■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of the sensor to correctly detect obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
• The sensor is frozen.
• 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.
• 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
In addition to the examples above, there are instances in which, because of their
shapes, signs and other object s may be judged by the sensor to be closer than they
are.
●The shape of the obstacle may prevent th e sensor from detecting it. Pay particu-
lar attention to the following obstacles.
• Wires, fences, ropes etc.
• Cotton, snow and other materials that absorb radio waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your

2-5. Driving information
(6)If your vehicle will be towing a trailer, load from your trailer will betransferred to your vehicle. Consul t this manual to determine how this
reduces the available cargo and luggage load capacity of your vehi-
cle.
Lexus does not recommend towing a trailer with your vehicle. Your vehicle is
not designed for trailer towing.
Example on your vehicle
Cargo capacity
Total load capacity
When 2 people with the combined weight of 366 lb. (166 kg) are riding
in your vehicle, which has a total load capacity of 825 lb. (375 kg), the
available amount of cargo and luggag e load capacity will be as follows:
825 lb. — 366 lb. = 459 lb. (375 kg —166 kg = 209 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as fol-
lows:
459 lb. — 388 lb. = 71 lb. (209 kg — 176 kg = 33 kg)
As shown in the above example, if the number of occupants increases,
the cargo and luggage load equaling the combined weight of the occu-
pants who got on later, by an amount. In other words, if an increase in the
number of occupants causes an excess of the total load capacity (com-
bined weight of occupants plus cargo and luggage load), you must
reduce the cargo and luggage on your vehicle.
