Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly de-
tect an obstacle. Particular instances
where this may occur are listed be-

absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro-
jecting outwards in the direction of

safely and possibly cause an accident.
• Do not use the sensor at speeds in
excess of 6 mph (10 km/h).
• Do not attach any accessories within
the sensor range.
Even though sensors which are func-
tioning properly continue to detect
obstacles, never use the Lexus park-
ing assist if one more sensor(s) may
be malfunctioning.

malfunctioning in the following
cases, have it checked by any autho-
rized Lexus dealer or repairer, or
another duly qualified and equipped
professional.
