Features of your vehicle100 3 Just before impact, drivers often brake
heavily. 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 replaced by such “under-ride”
collisions. Air bags may not inflate in rollover acci-
dents because air bag deployment
would not provide 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 impact air bags and
curtain 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.

Driving your vehicle26 4Non-operational conditions of
back warning systemThe back warning system may not
operate properly when:1. Moisture is frozen to the sensor. (It will
operate normally when the moisture
has been cleared.)
2. The sensor is covered with foreign
matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally 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. The sensor is covered with snow.
8. Trailer towing
The detecting range may decrease
when:1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely
hot or cold.The following objects may not be rec-
ognized by the sensor:1. Sharp or slim objects such as ropes,
chains or small poles.
2. Objects which tend to absorb the sen-
sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 40 in.
(1 m) and narrower than 6 in. (14 cm) in
diameter.
CAUTION
1. The back warning may not sound
sequentially depending on the
speed and shapes of the objects
detected.
2. The back warning system may
malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment
or accessories may also interfere
with the sensor performance.
3. The sensor may not recognize
objects less than 15 in. (40 cm)
from the sensor, or it may sense
an incorrect distance. Use cau-
tion.
4. When the sensor is frozen or
stained with snow, dirt, or water,
the sensor may be inoperative
until the stains are removed
using a soft cloth.
5. Do not push, scratch or strike the
sensor. Sensor damage could
occur.
