LDA (Lane Departure Alert)
When driving on roads with white (yellow)
lines, this function alerts the driver
when the vehicle might depart from its lane.
The LDA system recognizes visible
white (yellow) lines with the camera
sensor on the upper portion of the front
windshield.
◆Lane departure alert function
When the system determines that
the vehicle might depart from its
lane, a warning is displayed on the
multi-information display, and either
the warning buzzer sounds or the
steering wheel vibrates to alert the
driver.
When the warning buzzer sounds or
the steering wheel vibrates, check
the surrounding road situation and
carefully operate the steering wheel
to move the vehicle back to the cen-
ter of the lane.

WARNING
■Before using LDA system
Do not rely solely upon the LDA system. The LDA system does not automatically drive
the vehicle or reduce 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 pay-
ing careful attention to the surrounding cond itions and operating the steering wheel to
correct the path of the vehicle. Also, the driver must take adequate breaks when
fatigued, such as from driving 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 LDA system by mistake
When not using the LDA system, use the LDA switch to turn the system off.

correctly
In the case of the following conditions, o perate the brake pedal (or accelerator pedal,
depending on the situ ation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not
operate properly.
●When the vehicle ahead of you decelerates suddenly
●When driving on a road surrounded by a struct ure, such as in a tunnel or on a bridge
●While the vehicle speed is decreasing to the set speed after the vehicle accelerates by
depressing the accelerator pedal
●When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)

■In the following cases the 4-Wheel AHC will not operate
●The brake pedal has been depressed for a few seconds or longer while the vehicle is
stopped.
●Vehicle height control has not been frequently used.
●The suspension fluid temperature is lower than -22°F (-30°C).
●There is ice on the suspension.
●Driving on bumpy roads which may caus e the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the center dif-
ferential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid temperature
drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C).
●In this case, even if the height select switch is pressed, the vehicle height will not change.
Once the vehicle has been driven for a sh ort time and the suspension fluid has been
warmed to within normal operating limits , the 4-Wheel AHC will begin operating and
the vehicle height will automatically change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not be able
to be raised, even if the 4-Wheel AHC is operating. In this case, pull the height select
switch to “” then push to “ ” after driving for a short time longer to select the desired
vehicle height.
■Parking and stopping tips
●If you immediately stop the en gine after off-road driving, the vehicle height may gradu-
ally lower. When parking, ma ke sure there is nothing under the vehicle that may come
in contact with the underbody. The vehicle will return to the set height when the engine
is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other than P
or N while the vehicle is stopped, you may hear a sound caused by the expansion and
contraction of the propeller shaft. This does not indicate a malfunction.
■4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC , normal mode is automatically selected.
However, the system may not switch to norm al mode depending on the location of the
malfunction.
The warning message is displa yed on the multi-information display, and the 4-Wheel
AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the wa rning message turns off, the system is operat-
ing correctly. If the warning me ssage continues to be displayed, have the vehicle checked
at your Lexus dealer as soon as possible.
