Advice for driving on slippery roads ●
If you shift the four-wheel drive control sw itch to “L4” and the shift lever to the
“2” range of “S” or “D” (vehicles with paddle shift switches) while driving in
steep off-road areas, the output of the brake can be controlled effectively by the
Active TRAC, which assists the driver to control the driving power of 4 wheels. ●
Use the “1” range of “S” or “D” (vehicles with paddle shift switches) of the shift
lever for maximum power and traction when your wheels get stuck or when
driving down a steep incline.■
The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential. ■
The center differential lock/unlock switch can be operated when ●
The “ENGINE START STOP” switch is in IGNITION ON mode. ●
The vehicle speed is less than 60 mph (100 km/h).■
Locking/unlocking the center differential ●
When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator lights come on.) ●
If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse. ●
If the center differential lock/unlock is not completed within 5 seconds while the
cruise control system is on, ca ncel the cruise control system.

LX570_OM_OM60L21U_(U) ■
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.

LX570_OM_OM60L21U_(U) Crawl Control (with Turn Assist function) Allows travel on extremely rough off-road surfaces at a fixed low speed
without pressing the accelerator or br ake pedal. Minimizes loss of traction
or vehicle slip when driving on slippery road surfaces, allowing for stable
driving.

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.
