judgment and at-
tentiveness. If you drive after taking
them, it may increase your, yourpassengers ’and other persons ’risk
of being involved in a serious or
fatal accident.
If you are taking any drugs, check with
your doctor or pharmacist or read the
literature that accompanies the medication
to determine if the drug you are taking can
impair your driving ability. Do not drive
after taking any medications that can
make you drowsy or otherwise affect your
ability to safely operate a motor vehicle. If
you have a medical condition that requires
you to take drugs, please consult with
your doctor.
Never drive if you are under the influence
of any illicit mind-altering drugs. For your
own health and well-being, we urge you
not to take illegal drugs in the first place
and to seek treatment if you are addicted
to those drugs. 7

tion system is malfunctioning.

1-46Seat, seatbelt and SRS airbags
system may or may not activate the
front passenger ’s SRS frontal airbag
depending on the occupant ’s seating
posture. If the front passenger ’s SRS
frontal airbag is activated (the ON
indicator remains i lluminated while
the OFF indicator turns off), take the
following actions. . Ensure that no article is placed on
the seat other than the occupant. . Ensure that there is no article left in
the seatback pocket.
If the ON indicator still remains illumi-
nated while the OFF indicator turns off
despite the fact that the actions noted
above have been taken, seat the child/
small adult in the rear seat and im-
mediately contact your SUBARU dealer
for an inspection. Even if the system
has passed the dealer inspection, it is
recommended that on subsequent trips
the child/small adult always take the
rear seat.
Children who have outgrown a child
restraint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated. !
Conditions in which front passen-ger’s SRS frontal airbag is activated
The front passenger ’s SRS frontal airbag
will be activated for deployment upon
impact when any of the following condi-
tions are met regarding the front passen- ger ’s seat.
. When the seat is occupied by an adult.
. When a heavy article is placed on the
seat.
CAUTION
When the front passenger ’s seat is
occupied by an adult, observe the
following precautions. Failure to do
so may lessen the load on the frontpassenger ’s seat, deactivating the
front passenger ’s SRS frontal airbag
despite the fact that the seat is
occupied by an adult. This could
result in personal injury. . Do not allow the rear seat occu-
pant to lift the front passenger ’s
seat cushion using his/her feet.
. Do not place any article under the
front passenger ’s seat, or
squeeze any article from behind
and under the seat. This may lift
the seat cushion.
. Do not squeeze any article be- tween the front passenger
’s seat
and side trim/pillar, door or cen-
ter console box. This may lift the
seat cushion.
! If the passenger ’s frontal airbag OFF
indicator illuminates and the ON
indicator turns off even when the
front passenger ’s seat is occupied
by an adult
This can be caused by the adult incor-
rectly sitting in the front passenger ’s seat.
1. Turn the ignition switch to the “LOCK ”
position.
2. Ask the front passenger to set the
seatback to the upright position, sit up
straight in the center of the seat cushion,
correctly fasten the seatbelt, position his/
her legs out forward, and adjust the seat to
the rearmost position.

1-48Seat, seatbelt and SRS airbags
! SRS frontal airbag operation
A) Driver ’s side
B) Passenger ’s side
1) SRS AIRBAGs deploy as soon as a collision occurs.
2) After deployment, SRS AIRBAGs start to deflate immediately so that the driver ’s vision is not
obstructed. The SUBARU advanced frontal airbag
system is designed to determine the
activation or deactivation condition of the
front passenger
’s SRS frontal airbag
depending on the total load on the frontpassenger ’s seat monitored by the front
passenger ’s occupant detection system
weight sensor. For this reason, only thedriver ’s SRS frontal airbag may deploy in
the event of a collision, but this does not
mean failure of the system.
If the front sub sensors and the impact
sensors in the airbag control module
detect a predetermined amount of force
during a frontal collision, the control
module sends signals to the airbag
module(s) (only driver ’s module or both
driver ’s and front passenger ’s modules)
instructing the module(s) to inflate the
SRS frontal airbag(s). The driver ’s and
front passenger ’s SRS frontal airbags use
dual stage inflators.
The two inflators of each airbag are
triggered either sequentially or simulta-
neously, depending on the severity of
impact, in the case of the driver ’s SRS
frontal airbag and depending on the
severity of impact and the total load on
the seat in the case of the front passen-ger ’s SRS frontal airbag.
