Extra High Mode; Turning Off The Height Control; Automatic Leveling Function; When The Vehicle Is Stopped During Driving - Lexus LX 570 2016 Service Manual

Extra high mode

■
If the vehicle becomes stuck or the Crawl Control 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. (20 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 control 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
• Up to 4 occupants
*
: 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 still 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 function 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.
