Reverse park assist limitations
Reverse Park Assist system is not a colli-
sion avoiding system. It is solely the
driver's responsibility to park the vehicle
safely.
Reverse Park Assist feature works on ul-
tra sound echo technology, due to which
performance is not guaranteed in follow-
ing scenarios:
 If the object has a sharp edge sur-
face, where surface may divert ech-
oes from sensor reception.
 If object is mesh fence made up of
thin wires, where echoes can't be
given by the surface.
 Fast moving objects passes in the
sensor's field of detection, where
echoes are not processed by the sys-
tem.
 If object is made/covered by foam or
sponge or snow where ultrasonic
sound signals are absorbed.
 Objects close to the rear bumper can
go undetected by the Reverse Park
Assist's field of detection. Driver
should use extreme caution while
parking the vehicle.
 If height of the bumper is changed
due to alteration to the suspension or
other causes
 If the sensor areas are extremely hot
from direct sunlight or cold due to
freezing weather.
 If Sensors are covered by a hand,
sticker, accessory, etc.
 If ultrasonic noise is present around
Vehicle due to other vehicle sensors,
horn, engine, air braking system
(large vehicles), Exhaust Fans, Wire-
less transmitters or mobile phones
 If
the vehicle speed
10kmph, the system will not warn
you even though objects are de-
tected, error message 'Vehicle Speed
is high, drive slowly!' will appear.
STARTING AND DRIVING
 Driving on uneven road surfaces e.g.
Gravel, unpaved roads, Artificial
Speed Breakers, or gradient.
 Poles of square/rectangular cross
section might not be detected due to
the ultrasonic technology limitation.
Due to any reason, if the sensor gets
misaligned or loses its intended fit-
ment position, contact your dealer
for refitment.
Turning the ignition 'OFF' 'while the
park assist feature is active would
disable it.
