Driving
■ Situations in which the system may not
operate normally
In the following situations, the system may
not operate normally.
● Environmental influence
• There is a static object that cannot be
detected between the vehicle and
another static object that can be
detected
• A static object such as another vehicle, a
motorcycle, a bicycle or a pedestrian cuts
in front of the vehicle or jumps out from
the side.
● Influence from the weather
• The area around the sensor is extremely
hot or cold
• The wind is strong
• Ice, snow, dirt, etc., has adhered to the
sensor (if removed, the system returns to
normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a
sand storm
● Influence from other sonic waves
• An ultrasonic wave source is nearby, such
as the horn or clearance sonar of another
vehicle, a vehicle detector, a motorcycle
engine or the air brake of a large vehicle
• Electronic components (such as a backlit
license plate (especially fluorescent
types), fog lights, a fender pole or a wire-
less antenna) are installed near the sen-
sors
● Changes in the vehicle
• The vehicle is tilted a large amount
• The height of the vehicle has drastically
changed due to the carried load (the
nose tilts up or down)
• The direction of the sensor has deviated
due to a collision or other impact
■ When “Parking Support Brake Unavail-
able” is displayed on the multi-informa-
tion display and the PKSB OFF indicator
flashes
● Ice, snow, dirt, etc., may have adhered to
the sensor. If this occurs, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal.
Also, a warning message may be dis-
played at low temperatures due to ice
forming on the sensor, and the sensor
may not detect static objects. Once the
ice melts, the system will return to normal.
● If this message is shown even after
removing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected by your
Lexus dealer.
● System initialization may not have been
performed after removal and installation
of the battery. Perform system initializa-
tion.
■ When removing and installing the bat-
tery
The system needs to be initialized.
The system can be initialized by driving the
vehicle straight ahead for 5 seconds or
more at a speed of approximately 35 km/h
(22 mph) or higher.
■ When “Parking Support Brake Mal-
function Visit Your Dealer” is displayed
on the multi-information display, the
PKSB OFF indicator flashes and the
buzzer sounds
The system may not be operating properly.
Have the vehicle inspected by your Lexus
dealer.
