OPERATING YOUR VEHICLE
Approximate areas where obstacles can
be detected
Swift
EXAMPLE
74LHT3003
Swift Dzire
EXAMPLE
74LHT3004
• An obstacle within about 20 cm (8 in)
from a sensor or just below a sensor is
not detectable.
• The sensors can detect an obstacle up to
about 1.5 m (5 ft) from the rear of vehicle.
3-27
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 oper-
ation.)
– sensor
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, commer-
cially 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.
– Sensors have intercepted ultrasonic
noise from another vehicle's horn,
engine, air braking system (large vehi-
cles), or parking sensor.
– Obstacles are too close to the sen-
sors.

WARNING
– Sensors are at an angle to a highly
reflective object such as glass. (Ultra-
sonic waves are not reflected back
from the obstacle.)
• Sensors may not be able to correctly
detect the following types of obstacles:
– 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 cot-
ton and snow.
– Sensors have intercepted ultra-
sonic noise from another vehi-
cle's horn, engine, air braking
system (large vehicles), or park-
ing sensor.
– Obstacles are too close to the
sensors.
– 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 cor-
rectly detect the following types of
obstacles:
– Objects made of a thin material
like wire netting and ropes.
– Square-shaped
curbstones
other objects with sharp edges.
