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”.

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.)

LX570_OM_OM60L21U_(U) Emergency towing
If a tow truck is not available, in an emergency your vehicle may be tem-
porarily towed using a cable or cha in secured to the towing hook. This
should only be attempted on hard, surfaced roads for short distances at
low speeds.
A driver must be in the vehicle to s teer and operate the brakes. The vehi-
cle’s wheels, drive train, axles, steering and brakes must be in good condi-
tion.

8265-2. Steps to take in an emergency
LX570_OM_OM60L21U_(U) ■
If the malfunction indicator lamp comes on while driving
First check the following: ●
Is the fuel empty?
If it is, fill the fuel tank immediately. ●
Is the fuel tank cap loose?
If it is, tighten it securely.
The malfunction indicator lamp will go off after taking several driving trips.
If the malfunction indicator lamp does not go off even after several trips, contact
your Lexus dealer as soon as possible. ■
If the low speed four-wheel drive indicator light or the center differential lock
indicator light blinks
Take the specified steps. (  P. 333)
If the brake system warning light or the ma lfunction indicator light also comes on, or
the low speed four-wheel drive indicator light or the center differential lock indica-
tor light continues to blink after taking th e specified steps, there may be a malfunc-
tion in the engine, the brake system or the four-wheel drive system. In this case, you
may not be able to transfer between “H4” and “L4” modes, and the center differen-
tial lock may not be able to be locked or unlocked. Have the vehicle inspected by
your Lexus dealer, immediately. ■
Front passenger detection sensor and passenger seat belt reminder●
If luggage is placed on the front passenger seat, the front passenger detection
sensor may cause the warning light to flash, even if a passenger is not sitting in
the seat. ●
If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
