NOTE:
• Thin poles or obstacles lower than the sen-
sors may become undetectable as the
vehicle moves closer to them even if they
have been detected from longer distances.
• The system may calculate the distance
to a road sign or similar obstacle to be
shorter than the actual distance.
Obstacle Indication by Parking Sen-
sor
Information display symbol
79MM03031
(1) Obstacle detected by rear center sensors
(2) Obstacle detected by rear corner sensors
Upon detecting an obstacle, the parking
sensor causes an interior buzzer to sound
and a symbol representing the obstacle
appears on the information display in the
instrument cluster (If equipped).
• A different symbol is displayed depend-
ing on the direction and distance of the
obstacle. (If equipped)
• A buzzer located behind the rear seat
sounds when a sensor at the rear
detects an obstacle.
WARNING
• Under the following conditions, the
parking sensor system may not
work normally because the sensors
cannot detect obstacles correctly.
– Sensors are covered with mud,
ice or other materials. (Such
materials must be removed for
normal operation.)
– Sensors are wet from water
splashes or heavy rain.
– Sensors are covered by a hand,
sticker, accessory, etc.
– There is an accessory or other
object attached within the sen-
sor’s sensing area.
– Items such as tow hooks, com-
mercially available corner poles,
radio antenna, etc. are installed
on the bumper.
– The height of the bumper is
changed due to alteration to the
suspension or other causes.
– The sensor areas are extremely
hot from direct sunlight or cold
due to freezing weather.
– The vehicle is on a rough surface,
slope, gravel road or grass field.
– The vehicle is at a steep angle.

WARNING
(Continued)
– Sensors have intercepted ultra-
sonic noise from another vehicle’s
horn, engine, air braking system
(large vehicles), or parking sensor.
– Obstacles are too close to the sen-
sors.
– Sensors are at an angle to a highly
reflective object such as glass.
(Ultrasonic waves are not reflected
back from the obstacle.)
• Sensors may not be able to correctly
detect the following types of obsta-
cles:
– Objects made of a thin material like
wire netting and ropes
– Square-shaped curbstones or
other objects with sharp edges
– Tall objects with a large upper part
like a road sign
– Low-profile objects such as curb-
stones
– Sound-absorbing objects such as
cotton and snow
