GX460_OM_OM60Q84U_(U)4-1. Before driving
■AVS (adaptive variable suspension system)
The suspension can be switched fo
r improvement in driveability. (P. 345)
■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 towing.
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 trailer, and avoid full throttle acceleration.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to the addi-
tional load. (See “Owner’s Guide”, “Warranty and Services Guide”, “Owner’s Manual
Supplement” or “Warranty Booklet”.)
●Retighten the fixing bolts of the towing ba ll and bracket after approximately 600 miles
(1000 km) of trailer towing.
■If trailer sway occurs
One or more factors (crosswinds, passing ve hicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer, causing instability.
●If trailer swaying occurs:
• Firmly grip the steering wh eel. Steer straight ahead.
Do not try to control trailer sway ing by turning the steering wheel.
• Begin releasing the accelerator pedal im mediately but very gradually to reduce
speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the st eering or brakes, your vehicle and trailer
should stabilize.

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage 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 damage.
●Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differentials, tr ansmission and transfer case, reducing the
gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when cro ssing shallow streams, first check the depth of
the water and the bottom of the riverbed 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 afte r each day of off-road driving that has
taken you through rough terrain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Se rvices Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

Maintenance and care
■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure performance
of each system. If non-Lexus parts are used in replacement or if a repair shop other than
a Lexus dealer performs repairs, confirm the warranty coverage.
