Driving
●After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not shifted.
Make sure the tongue weight is appropriate, if possible.
• Check the load in the vehicle. Make sure the vehicle is not overloaded after occupants get in.
If you cannot find any problems, the speed at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer combination.
Drive at a lower speed to prevent instability. Remember that swaying of the towing vehi-
cle-trailer increases as speed increases.
CAUTION
■Trailer towing precautions
●To tow a trailer safely, use extreme care an d drive the vehicle in accordance with the
trailer’s characteristics and operating conditions. Failure to do so could cause an acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer stability, brake setting an d performance, and the hitch. Your vehicle
will handle differently when towing a trailer.
●Set the vehicle height to the LO mode and turn off the rear height control air suspen-
sion when you connect a trailer, otherwise the vehicle height may change due to the
automatic leveling function, and you may catch part of your body in the vehicle,
resulting in an accident.

■Temporary cancelation of the LDA system
If any of the following occurs, the LDA system
will be temporarily canceled. The functions
will resume after the necessary oper ating conditions have returned.
●The turn signal lever is operated.
●The brake pedal is depressed.
●The vehicle speed deviates from the operating range of the LDA system.
●The lane lines cannot be recognized while driving.
●The wiper operates continuously.
●When the lane departure warning function is activated.
Once the lane departure warning function is activated, it will be temporarily canceled
and resume a few seconds later.
■The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while the audio
system or air conditioning system is in use, it may be difficult to hear the warning sound.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 517) will be dis-
played for a while after driving has started. When the temperature in the cabin decreases
and the temperature around the camera sensor ( P. 228) becomes suitable for its
operation, the functions will begin to operate.

■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 re ar view monitor system, Lexus parking assist
monitor or Multi-terrain Monitor 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 surround ing environment may affect the ability of a
sensor to correctly detect an obstacle. Particular 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 th e 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 co nsiderably 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.
• Towing eyelets are installed.
• The bumper or sensor receives 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 are instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

●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 materials 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 obst acle detection and display. Even at slow
speeds, there is a possibility that 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 sensor 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.

■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.

GX460_OM_OM60K80U_(U)4-6. Driving tips
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 melt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air in let 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, chassis, 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 and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.
