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)(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.
ESC operation

ON, ESC and ESC OFF indi-
cator lights illuminate for

turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
you may hear a slight ticking
sound. This is the ESC per-

cate a problem.
When operating

Driving your vehicle
✽
✽NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect ABS or brake system operation.
The rear parking assist system assists
the driver during backward movement of
the vehicle by chiming if any object is
sensed within a distance of 120 cm (47
in.) behind the vehicle. This system is a
supplemental system and it is not intend-
ed to nor does it replace the need for
extreme care and attention of the driver.
The sensing range and objects
detectable by the back sensors are limit-
ed. Whenever backing-up, pay as much
attention to what is behind you as you
would in a vehicle without a rear parking
assist system.
WARNING
Never press the ESC OFF button
while ESC is operating.
If the ESC is turned off while ESC is
operating, the vehicle may go out of
control.
To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
REAR PARKING ASSIST SYSTEM (IF EQUIPPED)
WARNING
The rear parking assist system is a
supplementary function only. The
operation of the rear parking assist
system can be affected by several
factors (including environmental
conditions). It is the responsibility
of the driver to always check the
area behind the vehicle before
backing up.

Operation of the rear parking
assist system
Operating condition
This system will activate when backing
up with the ignition key ON.
If the vehicle is moved at speed over
5 km/h (3 mph), the system may not
activated correctly.
The sensing distance while the rear parking assist system is in operation is
approximately 120 cm (47 in.).
When more than two objects are sensed at the same time, the closest
one will be recognized first.
Types of warning sound
When an object is 120 cm to 81 cm (47in. to 32 in.) from the rear bumper :
Buzzer beeps intermittently
When an object is 80 cm to 41 cm (31 in. to 16 in.) from the rear bumper :
Buzzer beeps more frequently
When an object is within 40 cm (15 in.) of the rear bumper : Buzzer sounds
continuously.
Non-operational conditions of
rear parking assist system
Rear 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.
