■Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situations,
the communication between the electronic key and the vehicle may be affected,
preventing the smart entry & start system, wireless remote control and immobilizer
system from operating properly.
(Ways of coping: →P. 5 9 1 )
●When the electronic key battery is depleted
●Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
●When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When another wireless key (that emits radio waves) is being used nearby
●When carrying the electronic key together with the following devices that emit
radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

When driving
RX350/270_EE
NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional check the following:
●Brake function
●Changes in quantity and quality of oil and fluid used for the engine, transaxle,
transfer (AWD models), differential, etc.
●Lubricant condition for the propeller shaft (AWD models), bearings and suspen-
sion joints (where possible), and the function of all joints, bearings, etc.

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.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle's roof, chassis, around
the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.

Interior features
RX350/270_EE
■EON (Enhanced Other Network) system (for traffic announcement function)
If the RDS station (with EON data) you are listening to is not broadcasting a traffic
information program and the audio system is in TA (Traffic announcement) mode,
the radio will be switched automatically to a station broadcasting a traffic informa-
tion program in the EON AF list when traffic information begins.
■When the battery is disconnected
All preset stations are erased.
■Reception sensitivity
●It is difficult to maintain perfect radio reception at all times due to the continually
changing position of the antenna, differences in signal strength and surrounding
objects, such as trains and transmitters.
●When is used, automatic station selection and automatic registering of
the stations may not be possible.
●The radio antenna is mounted inside the rear spoiler and 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.
■Digital Audio Broadcast (DAB) radio
The optional radio antenna and tuner are necessary for the use of Digital Audio
Broadcast (DAB) radio.

4-1. Maintenance and care
Cleaning and protecting the vehicle exterior
■Automatic car washes
●Before washing the vehicle:
•Fold the mirrors.
• Turn off the power back door system (if equipped).
●Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle’s paint.
●In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent the vehicle from being cleaned properly or result in
damage to the rear spoiler.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the
windows and the air suspension unit (if equipped).
●Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
Perform the following to protect the vehicle and maintain it in prime condi-
tion:
●Working from top to bottom, liberally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
●For hard-to-remove marks, use car wash soap and rinse thor-
oughly with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
