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 co ntrol “OFF” switch is pushed again, even if
the engine switch is turned off. ●
Even if the system is turned off, the system will interven e 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 heig ht cannot be raised/lowered.

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 un der the vehicle that may come
in contact with the underbody. The vehicle will return to th e 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-informatio n 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.
