again to turn the defogger off. Continuous use may cause the battery
to discharge, especially during stopandgo driving. The defogger
is not designed to dry rain water or to melt snow.
If the outside rear view mirrors are heavily coated with ice, use a
spray deicer before operating the switch.
NOTICE
When cleaning the inside of the rear window, be careful not
to scratch or damage the heater wires.
To prevent the battery from being discharged, do not operate
the defogger continuously longer than necessary.

COMFORT ADJUSTMENT
114The beep sound means that the positions are recorded in the
computer ’s memory.
By repeating these two steps and pressing the remaining button, the
driving position for another driver can be recorded.
To set a new memorized position, select the desired position and
perform step 2. The previous memory will be erased and the new
position will be set.
To make only slight changes to an already memorized position, the
easiest way is to first activate the memorized position, then make the
desired changes and perform step 2 above.
Activating a memorized position
16L056
When you push button ”1” or ”2”, the driving position will be
automatically adjusted to the position recorded for that button.Conditions for memorized position activation
Ignition key ”ON” and shift lever in ”P” position.
All parts of the memorized positions can be activated.
However, if the brake pedal is being depressed, the seat position
will not change.
Key not in ignition switch and within 30 seconds of opening
driver’s door.
The memorized position can be activated, except for the tilt and
telescopic steering.
If any driving position memory switch is pushed while one of the
memorized driving position profiles is being activated, the operation
will stop.
To activate the system, push the desired button (”1” or ”2”) again.
The driving position memory control system cannot be operated
while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s memory will
be erased and the memorized positions will have to be set again.
CAUTION
Do not start the vehicle while the adjustments are being
made.
Take care not to select the wrong button, or the seat could
strike the rear passenger or hit your body against the
steering wheel. If this happens, you can stop the movement
by pressing another driving position memory switch, or
depressing the brake pedal.

AIR CONDITIONING AND AUDIO
134
Using your audio system: some basics
This section describes some of the basic features of the Lexus audio
system. Some information may not pertain to your system.
Your audio system works when the ignition key is in the ”ACC” or
”ON” position.
NOTICE
To prevent the battery from being discharged, do not leave the
car audio on longer than necessary when the engine is not
running.
(a) Turning the system on and off
20L002-1
Push this knob to turn the audio system on and off. Turn this
knob to adjust the volume.
The system turns on in the last mode used.
20L042-2
Push ”AM”, ”FM1/2”, ”TAPE” or ”CD” to turn on that mode.
The selected mode turns on directly.
Push these buttons if you want to switch from one mode to another.
If the tape or disc is not set, the cassette player or compact disc player
does not turn on.
You can turn off the cassette player by ejecting the cassette tape. If
the audio system was previously off, then the entire audio system
will be turned off when you eject the cassette tape. If another
function was previously playing, it will come on again.

DRIVING TIPS
182Do not rest your foot on the brake pedal while driving. It
can cause dangerous overheating, needless wear, and poor
fuel economy.
To drive down a long or steep hill, reduce your speed and
downshift. Remember, if you ride the brakes excessively,
they may overheat and not work properly. See page 163.
Be careful when accelerating, upshifting, downshifting or
braking on a slippery surface. The abrupt change in engine
speed, such as sudden acceleration or engine braking, could
cause the vehicle to spin or skid.
Do not drive in excess of the speed limit. Even if the legal
speed limit permits it, do not drive over 140 km/h (85 mph)
unless your vehicle has highspeed capability tires.
Driving over 140 km/h (85 mph) may result in tire failure,
loss of control and possible injury. Be sure to consult a tire
dealer to determine whether the tires on your vehicle are
highspeed capability tires or not before driving at such
speeds.
Do not continue normal driving when the brakes are wet.
If they are wet, your vehicle will require a longer stopping
distance, and it may pull to one side when the brakes are
applied. Also, the parking brake will not hold the vehicle
securely.
WINTER DRIVING TIPS
Make sure you have ethyleneglycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it must be
in top shape to provide enough power for winter starting. Page 253
tells you how to visually inspect the battery. Your Lexus dealer and
most service stations will be pleased to check the battery charge
level.
Make sure the engine oil viscosity is suitable for the cold weather.
See page 232 for recommended viscosity. Leaving a heavy summer
oil in your vehicle during winter months may cause harder starting.
If you are not sure about which oil to use, call your Lexus dealer
they will be pleased to help.
Check the electronic ignition system for loose connections or
obvious damage.
Keep the door locks from freezing.
Squirt lock deicer or glycerine into the locks to keep them from
freezing.
