When driving
■Extra high mode
If the vehicle becomes stuck, extra high mode may be automatically selected when
the vehicle height is in high mode with the four-wheel drive control lever in the “L”
position.
The vehicle height is raised to 2.8 in. (70 mm) higher than the normal mode height,
or slightly higher.
Extra high mode will change back to high mode when:
• The vehicle is no longer stuck
• The four-wheel drive control lever is shifted to a position other than “L”
●If you push “ ▼” when in extra high mode, normal mode is selected.
●Extra high mode cannot be manually selected.
■Turning off the active height control suspension
●The system will remain off until the switch is pushed again, even if the ignition is
turned off.
●Even if AHC is turned off, the system automatically selects the normal mode if
the vehicle's speed exceeds 19 mph (30 km/h).
■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 approximatel y 375 lb. (170 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” is lit
on the height mode indicator, the vehicle is loaded too heavily. Take extra care
when driving in this condition.
If the vehicle height cannot be raised even after unloading the vehicle, press
“ ▼ ” then “ ▲” on the height mode select switch. If the vehicle height still cannot
be raised, turn the ignition off th en on again, then try once more.

■Parking and stopping tips
●If you immediately stop the engine after off-road driving, or park the vehicle for
a long time, the vehicle height may gradually lower. When parking, make 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 slop e, or with the selector 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 propel ler shaft. This does not indicate a mal-
function.
■Continued system operation
Even if the engine is stopped while the ve hicle height is being lowered, operation
will continue for up to 12 seconds.
■Active height control failure warning
●If a malfunction occurs in the AHC system, normal mode is automatically
selected.
The height control “ OFF” indicator will bl ink, and AHC cannot be activated until
the malfunction is corrected.
Stop the engine and start it again. If the height control “OFF” indicator light
turns off, the system is operating correc tly. If the indicator light continues to
blink, have the vehicle checked at your Lexus dealer as soon as possible.
●If the height control “OFF” indicator light does not come on when the ignition
switch is turned on, there is a malfunction in the AHC system. You can continue
normal driving, however have the vehicle checked by your Lexus dealer as soon
as possible.
■Installing or removing heavy equipment
If the equipment exceeds 33 lb. (15 kg), the front torsion bar must be adjusted. See
your Lexus dealer.

■Advice for driving on slippery roads in “L” (low speed position)
●If you shift the four-wheel drive control lever to “L” and the shift lever to “2” while
driving in steep off-road areas, the output of the brake can be controlled effec-
tively by the active traction control system, which assists the driver to control the
driving power of 4 wheels.
●Use the “L” position of the shift lever for maximum power and traction when
your wheels get stuck or when you drive down a steep incline. In the following
cases, the output of the brake can be co ntrolled by the active traction control
system if the engine speed is un der 3,000 rpm (normally under 3,000 rpm
when the wheels get unstuck).
• The four-wheel drive control lever in the “L” position and the shift lever in the
“L” position or the shift lever in the “D”, “4”, “3” or “2” with the transmission
downshifting to first gear.
• The four-wheel drive control lever in the “L” position and the shift lever in the
“R” position.
■The center differential lock/unlock button can be operated when
●The ignition key is in the “ON” position, and
●The four-wheel drive control lever is in the “H” or “L” position.
■Locking /unlocking the center differential
●When the center differential is locked, VSC (vehicle stability control) is auto-
matically turned off. (Center differenti al lock and “VSC OFF” indicator light
come on.)
●When the operation is not completed, th e center differential lock indicator
blinks. If the indicator light does not go off when unlocking the center differen-
tial, drive straight ahead while accelerating or decelerating, or drive in reverse.
●The center differential lock system operation is not completed within 5 seconds
while the cruise control system is set, cancel the cruise control system.
