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)

■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.

Driving
■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
(At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system or Multi-terrain Moni-
tor is in use, the warning indicator will appear in the upper corner of the screen even if the
display setting has been set to off.
■Sensor detectio n information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surrounding environment may affect the ability of a
sensor to correctly detect an obstacle. Pa rticular instances where this may occur are
listed below.
• There is dirt, snow or ice on the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor re ceives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there ar e instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

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.

Winter driving tips
●Use fluids that are appropriate to
the prevailing outside temperatures.
•Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
Ensure that all tires are the same size and br and, and that chains match the size of the
tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to me lt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the c limate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassi s, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Carry out the necessary preparations an d inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
