NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during driving, as this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at thesame time to hold the vehicle on a hill.
■When parking the vehicle
Always set the parking brake, and shift the sh ift lever to P. Failure to do so may cause the vehicle to move or the vehicle may accelerate suddenly if the accelerator pedal isaccidentally depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for anextended period of time.
Doing so may damage the power steering motor.
●When driving over bumps in the road, driv e as slowly as possible to avoid damaging the wheels, underside of the vehicle, etc.
●RX200t: Make sure to idle the engine immediately after high speed driving or hillclimbing. Stop the engine only after the turbocharger has cooled down.Failure to do so may cause damage to the turbocharger.
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering wheel firmly and gradually depress the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
●The vehicle will make abnormal sounds or vibrations.
●The vehicle will lean abnormally.
Information on what to do in case of a flat tire ( P. 679, 693)
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain, etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to have any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transaxle, transfer
(AWD models), rear differential (AWD models), etc.
●Lubricant condition for the propeller shaft (AWD models), bearings and suspension joints (where possible), and the func tion of all joints, bearings, etc.

■Important points regarding stability
Vehicle movement resulting from unev en road surfaces and strong cross-
winds will affect handling. The vehicle may also be rocked by passing buses or
large trucks. Frequently check behind when moving alongside such vehicles.
As soon as such vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehicle straight
ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and ensure that
the vehicle-to-vehicle distance is sufficient before executing lane changes.
■Transmission information
To maintain engine braking efficiency and charging system performance,
when using engine braking, do not use the transmission in D. If in the M mode,
the transmission shift range position must be in 4 or lower. ( P. 251)
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures exceeding
30 C (85F) may result in the engine overheating. If the engine coolant tem-
perature gauge indicates that the engine is overheating, turn the air condition-
ing off immediately, leave the road and stop the vehicle in a safe place.
( P. 718)
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and trailer.
Set the parking brake and shift the shift lever to P.

■Auto power off function
If the vehicle is left in ACCESSORY mode for more than 20 minutes or IGNITION ON mode (the engine is not running) for more than an hour with the shift lever in P, the engineswitch will automatically turn off. However, this function cannot entirely prevent battery
discharge. Do not leave the vehicle with the engine switch in ACCESSORY or IGNI- TION ON mode for long periods of time when the engine is not running.
■Electronic key battery depletion

After turning the engine switch off and opening and closing the doors, the steering wheel will be locked due to the steering lock functi on. Operating the engine switch again auto-
matically cancels the steering lock.
■When the steering lock cannot be released
■Steering lock motor overheating prevention
To prevent the steering lock motor from over heating, operation of the motor may be sus-
pended if the engine is turned on and off repeat edly in a short period of time. In this case, refrain from operating the engine switch. After about 10 seconds, the steering lockmotor will resume functioning.
■When “Smart Entry & Start System Malfunction See Owner’s Manual” is displayed onthe multi-information display
The system may be malfunctioning. Have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qua lified and equipped professional immediately.

If the shift lever cannot be shifted with your foot on the brake pedal, there may be a prob-
lem with the shift lock system. Have the vehicle inspected by any authorized Lexus dealer or repairer, or another duly qualifie d and equipped professional immediately. The following steps may be used as an emerge ncy measure to ensure that the shift lever
can be shifted.

WARNING
■Before using LKA system
Do not rely solely upon the LKA system. LKA is not a system which automatically drives the vehicle or reduces the amount of attention that must be paid to the area in
front of the vehicle. The driver must always assume full responsibility for driving safely by always paying careful attention to the surrounding conditions and operate the steer-ing wheel to correct the path of the vehicle. Also, make sure to take adequate breaks
when fatigued, such as from driv ing for a long period of time. Failure to perform appropriate driving operat ions and pay careful attention may lead to an accident, resulting in death or serious injury.
■To avoid operating LKA by mistake
When not using the LKA system, use the LKA switch to turn the system off.
■Situations unsuitable for LKA
Do not use the LKA system in the following situations. The system may not operate properly and le ad to an accident, resulting in death or serious injury.
●A spare tire, tire chains, etc., are equipped.
●When the tires have been excessively worn, or when the tire inflation pressure is low.
●Tires which differ by structure, manufacturer, brand or tread pattern are used.
●Objects or patterns that could be mistaken for white (yellow) lines are present on the side of the road (guardrails, cu rbs, reflective poles, etc.).
●Vehicle is driven on a snow-covered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Asphalt repair marks, white (yellow) line marks, etc., are present due to road repair.
●Vehicle is driven in a temporary lane or restricted lane due to construction work.
●Vehicle is driven on a road surface which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven in traffic lanes other than on highways and freeways.
●Vehicle is driven in a construction zone.
●When your vehicle is towing a trailer or during emergency towing
■Preventing LKA system malfunctions and operations performed by mistake
●Do not modify the headlights or place stic kers, etc., on the surface of the lights.
●Do not modify the suspension etc. If the suspension etc. needs to be replaced, con- tact any authorized Lexus dealer or repair er, or another duly qualified and equipped
professional.
●Do not install or place anything on the hood or grille. Also, do not install a grille guard (bull bars, kangaroo bar, etc.).

■Warning messages and buzzers for dynamic radar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for caution while driv ing. If a warning message is shown on the
multi-information display, read the message and follow the instructions.
■When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when acceleration is required.As the sensor may not be able to correctly detect these types of vehicles, the approach
warning ( P. 336) may not be activated.
