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.

When driving
LX570_OM_OM60L21U_(U) NOTICE■
To prevent the water damage
Take all necessary safety measures to en sure that water dama ge to the engine or
other components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age. ●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the river bed for firmness. Drive slowly and
avoid deep water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.

3922-5. Driving information
LX570_OM_OM60L21U_(U) ● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the tr ailer wheels will be closer than the
vehicle wheels to the inside of the turn. Co mpensate by making a
wider than normal turning radius.
● Slow down before making a turn, in crosswinds, on wet or slippery sur-
faces, etc.
Increasing vehicle speed ca n destabilize the trailer.
● Take care when passing other vehi cles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in “D”.
If in the S mode, the transmission shift range position must be in 5 or
lower.
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do not
make sudden downshifts while descending steep or long downhill
grades.
● Avoid holding the brake pedal down too long or applying the brakes
too frequently. This could cause th e brakes to overheat and result in
reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85°F [30°C]) when driving up a
long or steep grade. If the eng ine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. ( P. 873)

When driving
LX570_OM_OM60L21U_(U) ● Always place wheel bloc ks under both the vehi cle’s and the trailer’s
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in “P”. Avoi d parking on a slope, bu t if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle’s and
trailer’s wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into “P” and turn off the engine.
● When restarting after parking on a slope:
With the transmission in “P”, start the engine. Be su re to keep the
brake pedal pressed.
Shift into “D” or “R” (if reversing).
Release the parking brake and br ake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks. STEP 1

AVS (adaptive variable suspension system)
The suspension can be switched for improvement in driveability. ( P. 3 2 9 )■
Break-in schedule
If your vehicle is new or equipped with any new power train components (such as
an engine, transmission, differential or wheel bearing), Lexus recommends that you
do not tow a trailer until the vehicle has been driven for over 500 miles (800 km).
After the vehicle has been driven for over 500 miles (800 km), you can start tow-
ing. However, for the next 500 miles (800 km), drive the vehicle at a speed of less
than 50 mph (80 km/h) when towing a traile r, and avoid full throttle acceleration.■
Maintenance ●
If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Owner’s Guide”, “Warranty and Services Guide”,
“Owner’s Manual Supplement” or “Warranty Booklet”.) ●
Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.■
If trailer sway occurs
One or more factors (crosswinds, passing vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability. ●
If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
• Begin releasing the accelerator peda l immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle and
trailer should stabilize. (if enabled, Trailer Sway Control can also help to stabilize the
vehicle and trailer.)

When trouble arises
8135-1. Essential information
LX570_OM_OM60L21U_(U) If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission. Contact
your Lexus dealer, before towing.
● The engine is running, but the vehicle will not move.
● The vehicle makes an abnormal sound. If towing is necessary, we recommend having your vehicle towed by your
Lexus dealer or a commercial towing se rvice, using a lift-type truck or a flat
bed truck.
Use a safety chain system for all towi ng, and abide by all state/provincial
and local laws.
Use a towing dolly or flat bed truck.
