■Temporary cancelation of the LDA system
If any of the following occurs, the LDA system will be temporarily canceled.
The function will resume after the necessary operating conditions have returned.
●The vehicle speed deviates from the operating range of the LDA system.
●The turn signal lever is operated.
●When the lane lines cannot be recognized while driving.
●When the lane departure warning sounds.
The lane departure warning function will not operate again for a several seconds
after it has been activated, even if the vehicle leaves the lane again.
■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 warn-
ing sound.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 646) 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. 273) becomes suit-
able for its operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane markers
could not be recognized.

■Intuitive parking assist display
When an obstacle is detected while the rear view monitor system is in use, the warn-
ing indicator will appear in the top right of the screen even if the display setting has
been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s front cor-
ners and rear bumper.
●Certain vehicle conditions and the surrou nding 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. (Wiping the sensors will resolve this problem.)
• 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 abnor-
mal display, or obstacle s 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.
• 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 th e 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 the se nsor to be closer than they
are.

●The shape of the obstacle may prevent the sensor from detecting it. Pay particular
attention 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 vehicle
●The following situations may occur during use.
• Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection 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 warning beep sounds.
• Thin posts or objects lower than the se nsor may not be detected for collision
when approached, even if they have been detected once.
• It might be difficult to hear beeps due to the volume of audio system or air flow noise of air conditioning system.

■Operation of the air conditioning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the air
conditioning system to en hance fuel efficiency (P. 474). To improve air condition-
ing performance, adjust the fan sp eed or turn off Eco drive mode.
■Sport mode automatic deactivation
Sport mode is automatically deactivated if the “START STOP ENGINE”
<“POWER”> switch is turned off after driving in sport mode.

Hybrid vehicle driving tips (hybrid vehicles)
When using Eco drive mode, the torque corresponding to the accelerator
pedal depression amount can be generated more smoothly than it is in
normal conditions. In addi tion, the operation of the air conditioning system
(heating/cooling) will be minimized, improving the fuel economy.
( P. 311)
The Eco-friendly driving is possible by keeping the indicate of Hybrid Sys-
tem Indicator within Eco area. ( P. 100)
Make sure to operate the brakes gently and in good time. A greater
amount of electrical energy can be retained when slowing down.
Repeated acceleration and deceleration , as well as long waits at traffic
lights, will lead to bad fuel consumpti on. Check traffic reports before leav-
ing and avoid delays as much as possible. When encountering a delay,
gently release the brake pedal to allow the vehicle to move forward
slightly while avoi ding overuse of the accelerator pedal. Doing so can help
control excessive gasoline consumption.
For economical and ecological drivin g, pay attention to the following

Control your speed and keep at a constant speed. Also, before stopping
at a toll booth or similar, allow plenty of time to release the accelerator and
gently apply the brakes. A greater am ount of electrical energy can be
retained when slowing down.
Use the air conditioning only when ne cessary. Doing so can help control
excessive gasoline consumption.
In summer: In high temperatures, use th e recirculated air mode. Doing so
will help to reduce the burden on th e air conditioner and reduce fuel con-
sumption as well.
In winter: Because the gasoline engine will not automatically cut out until
the gasoline engine and the interior of the vehicle are warm, it will con-
sume fuel. Also, fuel consumption can be improved by avoiding overuse of
the heater.
Make sure to check the tire inflati on pressure frequently. Improper tire
inflation pressure can cause poor fuel consumption.
Also, as snow tires can cause large am ounts of friction, their use on dry
roads can lead to poor fuel consumptio n. Use a tire that is appropriate for
the season.
Carrying heavy luggage can lead to poor fuel consumption. Avoid carry-
ing unnecessary luggage. Installing a la rge roof rack can also cause poor
fuel consumption.

4-6. Driving tips
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 immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove
any snow that has accumulated on the air inlet vents in front of the wind-
shield.
●Check for and remove any excess ice or snow that may have accumu-
lated on the exterior lights, vehicle’s roof, chassis, around the tires or on
the brakes.
●Remove any snow or mud from the bo ttom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the
vehicle ahead, and drive at a reduced speed suitable to road conditions.
Park the vehicle and move the shift lever to P without setting the parking
brake. The parking brake may freeze up, preventing it from being
released. If necessary, block the wheels to prevent inadvertent sliding or
creeping.
