■Air conditioning system while the engine is stopped by the Stop & Start system
●If the air conditioning system is being used in automatic mode, the fan speed may be reduced or the fan may be stopped while the engine is stopped by the Stop & Start sys-
tem in order to reduce changes in the cabin temperature.
●To ensure air conditioning system performanc e when the vehicle is stopped, disable the Stop & Start system by pressing the Stop & Start cancel switch.
■Changing the idling stop time with the air conditioning system on
The length of time the Stop & Start system will operate when the air conditioning system
is on can be changed on the ( P. 109) or (P. 110). (The length of time the Stop
& Start system will operate when the air condit ioning system is off cannot be changed.)

The sensors may not be able to detect certain objects, such as the following.
●Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic waves.
(People may also not be detected depending on the type of clothing they are wearing.)
●Objects which are not perpendicular to the ground, are not perpendicular to the traveling direction of the vehicle, are uneven or are waving.
●Low objects
●Thin objects such as wires, fences, ropes and signposts

WARNING
■When using the Lexus parking assist monitor system
The parking assist monitor is a supplemental device intended to assist the driver when backing up. When backing up, be sure to check visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in death or serious injuries.
●Never depend on the parking assist monitor entirely when backing up. The imageand the position of the guide lines displayed on the screen may differ from the actualstate.
Use caution, just as you would when backing up any vehicle.
●Be sure to back up slowly, depressing the brake pedal to control vehicle speed.
●If you seem likely to hit nearby vehicles , obstacles, people or mount the shoulder,
depress the brake pedal to stop the vehicle.
●The instructions given are only guidelines. When and how much to turn the steering wheel will vary according to traffic condi-
tions, road surface conditions, vehicle condition, etc. when parking. It is necessary to be fully aware of this before using the parking assist system.
●When parking, be sure to check that th e parking space will accommodate your vehi-
cle before maneuvering into it.
●Do not use the parking assist monitor in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires • When the back door is not closed completely• On roads that are not flat or straight, such as curves or slopes.
●In low temperatures, the screen may darken or the image may become faint. Theimage could distort when the vehicle is moving, or you may become unable to see the
image on the screen. Be sure to check direct visually and with the mirrors all around the vehicle before proceeding.
●If the tire sizes are changed, the position of the guide lines displayed on the screen
may change.
●The camera uses a special lens. The distances between objects and pedestrians that appear in the image displayed on the screen will differ from the actual distances.
( P. 409)
●Estimated course line display mode: If the steering wheel is straight and the vehicle width guide lines and the estimated course lin es are not in alignment, have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
