When driving
LX570_OM_OM60L21U_(U) CAUTION■
When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident. ●
Do not use the sensor at speeds in excess of 6 mph (10 km/h). ●
The sensors’ detection areas and reaction times are limited. When moving for-
ward or reversing, check the areas surrounding the vehicle (especially the sides
of the vehicle) for safety, and drive slowly, using the brake to control the vehicle’s
speed. ●
Do not install accessories within the sensors’ detection areas.
NOTICE■
When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor
malfunction etc. Have the vehicle checked by your Lexus dealer. ●
A beep does not sound when you turn the main switch on. ●
The intuitive parking assist operation disp lay flashes, and a beep sounds when no
obstacles are detected. ●
If the area around a sensor collides wi th something, or is subjected to strong
impact. ●
If the bumper collides with something. ●
If the display shows continuously without a beep. ●
If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is likely that
the sensor is malfunctioning.■
Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

LX570_OM_OM60L21U_(U) ■ Using the system when parallel parking
Screen display and beep sounds
provide an estimation of the point
at which you should turn the steer-
ing wheel when parallel parking. If
the position the vehicle is to be
parked in is narrower than usual,
narrow mode can be used.
Each time you touch the narrow
mode screen on-off button, the
narrow mode and the normal
mode are switched.
■ Switching the parking mode screen
Each time you touch the parking
mode switch screen button, the
perpendicular parking mode and
parallel parking mode are
switched.

When driving
LX570_OM_OM60L21U_(U) Conditions for changing the vehicle height mode
Some modes may not be selectable depending on the vehicle speed
when the four-wheel drive control swit ch is in the “H4” position. Refer to
the following table.
Easy access mode
You can select this mode for easy
access and easy loading of the
vehicle.
If the “ENGINE START STOP” switch is turned to OFF within 30 seconds after
the vehicle stops while this mode is on, the vehicle height is lowered automati-
cally.
When the vehicle begins to lower a beep will sound twice, and while the vehicle
is lowering the indicator light will flash to alert the driver and surrounding people
that the vehicle is lowering. Low mode Normal mode High mode
Under 7 mph (12 km/h) Ye s Ye s Ye s
7 mph (12 km/h) to
18 mph (30 km/h) No Ye s Ye s
18 mph (30 km/h) or over No Ye s No

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 no t indicate a malfunc-
tion. ■
4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC, normal mode is automatically
selected. However, the system may not sw itch to normal mode depending on the
location of the malfunction.
The warning message is displayed on th e multi-information display, and the 4-
Wheel AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If th e warning message turns off, the system is
operating correctly. If the warning messag e continues to be displayed, have the
vehicle checked at your Lexus dealer as soon as possible.

If the low speed four-wheel drive indicator light or the center differential lock
indicator light blinks ●
If the low speed four-wheel drive indicator light continues to blink when using
the four-wheel drive control switch, stop the vehicle completely, move the shift
lever to “N” and operate the switch again. ●
If the shift lever is moved before the low speed four-wheel drive indicator turns
on/off, the transfer mode may not be shifted completely. The transfer mode dis-
engages both the front and rear driveshafts from the powertrain and allows the
vehicle to move regardless of the shift po sition. (At this time, the indicator blinks
and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in “P”.
You or someone else could be seriously injured. You must complete the shifting of
the transfer mode.
To complete the shifting, stop the vehicle completely, return the shift lever to “N”,
and confirm that the shift was completed (the indicator turns on/off). ●
If the engine coolant temperature is too low, the four-wheel drive control system
may not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indi-
cator light continues to blink even after attempting the above, there may be a mal-
function in the engine, the brake system or the four-wheel drive system. In this case,
you may not be able to shif t between “H4” and “L4”, and the center differential lock
may not be operable. Have the vehicle inspected by your Lexus dealer immediately.

LX570_OM_OM60L21U_(U) CAUTION■
While driving
Never move the four-wheel drive control switch if the wheels have lost traction.
Doing so may cause an accident resu lting in death or serious injury.■
When the vehicle is parked
If the shift lever is moved before the low speed four-wheel drive indicator turns on/
off, the transfer mode may not be shifte d completely. The transfer mode disengages
both the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (A t this time, the indicator blinks and the
buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in “P”. You
or someone else could be se riously injured. You must complete the shifting of the
transfer mode. (  P. 3 3 0 )
NOTICE■
To prevent damage to the center differential ●
For normal driving on dry and hard surface roads, unlock the center differential.●
Unlock the center differential after the wheels are out of the ditch or off the slip-
pery or bumpy surface. ●
Do not push the center differential lock/u nlock switch when the vehicle is turning
or when its wheels are spinni ng freely off the ground.

Function limitations
Crawl Control ●
In the following situations, brake control can be used to drive downhill at a con-
stant speed. However, engine control is not available when driving uphill at a
constant speed.
• When switched to second start mode. ●
In the following situation, engine control and brake control will stop temporarily.
In this event, the Crawl Control indicator will flash.
• When the vehicle speed exceeds approximately 15 mph (25 km/h).
Tu r n A s s i s t f u n c t i o n
In the following situations, the Turn Assist fu nction will stop temporarily. In this event,
the Turn Assist indicator will flash. ●
When the vehicle speed exceeds approximately 6 mph (10 km/h).●
When the shift lever is moved to “R”.■
When the Crawl Control system is operated continuously ●
If Crawl Control is used continuously for a long time, the buzzer will sound, a
malfunction notification will be displaye d on the multi-information display, the
Crawl Control indicator will go off, and Crawl Control will be temporarily inop-
erable as a result of the brake system over heating. In this event, stop the vehicle
immediately in a safe place, and allow the brake system to cool down sufficiently
until the “TRAC OFF” on the multi-inform ation display goes off. (In the mean-
time, normal driving is possible.) ●
If Crawl Control is used continuously for a long time, the buzzer will sound, the
system will be temporarily canceled, and a malfunction notification will be dis-
played on the multi-information display as a result of the automatic transmission
system overheating. Stop the vehicle in a safe place until the display goes off.
