travel.
●Respect private property. Get owner’s permission before entering private
property.
●Do not enter areas that are closed. Honor gates, barriers and signs that
restrict travel.
●Stay on established road s. When conditions are wet, driving techniques
should be changed or travel dela yed to prevent damage to roads.

WARNING
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, serious injury
or damage to your vehicle:
●Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous places.
●Do not grip the steering wheel spokes when driving off-road. A bad bump could jerk
the wheel and injure your hands. Keep both hands and especially your thumbs on the
outside of the rim.
●Always check your brakes for effectiveness immediately after driving in sand, mud,
water or snow.
●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 materi-
als trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain , do not drive at excessive speeds, jump,
make sharp turns, strike obje cts, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.
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 damage.
●Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differential, transmission and transfer (AWD models only)
case, reducing the gear oi l’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 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 Services Guide/Owner’s Manual Supple-
ment/Scheduled Maintenance”.

4225-4. Using the radio
RX350/RX350L_U
HD Radio™ Technology is the digital evolution of analog AM/FM radio. Your
radio product has a special receiver which allows it to receive digital broadcasts
(where available) in addition to the analog broadcasts it already receives.
Digital broadcasts have better sound qua lity than analog broadcasts as digital
broadcasts provide free, crystal clear audio with no static or distortion. For more
information, and a guide to available radio stations and programming, refer to
www.hdradio.com
.
“HD Radio features included in Lexus radios:
Digital Sound - HD Radio broadcasts deliver crystal-clear, digital audio quality to
listeners.
HD2/HD3 Channels - FM stations can prov ide additional digital only audio pro-
gramming with expanded content and format choices on HD2/HD3 channels.
PSD - Program Service Data (PSD) gives you on-screen information such as art-
ist name and song title.
iTunes Tagging - Listeners can tag (store) songs they like for later review and pur-
chase through iTunes.
Artist Experience - Images related to the broadcast are displayed on the radio
screen, such as album cover art and station logos.”

■HD Radio™ Technology troubleshooting guide
■Reception sensitivity
●Maintaining perfect radio reception at all times is difficult due to the continually chang-
ing position of the antenna, differences in si gnal strength and surrounding objects, such
as trains, transmitters, etc.
●The radio antenna is mounted inside the rear window. To maintain clear radio reception,
do not attach metallic window tinting or other metallic objects to the antenna wire
mounted inside the rear window.
