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.

■Lane departure alert function
The warning buzzer may be difficult to hear due to external noise, audio playback, etc.
Also, it may be difficult to f eel steering wheel vibrations due to the road conditions etc.
■Vehicle sway warning function
■White (yellow) lines are only on one side of road
The LDA system will not operate for the side on which white (yellow) lines could not be
recognized. When the system determines that the vehicle is
swaying while the vehicle sway warning function

Some modes may not be selectable depending on the vehicle speed when the
four-wheel drive control switch is in the
H4 position. Refer to the following table.
You can select this mode for easy
access and easy loading of the vehicle.
If the engine switch is turned off within
approximately 30 seconds after the

■Extra high mode
If the vehicle becomes stuck or the Crawl Co
ntrol system requests the vehicle height be
raised, extra high mode may be automatically selected when the vehicle height is in high
mode with the four-wheel drive control switch in the L4 position.
The vehicle height is raised to 0.8 in. (2 0 mm) higher than the high mode height, or
slightly higher.
●Extra high mode will change back to high mode when:
• The vehicle speed exceeds 6 mph (10 km/h)
• The four-wheel drive contro l switch is shifted to H4.
●If you pull the height select switch to “ ” when in extra high mode, normal mode is
selected.
●Extra high mode cannot be manually selected.
■Turning off the height control
●The system will remain off until the height control “OFF” switch is pushed again, even if
the engine switch is turned off.
●Even if the system is turned off, the system will intervene automatically if the vehicle
speed exceeds the following.
• 18 mph (30 km/h) with high or low mode
• 50 mph (80 km/h) with normal mode
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.
●However the vehicle cannot be raised if the vehicle load exceeds the following limits:
• Up to 4 occupants
* plus approximately 661 lb. (300 kg) in the normal mode
• Up to 4 occupants
* plus approximately 441 lb. (200 kg) in the high mode
*: average weight 150 lb. (68 kg) per person
●If the vehicle height cannot be raised when in the normal mode, and “LO” appears on
the display, the vehicle is loaded too heavily. Take extra care when driving in this condi-
tion.
If the vehicle height cannot be raised even after unloading the vehicle, pull the height
select switch to “ ” then push to “ ”. If the vehicle height stil l cannot be raised, turn the
ignition off then on again, then try once more.
■When the vehicle is stopped during driving
The activation of the automatic leveling func tion may cause the vehicle height to change.
This is not a malfunction.
■If the vehicle height does not change
If the vehicle is loaded too heavily, or the undercarriage has come into contact with the
road surface, the vehicle height cannot be raised/lowered.
