Air bag system components The main components of your SRS are:
To indicate that your vehicle is
equipped with air bags, the corre-
sponding air bag covers are marked
with “SRS AIR BAG”.
- Driver’s air bag
- Passenger’s air bag
- Side air bag
- Curtain air bag
A diagnostic system that continually monitors the system operation.
An indicator light to warn you of a pos- sible problem with the system. Emergency power backup in case your
car’s electrical system is disconnected
in a crash.
The SRS uses a collection of sensors to
gather information about the driver’s seat
position, the driver’s and front passenger’s
safety belt usage and impact severity.
The driver’s seat position sensor, which
is installed on the seat track, determine if
the seat is fore or aft of a reference posi-
tion. Similarly, the safety belt usage sen-
sors determine if the driver and front pas-
senger’s safety belts are fastened. These
sensors provide the ability to control the
SRS deployment based on how close the
driver’s seat is to the steering wheel,
whether or not the safety belts are fas-
tened, and the severity of the impact.
(Continued)
If the driver brakes the vehicle heavily prior to an impact, unbelt-
ed occupants will be thrown for-
ward. If the front passenger is not
wearing the safety belts, they will
be directly in front of the storage
compartment when deployment
occurs. In that situation, serious
injury or death is possible.
Never allow front passenger to put their hands, feet or face on or
close to the instrument panel. In
the event of air bag deployment,
such a mispositioned occupant
would be likely to suffer severe
injury or death.
Never allow children, pregnant women or weak persons to sit in
the front passenger seat. Do not
put child restraint system on the
front passenger's seat either.
They may be seriously injured by
the air bag inflation when air bag
deploys.

(Continued)
Do not put objects or stickers onthe instrument panel. Do not
apply any accessory to the front
windshield. Do not install after-
market mirrors or accessories on
the factory-installed rearview mir-
ror. Any of these could interfere
with the deployment of the air bag
or could hit your body at high
speed and cause severe bodily
injury and even death.

Features of your vehicle
Just before impact, drivers often brakeheavily. Such heavy braking lowers the
front portion of the vehicle causing it to
“ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this "under-ride" situation
because deceleration forces that are
detected by sensors may be signifi-
cantly altered by such “under-ride” col-
lisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide proper protection to
the occupants.
However, side air bags may inflate when the vehicle is rolled over by a
side impact collision, if the vehicle is
equipped with side air bags and cur-
tain air bags. Air bags may not inflate if the vehicle
collides with objects such as utility
poles or trees, where the point of
impact is concentrated to one area and
the full force of the impact is not deliv-
ered to the sensors.

The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.

cator lights illuminate for

will illuminate). To turn the
ESC on, press the ESC OFF

Non-operational conditions of
rear parking assist systemRear parking assist system may notoperate normally when:1. Moisture is frozen to the sensor. (It will operate normally when moisture
melts.)
2. Sensor is covered with foreign matter, such as snow or water, or the sensor
cover is blocked. (It will operate nor-
mally when the material is removed or
the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-
ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. Sensor is covered with snow.
8. Trailer towing
Detecting range may decrease when:1. Sensor is stained with foreign matter such as snow or water. (Sensing range
will return to normal when removed.)
2. Outside air temperature is extremely hot or cold.Following objects may not be recog-nized by the sensor:1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb sensor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) and narrower than 14 cm (6 in.)
in diameter.
CAUTION
1. The rear parking assist system may not sound sequentiallydepending on the speed andshapes of the objects detected.
2. The rear parking assist system may malfunction if the vehiclebumper height or sensor installa- tion has been modified or dam-aged. Any non-factory installedequipment or accessories may also interfere with the sensor per-formance.
3. Sensor may not recognize objects less than 40 cm (15 in.)from the sensor, or it may sensean incorrect distance. Use cau- tion.
4. When sensor is frozen or stained with snow, dirt, or water, sensormay be inoperative until the stains are removed using a softcloth.
5. Do not push, scratch or strike the sensor. Sensor damage couldoccur.
