GX460_OM_OM60T19U_(U)4-1. Before driving
●Avoid jerky starts or sudden acceleration.
●Avoid jerky steering and sharp turns, an
d slow down before making a turn.
●Note that when making a turn, the trailer wheels will be closer than the vehicle
wheels to the inside of the turn. Compensate by making a wider than normal
turning radius.
●Slow down before making a turn, in crosswinds, on wet or slippery surfaces,
etc.
Increasing vehicle speed can destabilize the trailer.
●Take care when passing other vehicles . Passing requires considerable dis-
tance. After passing a vehicle, do not fo rget the length of your trailer, and be
sure you have plenty of room before changing lanes.
●To maintain engine braking efficien cy and charging system performance
when using engine braking, do not put the transmission in D.
If in the S mode, the transmission shift range position must be in 5 or lower.
●Instability happens more frequently when descending steep or long downhill
grades. Before descending, slow down and downshift. Do not make sudden
downshifts while descending st eep or long downhill grades.
●Avoid holding the brake pedal down too long or applying the brakes too fre-
quently. This could cause the brakes to overheat and result in reduced braking
efficiency.
●Due to the added load of the trailer, yo ur vehicle’s engine may overheat on hot
days (at temperatures over 85°F [30°C]) when driving up a long or steep
grade. If the engine coolant temperat ure gauge indicates overheating, imme-
diately turn off the air conditioning (if in use), pull your vehicle off the road and
stop in a safe spot. ( P. 553)

GX460_OM_OM60T19U_(U)4-5. Using the driving support systems
■If a warning message is displayed
on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in the system
●In the following situations, perform the acti ons specified in the table. When the normal
operating conditions are detected, the message will disappear and the system will
become operational.
If the message does not disappear, contact your Lexus dealer.
●In the following situations, if the situatio n has changed (or the vehicle has been driven
for some time) and the normal operating conditions are detected, the message will dis-
appear and the system w ill become operational.
If the message does not disappear, contact your Lexus dealer.
• When the temperature around the radar sens or is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when
driving in the dark, snow, or fog, or when bright lights are shining into the front cam-
era
SituationActions
When the area around a sensor is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or othe r foreign matterTo clean the part of the windshield in front of
the front camera, use the windshield wipers or
the windshield defogger of the air conditioning
system (P. 388).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as after the vehi-
cle had been parked in the sun, use the air con-
ditioning system to de crease the temperature
around the front camera.
If a sunshade was used when the vehicle was
parked, depending on its type, the sunlight
reflected from the surface of the sunshade
may cause the temperature of the front cam-
era to become excessively high.
If the front camera is cold, such after the vehicle
is parked in an extremely cold environment, use
the air conditioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, su ch as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker, etc. to
clear the obstruction.

GX460_OM_OM60T19U_(U)4-5. Using the driving support systems
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular atten-
tion to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi
als that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction of your vehi-
cle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detect ion may be impossible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility th at the obstacle will come within the sensor’s detection
areas before the display is shown and the buzzer sounds.
• Thin posts or objects lower than the sens or may not be detected when approached,
even if they have been detected once.
• It might be difficult to hear beeps due to th e volume of audio system or air flow noise
of the air conditioning system.
■If “Clean Park Sonar”/“Clean Parking Assist Sensor” is displayed on the multi-informa-
tion display
A sensor may be dirty or covered with snow or ic e. In such cases, if it is removed from the
sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction display may
appear or an obstacle may no t be detected. If the sensor thaws out, the system should
return to normal.
■If “Check Park Sonar System”/ “Parking Assist Malfunction” is displayed on the multi-
information display
Depending on the malfunction of the sensor, the device may not be working normally.
Have the vehicle inspected by your Lexus dealer.
■Certification for the intuitive parking assist (Canada only)
This ISM device complies with Canadian ICES-001.
■Customization
Settings (e.g. buzzer sounds volume) can be changed.
