2-5. Driving information
RX350/270_EE
NOTICE
■To prevent 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 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 (AWD
models), reducing 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 stream 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 effi-
ciency 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.

■Tire info rmat ion
●Ensure that your vehicle’s tires are properly inflated. Adjust the tire pressure to
the recommended pressure. (→P. 6 1 7 )
●Increase the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
■Trailer lights
●Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Directly wiring up to your vehicle may damage the
electrical system and stop the lights from functioning correctly.
●Please consult at any authorized dealer or repairer, or another duly qualified
and equipped professional when installing trailer lights, as incorrect installation
may cause damage to the vehicle’s lights. Please take care to comply with your
state’s laws when installing trailer lights.
■Break-in schedule
Lexus recommends that vehicles fitted with new power train components should
not be used for towing trailers for the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the
load exerted on the vehicle. Also make sure that you will not be towing a load
that exceeds the maximum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mirrors should be added to the vehicle if the
traffic behind cannot be clearly seen with standard mirrors. Adjust the extend-
ing arms of these mirrors on both sides of the vehicle so that they always provide
maximum visibility of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to
normal driving.
●Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
