■Before towing
Check that the following conditions are
met:
●Ensure that your vehicle’s tires are prop-
erly inflated. ( P.457)
●Trailer tires are inflated according to the
trailer manufacturer’s recommendation.
●All trailer lights work as required by law.
●All lights work each time you connect
them.
●The trailer ball is set at the proper height
for the coupler on the trailer.
●The trailer is level when it is hitched.
Do not drive if the trailer is not level, and
check for improper tongue weight, over-
loading, worn suspension, or other possi-
ble causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all
applicable federal, state/provincial or local regulations. If they do not, install
rear view mirrors appropriate for towing
purposes.
■Adaptive Variable Suspension System
(if equipped)
The suspension can be switched for
improvement in driveability. ( P.278)
■Break-in schedule
If your vehicle is new or equipped with any
new power train components (such as an
engine, transaxle, transfer [AWD models],
rear differential [AWD models] 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 additional load. (See “Warranty
and Services Guide”, “Owner’s Manual
Supplement” or “Scheduled Mainte-
nance”.)
●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 th e accelerator pedal
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

2864-6. Driving tips
WARNING
●After driving through tall grass, mud,
rock, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stone,
sand, etc. adhering or trapped on the
underbody. Clear off any such matter
from the underbody. If the vehicle is
used with these materials trapped or
adhering to the underbody, a break-
down or fire could occur.
●When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump, make sharp turns, strike
objects, etc. This may cause loss of
control or vehicle rollover causing
death or serious injury. You are also
risking expensive damage to your
vehicle’s suspension and chassis.
NOTICE
■To prevent water damage
Take all necessary sa fety measures to
ensure that water da mage to the engine
or other components does not occur.
●Water entering the engine air intake
will cause severe engine damage.
●Water entering the automatic trans-
mission will cause deterioration in shift
quality, locking up of your transmission
accompanied by vibration, and ulti-
mately damage.
●Water can wash the grease from wheel
bearings, causing rusting and prema-
ture failure, and may also enter the dif-
ferential, transmission and transfer
(AWD models only) case, reducing
the gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when
crossing shallow stre ams, 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
around brake discs may affect braking
efficiency and may damage brake sys-
tem 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 maintena nce information,
refer to the “Warranty and Services
Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.

of each system. If non-Lexus parts are used
in replacement or if a repair shop other than

formed by a Lexus dealer

cialists and are kept up to date with the
latest service information. They are well

that the maintenance that has been per-
formed is under warra nty coverage. If any
problem should arise while your vehicle is
