Front air bags may not inflate in side
impact collisions, because occupants
move to the direction of the collision,
and thus in side impacts, frontal air bag
deployment would not provide addi-tional occupant protection. In an angled collision, the force of
impact may direct the occupants in a
direction where the air bags would not
be able to provide any additional bene-
fit, and thus the sensors may not
deploy any air bags. 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 reduced by such “under-ride”
collisions.

D170200AEN Non-operational conditions of rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It willoperate 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 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter. D170300AEN Rear parking assist system pre- cautions
The rear parking assist system may
not sound sequentially depending on the speed and shapes of the objectsdetected.
The rear parking assist system may malfunction if the vehicle bumperheight or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
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.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.
